The main purpose of street lighting is to ensure the safety of road users at night.
The main parameters that, according to Russian standards, are still decisive for street lighting:
- average brightness of the road surface,
- uniform distribution of road surface brightness,
- lamp life.
There are also additional parameters (luminous flux pulsation, color rendering index, correlated color temperature), which, of course, affect traffic safety, but, unfortunately, are still not standardized for street lighting. It should be noted that recently they have begun to pay more attention, and you need to be prepared for the fact that in the near future they will enter the standards.
Advantages of LED lamps in comparison with gas-discharge lamps
The main task of developers and manufacturers of lighting fixtures is to ensure that street lighting standards are met with minimal energy consumption and maximum service life.
This is precisely the main advantage of light-emitting diode (LED) lamps in comparison with gas-discharge lamps - high luminous efficiency and low power consumption.
This is achieved by several factors: the LED itself is a very highly efficient converter of electrical energy into light. Currently, there are LEDs in mass production with an efficiency of more than 200 lm / W, and laboratory samples have an efficiency of about 300 lm / W. For comparison, commercially available high-power sodium lamps have an efficiency of 130 lm / W, mercury - no more than 60 lm / W, and low-power lamps have an even lower efficiency - 80 and 40 lm / W, respectively.
The second factor that allows street LED lamps to achieve high efficiency in operation is the direction of radiation. LEDs shine only in one direction, which allows you to get the efficiency of the lamp up to 96%!!! Discharge lamps shine in all directions, they require a special reflector to redirect the light in the right direction, and this significantly reduces the efficiency of the device. Taking into account the protective glass, the efficiency of standard lamps with gas discharge lamps does not exceed 75%.
For example, an 85 W LED lamp gives the same luminous flux (9750 lm) as a lamp with a 250 W mercury lamp, consuming 260 W (3 times energy savings!!!)
It should also be taken into account that these efficiency values are achieved with new, newly installed lamps. But LED lamps have another fundamental advantage: slower degradation of the luminous flux over time. Therefore, in the calculations, you can put a smaller safety factor.
Also, in the course of actual operation, it turned out that the decrease in the luminous flux caused by dust in gas-discharge lamps is an order of magnitude higher than that of LED lamps, since LED lamps have only one surface subject to pollution (see figure).
It is important not only to produce the maximum luminous flux, but also to distribute it correctly. LED lamps and here have an advantage over gas-discharge lamps. The small size of LEDs makes it possible to develop and produce lenses and reflectors for them that use the light flux more efficiently to ensure maximum uniformity of the road surface brightness distribution and maximum optical efficiency of the luminaire compared to reflectors for bulky gas discharge lamps.
Service life of LED lamps - more than 50,000 hours (over 12 years). All elements of the lamp are durable, unlike lamps with gas discharge lamps. For comparison, the service life of mercury lamps of the DRL series is 8,000 hours, the best sodium lamps of the DNaT series are 20,000 hours.
Consider the additional benefits of LED lamps, which are also important for traffic safety:
- Low frequency light pulses. In traditional gas-discharge lamps, the light pulsation is about 80-100%. This increases driver fatigue and causes a stroboscopic effect, which increases the likelihood of an accident. For most LED lamps, the ripple does not exceed 10-20%.
- Color rendering index. The color rendering index of LED lamps is 70-90, mercury lamps - 40-60, sodium lamps - 30-40. Taking into account the peculiarities of human twilight vision, the visibility of objects when illuminated with LED lamps is several times higher than when illuminated with sodium lamps. This increases the reaction speed of road users and reduces accidents on the roads.
- Correlated color temperature. A wide range of LED color temperatures (2400-10000 K) makes it possible to highlight sections of the road that are especially important in terms of safety. For example, the main part of the road is illuminated with light with a color temperature of 6000K (cold color), and pedestrian crossings are highlighted with light with a color temperature of 3000K (warm color).
- Instant switching on when the supply voltage is applied and stable performance at any temperature throughout the Russian Federation. Luminaires with DRL and HPS lamps are extremely unsatisfactorily started at temperatures below -15 ° C, and reaching the mode takes 10-20 minutes.
- Instantaneous reactivation. In gas-discharge lamps, it will take several minutes for the lamp to cool down before it can be switched on again.
- No starting currents. The initial current of LED lamps exceeds the rated current by only 15-20%, the starting current of gas-discharge lamps is 2-3 times higher than the rated current.
- With an increased input voltage, the power consumption of gas-discharge lamps increases sharply and their service life decreases; in LED lamps, the power practically does not depend on the input voltage.
- LED lamps do not require special disposal conditions, as they do not contain mercury, its derivatives and other toxic, harmful or hazardous constituent materials and substances. In all traditional gas-discharge lamps, mercury or its compounds are present.
- In LED lamps, it is possible to reduce the level of luminous flux at night by reducing power consumption by 30-50%, which leads to significant energy savings.
What are the requirements for LED and fluorescent lamps (luminaires) used to organize lighting in public spaces.
The most complete answer is contained in the letter of the Head of Rospotrebnadzor G.G. Onishchenko dated 01.10.2012 No. 01 / 11157-12-32 “On the organization of sanitary supervision over the use of energy-saving light sources”.
The Federal Service for Supervision of Consumer Rights Protection and Human Welfare informs that in accordance with the Federal Law of November 23, 2009 No. 261-FZ “On Energy Saving and Energy Efficiency and on Amendments to Certain Legislative Acts of the Russian Federation” from January 1 2011, electric incandescent lamps with a power of one hundred watts or more, which can be used in alternating current circuits for lighting purposes, are not allowed for circulation in the Russian Federation. From January 1, 2011, it is not allowed to place orders for the supply of electric incandescent lamps for state or municipal needs, which can be used in alternating current circuits for lighting purposes.
For the organization of general and local artificial lighting in public spaces, it is recommended to use fluorescent and LED lamps as light sources.
On the Russian market there are models of compact fluorescent lamps (hereinafter referred to as CFLs) from more than 40 manufacturers, which differ in power, light characteristics, shapes, service life, size, and price. The volume of consumption of energy-saving lamps in the Russian Federation is constantly increasing. Imports of compact fluorescent lamps reached 107 million in 2011. In connection with the development of modern energy-efficient light sources, including LEDs and lighting devices based on them, it is necessary to ensure hygienic lighting standards in institutions of general and primary vocational education and in children's health organizations.
The most pressing issue in the use of CFLs is still the problem of their disposal and safety of use. Each such lamp can contain up to 3-5 mg of mercury, which is in the state of aggregation in the form of vapors. The danger is the careless handling of used lamps. A broken or damaged lamp bulb releases mercury vapours, which can cause severe poisoning.
Currently, lamps using Amalgam technology are produced in the Russian Federation. As part of such a lamp, mercury is not in its pure form (liquid and / or vapor state), but in the form of an amalgam - a chemical solution of mercury in another metal, i.e. in a solid aggregate state. When the amalgam is heated to 60 C above, mercury vapor is released and participate in the lamp glow process. Such a technological solution excludes the ingress of mercury vapor into a room with room temperature in case of violation of the integrity of the glass flask.
In addition, CFLs are available for sale, made in a silicone circuit over the lamp. The silicone gasket protects the tube and flask, acting as a shock absorber in case of a fall, and limits the spread of mercury.
In order to minimize pollution of enclosed spaces in case of CFL damage, it is recommended to use lamps manufactured using these technologies.
In addition to compact fluorescent lamps, the lighting equipment market of the Russian Federation has been offering LED lighting sources since 2010, which have a number of advantages. LED lamps are economical and have an energy consumption of 80% less than incandescent lamps, have high shock and vibration resistance. LED lamps have no gas filling, they almost do not heat up, their service life can reach up to 100,000 hours. Such lamps do not contain mercury, which makes them safe in terms of environmental pollution.
In order to determine the possibility of using LED lighting and LED lamps of the Research Institute of Hygiene and Health Protection of Children and Adolescents of the RAMS Institution of the Federal State Budgetary Institution "Scientific Center for Children's Health" of the Russian Academy of Medical Sciences with the participation of employees of the State Enterprise "Scientific and Technological Center for Unique Instrumentation of the Russian Academy of Sciences" and the Research Institute of Building Physics of the Russian Academy Architecture and Building Sciences have conducted research on the psychophysiological effects of LED lighting and LED lamps on the human body.
The conducted studies have shown the possibility of using LED lighting and LED lamps in residential and public buildings.
In this regard, educational authorities in the constituent entities of the Russian Federation, legal entities and individual entrepreneurs, educational and children's health organizations, design organizations should be notified of the possibility of ensuring hygienic lighting standards established by SanPiN 2.4.2.2821-10 "Sanitary and epidemiological requirements for conditions and organization of training in educational institutions", SanPiN 2.4.3.1186-03 "Sanitary and epidemiological requirements for the organization of the educational and production process in educational institutions of primary vocational education" and SanPiN 2.2.1 / 2.1.1.1278-03 "Hygienic requirements for natural, artificial and combined lighting of residential and public buildings, in institutions of general and primary vocational education, as well as in children's health institutions, by using LED light sources and lighting devices based on them, subject to a number of conditions. When used in general lighting systems in public buildings and in the educational process, luminaires with LEDs must comply with a number of qualitative and quantitative indicators of lighting.
- The conditional protective angle of the luminaires must be at least 90°. This parameter imposes requirements on the design features of lighting fixtures to limit the glare of LED lamps and is measured with a protractor and square. 2. Overall brightness of luminaires should not exceed 5000 cd/m. Due to the fact that the overall brightness of open LEDs is extremely high, it is impossible to use a luminaire with open LEDs for general lighting of premises. Lighting fixtures must include effective diffusers that reduce the overall brightness to the above values. The specified parameter is measured by a luminance meter.
- The permissible unevenness of the brightness of the outlet of the luminaires Lmax:Lmin should be no more than 5:1. It can be estimated after measurements with a luminance meter as the ratio of the maximum measured brightness to the minimum.
- The color correlated temperature of white light LEDs should not exceed 4000°K. You can estimate the color temperature of the LED source by marking on the base or packaging of the lamp. Color temperature is the temperature of a black body (Planck emitter) at which its radiation has the same color as the radiation of the object in question. It determines the color tone (warm, neutral or cold) of the space illuminated by these sources.
- It is not recommended to use LEDs with a power of more than 0.3 W in lighting installations. The power of the mounted LEDs is indicated in the marking of the lamp located on the base or on the packaging.
The passport data for lamps with LEDs intended for installations of general and local lighting in institutions of general and primary vocational education must contain information on the magnitude of the overall brightness, the unevenness of the brightness along the lamp outlet and the value of the color correlated temperature.
When carrying out supervisory activities, attention of legal entities and individual entrepreneurs should be drawn to the need for timeliness, completeness and reliability of production control over compliance with the requirements for general, local and combined lighting in buildings and premises.
Head G.G. Onishchenko
In connection with the entry into force on February 15, 2013 of the Technical Regulations of the Customs Union "On the safety of low-voltage equipment" (hereinafter TR TS 004/2011), changes are being made in Russia to the procedure for confirming the conformity of lighting products. The article provides a brief overview of national and interstate standards for LED products that have recently been introduced and are under development, as well as information on certification procedures for LED products.
The creation of white LEDs made it possible to use a fundamentally new, energy-efficient light source in lighting systems and served as the beginning of the rapid development of technologies and the production of new generation lighting products. Scientific research conducted by leading companies was aimed at increasing the efficiency of the luminous flux of semiconductor light sources, reducing their cost, and increasing their service life. Since 2005, the first domestic LED lighting systems have appeared. In 2008-2009 serial production of domestic LEDs begins, and competition arises in the Russian market for manufacturers of LED lighting systems. Currently, according to various estimates, more than 90% of the components imported into Russia are used for the production of LED lighting systems. However, the creation of an internal infrastructure for the production of LEDs and lighting products based on them is gradually taking place in Russia. One of the main problems of the Russian LED lighting market is the low quality of products. This is due to the fact that mass production is only being mastered, manufacturing technologies are being worked out, the market is just being formed, the legal framework is being formed, requirements for certification of LED products are being introduced, testing metrological centers are being created and gaining experience. A number of recent events in the field of LED lighting systems in our country inspire optimism.
SUE RM "NIIIS named after A. N. Lodygin", in turn, is actively involved in this process and is carrying out certain work in the LED direction:
- development and production of LED lamps for direct replacement of general purpose incandescent lamps with a power of 25, 40 and 60 W;
- standardization of LED light sources and methods for monitoring their parameters within the framework of the Technical Committee TK 332 "Lighting products" created on the basis of LLC "VNISI" (Moscow), a member of which is SUE RM "NIIIS named after A. N. Lodygin";
- metrological support of tests, testing and measurements of LED products;
- certification of LED products.
LED lamp
In 2012, the SUE RM "NIIIS named after A. N. Lodygin" developed the design and manufacturing technology for a series of energy-saving environmentally friendly LED lamps with white LEDs with a power of 3, 5, 7 W, with an E27 base. In terms of their lighting and overall characteristics, they correspond to general-purpose incandescent lamps with a power of 25, 40 and 60 W and can replace them in household lighting installations. The service life of LED lamps is at least 30 thousand hours (or 10 years). On fig. Figures 1 and 2 show the appearance of the developed LED lamps, Table 1 shows their parameters. At the same time samples of LED lamps with a remote phosphor were manufactured and tested for efficiency. According to the results of measurements, LED lamps with a remote phosphor have an 8-10% higher luminous flux compared to lamps with white LEDs. All work was carried out with the support of the Government of the Republic of Mordovia, the Ministry of Industry, Science and New Technologies of the Republic of Mordovia.

Standards for LED lamps
In 2011, SUE RM "NIIIS named after A. N. Lodygin" developed three standards for LED products:
- GOST R 54814-2011/IEC/TS 62504:2011 LEDs and LED modules for general lighting. Terms and Definitions";
- GOST R IEC 62560-2011 "LED lamps with built-in control device for general lighting for voltages above 50 V. Safety requirements";
- GOST R 54815-2011/IEC/PAS 62612:2009 "LED lamps with built-in control device for general lighting at voltages above 50 V. Operational requirements".
For more information on these standards, see .
The procedure for examination, the release of a typographical version and the introduction of standards lags behind the development of scientific and technological progress in the field of LED technologies. GOSTs adopted in 2011 need to be revised, as changes have already been made to IEC standards, on the basis of which national standards were developed. Update required for:
- GOST R 54814-2011, since a new edition of the IEC 62504 standard was released in July 2012;
- GOST R IEC 62560-2011, since there is a change from October 2012 in the IEC 62560 standard regarding terms and tests;
- GOST R 54815-2011 - change in the IEC 62612 standard of February 2012
In 2012, the SUE RM "NIIIS named after A. N. Lodygin" continued work (final editions) on the development of standards related to LED products:
- GOST R “Electric light sources. Methods for determining light and electrical parameters”;
- GOST R “Electric light sources. Methods for determining spectral and color characteristics”;
- GOST R IEC 62471 "Photobiological safety lamps and lamp systems" (IEC 62471:2006 Photobiological safety lamps and lamp systems (IDT)).
In 2012, the first drafts of the following standards were developed with notification of their placement on the Rosstandart website:
- GOST R IEC 62663-1 “LED lamps with base without control device. Part 1. Safety Requirements”;
- GOST R IEC 62663-2 “LED lamps with base without control device. Part 2. Operational requirements”;
- GOST R IEC 62707-1 “LEDs. Part 1. General requirements for binning and chromaticity grid for white LEDs”;
- GOST R IEC 62717 “LED modules for general lighting. Operational Requirements".
The development of national standards for LED products will allow manufacturers, consumers and other interested organizations to:
- uniformly classify LED light sources;
- provide a unified approach to assessing the quality and safety of manufactured and purchased LED light sources;
- apply objective methods for measuring light, color and electrical parameters, monitoring and predicting service life, etc.
In connection with the adoption of the Technical Regulations of the Customs Union "On the safety of low-voltage equipment" (TR TS 004/2011), approved. By the decision of the Commission of the Customs Union dated August 16, 2011 No. 768, in the territory of three countries (the Russian Federation, the Republic of Belarus, the Republic of Kazakhstan), interstate status standards GOST IEC, GOST IEC, STB IEC, STB IEC are put into effect to confirm compliance. Today, for example, for LED light sources, in addition to national standards, on the territory of the Russian Federation there are interstate standards of the Customs Union:
Many experts, and not only lighting engineers, are wondering about the future demand for standards in the status of GOST R when switching to certification of LED products according to interstate standards. The answer is obvious: the national GOST R status standards will be gradually abolished, as is now happening with standards for other types of lamps. For example, GOST R 53881-2010 “Lamps with built-in ballasts for general lighting. Safety Requirements” by order of Rosstandart dated November 29, 2012 No. 1409 is canceled from January 2014 due to the entry into force of the interstate standard GOST 31999-2012 (IEC 60968:1988) “Lamps with built-in ballasts for general lighting. Safety requirements. General technical conditions".
Measurements and tests
The accredited testing laboratory of SUE RM "NIIIS named after A. N. Lodygin" (registration No. ROSS RU.0001.22ME33) measures electrical and light parameters, colorimetric characteristics and other tests of LED products. Regular comparative tests allowed the specialists of the SUE RM "NIIIS named after A. N. Lodygin" together with LLC "VNISI", FSUE "VNIIOFI", LLC "Archilight", the company "Optogan", CJSC "Svetlana-Optoelectronics" to develop 127 methods for controlling the parameters of LEDs and LED light sources, which were subsequently included in the GOST R projects “Electric light sources. Methods for determining light and electrical parameters”, GOST R “Electrical light sources. Methods for determining spectral and color characteristics. These GOST R projects are currently at the stage of examination.
Specialists of the State Unitary Enterprise RM "NIIIS named after A. N. Lodygin" photometer not only electric LED light sources, they also mastered the measurement of photoluminescent evacuation systems, the main lighting parameter of which is brightness. To evaluate it, in 2012, a Konica Minolta LS-100 luminance meter was purchased, which makes it possible to estimate the brightness value from 1 cd/m2 and higher. This device allows you to measure the brightness of LED lamps and light sources.
Certification of LED Products
On February 15, 2013, TR TS 004/2011 was put into effect, developed in accordance with the Agreement on uniform principles and rules of technical regulation in the Republics of Belarus and Kazakhstan and the Russian Federation dated November 18, 2010 in order to establish a Customs Union in the common customs territory uniform mandatory requirements for application and fulfillment of requirements for low-voltage equipment (LV), ensuring the free movement of LW released for circulation in the common customs territory of the Customs Union.
If other technical regulations of the Customs Union have been adopted for the DO, which establish requirements for it, then the DO must comply with the requirements of these technical regulations of the Customs Union, which apply to it. For example, these include the Technical Regulations of the Customs Union "Electromagnetic compatibility of technical means" (TR TS 020/2011), approved. Decision of the Commission of the Customs Union dated December 9, 2011 No. 879.
NR refers to electrical equipment intended for use at a rated voltage of 50-1000 V (inclusive) AC and 75-1500 V (inclusive) DC.
The list of NO, subject to confirmation of conformity in the form of certification in accordance with TR TS 004/2011, includes lighting equipment and light sources, including LEDs.
Thus, confirmation of conformity (certification) of lighting equipment and light sources in the Customs Union will be carried out in accordance with:
Standards for LED lamps and modules have been listed above. The list of standards from [ , ], which establishes safety requirements for the most common LED lamps:
- STB IEC 60598-1-2008 “Lights. Part 1. General requirements and test methods”;

Registration of a certificate of compliance with the requirements of the technical regulations of the Customs Union is carried out in accordance with the document "Unified form of a certificate of compliance with the requirements of the technical regulations of the Customs Union and the rules for its execution", approved. Decision of the Board of the Eurasian Economic Commission dated December 25, 2012 No. 293. Copies of issued certificates of conformity, if necessary, are made by the applicant on A4 white paper (210 × 297 mm), certified by his signature and seal.
Certificate blanks are printed in the Customs Union member states. At the same time, the typographical number of the form produced in the Republic of Belarus contains the designation "Series BY", in the Republic of Kazakhstan - "Series KZ", in the Russian Federation - "Series RU". Forms are filled in Russian using electronic printers. If necessary, the name of the manufacturer, its location, including the actual address (except for the name of the state), and product information (type, brand, model, product article, etc.) can be indicated using Latin letters. The reverse side of the certificate of conformity can be filled in the language of one of the member states of the Customs Union on a voluntary basis.
Certificates of conformity with the requirements of the technical regulations of the Customs Union are issued by certification bodies included in the Unified Register of Certification Bodies and Testing Laboratories (Centers) of the Customs Union. Tests for certification purposes are carried out by accredited testing laboratories (centers), also included in the Unified Register of the Customs Union.
Market Rules
Lighting equipment is put into circulation on the market if it complies with TR CU 004/2011, as well as other technical regulations of the Customs Union, which apply to it, and provided that it has passed confirmation of compliance with TR CU.
Equipment that meets the requirements of TR CU 004/2011 and has passed confirmation of conformity must be marked with a single mark of product circulation on the market of the Customs Union member states, approved by the Decision of the Commission of the Customs Union dated July 15, 2011 No. 711 (subject to changes approved by the Decision of the Commission of the Customs Union dated September 23, 2011 No. 800) (Fig. 3).
Rice. 3. Image of a single sign of product circulation on the market of the member states of the Customs Union
Lighting equipment, the compliance of which with the requirements of TR CU 004/2011 has not been confirmed, should not be marked with a single sign of product circulation and is not allowed to be put into circulation on the market of the Customs Union. The certificate of conformity for the requirements of the Customs Union will be issued for a period of up to 5 years for mass-produced products; for a batch (single product), the validity period of the certificate of conformity is not established.
When switching to confirmation of compliance with the requirements of TR TS, manufacturers will face some innovations in the procedure and problems, including:
- The need to acquire interstate standards and implement them at enterprises.
- The need to certify LED lighting products, which were not subject to mandatory certification before the entry into force of the TR CU and for which manufacturers received a voluntary certificate (street lamps, spotlights, LED lamps and modules) or sold without a certificate.
- Certification schemes for mass-produced products according to TR CU require an analysis of the state of production or the availability of a certified quality management system, which will lead to an increase in the cost of certification for manufacturers that have not yet had a certified quality management system according to ISO 9000 series standards.
In addition, the tightening of the requirements of Rosaccreditation to certification bodies (CB) and testing laboratories (TL) will also indirectly affect market participants.
In October 2012, new Accreditation Criteria were established, and at present, instead of six criteria for ILs, 94 criteria are presented, and 65 criteria are presented for OS instead of five. The purpose of establishing new criteria is to bring the organization of work of OS and IL closer to the requirements of international standards.
One of the conditions for the inclusion of testing laboratories in the Register of Laboratories of the Customs Union is the status of a laboratory both technically competent and independent, that is, testing laboratories created at manufacturing enterprises and accredited in the GOST R Certification System, if they want to continue their activities, they will have to decide on their legal status.
OS and testing laboratories, which often issued certificates very cheaply without proper testing, will either leave the market or be forced to carry out tests in full, and an increase in the actual labor intensity when testing in these testing laboratories will inevitably lead to an increase in testing costs and may lead to an increase in the cost of certification services.
In conclusion, I would like to emphasize that today the process of introducing LED lighting is taking on a civilized form, that is, it is proceeding systematically, although perhaps not as quickly as we would like. The emergence of standards for LED products will create favorable conditions for the introduction of energy-efficient products based on LEDs into lighting systems. A positive moment is also the domestic development of lamp designs, which is gaining momentum, the work on measuring and evaluating the quality of products and issuing certificates confirming the quality and safety of LED products.
Currently, there are regulations and Federal Laws, both prohibiting and allowing the use of LED light sources for lighting school classrooms. But, in the near future, this conflict may be eliminated.
The use of LEDs is allowed in:
SanPiN 2.4.2.2821-10 "Sanitary and epidemiological requirements for the conditions and organization of education in educational institutions" (as amended on November 24, 2015). In accordance with 7.2.2 of this SanPiN:
“7.2.2. In the classrooms, the general lighting system is provided by ceiling lamps with fluorescent lamps and LEDs. Lighting is provided using lamps according to the color emission spectrum: white, warm white, natural white.
SP 52.13330.2016 "SNiP 23-05-95* Natural and artificial lighting". It was put into effect for voluntary use from May 8, 2017 by Order of the Ministry of Construction of the Russian Federation of November 7, 2016 N 777 / pr. In this fundamental regulatory document, there is no prohibition on the use of LED light sources for school lighting.
The use of LEDs is prohibited:
SP 251.1325800.2016“Buildings of educational organizations. Design Rules". This set of rules allows the use of LED fixtures only with remote phosphor.
SP 256.132500.2016 Electrical installations of residential and public buildings. Rules for design and installation. In this code of practice, LED light sources for lighting schools are prohibited.
Currently, these sets of rules are being amended to bring their requirements for lighting schools in line with the requirements of SP 52.13330.2016.
SanPiN 2.2.1/2.1.1.1278-03"Hygienic requirements for natural, artificial and combined lighting of residential and public buildings." In accordance with 3.1.5 (5th paragraph) of this SanPiN: "In institutions of preschool, school and vocational education, as well as in the main functional premises of medical institutions, discharge lamps and incandescent lamps should be used."
In accordance with 1.4 and 1.6 SanPiN 2.2.1/2.1.1.1278-03:
“1.4. Compliance with the requirements of these sanitary rules is mandatory for citizens, individual entrepreneurs and legal entities involved in the design, construction, reconstruction and operation of buildings.
1.6. State sanitary and epidemiological supervision over the implementation of these sanitary rules is carried out by institutions of the state sanitary and epidemiological service of the Russian Federation.
Thus, the State Sanitary and Epidemiological Supervision has the right to prohibit the conduct of the educational process in general educational institutions in which LED lamps are installed, despite the fact that there are permits and regulations.
Currently, some schools have installed LED lamps, despite the existing prohibitions. In the case of using LED lamps in schools, it will not be superfluous to coordinate the adopted technical solutions with the regional department of the State Sanitary and Epidemiological Supervision, so that their representatives give official permission for non-compliance with the requirements of SanPiN 2.2.1 / 2.1.1.1278-03.
SP 52.13330.2011"SNiP 23-05-95* Natural and artificial lighting".
The Order of the Ministry of Construction of the Russian Federation of February 10, 2017 N 86 / pr “On Amendments to Certain Orders of the Ministry of Construction and Housing and Communal Services of the Russian Federation” states:
“Clause 2 of the order of the Ministry of Construction of Russia dated November 7, 2016 N 777 / pr “On the approval of SP 52.13330 “SNiP 23-05-95 * Natural and artificial lighting” shall be stated as follows:
"2. Since the entry into force of SP 52.13330 "SNiP 23-05-95* Natural and artificial lighting" to recognize as not applicable SP 52.13330.2011 "SNiP 23-05-95* Natural and artificial lighting", approved by order of the Ministry of Regional Development Russian Federation dated December 27, 2010 N 783, with the exception of paragraphs of SP 52.13330.2011"SNiP 23-05-95 * Natural and artificial lighting", included in the List of national standards and codes of practice (parts of such standards and codes of practice), as a result of the application of which on a mandatory basis compliance with the requirements of the Federal Law "Technical Regulations on the Safety of Buildings and Structures", approved by Decree of the Government of the Russian Federation of December 26, 2014 N 1521 (hereinafter - the List), is ensured until the relevant changes are made to the List."
Thus, in the said List, there is still 7.18 of the set of rules SP 52.13330.2011, according to which:
“7.18 The choice of light sources according to color characteristics for public, residential and auxiliary premises should be made on the basis of Appendix I, taking into account 7.3 and 7.4.
in preschool institutions, school and vocational education, as well as in the main functional premises of medical institutions, fluorescent (including compact) lamps and halogen incandescent lamps should be used.
In other public spaces, the use of halogen incandescent lamps for general lighting is only allowed to meet architectural and artistic requirements.”.
That is, until the replacement of the set of rules SP 52.13330.2011 with SP 52.13330.2016 in the specified List, the use of LED lamps in schools is a direct violation of the Federal Law "Technical Regulations on the Safety of Buildings and Structures", adopted by the State Duma on December 23, 2009 and approved by the Federation Council December 25, 2009.
In the set of rules SP 52.13330.2016, which entered into force on May 8, 2017, LED lamps in schools are not prohibited. But in 7.3.1 there is a ban on the use of LEDs in preschool educational institutions and in the main functional premises of medical and preventive institutions.
Given that the set of rules SP 52.13330.2016 will eventually replace the set of rules SP 52.13330.2011 in the List of national standards and sets of rules (parts of such standards and sets of rules), as a result of the application of which on mandatory basis compliance with the requirements of the Federal Law "Technical Regulations on the Safety of Buildings and Structures" is ensured, then in the coming years the use of LED lamps in kindergartens and in the main functional premises of medical and preventive institutions will be prohibited at the level of the Federal Law.
Defending the possibility of using LEDs in schools, they often refer to Decree of the Government of the Russian Federation No.
There is no ban on the use of fluorescent lamps in educational institutions (schools) in Government Decree No. 898 of August 28, 2015.
According to this Decree (paragraph 4 of paragraph g)): “a ban on the purchase of luminaires for double-ended fluorescent lamps with a G13 base, except for cases when lighting in accordance with sanitary rules and regulations that establish requirements for artificial and mixed lighting cannot be applied LED Light Sources.
In accordance with the sanitary rules and norms of SanPiN 2.2.1 / 2.1.1.1278-03, as noted above, for institutions of school and vocational education, as well as in the main functional premises of medical institutions, discharge lamps and incandescent lamps should be used.
The Government Decree No. 898 of August 28, 2015 contains a ban on:
Acquisition of double-ended fluorescent lamps with a diameter of 26-38 mm with a calcium halophosphate phosphor and a color rendering index of less than 80 with a G13 base;
Prohibition on the purchase of non-electronic ballasts for tubular fluorescent lamps;
Prohibition on the purchase of fixtures for arc mercury fluorescent lamps.
Conclusion
Problems with the use of LEDs in schools, apparently, will begin after the removal of restrictions on their use in regulatory documents. In essence, soon the set of rules SP 52.13330.2011 will be replaced in the List of mandatory documents by SP 52.13330.2016. And only SanPiN 2.2.1 / 2.1.1.1278-03 will be a prohibitive document. But in the near future, appropriate changes may be made to it.
Presumably, this SanPiN will include specific requirements for LED lighting in terms of color temperature, maximum LED power, etc. And many existing LED lighting installations in schools may not meet these requirements.
It is worth paying attention to the standard of the Association of Manufacturers of LEDs and Systems based on them STO.69159079-01-2017 “LED lamps. Requirements for technical and operational parameters. This standard sets out many of the requirements for LED luminaires for schools and it is highly desirable not to use luminaires with parameters inferior to the recommendations of this document.

Also, it would seem that there are no clear instructions on the mandatory introduction of LED light sources in educational institutions and in the program "On Energy Saving and Increasing Energy Efficiency", approved in 2010. You can verify this yourself:
https://docviewer.yandex.ru/?url=http%3A%2F%2Fwww.minenergo.gov.ru%2Fupload%2Fdocs%2Fee%2Fb612746a17...
Well, since there seem to be no clear regulatory documents, the LED industry immediately began to aggressively promote all its products to schools and universities, kindergartens and boarding schools, praising and proving economy and energy efficiency in every way.
Some of the leaders of educational institutions are in no hurry to replace lighting with LEDs, some are waiting for clear explanations or orders from government agencies, and some are already forced to change lamps due to the expired life of the current lighting, and often without a clear and transparent system of requirements, puts in their institutions what in fact does not correspond even to the currently approved standards.
How to determine which LED lamps are allowed to be installed in educational institutions?
Let's turn on the logic and read the current sanitary rules and regulations more thoughtfully in order to predict changes that will more correctly regulate the use of LED lamps in educational institutions when the Ministry of Health completes all work on the next amendments to the current SanPiN.
What specific types of current LED luminaires most closely match the current requirements for lighting schools and kindergartens, as well as other educational institutions?
To do this, it is enough to analyze in more detail each subparagraph of the corresponding SanPin.
A number of today's LED lighting manufacturers are limited to this first point:
7.2.1. In all premises of a general educational institution, levels of artificial illumination are provided in accordance with the hygienic requirements for natural, artificial, combined lighting of residential and public buildings.
That is, they receive a general TS certificate, which combines the previously used Certificate of Conformity and the Hygienic Certificate. And with this document they are trying to prove to school principals that, they say, everything is in accordance with the norms.
But in fact, not all lamps are actually suitable for lighting in classrooms and auditoriums.
To do this, it is enough to carefully study the other points of SanPin.
For example, literally the following paragraph should be parsed with the utmost care:
7.2.2. In the classrooms, the general lighting system is provided by ceiling lights. Fluorescent lighting is provided using lamps according to the color emission spectrum: white, warm white, natural white.
Luminaires used for artificial lighting of classrooms should provide a favorable distribution of brightness in the field of view, which is limited by the discomfort index (Mt). The indicator of discomfort of the lighting installation of general lighting for any workplace in the class should not exceed 40 units.
1) Spectrum of color emission this paragraph is very vague. It’s easy to guess what this is connected with at the moment - most of the current SanPiN inherited the text from the earlier version, since there was no more specific classification for fluorescent lamps.
Now, with the advent of LED analogues and the variety of their color reproduction, it is worth noting that in this case, LED lamps with light color from 2700K to 5000K should be used. It is this range of color temperature that is commonly referred to as the values warm white(2700K-3500K), White(4000K-5000K), natural white(3500K-4500K).
What is it connected with?
This range is closest to natural light in the daytime, and is comfortably perceived by the eye.
If a softer and more comfortable warm white (2700K-3500K) is more recommended for installation in preschool institutions, then all others (from 3500K to 5000K) are for installation in school classrooms and university classrooms.
This is directly related to the peculiarities of human perception - the warm white color of the glow has a calming, pacifying effect on us, it is associated with coziness and comfort, and natural white increases efficiency, perception, and tones brain activity.
It should be noted that there is another type - cold white(over 5000K). This glow is the brightest and high-contrast, but increases fatigue and, with prolonged exposure during the day, acts depressingly on a person. So lamps with color over 5000K are not recommended for educational institutions.
2) Also a very important parameter - Ra color rendering index. It is not directly mentioned in SanPiN itself (since this indirectly refers to clause 7.2.1), but there is a clear gradation of premises according to the characteristics of visual work. It is mentioned in a rather old, but valid document SNiP 23-05-95, to which this SanPiN refers:
http://www.docload.ru/Basesdoc/1/1898/#i772208
And, according to the table from this document, lamps in the premises of educational institutions must have an index of Ra> 80.
3) Another extremely important detail - indicator of discomfort Mt. This is a criterion for evaluating uncomfortable glare, which causes discomfort with an uneven distribution of brightness in the field of view. The indicator of discomfort (M) characterizes the degree of inconvenience or tension in the presence of point sources of increased brightness in the field of view.
That is why all lighting devices (or light sources) in rooms for long-term stay of people have a matte protective shell. In the case of incandescent lamps, these are frosted shades, in the case of fluorescent lamps, directly the bulbs of the lamps themselves.
Thus, in order to meet the indicated indicator, all LED light sources in the premises of educational institutions must also be hidden behind a matte diffuser, since the point brightness of the LEDs is not comfortably leveled by other types of diffusers (prism, microprism, crushed ice, etc.).
4) Indirectly, the indicator of discomfort should also include ripple factor. It characterizes the relative depth of the illumination pulsation (in%) at a given point in the room when the lamps are powered from the AC mains. Uncontrolled pulsation of illumination leads to an increased risk of injury when working with moving and, in particular, rotating objects, as well as visual fatigue. In the norms of Russia for most visual works it is established Kp value no more than 20.
As for LED light sources, they all operate on DC voltage, and the ripple factor of LED lamps, as a rule, is related to how well the driver (luminaire power supply) converts AC to DC. In the vast majority of cases, pulsation factor of LED lamps<5% . Therefore, this criterion can practically be neglected when selecting lamps for educational institutions.
So, let's sum up.
According to the current regulatory documents, in preschool, general education and higher educational institutions, LED lamps should be used, which, in addition to the necessary and sufficient values total luminous flux, power, degree of protection, dimensions and overhead installation method, correspond to the following parameters:
1) Light color: 2700K-3500K - for preschool institutions, 3500-5000K - for general education and higher educational institutions.
2) Diffuser type: opal, matte or milky white
3) Color rendering index Ra > 80
4) Ripple factor< 5%
Often, when choosing a lamp, the question of the material of the diffuser also arises. In the normative documentation there are no instructions for the material of the diffuser for luminaires installed inside the premises of educational institutions, so the choice of diffuser material is left to the discretion of the management of the educational institution.
Different materials have different light transmission and wear resistance, but In most cases when the question rests on the cost of the product, the choice falls on cheaper materials, such as lighting polystyrene or polyacrylic(PMMA). In the cases when needed the strength of the diffuser to mechanical damage - apply more expensive polycarbonate.
