End of year inventory: Interpretation of "local standard of Guangdong LED street lamp"

Guangdong province LED street lamp local standard has been implemented for nearly half a year, the number of LED enterprises accounted for 1/4 of the country's Pearl River Delta region, the role of the standard is becoming more and more important. At present, the development of LED lighting industry has become a hot topic in the "national long-term science and technology development plan", LED lamps and other semiconductor lighting products are explicitly included in the "key areas and priority themes", and proposed to "focus on energy efficient, long-life semiconductor lighting products", the National Development and Reform Commission; Ministry and other 6 ministries jointly issued the "opinions" of the development of semiconductor lighting industry; Ministry of science and technology also officially launched the "ten city lights" semiconductor lighting engineering; Guangdong province Trinidad one hundred thousand LED street lamp demonstration project is rapidly advancing.

In front of this good development situation, "Guangdong province LED street local standards" promulgated and implemented, as well as being the climatic and geographical conditions, not only to achieve the development of the industry, market competition and product quality standard, and can further promote the application of LED lighting standards in these projects, at the same time through the play of the Guangdong LED industry market norms and guiding role, will influence gradually expanded to other areas and even the country, and thus have a positive role in promoting greater industrial market.

To this end, I interviewed the Shenzhen Graduate School of Tsinghua University Professor Yuan money semiconductor lighting laboratory, Chinese lighting appliance association director Chen Yansheng, the national electric light source quality supervision and Inspection Center (Shanghai) Yu Anqi, deputy director of research center of Research Institute deputy director general Zhao Jianping and China Institute of lighting standards of Guangdong province Huang Jianping, Xu Chen and other experts, they from the different angle to the Guangdong province "LED Street" the local standard for the interpretation.

High power LED lighting project of Guangdong Science Center

With the country to encourage the development of LED industry, promote the growing importance of LED product applications, the lack of regional and even national LED product standards, is becoming an important factor restricting the rapid development of the industry, standardized development. Guangdong province is one of the most important industrial base LED and key application areas of our country, combining with the practice in the application areas of LED, on July 1st the formal implementation of the "Guangdong province" the local standard of LED street, became the first to formulate and implement local standard LED lamp Province, Guangdong LED industry development and guide to improve the LED lamp in the specification, technical content, product quality, comprehensive competitiveness is rule-based, to promote the healthy and rapid development of LED lighting industry has the sense of milepost type.

Interpretation of the standard macro guidelines and micro guiding role

The standard setting work officially started in June last year, by the Guangdong Provincial Bureau of quality and technical supervision departments to determine the main drafting unit is Dongguan KingSun Au Optronics Co, Tsinghua University and Dongguan Municipal Quality Supervision and testing of the measurement, and by leading enterprises, universities, Industry Association of quality supervision institutions, experts and other established standards drafting group, LED lamp package and application in the field of technical requirements, performance, testing indexes were repeatedly studied and discussed. The relevant data of light efficiency, light attenuation, life, temperature and other requirements, also referring to the related documents, the national semiconductor lighting engineering research and Industry Alliance released in Guangdong province LED lamp application requirements and industry leading enterprises KingSun test and practical results, the macro and micro guidance to fully highlight and perfect.

Reading two: LED street lamp is what no smoke and mirrors

"The implementation of Guangdong province LED street local standards", which is what LED lights, LED lights and other performance requirements is not. According to the research center of Guangdong Provincial Institute of standards for LED street lamp Huang Jianping introduction, this standard applies to 250V DC power supply or 1000V AC power supply, road tunnel, street lighting and other outdoor lighting in public places, the LED lamp is given by a "standard for the lamp shell, LED module, LED module control device, optical components, mechanical parts and other components of the composite lighting" definition, the LED module, LED heat associated with LED lamp sink, initial value, average temperature, average temperature, maximum rated color index were explained and clear. At the same time, the full text of a total of twelve chapters, but also to determine the LED street lamp classification, model and naming, technical requirements, test methods, inspection rules and signs, packaging, transportation and storage requirements. Whether it is the content structure, or the level of the level, this standard has reached a certain height, the role of its guidance and norms in the short term will be able to get a step closer".

Interpretation three: general and special technical requirements strict quality assurance

Street to the general impression, it is in the night to illuminate the road and the surrounding environment. As a new technology, LED lamp products, in need of technical requirements have what requirements? "Guangdong province LED street local standard" main one of the drafters of the Shenzhen Graduate School of Tsinghua University, semiconductor lighting laboratory money Yuan said, in strengthen the general technical requirements on the standard of LED lamp of the special technical requirements. It is understood that the general technical requirements of the LED street lamp, including the surface, the surface of the spray parts, welding parts, the use of safety and electromagnetic compatibility, special technical requirements are more extensive and comprehensive. If the requirements of LED lamp rated average life should not be less than 30000 hours, the maximum rated temperature Tc value should not exceed 58 degrees, the maximum heat lamps within each LED tube sink temperature should not exceed 65 degrees, the actual power consumption and the rated power consumption difference should not be more than 10%, light
