"Guangdong LED lights local standards," put in place nearly half a year, the number of firms accounting for a quarter of LED intensity of the Pearl River Delta region, the standard to play an increasingly important role. Currently, the development of LED lighting industry has become a hot topic: the "Long-term Scientific and Technological Development Plan", LED lights and other semiconductor lighting products are clearly included in the "priority areas and priority themes", and proposed to "focus on Energy efficient, long life semiconductor lighting products "; National Development and Reform Commission, Ministry of Industry and other ministries jointly issued a 6" semiconductor lighting energy industry views "; Ministry of Science and also officially launched the" city of ten thousand ten "semiconductor lighting project; Guangdong Province, "a thousand miles of thousands of" LED street lamp demonstration project is rapidly advancing.
Good development in this situation, "Guangdong LED lights local standards," the introduction and implementation, can be described as ideally the timing, location, and both realize the development of the industry, market competition, product quality specifications, but also further promote the standards of the LED lamps in the application of these projects, and will play through the LED industry market in Guangdong and the guiding role of norms will influence gradually expanded to other regions or even across the country, and thus more positive industry market boost.
To this end, the author interviewed Graduate School of Tsinghua University, Shenzhen Semiconductor Lighting Lab Professor Qian Keyuan, chairman of China Association of Lighting Chen Yansheng, the National Electric Light Source Quality Supervision and Inspection Center (Shanghai) deputy director of the Yuan Qi, Zhao Jian, vice chairman of China Illuminating Engineering Society Standardization Institute of Peace Research Center of Guangdong Province Huang Jianping, Xu Chen and other experts and scholars on them from different angles, "Guangdong Province, local standard LED lamps," were interpretation.
As the state encourages the development of LED industry to promote the application of LED products, increasing emphasis on the lack of regional and national standards for LED products, is a constraint to the industry, the rapid and standardized development of an important factor. LED as the most important industrial base and one of the key application areas of Guangdong Province, with LED applications in the exploration and practice, was officially implemented on July 1 of the "Guangdong Province, local standard LED lamps," became the first developed local standards and implementation of LED lights provinces, the Guangdong Province in the norms that guide the development of LED industry and improve the content of LED lamp technology, product quality, comprehensive rule-based competitiveness, but also in promoting the healthy and rapid development of LED lighting industry with a landmark significance.
Interpretation One: Standard macro direction and guidance to both micro-
The standard formulation was officially launched last June by the Quality and Technical Supervision of Guangdong Province and other departments to determine the main drafting units of Dongguan Kingsun Optoelectronic Co., Ltd., Dongguan City, Tsinghua University and the quality supervision and inspection by measuring, by leading enterprises, institutions of higher learning, quality supervision agencies, trade associations and other experts in the drafting group established a standard to LED lights in the field of packaging and application of technical requirements, the important performance indicators for testing repeated study and discussion. For light efficiency, light failure, life, temperature and other data requirements, but also with reference to the Solid State Lighting Industry Alliance R & D and related documents issued by the Guangdong Provincial requirements and the practical application of LED street light industry enterprises Kingsun test and practice results so that the macro and micro guide guidelines adequately highlighted and improved.
Second Reading: LED lights smoke and mirrors what is no longer
"Guangdong LED lights local standards," the practice, so what is the LED lights, LED lights and other performance requirements is no longer a smoke and mirrors. According to Guangdong Provincial Institute of Standardization Research Center, Huang Jianping introduction, the standard applies to the following DC power supply 250V or 1000V ac-powered road, street, tunnel lighting and other outdoor public places, lighting LED lamps, LED lamps are given on a "one- kinds of requirements from the standard shell lamps, LED modules, LED modules control devices, optical components, mechanical parts and other components of the composite lighting "is defined, and the LED lights on the LED module related, LED heat sink, the initial value, the average correlated color temperature, the average color rendering index, rated maximum temperature is explained and clear. Meanwhile, the full total of the twelve chapters, also identified the classification of LED lights, model and name, the technical requirements, test methods, inspection rules and signs, packaging, transport and storage requirements. "Whether it is the content structure, or hierarchy level, the standards have reached a certain height, the guide and regulate the role of taking a step forward in the short term can be revealed."
Interpretation of Three: General and specific technical requirements for the quality of strict security
Street to the general impression, nothing more than illuminate the road at night and the surrounding environment only, LED lamp, as new scientific and technological products, the technical requirements of what the world demands on the need to have? "Guangdong Province, local standard LED lamps," one of the main drafters, Graduate School of Tsinghua University, Shenzhen Semiconductor Lighting Lab Professor Qian Keyuan said that in strengthening the basis of general technical requirements, the standard LED lights also conducted a special technical requirements. It is understood, LED lights of the general technical requirements, including street surfaces, surface coating, welding parts, use of safety and electromagnetic compatibility, the special technical requirements are more extensive and comprehensive. LED lights such as requiring not less than the rated average life of 30,000 hours, rated tc value should not exceed the maximum temperature 58 ℃, LED tube lights in all the biggest heat sink temperature should not exceed 65 ℃, the actual consumption of power and the rated power consumption difference should not exceed 10%, LED lamps light bulbs when the lights go out or adjust the beam shape and surface uniformity of illumination and so should not change significantly.
Yuan pointed out that the money can be very worthwhile to note that this standard is also the main parameters of LED lights were clear. It is the initial light efficiency LED lights divided into 4 grades, to determine the average correlated color temperature and the applied area of road. At the same time, requiring an average color rendering index of not less than 65,2000 hours of luminous flux maintenance ratio of not less than 98%, 5,000 hours of luminous flux maintenance factor of not less than 97%, spot shape is determined to be rectangular, circular and elliptical spots. Combination of general and special technical requirements, the implementation details of these standards have become stricter to ensure that the key to good quality LED lights.
Interpretation of Four: standard test methods for products of concern
In my interview, one of the drafting standard master, LED lighting Kingsun leading enterprises in the technology department official also said it would complete the product specification test methods included in the "Guangdong Province, local standard LED lamps", is the standard widely important reason for concern. For example, in light failure and life experiments, standard LED lamp aging method specific requirements: Requires the experiment in the absence of forced ventilation, temperature control at 20 ℃ -30 ℃ in the environments, lighting set up by the normal installation posture to the nominal Rated voltage power to full power to work. Lamp aging experiments, the number of samples less than 3 units per 24 hours in closed less than 2 times, each time the closing time should be 25-35 minutes, each interval should be at least 30 minutes. Lamps in the process, such as any failure, burn, are unqualified. Meanwhile, the Standard also identified failure and lifetime measurement of light projection method, the maximum temperature, maximum heat sink temperature, the average color temperature and the average color rendering index, lamps and lamps with luminous efficiency of light curve and so content, so the LED lights on the Pearl River Delta Enterprise optimize product quality, enhance the comprehensive competitiveness of more and more obvious, but also by many in the industry full recognition and praise of enterprises.
According to Wang, as is currently the only LED lights local standards, "Guangdong LED lights local standards" also lists the special chapter on the LED lights of the factory inspection, type testing, marking, packaging, transport and storage unified clear in improving the quality of the current market cohabitation LED lights, numerous different styles, lack of competition, the status of norms has been and is playing an increasingly important role.
For the "Guangdong Province, local standard LED lamps," the introduction and implementation of industry experts evaluate how? "In the past there is no industry standard, what is produced, how production and products to what technical requirements are not clearly defined, the basic rely on their own initiative. Standard The introduction of increased barriers to entry, it must eliminate a number of non-compliant enterprises and promote the development of a number of competitive enterprises, which for the healthy development of great significance to promoting the industry. "chairman of China Association of Lighting Chen Yansheng said the standard for domestic LED lighting, is a not a small revolution, will advance into the LED industry, standardization of commissioning period, lead the industry by the disorder, non-standard conditions, to order, a standard state transition. Illuminating Engineering Society of China, said Zhao Jianping, vice president, LED lighting industry has become a focus of the current industry increasingly fierce market competition, the implementation of this standard will help to consolidate the basis of the Pearl River Delta LED lighting industry, enhance the reliability of LED light source to improve the quality of industry standards, and promote the healthy development of the market. National Electric Light Source Quality Supervision and Inspection Center (Shanghai) Yuan Qi, deputy director of the view that, with the further implementation of the standard, its influence will be comprehensive, not only the role of LED lighting industry in the PRD standards and guidance, will other parts of the country form a positive example and influence.

"Guangdong LED lights local standards" to guide a model far-reaching
Solid State Lighting Industry Alliance R & D and Jun Nguyen, Vice Secretary General
Guangdong is China's most important base of the LED industry, in recent years in response to the national call to promote the popularization and application of LED lighting, etc., has been in the country. Guangdong has led the implementation of the LED lights local standards, I think there are four important role.
First of all, help to promote China's semiconductor lighting standards for research and development work. Special lighting, semiconductor lighting from the field, began to enter the roads, tunnels and other functions of the lighting field, there have been many kinds of products, specifications, and other issues of varying quality. Can not meet the standards of work and other requirements of the rapid development of industry, which is the international common problems. Guangdong, the introduction of LED lights local standards, will further promote China's semiconductor lighting standard system for local application and demonstration of work to play an important role.
Secondly, it helps to standardize the LED lighting market in Guangdong, and guide the development of LED lighting industry. Guangdong had already formed a certain scale LED industry cluster, although in a leading position, but due to the overall development of the industry is not mature enough and lack of uniform industry standards, long run, will affect the whole market order and development prospects. "Guangdong LED lights local standards," the implementation of the LED lamps through a clear definition, classification, models and names, technical requirements, test methods, inspection rules and signs, packaging, transport and storage requirements, so that LED lighting in the production and market behavior of a "code of conduct" is conducive to LED lighting market in Guangdong, the sustained and healthy development.
Again, is conducive to the promotion of Guangdong popularity of LED lighting products and cultivate advantages of leading enterprises. At present, national policy to encourage and support, Guangdong is through the "city of ten thousand ten," "a thousand miles of thousands" and other LED lighting application engineering, increase the popularity of the new efforts to promote science and technology products. The standard after the implementation of projects for these applications put forward a clear choice of lighting and other indicators of performance requirements, compliance with the continuous promotion of LED lights will make the quality and level of application engineering are effectively guaranteed. Meanwhile, in the process, some products will not compliance, management strength is limited, lack of technology accumulation, weak market activity is not strong filtering companies, the objective of leading enterprises play a dominant role in training, but also conducive to good LED lighting brands further enlarge and strengthen.
Finally, the beneficial role model for other regions of the LED lighting industry and actively promote the formation of standardization. As the first industry standard for the introduction of LED lights provinces, through which standards to guide the role of the gradually emerging LED lighting industry in Guangdong is full of vitality, the standards reflect the policy advantages of Guangdong, while that of Guangdong to promote technology and LED lights relatively mature experience in the application of LED has become an inevitable trend of universal situation, which other parts of the country has a "pilot" demonstration significance. Other areas will also form a useful inspiration, drive the development of industry standards consistent with local characteristics, and ultimately to promote LED lighting industry in China and across the overall development.
Promote the development of advanced LED industry standard
Institute of Standardization Research Center of Guangdong Province Huang Jianping Xu Chen
"Guangdong LED lights local standards," the introduction of LED lighting for the specification market in Guangdong, and promote technological progress and industrial LED lighting, and healthy development of positive significance. But this is only the beginning, how to continue to promote the effective implementation and improvement of the standard is still very arduous task, requiring a multidimensional measures to ensure the implementation of the standards are implemented.
First, you need to give policy support to government departments at all levels. In the process of implementation of standards, government support, guidance and organization and coordination role is very important, especially in the technology required to implement the standard R & D, technological innovation, etc., require the government, including LED package, application, chip development and other support in thermal, optical, drive, etc. Standardization of LED lighting as spending to improve the implementation of the standards initiative.
Second, the need for LED lighting, the active cooperation of the enterprises. The one hand, enterprises in the production process should be able to conscientiously implement the existing standards at all levels, on the other hand but also in quality management, management level, testing tools and methods to increase their own investment, the quality and standard of its products to work with supporting existing standards.
Again, you need to quickly establish a complete, fair and scientific evaluation system testing. Testing standards as LED lighting products, systems far can not meet the requirements of LED industry, it is imperative to establish and improve a comprehensive, fair and scientific evaluation system for detection of LED lighting. Currently under the guidance of the government's need to establish the appropriate third-party testing organizations LED lighting, the use, development of LED characteristics consistent with test equipment, create a test system that allows both an objective standard reflects the level of technology of LED lighting, LED lighting fast in China adapt to the development, but also consistent with international standards.
We also recognize that any implementation of a standard has been refined and improved the process. And development of speed over time, before the national standard in Guangdong LED lights set local standards, taking a step forward also need to be refined and improved. Through our joint efforts to constantly upgrade the level of the final promotion of standards, and promote the overall development of the Guangdong LED industry, the level of improvement.
