Through the implementation of the national semiconductor lighting project, the development speed of application fields such as LED lighting is accelerating, and there has been a situation of close cooperation between interdisciplinary, inter-disciplinary and various industries. At the same time, the country's support for LED lighting and the huge market demand for such products have made China's LED industry face a rare historical opportunity.
We also noticed that although LED lighting has achieved some achievements in these fields, the LED lighting industry has not yet unified national industry standards, which is becoming a major obstacle to the development of China's LED industry. Under this circumstance, Guangdong Province took the lead in the implementation of the "Guangdong Province LED Street Light Local Standards" in July, which is an important step for Guangdong and even to solve these problems in a larger area, with far-reaching guiding role and Realistic meaning.
First of all, it is conducive to promoting the research and formulation of semiconductor lighting standards in China. Semiconductor lighting has developed rapidly in recent years. It has entered the functional lighting fields such as roads, tunnels, industrial and commercial lighting from special lighting fields such as display and indication. There have been many types of products, many specifications, uneven product quality and different energy-saving effects. Larger issues. After implementing the national semiconductor lighting project, the Ministry of Science and Technology has been paying close attention to the establishment of the semiconductor lighting standard system, the research of the testing method and the testing platform. The relevant departments have established a semiconductor lighting standardization steering committee to coordinate the standardization work at the national level and entrust The National Semiconductor Lighting Engineering R&D and Industry Alliance has established a standardization and coordination promotion working group, which has achieved the cooperation of major domestic LED standardization organizations and testing organizations. The committee organized and drafted relevant technical specifications, guided technological innovation, and made preliminary work for the scientific and rational formulation of standards. In particular, in response to the demonstration of the Ten Cities and Ten Thousand Pilots initiated by the Ministry of Science and Technology, the committee also drafted the "Technical Specifications for LED Road Lighting Products for the Pilot Demonstration Project of Semiconductor Lighting", "LED Tunnel Lights" and "Supervisory Inspection and Inspection of LED Road and Tunnel Lighting Products". Installation and Acceptance Regulations (Draft for Comment), and began to prepare technical specifications for LED indoor downlights and spotlights. The introduction of "Guangdong Province LED Street Lamp Local Standards" will further promote the establishment of China's semiconductor lighting standard system and play an important role in the application demonstration of local LED street lamps.
Secondly, it is conducive to standardizing the LED lighting market in Guangdong and guiding the development of the LED lighting industry. Guangdong has already formed a certain scale of LED industry clusters. Although it is in a leading position in China, due to the insufficiency of the overall development of the industry and the lack of uniform industry standards, many enterprises with insufficient strength have also become popular, which has intensified the disorder of market competition. The phenomenon of product homogenization is serious. In the long run, it will eventually affect the overall market order and development prospects. The implementation of "Guangdong Province LED Street Lamp Local Standards", through the definition, classification, model and naming of LED street lamps, technical requirements, test methods, inspection rules and requirements for marking, packaging, transportation and storage, so that the production of LED lighting enterprises and Market behavior has a behavioral norm that is conducive to the continued healthy development of the Guangdong LED lighting market.
Once again, it is conducive to the promotion and popularization of Guangdong LED lighting products and the cultivation of leading enterprises. At present, with the encouragement and support of national policies, Guangdong is increasing the promotion and popularization of this new technology product through the development of LED lighting application projects such as ten cities and thousands of miles. The implementation of this standard has set clear requirements for the selection of lamps for these application projects. With the continuous promotion of LED street lamps, the quality and level of these application projects will be effectively guaranteed. At the same time, in the process of promotion, the state will filter some vulnerable enterprises whose products are unable to meet the standards, have limited operating strength, lack of technology accumulation, and are not strong in market vitality, so that excellent LED lighting enterprises will be further strengthened.
Finally, it is conducive to play a demonstration role and actively promote the development and standardization of the LED lighting industry in other parts of the country. As the earliest province in China to introduce local standards for LED street lamps, Guangdong LED lighting industry is full of vitality. While embodying the advantages of Guangdong policy, the standard also shows that Guangdong's promotion of LED street lighting technology and experience is relatively mature. Under the situation that the application of popularized LED has become an inevitable trend, it has the demonstration significance of the first-in-first-trial test in other parts of the country. At the same time, the implementation of the standard will also accelerate the development of LED national standard development process, and ultimately help to achieve the overall development and leapfrogging of China's LED lighting industry.
