LED lighting "issuing", go in a standardized way

Recently, Guangdong Province issued 11 to LED lighting local standards, standardized development of the industry and a step forward. I believe in the last year, there will be a lot of people Tucao LED lighting industry standards deficiencies, disorderly competition, but since this year a standard has emerged, the first is the beginning of January the new formulation of the "embedded LED" lamps Performance requirements of national standards issued, the standard is the first LED lamp performance of our country's national standards then, the local government department or industry organizations have released a series of LED lighting standards, so far, although not perfect, but the industry overall standardization is still on the road.


Guangdong Province issued 58 local standards, involving 11 items of LED lighting
In July this year, the 58 standard by the Guangdong Provincial Quality Supervision Bureau approved the release of the Guangdong province formally implemented, which relates to the LED lighting industry has 11 items, including the standard design for LED lighting elevator lighting by the Jiangmen high tech Zone Jiangmen City Junda Photoelectric Technology Co. Ltd. is responsible for the (No. DB4 4 /T1336-2014), the the standard for the first time in the province and the country to develop.


It is reported that the provisions of the elevator lighting lighting standard value, quality, energy conservation, lighting power supply and distribution index of LED lighting design standard, the rated voltage of 250V DC electric and 1000V alternating current, which can be widely used in the lighting system of passenger elevator and cargo elevator office, commercial and residential real estate, shopping malls, railway stations, subway, airports and other public places.


LED explosion-proof lighting related standards landing
In July, the National Standards Commission launched three LED explosion-proof lamp standard plan, aimed at the development of technical standards, leading the industry in LED, explosion-proof lamp intelligent lighting control, application interface specification and the acceleration detection method in areas such as regulating the market, promote innovation. In the international arena, Zhaga Alliance announced the LED explosion-proof lighting engine interface specification of Book7 and Book8, LED explosion-proof lamp new energy efficiency standards of the European Union was formally implemented in March 2014, the sale of new goods LED explosion-proof lamp are forced to paste the energy label.


4 LED lighting industry standards promulgated


Evaluation of semiconductor lighting technology alliance, Chinese /LED semiconductor lighting industry and union in April released LED double end lamp safety requirements, performance requirements and non directional self ballasted lamp LED specifications, performance requirements of the 4 LED lighting industry standards needs to be. Among them, "general lighting, non directional self ballasted LED lamp specification classification" as an important basic standard of semiconductor lighting industry, has been adopted by the authoritative international standard organization, the International Electrotechnical commission. This classification standard in the world for the first time with the lighting effect of "lumen", instead of the traditional "tile", as a division of LED lamp specifications of the new concept, more reflect the LED lights, high efficiency and energy saving characteristics and advantages.


From September onwards, LED drive power into the 3C compulsory certification category


CNCA certification implementation experience combined with pilot implementation rules, carried out a comprehensive product specific implementation rules for compulsory certification of the revision work, the LED driver into the 3C compulsory certification category, since September 1st.、


In the formulation of standards, Quanzhou LED industry is still lagging behind, this year in June to start work in this area. The day before, standard research institute set up a photoelectric, and the Standards Association of Quanzhou city will begin to develop Quanzhou LED quality standard system.


Deletion of the LED standard has been criticized, but also produces a bad effect for the healthy development of the industry, many industry insiders believe that this is due to the development of LED lighting is not mature enough, in many ways, as the technology gradually improved and stable, the introduction of appropriate standards more appropriate. In this regard, the general manager of Hangzhou Heng paive power company limited Ye Jianbo said: "the LED lamp development time is relatively short, there are technical breakthrough year. Many standards apply this year, not next year. This is also an important reason for the lack of standards. In addition, different enterprise technology is not the same, for the standard of understanding is not the same, this also does not affect the standard of unity."


For the lighting industry standard, Crystal Electronics (Guangzhou) Co., a special assistant to President of Song Dong also shared his views, LED lighting industry - there is no standard, because many in the industry view and practices are not uniform. But since 2007, LED's standards have been slowly programmed and are now being followed in the LED lighting industry. Only by having standardized things can we grow and grow so that we can survive for a long time. Through the years of precipitation, the industry especially in the light of this module, has already reached a consensus, many well-known brands are tend to standardization, the future of the industry of small and medium enterprises will gradually standardized, the only standard to gain popularity.
At the same time, Song Dong told reporters: "I personally think that the longest period of three years.". All products will become standardized, LED lighting from 2005 to now, after almost 10 years of time, which precipitated a lot of technology, we believe that in 2017, all products LED lighting in the industry must be standardized."
