Shenzhen introduced LED street lighting standard

The street light switch must be able to work normally after 9000 tests. The average time for failure of the power supply should not be less than 25,000 hours.... Yesterday afternoon, the reporter learned from the standard conference hosted by Shenzhen LED Industry Standard Alliance that it lasted for nearly 1 year. Shenzhen Sunda Industrial Co., Ltd. and Shenzhen Bangbel Electronics Co., Ltd. jointly formulated the "General Technical Requirements for LED Street Lamp Driver Power Supply" and the "General Requirements for LED Street Lamps and Key Components Exchanged" standard. In addition to the LED road lighting product specifications and energy efficiency requirements announced in February last year, Shenzhen LED street lamp production and evaluation standard system was finally announced.

In recent years, companies have taken the lead in the LED street lighting market. Despite the rapid development, there are still no relevant technical standards. The product specifications produced by the companies vary, resulting in uneven product technical indicators across the industry. As Li Jian, general manager of Shenzhen Bangbel Electronics Co., Ltd. put it, enterprises have encountered difficulties in the promotion of LED street lamps: Each company produces its own products according to its own standards. The company's standards are different, and products are incompatible and mutually exclusive. Change, as soon as possible to develop relevant technical standards for LED street lamps has become inevitable.

At the same time, in order to promote the development of the city's LED industry, the implementation of the national semiconductor lighting energy-saving industry development requirements, to promote the "Ten Thousands of Miles" semiconductor lighting pilot demonstration project in the smooth implementation of the city, since 2009, the Shenzhen Municipal Government has successively issued a series of Encourage policies, and at the same time promote the development of LED lighting products to standardization and modularization from the perspective of saving resources and lowering the cost of use.

It is understood that "General technical requirements for LED street lamp driving power supply" has formulated detailed and strict regulations on the performance and technical specifications of LED street lamp driving power, including power specifications, naming methods, appearance, structure, performance, and so on. According to this standard, customers can determine whether they meet the requirements by naming products. In terms of performance requirements, the average time between failures of Class 1 products should not be less than 50,000 hours, and Class 2 products should not be less than 25,000 hours. This means that products with an average time between failures of less than 25,000 hours are no longer in compliance with this standard.

At the same time, with a 30-second cycle, the power supply shall be able to operate within the nominal operating range after 9,000 tests under no-load and full-load conditions; the operating temperature range of the power supply shall also be from minus 10 degrees to zero. In the limit test state of 50 degrees for 16 hours, it can still work normally. In addition, the power supply surface should not have obvious scratches, deformation, spikes, dents, cracks, the surface coating should be uniform thickness, smooth coating, the welding site should be flat and solid, metal parts should not have rust and other mechanical damage. The standard also supplements the existing LED power supply standards, improves some technical indicators, and further standardizes the LED street lamp driver power supply market.

On the other hand, the "LED Street Lamp Universal Interface and Key Components Interchange" standard led by Shenzhen Bombbell Electronics Co., Ltd. is to unify the interchangeability of key components of LED street lamps in our city. This standard provides certain reference and guidance for the healthy and orderly development of LED street lamps industry in Shenzhen and even in China. It is beneficial to LED street lamp manufacturers and supporting equipment manufacturers in our city to integrate superior resources, formulate overall development plans, and promote mutual cooperation between companies. development of.

"The standard has never been the best. It can only be the result of compromise and relative acceptance of the parties under certain conditions." Lin Wei, vice president of Shenzhen Sunda Industrial Co., Ltd. said that if the company has mastered the standards, it will also grasp the market discourse. right. The existence of standards requires that we first eliminate companies that cannot meet basic requirements, and build new core competencies among companies that meet the standards. Sun Xueming, secretary-general of Shenzhen LED Industry Standards Union, called for this. The new industry should introduce new standards as soon as possible, occupy the industry standard high ground, and firmly grasp the market dominance.
