After the street light switch test 9000 times, it must still work normally. The average time of failure of the power supply is no less than 25,000 hours. Yesterday afternoon, the reporter learned from the standard conference held by the Shenzhen LED Industry Standards Alliance that it lasted nearly one year. The "General Technical Requirements for LED Street Light Drivers" and the "Interchange of General Interfaces and Key Components for LED Street Lamps", which were jointly developed by Shenzhen Sunda Industrial Co., Ltd. and Shenzhen Bangbeier Electronics Co., Ltd., were officially released. In addition to the technical specifications and energy efficiency requirements for LED road lighting products released in February last year, the Shenzhen LED street lamp production and evaluation standard system was finally established.
In recent years, enterprises have been rushing to the LED street lamp market. Despite the rapid development, there are still no relevant technical standards. The product specifications produced by the company are different, resulting in uneven technical indicators of the whole industry. As Li Jian, general manager of Shenzhen Bangbeier Electronics Co., Ltd. said, enterprises have encountered difficulties in the marketing of LED street lamps: each enterprise produces products according to its own standards, and the enterprise standards are different. The products cannot be compatible and mutually compatible. It is inevitable to formulate technical standards related to LED street lights as soon as possible.
At the same time, in order to promote the development of LED industry in our city, implement the national requirements for the development of semiconductor lighting energy-saving industry, and promote the implementation of the “Ten Cities and Ten Thousand†semiconductor lighting pilot demonstration project in our city. In the past two years, the Shenzhen Municipal Government has successively issued a series of Encourage policies and promote the development of LED lighting products to standardization and modularization from the perspective of saving resources and reducing the cost of use.
It is understood that the "General Technical Requirements for LED Street Light Drivers" has detailed and strict regulations on the performance and technical specifications of LED street light drive power, including power specifications, naming methods, appearance, structure, performance and so on. According to the standard, the customer list can determine whether it meets the requirements from the product naming. For performance requirements, the average time between failures of Class 1 products should be no less than 50,000 hours, and Class 2 products should be no less than 25,000 hours. This means that products with an MTBF of less than 25,000 hours do not meet the requirements of this standard.
At the same time, with the cycle of 30 seconds for the power on and off, the power supply should be able to work within the nominal working range after 9000 consecutive tests under no-load and full load conditions; the operating temperature range of the power supply must be at least 10 degrees to zero. It lasts for 16 hours at the upper limit of 50 degrees and still works normally. In addition, the surface of the power supply should not have obvious scratches, deformations, spikes, dents, cracks, the surface coating should be uniform in thickness, the coating film should be smooth, the welding parts should be flat and firm, and the metal parts should not be rusted or otherwise mechanically damaged. The standard also supplemented the existing LED power supply standards, improved some technical indicators, and further standardized the LED street light driving power supply market.
On the other hand, the standard for the interchange of LED street lamps and key components, which was developed by Shenzhen Bangbeier Electronics Co., Ltd., is to unify the interface interchange of important components of LED street lamps in our city. This standard provides a certain reference and guidance for the healthy and orderly development of the LED street lamp industry in Shenzhen and even in China. It is conducive to the integration of advantageous resources by LED street lamp manufacturers and supporting equipment manufacturers in our city, formulating overall development plans, and promoting mutual cooperation and common cooperation among enterprises. development of.
"Standards have never been the best. They can only be compromised and relatively accepted by all parties under certain conditions." Lin Wei, vice president of Shenzhen Sunda Industrial Co., Ltd., said that enterprises have mastered the standards and mastered the market discourse. right. The existence of standards, first of all, must eliminate enterprises that are not up to the basic requirements, and build a new core competitiveness among enterprises that meet the standards. Sun Xueming, secretary-general of the Shenzhen LED Industry Standards Alliance, appealed that the new industry should introduce new standards as soon as possible, occupy the industry standard high ground, and firmly grasp the market leading power.
