On December 24, the General Administration of Quality Supervision, Inspection and Quarantine announced the results of the national supervision and spot check on the quality of 17 types of products in 2011, including the road and street lighting products, Shandong Jinyuan Qinshang Optoelectronics Co., Ltd. (hereinafter referred to as “Jin Yuanqin†"") An LED street light was detected unqualified.
This time, a total of 72 road and street lighting products produced by 72 enterprises in 11 provinces and municipalities including Tianjin, Liaoning, Shanghai, Jiangsu, Zhejiang, Fujian, Jiangxi, Shandong, Henan, Guangdong and Chongqing were sampled. However, the final monitoring results are not optimistic, the pass rate is only 58.3%, which means that more than 40% of the products do not meet the standards.
The reporter noticed that Jin Yuanqin's unqualified LED street light product model is KS-A182TX. The unqualified items have external wiring cross-sectional area, anti-electric shock protection, dustproof, waterproof and heat resistance.
According to the Qinshang Optoelectronics Prospectus, Jinyuanqin is a holding subsidiary with a registered capital of 50 million yuan.
In fact, the fist product of Qinshang Optoelectronics is the LED street light. As the main drafter, the company participated in the formulation of the first local LED street light standard in China--"Guangdong Province LED Street Light Local Standard". In addition, Qinshang Optoelectronics is also a member of the Working Group of Semiconductor Lighting Technology Standards of the Ministry of Industry and Information Technology. It has participated in the drafting of industry standards such as "Performance Requirements for LED Lighting for Road Lighting" and "LED Lamps for Decorative Lighting".
In September this year, the company completed the deep high-speed LED lighting street light and tunnel light project, which is the first highway project in China to apply LED street lights on a large scale. According to the company's prospectus, in the first six months of this year, the outdoor lighting business, which is dominated by LED street lights, accounted for 53.98% of the company's total revenue.
The diligent LED street lights were unqualified, adding to the concerns of the outside world about the quality of the company's products. However, the company's secretary-general Weili said in an interview with the "Daily Economic News" reporter that the batch of products that were sampled before the production was produced before 2010, and the total number of products was only 8 ç›. This batch of products was placed in the warehouse at the time, only for display, not for supply.
“The products displayed for the convenience of disassembly, to the customer, some interfaces (the standard) is not a standard that can be used directly outdoors.†Wei Li stressed that after the adjustment, the products of Qinshang Optoelectronics are in accordance with national standards. Production is qualified.

SBD is an abbreviation for Schottky Barrier Diode (abbreviated as SBD). SBD is not fabricated by the principle of forming a PN junction by contacting a P-type semiconductor with an N-type semiconductor, but by a metal-semiconductor junction principle formed by metal-to-semiconductor contact. Therefore, SBD is also called a metal-semiconductor (contact) diode or a surface barrier diode, which is a hot carrier diode.
