The scope of the spot check included LED street lights and LED street light source controller products produced by 35 companies in 7 cities including Dongguan, Foshan, Guangzhou, Shenzhen, Zhongshan, Zhuhai and Jiangmen.
Among them, Guoxing Optoelectronics and Zhaoxin Lighting Co., Ltd. have failed the product. The product specifications of Guoxing Optoelectronics are NS-LD-N98 (A-NPE) and NS-LD-N154 (A-NPE) respectively; and the unqualified product specifications of Zhaoxin are RFLEDL220/105-WW and RFLEDL220/210- WW.
National Star products are mainly surge (impact) immunity test and radiation disturbance have not passed, and Zhaoxin products are classified as unqualified due to radiation disturbance and power terminal disturbance voltage link failure.
It is understood that the unsatisfactory immunity of the surge (shock) will result in poor lightning protection performance of the LED street light, and the normal operation of the equipment cannot be well protected during thunderstorms. The unsatisfactory radiated electromagnetic disturbance will cause the radio function or effect of the car radio equipment to be affected when the road vehicle is passing through the road section under the street light.
What is Flexible PCB?
Flexible PCB`s are now being used in place of traditional FR4 in a large number of different applications,Benefits include solving interconnecting problems, reduction of weight, reduction of space and reduced assembly costs. Flexible applications can be dynamic flexing (designed for flexing or stress over a period of time at elevated temperatures) or flex & stay applications (designed for flexing once and being secured into place).
Quickly Turn flexible Service.
Not only do we offer flexible PCBs for fast production, we can also provide Flex PCB prototypes to see your custom designs before a big shipment is created. Royal Circuits flex and rigid-flex capabilities are designed to meet a variety of circuit board needs from single or double-sided circuitry to multilayer technology. We also offer different material substrates and adhesives, as well as surface finishes and treatments. Stiffeners can also be added for reinforcement.
Full Product Lines of Flexible Circuits
Our product lines includes single sided flex circuits, dual access flexible PCB , double sided flexible circuit, multi-layer Flex circuits and rigid-flex circuits. We work shoulder by shoulder with our customers to achieve the quality, delivery, and cost objectives for their projects of Flex PCB ( FPCB). We are a flexible printed circuit source that can accommodate your customized program initiatives such as ship to stock.
