Optoelectronics Technology Co., Ltd. Nanchang Ou main products are: solar lights, solar garden lights, solar lawn lights, solar wind hybrid street light series; a variety of LED light sources, solar PV modules, batteries, controller; various lampposts, patio poles, waterproof box and supporting the use of flip-flops, light control when the control switch and other electrical products. Solar lighting products are green, safe, energy-saving features. Recognition of quality LED power a bad skill, PFC (power factor) level but not necessarily high PFC is good, even smaller overall ramp, ripple, low interference (because some manufacturers do very deliberately PFC high but ignored this part of the electromagnetic compatibility). Second, the conversion efficiency of the conversion efficiency of the height, size and stability of the cost of solar street lights, an analogy deviation values: AC170-250V The operating voltage range of 4 m solar street price, I can try to debug from 170V-250V, from low to high changing the voltage, you can see the fluctuations "conversion efficiency, PFC" whether big on the power meter to prove its stability. Third, look at the power of the temperature is high. The power supply itself higher the temperature, the greater the damage to the components. Fourth, the cyclical aging test continuous power with light aging, uninterruptible power supply can also be detected in about one month beads decay heat lamp and lamp housing is good. Fifth, the boot is instantly detect the lamp beads inrush current. Six constant current stability testing. Optoelectronics Technology Co., Ltd.

Solar lighting products are green, safe, energy-saving features. Solar street light construction principles: 1, concentrated in the focus, Bao period, in terms of manpower, material and equipment to the construction with full guarantee, the professional management of high-quality solar street lights should help to guide the construction of the project team to organize the construction work , improve coordination in all aspects. 2, according to hand over the order to organize the phased construction; comprehensive arrangements for solar lights, in the shortest possible time, to achieve the intended purpose. 3, the organization with the construction, interspersed operations; 4, the implementation of advanced construction methods and construction equipment, improve the level of mechanization 4 m solar street price, Chang Dong solar lights, solar street light wind Ou Ou by Optoelectronic Technology Co., Ltd. Nanchang. Nanchang Ou Optoelectronics Technology Co., Ltd. (www.okled.cn) strong, credible, in Nanchang, Jiangxi solar and renewable energy industry has accumulated a large number of loyal customers. The company better work attitude and constantly improving innovative ideas will lead Europe to photoelectric and you hand into the brilliant, for a better future!
