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 Solar street light poles, waterproof box and supporting the use of triggers, control switches and other electrical products light control. Solar lighting products are green, safe, energy-saving features. LED series and parallel with PFC power factor electronic components within the rated voltage range operating current smaller heat the bottom longer life, life will be shorter and vice versa. AC power LED lights bead weight is very sensitive to exchange higher light weight comfort worse. Generally use an electrolytic capacitor to maintain the voltage, the output voltage of the AC minimize weight, the bottom end of the electrolytic capacitor voltage capacity can not be too small, the capacity and output current ratio of 1 UF <1.5 MA otherwise LED will flicker. Non-isolated inputs and isolated high voltage capacitors choose the same type, the output capacitor selection 1 UF <6 MA. Dimming LED power at the output of electrolytic capacitors to meet 1U F <0.5 MA. 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. Comparison of different types of source selection and solar lights (1) tricolor energy-saving lamp as the light source, the light efficacy reaches 60Im / w, and light color, low cost, service life can reach 000h, a wide range of applications. (2) Led as the light source, the light efficacy reaches 60-80Im / w, life can come to 30000h photovoltaic solar street sales, work at low pressure, no UV IR radiation, power adjustable. (3) high-pressure sodium lamp as the light source, the light efficacy reaches 100-120Im / w solar street quote form, 24000h, and through the fog because of its better, more suitable for road lighting. (4) low-pressure sodium lamp as the light source of solar street light installation contract, its luminous efficacy reaches 150Im / w or more, life can reach 28000h, although through the fog is better, but noticeable chromatic aberration. (5) lamp as a light source, the light efficacy reaches 50-70Im / w, its life can reach 40000h, no flicker, color better. 120w solar lights, solar street lighting standards Ou, Jiangxi Nanchang solar street lights provided by the EU can Optoelectronics Technology Co., Ltd .. Nanchang Ou Optoelectronics Technology Co. (www.okled.cn) Jiangxi Nanchang, solar and renewable energy leader, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs. In Europe may photoelectric leadership with the staff warmly welcome all inquiries negotiations to create Europe can photoelectric a better future.
