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. What is a solar power system, solar street lighting street lighting system in general small-scale photovoltaic power generation system, the World Bank standards is small PV system controller from the power flow is less than 1% of the rated current, so choose low-power devices and circuit design is very important a. Solar street light is a voltage comparator is an integrated operational amplifier control circuit, the circuit is composed of hardware control system is simple, reliable, easy maintenance, low cost, low power dissipation, is a good match circuit. The key characteristic of this circuit is based on the charge and discharge of the bad design better battery voltage, while the device is reliable choice of solar light which is good, and light-emitting diodes indicating the status of the charging and discharging circuit, a controller circuit having become practical function, to prevent battery discharge, overcharge function. Direct coupling system charging and discharging control circuit, according to the matching of characteristics of the battery LED, can achieve the adaptive power, solar radiation is insufficient solar light month volts, because the battery voltage of the battery state of charge is low, low emissions, the load current small, small power solar lights high pole, the system can work longer.

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, working 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, 24000h, and through the fog because of its better, more suitable for road lighting. (4) low-pressure sodium lamp as the light source, the light 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 solar lights, its life can reach 40000h, no flicker, color better. Jiangxi price of solar lights, Ou 10 meters of solar street lights, solar lights provided by the Nanchang, Xinyu Ou Optoelectronics Technology Co., Ltd .. Nanchang Ou Optoelectronics Technology Co.
