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. Solar street lights in the use and maintenance of batteries batteries for solar PV is closely related to the discharge capacity of the discharge current and the ambient temperature, the discharge current to increase or decrease the temperature of Pingxiang solar lights, low battery usage, reducing capacity accordingly. As the ambient temperature increases, the battery capacity is increasing, and vice versa reduced; battery life is also reduced, and vice versa increases. When the ambient temperature is below 25oC, battery float life of 6-8 years; ambient temperature is 30oC, battery float life of 4-5 years; ambient temperature is 30oC, battery float life of 2-3 years; ambient temperature 50oC, the battery float life of 1.5 years.

Solar street lights are low voltage or high-pressure die first, at the same power output of solar street lights, high-voltage LED drive current is much lower than the required low-voltage LED. Such as high pressure with Epistar blue 1WLED example, its forward voltage drop of up to 50V, but also that it can only 20mA drive current 1W output power, while the average forward voltage drop of 3V 1WLED, need 350mA drive current to 1W output power, so the same power output high voltage LED power dissipation during operation is much lower than a good quality low voltage LED solar street light, which means that the heat aluminum housing costs can be greatly reduced. Second, high voltage LED can significantly reduce the loss of AC-DC conversion efficiency. To 10W output power, for example, if the forward voltage drop of 1W high-voltage LED, the output of 50V and can take two 4 string configurations 4 series LED forward voltage drop of 200V, that is to say just from the city 220V AC power (AC) 20V use bridge rectifier and drop it. But if we use the forward voltage drop of 1W LED 3V low pressure, even 10 strung together, but also the forward voltage drop 30V, that is to say the buck from 220VAC mains need to 30VDC. We know that the lower the input and output pressure, AC to DC conversion efficiency is higher, such as the use of high-pressure visible LED, transformer efficiency can be greatly improved, thereby significantly reducing the loss of AC-DC power conversion, which a reduction in heat consumption can be further reduced cooling housing costs.
