Select the solar lampposts material when we must choose the technical material, such poles have a certain quality assurance. 2. In the time of purchase be sure to look factory, is not a professional manufacturers, manufacturers look at the qualifications and the registered capital, as well as the manufacturer's service to see how, so as to ensure the safety of lampposts. Solar street light pole installation manual 1. Installation time, we must firmly and do not appear loosening. 2. Be sure to choose a suitable location and below the poles must be good protection, both to avoid the poles to bring some personal danger, but also to avoid other people to steal. If the solar street light pole fails during use, be sure to get in touch with the relevant departments, timely maintenance. Nanchang Ou Optoelectronics Technology Co., Ltd.

Solar street lights are low-pressure or high-pressure die first, at the same output power, high-voltage LED drive current is much lower than the required low-voltage LED. As with Epistar high pressure blue 1WLED for example, the forward voltage drop of up to 50V, but also that it is only 20mA drive current can be 1W output power, while the average forward voltage drop of 3V 1WLED, Pingxiang solar lights, 350mA drive current required to 1W output power, so the same power output high voltage LED power dissipation during operation is much lower than the low-voltage LED, which means cooling aluminum housing costs can be greatly reduced. Second, the high pressure can significantly reduce LED AC-DC conversion efficiency losses. To 10W output power, for example, Nanchang solar lights, if the forward voltage drop of 1W high voltage LED, the output of 50V can take 2 and 4 string configurations, four series LED forward voltage drop of 200V, ie Simply use the bridge rectifier from mains 220V AC (AC) and 20V drop it. But if we adopt a forward voltage drop of 1W Low Voltage LED 3V, even strung together 10 forward voltage drop, but also 30V, solar street light processing, that require the buck from 220VAC mains to 30VDC. We know that the lower the input and output differentials, AC to DC conversion efficiency is higher, such as high-pressure visible LED, transformer efficiency can be greatly improved, thereby significantly reducing the power loss AC-DC conversion, which a reduction of heat consumption can be further reduced cooling housing costs.
