A wireless managonent systean for solar street lamp based on nanoLOC AVR nttlule is researched in this paper, the system can real-timely detect the solar street lamp＇s battery voltage, corrent, tonperature, internal resistance, residual capacity and so on. And the collected data is transmitted to computer＇ s management via wireless connnunication to achieve recording, storage, analysis and processing for various parameters.展开更多

Based on the simulation by optical software TracePro,a physical street lamp system including 600 white LEDs was achieved. This system was operated under a constant current of 20 mA for each unit,and the electric power consumption of the whole lamp was only 42 W. Experimental results demonstrated that the total average illuminance reached 8.8 lx and the overall uniformity was 0.370 for a 30-m-long and 10-m-wide test area at a height of 8 m,which is fully acceptable for the current standard for sub-main road.展开更多
