摘　　要：针对LED恒流驱动电源在太阳能路灯中的应用,介绍可调光LED恒流驱动电源的设计方案。研究升压式变换器的工作原理,完成恒流驱动电源元器件参数的计算与选择,搭建整机硬件电路并完成相关数据测量,驱动电源能耗可在0.835 8~11.483 4 W之间连续调节。实验结果表明,设计的太阳能路灯可调光驱动电源设计原理正确,方案可行,而且可调光技术的应用有效地延长了太阳能路灯蓄电池的供电时间,具有一定的实用价值。Aiming at the application of the LED constant current driving power to solar energy street lamps,a design scheme of the dimmable LED constant current driving power is introduced. The working principle of the boost converter is studied. The calculation and selection for component parameters of the constant current driving power supply are completed. The hard ware circuit of the whole machine is built,and the related data measurement is completed. The energy consumption of the driv ing power can be continuously adjusted from 0.835 8 W to 11.483 4 W. The experimental results show that the designed dimma ble driving power supply of the solar energy street lamp has correct design principle and feasible scheme,and the application of the dimmable light technology can effectively prolong the power supply time of the solar energy street lamp battery,w hich has a certain practical value.
