本发明的工作原理是：本发明双电源LED灯供电电路具有三种供电方式，光伏供电、风力供电和市电供电，其中光伏供电和风力供电是基于蓄电池储能技术实现的，并不局限于当时的环境状况，系统设置有电压检测和智能切换开关，从而实现了市电和两种节能供电方式之间的切换，优先选用节能电源，当节能电源的储存电能出现不足时才会切换到市电供电，同时还具有光控和时间控制的功能，能够实现灯具在傍晚时候开启，在凌晨夜深人静时自动关闭的功能，本发明还设计了无线传输模块，能够对电源的状态进行监控，当遇到供电部分出现故障时，可以通过无线传输模块发出远程报警信号，提醒人们检测设备，因此本发明具有功能多样、节能环保和使用方便的优点。报警模块用于实现近距离的报警。其中光伏发电模块的电路如图2所示，太阳能板T完成光电转换并将电能通过止逆二极管D1传输给电路，一部分用于蓄电池E的充电作为备用电源，另一部分用于锂电池的供电，不使用时断开开关S1，能够有效减少电路中的静态功耗，需要使用时闭合开关S1，若不接锂电池A，三极管V1因无基极电压而截止，三极管Q1也截止，无电压输出。此时只有电源指示灯D1发光，能够提醒人们接上负载或者断开开关以防止电能浪费，充电过程：当正确接上锂电池A后，MOS管Q1因电池的余电而轻微导通，其漏极电位下降，Q1迅速导通，输出电压升高；由于C2起正反馈作用，电路状态迅速达到稳态。此时，Q1、V1导通、V2截止，给锂电池A充电，如果充电电流大于限定值，电流取样电阻R6两端电压升高，三极管V2的BE极间电压高于死区电压，单稳触发器状态被触发。V2导通，Q1、V1截止，充电停止；而后单稳触发器自动复位，又进入充电状态，这样周而复始地进行脉动充电。随着充电的进行，锂电池A两端电压缓慢上升，脉宽变窄，充电电流变小，待电池接近充满时，二极管D3导通，V2也导通，Q1、V1截止，关断了充电通电路，结束充电。
