如图2所示，实施例一的电路包括一个驱动电路，该驱动电路包括一个光控开关、一个发光强弱控制开关和一个DC/AC变换驱动电路，光控开关保证白天蓄电池储存电能无需消耗，晚上自动控制发光，而发光强弱控制开关能使用户手动选择控制不同条件及环境要求下光源的发光强弱，该驱动电路的电源输入端与蓄电池E的正极之间连接有一电源开关K1，该驱动电路中DC/AC变换驱动电路的输出端接冷阴极荧光管CCFL，驱动冷阴极荧光管CCFL发光；太阳能电池U的正极经过整流二极管D后与蓄电池E的正极相接，太阳能电池U的负极与蓄电池E的负极相接。
如图2所示，所述光控开关包括光敏电阻RP、三极管Q3、三极管Q4、电阻R3、电阻R4，电源开关K1的一端与蓄电池E的正极相接，另一端同时与电阻R3、三极管Q3的发射极相接，电阻R3的另一端同时接光敏电阻RP和三极管Q4的基极，光敏电阻RP的另一端与三极管Q4的发射极接地，三极管Q3的基极经电阻R4后接三极管Q4的集电极，三极管Q3的集电极接发光强弱控制开关的开关接点A；所述发光强弱控制开关包括开关接点A、B、C、D，及三极管Q5、偏压电阻R5、偏压电阻R6、滤波电容C1，开关接点A、B、C、D与电源开关组成一个复合波段开关，开关接点A与三极管Q3的集电极相接，开关接点B与三极管Q5的发射极相接，三极管Q5的集电极与开关接点C相接，三极管Q5的基极与偏压电阻R5串联后接地，偏压电阻R6接在三极管的基极与开关接点C之间，开关接点D接DC/AC变换驱动电路的输入端，滤波电容C1的正、负极分别接开关接点和地；所述DC/AC变换驱动电路包括储能电感L1、变压器T1、三极管Q1和三极管Q2，电感L1的输入端与发光强弱控制开关中的开关接点D相接，电感L1的另一端与电阻R1串接后接三极管Q1的基极，同时与电阻R2串接后接三极管Q2的基极，三极管Q1的集电极与变压器T1初级绕组的同名端相接，其发射极接地，三极管Q2的发射极接地，其集电极与变压器T1初级绕组的的另一端相接，在三极管Q1的集电极与三极管Q2的集电极之间连接有一电容C2，三极管Q1的基极还与变压器T1的反馈饶组的同名端相接，三极管Q2的基极与变压器T1的反馈饶组的另一端相接，变压器T1的中间抽头接电感L1的输出端，变压器T1的输出端即其次级绕组产生高压，经电容C3后与冷阴极荧光管相接。

白天，太阳能电池U在接收到太阳光后产生电压，直接经二极管D向蓄电池E充电，同时光敏电阻RP接收到阳光后电阻变小，三极管Q4关断，Q3关断，光控开关在白天时自动关闭，DC/AC变换驱动电路不工作，冷阴极荧光管不发光。
晚上，光敏电阻RP在一定光照以后，三极管Q4导通后，三极管Q3导通，光控开关打开，蓄电池E通过电源开关K1对后面电路供电，开关接点A、B、C、D和电源开关K1组成一个复合波段开关，开关接点B、C间是一个限流控制部分，起到光亮度调节，当需强光时人工把开关接点A、D相连；需弱光照时把开关接点A、B相连，同时把开关接点C、D相连。DC/AC变换驱动电路为自激式晶体管逆变电路，其输出端即次级线圈产生高压，向冷阴极荧光管供电，冷阴极荧光管在晚上发光。
上述实施例采用太阳能输出电压直充式，太阳能硅片选用输出电压高于蓄电池电压。本实用新型在太阳能电池U1与蓄电池E1之间还可设一个宽电压DC/DC变换充电电路13，如图3所示。该充电电路从3.5-15V输入电流范围内，经DC/DC脉宽调制变换输出一稳定电压供蓄电池E1充电，采用宽范围电压调制能有效利用白天日照时间，延长光转化效能。
本实用新型中的DC/AC变换驱动电路还可采用输入直流低压经脉宽调制控制电路，推挽逆变输出冷阴极荧光管所需电压，控制冷阴极荧光管在恒流条件下发光。
