In the daytime, soler energy battery GB1 will charge GB2 through VD1. The other circuit will provide D1 and D4 with high level through VD2, and D1's andD4's output terminals will have low level. V1 and V2 are disconnected and VL1-VL4 are not illuminated. At night, VD1 and VD2 are disconnected. GB2 will provide the circuit with working voltage. When the multivibrator begins to work, D3's output terminal will output low frequency oscillator signals which will illuminated VL1-VL4. When the signal has high level, VD3 is connected and D1's andD4's input terminals have high level and their output terminals have low level. V1 and V2 are disconnected. VL1-VL4 are not illuminated. When the signal has low level, VD3 is disconnected. V1 V2 are connected and VL1-VL4 are illuminated.
