である。 A current limiting element 15 such as a resistor is connected between the generator 5 and the secondary battery 10, and a current limiting element 15 such as a resistor is connected between the headlamp 2 and the secondary battery 10. Rectifying element 16 with forward polarity
are connected. That is, this rectifying element 16 prevents charging of the secondary battery 10 from the generator 5.

手段T2がOFFして前照灯２は消灯している。 To explain the operation of such a configuration, first, when driving in a relatively bright place such as a commercial district during the day or at night, and when driving the generator 5, the output of the generator 5 is controlled by the current limiting element 15. The fifth transistor T5 is turned ON via the third transistor T5 .
The transistor T3 is turned on, and the output of the illuminance detection means 8 turns on the sixth transistor T6 , turns on the fourth transistor T4 , turns off the switch means T2, and turns off the headlight 2. ing.

担が少なくなる。 At this time, the secondary battery 10 is charged by the generator, but because it is via the current limiting element 15, the amount of charge is very small and there is no possibility of overcharging. There will be less strain on your foot when stepping on it.

り、その結果前照灯２が点灯する。 When driving in a dark place at night, there is no output from the illuminance detection means 8, so the sixth transistor T6 and the fourth transistor T4 are turned off, and therefore the fifth transistor T5 and the third transistor T 3 , the switch means T2 is turned on, and as a result, the headlight 2 is turned on.

を回転さす力が少なくてすむ。 At this time, when the power generated by the generator 5 is weak, the lamp is turned on by power supplied from the secondary battery 10 via the rectifying element 16, and thereafter the lamp is turned on by the generator 5. Then, the amount of charge of the secondary battery 10 decreases and the generator 5 attempts to receive power supply, but this is also blocked by the rectifying element 16 and the current limiting element 1
Since the secondary battery 10 is charged via the battery 5, it is difficult to charge the secondary battery 10, and therefore, there is no need to generate electricity for charging the secondary battery 10, and the force required to rotate the pedal of the bicycle can be reduced accordingly.
