があう友。Ninth, a rechargeable generator is used. This conventional rechargeable power generator uses one coil to both light the lamp and charge the lamp. However, lighting the lamp requires a large current, and charging the battery requires a high voltage higher than the battery voltage, so a coil with a thick wire diameter and a large number of turns must be used, resulting in a large A friend who has the problem of becoming

A coil A/3 for low voltage and high current for lighting each 111fi12KF1 lamp and a coil 4 for high voltage and low current for charging are wound. The high voltage coil 4 has a thin wire diameter and a large number of turns. A friction wheel (not shown) that rolls into contact with a tire of a company bicycle is attached to a six-rotor 5 in which a rotor 5 made of a multipolar permanent magnet is arranged inside the magnetic Wa 20.

るように連動するものである。FIG. 3 shows a bicycle lamp lighting circuit using this power generation-6. Both coils A/3 and 4 of power generation-6 are connected to the rechargeable battery 7 via a rectifier 8.9 for preventing backflow from this battery 7, and the rectifier II8 of low voltage coil #3@ and the battery A constant voltage diode 10 for overvoltage prevention is interposed between the voltage regulator 7 and the voltage regulator 7. The pump 11 is connected between the negative electrode of the coil A'3.4 and the battery 7, and the rectifier 8 of the low voltage coil Iv3. A switch 12 is provided to open the lamp 11 and the negative electrode of the coil Iv3.4, and a switch 13 is interposed in the circuit connecting the lamp 11 and the positive electrode of the battery 7. These switches 12 and 13 are interlocked so that opening and closing are reversed.

る。With this configuration, the switch 12 as shown in FIG.
When the switch 13' is closed and the switch 13' [- is opened, when a current is generated in both coils A/3.4 by the rotor 50 revolutions, the lamp 11 is lit by the low voltage coil A/3, and the high voltage The battery 7 is charged by the coil IL/4. Charging current is 0. It is IC charging. At this time, regardless of the amount of afterglow in the battery 7, no current flows through the constant voltage diode lO. This is because the battery voltage is generated at approximately 1.3V. As described above, the batteries 7 are charged to some extent and the voltage of each battery 7 is 1. When the voltage exceeds s v, the constant voltage J4
t-)'10 starts to be energized, and the current in the 111Kt battery 7 flows. Therefore, overcharging is prevented and the battery 7 is protected. In this way, while the generator 6 is generating electricity, it is constantly charged.
また、スイッチ１２を開、スイッチ１３を閉とすれば、
電池７のみでランプ１１が点灯される。Also, if switch 12 is opened and switch 13 is closed,
The lamp 11 is lit using only the battery 7.

のに比べて発電機６を小層化することができる。In this way, the generator 6 can directly light the lamp 11 and charge the battery 7, but the '77 de 11 lighting uses the low voltage coil 3 with a small number of turns, and a wire is used for charging. Since a high-voltage coil A/4 with a small diameter is used, the generator 6 can be made smaller in size compared to a conventional coil with a thick wire diameter and four more turns.

例と同様に小層化を図ることができる。I! Figure 4 shows an example of a pond. That is, the coil J4/3' for low voltage and high current and the coil A/4' for high voltage and low current are each wound in 111 fM2. The pond is similar to the 111 embodiment. Even with this configuration, the load characteristics as shown in FIG. 2 can be obtained, and the layers can be made smaller as in the Igl embodiment.

ある。As described above, since the bicycle generator of the present invention is equipped with a coil for generating low voltage and high current and a coil for generating high voltage and low current, it can be used for both direct lighting and charging of lamps. It has the effect of being able to be used in a smaller size.
