<p><P>PROBLEM TO BE SOLVED: To provide a bicycle headlight capable of being put on with small power generation and high efficiency. <P>SOLUTION: The bicycle headlight is formed with a light emitting diode 1 having less power consumption. A magnet 4 is placed on a wheel for a power generating coil 3 to generate power during the travel of a bicycle and the generated power is stored in a secondary battery 2. A brightness and darkness sensor 5 senses the brightness of day and the darkness of night and charged in the daytime during the travel of the bicycle. In the nighttime during travel, the light of the light emitting diode 1 is controlled by a computer or a controller 6. <P>COPYRIGHT: (C)2004,JPO</p> |
