Claims

[Claims for Utility Model Registration] 1. Two power sources, a generator and a battery, attached to the body of a bicycle, at least one lamp, and the battery as a power source for the lamp when the speed of the bicycle is less than a predetermined value. and a selection switch that selects a generator as a power source for a lamp when the value exceeds a predetermined value. 2. The bicycle lighting device according to claim 1, further comprising a manual switch for forcibly selecting the generator as a power source for the lamp. 3. The bicycle lighting device according to claim 1, further comprising a light switch that forcibly selects the generator as a power source for the lamp when the surrounding brightness is above a predetermined value. 4. Claim 1, wherein a portion of the bicycle lighting device other than the generator is configured to be detachable from the bicycle body.
The bicycle lighting device according to any one of 3 to 3. 5. At least one of the lamps and a portion other than the generator are configured to be removable from the bicycle body, and the lamp remaining on the bicycle body after removal is powered by the generator, and the removed lamp is powered by the generator. The bicycle lighting device according to any one of claims 1 to 3, which can be lit independently using a battery as a power source. 6. The bicycle lighting device according to claim 1, wherein the selection switch is constituted by a relay that selects a power source based on a rectified value of the generated voltage of the generator corresponding to the speed of the bicycle.
