There are light-emitting devices for bicycles / motorcycles that form electric circuits for batteries and light bulbs and light the light bulbs. Japanese Utility Model Laid-Open Publication No. Hei 3-17943 discloses a switch which is provided with a reflector and a luminous body in a housing attached to a spoke of a wheel, and which is turned on / off by centrifugal force generated by rotation of the wheel, and a photoelectric sensor which detects light and darkness. A bicycle safety light has been proposed in which an electric circuit is configured by cells and a battery power is supplied to the illuminant to emit light.

[0003]

Since the former light emitting device uses a light bulb, it consumes a large amount of power, is small in size,
Moreover, it is not suitable for a spoke reflector which is used for a long time without maintenance. In addition, the latter safety light uses centrifugal force as a means for detecting rotation,
There is a problem in the detection of low-speed rotation, and there is a problem in durability because its structure is complicated. The arrangement of the illuminants is only one example, and is always lit. Therefore, the illuminants are rarely changed and lack the alertness of traffic safety.

The present invention eliminates the need for long-term battery replacement due to the reduction in power consumption of the conventional luminous body, is easily and robustly mounted on the spoke, and always flashes and faces the luminous body during night driving. The aim was to dramatically increase the visibility of other transportation systems and to improve the traffic safety of cyclists.
