Description

[0001]
[Technical field to which the invention belongs]
The present invention relates to a light-emitting diode blinking spoke reflector for bicycles that can automatically drive a light-emitting diode during night driving, and that can reflect an irradiation light for safe driving.
[0002]
[Prior art]
Many proposals have been made to equip bicycle wheels with light emitters. In Japanese Utility Model Laid-Open No. 49-31386, a fixed contact and a movable contact piece are provided on a casing attached to a spoke of a wheel, and the movable contact piece is brought into contact with or separated from the fixed contact by centrifugal force due to the rotation of the wheel. There is a light emitting device for bicycles and motorcycles that is configured to make an electric circuit of a battery / light bulb when in contact and light the light bulb.
Japanese Utility Model Laid-Open No. 3-17943 discloses a case in which a casing attached to a spoke of a wheel is provided with a reflector and a light emitting body, a switch that is turned on / off by a centrifugal force generated by the rotation of the wheel, and a photoelectric that detects light and dark. Bicycle safety lights have been proposed in which an electric circuit is constituted by cells and battery power is supplied to the luminous body to emit light.
[0003]
[Problems to be solved by the invention]
Since the former light-emitting device uses a light bulb, it consumes a large amount of power, is small, and is not suitable for a spoke reflector that is used maintenance-free for a long time.
The latter safety light has a problem in detecting low-speed rotation because it uses centrifugal force as a means for detecting rotation, and has a problem in durability because its structure is complicated. Moreover, regarding the arrangement of the light emitters, only one embodiment is shown, and since it always lights up, it is poor in change and lacks traffic safety notification.
[0004]
The present invention eliminates the need for long-term battery replacement by reducing the power consumption of such conventional light emitters, and is easily and robustly attached to the spokes. It was made for the purpose of dramatically improving the visibility of the bicycle and improving the traffic safety of bicycle riders.
