Abstract

A light emitting unit of one or more kinds selected from light sources such as, neon lamp, cold cathode fluorescent lamp, electro luminescence (EL), and light emitting diode (LED) accommodated in a protecting enclosure together with a rectifier circuit, is mounted on a rotating body of an automobile such as a wheel or a tire. Power for illumination is supplied from an extra miniature generator installed on the rotating body converting its rotating kinetic energy into electrical energy by means of a specially designed vane, an eccentric swing block, and a bearing disc with associated transmission gear wheel to continuously supply electricity to the light emitting unit. Both sides of the automobile are therefore well illuminated in a dark environment so as to achieve traffic security and contribute to beautiful night scenery.

Claims9

Dependent claims

A light emitting rotating body on an automobile comprising:

a rotating body composed of a wheel, a wheel cap, a hub rotating disc with screw bolts, and a tire inlaid around said wheel;
a generating mechanism including an extra miniature generator mounted on said rotating body, a three dimensional vane for driving said generator rotor, an eccentric swinging block and a bearing disc with associated transmission gear wheel for continuously driving said generator by enhancing rotation of said rotating body so as to generate continuously effective electrical power;
a light emitting unit operatable with AC/DC power supply, accommodated in a protecting enclosure, and connected to an electronic rectifier circuit;
and
a fixing base to be mounted on said rotating body, or to be fixed to the screw unit of air valve seat of said tire;
with this structure, said extra miniature generator is driven by rotation of said rotating body and produces electrical power to supply said light emitting unit.
