Abstract

A light emitting apparatus for a bicycle includes a pulse generator (IC, C1, R1, R2) for generating pulses having a predetermined period and a predetermined duty cycle, a light emitter (L) for emitting light when a voltage is applied, and a voltage applying apparatus (10) for applying a voltage to the light emitting apparatus in response to the generated pulses, and the pulse generator generates pulses which allows the light emitted from the light emitter to be visually recognized as light continuously emitted, by a person. Namely, the voltage is applied intermittently to the light emitter, such that the light emission by the light emitter can be visually recognized as light continuously emitted. Therefore, by the light emitting apparatus for the bicycle, brighter light can be emitted and power consumption by the circuit as a whole can be reduced, as compared with the prior art.
