AIRCRAFT OBSTRUCTION LIGHT

摘要

PROBLEM TO BE SOLVED: To provide an aircraft obstruction light that has blinking performance capable of satisfying standards as various obstruction lights and especially middle and high intensity obstruction lights, and can light reflection type light emitting diodes sequentially or alternately, can reduce power consumption and is small via an improvement in a blinking method of a light emission part. SOLUTION: The obstruction light comprises: the light emission part comprising the reflection type light emitting diodes having a concave reflecting surface opposed to a light emitting surface of a light emitting device to reflect light emitted by the light emitting device and a radiating surface for radiating out the reflected light substantially parallel, a support disposed in a substantially cylindrical lighting fixture body, and many light emitting diode arrays mounted along the overall circumference of the support; and a power source part disposed in the lighting fixture body. The power source part comprises a light emission control circuit for lighting a plurality of lighting blocks independent in circuitry sequentially in order of circular array, so that the radiated light from the light emission part provides sequential lighting.
