Description

The present invention relates to an LED illuminator for rotating lanterns in which an LED illuminator incorporated in the rotating lantern is rotated.

Conventionally, a rotating lantern that uses an incandescent bulb instead of a candle is commercially available. In such a rotating lantern, the heat of the incandescent light bulb rises, and the rotation of the light is produced by rotating the aluminum body by turning the aluminum blade provided on the upper part of the fire bag part (cylindrical body). .
In recent years, LEDs (light emitting diodes) have been used as light sources for lighting devices. Since these LEDs have a longer life and less heat generation than incandescent bulbs, a plurality (two or more) of these LEDs can be used side by side.
Then, as in JP 2012-94264 A (see Patent Document 1) and JP 2012-226934 A (see Patent Document 2), there is a rotating lantern that incorporates an LED illuminator instead of a candle or an incandescent bulb. Has been proposed.
