<P>PROBLEM TO BE SOLVED: To obtain a warning light low in power consumption, long in service life and not dazzling even at a short distance. <P>SOLUTION: The warning light includes a plurality of light emitting elements 1 arranged so that the light emitting direction may be radial with a main axis as a center, a reflector 4 reflecting virtual images of the plurality of light emitting elements 1 and a control circuit controlling on/off-operations of the plurality of light emitting elements so that light radiated from the virtual images of the plurality of light emitting elements on the reflector 4 and light radiated from real images of the plurality of light emitting elements are rotated and moved in the main axis direction in parallel. Thus, the light from the light emitting elements can be effectively utilized without a mechanical rotating mechanism. <P>COPYRIGHT: (C)2010,JPO&INPIT |
