PROBLEM TO BE SOLVED: To provide a pseudo-rotation warning lamp which generates rotating warning light superiority in visibility from a distant place by a structure which requires no rotation drive mechanism.SOLUTION: A globe 3 and a holder 4 are installed on a chassis 2 of a vehicle-mounted warning lamp 1, and a light source unit 5 is installed on the holder 4. The light source unit 5 generates warning light which rotates artificially and radiates in all circumferential region of a vehicle. A plurality of reflecting mirrors 7 and LED light sources 9 are installed on the light source unit 5 and are arranged around a vertical axis, and are fixed at a regular position of a chassis 2 by the holder 4. A light source circuit 11 controls in order the current flowing in each LED light source 9 and rotates artificially warning light from the reflecting mirrors 7. Each reflecting mirror 7 has a reflecting surface which reflects a part of light from the LED light source 9 in the same direction as that of the adjoining reflecting mirrors 7 and emits the warning light downward including a horizontal plane. |
