PURPOSE:To emit an alarm or signal consisting of differently colored flash light of large power by using a xenon lamp as a light source, and projecting the blinking light therefrom to the outside through one of the color panels differently colored. CONSTITUTION:A case 1 consists of a drum part 2 and lid part 3, wherein the drum part 2 is formed from semi-cylindrically divided drum segments 4, 5 which are joined together. These drum segments 4, 5 are equipped with windows 7, 8 to which differently colored photo-transmissive color panels 9, 10 are fixed. A xenon lamp 11 is installed in the drum part 2 and driven by a driver circuit 12 blinkingly, and the emitted light blinking is reflected by a reflex board 13 and projected to outside the case 1 through the panels 9, 10. Thereby a large power flash light from xenon lamp is colored differently through selection of one of the color panels, and an alarm or signal differently colored can be emitted. |
