PROBLEM TO BE SOLVED: To provide an alarm lamp with diffused light of a simple configuration, emitting light with a peculiar light emission characteristic, having good adaptability to various environments, and raising attention of the viewer. SOLUTION: A rotating light 4 using an electric bulb as a light source 41 and a flash light unit 6 using a discharge tube as light source are installed on a base 1 in appropriate arrangement and covered with a globe 2. A reflection plate 5 is installed between the rotating light 4 and flash light unit 6, and inside the globe 2, an irradiation region by the rotating light 4 and irradiation region by the flash light unit 6 are formed about the reflection plate 5 as boundary. The source lights from optical machine units are cast upon being colored with color applied to the globe 2, and with the spectral distribution characteristic of each light source taken into consideration, red rotating light is emitted from the rotary light 4 while a flash light of yellow or a visible light of shorter wavelength range is emitted from the flash light unit 6. Because the source lights are not cast into the adjacent irradiation region owing to the reflection plate 5, lighting or not can be distinguished clearly. |
