PURPOSE:To improve the cooling effect of a light source device, in which metal- vapor discharge lamps are incorporated. CONSTITUTION:In a variable color light source device, a cooling fun 2 is provided in the ceiling surface of a box-type case 1, of which front surface is opened, and a diffusion plate 3 for cutting the color mixture and the ultra violet rays is fitted to the front opening of the box-type case 1, and furthermore, a reflector 4 is provided inside of the box-type case 1, and metal-vapor discharge lamps 5, 6, 7 are arranged inside of a space surrounded by the reflector 4. A passage 12 for the cooling air from the cooling fun 2 is formed between an upper reflector 41 and a lower reflector 42. |
