Abstract
The water- and air-cooled reflection mirror of this invention, which can be applied to light projector, sterilizing lamp and development device, cools with water and air the reflection mirror that is heated by intense heat of the light source. The water flowing into the water passages formed in the reflection, mirror base body cools the base body to cool the air present in the opening in the base body, thereby preventing overheating of the reflection mirror by the circulating water and cooling air.
