Abstract
Generally the high-pressure mercury lamp has used as a light source for projectors. The comparatively large-size and low luminosity light source is sealing by the reflector and the front glass, for example, the light source for projection TV. However, the light source for front projectors which required small-size and high luminosity is not sealed unexceptional. When a luminescence pipe explodes, it is difficult for the non-sealed light source to prevent scattering of mercury and shattered glass completely. We study about small, sealing, and high-luminosity light source for projectors.
About 130W of inputs is a limit for sealed light source of the projectors because of the problem of luminescence pipe cooling. However, we found out the possibility of a high luminosity, small-size, and sealing light source by the development of a four-layer structure reflector.
