Abstract

Recently, progress has been made in the development of projectors used for large screen displays. Projection systems employing Metal Halide lamps as a light source, demonstrate unique and desirable features such as longer life and high luminous efficiency. These features are especially important for data projectors. Compared to conventional lamps, Metal Halide lamps have shorter arc lengths and higher color-rendering characteristics, resulting in overall superior performance. For the Hamamatsu 575 W Metal Halide lamp, we have modified the electrodes and chemical composition of the Metal Halide, as well as the glass envelope, all of which result in improved performance. We have extended the average life to 3000 hours or longer, for a compact, single-bulb, projection-type, 575 W lamp.
