【摘要】 多媒体投影器技术向小型、轻便、高亮度方向快速发展。配套需要的高亮度短弧光源已进入第三代—短弧超高压汞灯 (UHP)时代。该灯近年来由于工艺改进又有较大的进展。发光电弧缩短至 1mm ,寿命可望达到 10 0 0小时以上 ,可组成更紧凑的光学系统 ,为大屏幕液晶背投电视进入市场创造了必备条件。更多还原

【Abstract】 The techniques of multimedia projectors are fast developing to smaller, portable and high bright. The high bright short arc lamps for multimedia projectors have developed into third generation—UHP(Ultra High Pressure Mercury Discharge)lamps. Recently, the UHPs have even more development because of making technology improved. The length of the arc has been decreased to 1mm and the life may be more than 10000 hours. The more compacting optical system can be composed by this system. This system creates the necessary preconditions for Large Screen LCD Rear TV coming into markets.\;更多还原
