    • A light source device for a liquid crystal projector in which it is possible to prevent distinct appearance of a shadow of the conducting wiring of a lamp on a screen, even if an integrator lens is used, is achieved according to the invention by the fact that, in a light source device which has a metal halide lamp with bilateral sealed terminations in which seal areas are joined in one piece to two ends of an arc tube, and a concave reflector, in which one of the seal areas of the lamp is installed and held in a base opening of the concave reflector, and in which the other seal area extends in toward the front opening of the concave reflector, by conducting wiring connected to the outer lead pin which projects from the seal area toward the front opening of the concave reflector being positioned running toward the arc tube in a manner resting directly on this seal area, and then being drawn out in the vicinity of the arc tube with to behind the concave reflector.
    • 即使使用积分透镜也可以实现液晶投影仪的光源装置,即使在使用积分透镜的情况下也可以防止在屏幕上的灯的导线的阴影的不同外观, 在具有双边密封端子的金属卤化物灯的光源装置中,其中密封区域一体地连接到电弧管的两端,并且其中安装有灯的一个密封区域的凹面反射器 并且保持在凹面反射器的基部开口中,并且其中另一个密封区域朝向凹面反射器的前部开口延伸,通过连接到从引线销引出的布线,该外部引线销从密封区域向着前述开口突出 凹形反射器以直接搁置在该密封区域上的方式定位成朝着电弧管行进,然后在凹面反射器的后方被引出到电弧管附近。
