    • To aim to provide a simple high-pressure discharge lamp apparatus. The lamp apparatus suppresses local temperature increase in an arc tube during lighting, and uniforms temperature in the arc tube. A lamp is built into a reflector so as to form a lamp unit such that a central axis of the lamp coincides with an optical axis of the reflector. A pair of rotating bodies with a fixed interval therebetween each has a circular outer circumferential surface, and the optical axis of the reflector coincides with a central axis of the circumferential surface of the rotating bodies. A pair of electrodes is electrically connected to the circumferential surface of each rotating body, and the rotating bodies are placed on two rotating rollers arranged in parallel. A drive motor drives the lamp unit in a fixed direction on the rotating rollers. Feeding members feed the rotating bodies with power.
    • 旨在提供一种简单的高压放电灯装置。 灯装置抑制点灯期间电弧管的局部温度升高,并且使电弧管中的温度均匀化。 将灯构建在反射器中,以形成灯单元,使得灯的中心轴与反射器的光轴重合。 一对具有固定间隔的旋转体具有圆形的外周面,反射体的光轴与旋转体的周面的中心轴重合。 一对电极与每个旋转体的周面电连接,并且旋转体被放置在平行布置的两个旋转辊上。 驱动电机在旋转辊上沿固定方向驱动灯单元。 进给构件用动力给旋转体供给。
