Abstract
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.
