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.

Provided is a bulb-type lamp including a lightweight housing with great handleability. An LED light bulb comprises: an LED module on which LEDs are mounted; a cylindrically-shaped case having openings at both ends, which are first and second ends; a mount member on a front surface of which the LED module is mounted, the mount member closing a corresponding one of the openings of the case by being in contact with an inner circumferential surface of the first end of the case; a base member attached to the second end of the case; and a lighting circuit that is disposed inside the case. A wall thickness of the case is in a range of 200 &#x3bc;m to 500 &#x3bc;m inclusive, and the wall thickness of at least one portion of the case decreases from the first end toward the second end of the case.

Bulb-type lamp and lighting device

One end of a cylindrical mountis attached to an end of a cylindrical basethat is to be inserted into a socket of a lighting fixture. The end of the mountis rotatable around a central axis of a base. A supportis attached to other end of the mountso as to rotate integrally with the mount. An LED modulethat includes a plurality of LED chips is attached to the support. An end face, on which the LED moduleis attached, is provided on the support. The end faceis formed so that the direction of light emitted by the LED chips provided on the LED moduleis inclined at a predetermined angle with respect to the axial direction of the base
