LAMP AND LIGHTING EQUIPMENT
First Claim
1. A lamp, comprising:
- a thermal conductive hollow base body having a first end portion and a second end portion, including a concave container portion, an opening portion formed at the first end portion so as to communicate with the container portion and a substrate support portion formed at a peripheral portion of the opening portion;
a substrate formed of one of a thermal conductive metal plate and a thermal conductive insulating plate having a first surface and a second surface opposing to the first surface, and including a semiconductor lighting element mounted on the first surface, a peripheral portion of the second surface of the substrate being fixed to the substrate support portion of the base body so as to cover the opening portion in a thermally conductive state therebetween;
a power supply device accommodated in the container portion of the base body to light on the semiconductor lighting element; and
a base provided at the second end portion side of the base body and electrically connected with the power supply device.

Abstract
In one embodiment, a lamp includes a thermal conductive hollow base body having a concave container portion, an opening portion formed at one end portion so as to communicate with the container portion and a substrate support portion formed at a peripheral portion of the opening portion. A substrate is formed of one of a thermal conductive metal plate and a thermal conductive insulating plate and including a semiconductor lighting element mounted on one surface. A peripheral portion of the other surface of the substrate is fixed to the substrate support portion so as to cover the opening portion in a thermally conductive state therebetween. A power supply device is accommodated in the container portion of the base body to light on the semiconductor lighting element. A base is provided at the other end portion side of the base body and electrically connected with the power supply device.
