Patent ID: 8760042

Claim:
A lighting device comprising: a thermally conductive main body having a substrate support portion in one end portion, and having a through-hole portion formed in the substrate support portion and a groove portion formed in the substrate support portion, the through-hole portion penetrating from the one end portion to the other end portion of the main body in a first direction, the groove portion extending continuously from the through-hole portion at one end of the groove portion in a second direction substantially perpendicular to the first direction to another end of the groove portion; a substrate mounted with a semiconductor light-emitting device, and disposed on the substrate support portion of the main body; an electrical connector disposed on one end portion of the substrate and connected to the semiconductor light-emitting device; a power supply device housed in the main body and configured to light the semiconductor light-emitting device; a wire having one end connected to the power supply device and the other end connected to the electrical connector while being inserted through the through-hole and the groove portion of the main body; and a base member provided in the other end portion of the main body and connected to the power supply device; wherein a notch-shaped wire insertion portion is formed in a peripheral edge of the substrate; the substrate is disposed on the substrate support portion of the main body in such a manner that the notched-shaped wire insertion portion faces the groove portion and the substrate covers the through-hole and the groove portion except at the other end of the groove portion; and the wire is bent at the other end of the groove portion.
