Lighting device having a through-hole and a groove portion formed in the thermally conductive main body
First Claim
1. 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;
whereina 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.

Abstract
A lighting device and a lighting fixture of the embodiment of the present invention comprises a thermally conductive main body having a substrate support portion in one end portion, and having a through-hole and a groove portion formed in the substrate support portion, the through-hole penetrating from the one end portion to the other end portion of the main body, the groove portion extending continuously from the through-hole, a substrate mounted with a semiconductor light-emitting device, and disposed on the substrate support portion, an electrical connector 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 connected to the power supply device and to the electrical connector while being inserted through the through-hole and the groove portion, and a base member provided in the other end portion of the main body and connected to the power supply device. Therefore, a lighting device and a lighting fixture of this embodiment of the present invention reduced in size, is configured to be suitable for mass production and is capable of producing a certain luminous flux.
