Headlamp
First Claim
1. A headlamp employing a light-emitting diode, comprising:
- a prescribed casing;
a battery case formed in said casing and accommodating a battery for providing prescribed power to said light-emitting diode;
a substrate portion provided in said casing, spaced apart from said battery case, and mounted with said light-emitting diode and serving as a heat sink;
a partition arranged on a side of said battery case to face said substrate portion, and being spaced from said substrate portion; and
a vent hole formed through said partition for circulation of the air between the space that is provided between said substrate portion and said partition and the inside of said battery case.

Abstract
In a casing of a headlamp, a substrate portion to which a light-emitting diode as a light source is mounted, and a battery case accommodating a battery for providing necessary power to the light-emitting diode are provided. The substrate portion is spaced apart from a partition disposed on the front side of the battery case, with spacing provided therebetween. The partition is provided with a vent hole, having an upper vent hole and a lower vent hole, for establishing communication of the spacing between the substrate portion and the partition with the space within the battery case, for circulation of the air. Thus, a headlamp capable of suppressing adverse effects of the heat generated from the light-emitting diode or the like on the elements mounted on the substrate is provided.
