Abstract:
1. A light-emitting diode lamp comprising: at least one light-emitting diode element having electrode terminals; a conductive heat-receiving member, electrically and mechanically connected with said electrode terminals of said at least one light-emitting diode element, for receiving heat emitted from said at least one light-emitting diode element via said electrode terminals; a casing for housing, at substantially sealed state, said at least one light-emitting diode element and said heat-receiving member; a plurality of fins thermally coupled with said casing and arranged at a position out of a main irradiation direction of light from said at least one light-emitting diode element; and a conductive heat-transfer member electrically and mechanically connected with said heat-receiving member, said heat-transfer member extending to a position at which said plurality of fins exist, said plurality of fins being formed on an inner wall of a heat-collection fin member with an outer wall kept in contact with an inner wall of said casing, said heat-collection fin member being made of a translucent resin material.
