Abstract
A light-emitting device includes a substrate having a front surface on which a semiconductor light-emitting element is mounted. A front cover is provided which thermally contacts the front surface of the substrate at a periphery of the semiconductor light-emitting element and is disposed on a front side of the substrate. A heat conduction path is formed along which heat generated by the semiconductor light-emitting element is conducted in order of the substrate and the front cover and the heat is radiated from a front surface of the front cover, so that a heat radiation property from a front surface of the light-emitting device is improved.
