Abstract:
1. A light emitting apparatus, comprising: a solid-state light emitting element; a power supply member that supplies power to the solid-state light emitting element; a reflection section that is disposed opposite to a light extraction surface of the solid-state light emitting element to reflect light emitted from the solid-state light emitting element a heat radiation member that is disposed with a heat radiation width in a back direction of the solid-state light emitting element; an insulating layer disposed between the power supply member and the heat radiation member; and a case in which the reflection section and the heat radiation member are placed and which externally radiates heat to be transferred from the heat radiation member, wherein the case is integrated with the heat radiation member, the case comprises an inner wall surface with a high reflectivity, and the case has a high heat conductivity, and wherein the heat radiation member comprises a planar member disposed parallel to a light extraction direction of the light emitting apparatus, the power supply member, which is separate from said heat radiation member, is secured to an end face of the planar member, the solid-state light emitting element is mounted on the end face of the planar member, and the planar member is disposed parallel to a longitudinal direction of the power supply member, wherein the power supply member and the planar member both comprise a light reflective surface.
