ABSTRACT:
A light-emitting semiconductor device is provided having a light-emitting semiconductor element emitting light in two directions. The light-emitting element is disposed in a housing so that one light-emitting face of the semiconductor element adjacent a heat sink, and a light guide is arranged to confront the other light-emitting face of the semiconductor element and to guide light from said other light-emitting face to the outside of the housing. In this device, the end face of the light guide confronting said other light-emitting face of the semiconductor element includes a face substantially inclined to the optical axis of light emitted from the semiconductor element.
