Abstract

The present invention discloses a semiconductor light emitting device comprising at least one semiconductor light emitting element of edge-emission type, a first heat sink and a second heat sink, wherein at least a part of an electrode for the first-conduction-type semiconductor of the semiconductor light emitting element is in contact with the first heat sink; at least a part of an electrode for the second-conduction-type semiconductor of the semiconductor light emitting element is in contact with the second heat sink; and the first heat sink and the second heat sink are in contact with each other in a junction overlooking one of the two side planes which do not compose the facets of the cavity in the semiconductor light emitting element. The semiconductor light emitting device of the present invention is characterized by having excellent heat spreading, allowing easy and reproducible assembling even if the components or the element composing the semiconductor light emitting device have dimensional errors, and allowing simple optical coupling with an optical fiber or the like.
