Abstract:
1. A semiconductor light emitting device comprising: a light emitting element array formed in such a manner that a plurality of light emitting elements are connected in series, each of the plurality of light emitting elements including: (a) a multilayer epitaxial structure including a first conductive layer, a second conductive layer and a light emitting layer between the first conductive layer and the second conductive layer, a main surface of the second conductive layer which faces away from the light emitting layer being a light extraction surface, (b) a first electrode formed on a main surface of the first conductive layer which faces away from the light emitting layer, and (c) a second electrode formed on the main surface of the second conductive layer which faces away from the light emitting layer, the first electrode and the second electrode are positioned relative to each other in a same manner for each light emitting element; a metal layer on which the light emitting element array is formed, with an insulating layer therebetween, in such a manner that the first electrode is positioned closer to the metal layer than the second electrode, the metal layer connecting and supporting the multilayer epitaxial structures and conducting heat generated in the light emitting layer, wherein the metal layer is electrically divided into at least two portions; the insulating layer is formed on side surfaces of each light emitting element; a first conductor bridging member is connected to the first electrode of a light emitting element at one end of the light emitting element array and to one of the two portions of the metal layer to form a first power supply terminal; and a second conductor bridging member is connected to the second electrode of a light emitting element at the other end of the light emitting array and to the other of the two portions of the metal layer to form a second power supply terminal.
