Patent ID: 8022420

Claim:
A semiconductor light emitting device comprising: a base substrate including an insulating substrate and a plurality of conductive patterns disposed on one main surface of the insulating substrate; and three light emitting elements each having a rhombus shape with interior angles of approximately 60° and approximately 120° in plan view, each light emitting element including (i) a semiconductor multilayer structure with a light emission layer, (ii) a first electrode disposed in contact with a first main surface of the semiconductor multilayer structure, and (iii) a second electrode disposed along an edge of a second main surface of the semiconductor multilayer structure to establish electrical connection with the second main surface, wherein the three light emitting elements are arranged on one main surface of the base substrate having the conductive patterns disposed thereon with the first and second electrodes facing toward the base substrate, so as to together form a substantially regular hexagonal shape in plan view, in each light emitting element, the first electrode is electrically connected to one of the conductive patterns via a bonding layer, and the second electrode is electrically connected to another one of the conductive patterns via a metal film disposed along a side surface of the semiconductor multilayer structure so that an insulating film is sandwiched between the metal film and the side surface, and a phosphor is disposed to adherently cover the three light emitting elements, wherein the phosphor has a low profile and substantially regular hexagonal shape having a center substantially coinciding with a center of the substantially regular hexagonal shape formed by the three light emitting elements.
