SEMICONDUCTOR LIGHT EMITTING DEVICE

摘要

PURPOSE: A semiconductor light emitting device is provided to improve luminous efficiency by preventing the absorption of light by a conductive board and reflecting the light which is income to the conductive board. CONSTITUTION: A light emitting structure is formed on the upper side of a conductive board. The light emitting structure comprises a first electrical conduction semiconductor layer, an active layer, and a second electrical conduction semiconductor layer(30). A second conductive type electrode(80) is formed on the second electrical conduction semiconductor layer. A reflective film(90) is included according to the side of the conductive board. A reflective metal layer is formed between the conductive board and the first electrical conduction semiconductor layer.
