LIGHT EMITTING DEVICE CAPABLE OF IMPROVING LIGHT EXTRACTION EFFICIENCY, A LIGHT EMITTING DEVICE MANUFACTURING METHOD, A LIGHT EMITTING DEVICE PACKAGE, AND A LIGHTING SYSTEM

摘要

PURPOSE: A light emitting device, a light emitting device manufacturing method, a light emitting device package, and a lighting system are provided to arrange a plurality of recesses in the upper region of a light emitting structure, thereby effectively emitting light through the upper surface of the light emitting structure.;CONSTITUTION: A reflecting layer(157) is arranged on a conductive supporting member(160). A protection member(155) is arranged in a circumferential region of the conductive supporting member. A light emitting structure(145) is arranged on the protection member. The light emitting structure comprises a first conductive type semiconductor layer(130), an active layer(140), and a second conductive semiconductor layer(150). A recess(165) is arranged in the upper region of the light emitting structure.;COPYRIGHT KIPO 2012
