SOLID-STATE LIGHT-EMITTING ELEMENT, LIGHT-EMITTING DEVICE, AND LIGHTING DEVICE

摘要

PURPOSE: A solid light emitting device, a light emitting device, and a lighting device are provided to improve light extraction efficiency by suppressing light reflection due to the difference of a refractive index. CONSTITUTION: A visible ray is transmitted to a structure(101) with an uneven structure. A material layer(201) with high refractive index is formed on the structure. A light emitting body includes a light emitting area on the material layer. One side of the material layer with high refractive index is flatter than another side thereof in contact with the structure. The refractive index of the material layer is 1.6 or greater. The refractive index of the structure is between 1.0 and the refractive index of the material layer.
