Abstract:
1. A light emitting device, comprising: a light emitting element; and a package body in which said light emitting element is contained and a concave portion is formed, the concave portion having a bottom surface on which said light emitting element is disposed and being filled with a transparent sealing resin for covering said light emitting element, the sealing resin having with air a boundary serving as an emitting surface, from which light is extracted, said light emitting element including an active layer formed at a position between a substantially center part of said light emitting element and a bottom surface of said light emitting element and emitting light so as to achieve, as an emission characteristic, a strong peak intensity at an emission angle with respect to a line normal to said light emitting element in a range from 40° to 60°, and the concave portion having a reflection surface including a gentle slope surface and a steep slope surface steeper than the gentle slope surface, which are provided in this order from the bottom surface of the concave portion.
