<P>PROBLEM TO BE SOLVED: To provide a light-emitting device which includes directly emitted light from the top face of a light-emitting element and reflected light of a side surface light of the light-emitting element and which can easily equalize light intensity distribution. <P>SOLUTION: The light-emitting device according to an embodiment comprises: a light-emitting element; a light reflection body; and an encapsulation resin layer. The light-emitting element has a first main surface and a side surface, and has an optical axis of directly emitted light in a direction perpendicular to the first main surface. The light reflection body has a light reflection surface which can reflect the light emitted from the side surface of the light-emitting element. The encapsulation resin layer covers the light-emitting element and the light reflection surface. Also, the encapsulation resin layer includes an envelope which is created by moving a first curved surface having a vertex on the optical axis and convex-shaped toward the light emitting side and a second curved surface passing along the light reflection surface, having a vertex on a straight line parallel to the optical axis, and convex-shaped toward the light emitting side in such a way that the straight line passes along the light emitting surface. <P>COPYRIGHT: (C)2012,JPO&INPIT |
