Light emitting device having heat dissipation terminal arranged on substrate
First Claim
1. A light emitting device comprising:
- a substrate having a first main surface, a second main surface that is opposite from the first main surface, and a mounting surface that is adjacent to at least the second main surface, the substrate including an insulating base material which has a concave portion with an inner curved surface and a pair of connection terminals;
a light emitting element mounted on the first main surface of the substrate;
a sealing member that is in contact with at least a part of a side surface of the light emitting element and is formed substantially in the same plane as the substrate on the mounting surface;
a light transmissive member that covers an upper surface of the light emitting element and a part of an upper surface of the sealing member, side surfaces of the light transmissive member being covered with the sealing member; and
a heat dissipation terminal that is arranged generally in the center on the second main surface of the substrate and that has a recess portion as viewed along a direction normal to the second main surface.

Abstract
A light emitting device includes a substrate, a light emitting element, a sealing member, a light transmissive member and a heat dissipation terminal. The substrate includes an insulating base material which has a concave portion with an inner curved surface. The sealing member is in contact with at least a part of a side surface of the light emitting element and is formed substantially in the same plane as the substrate on a mounting surface. The light transmissive member covers an upper surface of the light emitting element and a part of an upper surface of the sealing member, side surfaces of the light transmissive member being covered with the sealing member. The heat dissipation terminal is arranged generally in the center on a second main surface of the substrate and that has a recess portion as viewed along a direction normal to the second main surface.
