Patent ID: 8759866

Claim:
A light emitting device comprising: a light emitting element; connecting terminals connected with the light emitting element, the connecting terminals having external terminals; a package which has a recess wherein the light emitting element is mounted and from which a part of each connecting terminal is projected outward, an opening of the recess being elongated in one direction in a light emitting surface of the package, the package further having an outer back surface which is on an opposite side from the light emitting surface of the package, and wherein the package is made from a material different from the material of which said connecting terminals are made, wherein both side walls of the recess positioned in the longitudinal direction of the recess are inclined surface, an angle θ between both the inclined surfaces being in a range from 135 to 165 degrees, the package has one or more notches formed in an outer surface of the package between said outer back surface and an outer side surface of the package, the external terminals are arranged in the one or more notches, and disposed inwardly from said outer back surface of the package, so that, for each of the external terminals: an outer back surface of the external terminal that is farthest from the light emitting surface of the package is on an opposite side from the light emitting surface of the package, and along a direction perpendicular to the light emitting surface of the package, said outer back surface of the external terminal is disposed at a distance from the light emitting surface of the package that is shorter than the distance between the light emitting surface of the package and said outer back surface of the package, and the external terminals are also disposed inwardly from the outer side surface of the package.
