Patent ID: 8431949

Claim:
A light emitting device, comprising: a semiconductor light emitting element; a first lead including an element mount portion on which the semiconductor light emitting element is mounted; a second lead electrically connected to the semiconductor light emitting element; and a resin package covering the semiconductor light emitting element and part of each of the first and the second leads, the resin package including a lens portion facing the semiconductor light emitting element and a bottom surface opposite to the lens portion; wherein the first lead includes a pair of first standing portions and a pair of first terminal portions, the first standing portions being spaced from each other with the element mount portion intervening therebetween, the first terminal portions extending from the first standing portions in opposite directions and in a direction in which the first standing portions are spaced from each other, and wherein each of the first standing portions projects from the bottom surface of the resin package in a direction away from the lens portion, and each of the first terminal portions is spaced apart from the bottom surface of the resin package and extends in parallel to the bottom surface of the resin package, wherein the second lead includes a pair of second standing portions and a pair of second terminal portions, the second terminal portions extending from the second standing portions in opposite directions, each of the second standing portions projecting from the bottom surface of the resin package in a direction away from the lens portion, each of the second terminal portions extending in parallel to the bottom surface of the resin package, wherein the first terminals and the second terminal portions are flush with each other so as to extend along and in contact with a common plane, and wherein one of the first terminal portions and the second terminal portions is different in width from the other three terminal portions.
