Abstract: A light emitting device includes: a base including: a first lead including: a first A surface, a first B surface opposite to the first A surface, and a first C surface located between the first A surface and the first B surface and defining at least one first protrusion, a second lead separated from the first lead, and a resin body covering the first C surface and holding the first lead and the second lead; a light emitting element disposed on the first A surface; and a protecting member disposed continuously on at least a portion of the first A surface and in at least a portion of a gap between the first protrusion and the resin body. In a cross-sectional view, the first protrusion extends from a first end portion of the first A surface at a second lead side toward the second lead.

Abstract: A light emitting device includes a resin package having a rectangular shape in a top view and two short-side lateral surfaces and two long-side lateral surfaces. The two short-side lateral surfaces include a first external surface and a second external surface located on an opposite side from the first external surface. The two long-side lateral surfaces include a third external surface and a fourth external lateral surface located on an opposite side from the third external lateral surface. The lead is not exposed on the third external lateral surface nor the fourth external lateral surface. The first lead is exposed at the first external lateral surface and the second external lateral surface, respectively flush with the resin member at the first external lateral surface and the second external lateral surface. The second lead is exposed at the second external lateral surface, flush with the resin part at the second external lateral surface.

Abstract: A light emitting device includes a resin package including a first lead, a second lead, a resin portion holding the first lead and the second lead, at least one light emitting element mounted on the resin package, and a covering member covering at least a portion of an upper surface of each of the first lead, the second lead, and the resin portion. The resin portion includes at least one resin recess between the first lead and the second lead. At least a portion of the resin recess is located between a first portion of the first lead and a second portion of the second lead in a first direction, and is located between a first extended portion of the first lead and a second extended portion of the second lead in a second direction, and at least a portion of the resin recess is covered by the covering member.

Abstract: A light-emitting device includes: a resin package; and a first light-emitting element and a second light-emitting element. The resin package includes: a resin portion; a first lead having an upper surface and an end surface; a second lead having an upper surface and an end surface; and a recess having lateral surfaces and a bottom surface that includes a portion of the upper surface of the first lead and a portion of the upper surface of the second lead that are exposed from the resin portion. The first light-emitting element and the second light-emitting element are disposed in the recess. The first lead and the second lead are arranged in a first direction. The first light-emitting element and the second light-emitting element are arranged in a second direction perpendicular to the first direction.
