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.

Abstract: A light-emitting device includes an inner light-emitting element having an n-sided polygonal shape (n is an integer of 3 or more) in a plan view with a peak emission wavelength in a range of 490 nm to 570 nm; m (m is an integer of 3 or more) outer light-emitting elements with a peak emission wavelength of 430 nm or greater and less than 490 nm; and a first phosphor with a peak emission wavelength in a range of 580 nm to 680 nm covering the inner light-emitting element and the m outer light-emitting elements. Each of n lateral surfaces of the inner light-emitting element faces a corresponding one of the m outer light-emitting elements in a top view.

Abstract: A 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 disposed opposite the first lead, 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. In a top view, the upper surface of the first lead includes a first groove overlapping a first side of the bottom surface, a second groove overlapping a second side of the bottom surface, a third groove overlapping a third side of the bottom surface, and one or more fourth grooves extending from a portion of the third groove to an end surface of the first lead facing the second lead.
