    Abstract: A light emitting device includes: a resin package including: a plurality of leads that includes: a first lead, and a second lead, a first resin portion, a second resin portion, and a third resin portion, the leads and the at least one inner lateral wall surface of the first resin portion defining a recess, the third resin portion being located between the first lead and the second lead, the second resin portion disposed surrounding an element mounting region at the bottom of the recess; and at least one light emitting element disposed on an element mounting region. At least one inner lateral wall surface of the recess has at least one protruding portion that protrudes toward the at least one light emitting element. A region of the recess between the at least one inner lateral wall surface and the second resin portion is covered by a light-reflective member.

    Abstract: A package includes a resin molded body having a side wall provided between a first side and a second side to surround a recess portion which has a bottom portion on the second side. The bottom portion of the recess portion includes an element mount region provided in a vicinity of the side wall and a wire connection region separated from the element mount region. The element mount region has a polygonal outer peripheral shape having corners and diagonals connecting two of the corners when viewed in the height direction. An area of the wire connection region is smaller than an area of the element mount region when viewed in the height direction. The wire connection region is provided on an extension of one of the diagonals passing through one of the corners of the element mount region to face toward the adjacent to one of the corners.

    Abstract: A package includes a resin molded body, a first lead electrode, a second lead electrode, and a recess portion. The recess portion is provided on a first side of the resin molded body and a light-emitting element is to be provided in the recess portion. The recess portion includes a bottom portion, a top portion, and a side wall. The bottom portion includes an element mount region and a wire connection region. An upper surface of the first lead electrode is exposed from the resin molded body in the element mount region and the element mount region has an outer peripheral shape in accordance with an outer peripheral shape of the light-emitting element when viewed in a height direction. The wire connection region is provided adjacent to the element mount region and is smaller than the element mount region.

    Abstract: A light emitting device includes a resin package having a recess defined by a recess bottom surface and a recess lateral surface. The resin package includes a first lead including a first lead lower surface, a first lead upper surface, and an end portion. The light emitting element is mounted on the first lead upper surface opposite to the first lead lower surface. The light reflecting member is disposed on the recess bottom surface between the recess lateral surface and the light emitting element in a lateral direction. The end portion is provided between the first lead lower surface and the light reflecting member in the lateral direction. The end portion has a cross-sectional area viewed in the lateral direction which is smaller than a cross-sectional area of the first lead between the first lead lower surface and the first lead upper surface viewed in the lateral direction.
