Abstract
A light emitting device includes a plurality of light emitting elements and a package. The package includes two metal parts on which the plurality of light emitting elements are disposed, and a resin body securing the two metal parts. The resin body has four sides and four connecting parts alternately connected to one another in a top view. Two subsequent sides are perpendicular to each other. Each of the two metal parts includes a die-pad on which one or more of the plurality of light emitting elements are disposed, and two extending portions extending from the die-pad. An end portion of each of the two extending portions is extended laterally outward from a respective one of the connecting parts of the resin body, and the end portion of each of the two extending portions is located inward of virtual extension lines of corresponding two sides of the resin body.
