Claim:
1. A light emitting device comprising: a molded material including an opening through which light generated from a light emitting element disposed in the molded material is emitted; a projecting support disposed along at least part of a circumference of the opening of the molded material; a lens including an inner surface that defines an internal surface on which the light emitted from the light emitting element is incident, an outer surface that defines an external surface from which the incident light is emitted to the outside, and a bottom surface that connects the inner surface and the outer surface, wherein a boundary between the inner surface and the bottom surface contacts the projecting support, or a lower part of the inner surface contacts the projecting support, or the bottom surface contacts the projecting support; and a lead frame on which the light emitting element is mounted and includes a first lead and a second lead spaced apart from each other, wherein an upper part of the opening of the molded material includes a circular shape, and a lower part of the opening of the molded material includes a rectangular shape disposed in a footprint of the circular shape, wherein the molded material is bonded to the lead frame such that part of a top surface of the first lead and part of a top surface of the second lead are exposed to an area defined by the rectangular shape, wherein the rectangular shape includes four sides that are not parallel to one direction along which a lead separation region between the first and second leads extends, wherein a convergence point of two sides that converge on the first lead among the four sides is connected to a first curve projecting in a direction away from the lead separation region, and wherein a convergence point of two sides that converge on the second lead among the four sides is connected to a second curve projecting in a direction away from the lead separation region.
