Abstract: To provide a light emitting device that makes it possible to form a surface light emitting apparatus of less unevenness in luminance. The light emitting device 10 of the present invention comprises a light emitting element 30, connecting terminals 21a, 21b connected with the light emitting element 30, a package 12 which has a recess 40 wherein the light emitting element 30 is mounted and from which a part of each connecting terminal 21a, 21b is projected outward, an opening 41 of the recess 40 being elongated in one direction, wherein both side walls of the recess 40 positioned in the longitudinal direction of the recess 40 are inclined surface 43, an angle ? between both the inclined surfaces 43 being 90 degrees or more. In the light emitting device 10 of the present invention, light emitted by the light emitting element 30 is spread sufficiently in the longitudinal direction of the opening 41 so as to produce a band-shaped beam.

Abstract: Disclosed are a light emitting device and a lighting system having the same. The light emitting device includes a body including first and second lateral side parts, third and fourth lateral side parts, and a cavity, a first lead frame extending in a direction of the first lateral side part of the body, a second lead frame extending in a direction of the second lateral side part of the body, a gap part between the first and second lead frames, and a molding member in the cavity. The first lead frame includes a first recess part having a first depth, and a second recess part recessed at a second depth in a region adjacent to the first lateral side part of the body, and the first depth of the first recess part is different from the second depth of the second recess part.
