  • Patent number: 9465154
    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.
