Claim 0:
1. A light emitting device, comprising:
a package for surface mounting, the package comprising a plurality of leads and a first dark-colored resin securing at least some of the plurality of leads, three leads of the plurality of leads respectively including an exposed region exposed from the first dark-colored resin at a primary surface of the package, with a first recess, a second recess, and a third recess each being defined in the exposed region of a respective one of the three leads; the light emitting device further comprising
a plurality of light emitting elements, including a first light emitting element disposed in the first recess and configured to emit first light, a second light emitting element disposed in the second recess and configured to emit second light having a wavelength shorter than a wavelength of the first light, and a third light emitting element disposed in the third recess and configured to emit third light having a wavelength shorter than a wavelength of the second light;
a first colored resin member disposed in the first recess and colored in a similar color as the first light;
a second colored resin member disposed in the second recess and colored in a similar color as the second light;
a third colored resin member disposed in the third recess and colored in a similar color as the third light; and
a mold resin including a light-transmissive base material and sealing the plurality of light emitting elements,
wherein in a plan view, at least a portion of the first colored resin member is positioned around the first light emitting element in the first recess, at least a portion of the second colored resin member is positioned around the second light emitting element in the second recess, and at least a portion of the third colored resin member is positioned around the third light emitting element in the third recess,
wherein the mold resin includes a base portion covering the primary surface of the package and the plurality of light emitting elements, and a plurality of lens portions formed integrally with the base portion,
each of the plurality of lens portions having a convex shape protruding upwardly from the base portion, and
wherein, in a plan view, the plurality of lens portions include a first lens portion overlapping with the first recess, the first light emitting element, and the first colored resin member, a second lens portion overlapping with the second recess, the second light emitting element, and the second colored resin member, and a third lens portion overlapping with the third recess, the third light emitting element, and the third colored resin member.
