Light emitting device and method for manufacturing the same
A light emitting device includes a light transmissive member; a first reflector covering outer peripheral faces of the light transmissive member; a light emitting element disposed under the light transmissive member; a light guiding member covering at least a portion of the light transmissive member, a portion of a lower face of the first reflector, and at least some portions of lateral faces of the light emitting element; and a second reflector covering a portion of the lower face of the first reflector that is exposed from the light guiding member and is located outward of the light guiding member.
1. A light emitting device comprising:
a light transmissive member;
a first reflector covering outer peripheral faces of the light transmissive member;
a light emitting element disposed under the light transmissive member, the light emitting element comprising a plurality of electrodes at a lower face of the light emitting element;
a light guiding member, wherein the light guiding member directly contacts both (i) at least a portion of a lower face of the light transmissive member, and (ii) a portion of a lower face of the first reflector, and wherein the light guiding member covers at least some portions of lateral faces of the light emitting element; and
a second reflector having an upper face that directly contacts a portion of the lower face of the first reflector that is exposed from the light guiding member and is located laterally outward of the light guiding member,
wherein the electrodes of the light emitting element are exposed from a lower face of the second reflector, and
wherein an uppermost face of the light emitting device is formed by an upper face of the light transmissive member and an upper face of the first reflector.
2. The light emitting device according to claim 1 , wherein the light guiding member is substantially free of any wavelength converting substance.
3. The light emitting device according to claim 1 , wherein an exterior of the light guiding member is outwardly oblique from the lateral faces of the light emitting element in an upward direction.
4. The light emitting device according to claim 1 , wherein a width of the light guiding member disposed outward of the light emitting element is in a range of 101% and 200% of a distance between the lateral faces of the light emitting element and an outer edge of the light transmissive member.
5. The light emitting device according to claim 1 , wherein a width of the light guiding member disposed outward of the light emitting element is in a range of 100 μm and 200 μm.
6. The light emitting device according to claim 1 , wherein a thickness of the light transmissive member is in a range of 50 μm and 200 μm.
7. The light emitting device according to claim 1 , wherein the first reflector and the second reflector are made of a resin containing a light reflecting substance.
8. The light emitting device according to claim 1 , wherein the light transmissive member comprises a resin containing a wavelength converting substance.
9. The light emitting device according to claim 1 , wherein at least 80% of a lower face of the light transmissive member is covered by the light guiding member.
10. The light emitting device according to claim 1 , wherein corners of the light transmissive member are exposed from the light guiding member.
11. The light emitting device according to claim 1 , wherein the first reflector is located entirely outward of the light emitting element in a top view of the light emitting device.
