Abstract
A integrated light-emitting device includes: a base including a conductive wiring; a plurality of light-emitting devices mounted on the base and configured to emit a first light, each of the light-emitting devices comprising a light-emitting element and a encapsulant covering the light-emitting element; a light reflective film provided on an upper surface of the light-emitting element; and a plurality of light reflective members disposed between adjacent ones of the light-emitting devices. A ratio (H/W) of a height (H) of the encapsulant to a width (W) of a bottom surface of the encapsulant is less than 0.5. Each of the light-emitting devices has a batwing light distribution characteristics.
Claims16
An integrated light-emitting device comprising:
- a base;
- a plurality of light-emitting devices mounted on a surface of the base, each of the light-emitting devices comprising:
- a light-emitting element,
- a light reflective film located on an upper surface of the light-emitting element that faces away from the surface of the base, and
- an encapsulant that covers the light-emitting element and the light reflective film so as to directly contact an upper surface of the light reflective film, lateral surfaces of the light reflective film, and lateral surfaces of the light-emitting element, the encapsulant having a dome shape, wherein the encapsulant has a maximum height at a position that overlaps the light-emitting element in a top view;
- and
- a plurality of light reflective members disposed between adjacent ones of the light-emitting devices, wherein the light reflective members divide a surface of the base into a plurality of pixels.
A light-emitting module comprising:
- a base having an upper surface;
- a plate disposed on the upper surface of the base, the plate comprising a plurality of light reflective surfaces that divide the base into a plurality of regions in a top view;
- and
- a plurality of light-emitting devices, each disposed on an upper surface of the base in a respective one of the regions, each light-emitting device comprising:
- a light-emitting element,
- a light reflective film disposed on an upper surface of the light emitting element, and
- an encapsulant that covers the light-emitting element and the light reflective film so as to directly contact an upper surface of the light reflective film, lateral surfaces of the light reflective film, and lateral surfaces of the light-emitting element, the encapsulant having a dome shape, wherein the encapsulant has a maximum height at a position that overlaps the light-emitting element in a top view.
