Abstract
A light emitting device comprises a plurality of light emitting elements sealed with a fluorescent material containing member, each of the plurality of light emitting elements having an upper surface. The plurality of light emitting elements are arranged such that, in a planar view of a light emitting surface, when the plurality of light emitting elements are projected in a parallel direction in a plane of the light emitting surface, traces of the upper surfaces of the plurality of the light emitting elements merge into a single trace. A light emitting apparatus comprises a light-concentrating device, and the light emitting device.
Claims22
A light emitting device comprising:
- a plurality of light emitting elements sealed with a single fluorescent material containing member, each of the plurality of light emitting elements having an upper surface,
- wherein the plurality of light emitting elements are arranged such that, in a planar view of a light emitting surface, when the plurality of light emitting elements are projected in any parallel direction in a plane of the light emitting surface, traces of the upper surfaces of the plurality of the light emitting elements merge into a single trace.
A lighting apparatus comprising:
- a light-concentrating device;
- and
- a light emitting device comprising:
- a plurality of light emitting elements sealed with a single fluorescent material containing member, each of the plurality of light emitting elements having an upper surface,
- wherein the plurality of light emitting elements are arranged such that, in a planar view of a light emitting surface, when the plurality of light emitting elements are projected in any parallel direction in a plane of the light emitting surface, traces of the upper surfaces of the plurality of the light emitting elements merge into a single trace, wherein the light emitting device is attached to the light-concentrating device.
A light emitting device comprising:
- a plurality of light emitting elements sealed with a single fluorescent material containing member, each of the plurality of light emitting elements having an upper surface,
- wherein the plurality of light emitting elements are arranged such that, in a planar view of a light emitting surface, when the plurality of light emitting elements are projected in any parallel direction in a plane of the light emitting surface, traces of the upper surfaces of the plurality of the light emitting elements merge into a single trace,
- wherein the plurality of light emitting elements are arranged such that, in a planar view of the light emitting surface, when the plurality of the light emitting elements are rotated around a center of the light emitting surface, traces of the upper surfaces of the plurality of the light emitting elements merge to form a single circle centered at the center of the light emitting surface, and
- wherein, in a planar view of the light emitting surface, the plurality of the light emitting elements are arranged more densely at a center region of the light emitting surface than at a peripheral region of the light emitting surface.
