Abstract:
Provided is a light emitting device having a high light emitting efficiency and a good brightness distribution, further having a good color mixing and a good light distribution. A light emitting device includes a base member, a plurality of light emitting elements disposed on the base member, and a sealing member sealing the light emitting elements. The base member has a plurality of regions divided by virtual lines extending in a radial manner from one point disposed on the base member to an outer periphery of the base member, and a light transmissive wall member between adjacent two regions of the plurality of regions. A sealing member containing a fluorescent material is disposed on each region of the plurality of regions. A color tone of light emitted from a first region which is one of the two adjacent regions of the plurality of regions differs from a color tone of light emitted from a second region which is the other of the two adjacent regions.
