LIGHT EMITTING DEVICE
First Claim
1. A light emitting device comprising:
- a mounting board;
a plurality of light sources arranged on the mounting board;
a light diffuser arranged above the plurality of light sources;
a wavelength conversion layer located at least between the light sources and the light diffuser, the wavelength conversion layer being configured to absorb at least a portion of light from the light sources and to emit light having a wavelength which is different from a wavelength of the light from the light sources;
a plurality of scatter reflection portions arranged on a surface of the wavelength conversion layer that is closer to the light diffuser, each of the scatter reflection portions being arranged above at least a portion of an upper face of a corresponding one of the light sources, each of the scatter reflection portions containing particles of reflective material, and each of the scatter reflection portions having a single-layered or multi-layered structure in a cross-sectional view; and
a partitioning member that is light-reflective, the partitioning member includingwalls defining a plurality of regions and surrounding each of the light sources on the mounting board, with each of the walls having an apex in a cross section, andplanar bottoms extending in parallel with a surface of the mounting board from bottom parts of the walls toward a corresponding one of the light sources, whereineach of the planar bottoms of the partitioning member defines a through hole in which the corresponding one of the light sources is located.

Abstract
A light emitting device includes a mounting board, light sources, a light diffuser, a wavelength conversion layer, and scatter reflection portions. Each of the light sources has an upper face on which a light reflecting layer is disposed. The light diffuser is arranged above the plurality of light sources. The wavelength conversion layer is located at least between the light sources and the light diffuser. The wavelength conversion layer is configured to absorb at least a portion of light from the light sources and to emit light having a wavelength which is different from a wavelength of the light from the light sources. The scatter reflection portions are arranged on a surface of the wavelength conversion layer that is closer to the light diffuser. Each of the scatter reflection portions is arranged above at least a portion of the upper face of a corresponding one of the light sources.
