Patent number: 11211532Abstract: 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.Type: GrantFiled: December 21, 2017Date of Patent: December 28, 2021Assignee: NICHIA CORPORATIONInventors: Atsushi Yamamoto, Keiko Ono
