Document Type and Number:
WIPO Patent Application WO/2021/075394
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a light emitting device that can emit white light, and that is configured such that the manufacturing cost for a wavelength conversion member can be suppressed. A light emitting device (1) according to the present invention comprises a light emitting element (2) and a wavelength conversion sheet (3) disposed on the light-radiating side of the light emitting element, the light emitting device being characterized in that: the light emitting element is adjusted so as to be able to produce colored light resulting from mixing non-blue visible light with blue light; the wavelength conversion member includes red fluorescent particles and green fluorescent particles; and light from the light emitting element is emitted as white light via the wavelength conversion member.
