Title:
LIGHT EMITTING DEVICE AND ILLUMINATION APPARATUS
Document Type and Number:
WIPO Patent Application WO/2019/164014
Kind Code:
A1
Abstract:
A light emitting device according to an embodiment of the present invention is provided with: a light emitting element; a first fluorescent body; and a second fluorescent body. The first fluorescent body radiates light having a first peak wavelength in a wavelength range of 400-480 nm in response to light emitted from the light emitting element. The second fluorescent body radiates light having a second peak wavelength in a wavelength range of 480-600 nm in response to the light emitted from the light emitting element. The light emitting element radiates light of 280-315 nm which has a third peak wavelength in a wavelength range of 280-315 nm.
