LIGHT-EMITTING DEVICE, ELECTRONIC DEVICE, AND METHOD FOR USING LIGHT-EMITTING DEVICE
A light-emitting device (1) includes: a light source (2) that radiates primary light (6); and a first phosphor (4) that absorbs the primary light (6) and converts the primary light (6) into first wavelength-converted light (7) having a longer wavelength than the primary light (6), the first waveleng...

Summary: | A light-emitting device (1) includes: a light source (2) that radiates primary light (6); and a first phosphor (4) that absorbs the primary light (6) and converts the primary light (6) into first wavelength-converted light (7) having a longer wavelength than the primary light (6), the first wavelength-converted light (7) includes fluorescence based on electron energy transition of Cr3+, a fluorescence spectrum of the first wavelength-converted light (7) has a maximum fluorescence intensity value in region of a wavelength exceeding 710 nm, and the light source (2) is a solid-state light-emitting element in which a rated light output is 1 W or more. |
