Abstract:
A light-emitting device 1 according to the present invention includes: a solid-state light-emitting element 10 that radiates laser light; and a wavelength converter 50 including plural types of phosphors which receive the laser light and radiate light. The phosphors included in the wavelength converter 50 are substantially composed of Ce3+-activated phosphors. The above-described light-emitting device includes at least a warm-color Ce3+-activated phosphor that receives the laser light and radiates light having a light emission peak within a wavelength range of 580 nm or more to less than 660 nm, and light-emitting components radiated by the phosphors are composed of only light-emitting components derived from Ce3+.
