摘要:
A light emitting device is configured to achieve a white color by mixing light from respective phosphors. The light emitting device includes: a light emitting element for emitting ultraviolet or short-wavelength visible light having a peak wavelength in a wavelength range of 380 to 420 nm; a first phosphor excited by the ultraviolet or short-wavelength visible light to emit visible light having a peak wavelength in a wavelength range of 560 nm to 600 nm; a second phosphor excited by the ultraviolet or short-wavelength visible light to emit visible light having a complementary relationship with visible light emitted by the first phosphor; and a light transmitting member which is a light transmitting layer for covering the light emitting element, and has the first phosphor and the second phosphor dispersed therein.
