Abstract:
A light emitting device which emits a secondary light with high color purity and has a fast response speed is obtained. A KSF phosphor ( 15 ) which absorbs a part of blue light and emits red light and a CASN phosphor ( 16 ) are distributed in a resin ( 14 ) which seals an LED chip ( 13 ) which emits the blue light. The KSF phosphor ( 15 ) absorbs the blue light and emits the red light by forbidden transition, and the CASN phosphor ( 16 ) absorbs the blue light and emits the red light by allowed transition.

Claim (Index 1):
A light emitting device comprising:\n a light emitting element which emits primary light; a resin which seals the light emitting element; and a first phosphor and a second phosphor that absorb a portion of the primary light, and emit secondary light having a wavelength longer than that of the primary light, wherein the first phosphor absorbs the primary light and emits the secondary light by forbidden transition, the second phosphor absorbs the primary light and emits the secondary light by allowed transition, a wavelength width of a peak wavelength of a light spectrum of the secondary light emitted by the first phosphor is narrower than that of a peak wavelength of a light spectrum of the secondary light emitted by the second phosphor, and a response speed of the second phosphor is faster than that of the first phosphor.
