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 11):
The light emitting device according to  claim 1 , wherein intensity of the peak wavelength of the light spectrum of the secondary light emitted by the second phosphor accounts for not less than 25% and not more than 50% of a total of (i) an intensity of the peak wavelength of the light spectrum of the secondary light emitted by the first phosphor and (ii) an intensity of the peak wavelength of the light spectrum of the secondary light emitted by the second phosphor.
