Document Type and Number:
WIPO Patent Application WO/2024/058548
Kind Code:
A1
Abstract:
Provided are a light-emitting element and a lighting fixture having same. A light-emitting element according to one embodiment comprises: a first light-emitting diode chip emitting light having a first peak wavelength; a second light-emitting diode chip emitting light having a second peak wavelength longer than the first peak wavelength; a first wavelength conversion material that is disposed on the first light-emitting diode chip and converts the wavelength of the light emitted from the first light-emitting diode chip; and a second wavelength conversion material that is disposed on the second light-emitting diode chip and converts the wavelength of the light emitted from the second light-emitting diode chip. The peak wavelength of the excitation spectrum of the first wavelength conversion material is closer to a first peak wavelength than a second peak wavelength, and the peak wavelength of the excitation spectrum of the second wavelength conversion material is closer to the second peak wavelength than the first peak wavelength. Light that travels from the first light-emitting diode chip to the second wavelength conversion material is blocked, and light that travels from the second light-emitting diode chip to the first wavelength conversion material is blocked.
