Abstract
A light-emitting diode chip configured to emit light of a first wavelength range and light of a second wavelength range, including a substrate, a light-emitting structure disposed on a first surface of the substrate, the light-emitting structure including an active layer disposed between a first conductivity-type semiconductor layer and a second conductivity-type semiconductor layer, and configured to emit light of the first wavelength range, and first and second distributed Bragg reflectors (DBRs) disposed on a second surface of the substrate. The first DBR is disposed closer to the substrate than the second DBR, the first wavelength range comprises a blue wavelength range, the first DBR comprises a higher reflectivity for light of the second wavelength range than for light of the first wavelength range, and the second DBR comprises a higher reflectivity for light of the first wavelength range than for light of the second wavelength range.
