Classification: CPC H | IPC H

Claim 0:
1. A full spectrum white light emitting device comprising:
a broadband LED flip chip that generates broadband light of dominant wavelength from about 420 nm to about 480 nm and a FWHM from 25 nm to 50 nm; and
at least one photoluminescence layer covering a light emitting face of the broadband LED flip chip;
wherein the broadband LED flip chip comprises a broadband InGaN/GaN multiple quantum wells LED chip comprising multiple different wavelength quantum wells in its active region that generate multiple narrowband light emissions of multiple different wavelengths and wherein broadband light generated by the broadband LED flip chip is composed of a combination of the multiple narrowband light emissions, and
wherein the at least one photoluminescence material layer comprises a first photoluminescence material which generates light with a peak emission wavelength from 490 nm to 550 nm; and a second photoluminescence material which generates light with a peak emission wavelength from 600 nm to 680 nm.
