Classification: CPC H | IPC H

Claim 20:
21. A full spectrum camera flash comprising:
a broadband solid-state light source that generates broadband light of dominant wavelength from about 420 nm to about 480 nm and a FWHM from 25 nm to 50 nm;
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;
wherein the broadband light generated by the broadband solid-state light source is composed of a combination of multiple narrowband light emissions, and
wherein the camera flash generates full spectrum white light having a Correlated Color Temperature and an intensity versus wavelength spectrum, which over a wavelength range 460 nm to 600 nm, a maximum percentage deviation between the normalized intensity of the full spectrum white light emitted by the device compared with the normalized intensity of light of a black-body spectrum or CIE Standard Illuminant D of the same Correlated Color Temperature is less than ±30%.
