Abstract:
A full spectrum light emitting device includes photoluminescence materials which generate light with a peak emission wavelength in a range 490 nm to 680 nm (green to red) and a broadband solid-state excitation source operable to generate broadband blue excitation light with a dominant wavelength in a range from 420 nm to 470 nm, where the broadband blue excitation light includes at least two different blue light emissions in a wavelength range 420 nm to 480 nm.
