发明名称 High CRI lighting device with added long-wavelength blue color
摘要 Solid state lighting devices include least one solid state emitter and multiple lumiphors, arranged to output aggregated emissions comprising at least one short wavelength blue peak, at least one long wavelength blue (LWB) peak, at least one yellow and/or green peak, and at least one red and/or orange peak. Presence of long wavelength blue enhances color rendering. At least one solid state emitter may include a short wavelength blue LED, LWB LED, and/or UV LED. Multiple emitters may be provided. Resulting devices may provide CRI greater than 85, efficiency of greater than 50 lm/watt, and color stability in a range of Deltau'v'@0.008 over a temperature change of 75° C.
