摘要：
A green-shifted red solid state lighting device includes at least one green solid state light emitter arranged to stimulate emissions from at least one red lumiphor, arranged in combination with at least one blue solid state light emitter. Such device may be devoid of any yellow lumiphor arranged to be stimulated by a blue solid state light emitter. A green shifted red plus blue (GSR+B) lighting device exhibits reduced Stokes Shift losses as compared to a blue shifted yellow plus red (BSY+R) lighting device, with comparable color rendering performance and similar efficiency, enhanced color stability over a range of operating temperatures, and enhanced color rendering performance at higher correlated color temperatures. Additional solid state emitters and/or lumiphors may be provided.
