摘要： A lighting apparatus for emitting white light including a semiconductor light source emitting radiation with a peak at from about 250 nm to about 500 nm; a first phosphor having a peak emission between about 450 and 550 nm; and a second phosphor having a peak emission between about 615 and 670 nm; wherein the overall emission spectrum of the lighting apparatus has a depression between about 550 and 615 nm, said depression extending to between about 5% and 25% of the highest intensity of the emission spectrum of the lighting apparatus in the region from 400 to 700 nm. In this apparatus, the red-green color contrast is increased versus the referent illuminant.
