摘要：A conversion LED with a chip which emits primary blue radiation, and a layercontaining luminescent substance upstream of the chip which converts at least part ofthe primary radiation of the chip into secondary radiation, wherein a first garnetA3B5O12:Ce yellow-green emitting luminescent substance and a second nitride silicateM2X5Y8:D orange-red emitting luminescent substance is used, wherein the peakwavelength of the primary radiation is in the range of 430 to 450 nm, in particular of upto 445 nm, while the first luminescent substance is a garnet with the cation A=Lu or amixture of Lu, Y with up a Y fraction of up to 30%, and wherein B has fractions of both Aland Ga, while the second luminescent substance is a nitride silicate which contains both Baand Sr as cation M, and in which the doping consists of Eu, wherein the second
luminescent substance contains 35 to 75 mol.-% Ba for the component M, remainder is Sr,where X=Si and Y=N.
