Abstract: Conversion LED emits primary radiation (peak wavelength 435 nm to 455 nm) and has a luminescent substance-containing layer positioned to intercept the primary radiation and convert it into secondary radiation. First and second luminescent substances are used. The first luminescent substance is a A3B5O12:Ce garnet type emitting yellow green having cation A=75 to 100 mol. % Lu, remainder Y and a Ce content of 1.5 to 2.9 mol. %, where B=10 to 40 mol. % Ga, remainder Al. The second luminescent substance is of the MAlSiN3:Eu calsine type which emits orange red, where M is Ca alone or at least 80% Ca and the remainder of M may be Sr, Ba, Mg, Li or Cu, in each case alone or in combination, wherein some of the Al up to 20%, can be replaced by B, and wherein N can be partially replaced by O, F, Cl, alone or in combination.
