Abstract: A semiconductor illuminating device is disclosed. The device includes an LED configured for emitting blue primary radiation and an LED phosphor arranged and configured such that it emits secondary light that forms at least one component of the illumination light, wherein the LED phosphor comprises a red phosphor for emitting red light as a component of the secondary light and a green phosphor for emitting green light as a component of the secondary light, wherein the green light has a color point located above a first straight line having a slope m1 and a y-intercept n1 in a CIE standard chromaticity diagram, with the slope m1=1.189 and the y-intercept n1=0.226, and wherein the components of the illumination light are at such a ratio to one another that the illumination light has a color temperature of at most 5500 K.

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.
