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 mand a y-intercept nin a CIE standard chromaticity diagram, with the slope m=1.189 and the y-intercept n=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.
