Abstract: Various embodiments relate to a lighting device with an optoelectronic light source, an optical body downstream thereof for distributing the light, and a diffuser downstream of the latter, onto the light entry surface of which the light emitted by the optical body falls and the light exit surface of which represents a light emission surface of the lighting device. To homogenize the luminous intensity on the light exit surface, in addition to distributing the light with the optical body, the diffuser is not provided to be uniformly scattering to such an extent that light falling thereon in a central region is scattered more intensely than light falling thereon in an edge region.

Abstract: A phosphor LED for emitting light emitting diode light may include an LED designed for emitting blue primary light; and an LED phosphor designed and arranged such that it is excited by the primary light during operation and emits secondary light as a consequence, said secondary light forming at least a portion of the LED light. The LED phosphor may include a green phosphor and a red phosphor. The green phosphor and the red phosphor may be provided in a ratio such that the light emitting diode light in the CIE standard chromaticity system has a color locus in the green which is spaced apart from the Planckian locus, to be precise by at least 0.01 in terms of absolute value.
