A light source may include an LED chip having a light-emitting surface, on which a luminophore layer is arranged. The luminophore layer may include adjacently arranged regions having different luminophores. A lighting device may include at least one light source.
Abstract:
The lighting device has at least one LED chip that is potted by means of a potting compound, which potting compound has a light-transmissive, castable and curable matrix material comprising scattering volumes as filler material, wherein the scattering volumes are distributed inhomogeneously over a thickness of the potting compound and these scattering volumes have a lower density than the matrix material in its castable state. A method is used for producing a lighting device, which comprises at least one LED chip, by means of at least the following steps: potting the at least one LED chip by means of a potting compound containing scattering volumes, wherein the scattering volumes have a lower density than a matrix material of the potting compound in this state; curing the potting compound so that an inhomogeneous distribution of the scattering volumes is obtained owing to floating of the scattering volumes in the matrix material.

Various embodiments may relate to A light-emitting diode, including an LED chip having at least one emitter surface for emitting primary light, and a plurality of luminescent regions, which are connected optically downstream from the at least one emitter surface. At least one harder one of the luminescent regions is embedded in another, softer one of the luminescent regions.
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 light-emitting diode module for emitting white light includes a first light emitting diode chip for generating radiation in the blue spectral range having a first peak wavelength, a second light emitting diode chip for generating radiation in the blue spectral range having a second peak wavelength, a third light emitting diode chip for generating radiation in the red spectral range having a third peak wavelength, a first and a second phosphors disposed downstream of the first and the second light emitting diode chips, respectively. The first light emitting diode chip with the first phosphor generates a first mixed radiation and the second light emitting diode chip with the second phosphor generates a second mixed radiation. The first phosphor exhibits a first absorption maximum at a wavelength greater than the first peak wavelength. The second phosphor exhibits a second absorption maximum at a wavelength less than the second peak wavelength.
