    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.

    Abstract: An irradiation unit includes a pump radiation source for the emission of pump radiation; and a conversion element for the at least partial conversion of the pump radiation to a conversion radiation. During operation of the irradiation unit, the pump radiation is incident in the form of a beam from the pump radiation source on an incidence surface of the conversion element. A first portion of the pump radiation is incident on the conversion element in a central segment of the beam and a second portion of the pump radiation is incident on the conversion element in an edge segment of the beam surrounding the central segment. The conversion element is provided in such a way that a normalized degree of conversion and/or a normalized degree of scattering is lower for the second portion of the pump radiation than for the first portion of the pump radiation.

    Abstract: A light source arrangement is provided. The light source arrangement may include a plurality of semiconductor laser light sources, each having an optical axis. The semiconductor laser light sources are arranged in such a way that their optical axes are oriented parallel to one another so that respective laser light emission sides of the semiconductor laser light sources point in the same spatial direction. The light source arrangement may further include a deflection unit configured to collect and influence beam paths of the laser light emitted by the semiconductor laser light sources in order to form a beam bundle. The semiconductor laser light sources are arranged on a surface of a carrier, distributed at least two-dimensionally over the surface.
