    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: 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.
