  • Patent number: 9784428
    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.

  • Patent number: 9380652
    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.

  • Patent number: 9029907
    Abstract: An optoelectronic semiconductor component includes a radiation emitting semiconductor chip having a radiation coupling out area. Electromagnetic radiation generated in the semiconductor chip leaves the semiconductor chip via the radiation coupling out area. A converter element is disposed downstream of the semiconductor chip at its radiation coupling out area. The converter element is configured to convert electromagnetic radiation emitted by the semiconductor chip. The converter element has a first surface facing away from the radiation coupling out area. A reflective encapsulation encapsulates the semiconductor chip and portions of the converter element at side areas in a form-fitting manner. The first surface of the converter element is free of the reflective encapsulation.
