20100103650 | Arrangement With a Semiconductor Chip and an Optical Waveguide Layer - An arrangement includes a semiconductor chip, which is designed to emit light during operation, and a cover layer, which lies across from the light-emitting surface of the semiconductor chip, such that light emitted from the semiconductor chip penetrates into the cover layer. In an area of the cover layer, overlapping with the chip, a light deflecting structure is provided by means of which light penetrating into the cover layer is deflected. The cover layer acts as an optical waveguide and is designed to emit the light such that it is distributed over the upper surface of cover layer. | 04-29-2010 |
20130293097 | LIGHTING DEVICE WITH LED CHIP AND PROTECTIVE CAST - 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. | 11-07-2013 |
