| 20110095311 | Configuration of Multiple LED Module - A configuration of multiple LED modules having a plurality of LED modules that each contain a carrier that has a first main area, a second main area and at least one semiconductor layer. The first main area has a planar configuration. The LED modules also include a plurality of LED semiconductor bodies that applied on the first main area of the carrier. In addition, the multiple LED modules include a common heat sink, where the carrier of the LED modules in each case are connected to the common heat sink on the second main area. | 04-28-2011 |
| 20100200864 | Method for Fabricating a Semiconductor Component Based on GaN - A semiconductor component has a plurality of GaN-based layers, which are preferably used to generate radiation, produced in a fabrication process. In the process, the plurality of GaN-based layers are applied to a composite substrate that includes a substrate body and an interlayer. A coefficient of thermal expansion of the substrate body is similar to or preferably greater than the coefficient of thermal expansion of the GaN-based layers, and the GaN-based layers are deposited on the interlayer. The interlayer and the substrate body are preferably joined by a wafer bonding process. | 08-12-2010 |
| 20090302770 | Circuit for compensating thermal variations, lamp, lighting module and method for operating the same - A circuit for adjusting and for at least partially compensating, respectively, thermal variations is provided, where a current source is connected to a temperature compensation unit, where the temperature compensation unit at least partially compensates thermal variations of the current source, wherein the temperature compensation unit has at least one device having a temperature coefficient, in particular having a negative temperature coefficient. Further a lighting module or a lamp may have such a circuit as well as a method for operating the circuit and/or the lamp and the lighting modules, respectively. | 12-10-2009 |
| 20090296382 | Protective sheath for a LED band - The protective sheath has a basis for attaching the LED band and an at least partially light-transmissive covering attachable thereto, wherein the basis and the covering form an accommodation space for the LED band in the attached state. | 12-03-2009 |
