Abstract:
A lighting device may include at least one partially light-transmissive cover which covers at least one light source, so that a hollow chamber is provided between the at least one light source and the cover, and at least one heat sink structure, which is at least one of at least partially arranged in the hollow chamber and is set at least partially into the cover.
Abstract:
An illumination device may include a first heat sink; a carrier substrate, which is populated on its front side by at least one light source, and is attached by its rear side to the first heat sink; and a second heat sink, which is arranged essentially in front of the carrier substrate; wherein the at least one light source is arranged outside of the second heat sink.
Abstract:
A lighting device (1; 21; 41) having at least one heat sink (5; 44) for cooling at least one light source, wherein the at least one heat sink (5; 44) comprises one or more at least bent sheet metal parts.
Abstract:
A cooling element for a lighting device having a plurality of cooling fins, wherein adjacent cooling fins delimit a cooling fin intermediate space with at least one air duct for connecting at least two cooling fin intermediate spaces.

Abstract:
A heat sink may be constructed from at least one sheet-metal part and may include at least one flow structure, wherein the flow structure is configured to guide cooling air along an inner side of the heat sink, and wherein the flow structure is configured to direct the cooling air at least partially along a longitudinal axis of the heat sink on the inner side of the heat sink.

Abstract:
A method for producing an LED lamp includes a lamp housing wherein at least one carrier circuit board equipped with LEDs is inserted into the lamp housing in such a way that at least a subregion of the lamp housing protrudes beyond the carrier circuit board with a projection, and the projection is at least partially deformed after insertion in such a way that the lamp housing is pressed with the carrier circuit board.
Abstract:
An illumination device comprising at least one reflector and at least one light generating unit, wherein the at least one reflector is designed and arranged to reflect at least a portion of a light emitted by the at least one light generating unit into a spatial region that cannot be directly irradiated thereby, and the at least one light generating unit comprises at least one illuminating region having a substantially uniform emission characteristic in a circumferential direction of the illumination device.
