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 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:
In various embodiments, an electronics housing for a lamp is provided, wherein an electronics printed circuit board is accommodated in an accommodating area surrounded by the electronics housing, and the electronics housing has an elongate channel, the channel connecting an outer side of the electronics housing to the accommodating area and extending substantially parallel to and offset with respect to the electronics printed circuit board.
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.
