Abstract (en)
[origin: WO2012007403A1] The heat sink (4) is provided in particular for a semiconductor lamp (1), wherein the heat sink is constructed from at least one sheet-metal part and has at least one flow structure (3a) wherein the flow structure is designed to guide cooling air (A) along an inner side (9b) of the heat sink (4) and wherein the flow structure is designed to direct the cooling air at the inner side of the heat sink at least partly along a longitudinal axis (L) of the heat sink. The semiconductor lamp (1), more particularly retrofit lamp, has at least one heat sink (4) of this type.
