A light fixture comprises two cooling elements and a plurality of semiconductor lighting elements, wherein each cooling element has a central portion and a wall portion which extends away from the central portion and at least partially surrounds an interior of a cooling element. The two cooling elements are arranged opposite one another. An annular opening for exchange of air with the environment is present between the two cooling elements. The semiconductor lighting elements are arranged on the outside of the wall portion of the cooling elements. A corresponding cooling element has two or more vanes, wherein all vanes are connected to one another by means of a central connecting element. Each vane extends in an axial direction and in a circumferential direction and has a curvature in the axial direction and preferably a curvature in the circumferential direction.
Light fixture comprising two cooling elements and a plurality of semiconductor lighting elements (13), wherein each cooling element has a central portion (3) and a wall portion (1) which extends away from the central portion (3) and at least partially surrounds an interior of a cooling element, characterised in that the two cooling elements are arranged opposite one another, in that the two cooling elements are arranged so that an annular opening (7) is present between them, and in that the semiconductor lighting elements (13) are arranged on the outside of the wall portions (1) of the cooling elements.
Cooling element for a light fixture having two or more vanes (1), wherein all vanes (1) are connected to one another by means of a central connecting element (3), wherein each vane (1) extends in an axial direction (A), characterised in that each vane (1) has a curvature in the axial direction (A).
