Patent attributes
A luminaire with a heat sink (1), which heat sink is formed by one integral piece of cold forged aluminum, comprising an essentially flat base portion (2), having a base surface with a center (2a) and an outer periphery (2b) and a set of heat dissipating fins (3, 4) extending from a first side of the base surface, in a direction normal to the base surface. The set includes at least one radial heat dissipating fin (3) having a cross section in a plane parallel to the base surface which cross section extends substantially in a radial direction from the center (2a) towards the outer periphery (2b), and at least one peripheral heat dissipating fin (4) having a cross section in a plane parallel to the base surface which cross section includes a portion extending in a direction parallel to the outer periphery (2b), wherein the peripheral heat dissipating fins (4) are arranged radially outside the radial heat dissipating fins (3).
