The invention relates to an LED lamp (L), having a light-emitting means with at least one LED, and a heat sink (K-K), characterized in that the heat sink (K-K) is configured such that a plurality of channels ('″) are formed through said heat sink for transporting away air which is heated by operation of the light-emitting means, wherein the channels (′″) are arranged in the form of a ring around an axis (A), and wherein the length of at least one channel (′″) is at least half the shortest diagonal or transversal in the transverse extent of the corresponding one channel. The arrangement according to the invention and in particular the configuration of the channels (′″) make it possible to achieve particularly effective dissipation of heat.
