Abstract

Provided is a heat sink for an LED lamp where separate heat-dissipating fins can be coupled to a body of the heat sink to widen heat transfer area while being firmly supported, with the heat sink maintaining a light weight. The heat sink for an LED lamp includes: a heat sink body; and a plurality of heat-dissipating fins arranged on an outer peripheral surface of the heat sink body so that inner edges thereof contact the outer peripheral surface of the heat sink. Thus, since the heat sink body and the heat-dissipating fins are separately produced and coupled to each other, the entire weight of the heat sink can become light and the heat dissipation efficiency thereof can enhanced.
