Abstract
This specification discloses heatsinks comprising a continuous sheet of thermally conductive material folded into a structure comprising a plurality of fins defined by bends in the sheet and arranged to transfer heat to surrounding air. The sheet may be further folded to form a planar surface defined by one or more bends in the sheet and on which one or more LEDs may be mounted. Optionally, the sheet may be further folded to partially enclose the fins within a tunnel formed by side walls defined by bends in the sheet.
