Abstract
An LED lamp (100) includes a frame (12), at least one LED module (20), a heat sink (32) and a cover (50). The LED module has a plurality of LEDs (220). The heat sink is mounted on the frame. The at least one LED module is attached to a bottom of the heat sink, whereby heat generated by the LEDs can be dissipated by the heat sink. A heat pipe (35) interconnects the heat sink and the cover. Thus, the heat generated by the LEDs can also be dissipated by the cover via the heat pipe. The cover is secured so as to shield a top portion of the heat sink and space from the top portion of the heat sink.
