ABSTRACT:
An LED lamp adapted for lighting includes a heat sink (30), a bowl-shaped cover (20) attached to a bottom portion of the heat sink, a lamp seat (10) secured below the cover, a plurality of LEDs (54) mounted on an outside surface of the heat sink, and a plurality of heat pipes (40) contacting with interior face of the heat sink. The heat sink has a plurality of fins (34, 36) extending from sidewalls thereof. The cover has a plurality of apertures (220) defined on lateral wall thereof. The heat generated by the LEDs can be transferred to the heat sink evenly via the heat pipes, and is then dispersed to ambient air efficiently and rapidly.
