Abstract
An LED lamp with heat dissipation mechanism having double heat pipe and tridimensional LEDs arrangement is disclosed. The lamp is composed of a heat-dissipation unit, a heat pipe whose one end is mounted on the heat-dissipation unit, a plurality of LED units mounted on an outer surface of the heat pipe, a fin module encompassing the heat-dissipation unit and a reflector mounted on a bottom of the heat-dissipation unit. The heat-dissipation unit has two basin-like casings. The LED units on the heat pipe are towards the reflector. Thus the reflector concentrates the light from the LED units.
