1. A light-emitting diode (LED) lamp, comprising:
- a polygonal heat-dissipation unit comprising;
a polygonal hollow column having two ends provided with a first opening and a second opening, respectively, the polygonal hollow column further having an outer surface and an inner surface; and
a plurality of fins thermally disposed on the inner surface of the polygonal hollow column; and
a plurality of lighting modules disposed on the outer surface of the polygonal hollow column successively and each comprising;
a light-emitting unit comprising a circuit board and a plurality of LEDs, the circuit board being thermally disposed on the outer surface of the polygonal hollow column, and the LEDs being electrically connected to and provided on the circuit board;
a first reflecting element having a first reflecting surface placed in light paths of the LEDs of the light-emitting unit; and
a second reflecting element having a second reflecting surface placed in a light path of light reflected off the first reflecting element.

Abstract
A light-emitting diode (LED) lamp and a polygonal heat-dissipation structure thereof are provided. The LED lamp includes a polygonal heat-dissipation unit and a lighting module. The polygonal heat-dissipation unit has a polygonal hollow column and fins. The fins and the lighting module are thermally disposed on an inner surface and an outer surface of the polygonal hollow column, respectively. Thus, heat generated by the lighting module is dissipated by the fins rapidly. As the fins are thermally disposed on the inner surface of the polygon hollow column instead of being exposed, the volume of the LED lamp can be minimized, and the look of the LED lamp also can be prettified.
