Abstract

A light-emitting diode (LED) heat dissipation aluminum bar and electricity conduction device includes a heat dissipation aluminum bar having a structure formed of multiple sections each having multiple heat dissipation fins. The heat dissipation aluminum bar forms a LED circuit board receiving slot and power channels and each power channel receives therein an insulation that encloses an electrically conductive bars. When an LED circuit board is received and secured in the LED circuit board receiving slot by fasteners, the fasteners, which are made electrically conductive, penetrate the insulations to contact the electrically conductive bars so as to supply electricity to the LED circuit board at the same time of fixing the LED circuit board. The LED circuit board has a structure formed of multiple sections interconnected to each other to allow for adjustment of the overall length thereof.
