Patent ID: 7936561

Claim:
A light-emitting diode (LED) heat dissipation aluminum bar and electricity conduction device comprising an LED circuit board, a heat dissipation aluminum bar, and fasteners, and characterized in that: the LED circuit board comprises a plurality of sections interconnected to each other, each section having a surface on which one or more than one LED socket is formed for receiving and retaining therein one or a plurality of LED's, the circuit board forming at least two electrically conductive holes for respectively receiving the fasteners therethrough for realizing electricity conduction of positive and negative electrodes so that fixing the circuit board in a receiving slot defined in the heat dissipation aluminum bar also realizes electricity conduction; the heat dissipation aluminum bar is formed of multiple sections interconnected to each other and an overall structure of the heat dissipation aluminum bar is composed of multiple heat dissipation fins and also comprises two structures of LED circuit board receiving slot and power channels, the LED circuit board receiving slot receiving the LED circuit board to fix therein, the power channels receiving and retaining electrically conductive bars that are enclosed by insulation therein, two power channels being provided to serve as positive and negative electrodes for the LED's; two openings are defined in a bottom of the receiving slot of the heat dissipation aluminum bar to communicate the power channels, the power channels each receiving therein an insulation that enclose the respective electrically conductive bar and forms a joint seam in a top thereof for the penetration of the respective fastener; and the fasteners serve as a major medium for electricity connection and are made of excellent metallic electrical conductor, the fasteners extending through the at least two electrically conductive holes defined in the LED circuit board and are further put through the insulations received in the power channels to engage the electrically conductive bars enclosed by the insulations.
