PURPOSE: An LED lighting device for coupling a mold bar is provided to prevent damage to an LED due to collision by coupling an LED diffusion and protection cover with a coupling groove formed on the lower part of an aluminum frame. CONSTITUTION: A substrate includes a plurality of LEDs operated by a DC power source. The substrate is attached on an aluminum frame(24). The shape of the aluminum frame is matched with the back surface shape of the substrate. A one-touch elastic nut(25) is installed on the upper part of the aluminum frame. A power conversion circuit converts AC to DC power supply. |
