Abstract

The present invention relates to a fluorescent light type LED lighting apparatus wherein an inclined gripping surface formed on a heat radiation frame is used to tighten a screw in one direction only so that the PCB width is reduced and also the number of parts and assembly workers and time required are reduced so as to markedly improve productivity. To achieve the above, the present invention comprises: a light source part wherein an LED (light-emitting diode) is arranged and built in; a heat radiation frame formed with an open rear, wherein at least one line of the loading table for the light source part, a transmission cover combination part formed on both sides of said light source part loading table, and radiation fins that are formed on the other face of said light source part loading table, are furnished lengthwise, and said light source part loading table is configured such that a PCB seat part that corresponds to the width dimension of said PCB, an inclined gripping surface that is formed on one side of said PCB seat part and intended to grip the top of one side of the PCB with the inclined surface and a screw combination channel that is formed on another side of said PCB seat part, are furnished lengthwise; a plurality of screws that are combined in said screw combination channel at a set interval to pressurize and fix the top corner to the other side of the PCB; a transmission cover that covers said light source part and has both end parts combined with the transmission cover combination part of the heat radiation frame; and a side cover that finishes and fastens both ends of said heat radiation frame and transmission cover and has an electrical connection terminal furnished externally.
