PURPOSE: An LED(Light Emitting Diode) plane light source apparatus is provided to emit the heat generated from an LED lighting apparatus efficiently by arranging at least more than one ventilating hole on a heat dissipation plate. CONSTITUTION: An LED lighting device comprises an light diffusing device(110), a frame(120) for fixing the light diffusing device, an LED(130), an LED circuit board(140) for driving the LED, a heat dissipation plate(150), an LED power supply substrate(161), and an end cap(160). The LED lighting device is used for the illumination. The LED lighting device is configured to be simply assembled. The flow of the air cools the heat generated through the heat dissipation plate. |
