The present invention relates to a flat fireproof LED lighting device in which fire retardant including a heat emitting metal sheet is coated on a flat LED lighting device so that a light guide plate is prevented from melting in case of fire in order to suppress the spread of fire and drastically improve heat emission and quality. The present invention for realizing this comprises a light emitting unit in which LEDs are consecutively installed on a PCB, a light guide plate for inducing and diffusing light, and a heat emitting unit for emitting the heat of the light emitting unit which are all combined in the flat LED lighting device. An incombustible coating that covers fire retardant on the external surface of the flat LED lighting device is additionally included to enhance fireproof features of the light guide plate wherein the incombustible coating covers a light emitting surface of the light guide plate and is incombustible. The present invention further comprises a floodlight PC (Poly Carbonate) plate made of a floodlight body, a heat emitting metal sheet having a heat emitting function by contacting the heat emitting unit for heat exchange and covering the back of the light guide plate and a metal tape surrounding the side circumference of a laminate in which the floodlight PC plate, the light guide plate and the heat emitting metal sheet are sequentially laminated.
