The present invention relates to a new block type surface light source control device, in which a photo sensor is mounted in the block type surface light source control device, so that a color is controlled, uniformity of lighting degree of an LED block is adjusted, and trouble of the LED block is detected. An LED lighting apparatus according to the present invention, an LED light source tool and a lighting tool are spaced apart at regular intervals through a light guide pipe. The LED light source tool includes an LED device for light output and an LED driving unit for driving the LED device. The lighting tool includes a light guide panel, a diffusion lens arranged at one side of the light guide panel for diffusing light introduced from the light guide pipe at the inside of the light guide panel in all directions, a reflective film arranged at one side surface of the inside of the light guide panel, and a diffusion film arranged at another inner side surface of the light guide panel for outputting the light to the outside. The light guide pipe is formed with an optical fiber to provide the light provided from the LED light source tool to the lighting tool. The lighting tool is formed by combining at least one lighting tool. The light guide pipe is formed with a plurality of optical fibers and provides the light provided from the LED light source tool to at least one of the lighting tool. The lighting tool is equipped with the photo sensor for detecting and transferring illumination light, and a trouble detecting sensor for detecting a trouble state. |
