PURPOSE: A LED surface lighting device is provided to enable the super-slimming and the maximization of the light efficiency by optimizing the installation structure of a power control unit. CONSTITUTION: A frame(20) forms structure of an angular type and a rectangular outline structure, and is formed in a structure in which a LED array(30) is able to be installed. Each of a curved part is formed in the part where each edge of the frame meets. An accommodation space(24a) is formed in each curved part. In the accommodation space a power control unit(90) is built in. The LED array is installed along the inner wall of the frame and the power control unit is electrically connected in an end of the LED array. |
