Led lighting apparatus with uniform-emitting performance on wall-structure

An LED lighting apparatus with uniform-emitting performance on a wall structure, which allows light emitted in every direction when the light is emitted onto the wall structure to have given illuminance at which the light is most uniformly distributed onto the wall structure, the LED lighting apparatus comprising:

• a power part (10) for supplying a power source;
• a light source part (20) having an LED (21), a PCB (23) for mounting the LED (21) thereon, and a lens (25) located on bottom of the LED (21);
• an acrylic structure (30) spaced apart from the lens (25) by a given distance to pass the light emitted from the LED (21) therethrough;
• a fixing part (40) for fixing the power part (10), the light source part (20), and the acrylic structure (30);
• an aluminum body case (50) for covering the light source part (20);
• an aluminum fixing case (60) coupled to the aluminum body case (50) in such a manner as to be fastened to the wall structure;
• and
• a column (70) for supporting the aluminum fixing case (60) and the fixing part (40).
