Abstract
The present invention relates to an indirect lighting apparatus using an LED, comprising: a case unit provided along the perimeter of the upper part of a wall surface, and having a light emitting opening on a side opposite to the wall surface; a substrate mounted with an LED and provided at the innermost side of the inner bottom surface of the case unit; a light distributing unit for distributing light to the ceiling through the light emitting opening by reflecting the light emitted from the LED; and a cover unit for covering the light emitting opening of the case unit. The present invention uses a simple structure so that the apparatus is fixedly provided on the wall surface, and can be used as main lighting or mood lighting by providing the distributed light capable of selectively illuminating the entire ceiling.
