Abstract

Disclosed is a light apparatus using light emitting diodes that includes: a base body member having a mounting surface on its one surface; a plurality of inclined block members each of which is mounted on the mounting surface of the base body member and has an inclined surface on one surface thereof; and light emitting diode module members that are mounted on the inclined surfaces of the inclined block members. According to the disclosure, it is possible to easily form various light distributions required for the lighting design by combining the inclined block members and the light emitting diode module members that are mounted on the mounting surfaces of the base body member, and various light distributions can be formed, which makes it possible to improve flexibility in the lighting design and to improve lighting efficiency for an object to be illuminated.
