The present invention relates to a lighting apparatus using a light-emitting diode, which improves overall performance of the lighting apparatus as well as design to produce various light distribution characteristics. The invention comprises: a housing having a reception groove of which the lower part is opened and the diameter increases toward the lower end thereof, wherein the inside of the reception groove is divided into a plurality of mounting surfaces, and a plurality of heat-dissipating pins are radially spaced in a protruding manner on the outer surface of the reception groove; plural light source blocks which are mounted along the mounting surface of the inner side of the housing, include plural light-emitting diode modules on the outer surface of an angle adjusting block having a multi-stepped slope, are set to have different illumination angles and brightness, and positioned selectively on the mounting surfaces to have the light emitted from the light-emitting diode module implement a predefined light distribution; and a protection cover covering the lower part of the housing. |
