Abstract
Disclosed is a lighting apparatus using light-emitting diodes. The lighting apparatus includes: a housing in which an inner side surface is partitioned into a plurality of mounting surfaces and a plurality of cooling fins is prominently formed on an outer side surface; a plurality of light source blocks provided with a plurality of LED modules on an outer surface of a plurality of angle adjusting blocks having multi-step inclined surfaces, and mounted at positions selectively determined on the plurality of mounting surfaces of the housing so that light emitted from the LED modules can implement a predetermined light distribution type; and a protection cover for covering a lower portion of the housing.
