ABSTRACT:
A lighting device of the invention includes: a plurality of light sources; and an optical waveguide, wherein light emitted from the plurality of light sources is incident from a side of the optical waveguide and then emitted from one main plane of the optical waveguide. The optical waveguide includes a first inclined plane for reflecting light emitted from a first light source and then emitting the light from the one main plane, and a second inclined plane for reflecting light emitted from a second light source and then emitting the light from the one main plane at an exit angle different from the light emitted from the first light source, and wherein each of the light sources is independently driven.
