Abstract:
1. A surface light emitting apparatus, comprising: a light source bar including a light source configured to generate an optical signal; an optical distributor configured to divide the optical signal incident to the optical distributor into a plurality of optical signals; a light guide plate configured to confine the plurality of optical signals incident to the light guide plate in an inside thereof and transfer the plurality of optical signals; and a scattering pattern formed on a surface of the light guide plate and configured to emit a light by the optical signal transferred through the light guide plate; wherein the optical distributor is one of a Y-branch 3D optical waveguide, a comb-shaped optical waveguide, a sawtooth-shaped optical waveguide, and a waveguide including a plurality of micro triangular minors or a plurality of micro curved mirrors; wherein the optical distributor is a planar optical wave guide structure; and wherein the optical signal incident to the optical distributor and the plurality of optical signals incident to the light guide plate are on the same plane.
