System and method for extending viewing angle of light emitted from light pipe |
摘要 |
Described is a system with a light pipe body having a first end and a second end, wherein a light source provides light beams at a first end of the light pipe body, the light beams traveling through the light pipe body. The system further includes a light-emitting surface coupled to the second end of the light pipe body, wherein the light beams travel from the light pipe body to the light-emitting surface. The system also has dispersion structures disposed on a surface of the light-emitting surface, wherein the dispersion structures are protrusions from the surface of the light-emitting surface, the light beams traveling from the light-emitting surface to the dispersion structures and being emitted from the dispersion structures at a plurality of angles.
