摘要:
A light pipe is configured to provide a wide effective angle of illumination while simultaneously providing a substantially uniform distribution of light along a length of the light pipe. One or more reflective surfaces not aligned with an inner surface are disposed such that when at least one reflective surface is illuminated, light is emitted from the light pipe at one or more specified angles of light emission. A plurality of reflection points are formed on the inner surface to cause the specified angles when at least one of the reflective surfaces is illuminated. A light pipe is also provided having one or more exterior protrusions configured to function as a secondary light source. A second portion of an outer surface of the light pipe has a radius of curvature which differs from the radius of curvature of the first portion of the outer surface.
