OPTICAL LIGHT PIPE WITH UNIFORM LIT INTENSITY

摘要

The disclosure of the present application includes a light pipe assembly having a light pipe with a proximal end, an opposing distal end, a length between the proximal end and the distal end, and a surface, the surface having an emitting portion and an overlay portion, where the light pipe is a material capable of transmitting light with a first refractive index; and a reflective secondary surface having a second refractive index and a width, the reflective secondary surface positioned adjacent the overlay portion of the light pipe, where the first refractive index is greater than the refractive index of air, and the second refractive index is greater than the first refractive index. In at least one embodiment, the reflective secondary surface is a non-metallic material capable of reflecting light. In at least one embodiment, the width of the reflective secondary surface varies along the length of the light pipe.

主权项

1. A light pipe assembly, the light pipe assembly comprising:
a light pipe having a proximal end, an opposing distal end, a length between the proximal end and the distal end, and a surface, the surface comprising an emitting portion and an overlay portion, wherein the light pipe is comprised of a material capable of transmitting light with a first refractive index; and a reflective secondary surface comprising a second refractive index and a width, the reflective secondary surface disposed adjacent the overlay portion of the light pipe, wherein the first refractive index is greater than the refractive index of air, and the second refractive index is greater than the first refractive index.
