VEHICULAR LIGHT GUIDES AND ASSEMBLIES WITH UNIFORM ILLUMINATION

摘要

A light guide is provided that includes a light chamber defined by isotropically luminant top, bottom, and back surfaces, and a front surface having a translucent lens. The light guide also includes a reflective diaphragm within the chamber that defines a top gap between the diaphragm and the top surface, and a bottom gap between the diaphragm and the bottom surface. The light guide further includes an LED light source located between the diaphragm and the back surface of the chamber. The light guide may also be configured with a front surface having a partially transmissive lens and no reflective diaphragm. A vehicle lighting assembly is also provided that includes a plurality of interconnected light chamber sections comprising light guides.

1. A light guide, comprising:
a chamber comprising opposed ends, isotropic light-scattering upper and lower interior surfaces and a front lens; a reflective diaphragm within the chamber spaced from the lens and both of the surfaces; and an LED light source within the chamber, spaced behind the diaphragm at an end, wherein a ratio of gaps between the diaphragm and the surfaces to a distance between the surfaces is 1:4 to 1:9.
