ABSTRACT:
A light conductor and restore spring assembly is made of molded light translucent material which exhibits a significant degree of deflectability and the further ability to rebound or restore to its original shape when released. The framework of the spring forms a light conductor. If the light path needs to be deviated from a straight path the framework of the spring may have reflective surfaces formed into the body of the assembly to reflect the light rays from the input end to the diffusing end of the light path. The external surfaces of the spring/light conductor assembly constrain the light loss by reflecting the light back into the assembly and redirecting it along its path and toward the reflective surfaces or the diffusing end of the light pipe.
