US 2013/0279202 A1 · Efficient Side-Light Distribution System

Abstract

Improved side-light distribution systems are disclosed. One exemplary system includes a light source and a side-light distribution member. The light source supplies light to the side-light distribution member having (1) an net port on the first end of the member for receiving the light and (2) a second end having a reflective means. The inlet port consists of part of the surface area of the first end of the member. The reflective means associated with the second end of the member receives light from the first end and directs light towards the first end. At least part of a surface area of the first end of outside of the inlet port includes a reflective means for receiving the light from the second end and directing the light towards the second end of the rod.

Dependent claims

An efficient side-light distribution system, comprising:

a) a side-light distribution member comprising an elongated rod having a first end for receiving light and a second end;
the elongated rod comprising an elongated sidewall and light-extraction means along at least part of the elongated sidewall for extracting light through the sidewall and distributing said light to one or more target areas;
b) a reflective means associated with the second end of the rod for receiving light from the first end of the rod and directing said light towards the first end of the rod;
c) a light source supplying light to the rod through an inlet port on the first end of the rod;
said port consisting of part of the surface area of the first end;
and
d) at least part of the surface area of the first end outside of the port having a reflective means for receiving light from the second end of the rod and directing the foregoing light towards the second end of the rod.
