Abstract
A method of illuminating an object by capturing light from a light source with a TIR lens, redirecting the captured light from the light source in a single direction using the TIR lens, and channeling the redirected light through a light pipe to a plane at or before the object to maximize brightness of the light from the light source at the plane.
