Luminaire illumination and power distribution system

Abstract

A device and method for housing a terminator circuit and brightly distributing light from one surface and dimly distributing light from another surface with a single light source. Additionally, light may be distributed from a top surface, a bottom surface and through an edge surface. In operation, the light fixture of figure may provide tri-directional lighting by providing light from the LEDs directed from one side of the light fixture, while providing light from a second side of the light fixture in the opposite direction (but offset), and directing a third portion of light from one of the LED arrays through a light pipe to an edge of the fixture. This allows a lighting designer a wide range of aesthetics and lighting affects because light of different densities may be directed where needed.

What is claimed: 
     
         1 . A device including:
 a lens, said lens extruded from a first and a second plastic, each of said plastics having a first and second optical density respectively;   said lens further presenting a first and second surface substantially orthogonal to each other, wherein the first surface is substantially formed by the first plastic and the second surface is substantially formed by the second plastic;   a plurality of light sources, said light sources arranged in a linear array;   wherein a portion of light from said light sources is directed through the first surface and a portion of the light is directed through the second surface.   
     
     
         2 . The device of  claim 1  further including a light pipe operable to direct light from the light sources to either the first or the second surface. 
     
     
         3 . The device of  claim 1  wherein the first and second plastics are a different color. 
     
     
         4 . The device of  claim 1  wherein the first surface is substantially planar. 
     
     
         5 . The device of  claim 1  wherein the second surface forms and edge of the first surface. 
     
     
         6 . The device of  claim 1  wherein the lens is disposed over a track and the light sources are disposed in the track. 
     
     
         7 . A luminaire including:
 a single extruded lens having a plurality of plastics, each plastic having a different optical density;   a track, said track having a plurality of light sources disposed to splay light from the light sources to the lens,   wherein light passes through each of the plastics.   
     
     
         8 . The device of  claim 7  wherein the light sources are disposed on a circuit board, said circuit board including an inline sliding connector coupling the light sources to a power supply.
