Abstract: A radiation distribution system designed to produce a batwing distribution. The system may be used with radiative sources emitting in the visible spectrum or in other spectra. The system comprises a specially shaped lens disposed over a radiative source, such as an LED, for example. The lens and source are arranged between two reflector bodies, both of which have an elongated reflective surface that faces the source. The reflector bodies each have two different reflective surfaces that face outward and away from each other. The lens and both reflective surfaces work in concert to redirect a portion of the emitted radiation to create the desired batwing distribution. Several sources may be arranged linearly between a single pair of reflector bodies on a common surface to create a linear array of sources. Likewise, multiple linear arrays may be combined to form a two-dimensional array. In the two-dimensional configuration, linear arrays of sources are disposed on both sides of a reflector body, so that both of the reflective surfaces are utilized.

Abstract: An optical device for collecting light and selectively outputting or concentrating the light. A layer has an optical index of referaction n.sub.1, and top, bottom and side surfaces defining an angel of inclination .phi.. A back surface spans the top, bottom and side surface. A first layer is coupled to the bottom surface of the layer and has an index of refraction n.sub.2. The first layer index n.sub.2 causes light input through the back surface of the layer to be preferentially output into the first layer. A second layer is coupled to the bottom of the first layer and selectively causes output of light into ambient. Additional layers, such as alight polarization layer, a polarization converting layer and a post LCD diffuser layer can be used to make preferential use of polarized light of diffuse light having passed through the LCD layer to enhance viewing of the output light.

Abstract: An optical device for collecting light and selectively outputting or concentrating the light. A wedge layer has an optical index of refraction n.sub.1, and top, bottom and side surfaces intersecting to define an angle of inclination .phi.. A back surface spans the top, bottom and side surface. A first layer is coupled to the bottom surface of the layer and has an index of refraction n.sub.2. The first layer index n.sub.2 causes light input through the back surface of the layer to be preferentially output into the first layer. A second layer is coupled to the bottom of the first layer and selectively causes output of light into ambient. Additional layers, such as a light polarization layer, a polarization converting layer and a post LCD diffuser layer can be used to make preferential use of polarized light or diffuse light having passed through the LCD layer to enhance viewing of the output light.

Abstract: An LED light source using back-reflecting collection optics with a supporting structure and heat sink to block only a small amount of light. A reflector has a front and back side with an LED positioned on the front side of the reflector. A heat conducting body is positioned at least partially between the reflector and the LED. The heat conducting body provides a pathway for heat to flow from the LED toward the back side of the reflector.

A first layer is coupled to the bottom surface of the layer and has an index of refraction n.sub.2. The first layer index n.sub.2 causes light input through the back surface of the layer to be preferentially output into the first layer.
