20080259630 | LENS ASSEMBLY - A lens assembly for use with a light source and including an inner lens and a light directing portion. The inner lens collects light rays from the light source through a light-collecting face and emits at least a portion of the light rays radially through a series of collimators. The light directing portion may be an outer lens having light-collecting faces and light-distributing faces. The light-collecting faces correspond with the collimators and distribute the light rays through light-distributing faces. The light direction portion may alternatively be an outer reflector. The reflector has a plurality of light-reflecting surfaces, corresponding to the collimators, and configured to reflect the light rays emitted from the collimators. | 10-23-2008 |
20080291683 | Near Field Lens - A lens for use with a light emitting source is provided. The lens has a main body with a light-collecting face and a light-emitting face and which defines an optical axis extending through the centers of these two faces. A pocket for receiving light from the light source is defined in the light-collecting face by an inner axially-facing surface surrounded by an inner radially-facing surface. The inner axially-facing surface is concave and has a spherical shape. The inner radially-facing surface has a non-spherical, tapered shape and extends between the axially-facing surface and an open end of the pocket. A light assembly incorporating the lens includes a light-emitting diode. | 11-27-2008 |
20080304277 | INCREASED EFFICIENCY LED PROJECTOR OPTIC ASSEMBLY - A projector optic assembly for generating and projecting a high gradient beam. The assembly includes a light pipe defining an optical axis and having a collection unit, a funneling unit, and an emitting surface. The collection unit extends from a first end to a transition plane defining the transition from the collection unit to the funneling unit. The collection unit is configured to collect light from a source and direct it through the transition plane, whereafter the funneling unit extends from the transition plane to the emitting surface. The emitting surface has an area smaller than an area of the transition plane selected to increase the efficiency of the funneling unit. Spaced apart from and generally opposite of the emitting surface is a condenser lens | 12-11-2008 |
20080310028 | NEAR FIELD LENS FOR A LIGHT ASSEMBLY - The present invention provides a near field lens for an automotive light assembly.

The radial collimating portion is structured to radially direct light in planes normal to the central axis and to collimate light in radial planes through the central axis. By extending the main body, a thin plate near field lens is provided. | 12-18-2008 |
20080310159 | NEAR FIELD LENS - A lens has a main body for use with at least one light source. The main body has a light-emitting face, a light-collecting face disposed opposite the light-emitting face, and a plurality of focal points, the latter of which form a focal ring. A central axis extends through the light-collecting face and the light-emitting face. The main body is substantially radially symmetrical about the central axis and the focal ring extends around the central axis of the main body of the lens. | 12-18-2008 |
20080310166 | Toroidal Lens - A lens, suitable for automotive applications, for use with a light source is provided. The lens has a main body defining a cross sectional shape with a curved side and a straight side. The main body is formed by rotating the cross sectional shape about an axis of revolution located outside the main body. The axis of revolution is parallel to the straight side of the cross section and passes through a focal point defined by the curved side. | 12-18-2008 |
