20080225548 | ILLUMINATING DEVICE - An illuminating device has a light pipe that is elongate in shape and has a light-emitting face running in the direction of a longitudinal axis. A light-reflecting face is disposed opposite the light-emitting face, and the light-reflecting face has a plurality of prismatic cuts. Each prismatic cut includes a front face oriented at an angle B from a normal axis, the normal axis being 90 degrees from the longitudinal axis of the light pipe. The angle B is in the range of about 5 degrees to about 45 degrees and is such that it allows light to refract through at least one prismatic cut and then be internally reflected. | 09-18-2008 |
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 |
20080310028 | NEAR FIELD LENS FOR A LIGHT ASSEMBLY - The present invention provides a near field lens for an automotive light assembly. The lens comprises a main body having a radial collimating portion formed as a rotation about a central axis. A light-collecting faces defines pocket in the main body and receives light from the light source. 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 |
20090274419 | MANIFOLD-TYPE LIGHTGUIDE WITH REDUCED THICKNESS - A light guide includes a body having an elongate shape and a plurality of light-reflecting faces and light-emitting faces extending along the body. The light-reflecting faces extend in a stepped fashion along the body in the direction of a longitudinal axis of the light guide and are configured to reflect light rays by the principle of total internal reflection. Each light-emitting face is disposed along the body opposite a corresponding light-reflecting face. Each light-emitting face is configured to emit light reflected by the corresponding light-reflecting face. The light-emitting faces are also disposed on the body in a stepped fashion. Steps of the light-emitting faces correspond to steps of the light-reflecting faces. In another aspect, the light-reflecting faces are separated by stepped-down faces. The stepped-down faces are oriented at a stepped-down angle in the range of about 1 and 10 degrees with respect to the longitudinal axis of the light guide. | 11-05-2009 |
20120218773 | SEMICONDUCTOR LUMINAIRE - A semiconductor luminaire includes a carrier; an optoelectronic semiconductor chip mounted on the carrier, the semiconductor chip emitting ultraviolet or visible radiation; a luminaire housing not covering the semiconductor chip in a direction of main emittance; an optical cover placed downstream of the semiconductor chip in a direction of mails emittance: and an index matching layer located between the semiconductor chip mid the optical cover, wherein the optical cover provides a radiation exit surface of the luminaire, and wherein radiation running along the direction of main emittance from the semiconductor chip to the radiation exit surface solely propagates in solid or liquid materials. | 08-30-2012 |
20130081610 | Oven Lighting - An oven lighting which comprises an LED module with at least one LED and an optical fiber bundle. The optical fiber bundle has at least one light input end adjacent to the LED module and at least one light output end adjacent to a cavity wall of an oven cavity for illuminating the oven cavity. | 04-04-2013 |
