The controller receives vehicle position data, for example from a GPS system, and accesses a map database to identify a map location of the vehicle. The controller further analyzes the map to determine a most likely path of the vehicle based on the map location and other vehicle heading parameters. The controller then calculates the desired swivel angle of the first and second headlamps based on the most likely path of the vehicle, and the first and second swivel mechanisms manipulate the first and second headlamps to accordingly change the swivel angle of the headlamps.Type: GrantFiled: March 27, 2007Date of Patent: November 3, 2009Assignee: Visteon Global Technologies, Inc.Inventors: Faroog Abdel-kareem Ibrahim, Markus Klein, Christoph Schmidt

Publication number: 20090262546Abstract: The invention relates to a low beam headlight with at least one light module. The individual light module exhibits at least one light source and at least one primary lens connected downstream of the light source; and the light source is a luminescent diode. In addition, the low beam headlight has at least one secondary lens, which is connected optically downstream of the primary lens or the primary lenses. Both the primary and the secondary lens exhibit at least two lens segments, which are arranged one over the other. In addition, at least one lens segment of the primary lens and its assigned lens segment of the secondary lens lie outside the optical axis of the light module. The present invention develops a compact low beam headlight, whose light distribution has a clearly defined hot spot. The light intensity of the illumination decreases steadily in the direction of the basic distribution.Type: ApplicationFiled: February 14, 2007Publication date: October 22, 2009Applicant: SCHEFENACKER VISION SYSTEMS GERMANY GMBHInventors: Emil Stefanov, Veit Schwegler, Dagmar Wurtenberger

Patent number: 7600903Abstract: In the invention, a light device is proposed equipped with a DC motor for causing the tilting of a pivoting plate, in addition, in the invention, a solution is proposed for preventing the DC motor from degrading too quickly. To this end, it is therefore proposed to limit, for example by means of an electronic control card, the supply current to the motor to a limitation threshold, at least during the phases in which the DC motor is functioning in locked torque.Type: GrantFiled: May 14, 2004Date of Patent: October 13, 2009Assignee: Valeo VisionInventors: Alexander Mensales, David Hue

Publication number: 20090213606Abstract: A solid-state light source (10) comprising a plurality of LED units (12) arrayed to emit light generally about an axis (14). Each of the LED units (12) can comprise a number of LEDs, for example, up to five. They may all emit in a single color or multiple colors can be combined for a specific effect. A light transmissive light guide (16) is associated with the LED units (12) and has a plurality of input widows (18). Each LED unit (12) faces a respective input window (18) and each window (18) transversely intercepts the axis (14) and receives light from the LED units (12). The input windows (18) lead to a common output window (20) that is axially aligned with the input windows (18). The light guide (16) has smooth sidewalls (22) that extend between the input windows (18) and the output window (20).Type: ApplicationFiled: August 23, 2006Publication date: August 27, 2009Applicant: OSRAM SYLVANIA, INC.Inventors: Charles M.
