Publication number: 20060104076Abstract: The aim of the invention is to achieve an optimal illumination provided by a light guide having a structurally simple design. To this end, the reflecting surfaces (13, 14) are offset to one another while extending transversal to the beam direction of the lighting means (8, 11) and, when viewed in the beam direction, they join one another without forming, in essence, any gaps. As a result, no shadows are formed between the individual reflecting surfaces (13, 14) thereby enabling an optimal utilization of light emitted by the lighting means (8, 11). The inventive light guide is provided for lighting motor vehicles.Type: ApplicationFiled: October 25, 2003Publication date: May 18, 2006Applicant: Schefenacker Vision Systems Germany GmbHInventor: Andreas Erber

Publication number: 20060067084Abstract: Light guide for lights, in particular for motor vehicle lights. The light guide has a light source whose radiated light is directed out of the light guide at a light emission side by a reflective structure over at least a part of the length of the light guide. In order to design a light guide such that a desired luminance distribution can be achieved in a simple manner therewith, the proportion of reflective surface in a region of the reflective structure located closer to the light source is a smaller or larger part of the total reflective surface of the light guide than the proportion of reflective surface in a region of the reflective structure located further away from the light source. A desirable luminance distribution can be obtained easily in this way. The light guide is especially suitable for motor vehicle lights.Type: ApplicationFiled: September 21, 2005Publication date: March 30, 2006Applicant: Schefenacker Vision Systems Germany GmbHInventor: Emil Stefanov

Publication number: 20060050424Abstract: Exterior rearview mirror for vehicles, in particular for motor vehicles. The exterior rearview mirror has a mirror body that is rotatably attached to a mirror base and whose operating position is determined by contact between at least one stop and at least one opposing stop. In order to design the exterior rearview mirror to ensure that the generation of noise in the mirror during driving or as a result of shocks is no longer bothersome, at least one noise damping device is associated with at least the area of contact between stop and opposing stop. As a result, the sound waves caused by the constant striking together of the stop and opposing stop are largely absorbed by the noise damping device so that the sound does not reach the outside, or does so to only a small degree. The exterior rearview mirror is suitable for use in motor vehicles.Type: ApplicationFiled: August 25, 2005Publication date: March 9, 2006Applicant: Schefenacker Vision Systems Germany GmbHInventors: Jürgen Tilg, Jörg Kuhn

Publication number: 20060050423Abstract: Exterior rearview mirror for vehicles, preferably for motor vehicles. The exterior rearview mirror has a mirror base, and a mirror body, which can be folded relative to the mirror base and which has a housing. The housing of the mirror body is approximately rectangular when viewed from the side. It is connected to the laterally projecting part of the mirror base in the corner region of the housing. In order to design the exterior rearview mirror such that it is problem-free in use, the housing transitions through a narrow section into a connecting part to the mirror base. The mirror body is mounted on the mirror base by means of this connecting part. Consequently, the overall height of the mirror base can be kept very small. The narrow section of the mirror body prevents wind noises from occurring, since the slip stream can easily flow past the narrow section without catching on parts of the exterior rearview mirror.Type: ApplicationFiled: September 1, 2005Publication date: March 9, 2006Applicant: Schefenacker Vision Systems Germany GmbHInventors: Florin Secanu, Bernd Waldmann, Karl-Heinz Leonberger, Alexander Pirner

Publication number: 20050219857Abstract: The light of luminous units known in prior art is laterally radiated, wherefore LEDs (10 to 13) have to be arranged in an inclined manner on separate sheet metal supports, conductor films, or printed circuit boards. Using such supports and fastening the LEDs (10 to 13) is technically complex and costly. In order to be able to arrange the laterally radiating luminous means (10 to 13) in a simple, low-cost manner without using any additional supports, said luminous means (10 to 13) is provided with a fully reflecting surface (14), on which the beams (S) are reflected towards a reflector (3) that reflects the beams (S) in the direction of a light disk (2). The fully reflecting surface (14) can be arranged according to specific requirements in such a way that the light falls in the desired direction. No additional supports are required. The inventive luminous unit is preferably used in sideview mirrors of motor vehicles but can also be used in all areas of signal technology and illumination engineering.Type: ApplicationFiled: February 14, 2003Publication date: October 6, 2005Applicant: Schefenacker Vision Systems Germany GmbH & Co.

Publication number: 20050218837Abstract: Method of triggering at least one illuminating means, and triggering circuit for carrying out such method. On motor vehicles, the illuminating means are increasingly being formed by LEDs. Owing to the great possible operating voltages of the on-board network, such illuminants cause great power losses at high voltages. Besides, the networks aboard motor vehicles are often unstable. So that reliable operation will be possible with simple design layout, the illuminating means is operated in pulse mode when a certain current/voltage level is exceeded. The triggering circuit has a microcontroller, which is supplied with a part of the current/voltage signal supplied to the illuminating means. The microcontroller has an output to which the illuminating means is connected with interposition of a switch. In pulse mode, the ascent of the power loss is substantially reduced. Brightness fluctuations are regulated out. The triggering and the triggering circuit are advantageously employed for motor vehicle lamps.Type: ApplicationFiled: January 26, 2005Publication date: October 6, 2005Applicant: Schefenacker Vision Systems Germany GmbHInventor: Volker Zipf
