Patent number: 10813185Abstract: A lighting device is provided that has a light source arrangement with a plurality of semiconductor-based light sources in the form of light-emitting diodes. The light sources are bundled or collimated such that they each emit light in differently directed light cones with adjacent light cones overlapping. The lighting device has an adjusting device for adjustment of the direction of illumination and an actuating circuit connected to the adjusting device. The adjusting device adjusts intermediate stages for which the light-emitting diodes of adjacent and overlapping light cones operate and with varying light intensity in such a way the focal point of the light field produced by the light-emitting diodes lies between the focal points of adjacent light cones.Type: GrantFiled: April 9, 2019Date of Patent: October 20, 2020Assignee: SCHOTT AGInventors: Bernd Wölfing, Thomas Reichert, Achim Weil, Andreas Jurk, Björn Bleisinger

Patent number: 10261230Abstract: LED lighting devices are provided that include two optical waveguides and at least one LED in an intermediate region between end faces of the optical waveguides so that radiation from the LED is coupled into the optical waveguides through the end faces. A de-coupler is on outer circumferential surface regions of each of the two separate optical waveguides. The de-coupler reflects the radiation guided in the optical waveguides so that the radiation passes through the optical waveguides and is coupled out of the optical waveguides laterally. The intermediate region has a length that is selected so that a brightness difference, measured perpendicular to an axis of the optical waveguides in the center of the intermediate region, at a distance of 10 mm perpendicular to the axis of the optical waveguides is at most 25% based on a maximum value of brightness along the axis of the optical waveguides.Type: GrantFiled: September 15, 2016Date of Patent: April 16, 2019Assignee: Schott AGInventors: Ekkehard Gaydoul, Armin Plichta, Juergen Meinl, Bjoern Bleisinger, Martin Cramer, Thomas Reichert, Marc Timon Sprzagala, Sandra Mattheis

Patent number: 10231309Abstract: A light source is provided that includes at least two semiconductor light-emitting elements that emit light of different color, a light guide, an electronic control unit, and a light sensor. The light emitted by the elements is injected, at least partially, into the light guide and exits laterally from the light guide. The brightness of the elements can be adjusted by the electronic control unit. The light sensor is arranged to receive the light injected by the elements and laterally exiting from the light guide. The electronic control unit accumulates sensor signals from the light sensor over an integration time interval and compares the accumulated signals with a target value or range to determine a difference, changes a brightness of the elements in response to the difference, and changes the integration time interval in response to the difference or to a change in the target value.Type: GrantFiled: April 18, 2018Date of Patent: March 12, 2019Assignee: SCHOTT AGInventors: Bernd Wölfing, Thomas Reichert, Andreas Dietrich, Andreas Schneider, Björn Bleisinger, Marc Timon Sprzagala, Martin Cramer, Oliver Keiper, Sandra Mattheis

Patent number: 9516711Abstract: A light-emitting diode module is provided that includes a housing and a printed circuit board, which is connected to a light-emitting diode and which has an LED driver, a control module, and a circuit arrangement. The circuit arrangement has a DC/DC converter and a bypass connected in parallel to the DC/DC converter. The bypass is activatable by a comparator circuit. The comparator circuit is arranged between an input of the circuit arrangement and the DC/DC converter and detects the level of an input voltage of the circuit arrangement and compares it with a first and second threshold value. The comparator circuit activates the bypass when the input voltage is below the first threshold value and deactivates the bypass when the second threshold value is exceeded.Type: GrantFiled: November 15, 2010Date of Patent: December 6, 2016Assignee: SCHOTT AGInventors: Achim Weil, Bjoern Bleisinger, Stefan Siebenrock, Ulrich Schmitt
