20080285301 | LIGHTING DEVICE COMPRISING A PLURALITY OF SEMICONDUCTOR LIGHT SOURCES - A lighting device is disclosed comprising a plurality of semiconductor light sources disposed on a carrier, wherein the light from the light sources is coupled into assigned lightguides at a set angle to the surface normals of the carrier and the lightguides are provided with reflecting and light exit faces such that the envelope of the light outcoupling faces forms a curved surface segment. | 11-20-2008 |
20080315227 | Light-Emitting Diode Arrangement - A light-emitting diode arrangement is disclosed, comprising at least one light-emitting diode (LED) chip with a radiation decoupling surface through which a large portion of the electromagnetic radiation generated in the LED chip exits in a main direction of emission; a housing laterally surrounding the LED chip; and a reflective optic disposed after the radiation decoupling surface in the main direction of emission. The LED arrangement is particularly well suited for use in devices such as camera-equipped cell phones, digital cameras or video cameras. | 12-25-2008 |
20090129080 | Lighting means having a primary optics element and an optical apparatus - A lighting device with a light source followed by an optical apparatus in an emission direction, and a primary optics element with a light inlet and a light outlet being arranged between the light source and the optical apparatus. The primary optics element is designed such that desired characteristics of the light beam are formed within the primary optics element by deliberate reflections on specially shaped reflective surfaces of the primary optics element. | 05-21-2009 |
20090251918 | LIGHTING DEVICE, AUTOMOTIVE HEADLIGHTS AND METHOD FOR PRODUCING A LIGHTING DEVICE - Disclosed is a lighting device comprising at least one LED and at least one optical element, wherein the LED and the optical element are aligned with each other by means of at least one dowel pin. A method of making such a lighting device is also specified. The described lighting device is particularly well suited for use in a vehicle headlight. | 10-08-2009 |
20130154137 | OPTICAL ELEMENT AND METHOD FOR THE PRODUCTION THEREOF - Described is an optical element for guiding electromagnetic radiation. The optical element includes a base body and at least one film, wherein the film is configured to adhere to the base body to form an intimate connection with the base body without using an adhesion promoting interlayer and is arranged such that the electromagnetic radiation passes through it. | 06-20-2013 |
