20130308332 | LASER-BASED WHITE LIGHT SOURCE - A device for generating white light is provided that includes at least one light source and at least one conversion medium. The light source emits light in the blue and/or ultraviolet spectral range. The light from the light source is generated by a laser and the light from the light source is focused by an optical system onto the conversion medium. The conversion medium converts at least part of the incident light into a different spectral range. | 11-21-2013 |
20140078772 | LED LIGHTING DEVICE - 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. | 03-20-2014 |
20150062953 | LIGHTING EQUIPMENT FOR GENERATING LIGHT OF HIGH LUMINANCE - Lighting equipment for generating white light from blue or violet excitation light and converted emitted yellow light is provided. The excitation light is directed at an oblique angle towards a converter that is attached to a carrier device, without the emitted illumination light impinging on the carrier device. | 03-05-2015 |
20150092392 | GENERATION OF WHITE LIGHT - An arrangement for generating white light is provided. The arrangement generates the white light by combining blue light and yellow light. The yellow light originates from a converter which transforms into yellow light virtually all blue light that enters the converter. | 04-02-2015 |

20080310182 | Device For Coupling Light Into a Fiber-Optic Optical Waveguide - A fiber-optic device includes at least one LED light source having at least one light-emitting semiconductor surface, a fiber-optic optical waveguide having a multiplicity of individual optical fibers combined at one end to form a light-receiving entrance surface, and a lens configuration having optical lenses associated directly with one another, for imaging the light from the LED light source onto the entrance surface. In order to optimize the coupling of LED light into an optical waveguide with regard to technical complexity, efficiency and economic costs, to make the light from different types of LED light sources usable in an identical manner and to avoid undesirable optical effects during the transmission of light, the lens configuration includes at least two aspherical lenses, with at least one input lens and one output lens having an increased diameter relative thereto, and an input lens is associated with each light-emitting semiconductor surface. | 12-18-2008 |
20150292699 | FIBER-OPTIC CONVERSION MODULE - A fiber-optic conversion module is provided as part of a lighting device on a vehicle. The module includes optical fibers with connectors, a light exit head, and a converter mounted on a cooling element. Shorter wavelength excitation light is fed to the optical fibers that emit the excitation light towards the converter arranged at an angle relative to the beam direction, at a light spot that remits useful light in a radiation angle in form of a cone of useful light and reflects excitation light as a Fresnel reflection substantially outside the cone of useful light, where Fresnel reflection is made harmless by a light stop. | 10-15-2015 |
