  • Patent number: 11421846
    Abstract: High beam headlight that can be produced with a small installation length with high efficiency and also provide effective low-cost manufacturability are described. For this purpose, a light source array having a plurality of light sources is combined with a honeycomb condenser. A collimator connected between the honeycomb condenser and the light source array illuminates the honeycomb condenser with collimated light of the plurality of light sources of the light source array. The arrangement of the components is such that the collimated light from a first light source leads to crosstalk-free irradiation of the honeycomb condenser and illumination of a first far-field segment. For each of the at least one second light source of the light source array, the collimated light of the respective second light source leads to irradiation of the honeycomb condenser with channel crosstalk and an illumination of a second far-field segment oriented obliquely with the first far-field segment.

  • Patent number: 11327325
    Abstract: Optical beam former for generating an emerging light beam from an incident light beam, the optical beam former including: a condenser lens array including several condenser lenses; and a projection lens array arranged in parallel to the condenser lens array and including several projection lenses; wherein exactly one of the projection lenses is assigned to each of the condenser lenses so that several optical channels are formed and so that each of the several optical channels generates a partial light beam of the emerging light beam, said partial light beam emerging in an angle-of-emergence range with a partial intensity distribution that is homogenous with respect to an angle of emergence, from an incident partial light beam, wherein the admissible angle-of-incidence ranges of the optical channels have the same size as to the magnitude in a plane extending in parallel to the optical axes of the condenser lenses; and wherein the angle-of-emergence ranges of at least two of the optical channels are different s

  • Publication number: 20220128827
    Abstract: An optical device for imaging a first, object-side set of mutually parallel bundles of beams onto an image surface, includes an optical beam expansion unit; an optical rearrangement unit configured to rearrange the first set of mutually parallel bundles of beams while maintaining mutually parallelism to obtain a second set of mutually parallel bundles of beams; an optical element configured to direct the second set of one or more bundles of beams onto the optical beam expansion unit by means of bundling, so that the optical beam expansion unit is reached by a third set of bundles of beams, the optical beam expansion unit being configured to expand each bundle of beams of the third set to obtain a fourth set of expanded bundles of beams; and an optical imaging unit configured to image the fourth set of expanded bundles of beams onto the image surface.

  • Patent number: 8469549
    Abstract: A beam shaper according to an embodiment of the present invention for a light source arrangement for generating a radiation profile includes a multitude of adjacently arranged optical beam-shaping elements, each belonging to one type of a plurality of different types with different optical characteristics. When illuminated together, the beam-shaping elements effect the radiation profile of the beam shaper and each include an intensity-modulating element and a refractive element.

  • Patent number: 7475333
    Abstract: Systems and methods for defining a form with a plurality of layout items for data presentation by a business application provide a tree view with tree nodes to represent the layout items, wherein the view visualizes structure information, a processing order, a selected tree node to represent a selected layout item; provide a property view to display properties of the selected layout item; provide a layout view to display items, wherein the selected layout item is highlighted; modify the selected layout item and the processing order through interaction with a user; and create a form definition document. The compatibility of layout items and processing order with a predefined data interface of the business application is verified as well.
