摘要： A lamp for a vehicle includes a light source unit for generating a first light; a light adjustment unit for adjusting a first light concentration for the first light to generate a second light having a second light concentration from the first light concentration; and a movable mirror unit for reflecting the second light to form an image of a predetermined shape on a road surface. A position where the image is formed on the road surface is changed depending on a position of the movable mirror unit.

摘要： There is provided a lighting device arranged to produce a controllable light beam for illuminating a scene. The device comprises an addressable spatial light modulator arranged to provide a selectable phase delay distribution to a beam of incident light. The device further comprises Fourier optics arranged to receive phase-modulated light from the spatial light modulator and form a light distribution. The device further comprises projection optics arranged to project the light distribution to form a pattern of illumination as said controllable light beam.

摘要： Bicycle light systems and methods operate to project multicolor lighting patterns on the front and/or rear of the torso of a bicycle rider. Multicolor light schemes provide increased visibility, accentuate the rider's form, and provide the rider with an enjoyable and thrilling riding experience. Low light intensity configurations effectively operate to light the rider's body while not shining excessive amounts of light other riders. Light housing configurations prevent unwanted light from reaching the rider's eyes, and limit the illumination patterns to desired locations on the rider's torso.

摘要： A lighting device for a motor vehicle, in particular a headlamp, comprising at least two, preferably three, light sources, from which light emanates during the operation of the lighting device, the light of each of the light sources differing from that of the other light sources with regard to its wavelength spectrum, comprising modulator, which bring about a modulation of the light emanating from the light sources during the operation of the lighting device, so that information is transmitted by the light, the lighting device having a mixer for mixing the light emanating from the individual light sources, so that white light emerges from the lighting device during the operation of the lighting device.

摘要： A lighting apparatus for vehicles with a housing sealed by a transparent covering panel, containing a light source unit and an optical unit for producing a predetermined light function, wherein the optical unit has a hologram element and/or diffractive element in which diffraction information for producing the light function is contained, wherein optics are disposed downstream of the hologram element and/or the diffractive element in the light beam path, so that light of different orders of diffraction emerging from the hologram element and/or the diffractive element produce different light functions.

摘要： A lighting device for a vehicle headlight, the lighting device having a first light module (105), a second light module (106) and a third light module (107), wherein, when the modules are installed in a vehicle, the first light module generates a first overall light distribution (A), the second light module generates a first partial light distribution (F), and the third light module generates a second partial light distribution (Z), these distributions being in a region in front of the vehicle. When the first and second light modules are illuminated at the same time, the first overall light distribution at least partially overlaps the first partial light distribution, forming a second overall light distribution (AF). The second partial light distribution lies underneath the hh line and at least partially overlaps the second overall light distribution (AF). When all three light modules are activated simultaneously, a third overall light distribution (AF′) is formed.

摘要： Provided is a vehicular headlamp including an excitation light source, a phosphor excited by the excitation light source, a projection lens, and a scanning mechanism configured to receive light generated by an excitation light source array on a reflective surface of a reflector and scan the light toward the phosphor. The excitation light source is formed as the excitation light source array having a plurality of light emitting portions. Between the excitation light source array and the scanning mechanism, a lens array having a plurality of light condensing portions is provided. The plurality of light condensing portions are arranged to respectively face the plurality of light emitting portions, and configured to condense lights emitted from respective light emitting portions on the reflective surface, respectively, and arrange respective optical images of reflected lights on the phosphor.
