    摘要： A laser-based light source comprises a laser, an optical fiber, a conversion device, and a detector, the laser for emitting laser light with a laser peak emission wavelength, the optical fiber for guiding the laser light for being received at a first surface of the conversion device, the conversion device for converting at least a part of the laser light to converted light with a peak emission wavelength being longer than the laser peak emission wavelength, the optical fiber further for guiding a part of the converted light back in the direction of the laser and the detector for detecting at least a part of the back guided converted light. A vehicle headlight comprises such a laser-based light source, and a lighting system comprises such a vehicle headlight.

    摘要： Intrinsically safe laser sourced illumination. A system for illumination is disclosed, including a plurality of laser illumination sources configured to transmit laser beams; a dichroic mirror spaced from the plurality of laser illumination sources and having an aperture configured to allow the laser beams to pass through the dichroic mirror, the remaining surfaces of the dichroic mirror configured to reflect the laser beams; a phosphor element spaced from the dichroic mirror and coated with a substance to fluoresce when struck by the laser beams and configured to disperse the laser beams and to output combined light that includes fluorescent light and the dispersed laser beams; and an illumination output arranged to receive the combined light from the phosphor element and to output illuminating light containing both the fluorescent light and the dispersed laser beams. Methods are also disclosed.

    摘要： A headlamp (1) for vehicles having at least one laser light module (3l, 3m, 3r) which has a laser light source (11) and a phosphorus element (13) which is arranged downstream of the latter in the beam path and a front-end optical system (16) in which the at least one laser light module is arranged in a housing (2) of the headlamp which has a projection optical system (4) for projecting the light distribution generated in the focal plane of the projection optical system of the at least one laser light module into the carriageway space, and at least one deflection prism (20; 22, 23) is integrated into the at least one front-end optical system (16), which deflection prism (20; 22, 23) lies in the region of the laser beam (15; 15-1, 15-2) which occurs when the phosphorus element (13) is defective or missing and which deflects this laser beam occurring in the event of disruption and keeps it away from the projection optical system and therefore from the carriageway space.

    摘要： A lighting apparatus includes a first semiconductor light source configured to produce a first primary light beam, a second semiconductor light source configured to produce a second primary light beam, a phosphor volume configured to at least partly convert primary light into secondary light, a first deflection element configured to deflect the first primary light beam onto the phosphor volume, a second deflection element configured to deflect the second primary light beam onto the phosphor volume, a first light sensor which is sensitive to at least the primary light, and a second light sensor. The first deflection element is partly transmissive for the first primary light beam. The first light sensor can be irradiated by the component of the primary light beam which is transmitted by the first deflection element. The second light sensor can be irradiated by light which can be emitted by the phosphor volume.
