Abstract: The present disclosure provides an apparatus for generating fiber delivered laser-induced white light. The apparatus includes a package case enclosing a board member with an electrical connector through a cover member and a laser module configured to the board member inside the package case. The laser module comprises a support member, at least one laser diode device configured to emit a laser light of a first wavelength, a set of optics to guide the laser light towards an output port. Additionally, the apparatus includes a fiber assembly configured to receive the laser light from the output port for further delivering to a light head member disposed in a remote destination. A phosphor material disposed in the light head member receives the laser light exited from the fiber assembly to induce a phosphor emission of a second wavelength for producing a white light emission substantially reflected therefrom for various applications.

Abstract: Reliability of an in-vehicle headlight is improved by changing a light distribution pattern without using any mechanical configuration. The in-vehicle headlight includes a laser light source 1, a spatial light modulator 3, a spatial-light-modulator controller, and a projection lens 5. The laser light source 1 emits a laser light beam 10. The spatial light modulator 3 modulates a phase distribution of the laser light beam 10 emitted by the laser light source 1. The spatial-light-modulator controller is provided in a headlight controller 36, and controls the spatial light modulator 3. The spatial-light-modulator controller controls the spatial light modulator 3 so as to modulate the phase distribution of the laser light beam 10, and changes the light distribution pattern projected from the projection lens 5.

Abstract: Provided systems and methods for an aircraft lighting system (ALS) include a centralized blue generator that supplies blue light to a plurality (N) of passive light-heads distributed at various locations on the aircraft. A load profile for use of the N passive light-heads during all flight phases and operational phases is developed and uploaded into the system. Each of the passive light-heads is operationally coupled to the blue light generator via a respective light transmission element that is gated with a respective one of N light switches. A light generating control unit (LGCU) is coupled to the blue light generator, and controls the generation and actuation of blue light, in addition to controlling light switch positions, as a function of navigation data and the load profile. Each of the N passive light-heads comprises a respective light conversion element to convert the blue light into red, green, or white light.

Abstract: An illumination device comprises at least a laser (1) emitting a laser beam (6) of light of a first wavelength, a wavelength converting member (5) converting at least part of the light of the first wavelength into light of a second wavelength, a scanning unit (4) adapted to scan the laser beam (6) across the wavelength converting member (5) and an imaging optics (2) imaging a light emitting face of the laser (1) via the scanning unit (4) onto the wavelength converting member (5). In the proposed device, the laser beam (6) is guided via reflection at a reflective member (3) to the wavelength converting member (5). The reflective member (3) comprises a combination of at least a first and a second reflective element (8, 9), wherein the first and second reflective elements (8, 9) are formed and arranged such that the light emitting face of the laser (1) is imaged as a mirror-inverted image on the wavelength converting member (5) via the first reflective element (8) and as a non-mirror-inverted image via the second reflective element (9), both images being superimposed on the wavelength converting member (5). Due to this reflective member, intensity fluctuations in the image of the light emitting face on the wavelength converting member are reduced without enlarging the image.
