LIGHTING DEVICE THAT PRODUCES A MAIN BEAM AND A NARROW BEAM THAT IS ORIENTABLE DEPENDING ON THE POSITION OF AN OBSTACLE DETECTED IN FRONT OF A VEHICLE
A vehicle equipped with analysing means that analyse a zone (ZA) located in front of the vehicle is equipped with a lighting device (DE). This device (DE) comprises:a first source (S1) that generates first photons and a reflector (RP) that reflects the first photons toward the zone (ZA) so that they form a first light beam (F1) that performs a photometric lighting function,a second source (S2) that is installed in front of a central portion (PC) of the reflector (RP) and that generates second photons,a lens (LF) that is inserted between the second source (S2) and the zone (ZA), that is positionable in various positions, and that forms, with the second photons, a second light beam (F2) that is narrow and that points toward a sub-zone of the one (ZA) that depends on a set lens position, andcontrolling means (MC) that set the position of the lens in case of detection of an obstacle in a sub-zone of known position.
LIGHT DISTRIBUTION CONTROL APPARATUS FOR VEHICLE
A light distribution control apparatus comprises an irradiating apparatus and an irradiation control apparatus. When a vehicle is travelling on an own lane, the irradiation control apparatus lightens a first region including a region right in front of the vehicle using the irradiating apparatus. When a request for lane change to a target lane occurs under a situation where the vehicle is travelling on the own lane, the irradiation control apparatus lightens a second region using the irradiating apparatus, the second region including a region-at-a-lane-change-side positioned at a target lane side with respect to the first region and a reduced region which is a region where the first region is reduced to a region near the vehicle as well as control the irradiating apparatus so that illuminance in the reduced region becomes less than or equal to illuminance in the reduced region before the request for lane change occurs.

LIGHT INTENSITY ADAPTIVE LED SIDEWALLS
A first pixel with a first pixel sidewall is disclosed. A second pixel with a second pixel sidewall facing the first pixel sidewall is also disclosed. A first dynamic optical isolation material between the first pixel sidewall and the second pixel sidewall and configured to change an optical state based on a state trigger such that a light behavior at the first pixel sidewall for a light emitted by one of the first pixel and the second pixel is determined by the optical state, is also disclosed.
Method for controlling a motor vehicle headlight
The invention relates to a method for controlling a motor vehicle headlight which at least comprises a laser diode (1) and a light conversion element (8) paired with the laser diode (1). Light conversion element (8) regions corresponding to different regions of the light image (11) can be illuminated periodically and with a varying intensity by means of a light beam (2) of the laser diode (1), and the illumination intensity in the light conversion element (8) regions corresponding to the different regions of the light image (11) is adjusted simultaneously by both the relative illumination duration of the different regions as well as different luminous intensities of the laser diode (1) in the light conversion element (8) regions corresponding to the different regions of the light image (11). In regions in which the light beam (2) is moved with an angular speed below a defined value for the angular speed, the laser diode (1) is solely deactivated and activated, and different luminous intensities of the laser diode (1) are set when the angular speed is above a defined value. The motor vehicle headlight according to the invention has a computing unit (4) for carrying out the method according to the invention.
