A headlight for vehicles, having a light source unit for emitting light, an optical unit for deflecting the light in accordance with a predefined light distribution, and a control unit for generating a control signal, by means of which the light source unit and/or the optical unit can be controlled, wherein the control signal is generated depending on a number of environmental parameters, wherein an optimization program is stored in the control unit, by means of which optimization program the control signal is calculated from a plurality of individual control signals, wherein by means of the individual control signals different partial light distributions, each dependent on the environmental parameters, can be generated.

The present disclosure relates to an illumination system for a motor vehicle for illuminating a carriageway section. The aim is to illuminate the carriageway section in such a way that irritations for other road users are avoided as far as possible. The illumination system includes an information system for providing or detecting a stopping point, an illumination device for projecting a calculated light distribution onto the carriageway section, and a control unit for calculating a light distribution, wherein the calculated light distribution is a one-piece area. The one-piece area begins from a predetermined starting section, which constitutes a proximal lighting section relative to the motor vehicle and does not extend beyond the stopping point. This leads to a shortening of a lane light of the motor vehicle, so that said lane light does not illuminate the lane beyond the stopping point. This is advantageous in particular for crossroads.

The present disclosure described herein, in general, relates to a system 500 for controlling headlamps of a vehicle. The system 500 may comprise a signal processing unit 509, a relay circuit 401, a switch 302 and a user device 407. The user device 407 comprises a GPS tracker 408-A, an output unit 409, a processor 408-B and a memory 408-C. The system comprises comparing one or more parameters with the predefined threshold value, notifying information based upon the one or more parameters, instructing the user to change the status of the headlamp using the switch 302 based upon the comparison of the one or more parameters with the predefined threshold value and controlling the status of the headlamps upon receiving command by the user based upon the instructions or automatically operating the relay circuit 401 based upon the received signals.

A method for activating at least one device from a transportation vehicle wherein the at least one device is activated by the transportation vehicle at least as a function of global position data of at least one pedestrian and/or at least one cyclist. The position data of the at least one pedestrian and/or the at least one cyclist is transmitted to a remotely located computer unit and is made available to a computer unit of the transportation vehicle. The activation of the at least one device as a function of the position data of pedestrians and/or cyclists is made possible in a simple and economic way.

A lighting ECU determines whether or not a road sign relating to an urban area or a residential area is detected, while it is performing an automatic high beam control. When the detected road sign is a road sign indicating a start point of the urban area or of the residential area, the lighting ECU terminates the automatic high beam control, and maintain a light distribution pattern to a pattern corresponding to low beam. The lighting ECU restarts the automatic high beam control, when the detected road sign is a road sign indicating an end point of the urban area or of the residential area.

The invention relates to a method for operating a headlight (12) of a motor vehicle (10), which headlight (12) comprises a plurality of light emitting diodes, by receiving a request signal for a high-beam mode; determining a road class of a roadway on which the motor vehicle (10) is located; activating a first group of the plurality of light emitting diodes for providing a first high-beam distribution (20) with the headlight (12) in the event that a road class different from a highway (18) is determined; and activating a second group of the plurality of light emitting diodes for providing a second high-beam distribution (26) with the headlight (12) in the event that a highway (18) is determined as the road class.

A digital micro-mirror device (DMD) system capable of increasing a lifespan of a digital micro-mirror. The DMD system includes an array unit that includes a plurality of digital micro-mirrors, and a DMD controller that controls the digital micro-mirror according to an image signal input from the outside, and changes a duty ratio of the digital micro-mirror according to a condition of components included in a vehicle or an environment around the vehicle.

A method includes: recognizing a signal candidate position around a vehicle by using a sensor mounted on the vehicle, the signal candidate position being a position a traffic light is possibly present, the vehicle including a light configured in such a manner that a light distribution state of the light changes; and performing a first light control process of controlling the light in response to recognition of the signal candidate position, the first light control process including at least one of: increasing an intensity of light emitted to the signal candidate position to a value higher than before the recognition of the signal candidate position; or making the intensity of the light emitted to the signal candidate position higher than an intensity of light emitted to an area other than the signal candidate position.
