A lighting device comprises a light-emitting module with light-emitting elements, wherein the light-emitting elements are arranged adjacent to each other and are configured to emit light towards a light-emitting side. The light-emitting module is configured such that the light-emitting elements can be addressed partially independently of each other, such that some may be brought into a switched-on state while others are brought into a switched-off state. A top layer is disposed on the light-emitting module at the light-emitting side. Further comprising a switching material capable of a reversible change in transmittance for the light emitted by changing to a higher transmittance in regions where the top layer situated on light-emitting elements in the switched-on state or to a lower transmittance in regions of the top layer situated in the switched-off state. The invention further refers to methods for producing and operating a lighting device and using a lighting device.

A method for regulating a brightness of a luminous unit includes regulating the luminous unit by a pulse width modulator which provides an electric current having a predefined current value Y at a start time t0; modulating the electric current to a predefined brightness value at the start time t0 with a frequency of switching pulses that is chosen depending on a predefined brightness value; and progressively reducing the current value of respective switching pulses of the pulse-width-modulated electric current to a current value Y′ proceeding from a start time t0 until a target time t1. The current value Y′ is chosen in such a way that the luminous unit is luminous with the predefined brightness value upon a permanent supply with an electric current corresponding to the current value Y′. The respective switching pulses of the electric current are lengthened in their duration until a continuous electric current arises.

Provided herein is a headlamp assembly comprising a housing that encloses: a sensor that acquires data associated with a surrounding environment; a light source that illuminates a field of view comprising a portion of the surrounding environment; and one or more processors that analyze the acquired data and determine a direction, field of view, power, or an intensity of the illumination of the portion based on the analyzed data.

A vehicle lamp comprises a light source for road surface drawing configured to emit light becoming a light source image, and a projection lens, which has an optical axis extending in a front and rear direction and the light is to pass therethrough. The vehicle lamp can form a plurality of light distribution patterns on a road surface over a range from a position close to the lamp to a position distant from the lamp by the light emitted from the light source and having passed through the projection lens, and the respective light distribution patterns are to be projected on the road surface at states where relative positions between the projection lens and the light source image are different.

This vehicular lighting equipment provided on a vehicle (100), which is capable of travelling around a corner by tilting the vehicle body toward the turning direction, comprises a light source, an optical member by which the light emitted from the light source is directed forward from the lighting equipment to form a predetermined light distribution pattern (PL), and a control unit for adjusting the predetermined light distribution pattern (PL) according to the tilted state of the vehicle body. The control unit is configured to adjust a predetermined light distribution pattern (PL2) such that in a light distribution pattern (PL1) corresponding to when the vehicle body is tilted, no light is irradiated in a region located outside the light distribution pattern (PL) corresponding to when the vehicle body is in the vertical state.

A method for aligning an illuminated area of a headlight of a vehicle as a function of the surroundings of the vehicle, includes classifying at least one other vehicle in the surroundings of the vehicle as a function of a piece of information concerning a position of the other vehicle in relation to the vehicle, determining a target position of the headlight, with disregard of the other vehicle, when the other vehicle is classified as passing the vehicle or as being passed by the vehicle, and providing a signal for moving the headlight into the target position while the vehicle is being passed by the other vehicle or is passing the other vehicle.

An illuminating device includes a detecting section configured to detect a vehicle height of a forward vehicle running in front of a vehicle; and a control section configured to control an illuminating range of a head lamp of the vehicle according to the vehicle height.
