The lighting device for a vehicle has two light sources and a wavelength conversion device excited by the combination of the radiations from the two light sources. A first light source is associated with a scanning system projecting, by scanning, a first light radiation onto a first conversion region of the device, while a second light source with semiconductors emits a second light radiation into a second conversion region of the device. The second source, different from the first source and whose luminance level is typically less high, is provided with light-emitting units of submillimetric dimensions. The beams produced by the device respectively in the first region and in the second region have different characteristics and complement one another to produce one or more lighting functions.

A system mounted on a vehicle for detecting an obstruction on a surface of a window of the vehicle, a primary camera is mounted inside the vehicle behind the window. The primary camera is configured to acquire images of the environment through the window. A secondary camera is focused on an external surface of the window, and operates to image the obstruction. A portion of the window, i.e. window region is subtended respectively by the field of view of the primary camera and the field of view of the secondary camera. A processor processes respective sequences of image data from both the primary camera and the secondary camera.

There is provided a lighting device arranged to produce a controllable light beam for illuminating a scene. The device comprises an addressable spatial light modulator arranged to provide a selectable phase delay distribution to a beam of incident light. The device further comprises Fourier optics arranged to receive phase-modulated light from the spatial light modulator and form a light distribution. The device further comprises projection optics arranged to project the light distribution to form a pattern of illumination as said controllable light beam.

A vehicle lamp includes: a variable light distribution lamp capable of generating a beam having a variable intensity distribution; an infrared illumination device configured to irradiate a front; an infrared camera configured to image the front; and a light distribution controller configured to detect a snow particle based on an output of the infrared camera, generate a light distribution pattern in which a portion corresponding to the snow particle is shaded, and control the variable light distribution lamp.

A vehicle lamp includes: a light distribution controller configured to generate a light distribution pattern including a shaded portion in which a margin region is added around a snow particle; and a variable light distribution lamp capable of generating a beam having an intensity distribution corresponding to the light distribution pattern. And at least one of a size and a shape of the margin region is variable.

A vehicle headlight device attached to a part of a vehicle and configured to apply illumination light to a road surface on which the vehicle runs comprises: a light source device configured to Generate the illumination light; an optical unit disposed on a light axis of the light source device and configured to project the illumination light from the light source device so as to form a desired light distribution; and a polarization direction conversion device disposed in a part of a light path between the light source device and the optical unit and being able to control the illumination light from the light source device with inclusion of conversion of a polarization direction thereof for each irradiation region in accordance with a state of a position irradiated with the illumination light on the road surface.

A vehicle lighting device is provided which improves overlooking of pedestrians by a driver even under adverse conditions such as nighttime and rainy weather. A vehicle lighting device includes: a low-beam irradiation part that illuminates a lower irradiation region ahead and below a vehicle: a pattern irradiation part that irradiates irradiation light on a lateral irradiation region on a side of the travel path of the vehicle in an irradiation pattern in which bright regions and dark regions are alternately repeated; an environmental information acquisition device which acquires information related to the moisture environment around the vehicle; and a controller which changes the irradiation mode of the low-beam irradiation part and/or pattern irradiation part based on information acquired by the environmental information acquisition device. In one mode, the controller dims irradiation light in the low-beam irradiation part, and brightens irradiation light in the pattern irradiation part when rainy weather at night.

A variable beam pattern lamp system for a driver provides an input device that receives personal information of the driver, a lamp driving device that drives an indoor or outdoor lamp of a vehicle to output a beam pattern matched to the driver, based on the personal information of the driver, the personal information being input through the input device, and a vehicle controller that determines whether the personal information is registered driver information or unregistered driver information, when the personal information of the driver is input through the input device, and controls the lamp driving device to drive the indoor or outdoor lamp of the vehicle using beam patterns respectively corresponding to that the personal information is the registered driver information and that the personal information is the unregistered driver information.

A method for adjusting vehicle lighting when driving through a building site involves adjusting a light pattern cast by at least one vehicle headlight into an environment from a top light field, referred to as high beam, and a bottom light field, referred to as low beam, upon recognizing that a building site is being driven through by changing a light intensity with which the light pattern is generated. The light intensity at which the low beam is emitted is increased to a determined value when driving through the building site.

Method and apparatus are disclosed for control of vehicle headlights based on weather conditions. An example vehicle includes headlamps including low-beam lamps and high-beam lamps. The example vehicle also includes a light sensor, a camera, and a controller. The controller is to set the low-beam lamps in active mode when the light sensor detects low ambient light, monitor for precipitation in the low ambient light via the camera, identify an angle-of-incidence (AOI) between the precipitation and light emitted by the headlamps, and control the high-beam lamps based on the AOI.
