An adaptive lighting system for an automotive vehicle. The adaptive lighting system has a wavelength conversion device for receiving the light radiation (L) from the primary source and re-emitting white light radiation (B). An optical imaging system receives the white light (B) re-emitted by the wavelength conversion device and projects this light (B) in front of the vehicle to form a lighting beam, the wavelength conversion device being situated close to a focal plane of the optical imaging system, and the scanning system and the optical system being situated on the same side or on opposite sides of the wavelength conversion device. An intensity of the white light radiation (B) emitted by the wavelength conversion device is capable of being modulated between a minimum value and a maximum value, and the scanning is performed at variable speed.

A method for adjusting a light-level of at least one headlamp for a vehicle. The method includes a reading in; a determining; an ascertaining; and a providing. In the reading in, a position-signal is read in, which represents the current-position of the vehicle. In the determining, a topography-signal is determined using the position-signal, which represents a stored item of information about a roadway-topography at the current position, especially in the case of a curvature and/or a drop of a roadway. In the ascertaining, an angle of inclination of the headlamp to be adjusted for the optimal illumination of the roadway in front of the vehicle is ascertained using the topography-signal. In the providing, an actuating-signal is provided for an adjustment mechanism of the headlamp using the ascertained-angle of inclination to tilt the headlamp to the ascertained-angle of inclination so that the light level of the headlamp is adjustable.

An apparatus for controlling a vehicle light with adjustable light output is provided, whereby the apparatus includes a processor configured to receive on-board diagnostics (OBD) data and to determine a light output mode for the vehicle light in accordance with the OBD data, whereby the OBD data indicates a vehicle condition. The apparatus includes a transceiver coupled to the processor that is configured to signal the light output mode to the vehicle light. A method of controlling a vehicle light is provided that includes receiving OBD data from an OBD system in a vehicle, whereby the OBD data determines a vehicle condition, determining a light output mode of the vehicle light in accordance with the OBD data, and sending to the vehicle light appropriate commands for adjusting the light output in accordance with the determined light output mode.

An illumination apparatus that illuminates an illumination zone having a first direction and a second direction crossing the first direction is provided with a light source to emit a coherent light beam, and a diffraction optical device to diffract the coherent light beam incident from the light source. The diffraction optical device diffracts the incident coherent light beam so that a width of the illumination zone in the second direction gradually becomes wider along the first direction of the illumination zone from a nearer side to the diffraction optical device.

Each of a pair of (left and right) lamp modules is equipped with a first lamp unit having four first light sources and a second lamp unit having a single second light source, and a horizontally long first light distribution pattern or part of it is formed by selectively lighting one or more of the four first light sources. Furthermore, a second light distribution pattern that is smaller and brighter than the first light distribution pattern is formed by lighting the second light source. The first light distribution pattern and the second light distribution pattern are combined, whereby a high-luminous-intensity region is formed as an overlap of them. The first lamp unit and the second lamp unit are configured so as to be able to swing in a horizontal plane so that the high-luminous-intensity region can be shifted in the left-right direction according to a vehicle running situation.

A vehicle head lamp includes a spatial light modulator and a control device. The vehicle head lamp forms a desired light distribution pattern by radiating light forward via the spatial light modulator, a high luminous intensity region and a low luminous intensity region adjacent to an outer edge of the high luminous intensity region are formed in the desired light distribution pattern to be irradiated by controlling the spatial light modulator, the low luminous intensity region is configured such that the luminous intensity decreases gradationally from the outer edge of the high luminous intensity region toward an outside of the low luminous intensity region, and the control device controls the spatial light modulator so as to relatively change at least one of sizes, luminous intensities, and positions of the high luminous intensity region and the low luminous intensity region based on a traveling condition of a vehicle.

Method and electromechanical device (1) for stabilizing the front lighting of a motorcycle provided with a front lighting device (2). The electromechanical device (1) comprises a sensor set (3) for detecting the lateral tilting angle experienced by the motorcycle on taking a curve and a motor (4) to drive the gear system (8). The gear system (8) forces the lighting device (2) to turn a rotation angle that compensates the lateral tilting experienced by the motorcycle. In this way, by means of the electromechanical device (1) of the invention, an appropriate distribution of the front lighting of the motorcycle is maintained throughout the entire straight-line or curvilinear path, without the need to add additional lighting devices and in accordance with the prevailing regulation regarding front lighting devices.

A vehicular lighting apparatus is relatively small, low cost, superior in mountability, and offers a superior design. The vehicular lighting apparatus attachable to a front end of a vehicle includes: a composite lens element that is a light guide element constructed by molding a translucent resin substantially into a plate-like shape; a planar light-emitting unit that emits illumination light; an optical system that transforms planar light from the light-emitting unit into linear light and that causes the linear transformed light to be incident on a rear side face of the light guide element; and a diffraction lens formed on the rear side face of the light guide element on which the linear transformed light is incident, and condensing the linear transformed light. The light condensed by the lens means is emitted from a front side face of the light guide element onto a road surface in front of the vehicle.

A vehicular light switch can change the mode of an exterior-illuminating light by rotating to different positions including an auto setting and a SMALL setting. If the position of the vehicular light switch is rotated to the SMALL setting, a momentary mechanism returns the position to the auto setting. If extravehicular brightness is less than a prescribed value and the position is rotated to the SMALL setting whilst the vehicle is stationary, a first light controller turns off a low-beam light, and turns on the low-beam light if the vehicle runs afterwards. If extravehicular brightness is less than a prescribed value and the position is rotated to the SMALL setting while the vehicle is running, a second light controller keeps the low-beam light turned on.

A light projection method for a moving body which is performed by a processor of the moving body is provided. The method comprises: irradiating light from a light source of the moving body; scanning the light irradiated from the light source with an angle range that is formed by swing a mirror portion of an optical scanner of the moving body; acquiring change information of the angle range at which the mirror portion swings; changing the angle range at which the mirror portion swings based on the acquired change information; and changing an irradiation range of the light irradiated from the light source.
