A control device of a vehicle lamp device includes a reception unit and a control unit. The control unit includes a timing determination unit configured to determine a driving timing of an actuator configured to change a posture of the vehicle lamp device. The timing determination unit drives the actuator when an acquisition number of the output values of the acceleration sensor reaches a first number while a vehicle speed is less than a predetermined value, and drives the actuator when the acquisition number of the output values of the acceleration sensor reaches a second number smaller than the first number while the vehicle speed is equal to or greater than the predetermined value.

When it is determined on the basis of a captured image that a preceding vehicle is present, among a plurality of light that irradiates a target region in a plurality of divided regions ahead of a vehicle with light, a light source whose target region is a region where the preceding vehicle is present is controlled in such a manner as to block or attenuate light to the target region. A light source whose target region is a region where the obstacle is estimated to be present is controlled in such a manner as to irradiate the target region with light even when the preceding vehicle is present in the target region.

In a headlight optical-axis control device 10, a controller 15 is configured to: calculate vehicle angles indicating tilt angles of a vehicle relative to a road surface, on the basis of ratios, each being a ratio of a difference between a reference acceleration in a longitudinal direction and a signal indicating an acceleration in the longitudinal direction detected during traveling of the vehicle, to a difference between a reference acceleration in a perpendicular direction and a signal indicating an acceleration in the perpendicular direction detected during traveling of the vehicle by an acceleration sensor 2; calculate a plot of the calculated vehicle angles thereby to derive a vehicle angle corresponding to a case where a change of the acceleration in the longitudinal direction is zero; and generate a signal for controlling the optical axes of headlights 5L and 5R on the basis of the derived vehicle angle.

An illumination apparatus for a vehicle includes a projector configured to project an image of visible light; and a processing apparatus configured to predict a travel area of the vehicle after a predetermined time or a predetermined distance of travel, and project an image in the predicted travel area with the projector for illumination of the travel area, the image being indicative of a travel state of the vehicle or a control state of the vehicle.

An illumination apparatus having scanning laser source and a vehicle headlight using the illumination apparatus includes a light source, a wavelength converting member and a mirror mounted on a movable frame unit configured to rotate the mirror about two orthogonal axes. Light emitted by the light source is reflected by the mirror such that rotation of the mirror by the movable frame unit scans the reflected light in two directions at a substantially right angle with respect to each other and/or direct the reflected light towards the wavelength converting member to provide various color lights. The movable frame unit might be actuated by an AC voltage having a low frequency.

The optical system being associated with the LED group for shaping an output light intensity distribution from the light emitted by the LED group and the LED group and the optical system are stationary within the dynamic exterior aircraft light unit.

A lighting module for use in a lighting device for a vehicle includes at least one projection module for generating a light distribution in the vehicle's environment. At least one light source module is also provided. The projection module contains numerous projection units. The light source module contains numerous light source units. Each projection unit contains at least one projection lens. Each projection unit is dedicated to at least one light source unit.

A headlight system for a banking vehicle is provided. The headlight system includes a plurality of optical assemblies being arranged about an optical horizon and an optical vertical axis. Each of the plurality of optical assemblies includes an illumination source and an optical element. Each of the illumination sources is configured to direct light toward a corresponding one of the optical elements to produce an illumination region. The illumination regions combine to form an illumination pattern that includes at least one illumination region that is radial and is positioned relative an optical origin. The intersection between the optical horizon and the optical vertical axis defines the optical origin.

A headlight control apparatus (1) for performing control on a headlight device (7) which includes a pair of headlight units (3, 5) each including a light source (9) and an image forming section (16R, 16G, 16B) capable of forming an image and disposed in a light path of light from the light source to illuminate light (101, 105) for projecting the image onto a road surface, wherein the headlight control apparatus forms the image in the image forming section such that a first image (103) projected onto the road surface by one of the headlight units includes a second image (107) projected onto the road surface by the other headlight unit.
