A vehicle headlamp includes a reflector having plural reflecting surfaces arranged in a left-right direction, and n light sources which are arranged in the left-right direction and emit light toward any one of the reflecting surfaces. At least two adjacent light sources are provided as a common light source which emits light toward a same reflecting surface. n illumination patterns which illuminate different regions in the left-right direction are formed by light emitted from the n light sources, respectively, and are taken as a first to n-th illumination patterns in this order in the left-right direction. At least half of areas of illumination patterns of an immediately-following number and an immediately-preceding number overlap each other in the left-right direction. Focal lengths of the plural reflecting surfaces are set such that adjacent illumination patterns which do not overlap each other are formed by light emitted from the common light source.

The invention is related to a method for controlling a light pattern provided by an automotive lighting device of an automotive vehicle, wherein a dynamic portion of the light pattern is provided at least by a matrix arrangement of light sources. This method includes the steps of sensing a turn in a steering system of the automotive vehicle, dividing the dynamic portion in a first portion and a second portion, shifting the operation of the light sources associated to the first portion in the same direction as the sensed turn and create a third portion between the shifted first portion and the second portion. The invention also provides an automotive lighting device with control means to perform the steps of the method.

The present invention relates to an optical element (1), an optical module and a vehicle. The optical element (1) comprises: a light incident section (10) for receiving light directly from a light source; a light exit section (30) having a focal plane (P); and a third section (20) that directs light from the light incident section (10) toward the light exit section (30) in a predetermined manner to generate a predetermined low beam distribution or high beam distribution, where the optical element (1) is implemented integrally.

A vehicle headlamp device to be applied to a vehicle includes a light source, a lens, and a controller. The light source is configured to emit light. Light emitted from the light source is to pass through the lens. The controller is configured to control light distribution patterns for the light. The light distribution patterns include at least a first light distribution pattern and a second light distribution pattern. The first light distribution pattern illuminates an area ahead of the vehicle during running of the vehicle. The second light distribution pattern is projected as a marking at an optical axis adjustment that is performed during manufacturing of the vehicle. The controller causes a part of the light source to emit light so that the second light distribution pattern is formed.

Each of a pair of left and right vehicle head lamps includes a plurality of optical units in a lamp chamber. A variable light distribution type optical unit that changes a light distribution mode of a high beam depending on a surrounding state and a traveling state of a vehicle is disposed in a first vehicle head lamp on a passenger seat side, and a figure drawing optical unit capable of forming a desired figure on a road surface in front of the vehicle by emitted light is disposed at a position symmetrical to the variable light distribution type optical unit in a second vehicle head lamp on a driver seat side.

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.
