A method for controlling a light pattern provided by an automotive lighting device of an automotive vehicle. The method includes providing a road profile, extracting road features from the road profile, dividing the matrix arrangement in row groups, assigning a different shifting value for each row group, each shifting value depending on the road features and dividing each row group in at least a first portion and a second portion. Each portion includes at least a boundary pixel which is in contact with the boundary pixel of an adjacent portion. The method further includes modifying the width of the first portion and the width of the second portion by shifting the position of the boundary pixels in each row group according to the corresponding shifting value and interpolating the luminous intensity values of the pixels belonging to the first and second portion.

A vehicle lamp includes: at least one light source configured to generate light; a first reflector configured to reflect the light generated by the at least one light source; a shield configured to block a first portion of light reflected from the first reflector, and to transmit therethrough a second portion of the light reflected from the first reflector to form a beam pattern; a lens; and a second reflector configured to: in a first state, reflect light that was reflected from the first reflector back toward the first reflector; and in a second state, reflect light that was generated by the at least one light source to be incident on the lens, wherein the second reflector is configured to rotate about an axis and cause the vehicle lamp to output in a low-beam mode or in a high-beam mode based on a rotational orientation of the second reflector.

A light distribution method is for an adaptive driving beam headlamp system including a light emitting device, an on-board camera and an electronic control unit. The light distribution method includes: obtaining data indicative of a state in front of a vehicle by the on-board camera; computing one or more of: attributes of an object in front of the vehicle; attributes of a vehicle ahead; a speed of the vehicle ahead; a distance between vehicles; brightness of the object; and a road shape; determining a light distribution pattern; determining a control amount indicative of at least one of an ON or OFF state of each of the light emitting elements and an applied power to each of the light emitting elements according to the light distribution pattern determined; and controlling driving of the adaptive driving beam headlamp system based on the control amount determined.

In a light control device, positional information of another vehicle present near an own vehicle is acquired. An irradiation area is set based on the position of the other vehicle. Output for changing the irradiation area of a light in the own vehicle is performed to achieve the set irradiation area. The output for changing the irradiation area is prohibited until the elapse of a wait time that has been set in advance are included. According to the light control device, the irradiation area of the light is not changed until the elapse of the wait time. Therefore, annoyance caused by the irradiation area being frequently changed can be suppressed.

An adaptive light module for incorporation into a vehicle's headlight assembly is provided, where the light module may be incorporated as a single unit, or incorporated as one of a plurality of units. The light module, which uses an LED array, collimating optics, illumination and projection micro-lens-arrays (HLAs), is configured to allow tailoring of the illumination intensity distribution by selectively activating/deactivating subsets of the LED array.
