Vehicle light and method for controlling light distribution

A method for controlling a light distribution of a vehicle light, the method comprising:

• providing a vehicle light including a first nearby illumination unit configured to individually control light intensities of light beams for illuminating respective first nearby illumination areas, a first farther illumination unit configured to individually control light intensities of light beams for illuminating respective first farther illumination areas, a second nearby illumination unit configured to individually control light intensities of light beams for illuminating respective second nearby illumination areas, and a second farther illumination unit configured to individually control light intensities of light beams for illuminating respective second farther illumination areas, each illumination unit including a plurality of LED chips disposed horizontally and which serve as light sources configured to be individually controlled for activation, and a projection lens that is disposed in front of the plurality of LED chips and is configured to project light source images of the LED chips;
• acquiring data regarding a relevant vehicle at a predetermined timing, the data including at least one of an image of a relevant vehicle and a distance to the relevant vehicle;
• calculating a precise position and a precise distance of the relevant vehicle based on the acquired data;
• generating designation data for designating at least one LED chip of the illumination units based on calculation results including precise position and precise distance of the relevant vehicle;
• controlling the at least one LED chip designated by the generated designation data so that the designated LED chip is turned off or reduced in light intensity, thereby dimming a corresponding illumination area among the first nearby illumination areas, the first farther illumination areas, the second nearby illumination areas, and the second farther illumination areas;
• and
• projecting light beams from respective LED chips so that a synthetic light distribution pattern formed by overlaying the first nearby illumination areas, the first farther illumination areas, the second nearby illumination areas, and the second farther illumination areas is thus controlled, wherein respective vertical division lines of the illumination areas appear in predetermined order in a horizontal direction.

A vehicle light for forming a synthetic light distribution pattern, comprising:

• a first nearby illumination unit configured to control light intensity of light beams for illuminating a first nearby illumination area, the first nearby illumination area divided into horizontal regions;
• a first farther illumination unit configured to control light intensity of light beams for illuminating a first farther illumination area, the first farther illumination area divided into horizontal regions;
• a second nearby illumination unit configured to control light intensity of light beams for illuminating a second nearby illumination area, the second nearby illumination area divided into horizontal regions;
• and
• a second farther illumination unit configured to control light intensity of light beams for illuminating a second farther illumination area, the second farther illumination area divided into horizontal regions,
• wherein respective illumination areas have vertical division lines as edges of each of the areas, and
• wherein the first nearby illumination area, the first farther illumination area, the second nearby illumination area, and the second farther illumination area are overlaid so that respective vertical division lines of the illumination areas appear in a predetermined order in a horizontal direction.
