Patent granted for vehicular lamp system with variable light distribution
A recently granted patent (Publication Number: US11964608B2) discloses a vehicular lamp system that includes a first lamp unit and a second lamp unit capable of forming light distribution patterns of variable intensity. The system also features a light distribution control device that adjusts the formation of light patterns based on targets detected by an imaging device. The control device can create high-illuminance patterns in regions without targets, shading patterns for forward vehicles, and mid-illuminance patterns for specific targets, by controlling the first and second lamp units independently.
Furthermore, the patent describes a method for controlling the formation of light distribution patterns by the lamp units based on the presence or absence of specific targets in the image captured by the imaging device. The method involves adjusting the illuminance of the patterns formed by the lamp units to create high-illuminance, shading, and mid-illuminance patterns as required. This innovative system allows for precise control of light distribution in vehicles, enhancing visibility and safety on the road.
