Vehicle lighting system with reduced uneven brightness
A recently granted patent (Publication Number: US11859788B2) discloses a vehicle lighting system that includes a lamp unit and a control unit. The lamp unit consists of a light source, a liquid crystal element, and a lens that projects light onto the periphery of the vehicle. The control unit manages the operation of the lamp unit, ensuring that the light emitted from the source is incident on the liquid crystal element at a wide angle. The system allows for precise control of the light distribution by setting different voltages for specific regions on the light incident surface of the liquid crystal element.
Furthermore, the patent describes a vehicle lighting system with multiple lamp units in the front section of the vehicle, each equipped with a light source, a liquid crystal element, and a lens. The control unit independently manages the operation of each lamp unit, ensuring symmetrical light distribution. By setting different voltages for distinct regions on the light incident surface, the system can achieve a desired tone of irradiation light. Additionally, the patent details a configuration where the lamp units on the left and right sides of the vehicle have symmetrical viewing directions, enhancing the overall lighting symmetry of the vehicle.
