Abstract
Dimmable external vehicle lighting and methods of use are provided herein. An example method includes determining environmental light intensity around a vehicle, determining a luminance of an external light of the vehicle, determining a difference in magnitude between the environmental light intensity and the luminance of the external light, and selectively adjusting the luminance of the external light based on the difference.
Claims20
A method, comprising:
- determining environmental light intensity around a vehicle;
- and
- selectively adjusting luminance of a plurality of elements of an external light of the vehicle as the environmental light intensity changes so as to reduce power consumption by the external light, wherein a first segment of the plurality of elements is dimmed to greater degree than a second segment of the plurality of elements.
A system, comprising:
- a headlight of a vehicle;
- and
- a light controller that controls the headlight of the vehicle, wherein the light controller comprises:
- a processor;
- and
- a memory for storing instructions, the processor executing the instructions to:
- determine environmental light intensity around a vehicle;
- and
- incrementally adjust luminance of a plurality of elements of the headlight as the environmental light intensity changes so as to reduce power consumption of the headlight, wherein a first segment of the plurality of elements is dimmed to greater degree than a second segment of the plurality of elements.
6 more elements
A method, comprising:
- determining environmental light intensity in a location where a vehicle is operating;
- determining a luminance of an external light of the vehicle;
- and
- selectively adjusting the luminance of the external light when the vehicle is within a specified distance from, and behind, an adjacent vehicle, or based on a comparison between the environmental light intensity and the luminance of the external light.
