Adaptive anti-glare light system and associated methods
First Claim
1. A method of adapting light to environmental conditions as a countermeasure to glare using a lighting device that includes a sensor, a color selection engine operatively coupled to the sensor, a controller operatively coupled to the color selection engine, and a plurality of light sources each configured to emit a source light in a source wavelength range, wherein each of the plurality of light sources is operatively coupled to the controller, wherein at least one of the plurality of light sources is a white light, the method comprising:
- emitting a first light;
receiving a reflected light comprising a detected color;
determining if the detected color is characterized by a discomfort glare rating below a threshold level;
determining a dominant wavelength of the detected color that is characterized by the discomfort glare rating of the detected color being below the threshold value;
determining a combination of at least two of the plurality of light sources that emit a combined wavelength that approximately matches the dominant wavelength of the detected color; and
operating the combination of at least two of the plurality of light sources to emit the combined wavelength to be defined as an adapted light that has a discomfort rating at or above the threshold value, wherein at least one of the plurality of light sources is the white light.

Abstract
An adaptive anti-glare light system including a sensor, a color selection engine, a controller, and a plurality of light sources each configured to emit a source light. The sensor transmits a source color signal designating a reflected light characterized by a detected color and a discomfort glare rating. The color selection engine determines a dominant wavelength of the detected color, and a combination of the light sources that the controller may operate to emit a combined wavelength that matches the dominant wavelength of the detected color. A method of adapting light as a countermeasure to glare comprises receiving the detected color, determining a subset of the plurality of light sources that may be combined to form an adapted light that matches the detected color, and operating the light sources with a white light to emit the adapted light at or above a threshold discomfort glare level.
