Abstract:
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.
