Abstract
A lighting system that comprises a chromic dye applied to a lens of a light assembly. The chromic dye is configured to transition between different optical states in response to trigger stimuli.
Claims9
A lightbar of a vehicle comprising:
- a light assembly that comprises at least one light source to emit light within an emission spectrum;
- a lens positioned in front of the at least one light source;
- and
- a chromic panel that comprises a photochromic surface that comprises a suspended particle device (SPD) film applied directly to a surface of the lens, the chromic panel comprising a photochromic dye that comprises a sensitizer that possesses an enhanced sensitivity to a specific wavelength of light within the emission spectrum of the light emitted by the light source, wherein the sensitizer comprises an absorption spectrum that is substantially equivalent to the emission spectrum of the light emitted by the light source, and wherein the photochromic dye comprises a chemical composition that includes at least one functional group designed to enhance sensitivity of the photochromic dye to the emission spectrum of the light source, to cause a property of the chromic panel to transition between a first state that comprises an opaque state and a second state that comprises a transparent state responsive to a trigger stimulus that comprises the specific wavelength of the light emitted by the light source, wherein the chromic panel adapts automatically without external sensors or control mechanisms.

The lighting system of claim 8, wherein the sensitizer includes at least one functional group to enhance sensitivity of the chromic surface to the emission spectrum of the light.
-14. (canceled)
A method of operating a lightbar of a vehicle comprising:
- providing a light assembly that comprises at least one light source, a lens, and a chromic panel that comprises a photochromic surface that comprises a suspended particle device (SPD) film applied directly to a surface of the lens, the chromic panel comprising a sensitizer that possesses an enhanced sensitivity to a specific wavelength of light within the emission spectrum of the light emitted by the at least one light source, wherein the sensitizer comprises an absorption spectrum that is substantially equivalent to the emission spectrum of the light emitted by the light source, and wherein the photochromic dye comprises a chemical composition that includes at least one functional group designed to enhance sensitivity of the photochromic dye to the emission spectrum of the light source, to cause a property of the chromic panel to transition between a first state that comprises an opaque state and a second state that comprises a transparent state based on a trigger stimulus that comprises the specific wavelength of the light emitted by the light source, wherein the chromic panel adapts automatically to operational conditions without the need for external sensors or additional control mechanisms;
- detecting the trigger stimulus that influences the photochromic dye of the chromic panel;
- and
- transitioning the chromic panel from the first state to the second state responsive to the trigger stimulus.
