Abstract
An aircraft lighting system includes quantum dot light-emitting diodes (“QLEDs”), including a first QLED of a first color and a second QLED of a second color. The system also includes logic circuitry configured to control the QLEDs to emit light in a first brightness ratio to create a light of a first metamer of a color and control the QLEDs to emit light in a second brightness ratio to create a light of a second metamer of the color.
Claims20
A aircraft cabin lighting unit comprising:
- a plurality of quantum dot light-emitting diodes (“QLEDs”), including a first QLED of a first color and a second QLED of a second color;
- and
- logic circuitry configured to carry out actions comprising:
- controlling the plurality of QLEDs to emit light in a first brightness ratio to create a light of a first metamer of a color, and
- controlling the plurality of QLEDs to emit light in a second brightness ratio to create a light of a second metamer of the color.
A lighting system for an aircraft cabin, the lighting system comprising:
- a cluster of quantum dots located on or near a visible surface within the aircraft cabin;
- a lighting device configured to emit light of a wavelength that is sufficient to excite the quantum dots to a state in which the quantum dots illuminate;
- and
- logic circuitry configured to control the lighting device to emit the light on a predetermined condition, thereby causing the quantum dots to illuminate.
A method for controlling quantum dot light-emitting diodes (“QLEDs”) in an aircraft cabin lighting unit, the method comprising:
- logic circuitry controlling a plurality of QLEDs to emit light in a first brightness ratio to create a light of a first metamer of a color;
- and
- the logic circuitry controlling the plurality of QLEDs to emit light in a second brightness ratio to create a light of a second metamer of the color,
- wherein the plurality of QLEDs includes a first QLED of a first color and a second QLED of a second color.
