1. An 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;
one or more light-emitting diodes (“
LEDs”
); and
logic circuitry configured to;
control the plurality of QLEDs to emit light in a first brightness ratio to create a light of a first metamer of a color,control the plurality of QLEDs to emit light in a second brightness ratio to create a light of a second metamer of the color, andcontrol the LEDs to operate in conjunction with the plurality of QLEDs to create the light of the first metamer of the color and to create the light of the second metamer of the color.

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.

10. 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. - View Dependent Claims (11, 12, 13, 14)
