Abstract
A lighting unit may include a first light-emitting diode (“LED”), a second LED, and a third LED. The first LED may be configured to emit first electromagnetic radiation having a first wavelength of between about 600 nanometers (“nm”) and about 740 nm, the second LED may be configured to emit second electromagnetic radiation having a second wavelength of between about 500 nm and about 565 nm, and the third LED may be configured to emit third electromagnetic radiation having a third wavelength between about 315 nm and about 430 nm. Thus, the third electromagnetic radiation may be disinfecting UV-A radiation that is incorporated into a lighting unit that produces visible light.

- a second LED configured to emit second electromagnetic radiation having a second wavelength of between about 500 nm and about 565 nm;
- and
- a third LED configured to emit third electromagnetic radiation having a third wavelength between about 315 nm and about 430 nm.
A lighting assembly comprising:
- a lighting unit comprising:
- a first light-emitting diode (“LED”) configured to emit first electromagnetic radiation having a first wavelength of between about 600 nanometers (“nm”) and about 740 nm;
- a second LED configured to emit second electromagnetic radiation having a second wavelength of between about 500 nm and about 565 nm;
- and
- a third LED configured to emit third electromagnetic radiation having a third wavelength between about 315 nm and about 430 nm;
- and
- circuitry electrically coupled to the lighting unit and configured to drive relative intensity outputs of the respective LEDs of the lighting unit.
A lighting system for an aircraft, the lighting system comprising:
- at least one lighting unit disposed in a cabin of the aircraft, the at least one lighting unit comprising:
- a first light-emitting diode (“LED”) configured to first emit electromagnetic radiation having a first wavelength of between about 600 nanometers (“nm”) and about 740 nm;
- a second LED configured to emit second electromagnetic radiation having a second wavelength of between about 500 nm and about 565 nm;
