Abstract
A light assembly may comprise: a light array comprising a plurality of light emitting diodes (LEDs), each light emitting diode (LED) configured to emit an electromagnetic radiation having a wavelength, the wavelength of each LED being different, a first LED in the light array configured to emit a first wavelength between 414 nm and 474 nm; and a non-linear optical layer disposed adjacent to the first LED, the nonlinear optical layer configured to output the first wavelength and a second wavelength, the second wavelength being between 207 nm and 237 nm.

A light assembly comprising:
- a light array comprising a plurality of light emitting diodes (LEDs), each light emitting diode (LED) configured to emit an electromagnetic radiation having a wavelength, the wavelength of each LED being different, a first LED in the light array configured to emit a first wavelength between 414 nm and 474 nm;
- and
- a non-linear optical layer disposed adjacent to the first LED, the nonlinear optical layer configured to output the first wavelength and a second wavelength, the second wavelength being between 207 nm and 237 nm.
A sanitization system, comprising:
- a passenger service unit including a light assembly, the light assembly comprising:
- a first light emitting diode (LED) configured to emit a first electromagnetic radiation having a first wavelength;
- a second LED configured to emit a second electromagnetic radiation having a second wavelength;
- and
- a third LED configured to emit a third electromagnetic radiation having a third wavelength between 414 nanometers (nm) and 474 nm, the first wavelength and the second wavelength different from the first wavelength, the third LED in optical communication with a nonlinear optical layer, the nonlinear optical layer configured to output a portion of the third electromagnetic radiation as a fourth wavelength between 207 nm and 237 nm.
A method of retrofitting a first light assembly with a second light assembly having a sanitization system, comprising:
- decoupling a lens from the first light assembly in a passenger service unit (PSU);
- installing a second lens in the PSU to form the second light assembly, the second lens including a non-linear optical layer.
