Abstract
A vehicle air purification system has a photocatalyst activated by photons emitted via an ultraviolet light emitting diode (UV-LED). The photocatalyst on a supporting structure is positioned to contact airflow passing through or over the photocatalyst. Chemical contaminants and microorganisms are eliminated from the airflow that makes contact with the photocatalyst structure.
Claims20
A transportation vehicle air purification system comprising:
- a housing having inlet and outlet for the air to be purified to enter and leave the housing;
- an ultraviolet light emitting diode (UV-LED) that is arranged to emit ultraviolet (UV) radiation;
- and
- a photocatalyst structure disposed in a distance from the UV-LED, wherein:
- the photocatalyst structure is placed inside of the housing,
- the UV LED is positioned to emit ultraviolet radiation onto the photocatalyst structure, and
- the photocatalyst structure is positioned to contact airflow passing through or over the photocatalyst structure.
4 more elements
A method of purifying airflow in transportation vehicles, comprising:
- passing the airflow through a reactor including one or more photocatalyst structures;
- emitting ultraviolet radiation from one or more ultraviolet light emitting diodes (UV-LEDs) onto the photocatalyst structure;
- and
- eliminating chemical contaminants and microorganisms from the airflow that makes contact with the photocatalyst structure while the photocatalyst is activated by the ultraviolet radiation emitted from the UV-LED.
