US Patent:

20190091358, Mar 28, 2019

Filed:

Nov 26, 2018

Appl. No.:

16/200190

Inventors:

- Hayward CA, US
Douglas A. Collins - Hayward CA, US
Theodore J. de Jony - Campbell CA, US
Robert C. Walker - Redwood City CA, US
Elaine Taylor - Hayward CA, US

International Classification:

A61L 2/10
H05B 33/08
C02F 1/32
C02F 1/00

Abstract:

A variety of applications for UV LEDs that are integrated into a system are described, where the UV light is used for disinfection of air or surfaces, or used to detect the scattering light by particles, or used for skin treatment. In one embodiment, a ceiling luminaire includes a sensor for detecting the presence of people in the room. The luminaire contains a first set of LEDs for generating white light, for illumination, and a second set of LEDs for generating UV light for disinfecting the room. When the sensor detects that no people are in the room, the system automatically controls the UV LEDs to turn on to disinfect the room. The white light LEDs may be independently controlled with a dimmer.

International Classification:

Abstract:

A variety of applications for UV LEDs that are integrated into a system are described, where the UV light is used for disinfection of air or surfaces, or used to detect the scattering light by particles, or used for skin treatment. In one embodiment, the UV light from the UV LEDs is generated internal to a housing and is optically coupled to a transparent or translucent surface touched by the human finger, such as a touch screen, a fingerprint scanner, backlit buttons or keys, a toggle of a light switch, a door knob, etc. The UV light is emitted through the touched surface to periodically disinfect the surface. A visual indication of the UV LEDs being energized is provided for safety, such as energizing visible light LEDs or a phosphor on a portion of the touched surface.
