Aircraft disinfecting device

Abstract

The present invention provides a fixture or device which is particularly adapted for installation within the interior of a general aviation aircraft, such as a small private jet, prop-driven plane, helicopter, spacecraft, or other aviation vehicle. A plurality of UV-C lamps, typically LEDs are disposed within the fixture and project the radiance therefrom into the cabin, as well as control electronics to ensure safe emission limits by the LED. A temperature sensor minimizes LED burnout.

1 . An aircraft cabin interior UVC disinfecting device, comprising:
 a housing having an interior chamber, the housing having a surface facing the cabin interior, the surface having at least one first opening, a UV-C broad beam lamp disposed in the chamber and projecting through the first opening and at least on personnel detection sensor for detecting the absence or presence or motion of a human/animal mounted to the surface and means for controlling the irradiance level emitted by the LED lamp in response to the personnel detection sensor.   
     
     
         2 . The device of  claim 1  wherein the surface has a second opening, a UV-C narrow beam lamp disposed in the chamber and projecting its irradiance through the second opening. 
     
     
         3 . The device of  claim 1  which further comprises a pcBoard, a controller mounted to the pcBoard, the controller being in electrical communication with the lamps and the personnel detection sensor. 
     
     
         4 . The device of  claim 3  which further comprises a quartz lens covering the first opening and a Fresnel lens covering the second opening and wherein the second opening is larger than the first opening. 
     
     
         5 . The device of  claim 4  wherein the surface has a pair of first openings and a pair of broad beam LEDs mounted to the pcBoard, irradiance being projected through the pair of first openings. 
     
     
         6 . The device of  claim 1  wherein the personnel detection sensor is a LIDAR sensor. 
     
     
         7 . The device of  claim 1  wherein the personnel detection sensor is a PIR sensor. 
     
     
         8 . The device of  claim 1  which further comprises means for emitting an audible signal. 
     
     
         9 . The device of  claim 1  which further comprises at least one status indicator to signal the operational status of the device. 
     
     
         10 . The device of  claim 1  which further comprises means for controlling the temperature of the lamps, the means being incorporated into the controller. 
     
     
         11 . The device of  claim 1  which further comprises at least a pair of narrow beam LED lamps and a pair of broad beam LED lamps. 
     
     
         12 . The device of  claim 1  which further comprises an ultrasound sensor.
