Abstract
Embodiments provide improved devices, systems, and methods of disinfection that use ultraviolet light, specifically, far UV-C light, to kill or deactivate microbes or allergens that are present on various types of surfaces and/or in the air.
Claims27
1-17. (canceled)
The germicidal lamp system of claim 19, wherein the light emitter and the electrical controller are positioned within a housing;
- and further comprising:
- the housing including a front housing and a back housing, the front and back housings being configured to contain electrical components of an ultraviolet luminaire;
- and
- a light shield, formed in one or both of the front housing and back housing and configured to substantially prevent heat and ultraviolet light produced by the ultraviolet emitter from reaching the electronic controller.
A germicidal lamp system configured to output ultraviolet illumination into a defined treatment area at least intermittently occupied by one or more humans, comprising:
- a light emitter configured to output ultraviolet light into a defined treatment area;
- a sensor configured to detect the presence of a human in the defined treatment area;
- and
- an electrical controller operatively coupled to the light emitter and the sensor, and configured to control the light emitter responsive to a signal from the sensor indicating the presence of a human in the treatment area.

36-39. (canceled)
A portable germicidal lamp system, comprising:
- a housing;
- a UV-C light source disposed in the housing and configured to output ultraviolet light into a space at least intermittently occupied by one or more persons;
- power supply configured to provide AC waveform to the UV-C light source;
- and
- an exposed interface configured to receive actuation to couple the power supply to the UV-C light source.
(canceled)
An auto-ranging UV-C source, comprising:
- a housing;
- an excimer light source disposed in the housing and configured to output UV-C light to kill pathogens in an exposure space having a centerline and extending away from the housing;
- an electronic controller disposed at least partially in the housing and operatively coupled to the excimer light source;
- and
- a distance sensor operatively coupled to or integrated with the electronic controller, the distance sensor being aligned to the centerline of the exposure space and configured to measure one or more distances from the housing to a surface bounding the exposure space, a person in the exposure space;
- or to the surface and the person;
- wherein the electronic controller is configured to receive data corresponding to the one or more distances from the distance sensor and to control the excimer light source to control a UV-C power intensity according to a pre-determined exposure limit at the person, the surface, or the person and the surface.
