Abstract
UV-C light assembly is designed to kill germs (bacteria, molds, protozoa, virus, and yeast) in the forced airstreams of HVAC systems, thus preventing the spreading of germs into other rooms or spaces. An air-flow activated switch is invented for turning on the UV-C lights when airstreams pass through and turning off when airstreams stop in the HVAC systems. The UV-C light assembly is installed inside duct through air filter's opening. The UV-C germicidal assembly is an easy add-on to an existing HVAC system for indoor air purification. The UV-C light sources are either LEDs or fluorescent tubes.
Claims10
An air-flow activated germicidal UV-C light fixture comprising a UV-C light source, an air-flow catching wind cup serving as an air-flow sensor and switch trigger on one end of a lever and NOPB (Normally Open Push Button Switch) on the other end, wherein air-flow pushes the wind cup to force the other end of the lever to press down the NOPB, and thus to close the electrical circuit and results in the turning on of the UV-C light, and then the UV-C light and the switch are mounted to the circuit housing, which is installed to a HVAC system.
