Germicidal Lamp (e.g., Ultraviolet Light, Etc.) Patents (Class 96/224)
  • Patent number: 11850337
    Abstract: The present invention provides an air purifier that purifies, disinfect and decontaminate convention air flow by using UV rays. Because the UV rays emitted by the UV light sources are contained within the air purifier, use of the air purifier is safe in that a nearby person can avoid exposure to hazardous UV radiation. Adjustment of operating conditions, such as the UV intensity and wavelength and air speed, is programmable via a remote controller, a smart switch, a smart device, a wireless communication device, a smart home control appliance, a sensing device, and/or a built-in module, which renders the air purifier a smart appliance that may automatically and optimally suits to a user's need based on the user's habit and other physical parameters. Installation and removal of the air purifier, as well as cleaning and replacement of any part thereof, are simple and convenient, as a result of the clever design.

    Abstract: The present invention relates to an antimicrobial filter adopting optical fibers and to an air cleaner comprising the same. More particularly, the present invention relates to an antimicrobial filter using optical fibers and to an air cleaner comprising the same, in which ultraviolet rays, visible light or natural light is emitted directly through the surface of optical fibers contained in a filtering material, thus effectively killing, in a short time, microorganisms collected in the filtering material, such as bacteria, fungi, or viruses, which are harmful to the human body. Furthermore, a photocatalyst may be coated on the surface of the filtering material to achieve an improved sterilization effect. Thus, the deterioration of the sterilization effect caused by dust particles being continuously collected at the surface of filter fiber, which are disadvantages of existing antimicrobial filters, can be overcome.

  • Patent number: 8936671
    Abstract: An aircraft has a ventilation system that employs a plurality of nozzles positioned in a cavity between a sidewall of the aircraft cabin and a section of the aircraft fuselage. The nozzles receive a supply of ventilation air and direct jets of air from the nozzles, through the cavity and into the aircraft cabin. The jets of air produced by the nozzles create low-pressure areas in the cavity. At least one return air opening in the cabin sidewall communicates the low-pressure areas with the cabin interior, whereby the low pressure areas draw air from the cabin interior into the cavity where the drawn air is entrained with the jets of air produced by the nozzles. Devices inside the cavity remove suspended impurities from the air drawn into the cavity. In this manner, the ventilation system filters or sanitizes the air drawn through the system.

  • Patent number: 8703049
    Abstract: An apparatus and a method for purifying and heating air using photocatalytic oxidation. The apparatus includes a housing, a heater, and a photocatalytic oxidation unit disposed within the housing. The housing defines a flow path for air to move through the apparatus such that air from the environment is drawn into the apparatus and passes over the photocatalytic oxidation unit. A pollutant in the air from the environment adsorbs to a surface of the photocatalytic material coating the plates, and the surface of the photocatalytic material is exposed to ultraviolet light generated by the ultraviolet light source. The energy of the ultraviolet light activates the photocatalytic material, which then breaks down the pollutant leaving non-toxic components and purified air. The air then passes over the heater and back into the environment. A fan is also included to move air through the flow path.

    Abstract: Segmented stackable filter assembly for filtering a gas and method of manufacturing same. An exemplary embodiment of the segmented stackable filter assembly comprises a plurality of filter segments stackable end-to-end for varying filtration capacity of the stackable filter assembly. Each filter segment includes an annular outer wire mesh and an annular inner wire mesh spaced apart from the outer wire mesh to define a gap therebetween containing filter media. The inner wire mesh defines a central air flow passage axially through the filter assembly. A lower end plate has an opening for receiving a neck portion upwardly projecting from an adjacent upper end plate, so that both filter segments are prevented from laterally moving relative to each other. A fan assembly is supported by the neck portion for suctioning the gas through the plurality of filter segments.

  • Publication number: 20130333567
    Abstract: This disclosure describes embodiments of an air treatment apparatus that stimulates formation of large moisture droplets from small moisture droplets found in air flowing in power generating systems to a turbo-machine. In one example, the embodiments generate a field that promotes contact between the smaller moisture droplets. This contact can increase the size of moisture droplets to facilitate condensation of moisture out of the air.

  • Publication number: 20130291735
    Abstract: A device and method for air purification used in cooling, heating and air ventilation systems. The device has at least one UV light source positioned on an inside portion of a movable access panel so that it moves with the access panel from a first position where the UV source directs UV light towards the inside of the system to purify the air stream inside and to remove contaminants from the surfaces inside the system, to a second position where the UV source directs UV light towards the space surrounding the system so that it purifies the air in the room where the system is mounted.

  • Publication number: 20130239803
    Abstract: A method for reducing airborne contamination within a home includes installing an air-pressure control system within a window of the home, and drawing air from outside the home through the system inlet and an airflow path through the system. As it passes through the airflow path, a germicidal radiation chamber with a UV light source sterilizes the air. Additionally, filter(s) may clean the drawn air by removing particulates from the air as it passes through the filter. The method may then introduce the sterilized/cleaned air into the home through the system outlet. The sterilized/cleaned air may displace an equal volume of contaminated air within the home.

  • Patent number: 8535426
    Abstract: An apparatus, system, and method are disclosed for removing ethylene from a gaseous environment. Ethylene is a gaseous growth hormone produced by plants that triggers the ripening of some flowers, fruits, vegetables, and other plants. The apparatus includes an ethylene filter and a composition. The filter includes a frame and a trapping medium. The composition is attached to the trapping medium of the ethylene filter. The ethylene filter is positioned within a gaseous environment and is configured to encounter a gas flow within the gaseous environment. The composition contains at least some titanium dioxide which is configured to attach to the ethylene as the gas flow moves through and around the ethylene filter. In this manner, some ethylene may be removed from the gaseous environment.

  • Publication number: 20130236353
    Abstract: A device for disinfecting of gases and/or liquids, includes a tube of UV-transparent glass having a hollow interior space and a tube wall with a tube inside wall and a tube outside wall, as well as at least one UV-light source. The UV-transparent glass tube has an indentation extending into the interior space on at least one location and in the at least one indentation at least one UV-light source is arranged. The geometry causes the UV-light sources to be closer to the medium to be disinfected, so that a large portion of the UV-light reaches the interior space on a direct path through the glass, thus allowing for a low-loss transfer of the UV-light.
