  • Patent number: 10433493
    Abstract: An approach for controlling ultraviolet intensity over a surface of a light sensitive object is described. Aspects involve using ultraviolet radiation with a wavelength range that includes ultraviolet-A and ultraviolet-B radiation to irradiate the surface. Light sensors measure light intensity at the surface, wherein each sensor measures light intensity in a wavelength range that corresponds to a wavelength range emitted from at least one of the sources. A controller controls the light intensity over the surface by adjusting the power of the sources as a function of the light intensity measurements. The controller uses the light intensity measurements to determine whether each source is illuminating the surface with an intensity that is within an acceptable variation with a predetermined intensity value targeted for the surface. The controller adjusts the power of the sources as a function of the variation to ensure an optimal distribution of light intensity over the surface.

The means for drawing air from the surrounding environment into the apparatus (120 and/or 220) mobilizes latent pathogens in the environment and draws them into the apparatus (100 and/or 200) for sterilization and disinfection. The air management chamber (130 and/or 230) provides for exposure of the airborne pathogens to UV radiation, via UV LEDs (150 and/or 250), with a dosage sufficient to penetrate the cell walls and destroy the pathogens. The electronics and control module (110 and/or 210) powers the apparatus (100 and/or 200) and interfaces with the electronic components. The housing (170) forms the outer shell of the apparatus (100).

  • Patent number: 9393339
    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: 9358313
    Abstract: An ultraviolet area sterilizer or disinfector is incorporated into a building structure where concern exists regarding the presence of pathogenic bacteria on environmental surfaces. Ultraviolet C (UV-C) generators generate UV-C that is directed to architectural partitions of an enclosed area. The architectural partitions reflect UV-C to kill pathogens in the enclosed area. The device transmits a calculated dose of UV-C from a fixture mounted to an architectural partition in the enclosed area. Once an effective cumulative dose of UV-C has been reflected to radiation sensors, as measured by the sensors, the device shuts down. The device may allocate power to specific UV-C emitters so as to direct UV-C radiation more uniformly throughout the area, as measured by the sensors.

  • Patent number: 9161999
    Abstract: Electron beam sterilization equipment includes an outer-surface sterilization zone Z2 for sterilizing the outer surface of a container B by emitting electron beams when the container B is transported along circular paths L1 and L2; and an inner-surface sterilization zone Z3 for sterilizing the inner surface of the container B. An electron beam irradiator E1 is located near the upstream side of a 1-2 joint J1-2 of the circular paths L1 and L2 disposed in the outer-surface sterilization zone Z2, and a electron beam irradiator E2 is located near the downstream side of the joint. Thus, the electron beam irradiator E1 and the electron beam irradiator E2 are brought close to each other so as to sequentially sterilize the one half outer surfaces and the other half outer surface of the container B.

  • Patent number: 9017613
    Abstract: In order to disinfect and to detoxify a fluid, a photoreactor contains at least two light sources. One light source activates the catalytic function of a semiconductor material in the fluid to reduce the concentration of contaminants in the fluid, such as by breaking down organic contaminants into non-toxic compounds. A second light source acts directly on living biological entities to sterilize or kill them and thereby disinfect the fluid, and can also serve to activate a semiconductor photocatalyst that in turn causes further damage to biological contaminants. The semiconductor photocatalyst is desirably attached to an optically transmitting fiber substrate in the fluid. The second light source in one embodiment is external to the fluid and illuminates the photocatalyst through transmitting surfaces in a fluid containment vessel. The light sources can comprise respective sets of plural LEDs.
