Provided is an air cleaner, and more specifically, to an air cleaner in which a filter part using a photocatalyst is formed in a module type to facilitate replacement and cleaning and which includes an insert fan which is disposed inward from a suction port of a casing forming an exterior and including the suction port disposed at one side and a discharge port disposed at the other side, and suctions ambient air, a driving motor provided to be axially detachably coupled to the insert fan in a direction from the discharge port, and a suction unit fixing part in which an accommodation space, into which the insert fan and the driving motor are fixedly inserted in the direction from the suction port toward the discharge port and which is finished by inserting a cover member in the direction from the discharge port.

A device for disinfecting surfaces is provided. One embodiment has a plurality of UV light (energy) emitting LEDs residing in an enclosure, wherein emitted UV energy passes through a lens onto a surface being disinfected; a heat dissipator that receives heat generated by the UV emitting LEDs; and a fluid moving device. The enclosure has a fluid heating passageway that is in fluid contact with the heat dissipator, has a transfer passageway with a distal end that is fluidly coupled to a proximal end of the fluid heating passageway, and has a return passageway that is fluidly coupled to a proximal end of the transfer passageway and that is fluidly coupled to a distal end of the fluid heating passageway. During operation, the fluid moving device operates to circulate a cooling fluid through the fluid heating passageway, the transfer passageway, and the return passageway. Heat transfers to the ambient environment.

A portable airborne pathogen control apparatus and system. Aspects of the present disclosure provide for a portable airborne pathogen control apparatus configured to be selectively positioned within an interior room and configured to enable a floor-to-ceiling flow of air within the interior room. The portable airborne pathogen control apparatus may comprise a housing with an air intake disposed at a lower area of a base housing and an air outlet disposed at an upper area of an elongated duct extending from the base housing. A blower fan housed within an interior chamber of the housing may be configured to direct a floor-to-ceiling flow of air through the interior chamber from the air intake to the air outlet. A volume of air directed through the interior chamber of the housing may be disinfected using one or more UV-C emitters and/or cold plasma generator(s) housing in the interior chamber of the housing.

A hybrid LED lighting device, in particular a recessed spotlight, with lighting and sanitizing functions, comprises: a support structure extending along a longitudinal axis; a central LED source, positioned along the axis and emitting white light; and a plurality of UV-C LED sources, emitting in the UV-C band and arranged spaced apart from one another about the axis and about the central LED source to form an LED ring.

A modular disinfection vehicle. The disinfection component is designed into an independent extensible structure, where there is a light source module between the upper end and the lower end of the disinfection component, the upper end of the disinfection component is the first fixing part, the lower end of the disinfection component is the second fixing part, the upper end of the disinfection component is of a dismountable structure, so that the light source module can be replaced and maintained conveniently; when the quantity of the light source modules needs to be increased or decreased, only components and parts at the upper end or/and the lower end of the disinfection component need to be replaced, there is no need to significantly improve the overall structure of the disinfection vehicle, so that the quantity of light source modules of the disinfection vehicle can be increased or decreased conveniently.

Described is a scent producing assembly having a self-contained module comprising an absorptive matrix infused with a volatile composition and a housing. The housing may include a receptacle shaped to receive the module, wherein the housing has a stowed position and a deployed position. In the stowed position, the receptacle may be contained within an interior of the housing. In the deployed position, the receptacle may be displaced out of the housing. The receptacle may move along an arcuate path when the receptacle is moved between the stowed and deployed positions.

A device for diffusing volatile substances includes a container containing a liquid with the volatile substances, a base element that closes the container, and a wick that is impregnated with the volatile substances. The base element includes an internal channel in which the liquid containing the volatile substances is deposited. A part of the wick placed in the internal channel is impregnated with the liquid containing the volatile substances located in the internal channel.

An irradiation method includes irradiating an environment with light using one or more one ceiling-mounted light sources, where each ceiling-mounted light source has an optical axis oriented vertically downward, and wherein each ceiling-mounted light source emits a light distribution having more angle-integrated intensity in a higher angular range relative to the optical axis of the ceiling-mounted light source than in a lower angular range relative to the optical axis of the ceiling-mounted light source. A ceiling-mounted light source may include a support structure, one or more light emitters disposed on a surface of the support structure, and a reflector with a funnel-shaped reflective surface facing the support structure and expanding with increasing distance from the support structure along the optical axis. The light emitters may be ultraviolet (UV) light emitters whereby the light source is a UV ceiling-mounted light source.
