A face mask is connected via a tube to a housing containing an ultraviolet (UV) light-emitting diode (LED) in a channel. A power source is connected to the UV LED. The channel is helical in shape and has undulations, so as to maximize the amount time the air is subjected to the UV radiation. The housing rear face has a fins to allow the heat from the LEDs to dissipate through the fins during use. This arrangement protects the user and others from excessive UV exposure and heat during use.

A flameless electric candle having a fan-driven scent diffuser. The candle includes a body portion having a translucent portion and a generally elongated cylindrical shape and housing therein a light emitting device configured to permit its emitted light to be partially visually discernible through the translucent portion. There is below the body portion, a base portion that includes a PCB, a switch, a light emitting device, a power source, a fan oriented to force air in a downwards direction away from the body portion, a pad configured to receive upon a surface thereof a fragrance or scent, openings in a wall of the base portion to allow the forced air scented by the fragrance to escape the base portion. The switch is selectable among a first mode in which the LED and fan are both on, an off mode both the LED and fan are off, and a second mode wherein only one of the LED or fan is on.

A combination air filter and goggles includes a pair of goggles; an air filter; a tube having a first end attached to the goggles and a second end attached to the air filter; a first strap having two ends attached to the air filter; and a check valve disposed on the goggles. The air filter includes a centrifugal fan, a circuit board, a UV lamp, a filter element, a power supply, a housing, and a cover. Clean air produced by the air filter may flow to inside of the goggles.

A multifunctional light source assembly and a multifunctional desk lamp are disclosed. The multifunctional desk lamp includes a base assembly, a lamp head assembly, and a lamp arm assembly; one end of the lamp arm assembly is connected with the base assembly, and the other end is connected with and supports the lamp head assembly; the lamp head assembly is internally provided with the multifunctional light source assembly, the multifunctional light source assembly includes an illumination LED chip, a plant grow light LED chip and an ultraviolet LED chip. The illumination chip, the plant grow light chip and the ultraviolet chip are respectively connected to a controller, which respectively controls the three chips, through the on and off of currents, so that functions such as illumination for reading and writing, sterilization, plant growth assistance can be achieved.

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.

This application discloses an ultraviolet lamp tube comprising: an outer tube and an inner tube, each installed with an electrode, wherein the outer wall of the outer tube is coated with plated coatings A and B for filtering waves to enable emission of a single-wavelength light from the light source. This application also discloses an ultraviolet lamp tube comprising an inner tube and an outer tube each installed with an electrode, wherein the outer tube is coated with a plated coating A and a reflective coating to enable emission of a single-wavelengthe light with a high luminous efficiency. Through the method of plated coating, the UV lamps disclosed have achieved increased beam angle, improved light output power and luminous efficiency.

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.

In some examples, a device comprises a sanitizing member including a hollow tube having a reflective inner surface and first and second ends. The sanitizing member includes an ultraviolet (UV) light-emitting diode (UV-LED) at the first end. The second end has an orifice exposing the reflective inner surface to an environment of the device. The device also includes a facemask having an air valve coupled to the sanitizing member.

Disclosed is a scented candle warmer for overcoming trouble and inconvenience at once by easily processing and storing melted drippings and then simply discarding the drippings, and including a main body part including an accommodation groove for accommodating a collection container therein and a luminaire part formed on an upper part thereof, the collection container having a storage space for storing drippings of a scented candle and accommodated on or removed from the accommodation groove of the main body part, and a support part configured to detachably cover an upper part of the collection container and to simultaneously accommodate a scented candle container on an upper part thereof.

An example embodiment of an upper room air germicidal light fixture may comprise a light source configured to emit germicidal light and may further comprise one or more lower and upper baffle assemblies disposed adjacent to the light source. Said upper and lower baffle assemblies may be configured to enable air to flow through them and to block or substantially dissipate incident light rays from the light source. One or more apertures may be defined by the openings between a corresponding set of upper and lower baffle assemblies, wherein said light can exit the fixture through said apertures. When the germicidal light fixture is disposed in a room, surrounding room air may contact light exiting the apertures of said fixture, and room air traveling through said fixture may contact light inside and between the one or more upper and lower baffle assemblies.
