An air filtration media with integrated disinfection capability. The media has a collection filter for capture of pathogens, and an ultraviolet (UV) radiation source integrated into the collection filter such that the pathogens collected by the collection filter are exposed to UV radiation from the UV radiation source.

Multi-layer air filtration media with integrated disinfection capability

A mannikin-based optical analyzer for analyzing an exposure of a subject to an environmental lighting condition. The analyzer has a mannikin with an outer surface replicating a facial profile of the subject, an interior inside the outer surface, and at least one pupil for admission of light into the interior of the mannikin. The analyzer has at least one optical detector configured to acquire and wavelength analyze light directed through the at least one pupil.

Advanced lighting effects investigation system and computerized method

A fiber-based reflective lighting device and a housed lighting device. The fiber-based reflective lighting device which includes a source configured to generate a primary light, and a substrate having a nanocomposite mat of reflective fibers having a diameter less than 1,000 nm which diffusively reflects light upon illumination with at least the primary light. The nanocomposite mat includes a reflectance-enhancing coating conformally disposed around an outer surface of the fibers, having a refractive index different from the reflective fibers, and which increases a reflectance of the substrate in the visible spectrum. The lighting device includes a light exit configured to emanate the reflected light. The housed lighting device includes a housing, a source configured to generate primary light and direct the primary light into the housing, the reflective nanocomposite mat of reflective fibers, and a light exit in the housing configured to emanate the reflected light from the housing.

Reflective nanofiber lighting devices

A photoluminescent nanofiber composite includes a nanofiber substrate, first luminescent particles, and second luminescent particles. The first luminescent particles are supported by the nanofibers and span at least a portion of a substrate surface, as a layer on the substrate surface, or with some particles located in a bulk of the substrate, or both. The second luminescent particles are disposed on the substrate. The second luminescent particles may be disposed directly on the substrate surface or on the first luminescent particles. The second luminescent particles may be deposited in a pattern of deposition units. The first and second luminescent particles are configured for emitting light of different respective wavelengths in response to excitation by a light beam. One or more surface treatment coatings may be provided at different locations.

A fiber-based reflective lighting device and a lighting device. The fiber-based reflective lighting device includes a source configured to generate a primary light, a mat of reflective fibers which diffusely reflects light upon illumination with at least the primary light, and a light exit configured to emanate the reflected light. The lighting device includes a housing, a source configured to generate primary light and direct the primary light into the housing, a reflective mat of fibers disposed inside the housing at a position to reflect the primary light, and a light exit in the housing configured to emanate the reflected light from the housing.

A fiber-based reflective lighting device. The lighting device includes a source configured to generate a primary light, a substrate including a mat of reflective nanofibers, and a light exit configured to emanate the reflected light. The fibers have an average fiber diameter AFD less than 500 nm which diffusively reflects visible light upon illumination with at least the primary light. The mat has a basis weight less than 40 gram per square meter (gsm) and a reflectance greater than 80%.
