In one aspect, an exterior lighting insect zapper includes a photosensor configured to sense an amount of light for turning on or off an exterior light and an insect zapper coupled to the photosensor. The exterior lighting insect zapper also includes a twist-lock plug compatible with a receptacle of an exterior light for a photosensor unit plug, such that the exterior lighting insect zapper can replace existing photosensors of exterior light fixtures.

A light fixture includes a visible light module and a germicidal light module. The visible light module may include one or more visible light engines designed for emitting visible light for general illumination. The visible light module may define a top side, a bottom side opposite the top side, and an outer perimeter around the top side and the bottom side. The visible light module may define an aperture extending through the visible light module from the top side to the bottom side. The visible light module may be designed to emit the visible light out of and across the bottom side from the outer perimeter to an inner perimeter defined by the aperture. The germicidal light module may be coupled to the visible light module. The germicidal light module includes a germicidal light engine designed to emit germicidal light through the aperture effective in deactivating pathogens.

A lighting fixture is disclosed with effective disinfection properties against bacteria, fungi, and viruses. The fixture includes a fan to continuously draw air into the light fixture. The air drawn in is irradiated with UV radiation within the fixture, such as is provided from UV LED chips. The relatively small volume of the light fixture allows the flux or energy density of the UV radiation to be made more intense. After the air is sterilized, it can be put back into the room or building in which the fixture is placed. The white light provided by white light LEDs in the fixture provides illumination, and can further provide significant emission peaks at 405 nm and 470 nm which is also useful to pathogen inactivation.

A portable illumination apparatus having a sterilizing function, the illumination apparatus including: a lamp unit which includes an illuminating light element on an interior side of the lamp unit; a base coupled to the lamp unit by a hinge; and a sterilizing light element located on the interior side of the lamp unit. When the lamp unit is in a closed position with the base, the lamp unit and the base meet at a boundary section to form a cylinder with a top and a bottom. Also, the boundary section is substantially mirror-symmetrical and at least partially U-shaped such that the lamp unit has a longest height line and a shortest height line. Additionally, the illuminating light element is arranged on or along the longest height line and the hinge is formed about the shortest height line.

A ceiling-mounted decontamination unit with one or more internal decontamination sources, which may be UV-C emitters, inside a housing with a hingable panel for access to the internal space of the housing for maintenance and repairs, and one or more fans inside the housing that re-circulate the air in a room and subject the air to the germicidal internal decontamination source inside the housing, decontaminating the air passing through the ceiling-mounted decontamination unit's internal space and destroying viruses, bacteria, and other pathogens. The ceiling-mounted decontamination unit draws the air in from the room or area where the ceiling-mounted unit is installed, subjects the air to the internal decontamination source destroying pathogens, and returns the decontaminated air back to the same room or area from which the air is drawn. An optional luminaire or external decontamination source may be attached to the room- or area-facing exterior of the ceiling-mounted decontamination unit.

The present invention relates to a flexible shield or guarding barrier device configured to protect a meal or work area from pathogens and accidental spills from beverage containers. The device is a lightweight and portable device that features an angular adjustable shield and a flat base. The flat base in positioned around the edge/rim of a plate or bowl having a meal or working area and the angular adjustable shield is pivotally-coupled to the flat base, thereby enabling a user to move the shield to protect the meal or work area. The shield in a closed state which makes a 10-20 degree angle with the base to maintain maximum coverage of the plate or work area when not in use.

An air filter health monitoring system includes a filter spanning an air passage for filtering solids and/or liquids out of an air flow passing through the air passage. An illuminator is positioned on a first side of the filter and directed to illuminate the filter. An illumination sensor is positioned on a second side of the filter. The illuminator and illumination sensor can each be spaced apart from the filter. The filter can be installed in a galley insert and can include a reticulated filter medium folded in a v-shape over a v-shaped grid work.

The present disclosure relates to a light and disinfection system, comprising: a lighting system which includes an illumination source and a diffusion hood suitable for the illumination source; a disinfection system which includes a disinfection light source and a cover adapted to transmit the disinfection light source, wherein the diffusion hood and the cover are respectively used for the illumination source and the disinfection light source.

A handheld flashlight includes a hollow cylinder having a first end and a second end, and a rechargeable battery therein. The handheld flashlight further includes a lamp head with a light source, a window breaker, a charging port and a discharging port, selectively connected to an external power source or an external load; a connection port, selectively connected to positive and negative terminals of a vehicle battery through external cables; and a management circuit, selectively applying power from the battery to one or more of the light source, the discharging port, and the connection, and selectively charging the battery from the external power source through the charging port; wherein the handheld flashlight is of such compact size and low weight as to be suitable for single-handed portable operation by a user.

A jump suicide prevention device includes a pair of link parts disposed to face each other in a longitudinal direction of the bridge railing, a roller part including rotation parts on opposite sides thereof in the longitudinal direction to be rotatably coupled between the link parts, leg parts respectively coupled to lower ends of the link parts by fastening members, and resilient members installed between end portions of the link part and the leg part with being interposed therebetween to control vertical movements of the link part. As a jump suicide prevention device capable of preventing a suicide jumper from jumping over the upper portion of the bridge railing, the device may prevent incidents of jump suicide from bridge railings due to the configuration of the roller part which rotates while vertically pivoting according to the weight of the suicide jumper.
