In one example embodiment, a lighting system includes can include one or more high intensity narrow spectrum light sources configured to emit high intensity narrow spectrum light. The lighting system can further include a power circuit configured to provide power to the one or more high intensity narrow spectrum light sources and a pulsing circuit configured to control delivery of power to the one or more high intensity narrow spectrum light sources so as to pulse the emission of high intensity narrow spectrum light from the one or more high intensity narrow spectrum light sources.

A single-use towel dispenser, sterilizer and usage logging device with a refillable storage compartment for storing a single-use towel supply including an access door for refilling the single-use towel supply and a dispensing port, an ultra-violet sterilization element, a single-use towel dispensing mechanism, a user input device, a non-transitory memory storing an executable code and a hardware processor executing the executable code to receive a user input via the user input device, activate, in response to the user input, the ultra-violet sterilization element, dispense, using the single-use towel dispensing mechanism, a sterilized single-use towel by passing a first length of single-use towel from the single-use towel supply within an effective distance of the activated ultra-violet sterilization element such that the first length of single-use towel is illuminated by an ultra-violet light having sufficient intensity to sterilize the first length of single-use towel and store sterilization and usage data in the non-transitory memory.

Given the complexity of architectural spaces and the need to calculate spherical irradiances, it is difficult to determine how much ultraviolet radiation is necessary to adequately kill airborne pathogens. An interior environment with luminaires is modeled. Spherical irradiance meters are positioned in the model and the direct and indirect spherical irradiance is calculated for each sensor. From this, an irradiance field is interpolated for a volume of interest, and using known fluence response values for killing pathogens, a reduction in the pathogens is predicted. Based on the predicted reduction, spaces are built accordingly, and ultraviolet luminaires are installed and controlled.

In a system and method for disinfecting a surface of an object with iodine-laden gas, a carrier gas generation means generates a gas stream, which is then directed into a chamber that includes an iodine source. As the gas stream enters and passes through the chamber, iodine is drawn and absorbed into the gas stream, creating an iodine-laden gas that exits the chamber. The carrier gas stream is humidified prior to or after its interaction with the iodine source. In some embodiments, the iodine-laden gas then travels from the chamber and is directed into an enclosure when it interacts with microbes contained on a surface of an object housed within the enclosure or otherwise engaged by the enclosure. In other embodiments, as the iodine-laden gas exits the chamber, it is directed to a nozzle, via which the iodine-laden gas is applied to the surface of the object to be disinfected.

According to an aspect, a display device includes: a display panel including a display surface; a sensor configured to detect an external object in proximity to or in contact with the display surface; an ultraviolet light emitter configured to emit ultraviolet light to the display surface; and a controller configured to control an operation of the ultraviolet light emitter. The controller increases an emission amount of ultraviolet light from the ultraviolet light emitter as the object approaches the display surface, and reduces the emission amount of ultraviolet light from the ultraviolet light emitter as the object recedes from the display surface.
