Abstract: A lighting system includes a lighting device configured to connect to an object. The lighting device includes a body and a control device. One or more ultraviolet light sources are attached to the body and connected to the control device. The ultraviolet light source(s) emit ultraviolet light in a wavelength range from 10 nm to 445 nm. The control device controls the frequency and duration of strobing of the ultraviolet light source(s). The control device cooperates with nearby emergency visible lighting and/or flashing visible light systems to designate and protect gaps in time from visible light illumination from the nearby emergency visible lighting and/or flashing visible light systems. The control device synchronizes the strobing of the ultraviolet light source(s) with the absence of visible light illumination from the nearby emergency visible lighting and/or flashing visible light systems during the designated gaps in time.

Abstract: A lighting system includes a lighting device arranged to attach to a vehicle. The lighting device includes at least two ultraviolet lights and at least one sensor. The sensor determines whether any of at least two areas or zones adjacent to the lighting device are poorly visibly illuminated and/or occupied by personnel, and illuminates these areas or zones with ultraviolet light. The lighting system is configured to operate in conjunction with existing emergency visible lighting and/or flashing visible light systems by using the sensors to sense visible illumination of each individual area or zone provided by the existing emergency visible lighting and flashing visible light systems. The lighting system may be configured to synchronize the illumination of each individual area or zone in ultraviolet light with intermittent absence of visible light illumination in each area or zone from the existing emergency visible lighting and flashing visible light systems.

Abstract: A lighting device is attached to a vehicle and includes a forward facing visible light source that emits visible light in a forward direction relative to the vehicle. The lighting device further includes a rearward facing ultraviolet light source that emits ultraviolet light in a rearward direction relative to the vehicle, such that a reflecting material of an object, which is not illuminated by the visible light source, is illuminated by the ultraviolet light source. A control device is connected to the light sources, and is configured to turn the light sources on and off. A light sensor is connected to the control device and is configured to sense ambient light and to provide a signal to the control device. The control device is configured to turn the ultraviolet light source on and off responsive to the signal of the light sensor.

Abstract: A lighting system including a lighting device configured to be connected to an object. The lighting device includes a body, at least one visible light source connected to the body, and at least one ultraviolet light source connected to the body. The at least one ultraviolet light source is operably coupled to the at least one visible light source. The lighting device is configured for strobing the visible light and ultraviolet light sources by turning the at least one ultraviolet light source on upon the at least one visible light source turning off and turning the at least one ultraviolet light source off upon the at least one visible light source turning on such that a reflectance material of an object, which is not being illuminated by the at least one visible light source, is illuminated by the at least one ultraviolet light source.
