Abstract: An LED device capable of emitting electromagnetic radiation ranging from about 200 nm to 365 nm, the device. The device includes a substrate member, the substrate member being selected from sapphire, silicon, quartz, gallium nitride, gallium aluminum nitride, or others. The device has an active region overlying the substrate region, the active region comprising a light emitting spatial region comprising a p-n junction and characterized by a current crowding feature of electrical current provided in the active region. The light emitting spatial region is characterized by about 1 to 10 microns. The device includes an optical structure spatially disposed separate and apart the light emitting spatial region and is configured to facilitate light extraction from the active region.

Abstract: A variety of applications for UV LEDs that are integrated into a system are described, where the UV light is used for disinfection of air or surfaces, or used to detect the scattering light by particles, or used for skin treatment. In one embodiment, the UV light from the UV LEDs is generated internal to a housing and is optically coupled to a transparent or translucent surface touched by the human finger, such as a touch screen, a fingerprint scanner, backlit buttons or keys, a toggle of a light switch, a door knob, etc. The UV light is emitted through the touched surface to periodically disinfect the surface. A visual indication of the UV LEDs being energized is provided for safety, such as energizing visible light LEDs or a phosphor on a portion of the touched surface.
