A wearable ultraviolet light phototherapy device is disclosed. The wearable ultraviolet light phototherapy device can have a substrate or a housing that is to be worn on a body part of a patient. At least one ultraviolet light emitting source located about the substrate or housing can deliver ultraviolet radiation into the body part of the patient. A control module can control operation of the at least one ultraviolet light emitting source. To this extent, the control module can direct the at least one ultraviolet light emitting source to deliver a predetermined amount of ultraviolet radiation at a peak wavelength into the body part of a patient. The control module can determine the predetermined amount of ultraviolet radiation as a function of the patient's susceptibility to ultraviolet radiation.

Wearable ultraviolet light phototherapy device

Ultraviolet irradiation of fluids for the purposes of disinfection, sterilization and modification of a target organic compound found within the fluids. The target compound in the fluids can have an absorption spectra with an ultraviolet wavelength ranging from 230 nm to 360 nm. The absorption spectra includes a first and second set of wavelengths corresponding to absorption peaks and absorption valleys in the absorption spectra, respectively. A-set of ultraviolet radiation sources irradiate the fluids. The set of ultraviolet radiation sources operate at a set of peak wavelengths ranging from 230 nm to 360 nm with a peak full width at half maximum that is less than 20 nm. The set of peak wavelengths are proximate to at least one wavelength in the second set of wavelengths corresponding to the absorption valleys in the absorption spectra with a variation of a full width half maximum of the absorption valley.

Ultraviolet irradiation of fluids

An approach for the treatment of surfaces in public places with ultraviolet light is disclosed. In one embodiment, a disinfection illuminator having ultraviolet radiation sources can irradiate a number of contact surfaces. A control unit can control the ultraviolet irradiation of the contact surfaces. The disinfection illuminator is suitable for a wide variety of devices that are used by the general public. Gas station pumps, door knobs, key pads, and bathrooms are illustrative of examples of some devices and places having commonly-used surfaces that can be treated by the disinfection illuminator.

Surface treatment with ultraviolet light

An approach for providing illumination with a blue UV light source, which can be used in combination with a visible light source is disclosed. In operation, the visible light source emits visible light at a first intensity. The blue UV light source emits blue UV light at a second intensity. The blue UV light stimulates fluorescence from a surface of an object illuminated by the blue UV light. A sensor can detect the intensity of the fluorescence from the surface illuminated by the blue UV light source. A control module can be operatively coupled to the visible light source, the blue UV light source, and the at least one sensor, and be configured to change the intensity of the visible light and/or the intensity of the blue UV light as a function of the fluorescent intensity detected by the sensor.
