Abstract: A master lighting fixture and a satellite lighting fixture can each include an LED board including multiple LEDs that can emit visible light. A power supply and a LED regulator can be connected to the LED board in the master lighting fixture to provide power to operate the LED board. The LED board in the master lighting fixture can be connected to the LED board in the satellite lighting fixture to form a circuit to allow the power provided by the LED driver to be transmitted to the LED board in the satellite lighting fixture. A defect in the LED board in the master lighting fixture or the satellite lighting fixture can open the circuit, which can prevent power from being transmitted through the LED boards to enhance the performance of LEDs in the LED boards or reduce a risk of damage that can be caused by the LED boards.

Abstract: An example luminaire includes a white light source (e.g. LEDs emitting white light in a region of the CIE color chart within three Macadam ellipses below the black body curve) and a violet light source emitting light in a wavelength range of approximately 380 nm to 450 nm (e.g. 405 nm LEDs) for deactivating bacteria, such as Methicillin-Resistant Staphylococcus aureus (MRSA) on a surface exposed to illumination from the luminaire. A controller coupled to the sources pulses the violet light source at an irregular rate and interval over a time period to apply a deactivation dosage of the violet light to bacteria within range of the emissions. When ON, the violet source emits light for deactivating bacteria at an intensity higher than the concurrent intensity of the white light.

Abstract: A luminaire includes a luminaire control circuit and a disinfection light source to emit a disinfection light in an ultraviolet (UV) band for disinfecting a vicinity of a physical space of a target pathogen that is exposed to the disinfection light. The UV band is 200 nanometers (nm) to 230 nm wavelength. The luminaire receives a control signal based on at least the mounting height of the luminaire. The luminaire adjusts a UV radiation threshold limit based on the control signal. The luminaire controls, via a driver circuit, the disinfection light source over a dose cycle to emit the disinfection light continuously or during the plurality of periods for disinfecting the vicinity to substantially obtain the target pathogen UV radiation level and restrict the total UV radiation threshold exposure level by the adjusted UV radiation threshold limit based on the control signal.

Abstract: A luminaire includes a luminaire control circuit and a disinfection light source to emit a disinfection light in an ultraviolet (UV) band for disinfecting a vicinity of a space of a target pathogen that is exposed to the disinfection light. The UV band is 200 nanometers (nm) to 230 nm wavelength. The luminaire initiates a dose cycle of a vicinity in which the disinfection light source emits the disinfection light continuously or during a plurality of periods of a dose cycle from the disinfection light source by recording a beginning time of the dose cycle. The luminaire controls, via a driver circuit, the disinfection light source over the dose cycle to emit the disinfection light continuously or during the plurality of periods for disinfecting the vicinity to substantially obtain a target pathogen UV radiation level and restrict a total UV radiation threshold exposure level by a UV radiation threshold limit.

Abstract: A cleansing lighting device includes a laser light source configured to emit light in the visible light spectrum or in the infrared light spectrum. The cleansing lighting device also includes a light frequency up-converter to convert longer wavelength light from the laser light source to shorter wavelength light. The converted light has a dominant wavelength in the portion of the ultraviolet range at or below 380 nm, suitable for the cleansing application. An example cleansing lighting device may also include an optical element, such as a beam shaping lens or a variable optical beam deflector, to distribute the resulting ultraviolet light from the up-converter for the cleansing application. Such a cleansing lighting device may be a standalone device, although the device or individual components for light-based cleansing may be incorporated in a luminaire, for example, together with an artificial light source adapted to general illumination.
