Patent number: 11287315Abstract: A ultraviolet (UV) intensity indicator might use a UV responsive lumiphore to provide a converted, visible light level proportional to received UV light intensity for comparison to a visible brightness reference. For a desired UV intensity, the converted light should normally appear at least as bright as the reference light. For undesired UV, e.g. in a harmful wavelength range, the converted light should appear dimmer than the reference for normal operation and/or appear as bright as or brighter than the reference during excessive emission of the potentially hazardous UV emission. Alternatively, saturable lumiphores may provide different color outputs responsive to UV intensities for comparison to a multi-colored reference. Other examples contemplate use of a lumiphore to convert UV light to provide a visible light input to a visible light meter, such that an illuminance or brightness measurement by the meter gives a proportional representation of intensity of the UV light.Type: GrantFiled: April 14, 2020Date of Patent: March 29, 2022Assignee: ABL IP HOLDING LLCInventors: David P.

Patent number: 11119725Abstract: A control module, for lighting or other environmental control or the like has embedded voice responsive control capability. The recognizable command set supported by the control module is customizable. Software for a data processor configures the control module to identify a user in the vicinity of the control module and change voice response software based at least in part on identity of the user.

Patent number: 10866484Abstract: 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.Type: GrantFiled: September 4, 2018Date of Patent: December 15, 2020Assignee: ABL IP HOLDING LLCInventors: Guan-Bo Lin, David P.
