Patent number: 10935215Abstract: An example lighting device includes a luminaire having an illumination light source including an illumination light source configured to be driven by electrical power to emit incoming light rays. Luminaire further includes a polarization selective optic coupled to the illumination light source to receive the incoming light rays emitted by the illumination light source and output polarized light rays for illumination lighting. Based on the incoming light rays, the polarization selective optic outputs the polarized light rays including a TM wave. Polarization selective optic steers the TM wave to be outputted to a far field at a grazing angle. Polarization selective optic steers a substantially non-TM wave away from the far field at the grazing angle. Lighting device further includes an illumination light source driver to control a light source operation of the illumination light source.Type: GrantFiled: September 26, 2019Date of Patent: March 2, 2021Assignee: ABL IP HOLDING LLCInventors: Guan-Bo Lin, David P.

Patent number: 10928623Abstract: Disclosed are examples of optical/electrical devices including a variable TIR lens assembly having a transducer, an optical lens and an electrowetting cell coupled to an exterior wall of the lens. The electrowetting cell contains two immiscible liquids having different optical and electrical properties. One liquid has a high index of refraction, and the other liquid has a low index of refraction. At least one liquid is electrically conductive. A signal causes the high index of refraction and the low index of refraction liquids to assume various positions within the electrowetting cell along the exterior wall. The properties of the optical lens, e.g. its total internal reflectivity, change depending upon the position of the respective liquids along the exterior wall. The light detection characteristics of the assembly change to receive an input light beam over a range of inputs or over a range of fields of view.Type: GrantFiled: May 9, 2018Date of Patent: February 23, 2021Assignee: ABL IP HOLDING LLCInventors: David P.

Patent number: 10873175Abstract: To improve efficiency, particularly for general illumination applications, a source of green or yellow light includes a solid state device (e.g. a laser diode) to produce an infrared laser beam and a light frequency up-converter to convert the infrared light into green or yellow light. A luminaire includes such a source as well as a source providing two other colors of light, such as red and blue (e.g. not green or yellow). The emitters of the other source may be light emitting diodes or additional laser diodes. The luminaire outputs a combination of the various colors of lights from the sources, for example, to produce white light. If the different emitters are independently controllable, the luminaire may be adjusted or ‘tuned’ to output white light of different color characteristics and/or to output combined light of various colors over a wide region of the visible light color gamut.Type: GrantFiled: January 28, 2019Date of Patent: December 22, 2020Assignee: ABL IP HOLDING LLCInventors: David P.

Patent number: 10866638Abstract: A system includes a controllable device configured to provide a premises related service in an area. The system includes a neural device to be positioned with respect to a part of a body of a user and circuitry to process nerve signals detected in real-time. The system also includes a processor in communication with the circuitry, a memory and instructions stored in the memory for execution by the processor. Data stored in the memory associates each of some number of predetermined sets of nerve signals with a control instruction. Execution of the instructions configures the processor to use the stored data to analyze the real-time detected nerve signals to determine when real-time detected nerve signals correspond to one of the predetermined sets of nerve signals and generate a control data signal based on the associated control instruction to cause a controller to control an operation of the controllable device.Type: GrantFiled: December 12, 2018Date of Patent: December 15, 2020Assignee: ABL IP HOLDING LLCInventor: David P.

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.

Publication number: 20200296815Abstract: An exemplary lighting system utilizes intelligent system elements, such as lighting devices, user interfaces for lighting control or the like and possibly sensors, and utilizes network communication amongst such intelligent system elements. Some processing functions performed within the system are implemented on a distributed processing basis, by two or more of the intelligent elements of the lighting system. Distributed processing, for example, may enable use of available processor and/or memory resources of a number of intelligent system elements to process a particular job. Another distributed processing approach might entail programming to configure two or more of the intelligent system elements to implement multiple instances of a server functionality with respect to client functionalities implemented on intelligent system elements.Type: ApplicationFiled: May 28, 2020Publication date: September 17, 2020Inventors: Januk AGGARWAL, Jason ROGERS, David P.

Patent number: 10753792Abstract: A spectrometer-equipped lighting device detects substances in an environment around the device. A fiber detector is optically coupled to receive light from a light source. The fiber detector has a bare area from which emanates an evanescent wave of light surrounding an exterior of the fiber detector to interact with the environment in which the fiber detector is exposed. The spectrometer, optically coupled to an opposite end of the fiber detector, detects the light output and in response, generates signals representative of the spectral power distribution of the light of the evanescent wave that has interacted with the surrounding environment. A controller analyzes the spectrometer generated signals and initiates action based on the analysis of the generated signals or outputs a report indicating an environmental condition detected by the spectrometer-equipped device.Type: GrantFiled: September 17, 2019Date of Patent: August 25, 2020Assignee: ABL IP HOLDING LLCInventors: David P.

Publication number: 20200200359Abstract: A tunable luminaire includes a laser light source and at least two different holograms. A beam of light is selectively directed from the laser light source to a first hologram in a first state of the luminaire to enable the luminaire to output light of a first characteristic. A beam of light is selectively directed from the laser light source to a second hologram in a second state of the luminaire to enable the luminaire to output light of a different second characteristic. For example, in the different states, different patterns of light from the holograms pass through and pump different photoluminescent materials, to produce luminaire light outputs in the different states having a different color characteristic. In other examples, in the different states, different patterns of light from the holograms pass through different elements or portions of an optical system to provide light outputs having different distributions.Type: ApplicationFiled: December 20, 2018Publication date: June 25, 2020Inventors: Guan-Bo LIN, David P.
