Abstract:
Examples of lighting equipment provide services to and on behalf of a biomechatronically enhanced organism and/or a biomechatronic component of the organism. Such services include charging, communications, location-related services, control, optimization, client-server functions and distributed processing functionality. The biomechatronically enhanced organism anchor biomechatronic component utilize such services provided by and/or via the lighting equipment to enable, enhance or otherwise influence operation of the organism.
Abstract:
Disclosed are examples of hyperspectral imager-equipped lighting devices that provide general illumination supplied by artificial or natural light, and that also detect environmental conditions in the environment around the lighting device. The hyperspectral imager detects light within a contiguous spectral band from the environment in the vicinity of the lighting device. In response, the hyperspectral imager generates image data representative of the spectral intensity of one or more subsets of a continuous spectrum of wavelengths of the detected light. A controller may analyze the image data generated by the hyperspectral imager and may initiate action to control operation of the light source or building management products based on an environmental condition detected by the analysis of the generated image data.
Abstract:
An example of a lighting system includes intelligent lighting devices, each of which includes a light source, a communication interface and a processor coupled to control the light source. In such a system, at least one of the lighting devices includes a user input sensor to detect user activity related to user inputs without requiring physical contact of the user; and at least one of the lighting devices includes an output component to provide information output to the user. One or more of the processors in the intelligent lighting devices are further configured to process user inputs detected by the user input sensor, control lighting and control output to a user via the output component so as to implement an interactive user interface for the system, for example, to facilitate user control of lighting operations of the system and/or to act as a user interface portal for other services.
Abstract:
The examples relate to various implementations to enable simultaneous controllable lighting distribution and a wide angle image light output from areas of a luminaire. An example of such a luminaire includes image light emitters and an array of general illumination light emitters for general illumination. A grid structure that has a supporting grid of rows and columns with intersection points and transparent sections or gaps is used to maintain a spaced arrangement of the general illumination light emitters and the image light emitters. Each of the transparent sections is bounded by individual structural members of the grid meeting at individual intersection points. In a specific example, image light emitters are located at intersection points of the grid structure. The general illumination light emitters are optically coupled for emitting general illumination light through the transparent sections of the grid.
Abstract:
A system for modulating passive optical lighting or natural light for visible light communication (VLC) in a non-enclosed space to obtain precise location information or broadband data transmission. The system includes an optical modulator having a framing structure that is at least substantially transmissive with respect to visible light and that has a modulating layer attached thereon.
Abstract:
Disclosed are examples of hyperspectral imager-equipped lighting devices that provide general illumination supplied by artificial or natural light, and that also detect environmental conditions in the environment around the lighting device. The hyperspectral imager detects light within a contiguous data from the environment in the vicinity of the lighting device. In response, the hyperspectral imager generates image data representative of the spectral intensity distribution (e.g. intensities of a continuous range wavelengths in the optical spectrum) of the detected light. A controller may analyze the image data generated by the hyperspectral imager and may initiate action based on, or outputs a report indicating, an environmental condition detected by the analysis of the generated image data.
Abstract:
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.
Abstract:
A lighting system utilizes intelligent system elements, such as lighting devices, user interfaces for lighting control or the like and possibly sensors. The system also has a data communication network. Some number of the intelligent lighting system elements, including at least two of the lighting devices, also support wireless communication with other non-lighting-system devices at the premises. Each such element has a communication interface system configured to provide a relatively short range, low power wireless data communication link for use by other non-lighting-system devices at the premises in proximity to the respective intelligent system element. Also, in such an element, the processor is configured to control communications via the communication interface system so as to provide access to the data network and through the data network to the wide area network outside the premises for non-lighting related communications of the other non-lighting-system devices.

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.
