One or more such devices can work in a networked system, to support a variety of applications separate and in addition to the lighting related functions of the devices(s).
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 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.
Abstract:
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.
Abstract:
A system including a controllable device configured to provide a premises related service in an area of a premises. The system includes an electroencephalography (EEG) device configured to be positioned with respect to a head of a user and process signals detected in real-time. The system also includes a processor in communication with the EEG device, a memory accessible by the processor and instructions stored in the memory for execution by the processor. A data is stored in the memory that associates each of a plurality of predetermined sets of signals from the brain detected via the EEG device with at least one control instruction. The execution of the instructions configures the processor to using the stored data, analyze the real-time detected signals to determine that the real-time detected signals correspond to one of the plurality of predetermined set of signals associated with the one control instruction and generate a control data signal based on the one control instruction.

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.

A lighting device obtains data related to objects and boundaries in an area in the vicinity of the lighting device, and a user wearable device provides a display (e.g. an augmented reality display based on the data related to the objects and the area boundaries) for a user/wearer. The lighting device includes a mapping sensor that collects data related to the objects and boundaries in the area. The user wearable device includes a camera or other optical sensor and wireless communication capability. The user wearable device is provided with mapping data that is presented on a display of the user wearable device. The communications and display capabilities allow the user wearable device to obtain room mapping information related to area in the vicinity of the lighting device in order to provide navigational assistance to a visually impaired person in the area.
Abstract:
Disclosed are examples of lighting devices and other devices that are equipped with a cellular transceiver that is configured to communicate using licensed cellular radio frequency spectrum in both a small-scale cellular network and a large-scale cellular communication network. By utilizing a short-range, low-power cellular transceiver setting, a lighting device facilitates communication, within the space in which the lighting device is installed, of messages between the lighting device and other types of user devices. Such an equipped lighting device may be configured to participate in the generation and delivery of different types of messages, such as data, emergency broadcast information, news and other information as well extend the reach of devices within the space in which the equipped lighting devices are located.
Abstract:
A lighting device utilizes physical or virtual separation of elements within the lighting device to isolate a first portion of data for delivery to a first data network from a second portion of data for delivery to a second data network. The first portion of data relates to a first signal generated responsive to a first sensed condition. The second portion of data may relate to the first signal or to a second signal generated responsive to the first sensed condition or a second sensed condition. The lighting device utilizes a first communication interface to deliver the first portion of data to the first data network and a second communication interface to deliver the second portion of data to the second data network.
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.
