Abstract:
A lighting system utilizes intelligent lighting 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 optical wireless communication with non-lighting-system devices at the premises having optical transmitters and receivers. Each such element has a communication interface system configured to provide the optical wireless data communication link for use by other non-lighting-system devices at the premises via one of visible light spectrum; infrared light; or ultraviolet (UV) light. 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 non-lighting-system devices.
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:
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:
A system with a machine and a lighting device. The machine includes an image capture device and a machine vision processing system configured to detect a characteristic of a subject in a space for an operation of the machine. The lighting device includes a first light source for generating light to illuminate the space, and a second light source for generating light of a particular wavelength to support detection of the characteristic of the subject via the machine vision processing system. The light of the particular wavelength is output at a sufficient intensity reasonably expected to produce a particular emission from the subject detectable via the image capture device different from an emission produced by exposure of the subject to the light for illumination of the space. The first and second light sources are integrated into the lighting device.
Abstract:
Networked intelligent lighting devices and other elements connected to the network of a lighting system are readily adaptable to desirable networking arrangements as well as logical functional groups, for example by each storing communication provisioning data and/or configuration data for logically associating system elements into one or more groupings or sub-networks. The exemplary systems and system elements may also enable such enhanced network arrangement via autonomous discovery and device commissioning.

Abstract:
At least one controllable source of visible light is configured to illuminate a space to be utilized by one or more occupants. A controller causes the source(s) to emit light in a manner that varies at least one characteristic of visible light emitted into the space over a period of time at least in part in accordance with a chaotic function. Responsive to user input, sensed activity, and/or acquired information, the source(s) are controlled by the controller in accordance with a lighting control function which may be modified based on learning by a device or system including the controller.
