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: 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.

Abstract: Exemplary security lighting routines are tailored to disrupt visual perception and/or acuity so as to significantly reduce the ability of a person or persons, who has breached security, to function within a secured space. A routine triggered in response to a security breach includes a flash at a relatively high intensity, some number of times brighter than normal illumination for the space. Some exemplary routines include a warning light and/or a pre-flash light emission such as dim lighting or a flicker, to effectively prepare the person in the space for maximum effectiveness of the flash. Exemplary routines may also include a post-flash sequence of multiple color light emissions, such as alternating emissions in sequence of pulses of different colors of light using emission and/or off time parameters that vary in an irregular manner.

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: An example of a building automation system utilizes intelligent system elements, some of which are lighting devices having light sources, and some of which are utility building control and automation elements. Some utility building control and automation elements include a controllable mechanism for use in control of some aspect of the building other than lighting. Another intelligent system element may include either a user interface component and be configured as a building controller, or include a detector and be configured as a sensor. Each intelligent system element includes a network communication interface, processor, memory and programming to configure the intelligent system element as a lighting device, utility building control and automation element, controller or sensor. At least one of the intelligent lighting devices is configured as a building control and automation system server. Several examples, however, implement the overall control using distributed processing.

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.

The lamp may also include nanophosphors pumped by emissions of the LEDs, so that the lamp produces a white light output of particularly desirable characteristics.

Abstract: An optical/electrical transducer device has housing, formed of a thermally conductive section and an optically transmissive member. The section and member are connected together to form a seal for a vapor tight chamber. Pressure within the chamber configures a working fluid to absorb heat during operation of the device, to vaporize at a relatively hot location as it absorbs heat, to transfer heat to and condense at a relatively cold location, and to return as a liquid to the relatively hot location. The transducer device also includes a wicking structure mounted within the chamber to facilitate flow of condensed liquid of the working fluid from the cold location to the hot location. At least a portion of the wicking structure comprises semiconductor nanowires, configured as part of an optical/electrical transducer within the chamber for emitting light through and/or driven by light received via the transmissive member.

Abstract: A lamp for general lighting applications utilizes solid state light emitters and provides light output that may approximate light emissions from of an incandescent lamp. An exemplary lamp includes a bulb and a pedestal extending into the bulb that supports the light emitters in orientations such that emissions from the emitters through the bulb approximate emissions from a filament of an incandescent lamp. An inner member around the emitters and the pedestal provides further light processing, e.g. diffusing and/or phosphor luminescence. The lamp conforms to form factors and/or uses lamp base connectors of common incandescent lamps and/or compact fluorescent lamps. For efficient substitution of components during manufacture of lamps to different specifications, at least some examples use modular couplings for the parts of the lamp to the heat sink or other housing, such as for couplings of the lamp base, the bulb and the inner light processing member (if provided).

Abstract: A thermal conductivity and phase transition heat transfer mechanism incorporates an active optical element. Examples of active optical elements include various phosphor materials for emitting light, various electrically driven light emitters and various devices that generate electrical current or an electrical signal in response to light. The thermal conductivity and phase transition between evaporation and condensation, of the thermal conductivity and phase transition heat transfer mechanism, cools the active optical element during operation. At least a portion of the active optical element is exposed to a working fluid within a vapor tight chamber of the heat transfer mechanism. The heat transfer mechanism includes a member that is at least partially optically transmissive to allow passage of light to or from the active optical element and to seal the chamber of the heat transfer mechanism with respect to vapor contained within the chamber.
