Filed:

Aug 25, 2011

Appl. No.:

13/218148

Inventors:

Rashmi K. RAJ - Gainesville VA, US
Jason Rogers - Reston VA, US

International Classification:

H05B 37/02

US Classification:

315151, 315193

Abstract:

A system provides white light having a selectable spectral characteristic (e.g. a selectable color temperature and intensity) using a combination of sources (e.g. LEDs) emitting light of four, five, or six different characteristics, for example, one or more white LEDs, and one or more LEDs of each of three primary colors plus cyan and royal blue. A microcontroller can maintain a desired spectral characteristic, e.g. for white light at a selected point on or within a desired range of the black body curve. Further, the microcontroller provides tunability of the spectral characteristic and intensity of the white luminaire. One channel driver drives the one or more first color LEDs (white in our example) as well as the one or more second color LEDs which are connected in series to the first channel driver. The other light sources are each driven by separate drivers on separate channels.

Inventors:

Jason Rogers - Herndon VA, US
Rashmi K. Raj - Gainesville VA, US

International Classification:

H05B 37/02

US Classification:

315297

Abstract:

A lighting system having at least three light sources receives an input relating to color coordinates of a target point representing a desired color characteristic for a combined output from the light sources. The system defines first-pass endpoints corresponding to color characteristics of the light sources when operated at respective maximum intensities. The system determines first-pass amounts of respective maximum intensity contributions from the light sources to achieve light of the target point. When dimming the light to an intensity proportion, the system determines first-pass driver settings from the first-pass amounts and the intensity proportion. The system defines second-pass endpoints corresponding to color characteristics of the light sources when operated at the determined first-pass driver settings. The system determines, from the second-pass endpoints, second-pass amounts of respective reduced intensity contributions from the light sources; and the system determines second-pass driver settings for the second-pass amounts.

ABL IP HOLDING LLC - CONYERS GA

International Classification:

H05B 33/08

US Classification:

315151

Abstract:

A lighting system having at least three light sources receives an input relating to color coordinates of a target point representing a desired color characteristic for a combined output from the light sources. The system provides color tunable output and/or dimmable output in response to differences in user input. The system also corrects changes in performance of the light sources due to lifetime degradation in each of the light sources. After a period of system operation, outputs of the sources are measured. The system increases the luminosity outputs of each of the light sources by a respective amount relative to the degradations measured in all the light sources; in this manner, the luminosity outputs of the light sources remain substantially constant in relations to each other over the lifetime of the light sources.

International Classification:

H05B 33/08

US Classification:

315185 R, 315297

Abstract:

A system provides white light having a selectable spectral characteristic (e.g. a selectable color temperature, delta uv, and intensity) using a combination of sources (e.g. LEDs) emitting light of three, four, five, or six different characteristics, for example, one or more white LEDs, and one or more LEDs of each of three primary colors, plus cyan and royal blue. A controller maintains a desired spectral characteristic, e.g. for white light at a selected point on or within a desired range of the black body curve. In addition, the controller provides selectable adjustments for values of the spectral characteristics, while maintaining substantially constant overall output intensity for the light output of White LEDs, thereby achieving Maximum Utilization.

Appl. No.:

13/564519

Inventors:

David P. Ramer - Reston VA, US
Jason Rogers - Herndon VA, US

International Classification:

H05B 37/02

US Classification:

315294

Abstract:

A system of network-connected lighting devices also offers a distributed processing function that utilizes processor and/or memory resources if/when available in some or all of the lighting devices. In the examples, a resource manager receives a job for distributed processing using shared available resources. The resource manager identifies lighting devices having resources of the processors and/or the memories available for the distributed processing function. The resource manager distributes tasks and/or data of the received job through a communications network to identified lighting devices, for distributed processing. The resource manager also receives results of distributed processing for the received job, from the identified lighting devices through the communications network. The received results are processed to produce a composite result for a response to the received job.

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 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.
