Publication number: 20090026978Abstract: A light source is configured to send a beacon signal representative of the unique identifier thereof, on command, constantly or at a predetermined interval. The beacon signal is integrated into the light emitted by the light source, wherein the integration of the beacon signal is performed in a manner that visible flicker of the resultant light is imperceptible. A remote detection unit is configured to receive the light and extract the beacon signal therefrom. In this manner the remote detection device is capable of wirelessly determining the unique identifier of a light source. The collected unique identifier of the light source can subsequently be provided to a controller associated with the light source, thereby providing individual control of the light source by the controller. Through the use of electronic data transfer from the remote detection unit to the controller, the provision of the one or more unique identifiers to the controller can be enabled in an efficient and accurate manner.Type: ApplicationFiled: February 22, 2007Publication date: January 29, 2009Applicant: TIR TECHNOLOGY LPInventor: Shane Robinson

Patent number: 7423387Abstract: The present invention provides a method and apparatus for controlling the correlated colour temperature (CCT) or colour of light produced by an array of light-emitting elements by providing multiple selectable paths for the flow of drive current. The apparatus includes a primary path comprising primary light-emitting elements, and one or more secondary paths comprising secondary light-emitting elements that are used for compensation or correction of the colour of light emitted by the primary light-emitting elements. A plurality of control means, for example switches are used to direct current through particular paths. During operation, the drive current primarily flows through the primary light-emitting elements and is redirected, periodically for example, to a secondary path comprising light-emitting elements of a particular colour that is desired in addition to the colour produced by the primary light-emitting elements.Type: GrantFiled: November 23, 2005Date of Patent: September 9, 2008Assignee: TIR Technology LPInventors: Shane Robinson, Paul Jungwirth

Publication number: 20070273290Abstract: The present invention provides an integrated self-contained lighting module which can be used on its own, or in conjunction with other modules to produce white light, or light of any other colour within the colour spectrum. Each module comprises one or more light-emitting elements, a drive and control system, a feedback system, thermal management system, optical system, and optionally a communication system enabling communication between modules and/or other control systems. Depending on the configuration, the lighting module can operate autonomously or its functionality can be determined based on either or both internal signals and externally received signals.Type: ApplicationFiled: November 29, 2005Publication date: November 29, 2007Inventors: Ian Ashdown, Paul Jungwirth, Shane Robinson, Philippe Schick, Ingo Speier, Allan York

Publication number: 20070085489Abstract: The driving and control device according to the present invention provides a desired switched current to a load including a string of one or more electronic devices, and comprises one or more voltage conversion means, one or more dimming control means, one or more feedback means and one or more sensing means. The voltage conversion means may be a DC-to-DC converter for example and based on an input control signal converts the magnitude of the voltage from the power supply to another magnitude that is desired at the high side of the load. The dimming control means may comprise a switch such as a FET, BJT, relay, or any other type of switching device, for example, and provides control for activation and deactivation of the load. The feedback means is coupled to the voltage conversion means and a current sensing means and provides a feedback signal to the voltage conversion means that is indicative of the voltage drop across the current sensing means which thus represents the current flowing through the load.Type: ApplicationFiled: December 20, 2006Publication date: April 19, 2007Applicant: TIR Systems Ltd.Inventors: Shane Robinson, Paul Jungwirth, Ion Toma

Publication number: 20070040512Abstract: The present invention provides a luminaire system capable of generating light of a desired chromaticity and luminous flux output during continuous operation with varying ambient operating temperature. The luminaire system can be further capable of maintaining a desired correlated colour temperature during dimming of the luminaire. The luminaire system comprises one or more arrays of light-emitting elements for generating light with a current driver system coupled thereto for selectively supplying electrical drive current to each of the arrays, wherein the current driver system is responsive to drive signals received from a controller. The luminaire system further comprises an optical sensor system for generating optical signals representative of chromaticity and luminous flux output of the light. A heat sensing system is operatively coupled to the one or more arrays for generating signals representative of the junction temperatures of arrays of light-emitting elements during operation.Type: ApplicationFiled: December 21, 2005Publication date: February 22, 2007Applicant: TIR Systems Ltd.Inventors: Paul Jungwirth, Shane Robinson, Ingo Speier

Publication number: 20060245174Abstract: The present invention comprises a method and system for controlling the chromaticity and luminous flux output of a digitally controlled luminaire. The luminaire comprises one or more light-emitting elements and one or more light sensors which can provide optical feedback, wherein this optical feedback is filtered to remove undesired frequencies. The method and system comprises a control system which can sample the filtered signals from the light sensors according to a predetermined feedback sampling frequency scheme, wherein this scheme is specifically configured to provide sufficient iterations of the feedback loop to be performed for adjustment of the chromaticity and luminous flux output of the light-emitting elements, without perceptible visual flicker or momentary chromaticity shifts.Type: ApplicationFiled: June 26, 2006Publication date: November 2, 2006Applicant: TIR SYSTEMS LTD.Inventors: IAN ASHDOWN, SHANE ROBINSON

Publication number: 20060226336Abstract: The present invention provides a method and apparatus for collecting and detecting light emitted from a plurality of light-emitting elements. The light-emitting elements are grouped into two or more clusters of one or more light-emitting elements with the clusters arranged such that a portion of the light emitted from each cluster is directly incident upon a central axis, wherein every point along the central axis is equidistant from each cluster. A light collection means also having a central axis associated therewith is placed such that the central axis of the clusters and the central axis of the collection means coincide. The light collection means collects a substantially equal portion of light from each cluster and propagates the collected light to a detection means comprising an optical sensor for conversion to an electrical signal representative of the light emitted by the clusters.Type: ApplicationFiled: March 23, 2006Publication date: October 12, 2006Applicant: TIR Systems Ltd.Inventors: Allan York, Shane Robinson, Ian Ashdown, Ingo Speier
