Abstract: 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.

Abstract: The present invention provides an extension to a standard N-bit digital pulse width control method which can discriminate 2N discrete pulse widths per pulse cycle. The present invention provides a method and apparatus that can modulate the pulse widths over a period of 2M pulse cycles in which each pulse cycle can have its own pulse width or respective duty cycle. The resulting time averaged or effective pulse width therefore can be controlled with a resolution of 2N+M states rather than a resolution of 2N states as is common with standard methods.

Abstract: The present invention provides a drive and control apparatus provides a desired switched current to a load including a string of one or more electronic devices. A voltage conversion means, 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. A dimming control means provides control for activation and deactivation of the load and may further provide a means for current limiting. A feedback means is coupled to the voltage conversion means and a current sensing means and provides a control signal to the voltage conversion means that is indicative of voltage drop across the current sensing means which represents the current flowing through the load. Based on the control signal received, the voltage conversion means can subsequently adjust its output voltage such that a constant switched current is provided to the load.

Abstract: A system and method for controlling lighting are described. In general, the system and method may be used for controlling generation of light from the one or more lighting devices within a lighting system, in response to an external input. The control system generally comprises a control interface module and a light generation module. The control interface module is configured to receive the external input and convert same in accordance with a predefined internal control protocol. The light generation module is communicatively linked to the control interface module to receive the converted input and is operatively linked to the one or more light-emitting element modules for controlling generation of light thereby in accordance with the converted input. In one example, the light generation module is either interchangeable or interchangeably adaptable to receive the external input in accordance with one of two or more control protocols.

Abstract: The present invention provides a system and method for controlling one or more light-emitting elements which are driven by forward currents to generate mixed light for use, for example, through a luminaire. The system has one or more light sensors for acquiring feedback optical sensor data and a user interface for providing reference data representative of a desired mixed light. The system also has a controller for transforming either the sensor data or the reference data into the coordinate space of the other and to determine a difference between the sensor and the reference data in that coordinate space. The controller is configured to adjust the forward currents during operating conditions so that the sensor data matches the setpoint data. The present invention also provides a system and method that can at least partially compensate certain temperature induced effects when transforming the optical sensor or the reference data.

Abstract: 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. The luminaire system further comprises a controller that is operatively connected to the current driver system, the optical sensor system and the heat sensing system for receiving the signals generated by each of these systems and is configured to generate one or more drive signals for transmission to the current driver system in response to the optical signals and thermal signals received from the optical system and the heat sensing system, respectively, thereby enabling a desired level of control of the output light.

Abstract: The present invention provides a method and apparatus for digitally controlling a lighting device which enables a desired lighting device operational set point to be reached in a rapid manner while substantially reducing overshoot and oscillation about the desired lighting device operational set point. In particular the present invention is enabled by a PID controller configured to vary the PID controller parameters based on a relationship based at least in part on the desired lighting device operational set point, the present lighting device operational point or both.
