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.

Abstract: The application discloses a method and apparatus for providing a desired warning signal for a lighting unit. A coded warning system is provided employing a detection module (320) and a signal generating module (330), wherein the detection module is configured to obtain information regarding the detection of one or more operating parameters of the lighting unit and the signal generating module generates a desired warning signal (331) selected from a plurality of warning signals, upon determination that one or more of the operating parameters are abnormal operating parameters. Each warning signal of the plurality of warning signals is indicative of a specific abnormal operating parameter or a known combination of specific abnormal operating parameters.

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.
