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.

Claims

1. A system for controlling generation of light from one or more light-emitting elements in response to an external input, the system comprising:

a control interface module configured to receive the external input and convert same in accordance with a predefined internal control protocol; and

a light generation module communicatively linked to said control interface module and operatively linked to the one or more light-emitting elements for controlling same in accordance with said converted input.

2. The system as claimed in claim 1, wherein said control interface module is interchangeable or interchangeably adaptable to receive the external input when configured in accordance with any one of two or more external control protocols, and convert same in accordance with a same said predefined control protocol.

3. The system as claimed in claim 1, wherein the external input defines a preset in accordance with which the generation of light is to be controlled.

4. The system as claimed in claim 3, wherein said control interface module is configured to automatically detect a change in said external control protocol and implement a corresponding protocol conversion in response thereto.

5. The system as claimed in claim 1, the system comprising a control system for providing general illumination via the one or more light-emitting elements.

6. The system as claimed in claim 1, wherein said control interface module is configured to receive the external input via one or more of a DALI interface, a DMX interface, a manual interface and a proprietary protocol interface, and convert same in accordance with said predefined internal control protocol.

7. The system as claimed in claim 1, the system further comprising a feedback system configured to communicate one or more feedback signals representative of an operating condition of the system to said light generation module, said light generation module being further configured for adjusting generation of light from the one or more light-emitting elements in response to said one or more feedback signals.

8. The system as claimed in claim 7, wherein said one or more feedback signals comprise one or more optical feedback signals representative of an optical output of the one or more light-emitting elements.

9. The system as claimed in claim 7, wherein said one or more feedback signals comprise one or more thermal feedback signals representative of an operating temperature of the one or more light-emitting elements.

10. The system as claimed in claim 8, wherein said one or more feedback signals further comprises one or more thermal feedback signals representative of an operating temperature of an optical sensing element configured to provide said one or more optical feedback signals, said one or more thermal feedback signals thereby allowing for an adjustment of a response of said light generation module to said one or more optical feedback signals.

11. The system as claimed in claim 1, the system for controlling generation of light from one or more light-emitting elements of a plurality of lighting modules in a lighting system, each lighting module comprising a respective light generation module, the system further comprising a master control module configured to provide the external input to each said respective light generation module via one or more of a respective control interface module and a common control interface module.

12. The system as claimed in claim 1, the system further comprising an input/output module via which the external input is provided to said control interface module.

13. A method for controlling generation of light from one or more light-emitting elements in response to an external input, the method comprising the steps of:

receiving the external input;

converting the external input in accordance with a predefined internal control protocol; and

controlling generation of light from the one or more light-emitting elements in accordance with said converted input.

14. The method as claimed in claim 13, said receiving step comprising receiving the external input via any one of two or more external input interfaces, the method further comprising the step before said converting step of identifying from which of said two or more external input interfaces the external input is received, and converting same accordingly.

15. The method as claimed in claim 14, wherein said identifying step is implemented automatically via a computing module operatively coupled to said two or more external input interfaces.

16. The method as claimed in claim 15, wherein said identifying step comprises identifying an instance where the external input is not being received via a current one of said two or more external input interfaces, and automatically switching to another one of said two or more external input interfaces in response to said instance.

17. The method as claimed in claim 16, wherein said instance is defined by a predetermined time delay.

18. A lighting system comprising:

an external input module; and

one or more lighting modules each comprising one or more light-emitting element modules and a slave control unit operatively coupled thereto for driving said one or more light-emitting element modules;

each said slave control unit being communicatively linked to said external input module to receive an external input therefrom via a control interface;

said control interface configured to convert said external input in accordance with a predefined internal control protocol operable by said slave control unit to drive said one or more light-emitting element modules in accordance therewith.

19. The lighting system as claimed in claim 18, wherein the external input defines a common or respective preset in accordance with which said one or more light-emitting element modules of each of said one or more lighting modules are to be driven.

20. The lighting system as claimed in claim 18, wherein said external input module comprises a master control module.

21. The lighting system as claimed in claim 18, wherein said external input module comprises one or more of a remote I/O module and an integrated I/O module.

22. The lighting system as claimed in claim 18, wherein said external input module is selected from the group consisting of, a DMX controller, a DALI controller, a manual input interface and a proprietary controller.

23. The lighting system as claimed in claim 18, wherein each said slave control unit comprises a control interface module configured to provide said control interface, and a light generation module operatively coupled thereto for driving said one or more light-emitting element modules operatively coupled thereto in accordance with said converted external input.

24. The lighting system as claimed in claim 18, wherein said control interface is interchangeable or interchangeably adaptable to receive the external input when configured in accordance with any one of two or more external control protocols, and convert same in accordance with a same said predefined control protocol.

25. The lighting system as claimed in claim 18, wherein said slave control unit is configured to receive said external input when configured in accordance with in any one of two or more external control protocols, automatically detect which of said two or more external control protocols is being used, and convert said external input accordingly.
