Abstract

A solid state lighting switch can include a first input control that can be configured to adjust a dimming indication or color indication for a solid state lighting fixture that is configured for coupling to the solid state lighting switch. A selective linking mechanism can be configured to activate a linked mode of operation of the switch to link the dimming indication to the color indication or to activate an unlinked mode of operation of the switch to unlink the dimming indication from the color indication.

Claims

1. A method of operating a switch comprising:

providing a dimming indication and a color indication configured for coupling to a solid state lighting device responsive to a first input control of the switch;

selectively linking the color indication to the dimming indication responsive to activation of a linked mode of operation for the switch; and

transmitting the color indication and the dimming indication from the switch.

2. The method of claim 1 further comprising:

selectively unlinking the color indication from the dimming indication responsive to activation of an unlinked mode of operation for the switch.

3. The method of claim 1 further comprising:

providing the color indication responsive to a second input control to the switch.

4. The method of claim 3 wherein selectively linking the color indication to the dimming indication comprises selectively linking outputs of the switch to one another to couple the color indication to the dimming indication.

5. The method of claim 2 wherein selectively unlinking comprises coupling the dimming indication to a first output of the switch and coupling the color indication to a second output of the switch in the unlinked mode of operation to provide independent outputs from the switch.

6. The method of claim 4 wherein a relationship of the color indication to the dimming indication provides incandescent style dimming.

7. The method of claim 1 wherein the color indication is proportional to the dimming indication to provide limited incandescent style dimming at the solid state lighting device.

8. The method of claim 1 wherein the switch comprises a wireless interface configured to transmit the color indication and the dimming indication wirelessly to the solid state lighting device.

9. The method of claim 1 wherein the color indication comprises a correlated color temperature.

10. The method of claim 1 wherein the color indication comprises a color registered index.

11. The method of claim 1 wherein transmitting the color indication and the dimming indication from the switch comprises wirelessly transmitting the color indication and the dimming indication from the switch.

12. A solid state lighting switch configured for providing a color indication and a dimming indication to a solid state lighting fixture, the solid state lighting switch comprising:

an input control; and

a selective linking mechanism configured to control whether the switch operates in a linked mode or in an unlinked mode, wherein in the unlinked mode the dimming indication and the color indication are unlinked such that manipulation of the input control causes change to only the dimming indication or only the color indication and wherein in the linked mode the dimming indication and the color indication are linked such that manipulation of the input control causes change to both the dimming indication and the color indication.

13. The solid state lighting switch of claim 12, wherein in the linked mode the dimming indication and the color indication are linked such that manipulation of the input control causes the color indication to vary as a function of the dimming indication.

14. The solid state lighting switch of claim 12, wherein in the linked mode the dimming indication and the color indication are linked such that manipulation of the input control causes the color indication and the dimming indication to vary in unison with one another.

15. The solid state lighting switch of claim 12, wherein the input control is a first input control configured to control only the color indication when the switch operates in the unlinked mode, wherein the switch further comprises a second input control configured to control only the dimming indication when the switch operates in the unlinked mode, and wherein in the linked mode the dimming indication and the color indication are linked such that manipulation of the first input control causes change to both the dimming indication and the color indication.

16. The solid state lighting switch of claim 12, wherein the input control is the only input control of the switch for controlling the dimming indication and the color indication.

17. The solid state lighting switch of claim 12, wherein in the unlinked mode the dimming indication and the color indication are unlinked such that manipulation of the input control from a first position to a second position causes change to only the dimming indication or only the color indication, and wherein in the linked mode the dimming indication and the color indication are linked such that manipulation of the input control from the first position to the second position causes change to both the dimming indication and the color indication.

18. The solid state lighting switch of claim 12, wherein the selective linking mechanism is electrical such that the color indication is electrically coupled to the dimming indication in the linked mode.

19. The solid state lighting switch of claim 12, wherein the selective linking mechanism is configured to control whether the switch operates in the linked mode or in the unlinked mode in response to a user selection between the linked mode and the unlinked mode.

20. The solid state lighting switch of claim 12, wherein the selective linking mechanism is configured to control whether the switch operates in the linked mode or in the unlinked mode in accordance with a user-specified schedule that defines times at which the switch is to operate in the linked mode and times at which the switch is to operate in the unlinked mode.

21. The solid state lighting switch of claim 12, wherein in the linked mode the dimming indication and the color indication are linked with a type of linking selected by a user from among multiple possible types of linking.

22. The solid state lighting switch of claim 12, wherein the switch comprises a digital addressable lighting interface compatible switch.

23. The solid state lighting switch of claim 12, wherein the switch comprises a wireless interface configured to transmit the color indication and the dimming indication wirelessly to the solid state lighting fixture.

24. A non-transitory computer-readable medium having stored thereon instructions that when executed provide a solid state lighting switch configured for providing a color indication and a dimming indication to a solid state lighting fixture, wherein the instructions when executed provide the solid state lighting switch with:

an input control; and

a selective linking mechanism configured to control whether the switch operates in a linked mode or in an unlinked mode, wherein in the unlinked mode the dimming indication and the color indication are unlinked such that manipulation of the input control causes change to only the dimming indication or only the color indication and wherein in the linked mode the dimming indication and the color indication are linked such that manipulation of the input control causes change to both the dimming indication and the color indication.

25. The non-transitory computer-readable medium of claim 24, wherein in the unlinked mode the dimming indication and the color indication are unlinked such that manipulation of the input control from a first position to a second position causes change to only the dimming indication or only the color indication, and wherein in the linked mode the dimming indication and the color indication are linked such that manipulation of the input control from the first position to the second position causes change to both the dimming indication and the color indication.

26. The non-transitory computer-readable medium of claim 24, wherein the selective linking mechanism is configured to control whether the switch operates in the linked mode or in the unlinked mode in response to a user selection between the linked mode and the unlinked mode.

27. The non-transitory computer-readable medium of claim 24, wherein the selective linking mechanism is configured to control whether the switch operates in the linked mode or in the unlinked mode in accordance with a user-specified schedule that defines times at which the switch is to operate in the linked mode and times at which the switch is to operate in the unlinked mode.
