Abstract

A controller is configured to generate one or more power control signals for a lamp to supply power to the lamp from a supply voltage. The controller is further configured to receive customization data encoded in the supply voltage. Thus, in at least one embodiment, the controller receives the customization data via one or more power terminals of the lamp. Phase cut angles in the supply voltage provided to the controller encode the customization data, and each phase cut angle encodes N symbols of data. N is an integer greater than or equal to one (1). In at least one embodiment, the customization data alters the controller from one state to another state in accordance with data represented by phase cuts in the supply voltage that encode the customization data. Examples of customization data include calibration data and configuration data.

Claims

1. An apparatus comprising:

a controller configured to generate one or more power control signals for a lamp to supply power to the lamp from a supply voltage, wherein the controller is further configured to receive customization data to customize the controller via one or more power terminals of the controller, wherein phase cut angles in the supply voltage to the controller encode the customization data, each phase cut angle represents a symbol and each symbol encodes N characters of data, and N is an integer greater than or equal to one (1).

2. The apparatus of claim 1 wherein at least a subset of the symbols represent bits, and for the symbols representing bits N is greater than or equal to two (2).

3. The apparatus of claim 1 wherein phase cut angles of the supply voltage equal to approximately 0 degrees are not used to encode the customization data.

4. The apparatus of claim 1 wherein the controller includes:

a physical media attachment module to decode the phase cut angles of the supply voltage into data; and

a physical coding module, separate from the physical attachment module, to validate and interpret the data.

5. The apparatus of claim 1 further comprising:

a memory, coupled to the controller, to store the customization data.

6. The apparatus of claim 1 wherein the controller includes a memory to store the customization data.

7. The apparatus of claim 1 wherein the supply voltage is rectified, and the phase cut angles that encode the customization data are at angles of the supply voltage between approximately 20 degrees and approximately 160 degrees.

8. The apparatus of claim 1 wherein the controller is further configured to utilize the customization data to regulate at least a member of a group consisting of the intensity of light from the lamp and a color spectrum of the lamp.

9. The apparatus of claim 1 wherein the controller is further configured to utilize the customization data to regulate one or more operational modes of the lamp.

10. The apparatus of claim 9 wherein the operational modes of the lamp include at least one member of a group consisting of multiple color modes, one or more light flicker modes, and multiple dimmer compatibility modes.

11. The apparatus of claim 1 wherein the controller is further configured to write the customization data to a volatile memory during a customization process, provide feedback to a customization unit representing actualization of at least a portion of the customization data, and write operating customization data to a non-volatile memory.

12. The apparatus of claim 1 wherein the supply voltage is phase cut and maintains direct current (DC) balance.

13. The apparatus of claim 1 wherein the customization data comprises calibration data to calibrate the controller.

14. The apparatus of claim 1 wherein the customization data comprises configuration data to configure features of the controller.

15. The apparatus of claim 1 further comprising:

a switching power converter coupled to the controller; and

one or more light emitting diodes coupled to the switching power converter.

19. The method of claim 1 wherein the controller includes:

decoding the phase cut angles of the supply voltage into data in a physical media attachment module of the controller; and

validating and interpreting the data in a physical coding module, separate from the physical attachment module.

16. A method comprising:

receiving customization data to customize the controller via one or more power terminals of a controller, wherein phase cut angles in a supply voltage to the controller encode the customization data, each phase cut angle represents a symbol and each symbol encodes N characters of data, N is an integer greater than or equal to one (1), and the controller is configured to generate one or more power control signals for a lamp.

17. The method of claim 16 wherein at least a subset of the symbols represent bits, and for the symbols representing bits N is greater than or equal to two (2).

18. The method of claim 16 wherein phase cut angles of the supply voltage equal to approximately 0 degrees are not used to encode the customization data.
