Patent ID: 8581810

Claim:
A circuit comprising: one or more LED drivers configured for coupling to one or more LEDs and configured to regulate operation of the one or more LEDs, wherein the LED drivers are configured to receive a drive voltage from a power supply; a programmable decentralized controller coupled to the power supply and one or more detectors, wherein the one or more detectors are configured to detect one or more measurable parameters of the one or more LEDs or LED drivers; said controller configured to control the power supply to set the drive voltage; said controller configured to receive information from the one or more detectors related to the one or more measurable parameters; said controller configured to adjust one or more controllable parameters until one or more detectors indicate that one or more measurable parameters in one of the LEDs or LED drivers meet a reference condition; and said controller configured to set one or more of the controllable parameters to operate at a value relative to the value of the controllable parameters at which the reference condition was met.
