Patent ID: 8823630

Claim:
A method of controlling a solid state lighting panel utilizing a microcontroller, the method comprising: receiving, in the microcontroller, a color management reference value corresponding to a color characteristic of the solid state lighting panel; estimating a color management change value using the color management reference value; comparing the color management change value to a threshold value; and adjusting a control mode of the microcontroller responsive to the color management reference value, wherein the control mode includes a closed loop control mode that performs control operations based on a reference value and a feedback signal and an open loop control mode that adjusts the solid state lighting panel based on the reference value without the feedback signal, wherein adjusting the control mode comprises operating the microcontroller in the closed loop control mode responsive to the color management change value being greater than the threshold value, and wherein adjusting the control mode further comprises operating the microcontroller in the open loop control mode responsive to the color management change value being less than or equal to the threshold value.
