Claim of US Patent No. 10,893,584

10. A method for controlling a plurality of light fixtures, the method comprising:coupling first electrical elements within a control loop to a first power source and a first ground, the control loop including a first op-amp;
coupling second electrical elements within an output loop to a second power source and a second ground, the output loop including a second op-amp, wherein the first power source and the second power source are electrically isolated from each other and the first ground and the second ground are electrically isolated from each other; and
electrically isolating the control loop and the output loop with an optical isolator, the optical isolator being configured to receive an input signal from the control loop and transmit an output signal to the output loop,
wherein the first power source and the second power source are configured to supply a same voltage.
