Classification: CPC H | IPC H

Claim 13:
14. A lighting system comprising:
a light engine comprising a correlated color temperature (CCT) terminal configured to transmit a first power signal having a first variance and to receive a CCT signal, the light engine being configured to emit light according to the CCT signal; and
a CCT clamp coupled to the CCT terminal, and configured to receive the first power signal and to generate the CCT signal having a second variance, the first variance of the first power signal being greater than the second variance of the CCT signal,
wherein the CCT clamp comprises:
a first resistor coupled between the CCT terminal and a first node;
a second resistor coupled between the first node and a common line of the light engine; and
a shunt regulator having a reference terminal coupled to the first node, a cathode terminal coupled to the CCT terminal, and an anode terminal coupled to the common line, the shunt regulator being configured to generate the CCT signal in response to the first power signal.
