Abstract:
A control circuit for a light emitting diode (LED) lighting system for achieving a dim-to-warm effect is provided. The control circuit includes an LED controller, a clamp circuit coupled to a set of warm correlated-color-temperature (“CCT”) LEDs, a switch coupled to a set of cool LEDs, and a feedback circuit coupled to the clamp and the switch. The LED controller is configured to control the clamp circuit to clamp current through the set of warm LEDs based on the input current, and control the switch to switch on the set of cool LEDs responsive to the input current being greater than a first threshold level and to switch off the set of cool LEDs responsive to the input current being lower than the first threshold level. The feedback circuit is configured to divert current from the set of warm LEDs to the set of cool LEDs.

Claim (Index 17):
A control circuit for a light emitting diode (LED) lighting system, the control circuit comprising:\n a clamp circuit coupled to a set of warm correlated-color-temperature (\u201cCCT\u201d) LEDs; a switch coupled to a set of cool CCT LEDs; an LED controller configured to:\n obtain a current magnitude of an adjustable input current; \n disconnect the cool CCT LEDs via the switch if the current magnitude is below a first current threshold such that the adjustable input current flows through the set of warm CCT LEDs; \n control the clamp circuit to clamp current through the set of warm CCT LEDs to a constant clamp current level if the adjustable input current is adjusted to be above the first current threshold but remains below a second current threshold; \n close the switch to enable a portion of the input current to flow through the set of cool CCT LEDs if the adjustable input current is adjusted to be above the first current threshold but remains below a second current threshold: \n progressively reduce the current through the set of warm CCT LEDs to zero if the adjustable input current is above the second current threshold and increasing past the second current threshold to a maximum current; and \n increase the input current flowing to the set of cool CCT LEDs to the maximum current if the adjustable input current is above the second current threshold and increasing past the second current threshold to the maximum current, wherein increasing the input current flowing to the set of cool CCT LEDs comprises diverting the current from the set of warm CCT LEDs to the set of cool CCT LEDs.
