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 20):
A method comprising:\n receiving an increasing adjustable analog current at an input of a dim to warm circuit; disconnecting a cool LED such that the adjustable analog current is provided to a warm LED while the adjustable analog current is below a first input current; providing a first adjustable portion of the adjustable analog current to the cool LED and a clamped portion of the adjustable analog current to the warm LED, such that the first adjustable portion is determine based on the adjustable analog current and the clamped portion remains constant while the adjustable analog current is between the first input current and a second input current; and providing a second adjustable portion of the adjustable analog current to the cool LED and a third adjustable portion of the adjustable analog current to the warm LED, such that the second adjustable portion and the third adjustable portion is determined based on the adjustable analog current, while the adjustable analog current is greater than the second input current.
