    Abstract: Lighting apparatus includes a first string of light-emitting diodes (LEDs) having a first terminal coupled to a current source and configured to produce a first correlated color temperature (CCT) and a second string of LEDs having a first terminal coupled to the current source and configured to produce a second CCT different from the first CCT. The lighting apparatus further includes a current control circuit coupled to second terminals of the first and second strings of LEDs and configured to vary a proportionality relationship between current levels in the first and second strings of LEDs responsive to variation in a current provided by the current source to the first terminals of the first and second strings of LEDs. The current control circuit may include a current mirror circuit and a control circuit configured to selectively enable and disable the current mirror circuit.

    Abstract: A solid state lighting switch can include a first input control that can be configured to adjust a dimming indication or color indication for a solid state lighting fixture that is configured for coupling to the solid state lighting switch. A selective linking mechanism can be configured to activate a linked mode of operation of the switch to link the dimming indication to the color indication or to activate an unlinked mode of operation of the switch to unlink the dimming indication from the color indication.
