Systems and methods for controlling solid state lighting during dimming and lighting apparatus incorporating such systems and/or methods

A lighting apparatus comprising:

• a control circuit operatively coupled to a plurality of light-emitting devices (LEDs) and configured to reduce current through at least one first chromaticity LED included in the plurality while increasing current through at least one additional chromaticity LED included in the plurality to cause a color temperature less than about 1800K produced by the plurality of LEDs to vary substantially in conformance with a Planckian locus in response to a dimming control input.

A method of operating a lighting apparatus including a plurality of light- emitting devices (LEDs) comprising at least one first LED configured to emit first chromaticity light, at least one second LED configured to emit second chromaticity light, and at least one additional LED configured to emit additional chromaticity light, the method comprising:

• reducing current through the at least one second LED;
• and
• increasing current through the at least one additional LED, while reducing the current through the at least one second LED, to cause a color temperature produced by the plurality of LEDs to vary substantially in conformance with a Planckian locus in response to a dimming control input.
