Abstract
A light-emitting diode (LED) bulb comprises a base and a shell connected to the base. A first set of LEDs is disposed within the shell and is configured to emit light at a first color corresponding to a first black-body color temperature. A second set of LEDs is also disposed within the shell and is configured to emit light at a second color corresponding to a second black-body color temperature that is different from the first black-body color temperature. A control circuit is configured to provide a transitional-power state to the first and second sets of LEDs to transition between an initial-power state and a reduced-power state by producing a shifting color output that corresponds to a predetermined light-output curve.
