Apparatus, method and system for providing ac line power to lighting devices

An apparatus comprising:

• a plurality of light emitting diodes couplable to receive an alternating current (AC) voltage, wherein the plurality of light emitting diodes is further couplable to form a plurality of segments, each segment including one or more light emitting diodes;
• and
• a control circuit configured to control actuation of the plurality of light emitting diodes, wherein the control circuit is configured to:
• cause, during a first time interval, a first segment of the plurality of segments to be included in a light emitting diode current path;
• determine whether sufficient time remains in the first time interval for light emitting diode current to reach a predetermined peak level if a second segment of the plurality of segments is included in the light emitting diode current path;
• and
• based on the determination, cause, during the first time interval, a second segment of the plurality of segments to be included in the light emitting diode current path.

A method comprising:

• causing, during a first time interval, a first segment of a plurality of segments to be included in a light emitting diode current path, wherein a plurality of light emitting diodes is couplable to receive an alternating current (AC) voltage, the plurality of light emitting diodes is further couplable to form the plurality of segments, wherein each segment includes one or more light emitting diodes;
• causing, during the first time interval, a second segment of the plurality of segments to be included in the light emitting diode current path, wherein the second segment is different from the first segment in at least one characteristic;
• and
• causing, during a second time interval different from the first time interval, one or both of the first or second segments to be removed from the light emitting diode current path.
