Light emitting diode light structures

A Light Emitting Diode (LED) light apparatus comprising:

• a bridge rectifier configured to be powered by an alternating current power source and to produce a rectified output;
• control circuitry coupled to the bridge rectifier, the control circuitry configured to produce a first shunt signal based upon the rectified output and at least one first voltage threshold and to produce a second shunt signal based upon the rectified output and at least one second voltage threshold;
• a series connected Light Emitting Diode (LED) string coupled directly to the bridge rectifier, the series connected LED string having a first group of LEDs, a second group of LEDs, and a third group of LEDs;
• a first switch coupled to a first side of the second group of LEDs and controlled by the first shunt signal to deactivate the second group of LEDs;
• and
• a second switch coupled to a first side of the third group of LEDs and controlled by the second shunt signal to deactivate the third group of LEDs.

A method for operating a Light Emitting Diode (LED) light comprising:

• rectifying, by a bridge rectifier, an alternating current power source and to produce a rectified output;
• producing a shunt signal when the rectified output is less than a threshold voltage;
• and
• for a series connected Light Emitting Diode (LED) string coupled directly to the bridge rectifier, the series connected LED string having a first group of LEDs and a second group of LEDs, closing a switch coupled to a first side of the second group of LEDs by the shunt signal to deactivate the second group of LEDs.
