First Claim
1. A Light Emitting Diode (LED) light system comprising:
- a LED light including;
a bridge rectifier configured to convert an alternating current power source to a rectified output;
control circuitry configured to produce a plurality of shunt signals based upon a voltage of the rectified output; and
a series connected Light Emitting Diode (LED) string coupled directly across first and second outputs of to the bridge rectifier, the series connected LED string having a primary group of LEDs and at least one secondary group of LEDs; and
a switch coupled to the plurality of secondary group of LEDs and controlled by the shunt signal to selectively deactivate the at least one secondary group of LEDs;
a communication module; and
a controller configured to control the LED light based upon interaction with the communication module.

Abstract
A Light Emitting Diode (LED) light includes a bridge rectifier configured to be powered by an alternating current power source and to produce a rectified output. Control circuitry couples to the bridge rectifier and is configured to produce a shunt signal when the rectified output is less than a threshold voltage. A series connected Light Emitting Diode (LED) string includes a first group of LEDs and a second group of LEDs. A switch couples to a first side of the second group of LEDs and is controlled by the shunt signal to deactivate the second group of LEDs. The control circuitry may include a ratio metric series resistor string configured to sense a proportion of the rectified output and an inverter configured to generate the shunt signal based on the proportion of the rectified output.
