LIGHT EMITTING DIODE LIGHT STRUCTURES

AUSTIN IP PARTNERS, Aust...

1. 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 shunt signal when the rectified
output is less than a threshold voltage, the control circuitry comprising:

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;
a series connected Light Emitting Diode (LED) string comprising a first group of LEDs and a second group of LEDs; and
a switch coupled to a first side of the second group of LEDs and controlled by the shunt signal to deactivate the second group
of LEDs.
