Controllable-load circuit for use with a load control device

A light-emitting diode (LED) control method, comprising:

• determining, by LED driver control circuitry, whether a phase-controlled, rectified, output voltage is indicative of forward-phase control voltage or reverse-phase control voltage;
• and
• responsive to the determination by the LED driver control circuitry that the phase-controlled, rectified, output voltage is indicative of forward-phase control voltage;
• generating, by the LED driver control circuitry, a first output to enable controllable load circuitry operatively coupled to the LED driver control circuitry;
• causing, by the LED driver control circuitry, a controllable load current to follow the phase-controlled, rectified, output voltage to cause a controllably conductive device to latch during a first period of each half cycle of the phase-controlled, rectified, output voltage;
• reducing, by the LED driver control circuitry, the controllable load current to a determined minimum controllable load current to hold the controllably conductive device in a conductive state during a second period of each half cycle of the phase-controlled, rectified, output voltage;
• and
• causing, by the LED driver control circuitry, the controllable load current to follow the rectified voltage to cause the controllably conductive device to unlatch during third period of each half cycle of the phase-controlled, rectified, output voltage.

A non-transitory, machine-readable, storage device that includes instructions that, when executed by light-emitting diode (LED) driver control circuitry, causes the LED driver control circuitry to:

• determine whether a phase-controlled, rectified, output voltage is indicative of forward-phase control voltage or reverse-phase control voltage;
• and
• responsive to the determination by the LED driver control circuitry that the phase-controlled, rectified, output voltage is indicative of forward-phase control voltage;
• generate a first output to enable controllable load circuitry operatively coupled to the LED driver control circuitry;
• cause a controllable load current to follow the phase-controlled, rectified, output voltage to cause a controllably conductive device to latch during a first period of each half cycle of the phase-controlled, rectified, output voltage;
• reduce the controllable load current to a determined minimum controllable load current to hold the controllably conductive device in a conductive state during a second period of each half cycle of the phase-controlled, rectified, output voltage;
• and
• cause the controllable load current to follow the rectified voltage to cause the controllably conductive device to unlatch during third period of each half cycle of the phase-controlled, rectified, output voltage.
