Abstract
A system integrates a wireless controller into a linear, alternating current-only driver. The system utilizes a light emitting diode driver to maintain a constant current to a light emitting diode when a current controller is operated by a pulse width modulated signal. The pulse width modulated signal to one or more light emitting diode circuits may be modified to reduce flicker, color mix, and temperature tune.
