Abstract:
An electronic driver for transforming an electronic ballast input voltage into an operating voltage for an LED lighting module. The driver includes a flicker eliminating circuit, which is adapted to operate in a saturation mode when the input voltage is below a threshold voltage. It operates in a switch mode when the input voltage is above a threshold voltage. A voltage drop in the flicker eliminating circuit in the saturation mode is higher than in the switch mode.
