Ballast-compatible lighting driver and light emitting diode lamp comprising the same

An apparatus comprising:

• a transparent cover;
• a housing to form a first compartment with the transparent cover;
• one or more light emitting diodes disposed inside the first compartment;
• and
• a lighting driver module disposed inside the first compartment and electrically coupled with the one or more light emitting diodes, the lighting driver module comprising:
• a rectifier to convert an AC signal to a DC signal,
• a current sensor configured to measure current supplied to the one or more light emitting diodes and to provide information related to the measured current,
• a first switching device electrically coupled with the rectifier and with the one or more light emitting diodes, and being capable of interrupting or allowing a transmission of the DC signal to the one or more light emitting diodes,
• a controller to switch on or off the switching device to allow or interrupt, respectively, the transmission of the DC signal to the one or more light emitting diodes, based on the information provided by the current sensor, and
• a second switching device, the second switching device being capable of electrically coupling a first end of a first inductor with ground when being switched on, and wherein the controller is further configured to switch on the second switching device when the first switching device is switched off, and to switch off the second switching device when the first switching device is switched on.
