The main goal is to develop and envelope efficient universal input LED lamp driver with high power factor to avoid any potential pollution to the grid. The conventional electrolytic capacitor for energy storage in the circuit will be eliminated to improve the reliability of the LED driver.  The following characteristics will be achieved:  Maximum efficiency of the driver with AC input  Universal input  High power factor low input current THD  No electrolytic capacitor in the power stage (E-capless)  Isolated between output and input  Wireless dimming function  Low cost  High life-time
