The electronics part of an LED—the driver—seems to be an indispensable part of it. But it’s no longer so. According to experts, drivers are no longer needed to power an LED light. It can now be powered directly from AC mains. These LEDs are also called driver-free AC LEDs.
AC LED technology makes LEDs work directly by AC100/240v, without any driver. These LEDs can be connected directly to normal power supplies (usually 110V at 60Hz or 230V at 50Hz). The sinusoidal waveform circuit means that at each particular time half the LEDs are off while the...

atented Driverless LED Bulbs to replace traditional lamp
What is driverless? What is a driver?
In ordinary LED bulbs,the driver converts 240 volt AC mains power to DC volts,which LEDs can use.It is complicated device typically containing more than one hundred electronic parts: capacitors,resistors,temperatures sensors and chips.These generate significant amounts of heat.
Our measurements of competitor bulbs reveal temperatures,averaged over the bulbs,between 60°C to 80°C.This is electricity wasted in the production of heat,not light.
That's not only problem with normal LED Bulbs.The reason they can't...
