LEDs (light emitting diode) are essentially diodes that use only electrical current flowing in one direction, commonly known as direct current. In conventional LED lights, a converter circuit, called a driver, is required to convert the high AC voltage to a lower DC voltage with a constant current for the LED light engine. However, the converter circuit not only increases costs but also shortens the lifespan of the LED lights.
However, AC (alternative current) LEDs can be connected directly to normal power supplies (usually 110V at 60Hz or 230V at 50Hz) and do not require a driver, like normal LEDs. The sinusoidal waveform circuit means that at each particular time half the LEDs are off while the other half is on, emitting light. This stage is reversed and repeated continually and, thus producing a constant stream of light.
