Abstract: An AC LED is an LED that operates directly off of AC line voltage while a DC LED uses a driver to convert the line voltage to direct current (DC) power. A light emitting diode (LED) is a semiconductor device which includes an N-type semiconductor and a P-type semiconductor, and emits light by way of recombination of holes and electrons.

A: Zero to ten volt (stylized as 0-10v) is actually one of the earliest signaling system invented for lighting control and is also one of the simplest: it uses a control signal of low voltage that ranges from 0 to up to a maximum 10 volts. The amount of volts sent to the LED driver, tells it how bright to be. Send 0 volts and the light is off. Send 10 volts and the light will go to maximum power.Get a Quote

Since many alternative energy sources as well as electronics and controls technologies are based on DC current, DC grids have been investigated more intensely in the last decade. DC grids with a centralized AC/DC conversion have proven to be advantageous in server farms. While LED lighting is also a DC current related technology, an obvious choice would be to use DC grids for them.
