LED is an efficient light emitting diode device, which has to work in a constant current of direct current in order to continuously and steadily emit bright light to illuminate the world. The advantages and disadvantages of the driving power will directly affect the luminance and the quality of the light. How to choose a good LED filament driving power is the key to the manufacture of a good LED filament lamp.

At present, there are three kinds of power supply for using LED filament lamps.

The first is the resistance and capacity reducing power supply that is to be eliminated.

Two is the current mainstream non isolating switch constant current drive power supply.

Three is a new high voltage linear constant current drive power supply.

At present, the main products of LED filament lamps are C35 candle lights and A60 bulb lamps. They can be used to install and drive the power supply in a very small space.
