FAQ

How do I connect a led to an 220V AC power source?
The resistance is generally around 50K, depending on the brightness required.
How do I connect the led to the 12V AC?
Connect it to the AC circuit, you can not consider the zero FireWire, nor consider the positive and negative poles, but you are in series when you want to split the positive and negative poles, as well as reverse voltage, may burn out light-emitting diodes.
AC LED through AC 220 why not flashing?
LEDs can use either direct current or alternating current;When the DC power is used, the LED is connected in a direction, and the positive pole of the DC power supply must be connected with the positive end of the light-emitting diode (or the positive electrode of the led by a step-down resistor);
