120 Volt Led Circuit Board Diagram. Take note of the diode polarity the output of the diode will have to go to the short lead of the led module made before. An antiparallel diode across the led and a series capacitor is probably the lowest loss way of doing this.
The circuit is using four leds to perform as a night lamp. Blinking led circuit 15 volt you will amazed by this blinking led circuit because it will blink 36 volt led from 15 volt. Therefore 31033 93 numbers and for 120v inputs its calculated as 15033 45 numbers.
An antiparallel diode across the led and a series capacitor is probably the lowest loss way of doing this.
Otherwise the structure will not work as it. With a 047uf non polar capacitor the reactance will be 5646 ohms and the current through the led or leds will be 213ma milliamps. A led can be used as an indicator in an ac circuit by wiring it in inverse parallel with a in4148 or similar silicon diode as shown in figure 6 to prevent the led from being reverse biased. When you are operating an led with 3v you have to use minimum 10 ohms resistor.
