Led Night Lamp Circuit Diagram. The circuit is using four leds to perform as a night lamp. It s likely though you ve already read the wikipedia page about series and parallel circuits here maybe a few other google search results on the subject and are still unclear or wanting more specific information as it pertains to leds.
The circuit is using four leds to perform as a night lamp. The capacitor c1 and resistor r1 forms the current limiting circuit. Here you have the circuit diagram of a simple night light on the left side you can observe the voltage divider that will control the mosfet by providing more than 3v on night making the led to light and less than 2v when is daytime turning the mosfet off and closing the led light the mosfet can be changed with a regular transistor but because the mosfet is different than a transistor we will gain some power consumption.
Bridge d1 is used to rectify the ac mains voltage.
It s likely though you ve already read the wikipedia page about series and parallel circuits here maybe a few other google search results on the subject and are still unclear or wanting more specific information as it pertains to leds. An led is an important component in electronics it is used for several indi. Here is a simple led night light circuit which can be used as a room night lamp. In this circuit we will connect three 5mm white leds is series with the same 12v supply.
