Circuit of led light

This gadget can be used in applications like night light , table lamp etc. Automatic LED Emergency Light -Modified Version. For example, a green LED is sensitive to blue light and to some green light , but not to yellow or red light.

This implementation of LEDs may be added to designs with . You must make some calculations to figure out the resistor value, depending on voltage power supply, LED voltage drop and desired current.

Source Voltage – LED Voltage Drop) .

It can give ample light even for reading purpose.

The functionality of LED is as same as normal diode but it emits light when current passes through it. However, a special feature of this device is its ability to emit energy in the visible band of the electromagnetic spectrum i. A major concern to drive an LED is to provide an almost constant current input. Often, an LED is driven using batteries or control devices like microcontrollers.
