a light emitting diode led is a semiconductor device that emits visible light when an electric current passes through it the light is not particularly bright but in most leds it is monochromatic occurring at a single wavelength
In electronics, an LED circuit is an electrical circuit used to power a light-emitting diode (LED). The circuit must provide sufficient current to light the LED at the required brightness, but must limit the current to prevent damaging the LED.The voltage drop across an LED is approximately constant over a wide range of operating current; therefore, a small increase in applied voltage greatly increases the current.he circuit must provide sufficient current to light the LED at the required brightness, but must limit the current to prevent damaging the LED.
