Brief Description
An LED is a two-lead semiconductor light source, which emits lights when activated. When an appropriate voltage is applied to the LED terminal, then the electrons are able to recombine with the electron holes within the device and release energy in the form of photons. This effect is known as electroluminescence. Thecolor of the LEDis determined by the energy band gap of the semiconductor.
How to Use a LED?
The forward voltage require to turn ON a LED, depends on the color of the LED. If you are feeding the exact value of forward voltage then you can connect a LED directly to the source. If the voltage is a higher than use a resistance in series with the LED, to calculate the value of the resistance use formula:
R = (VS- VLED* X) / ILEDWhere, VSis the supply voltage VLEDis the forward voltage of LED X is the number of LED connected in series ILEDis LED current
