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. The color of the LED is determined by the energy band gap of the semiconductor.


How to Use a LED?

How to Use 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) / ILED

VS is the supply voltage
VLED is the forward voltage of LED
X is the number of LED connected in series
ILED is LED current


Check the below table for forward voltage of the LED according to its color
