Brief Description
An LED is a two-lead semiconductor light source, which emits lights when activated. When an appropriate voltage is applied to the 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 is determined by the energy band gap of the semiconductor.
How to Use LED?
The forward voltage require to turn ON a LED, depends on it’s color. If you are feeding the exact value of forward voltage then you can connect them 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 Where, VS is the supply voltage VLED is the forward voltage X is the number of LED connected in series ILED is it's current
Check the below table for forward voltage of the LED according to its color
| Color | Forward Voltage |
| Red | 1.63 ~ 2.03V |
| Yellow | 2.10 ~ 2.18V |
| Orange | 2.03 ~ 2.10V |
| Blue | 2.48 ~ 3.7V |
| Green | 1.9 ~ 4.0V |
| Violet | 2.76 ~ 4.0V |
| UV | 3.1 ~ 4.4V |
| White | 3.2 ~ 3.6V |
