The " Light Emitting Diode " or LED as it is more commonly called, is basically just a specialised type of diode as they have very similar electrical characteristics to a PN junction diode. This means that an LED will pass current in its forward direction but block the flow of current in the reverse direction.

LEDs (that's "ell-ee-dees") are a particular type of diode that convert electrical energy into light. In fact, LED stands for "Light Emitting Diode." (It does what it says on the tin!) And this is reflected in the similarity between the diode and LED schematic symbols: In short, LEDs are like tiny lightbulbs.

LED Voltage Drop by Color [Chart by Electrical Engineering XYZ]

The LED voltage would be calculated as follows: LED Voltage = 2.2 volts + (20 mA * 100 ohms) = 2.2 volts + 2 volts = 4.2 volts. This means that a voltage of approximately 4.2 volts is required to power the LED at the desired current of 20 mA. The LED Voltage Calculator simplifies the process of determining the appropriate voltage for powering.

The V F is the voltage used up by the LED, or dropped, when current is traveling in the appropriate direction, forward. The forward voltage rating has to be met in order to light the LED, and that rating varies according to the LED color.

Chart by Colour Here is a chart showing the forward voltage by colour for commonly available LEDs on eBay. These are very cheap now and you can get a bag of high brightness light emitting diodes for virtually pennies. All of these are available in 3 mm, 5 mm, and 10 mm sizes. The cathode lead is typically 17 mm long, whilst the anode is 19 mm long.

LED Series Resistor Calculator How To Calculate Resistor Value For

[6] High Power LEDs commonly work at 3.0-3.6 Volts and require 0.35 ~ 1.0 Amperes per chip. High voltage types typically work at 6, 9, 12, 18 or 36 Volts and require 0.15 ~ 0.30 Amperes per chip. This is either achieved by stacking multiple chips in a single package (like a LED module) or using special production process.
