Green led calculator
WebThe most popular type of tricolour light emitting diode comprises of a single Red and a Green LED combined in one package with their cathode terminals connected together producing a three terminal device. They are called tricolour LEDs because they can give out a single red or a green colour by turning “ON” only one LED at a time. WebThis LED calculator will help you design your LED array and choose the best current limiting resistors values. To get started, input the required …

Often, a red LED's forward voltage is ~2V, a green one ~3V, and a blue one is ~3.4V, but it really does depend on the LED manufacturer and the exact frequency of the light emitted. Once you know the forward voltage of an LED, you can …
