Green led efficiency
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. WebSo it has an efficiency of 23.7%. That's pretty simple right? Now with visible light LED, you usually get a figure like lumen or candela. Which are based on the weighting of our eye. And things will get complicated. So the next easy step is …
