ED–parameter analysis

About LED–parameter —- although the subject might seem very simply。It really matters for your work. that are purposeful, and that are appropriately sequenced。

1、ForwardVoltage of LED (VF)

Different LED can have different VF. actual data is cited as follows:

* RED & YELLOW 1.8~2.5V；

* GREEN & BLUE：2.7~4.0V;

The VF and luminous intensity could be different Even at the same color.

Ratedcurrent of LED

The Ratedcurrent of LED are many and various， The most frequently used LED is 20 mA。the Ratedcurrent of high-power as 40mA~350mA.

LED power

With the improvement of LED power, we put forward more requirements towards LED power.So it’s much more type for your requirement.most common types are 70mW、100mW、1W、2W、3W、5W. Our customers can choose that LED power according to the requirements. shall be determined through reasonable evaluation methods by referring to the base schematics。

Most of the damage that’s occurred was input voltage or input current are too high. Damage mean that shorten service time 。the way could no longer be used. But the led light-illuminance will be affecte If the voltage level is too low.

Integrated above, This is an improper usage would be unable to play its full role。Familiar with LED specification is very important for we can be a better application of LED
