The voltage and current of LED

 

First we have the introductions

the yellow(585-595nm)﹑Red(600-650nm) and green(565-575nm) :

Their voltage is 1.8~2.4V(outside the range).and the vavg as 2.0v.

The blue(585-595nm)﹑green (600-650nm) and write(565-575nm) :

Their voltage is 2.8~4.0V(outside the range).and the vavg as 3.3v.
