led reverse voltage and reverse breakdown voltage

First we need to clear out of two concept— led reverse voltage and reverse breakdown voltage 。

*led reverse voltage: we will call it “reverse voltage” when just make reverse voltage for led, in general there are not have numerical definition for reverse voltage ,and no matter the input voltage how big.,only condition is opposite directed . this is led reverse voltage.

*led reverse breakdown voltage, the most character of led reverse breakdown voltage is that the led reverse breakdown voltage has numerical definition . the PN junction have been zener or avalanche breakdown emerged from led reverse breakdown voltage(when the reverse current meet specification value).this situation we will call it” led reverse breakdown voltage”.
