Why should we will do my best to protect led ?

Because of it is species advantage ,led is playing an important role in more and more area. we know that led (Light Emitting Diode) is kind of solid Semiconductor. led might able to make electricity energy to light energy. led belong to device of voltage sensitive. led service time is so long when led is used in a right way. the follows note ismore than anything,

Protects led from damage of electromagnetic wave and static;electrostatic hazard to led equipment in led labs is one of the malfunctions most difficult to eliminate. we should be recognized to prevent static damage to led during assembly work.

The led factory setup can be max in 20mA,the growth of the voltage becomes slower with current increase
