LED

LED

Circuit model A

Cleaning:

Use alcohol-based cleaning solvents such as isopropyl alcohol to clean the LED.

(A) Recommended circuit.

(B) The difference of brightness between LED could be found due to the VF-IF characteristics of LED.

ESD(Electrostatic Discharge):

Static Electricity or power surge will damage the LED. Use of a conductive wrist band or anti-electrosatic

glove is recommended when handing these LED. All devices, equipment and machinery must be properly

grounded.

Circuit model B

Drive Method:

LED is a current operated device, and therefore, requirer some kind of current limiting incorporated into

the driver circuit. This current limiting typically takes the form of a current limiting resistor placed in series

with the LED.

Consider worst case voltage variations than could occur across the current limiting resistor. The forwrd

current should not be allowed to change by more than 40 % of its desired value.
