6. Drive Method

An LED is a current-operated device. In order to ensure intensity uniformity on multiple LEDs

connected in parallel in an application, it is recommended that a current limiting resistor be

incorporated in the drive circuit, in series with each LED as shown in Circuit A below.

(A) Recommended circuit

(B) The brightness of each LED might appear different due to the differences in the I-V characteristics

of those LEDs

7. ESD (Electrostatic Discharge)

Static Electricity or power surge will damage the LED.

Suggestions to prevent ESD damage:

 Use a conductive wrist band or anti- electrostatic glove when handling these LEDs

 All devices, equipment, and machinery must be properly grounded

 Work tables, storage racks, etc. should be properly grounded

 Use ion blower to neutralize the static charge which might have built up on surface of the LEDs

plastic lens as a result of friction between LEDs during storage and handing
