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.

Circuit model A

(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
