(one time only) 5. 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 re sistor be incorporated in the drive circuit, in series with each led as shown in circuit a below. circuit model a circuit model b led led (a) recommended circuit. (b) the brightness of each led might appear different due to the differences in the i -v characteristics of those leds. 6. esd (electrostatic discharge) static electricity or power surge will damage the led. suggestions to prevent esd damage: use of 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 handling.
