Chofè ki gen kapasite kapasite pou domaje pwodiksyon limyè dirije sou ranje a plen soti nan 100% a 0%. Chofè diminye ka dim poul pa rediksyon nan pi devan aktyèl la, batman modulasyon lajè (PWM) atravè kontwòl dijital, oswa plis metòd sofistike. Pifò chofè adaptab opere lè l sèvi avèk metòd la PWM. Avèk metòd sa a, frekans lan ta ka varye soti nan yon modulasyon san pou chak dezyèm jiska kòm dè santèn de milye de modulasyon pou chak dezyèm, se konsa ke dirije a parèt yo dwe kontinyèlman limen san yo pa tranbleman.

Drivers with dimming capability can dim the LED light output over the full range from 100% to 0%. Dimming drivers can dim LEDs by reduction in the forward current, pulse width modulation (PWM) via digital control, or more sophisticated methods. Most dimming drivers operate using the PWM method. With this method, the frequency could range from a hundred modulations per second to as high as hundreds of thousands of modulations per second, so that the LED appears to be continuously lighted without flicker.
