3.9.1 Dynamic dimming procedures with amalgam lamps
The frequency of dimmer setting changes is primarily limited by the
inertia of the control input, a passage of the dimming range takes ap-
prox. 200 ms for 1…10 V, and approx. 50 ms for DALI. Thus, rapid
flashing blurs to a middle dimmer setting. At 10 Hz, this effect is al-
ready particularly visible at 1…10 V. No damage to the lamp is to be
expected. A dimming process every 2 s is possible without any prob-
lem.
