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.
