<p>A controller and a method for controlling lamp drivers such as e.g. LED drivers for lamps having a fast response behavior such as e.g. LED lamps are proposed. They enable to substantially reduce or prevent a visible luminance flicker at such lamps when dimming the lamps with a conventional dimmer such as e.g. a phase cut dimmer. This can be achieved by switching off the lamp driver prematurely in such a way that a time jitter of a dimmer switching does not influence an on-time of the lamp driver. No bulky or expensive filters or capacitors are needed. Thus, a space-saving and/or inexpensive construction is enabled.</p> |
