Title
(DE) Dimmbares Betriebsgerät mit interner Dimmkennlinie
(EN) Dimmable control device with internal dimming characteristic curve
(FR) Appareil de fonctionnement à gradation doté d'une ligne de référence de gradation interne
Abstract
(DE)
Die vorliegende Erfindung bezieht sich auf ein Betriebsgerät (BG) für Leuchtmittel (LM), welches eine Schnittstelle (IF 1 ) aufweist, über die dem Betriebsgerät (BG) externe Dimmwerte zuführbar sind. Das Betriebsgerät (BG) setzt diese zugeführten externen Dimmwerte in interne Dimmwerte um, auf deren Grundlage die Ansteuerung der angeschlossenen Leuchtmittel (LM) erfolgt. Dabei ist das Betriebsgerät dazu eingerichtet, eine Dimmwertbeschränkung unterhalb von 100% auf einen, insbesondere über einen DALI-Bus und vorzugsweise über die Schnittstelle (IF 1 ), zuführbaren Befehl hin festzulegen, insbesondere zu programmieren, die selektiv einschaltbar, veränderbar und/oder aufhebbar ist.

(EN)
The invention relates to an operating device (BG) for lamps (LM), comprising an interface (IFi), by means of which the device (BG) may be provided with external dimming values. The device (BG) converts said provided external dimming values into internal dimming values on the basis of which the control of the connected lamps (LM) is achieved, the internal dimming values being of higher resolution than the external dimming values. According to the invention, the operating device (BG) is designed such that the conversion of the external dimming values into internal dimming values may be programmed. The operating device (BG) can particularly also be designed such that said conversion can be programmed with regard to the dynamics thereof. A programming can be provided by a time conversion relationship (linear, logarithmic or exponential time curve etc. ) by means of which an internal dimming value corresponding to an external dimming value is reached.

(FR)
L'invention concerne un appareil de commande (BG) destiné à des moyens lumineux (LM) et comprenant une interface (IFi) servant à transmettre des valeurs de gradation de lumière externes à l'appareil de commande (BG). L'appareil de commande (BG) convertit ces valeurs de gradation de lumière externes transmises en valeurs de gradation de lumière internes sur la base desquelles les moyens lumineux raccordés (LM) sont commandés. Ce faisant, les valeurs de gradation de lumière internes ont une résolution supérieure à celle des valeurs de gradation de lumière externes. L'appareil de commande (BG) selon l'invention est en outre conçu de sorte que la conversion des valeurs de gradation de lumière externes en valeurs de gradation de lumière internes soit programmable. L'appareil de commande (BG) peut notamment aussi être conçu de façon que la dynamique de cette conversion soit programmable. Ainsi, on peut prévoir de rendre programmable le comportement de transition temporel (courbe de temps linéaire, logarithmique ou exponentielle, etc.) grâce auquel on obtient une valeur de gradation de lumière interne associée à une valeur de gradation de lumière externe.
