Abstract

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.

Claims

1. Operating device for a lighting device, said operating device comprising

an interface via which external dimming values can be supplied to the operating device,

the operating device converting these supplied external dimming values to internal dimming values, on the basis of which controlling of the connected lighting means (LM) device is effected,

the internal dimming values being of a higher resolution than the external dimming values, and

the operating device being designed in such a way that the conversion of the external dimming values into the internal dimming values is programmable.

2. Operating device according to claim 1,

wherein the conversion is programmable in respect of its dynamics so that it is possible to program by which time characteristic response an internal dimming value, assigned to an external dimming value, is achieved.

3. Operating device according to claim 1, wherein

the assignment of an internal dimming value, to be controlled in the stationary state, to an external dimming value is programmable.

4. Operating device according to claim 3, wherein

the lighting device comprises at least one light-emitting diode.
