ABSTRACT:
The invention relates to a luminaire comprising a plurality of light sources fixedly located in a plurality of positions and comprising at least an electroluminescent diode. Said sources are focused by the same optical system fixed relative to the plurality of sources. Said luminaire comprises electronic means for dimming sources in their emission intensity independently of one another and as a function of their respective positions relative to said optical system. The invention provides an output beam having a dimmable photometric distribution in time and in space at the output of said optical system.
