ABSTRACT:
The inventive surgical light comprises a body provided with main light-emitting diodes and additional light-emitting diodes arranged therebetween, which are spaced on said body and fixed thereto, wherein said additional light-emitting diodes are grouped and are characterised in that the spatial orientation thereof differs from the spatial orientation of the main light-emitting diodes. A light field control device comprises a control unit to which the groups of light-emitting diodes are connected by means of adjusters each of which is connected to a power supply unit. The main light-emitting diodes are fixed to the light body in such a way that the optical axes thereof cross the light axis in the center of a light spot. The additional light-emitting diodes are fixed to the light body in such a way that the optical axes thereof form a concentric light spot in the form of a ring around the main light spot.
