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.

Abstract: The aim of the invention is to increase the accuracy of adjustment by simplifying the adjustment of each light-optical module of a lighting device. The aim is attained by means of the inventive light-optical module comprising an annular holder provided with a core which is arranged in the center thereof and connected thereto by three strengthening ribs, a reflector and a light-emitting element embodied in the form of a light-emitting diode. Said light-emitting diode is arranged in a nest embodied in the core on the reflector side. The annular holder is connected to the reflector by means of a threaded joint and the mounting surface thereof arrangeable in the lighting device body is shaped in the form of a cone. The inventive annular holder, the core and the strengthening ribs are made of a heat-conducting material.
