Surgical light having a variable light field geometry

1. A surgical light comprising a plurality of lights associated with several light groups, wherein a plurality of first lights are associated with a first light group and a plurality of second lights are associated with a second light group, and wherein lights of the same light group each produce a light beam extending along a longitudinal axis and are oriented and arranged in relation to each other in such way that longitudinal axes of light beams of lights of the same light group intersect in a common focal plane, so that longitudinal axes of light beams of the first lights intersect in a first common focal plane and longitudinal axes of light beams of the second lights intersect in a second common focal plane arranged at a distance from the first focal plane,

wherein a control unit is provided which is electrically connected to each first light of the first light group and to each second light of the second light group such that the first lights of the first light group and the second lights of the second light group can be supplied with current independently of each other such that a light field geometry produced by the first lights and the second lights in an illumination plane arranged at a distance from the focal plane can be adjusted, and

wherein the control unit is configured to actuate the first lights and the second lights in at least a first control state by forming an elongate total light field.

2. The surgical light according to claim 1 , wherein the first lights of the first light group and/or the second lights of the second light group are arranged in a common light receiving member.

3. The surgical light according to claim 1 , wherein each of the first lights associated with the first light group or each of the second lights associated with the second light group is formed of a light module comprising an LED.

4. The surgical light according to claim 1 , wherein a respective separate lens is associated with each of the first lights associated with the first light group or with each of the second lights associated with the second light group.

5. The surgical light according to claim 1 , wherein the first lights associated with the first light group or the second lights associated with the second light group can be adjusted independently of each other as to their illuminance.

6. The surgical light according to claim 1 , wherein at least several of the first lights associated with the first light group or at least several of the second lights associated with the second light group are different from each other by their luminous color.

7. The surgical light according to claim 1 , wherein the first lights associated with the first light group or the second lights associated with the second light group are arranged next to each other in a ring shape.

8. The surgical light according to claim 7 , wherein the first lights associated with the first light group are arranged to be spread along a first ring-shaped peripheral line and the second lights associated with the second light group are arranged to be spread along a second ring-shaped peripheral line.

9. The surgical light according to claim 8 , wherein the first peripheral line is arranged inside the second peripheral line.

10. The surgical light according to claim 1 , wherein an operating unit is provided and configured to adjust the light field geometry.

11. The surgical light according to claim 10 , wherein the operating unit includes a speech recognition unit.

12. The surgical light according to claim 10 , wherein the operating unit is connected to the control unit by a wired or wireless data communication.
