Abstract: A surgical lamp for illuminating an operating site includes a lamp body that includes first and second light sources that respectively generate first and second light fields of different diameter on the operating site. When a change in a distance between the lamp body and the operating site is detected, the first and second light intensities of the first and second light sources, respectively, can be controlled such that the predetermined diameter (dx) at which the preset relative central illuminance (Ecx) of the resultant light field is generated is maintained at a substantially constant value as the distance changes.

Abstract: A surgical lamp includes a lamp body with illuminants emitting bundled light beams with axes intersect a central axis of the lamp body, and illuminants emitting bundled light beams with axes that do not intersect the central axis. The shape of the light field and the distribution of the light intensity can be modified by driving different illuminants.

Abstract: A medical supply unit includes a bus system for transmitting instructions of control elements to actuators. The bus system is provided with transmitters and receivers being connected to each other by a transmission system. Via the transmission system, commands of the transmitters are transmitted, which are controlled by the control elements, and the responsive receiver transfers the command to a switching instruction at an output of the responsive receiver so as to control an actuator.

Abstract: A surgical lamp includes a lamp body with illuminants. Axes of bundled light beams emitted by the illuminants intersect a central axis at different positions along the central axis.

Abstract: A surgical lamp includes a light source, a camera, at least one rotatable polarization filter, and a control device that controls the polarization filter according to the results of an evaluation of the image which is captured by the camera.
