Surgical light and method for operating a surgical light

A surgical lamp for illuminating a surgical field on a human body, the surgical lamp having:

• a control device,
• a lamp body comprising
• several illuminants with one respective light ray (I, II, II′) directed to the surgical field, and
• a 3D sensor for detecting a spatial position of at least one object, and devices for switching on and off and dimming the illuminants,
• wherein the control device controls the devices for switching on and off and dimming the illuminants,
• the 3D sensor detects the spatial position of the at least one object and transmits corresponding data to the control device,
• the control device is configured to control the illuminants according to the spatial position of the at least one object,
• the 3D sensor detects the spatial position and a size of the at least one object between the lamp body and the surgical field,
• the control device is configured, due to the spatial position and the size of the at least one object, to dim or to switch off the illuminants, the respective light ray (I, II, II′) of which is directed to the at least one object, and to operate the illuminants, the respective light ray (I;
• II;
• II′) of which is directed past the at least one object to the surgical field, and
• the control device is configured to predict an expected position of the at least one object at a certain point of time from the spatial position and the motion of the at least one object and to control the illuminants depending on the predicted positon and the size of the at least one object such that the illuminants, the respective light ray (I, II;
• II′) of which is then directed to the at least one object in the predicted position, are dimmed or switched off at the certain point of time, and the illuminants, the respective light ray (I;
• II, II′) of which is then directed past the at least one object in the predicted position to the surgical field.
