Abstract
A lighting system, preferably for use in operating theatres, in which at least one light source is mounted to be movable an adjustable in a single ceiling and/or wall element in the form of a prefabricated module element ( ). The light sources in each module element may be controlled singly or in clusters by means of a control device designed to direct the source or sources to focus at a point defined by an optical, ultrasound or magnetic, radio frequency pointer that is seen by an appropriate sensor/camera system or receiver in the room, and which, via control means, moves the light source to the desired position. The light source consists of light-emitting diodes, halogen bulbs or the end of one or several fiber-optical cables, fixed ion a holder shaped as one half of a cup or a sphere, the holder being arranges to be movable about two perpendicular axes in the xy-plane (the ceiling plane) of the ceiling module ( ). The holder is attached to the ceiling element by means of a gyroscopic suspension system or a ball joint suspension system. On the top of the holder, which is at the back of the ceiling module ( ), there is provided two attachment points ( ) offset by 90° with respect to each other but parallel to the plane of the ceiling when the light beam is directed downwards normal to the ceiling plane (xy-plane), respective linear actuators being articulated to the attachment points for reciprocating movement, so as to rotate the holder about the x-axis and the y-axis, respectively. This can also be done by use of rotary actuators, possibly mounted in combination with a gear unit, which rotate the suspension ball/holder directly about the axis of rotation.
