  • the prior known surgical lighthead comprises a fixed lighthead frame, which is provided with a plurality of light sources, such as halogen lamps or the like, and generally a pivotable spring arm for fixing the lighthead to ceiling structures and for adjusting its position relative to the operating table and a surgical patient resting thereon.
  • the process of directing and manipulating such lighting constitutes one risk factor in surgical procedures performed in operating theatres.
  • the light beams generated by lightheads used for lighting and mounted on ceiling structures, be brought to follow the surgical operation and to focus the light exactly on the surgical site.
  • this is done by deflecting and displacing the lightheads manually in such a way that the light beams impinge on an object of illumination.
  • a first problem with such a manually conducted focusing of light is the disturbance of a supply airflow arriving at the operating table as lightheads are being swiveled and displaced, which may increase the risk of contamination.
  • An objective of the invention was to provide a lighting arrangement capable of eliminating the problems associated with the above-described operating theatre lighting fixtures.
  • a further objective of the invention is to provide a new improved operating theatre lighting arrangement, by means of which spotlighting for an operating table and surgical procedures can be controlled in a way to enable minimal manipulation and swiveling of the lighthead.

This is followed by deflecting the light element 31 through the basic position P0 for directing its light beam 7 in such a way that the center line P is aimed towards a designated spot 61 present in the ear region.
  • What is determined in the control instruction is therefore the driving of a light element to a basic position P0 and thereafter, commencing from the basic position P0, deciding across which angle b1, b2 each light element 31 must be deflected by the directing implements 31 b.
  • steps 620, 630, 640 comprise determining initial positions Pa for the center line P of each light element's 31 light beam 7, as well as a desired focusing position P, and thereafter determining control instructions for the directing implements 31 b in such a way that the light elements 31 are driven directly from the initial position Pa to the desired focusing position P without passing the light elements 31 through the basic position P0 unless this is necessary.
  • step 630 will be revisited. Otherwise, the control unit 8 transmits with its data transfer unit, over a wired and/or wireless communication link, the produced light element-specific control instructions to the directing implements 31 b of each light element 31 for focusing the same on the designated spot 61, thus enabling the desired ear region to be illuminated as intended by the user.
  • control method terminates in step 658.
