Operating theatres and recovery rooms
Surgical operations present the greatest challenges of all for physicians and medical personnel, particularly in terms of visual performance. For this reason, special surgical luminaires meeting the specifications of DIN EN 60601-2-41 are used to provide 10,000 - 160,000 lux in the operating field.
To avoid adaptation problems for the human eye when lines of sight switch between the operating field and the surrounding area, the illuminance of the room lighting needs to be graduated. Up to 2,000 lux in the immediate vicinity of the operating table facilitates adaptation. This lighting needs to be provided in addition to the general room lighting rated at 1,000 lux illuminance.
Surround lighting prevents problems of adaptation arising from the marked difference in luminance between the operating field lighting and the general lighting.
