A lighting system (10) suited to use in an operating theater includes one or more lightheads, each having a housing (28) and a bezel (50) extending therefrom. A light source (38) is disposed within the housing. A handle (36) extends below the bezel and is rotatable relative thereto. A lighting control input means (60), associated with the bezel allows adjustment of the intensity of light emitted by the light source. A sterile cover (54) can be placed over both the handle and the bevel, allowing the input means to be manipulated by pressure on the cover with the thumb of the operator's hand, while simultaneously grasping the handle in the palm and fingers.

La présente invention concerne un système d'éclairage (10) conçu pour utilisation en bloc chirurgical. Ce système est pourvu d'une ou plusieurs têtes d'éclairage dont chacune comporte un logement (28) et une couronne de fixation (50) dépassant du logement. Une source de lumière (38) est disposée à l'intérieur di logement. Une poignée (36) dépassant en dessous de la couronne est capable de rotation par rapport à cette dernière. Un organe d'entrée de commandes d'éclairage (60), associé à la couronne, permet de régler l'intensité de la lumière émise par la source de lumière. On peut mettre une protection stérile (54) recouvrant la poignée et la couronne, ce qui permet à l'opérateur de manipuler à la main l'organe d'entrée en exerçant sur la protection une pression du pouce, tout en saisissant la poignée entre la paume et les doigts.
