Abstract
An operating-room lighting device with an inner lighting unit that includes at least one discharge lamp and an inner reflector in a housing. The lighting unit is at least partially enclosed by an outer annular housing with an annularly or polygonally designed reflector for convergent deviation of light emitted by the lighting unit into an illumination field. The outer reflector includes, on its side facing the inner lighting unit, a closed transparent surface whose back adjoins a reflective layer. The reflective layer is applied to the back of the transparent surface. The inner lighting unit and the outer reflector are held together by a connecting member, which is articulated to a curved intermediate piece for attachment to a stationary support. It is therefore possible to provide an operating-room lighting device having a high illumination intensity, which supplies the illumination field, on the one hand, with light from a large diameter and, on the other hand, from a small diameter, so as to offer both good lighting of narrow wounds and good illumination behind possible obstacles. The lighting unit is furthermore compactly designed and suitable for laminar flow in order to avoid contamination in the environment of the operation-room field.
