Abstract
A medical lighting device for illuminating an operative field, which device includes light-emitting diode (LED) light sources that cooperate with collimator optical systems to light the operative field. LEDs are mounted on a flat printed circuit board so that their illumination axes (B) passing through the collimator optical systems (7) have different angular orientations. The printed circuit board (6) may be cut out to form tongues, each of which is flexible and has a free end carrying an LED. Each tongue can be deformed under stress in such a manner that its free end is oriented substantially perpendicularly to the illumination axis (B).
