<p>The invention concerns a lighting device for operative site without cast shadow, particularly, but not exclusively, designed for dental surgery, comprising a lighting head (1) supplied with light by at least one of the optical fibre cords (2) conducting light produced by a light generator (3) placed at some distance from the lighting head (1). The invention is characterised in that the light generator (3) comprises a mechanical system for spacing or bringing closer a tip (15) from which the cords (2) originate relative to a lamp (16) of the light generator (3). Preferably, the lighting head (1) comprises means for casting on the working zone a substantially rectangular hot spot required for lighting the operative site.</p> |
