LAMPE D'ECLAIRAGE CHIRURGICAL AVEC MOYEN AUTOMATIQUE DE REGLAGE DE LA CONCENTRATION DES RAYONS LUMINEUX SUR LE CHAMP OPERATOIRE.

摘要

The surgical lamp comprises at least one reflector (4) and at least one light source (3) which can be moved with respect to the reflector by the means for automatic adjustment of the concentration of the light rays on the operating field. The direction of movement of the light source in the reflector (4) is a function of the result of the comparison by the means (14) of the current algebraic value of the value of the measurement of the light intensity of the light reflected by the operating field with that of the previously performed measurement. The means (10) for measuring the intensity normally comprises a light-sensitive member (11) housed in the handle (5), following the touching of which an adjustment cycle is carried out, during which several light intensity measurements and displacements of the light source (3) are performed in conjunction with the displacement of the light source (3) in order to reach the optimum concentration.
