Abstract

L'invention, qui concerne un dispositif d'éclairage indirect pouvant être réglé de façon à orienter une source de lumière vers des surfaces adjacentes, concerne également des moyens de montage. Le dispositif comprend un bras support réglable, un corps de luminaire, et une source de lumière, le corps de luminaire étant mécaniquement couplé au bras support réglable, fixant ainsi le dispositif d'éclairage à la surface adjacente. La source de lumière, qui est supportée par le corps de luminaire de façon à être orientée vers l'arrière en direction de la surface de montage, peut être dirigée au moyen du bras support réglable permettant un mouvement de pivotement du corps de luminaire autour d'au moins un axe.
