Abstract

L'invention porte sur un élément miroir à diode électroluminescente organique (DELO) (10, 10', 10") comprenant une source de lumière DELO (20), un interrupteur (30) pour allumer ou éteindre la source de lumière DELO, une source de lumière infrarouge (IR) (40) émettant de la lumière IR sensiblement perpendiculaire à la surface d'émission de lumière de la source de lumière DELO et un détecteur de lumière IR (50) détectant de la lumière IR sensiblement perpendiculaire à la surface d'émission de lumière de la source de lumière DELO. Le détecteur de lumière IR, en réponse à un signal réfléchi détecté de la source de lumière IR, actionne l'interrupteur, et l'angle d'acceptation du détecteur de lumière IR dans une direction normale est limité, de sorte que seuls des objets se trouvant sensiblement en face de l'élément miroir DELO (10, 10', 10") à portée de détection soient détectés.
