Abstract

L'invention concerne une lampe (1), en particulier une lampe à suspension, constituée d'un corps (2) présentant, d'un côté, une première zone d'émission lumineuse (4) dotée d'un premier élément (9) influant sur la lumière et, de l'autre côté, une seconde zone d'émission lumineuse (21) dotée d'un second élément (22) influant sur la lumière pour un éclairage indirect. L'objectif de cette invention est d'améliorer l'éclairage indirect de la lampe. A cet effet, le second élément (22) influant sur la lumière peut être réglé dans au moins deux positions différentes (S1, S2, S3).
