Abstract

L’invention concerne une source lumineuse matricielle ayant une pluralité de sources lumineuses élémentaires à élément semi-conducteur électroluminescent et un substrat commun en contact avec un circuit intégré. Le circuit intégré est configuré de manière à retarder d’une durée prédéterminée l’allumage des sources élémentaires suite à la réception d’une commande d’allumage. (Fig. 1)
