Abstract

Un dispositif électroluminescent omnidirectif comprend un substrat (11) et une pluralité de sources lumineuses à DEL (12) disposées sur le substrat (11). Un abat-jour guidant la lumière (13) permettant de réfracter et de réfléchir les rayons lumineux émis par les sources lumineuses à DEL (12) est disposé au-dessus du substrat (11). Les rayons lumineux émis par les sources lumineuses à DEL (12) sont réfractés et réfléchis par l'abat-jour guidant la lumière (13), de sorte que les rayons lumineux rayonnent tout autour, et la portée d'éclairage des sources lumineuses à DEL (12) est par conséquent considérablement augmentée.
