Des diodes électroluminescentes (110, 111, 112, 120, 121, 122) sont agencées sur les parties de recouvrement de manière à faire face à la partie de fond. La partie de fond est conçue pour diffuser la lumière de sorte qu'une lumière homogène en termes de luminosité et de couleur soit émise par une ouverture de sortie de lumière. Une pluralité d'éléments de lampe peuvent être assemblés les uns aux autres dans le sens longitudinal.
