Abstract

L'invention concerne un dispositif électroluminescent (1) qui comprend une pluralité de sources de lumière à DEL, la pluralité de sources de lumière à DEL comprenant un premier groupe de DEL (A) émettant, lors de l'utilisation, une lumière ayant un premier spectre de couleur, un deuxième groupe de DEL (B) émettant, lors de l'utilisation, une lumière ayant un deuxième spectre de couleur et un troisième groupe de DEL (C) émettant, lors de l'utilisation, une lumière ayant un troisième spectre de couleur, le premier spectre de couleur, le deuxième spectre de couleur et le troisième spectre de couleur étant différents l'un de l'autre, la pluralité de sources de lumière à DEL étant agencées en un réseau (2), dans lequel réseau les DEL de chacun du premier groupe de DEL, du deuxième groupe de DEL et du troisième groupe de DEL sont agencées sur deux cercles concentriques ou plus (51, 52, 53), les centres (500) du ou des cercles concentriques coïncidant avec un centre (6) dudit réseau (2), le centre (6) dudit réseau (2) étant exempt de DEL, au moins une DEL de chacun du premier groupe de DEL, du deuxième groupe de DEL et du troisième groupe de DEL étant agencée sur chacun des deux cercles concentriques ou plus (51, 52, 53), et les DEL de chacun du premier groupe de DEL, du deuxième groupe de DEL et du troisième groupe de DEL étant agencées sur au moins deux lignes incurvées s'étendant à partir du cercle le plus à l'intérieur (53) des deux cercles concentriques ou plus vers le cercle le plus à l'extérieur (51) des deux cercles concentriques ou plus.
