Le module de source de lumière comprend un premier élément électroluminescent et une partie boîtier recouvrant le premier élément électroluminescent. La partie boîtier comprend un premier moyen d'éclairage supplémentaire, un deuxième moyen d'éclairage supplémentaire et un troisième moyen d'éclairage supplémentaire. La lumière émise par les illuminants est mélangée en une lumière blanche chaude servant de lumière émise par le module de source de lumière. Le module de source de lumière selon la présente invention fournit une source de lumière blanche chaude à DEL (3000 K) ayant une efficacité lumineuse élevée, une faible valeur CS, et un indice de rendu de couleur élevé en même temps en régulant une proportion d'énergie de luminescence dans la plage de longueurs d'onde de 495-580 nm ayant la plus grande influence sur les valeurs CS dans l'énergie de luminescence totale. La lumière a de faibles valeurs CS et est particulièrement appropriée à des fins de loisirs, et fournit un environnement d'éclairage de relaxation.
