Le dispositif d'éclairage comprend : une source de lumière ; un élément guide de lumière qui guide la lumière émise par la source de lumière en dessous du plafond ; et un corps de boîtier allongé qui renferme la source de lumière et l'élément guide de lumière. L'élément guide de lumière comprend : une surface d'entrée de lumière qui est allongée et qui est disposée à une surface d'extrémité dans le sens de la longueur ; et une surface émettrice de lumière qui émet de la lumière d'éclairage au niveau d'une surface latérale dans le sens de la longueur. La source de lumière est disposée en face de la surface d'entrée de l'élément guide de lumière. Des éléments de plafond adjacents comportent des première et seconde pièces de fixation qui dépassent chacune vers l'arrière du plafond depuis deux bords latéraux se faisant face. Le dispositif d'éclairage est maintenu de manière à ne pas dépasser de la surface du plafond entre les première et seconde pièces de fixation se faisant face d'éléments de plafond adjacents, et est fixé aux éléments de plafond adjacents par un ancrage qui pénètre successivement dans la première pièce de fixation, le corps de boîtier et la seconde pièce de fixation dans cet ordre en une position située au moins au-dessus de l'élément guide de lumière.
