Procédé de fabrication d'une luminaire allongée horizontalement (1), dans lequel, dans une première étape du procédé, un premier élément de boîtier (21) est relié en position fixe à un premier élément de support (23) pour créer un premier élément de luminaire (2), et un deuxième élément de boîtier (31) est relié au deuxième élément de support (33) pour créer un deuxième élément de luminaire (3), dans lequel les éléments de boîtier (21, 31) des éléments de luminaire (2, 3) enfermant les éléments de support (23, 33) des éléments de luminaire respectifs (2, 3) perpendiculairement à la direction horizontale (X) au moins par sections, dans lequel, dans une deuxième étape du procédé, les deux éléments de luminaire (2, 3) sont reliés l'un à l'autre à leurs extrémités horizontales par l'intermédiaire de leurs éléments de support (23, 33) de manière à créer une luminaire (1) dont le support est formé par les éléments de support (22, 33) dans l'extension horizontal de deux éléments de luminaire (2, 3) et présente un évidement (100) entre les deux éléments de boîtier (21, 31) qui s'étend d'un côté supérieur (11) de la luminaire (1) à un côté inférieur (12) de la luminaire (1), dans lequel des sources lumineuses (7) sont disposées sur le support et/ou sur le boîtier et sont enfermées par sections par le boîtier perpendiculairement à la direction horizontale, cet enfermement étant interrompu par des ouvertures de sortie de la lumière prévues dans le boîtier, dans lequel le premier élément de luminaire (2) forme une section indirecte (2) pour rayonner de la lumière depuis le côté supérieur (11) de la luminaire (1) pour fournir un éclairage indirect de la pièce et dans lequel le second élément de luminaire (3) forme une section directe (3) pour rayonner de la lumière depuis un côté inférieur (12) de la luminaire (1) verticalement opposé au côté supérieur (11) pour fournir un éclairage direct de la pièce et dans lequel l'évidement (100) sur le côté inférieur mène dans l'une des ouvertures de sortie de lumière prévues dans la section directe et sur le côté supérieur dans l'une des ouvertures de sortie de lumière prévues dans la section indirecte, en particulier les éléments de lampe (2, 3) étant reliés entre eux en télescopant leurs parties de support horizontalement l'une dans l'autre au-delà d'une partie de chevauchement.
  18. Procédé selon la revendication 17,
    caractérisé en ce que
    pendant la première étape du procédé, un premier élément optique (22) est inséré horizontalement dans le premier élément de boîtier (21) pour créer le premier élément de luminaire (2) et qu'après l'achèvement de la deuxième étape du procédé, un deuxième élément optique (32) est inséré horizontalement dans le deuxième élément de boîtier (31), en partant du côté du deuxième élément de luminaire (3) détourné du premier élément de luminaire (2).
