Sur au moins une partie de cette surface intérieure se trouve une couche génératrice de rayons infrarouges en contact thermo-conducteur avec un récipient (1, 10) conçu pour contenir ou faire circuler le fluide chauffé. Un objet (6, 12) présent à l'intérieur de ladite zone est conçu pour être chauffé par le rayonnement émanant de ladite couche active et par le rayonnement réfléchi provenant de la surface intérieure. Dans un mode de réalisation, ladite surface intérieure est constituée par un panneau émetteur de rayons infra-rouges et un miroir parabolique lui faisant face. Ledit objet est un tube disposé le long de la ligne focale dudit miroir. L'invention concerne également un dispositif d'éclairage fait pour récupérer la chaleur créée par les lampes.
