Abstract

L'invention concerne un système pour récupérer l'énergie dégagée par des sources lumineuses sans électrodes, notamment en provenance de lampes sphériques rotatives et refroidies contenant de faibles quantités d'argon et de soufre ou de sélénium et disposées dans un champ électromagnétique d'ondes micrométriques focalisées par une cage en fil métallique, dégageant ainsi une lumière aveuglante, froide et d'un spectre analogue au soleil, dans un tube conducteur de lumière relativement long qui présente sur sa face intérieure une couche réfléchissante transparente et guide la lumière, par des orifices de sortie de lumière, sur la surface à éclairer. Ce tube conducteur de lumière est coaxialement entouré par un deuxième tube extérieur, des éléments de blindage en plastique étant insérés entre le tube conducteur de lumière et le tube extérieur. Pour récupérer l'énergie, ces éléments de blindage disposent, sur leur surface incurvée située en regard du tube conducteur de lumière, d'un revêtement photovoltaïque transformant en courant continu la quantité de lumière pénétrant dans la couche réfléchissante transparente, ou bien à la place du tube extérieur et des éléments de blindage, un boîtier muni de ce revêtement et d'orifices de sortie de lumière entoure au moins partiellement le tube conducteur de lumière.
