Abstract:
Submersible light generator with an impermeability protection for glass or plastic optic fibers, wherein:a) said submersible light generator comprises a plurality of impervious modules, said impervious modules being separated and thermally insulated from one another, said modules being further connected to one another so as to be impervious to gas and liquid, b) wherein the modules of the light generator comprise: at least one impervious lamp module, comprising at least one lamp sending at least one light beam over at least one focusing optic system, the lamp module being connected to an electric energy source so as to be impervious to gas and liquids, at least one impervious light transfer module which receives the light beam leaving the lamp module, wherein one of the lateral sides of the light transfer module is in proximity with the lateral sides of the lamp module, the passage of the light beam taking place across two sealed windows made of an optically transparent material, positioned opposite each other, respectively in said lateral sides of the lamp and light transfer modules, the light transfer module having on another of its sides a connector for a set of optic fibers; c) between the lateral sides of the lamp and light transfer modules facing each other, outside the zone provided for the passage of the light beam which is delimited by the two sealed windows, means are provided to ensure the impermeability of the lamp and light transfer modules with the external environment, which take into account the thermal expansion and the thermal shrinkage of materials, and thermal insulation means positioned between these modules; d) the other sides of the lamp and light transfer modules are made of a heat conductor material and, when said sides constitute part of the external sheath of the light generator, said other sides are configured to have a thermal exchange external surface in contact with the external environment and an internal surface in contact with the internal atmosphere of the modules allowing heat transfer towards the outer surface.
