Abstract
The invention relates to a tube emitting electromagnetic radiation which is made of glass or transparent non-fluorescent quartz, and has an elongated boring able to house a radiation-emitting filament or bundle. The boring has a substantially square or rectangular cross-section, at least two opposite sides of which form dioptric convex surfaces shaped to alter the direction of the radiation emitted by the filament or axis of the bundle so as to render them parallel or substantially parallel in the solid transparent glass medium.
Claims30
A tube for emitting electromagnetic radiation, made of a transparent non-fluorescent material, in particular a glass-based or quart-based material, and having a straight structure drilled from end to end by a bore elongate around an axis, confining a housing designed to contain a radiation-emitting filament or plasma bundle, characterized in that the bore is of appreciably square or rectangular shaped cross section having four sides of which are in the shape of convex curves, said sides forming dioptric surfaces arranged to modify the direction of the rays emitted from the filament or from the axis of the emitting bundle to make them parallel or appreciably parallel in the transparent solid medium of the glass.
A process for application of radiation to a product in sheet form or disposed on a flat or curved surface, characterized in that the product is irradiated with a radiation-emitting element presenting a very small cylindrical or appreciably cylindrical cross section with a radius centered in the bore of a straight glass tube, elongate around an axis, said bore being of appreciably square or rectangular shaped cross section having four opposite sides of which are in the form of convex curves, said sides forming dioptric surfaces arranged to modify the direction of the rays emitted from the axis of the bore to make them parallel or appreciably parallel in the transparent solid medium of the glass, before being diverted to the product by reflecting surfaces.
