Abstract:
A device applicable to mercury gas discharge and fluorescent lamps of the type which generate ultra violet radiation (253.7 nm to 380 nm) to interact with fluorescent particles covering an internal wall of the lamp to produce visible light, said device comprising:an external structure of rigid, transparent, inorganic and dielectric material (A), with shape and dimensions conforming to a lamp to be used, said structure (A) being open to permit insertion of a lamp;within structure (A), a reflector (D) comprising a metallic reflective surface insulated against electricity along its length by a transparent, dielectric, organic material, the reflector (D) covering up to 50% of the internal surface of the inside wall of structure (A); andend cap means (B) of semi-rigid dielectric material to close structure (A) and holds a lamp within structure (A) and spaced from reflector (D) a distance less than the optical focus with reference to the lamp;whereby, the device, when surrounding a working lamp, will cause the spontaneous formation of an electric field (E) between the device and the lamp, the electric field (E) being maintained by the ultraviolet radiation (253.7 nm to 380 nm) dispersed through the wall of the lamp, until reaching a saturation level that hinders the further dispersion of the ultra violet radiation, which in turn induces a greater flow and discharge of the ultraviolet radiation onto the fluorescent particles that cover the internal wall of the lamp, resulting in an increase in the emission of visible light and an improvement in Lumens generated per Watt.
