Abstract
This invention is essentially a device that, applied to a functioning lamp or fluorescent tube, creates an electric field, or ionized cavity (E), around the lamp or tube and thus impedes the additional energy dispersion that such lamps or fluorescent tubes normally discharge and lose in the form of ultraviolet radiation. From this follows a greater efficiency in the conversion of ultraviolet radiation into visible light, thus making this device an important tool for the saving of energy.
Claims6
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);
- and
- end 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.

- internally of structure (A) a dielectric, flexible sheet (C) or organic crystal transparent material which holds in place the reflector (D) placed against the internal wall of the external structure (A) along the entire internal surface;
- and
- end cap means (B) of semi-rigid dielectric material to close structure (A) and hold 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 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.
Increasing the efficiency of energy utilization by mercury arc vapor and fluorescent lamps, comprising:
- providing a mercury arc vapor or fluorescent lamp of the type which generate ultra violet radiation (253.7 nm to 380 nm) that interacts with fluorescent particles covering an internal wall of the lamp to produce visible light;
- placing around said lamp an external structure of rigid, transparent, inorganic and dielectric material (A), with shape and dimensions conforming to the lamp, said structure (A) being open to permit insertion of the lamp;
- providing 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);
- and
- providing end cap means (B) of semi-rigid dielectric material to close structure (A) and hold the lamp within structure (A) and spaced from reflector (D) a distance less than the optical focus with reference to the lamp;
- whereby, an electric field (E) is formed between the device and the lamp, the electric field (E) being maintained by ultraviolet radiation dispersed through the wall of the lamp, until reaching a saturation level that hinders further dispersion of ultra violet radiation, which in turn induces a greater flow and discharge of ultraviolet radiation onto the fluorescent particles that cover the internal wall of the lamp and results in increased emission of visible light.
