Description

STEEL FIBER FOR INCREASING A NEGATIVE ION, NON-OZONE, AND NON-NOx TYPE NEGATIVE ION LAMP USING THE STEEL FIBER

TECHNICAL FIELD The present invention relates to a steel fiber, attached to a charge tube of a high voltage generator for emitting anions, for enhancing air purification efficiency by increasing anions emitted when charged, and an anion lamp for purifying indoor air using the same, which doesn't generate ozone and NOx. NOx

BACKGROUND ART Conventional charge type anion generator generates anions by inducing charge transfer by means of electric current and ground, wherein copperplate and aluminum-plate are arranged opposite to each other. Even the conventional anion generator emits anions helpful to the air purification; it has a serious problem that also generates harmful components, such as nitrogen oxide NOx and ozone, which threaten the human body and environment. The copperplate and aluminum-plate ride with charge flow up to crystal grains of nonferrous metal according to the charge transfer due to a high voltage. Here, when corpuscular crystal grains diffuse to the atmosphere, the copperplate and aluminum-plate cause toxic corrosion and deadly poisons due to the reaction with moisture. To overcome the harmful effects described above, platinum or silver is coated on the copperplate and aluminum-plate; however, the harmful materials are not removed completely, more or less than the copperplate and aluminum-plate not coated with platinum or silver. As one of the methods proposed for settling the harmfulness of the above- described copperplate-aluminum-plate anion generator, a study devising to increase the anion emission amount by attaching a steel fiber to a charge tube has been disclosed. However, the anion generator using the charge tube having the steel fiber also generates NOx and ozone of small quantities when charged, which doesn't meet with the purpose to maximize the indoor air purification efficiency. Another method for increasing the anion generation amount is depicted in Fig. 1 , wherein positive and negative output ends of a high voltage generator (a) are connected with a light metal ion transformer (b), which has a large external size due to the volume and is insufficient to the indoor air purification since the anion emission is not continuous. Meanwhile, the indoor air of residential space, study space, or work space, etc. contains minute dust, mildew or bacteria that cause various diseases. For the purpose of purifying the indoor air contaminated, there have been disclosed Korean Utility Model Publication No. 95-35662 that uses an illumination lamp; and Japanese Patent Publication No. 6-178821 , Korean Patent Publication No. 97- 8480, Korean Patent Publication No. 97-6047, 2002-78792, Korean Utility Model No. 265693, and Korean Patent No. 384465, related to illumination lamps having anion generating means. The anion generating means disclosed by the above-identified prior arts emit rectilinear anions by a high voltage discharged when applying an electric current, wherein a discharge pin is arranged in the middle of the charge tube. The rectilinear anions vanish within several seconds and the number of anions is no more than 1 million/cc at intervals of 50 cm, which are incapable of purifying the indoor air contaminated sufficiently. Besides, it is inevitable to arrange terminals connected to a bulb and terminals coupled to the high voltage generator adjacent to each other in view of the internal structure of PCB circuitry, wherein a three-wavelength circuit, is arranged passing through a boosting circuit on a printed circuit board PCB for a three-wavelength lamp. When both terminals are arranged adjacent to each other, it may cause sparks between both terminals when charged. The spark is the main reason to generate harmful ozone and NOx, and causes the transformer to overheat, which may destroy electrical elements such as transistor by the heat, thus impairing the lamp functions or further causing the lamp malfunction. In view of this point, there has been an attempt to prevent the sparks by establishing protection perforations on the margin of PCB where both terminals are positioned; however, it cannot clear well the harmful effects described above.

DISCLOSURE OF THE INVENTION Accordingly, an object of the present invention is to provide a steel fiber, attached to a charge tube of a high voltage generator for emitting anions, for enhancing air purification efficiency by increasing anions emitted when charged. Another object of the present invention is to provide an ozoneless/NOxless anion lamp using the steel fiber, which can purify indoor air efficiently. Still another object of the present invention is to provide an ozoneless/NOxless anion lamp using the steel fiber, which can deodorize indoor volatile organic solvents. To accomplish the first object of the present invention, there is provided a coral calcium carbonate coated steel fiber, made by vacuum evaporation method with ultrapure nano-coral calcium carbonate, which increases the anion emission amount sharply when the calcium carbonate is touched with moisture according to charge transfer made when charged, and when an external force such as vibratory force or frictional force is added. To accomplish the second object of the present invention, there is provided an anion lamp that emits abundant anions and doesn't generate ozone and NOx to purify indoor air by applying the high voltage generator having the steel fiber, wherein an electrode, a high voltage module divided from PCB and the high voltage generator are connected directly with each other by means of wirings, separately from the PCB, to prevent sparks and overheat of transformer due to electrical interference between a lamp terminal of the PCB and a terminal of the high voltage generator, thus protecting functions of the lamp. To accomplish the third object of the present invention, there is provided an anion three-wavelength lamp described in the second object of the invention, wherein low-temperature catalyst is coated on exterior(s) of upper cap and/or lower cap to deodorize volatile organic solvents.

BRIEF DESCRIPTION OF THE DRAWINGS Further objects and advantages of the invention can be more fully understood from the following detailed description taken in conjunction with the accompanying drawings in which: Fig. 1 is a conceptual view showing a conventional anion generator; Fig. 2 is an enlarged view of a thread of a steel fiber in accordance with the present invention; Fig. 3 is a sectional-cut front view of an anion lamp having a high voltage generator using the steel fiber; Fig. 4 is a plane view of a lower cap; and Fig. 5 is a wiring diagram schematic showing how the high voltage generator, an electrode and PCB are arranged.

BEST MODE FOR CARRYING OUT THE INVENTION In Fig. 2, a thread 1a, which is a major element of the steel fiber together with a metal filament, is coated with coral calcium carbonate 2. The thread 1a of the steel fiber includes a carbon filament, carbon fiber, twisted thread coated with conductive metal powders, etc. The thread 1a of the steel fiber coated with coral calcium carbonate 2 is well connected with a charge tube of a high voltage generator for emitting anions and changes the charge transfer, related directly to the anion diffusion, from the conventional rectilinear waveform having a short life and weak diffusiveness to Brownian motion of non-linear waveform, thus emitting and diffusing abundant anions. Minute-porous inorganic coral is formed with ultrapure natural calcium carbonate. Furthermore, the coral emits ultrapure natural anions, a valuable natural resource that exceeds 50% among the oxygen existing on earth. When the ultrapure calcium carbonate extracted from the coral is mixed with water and an external force such as friction, vibration, pressure, etc. is added, it is dissociated into calcium ions and carbonic acid ions. When carbonic acid ions react against water molecule, bicarbonate and hydroxide ions are generated. Here, the hydroxide ions are the anions. CaCO3 + External Force (frictional force, vibratory force, pressure, shock)

Ca²⁺ CO3^2" H₂O (moisture) HCO3^2- OH^' Anion Anions are classified into small ions, intermediate ions, large ions and atmospheric ions by their radius or mobility. Small ions including OH^", generated from efflorescence hermatypic coral, are helpful ions to the human body. Intermediate ions, large ions and atmospheric ions are abundantly included in contaminated air such as exhaust gas or smoke. The radiuses of such ions are as follows: small ions 0.0006/ffli, intermediate ions 0.001 ~0.0925μm, large ions 0.025 m and atmospheric ions 0.025-0.055 m. Fine-powdered nano-coral calcium carbonate increases the anion emission amount sharply and is easy to be coated by vacuum evaporation method since it has a large surface area. Accordingly, the present invention applies the nano-coral calcium carbonate 2. Inorganic coral calcium carbonate 2 having different properties from the thread 1a is hard to be coated uniformly and has a low coating intensity, thus causing unexpected desquamation and functional deterioration. In view of this matter, it is desired to adopt the vacuum evaporation method when coating the thread 1 a with the coral calcium carbonate 2 since it assures a high coating intensity and a uniform coating effect. Next, referring to Figs. 3 to 5, description will be made hereinafter with regard to a three-wavelength lamp 20 having a high voltage generator 10 using the steel fiber 1. An upper cap 21 including an electrode 22 and PCB for three- wavelength 23 is connected with a lower cap 25 having the high voltage generator 10, coupled with the steel fiber 1 , and a plurality of bulbs 24. An uncoated external end of the steel fiber 1 is exposed externally through a fiber perforation 26 provided on the wall of the lower cap 25. When applying an electric current to the three-wavelength lamp 20 and, at the same time, when the high voltage generator 10 is charge accordingly, the coral calcium carbonate 2 is touched with moisture according to charge transfer. Then, the coral calcium carbonate 2 emits small ions OH^" helpful to the human body when an external force such as vibratory force, frictional force, etc. is added, thus fulfilling the function of air purification. Here, the number of anions measured in front of the external end amounts to 1.5 millions/cc at intervals of 1 m considered as a long distance. It is a distinguished result compared with the conventional anion lamp, from which emitted anions vanish at the same intervals measured. Besides, it is found that the number of anions measured nearly reaches 2-3 millions/cc, much more than the conventional one. In addition, it assures an abundant anion emission that amounts to 0.8 million/cc at intervals of 50cm for example, even when the anion lamp is covered with dust due to a long period use. Besides, the anions emitted from the steel fiber 1 of the anion lamp have a powerful function that purifies contaminated indoor air as same with the ion cluster. A high voltage module 27 divided from PCB 23 is established in the lower cap 25 and, as shown in Fig. 5, an inside wiring 28 for the high voltage module 27 is coupled with the electrode 22 and outside wirings 29 are connected with a charge tube 11 and a discharge pin 12, respectively, thus supplying a portion of electric power input through the electrode 22 directly to the high voltage generator 10, not passing through PCB 23 that is exclusively diverted to the three- wavelength circuit. When the input electric power is forwarded directly to the high voltage generator 10, not passing through PCB23 having the three-wavelength circuit, the possibilities that cause the transformer of the three-wavelength circuit to overheat and generate sparks are remarkably reduced relatively. Accordingly, it doesn't incur destruction of electric elements of PCB 23 and generation of ozone and NOx. As a result, pure anions are emitted to purity corrupted indoor air efficiently. Low-temperature catalyst is coated on the exterior(s) of the upper cap 21 and/or lower cap 25. The low-temperature catalyst has a function of neutralizing and deodorizing volatile organic solvents, considered as one of the indoor air contamination causes, within the common ray of light even at normal temperature, differently from photocatalyst responding only at high temperature. Like this, when coating the cap(s) with the low-temperature catalyst, it is well matched with the air purification operation of the anions, thus providing a more exhilarating indoor atmosphere.

INDUSTRIAL APPLICABILITY As described in detail above, the present invention provides a steel fiber, of which a thread, connected with a charge tube of the high voltage generator for emitting anions, is coated with nano-coral calcium carbonate by vacuum evaporation method. When applying the steel fiber to the high voltage generator for emitting anions in accordance with the present invention, the charge transfer is promoted when charged, thus increasing the emission amount of pure anions (small ions) is sharply and assuring the continuous emission of anions, not applying any separate ion converters. Besides, the anion lamp having the high voltage generator using the steel fiber doesn't generate ozone and NOx since the electric current forwarded to the high voltage generator is not passing through PCB for three-wavelength circuit. In addition, the low-temperature catalyst coated on the exterior(s) of the upper cap and/or lower cap is much helpful to the air purification operation since it can deodorizes volatile organic solvents generated from wall-paper adhesive agents, etc.
