FIXTURES

Technical Field

[1] The present invention relates to a negative ion generator and a purifying apparatus for indoor air using same, in particular, to a negative ion generator which is without any production of harmful materials such as ozone, nitrogen oxide, and the like, and to a purifying apparatus for indoor air combined with lighting fixtures, which can perform lighting and purifying the contaminated indoor air at the same time by installing the negative ion generator to the lighting.

Background Art

[2] In general, it has been known that the negative ion acts to neutralize and precipitate several gaseous contaminating materials such as nitrogen oxide, sulfur oxide, carbonate hydrogen, carbon mono oxide, carbon dioxide, and the like, and VOC materials such as formaldehyde, toluene, and the like, and cigarette smoke, and the like to thereby purify the air and remove bacteria, and stink, and the like. Further, it has been known that it neutralizes several harmful electronic waves, and helps to prevent and treat several chronic diseases such as neuralgia, asthma, sleeplessness, and the like, and activate the human body to recover from the fatigue, and helps to release the stress and increase the efficiency of study. The negative ion generator has been widely used for purifying the indoor air owing to such advantages.

[3] Most of the conventional negative ion generators can be divided into a plasma type and a pin type, however, the pin type (i.e., a needle point type) negative ion generator, which is excellent in efficiency of producing the negative ion, has been used largely. The pin type negative ion generator was constructed that a plurality of metallic discharge pins were secured to a metallic plate, and the negative ion was produced by applying a negative high voltage to the pins to ionize the air.

[4] However, the pin type negative ion generator has a problem that the ozone (O ) and the nitrogen oxide have been produced concurrently at the time of producing the negative ion. While the ozone is excellent in sterilizing and deodorizing with strong oxidizing force, it is changed into horrible poisonous materials damaging the cells of the lungs or the bronchial tube, if it is contacted with the human skin or enters into the inspiration organs. As a result, several countries of the world regulate the permissible amount of the ozone to utilize the advantages of sterilization and deodorization.

[5] In this regard, although the ozone is within the permissible amount, if it is used in

the closed space, it can affect the human body seriously because of the deficiency of the oxygen and the moistures, and the like. Therefore, it is desirable to prevent the production of the ozone and the nitrogen oxide and the like to secure the safety.

[6] Japanese patent application laid open No. Hei 11-290716 discloses a conventional negative ion generator, which does not produce the ozone or the nitrogen oxide. The conventional negative ion generator was constructed that a small box was made by cutting a mid portion of a coated wire between a high voltage generating portion and a discharge pin, and a porous natural light stone was inserted into the box to ionize the electric energy and discharge with long discharge pins having a size of finger length to produce the negative ions. However, while it is an improved technology, problems were occurred that the function of producing the negative ions was decreased due to the contamination of the discharge pins, the construction of the negative ion generator was complex, and it was difficult to apply to such products as requiring the compact negative ion generator, or the lighting fixtures because of the difficulty of making it compact.

[7] Meanwhile, the negative ion generator is employed in the purifying apparatus for indoor air in spite of the problems described above, and it has been known that the negative ion generator was also applied to the lighting fixtures. However, the conventional negative ion generators described above still cannot settle the problem that the ozone and the nitrogen oxide were produced concurrently with the production of the negative ions.

[8] Further, according to any one of the conventional stand type negative ion generator and the lighting fixtures using the negative ion to purify the indoor air, a problem was occurred that the production efficiency of the negative ion was decreased because the contaminating materials precipitated at the time of ionizing the air were attached to the discharge pins. Disclosure of Invention Technical Problem

[9] As described above, according to the conventional negative ion generators, problems were occurred and still remained unsettled that harmful materials such as the ozone and the nitrogen oxide and the like were incidentally produced at the time of producing the negative ions, the ionizing degree of the discharge electrodes was decreased due to contamination of the discharge electrodes, and the emitting amount was decreased because the metallic wire connected from the high voltage generating portion to the discharge electrode was deteriorated and vaporized by means of the high voltage emitting to thereby reduce the current density.

[10] Therefore, the present invention has been made to solve the problems occurring in

the conventional arts, and the object of the present invention is to provide a negative ion generator, in which the negative ions are produced without the production of the ozone and/or the nitrogen oxide by combining several materials and devices. Technical Solution

[11] More concretely, in the present invention, the high voltage generating portion is constructed to convert the 220V AC into 3 - 12 DC and produce 2500V pulse high voltage according to the use condition, and fine powders or solution made by mixing tormalin, and mineral materials producing a plurality of negative ion are coated on a conductive metallic wire connected from the high voltage generating portion to the discharge pins and an inner diameter wall of the covering made of silicone rubber enclosing the conductive metallic wire, and a nano titanium dioxide or a compound solution made of nano titanium phosphate are coated on the discharge pins. The present invention is to provide negative ion generator, in which a large volume of negative ions can be emitted to a long distance without producing any harmful materials such as the ozone and the nitrogen oxide and the like by combining such materials and the devices, the remaining time of the air is longer than that of the prior art, and a large volume of the cluster negative ions are produced continuously without reducing the production amount of the negative ions due to the contamination of the discharge pins.

[12] Further, the present invention is to provide a purifying apparatus for indoor air used for a lighting, which is constructed by mounting the negative ion generator to the lighting such as an FPL, an FLR, an FCL and the like, and performs the function of air purifying by means of the photo catalytic reaction and the function of producing the negative ion by coating the photo catalytic material having excellent effect in comparison with the conventional art.

[13] The photo catalyst is to decompose the contaminant and remove the stink and the like by radiating an ultra violet ray on the oxidized metallic semiconductor, and a titanium dioxide is widely used as the representative photo catalyst. If the ultra violet ray having 300 ~ 400 D band wavelength, which is radiated from the sun light or the fluorescent light, is radiated on the surface of a substance having the titanium dioxide coated thereon, electrons and vacancies are formed as the electrons are migrated into a conducting zone.

[14] It has been known that, as the electron and the vacancy have very strong oxidizing force and reduction force, they react with water vapor (H2O) or oxygen (O2), and the like in the air to produce a strong OH radical, an H radical, and the like to become a state as they are heated to 36,000°C to oxidize or decompose almost all of the organic materials and the contaminant materials. It has been known that they purify air by

oxidizing and decomposing the gaseous contaminating materials in the air such as nitrogen oxide, carbonized hydrogen, carbon mono oxide, sulfur oxide, ozone, and the like, and VOC materials such as formaldehyde, toluene, xylene, benzene, radon, and the like, and cigarette smoke, and smells thereof, and the stink such as ammonia and the like. Further, they are known to have excellent effect of sterilizing the harmful bacteria such as a tick for home dust, bacteria, virus, mold, germ, and the like, and have the effect of increasing the greed of a living thing, such as blocking the ultra violet ray from the lighting to protect the visual force and expose to the sun light.

[15] The negative ion generator of the present invention comprises, a negative ion generating unit made of one unit by immersing respective circuit parts of a high voltage generating portion built into a case with ceramic insulator, the high voltage generating portion being operated to convert an input electric power into high voltage for producing the negative ions, a emitting tube for transferring the negative high voltage from the negative ion generating unit to a discharge electrode, and a emitting portion attached to an end of the emitting tube for emitting the negative ions into atmosphere,

[16] wherein the emitting tube is constructed of a plurality of metallic conductive wires with negative ion emitting material coated on them, and a covering with negative ion emitting material coated on the inner wall thereof for insulating the conductive wires from the outside by coating an inner wall thereof with the negative ion producing material, and a discharge electrode of the emitting portion is coated with TiO2.

[17] Also, in the present invention, the negative ion emitting material is any one selected from the tormalin solution, a mineral material solution made by mixing any one or at least two mineral materials emitting the negative ion and far infrared ray such as kiyoseki, natural ore, a horoonhelts, a meteoric stone, elvan, emery medicine stone, a rigid mica, a black mica, and dragon king stone, and a composite solution made by mixing the tormalin solution and the mineral material solution.

[18] Further, the emitting tube is characterized in that it is of a multiple line structure made by coating several metallic conductive wires on the covering, and an aluminium alloy material having high conductivity and high heat resistant property is used for the conductive wire.

[19] Also, the covering is made of silicone rubber material, with the inner wall thereof coated with any one or at least two materials selected from mineral materials such as a tormalin, kiyoseki and the like emitting the far infrared ray and the negative ion, and ultra fine materials such as a weak charcoal, and the like.

[20] Further, the discharging portion is constructed of any one structure selected from a radiating pin structure formed with a plurality of pins in the radial direction, a single needle structure, and a bundle structure made of a plurality of thin conductive wires, so

that it can radiate the negative ions. That is, it can be used as alloy needle made of several metals and coated with the nano TiO solution, or alloys made of stainless steel, titanium, aluminium, copper, and the like are made into metal threads having a size of 2 ~ 5 D, and a plurality of metal threads are bound into a bundle shape coated with the nano TiO solution and are attached to the metallic conductive wires of the emitting tube.

[21] Moreover, emitting portion can be constructed by coating a nano titanium oxide reacting with the visible light ray or the ultra violet ray, or coating a titanium oxide compound reacting with the air or water.

[22] Also, the negative ion emitting portion unit is constructed to be one integral package made by sealing the high voltage producing circuit such as a transformer, a rectifying circuit, a condenser, a high voltage amplifying circuit, and the like with strong insulator ceramics so that it cannot be affected from the outer environment such as high temperature, and the like.

[23] Accordingly, the negative ion generator of the present invention has the advantage that it is possible to prevent the production of the harmful materials such as the ozone and NOx and the like, and the reduction of the emitting efficiency of the negative ions by coverings radiating the negative ions on the conductive wires and coverings of the emitting tube, and the nano TiO solution on the discharge pins.

[24] According to the present invention, there is provided an air purifying apparatus for the lighting comprising the negative ion generator, in which the negative ion generator and a plurality of UVA LEDs are installed to a base panel of the lighting, and photo catalytic materials are coated on a cover glass of the lighting.

[25] Also, the lighting of the present invention is characterized in that a plurality of

UVA LEDs are installed to a base panel of the lighting, and photo catalytic materials are coated on a cover for the lighting to perform the functions of sterilizing and air purifying by means of the photo catalytic action of the visible light ray or the ultra violet ray.

[26] According to the negative ion generator of the present invention, because several circuits are immersed and sealed in a strong insulator at the time of installing the circuits in the negative ion emitting portion unit, and the emitting tube (coating conductive wires) leading to the emitting portion is formed by a silicone rubber material having most excellent insulating property, it is possible to prevent the disorder of the circuits due to the high radiation of the heat at the time of using the lighting, and the function of the emitting tube cannot be affected.

[27] The air purifying apparatus for the lighting of the present invention is provided with the negative ion generator and is coated with the photo catalytic materials. The photo catalyst is excellent to remove the gaseous contaminating materials, bad smells such as

cigarette smokes, and harmful germs. Although the effect of the photo catalyst is excellent depending on the area of the supporting zone and the amount of the light source, the conventional technologies cannot expect the desired effect as the coating area of the TiO and the light source were not sufficient.

[28] In the present invention, glass beads of various shapes having a size of 10 ~ 40 mesh and coated with the nano TiO reacting with the visible light ray or the ultra violet ray are attached to the outer periphery of the cover glass of the lighting by means of transparent binder, or glasses coated with sol or gel are used, which are made of the nano TiO by using the coating technology of forming a silicone oxide film on the surface of the glass. The size and shape of the glass beads can be selected to maximize the action of the photo catalyst.

[29] The glass formed with the glass beads or made by the coating technology has effect four to five times bigger than that of the general glass, because the integration degree is high as is the case of coating the TiO numbers of times the coating of the general glass. The reason of coating the TiO on the outer periphery of the case glass is that while the photo catalyst is required to contact with the air at the time of performing the photo catalytic action through the radiation of the light source, in case of performing the coating on the inner periphery of the glass, desired effect cannot be obtained because the photo catalyst cannot contact with the air smoothly.

[30] The glass can be substituted with the high strength plastic, and can be used with attaching the glass bead coated with the nano TiO for the plastic by means of the transparent binder.

[31] Also, it is possible to prevent the contamination of the above parts by maximizing the supporting zone of the photo catalyst through the coating of the nano TiO on a reflective mirror of the base panel for the lighting, an outer periphery of the stabilizer circuit housing, a bracket of the outer wall in the housing, a lamp case, and an outer periphery of a body, and the like, and incidentally preventing the attachment of the contaminating materials charged at the time of the discharging of the negative ions. The TiO is excellent in preventing the contamination, and has a hydrophile property to prevent the occurrence of the vapor on the lamp at the time of using the lamp coated with the photo catalyst in the bathroom and the like.

[32] The photo catalyst is operated to perform the synergy effect in the purifying of the air by oxidizing and decomposing the contaminating materials precipitated through the emission of the negative ions, and reduce the amount of the contaminating materials, which are positive ions, neutralized and precipitated by the negative ions to thereby produce large volume of the negative ions rapidly and increase the remaining percentage of the negative ions in the air.

[33] As for the light source for the photo catalyst, a plurality of UVA LEDs are arranged

and attached to the main body of the lighting such as the base panel of the lighting and the outer wall of the stabilizer housing in addition to the ultra violet ray or the visible light ray radiated from the fluorescent light, to thereby suffice the deficiency of the ultra violet ray radiated from the fluorescent light. As a result, it is possible to use them as the light source for the photo catalyst and mood lightings at the extinction of the lighting.

[34] The UVA is harmless to the human body, and the TiO is a blocking material for the UVA. Therefore, there is no possibility of the damage due to the UVA because the glass coated with the photo catalyst is positioned under the UVA LEDs almost all of the time. Accordingly, it is possible to obtain more excellent improved effect of the photo catalyst than that of the conventional art as sufficient supporting zone for the photo catalyst and sufficient light source have been secured.

[35] The photo catalyst produces the oxidation and reduction force by reacting with the

UV, and it has been developed to perform photo catalytic action by adding the additives reacting with the visible light ray.

[36] In the conventional art, there were lightings for purifying the air with any one function of emitting the negative ions or performing the photo catalytic action, and there was not any lighting for purifying the air with two functions as is in the present invention.

[37] As the photo catalyst oxidizes and decomposes the fine contaminating materials neutralized and precipitated by means of the negative ions to produce the synergy effect, it is possible to obtain improved effect of purifying the air more excellent than that of the conventional lighting for purifying the air with any one function of emitting the negative ions and performing the photo catalytic action. The conventional art has a problem that it performs the purifying of the air only at the time of the turn on of the lighting, and the function is stopped at the time of the extinction. The indoor air is contaminated by the flow in of the contaminated outside air and the contaminating materials produced in the indoor. In this regard, if the function of purifying the air is not always performed and stopped, it is difficult to consider that the air purifying apparatus is installed. However, according to the present invention, circuits and sensors are installed in the housing of the stabilizer circuit to perform the functions of emitting the negative ions and producing the photo catalytic action after the extinction of the lighting incidentally to thereby perform the air purifying function continuously, and the extinction of the lighting can be performed only by the remocon or the string. That is, switches are separately provided to operate the lighting, the negative ion generator, and the UVA LEDs respectively.

[38] Such technologies have not been disclosed in the conventional art, and are functions more excellently improved than those of the conventional lighting for purifying the air.

Also, following additive functions in addition to the purifying function of the indoor air can be added depending on the usage of the lamps. In this regard, a perfume cartridge can be attached to the lamp to make the purified indoor air pleasant and soft, and the perfume cartridge can be constructed that it is operated to produce the perfume at the radiation of the heat from the lamp, and porous metal sintered body is coated on the bracket of the outer wall of the stabilizer housing, the cylindrical bracket of a stay, the pipe, and the like, and the female nut is made of the porous metal sintered body to refill the perfumes in the porous metal sintered body and use it. According to the emission of the perfumes, it is possible to increase the study capacity and the work efficiency at the time of watching the TV or reading, studying and working, and it is possible to help release of the stress and the recover from the fatigue of the mind and body.

[39] The perfume has been used as assistant treating materials for several diseases from the ancient time, and as called "an aroma therapeutic effect", and it helps to improve the human health by releasing the mind and body of the people, releasing the stress, removing the melancholia, increasing the retentive faculty, sterilization of the air, increasing the antifungal action, treatment of the rhinitis, antiphlogistic action, treatment of the asthma, treatment of the headache, increasing the trichosis action, and increasing the immunity power, and the like.

[40] The aroma is a negative ion having a high volatile property, and it has been known to produce most excellent effect at the time of combining with the positive ions due to the synergy effect. Advantageous Effects

[41] Accordingly, the present invention is economic because the structure is simple to thereby remove the necessity of maintenance and purifying and low cost, and it purifies the air with more improved function in comparison with the conventional air purifying lighting with only one function. Further, it is possible to improve the health and purify the air with the abundant natural negative ions similar to the woods, the photo catalytic function with the sterilizing effect, and the aroma therapeutic effect, and the like.

[49] Hereinafter, the present invention will be explained in detail with reference to the appended drawings below.

[50] FlGs. 1 through 4 are views showing the construction of the negative ion generator according to the present invention. As shown in FlG. 1, the negative ion generator of the present invention comprises a negative ion generating unit 130 made of one unit by immersing respective circuit parts of a high voltage generating portion built into a case with a strong insulator ceramic, the high voltage generating portion being operated to convert an input electric power into high voltage for producing the negative ions, a emitting tube 131 for transferring the negative high voltage from the negative ion generating unit 130 to a discharge pin, and a emitting portion 132 attached to an end of the emitting tube 131 for radiating the negative ions into atmosphere.

[51] As shown in FlG. 2, the emitting tube 131 is constructed of a plurality of conductive wires 11 with a plurality of negative ion emitting materials coated on them, and a covering 12 for insulating the conductive wires from the outside by coating an inner wall thereof with the negative ion producing material, and a discharge pin of the emitting portion 132 is coated with TiO2. Here, the numeral 1 Ia is a coating film made of a tormalin solution or a mineral material solution coated on the conductive wire 11, and the numeral 12 is a coating film made of a tormalin powder or a mineral powder coated on an inner wall of the covering 12.

[52] In the present invention, the tormalin solution of nano or micron unit is used as the negative ion producing material, or mineral material for radiating a far infrared ray and producing the negative ion, which is made by mixing the tormalin solution and one or at least two materials selected from kiyoseki, elvan, emery medicine stone, rigid mica, black mica, and the like is used as the negative ion emitting material.

[53] The conductive wires 11 of the emitting tube 131 the metallic conductive wires are constructed of a multiple line structure, each of the conductive wire is coated with negative ion emitting materials, and is covered by the covering with the negative ion producing materials coated on it, and conductive wires made of an aluminium alloy material having high conductivity and a high heat resistant property are used in the

present embodiment.

[54] Further, silicone rubber is used as the covering 12, and the inner wall of the covering is coated with one or at least two materials selected from the tormalin solution, or the mineral materials such as kiyoseki and the like radiating the far infrared ray and producing the negative ion, or ultra fine material such as weak charcoal, and the like.

[55] Although the discharge pin of the emitting portion 132 is constructed of an alloy composed of several metals, it can be constructed of a plurality of radiating pins as shown in FIG. 1, it can be constructed of a single needle structure as shown in FIG. 3, and it can be used as a bundle of metal threads having a size of 2 ~ 5D made of stainless steel, titanium, aluminium, copper and the like as shown in FIG. 4. In this regard, the emitting portion 132 can be used after spraying and coating the nano TiO solution. Here, the numeral 132a represents for a securing member of the discharge pin (electrode).

[56] FIG. 5 is an exploded perspective view showing the whole structure of an FPL having functions of air purifying and health increasing by applying the technology of the present invention, and FIG. 6 is a cross-sectional view showing the whole structure of the FPL. As shown in the drawings, it is constructed that a base panel 90 is mounted with an electric power portion at the inside, a lamp holder clip 101 is attached to the base panel 90, a stabilizer circuit for the lamp, a negative ion generating unit 130, and a lamp socket 102 are installed in a lower housing 110 for the stabilizer circuit so that the stabilizer circuit and the negative ion generating unit 130 are installed vertically between the both sides of the socket 102, an outer wall of the housing 110 for the stabilizer circuit encircles the housing by means of a bracket 11 made of metallic material, a through-hole is penetrated at the lower of the bracket to communicate with the lower end of the housing 110 for the stabilizer circuit, and then, a small pipe 122 is attached to communicate with the through-hole of the bracket 111 in the outer wall of t he housing at the upper end, and a male thread is formed at the lower portion of the pipe 122 and a female nut 123 is provided for engaging with the male thread.

[57] Here, the negative ion generating unit 130, the emitting tube 131, and the emitting portion 132, which are the principal construction of the present invention, are prepared to constitute the negative ion generator as described in connection with FIG. 1 through FIG. 4. As a result, negative ions are produced without producing the harmful materials such as the ozone and the nitrogen oxide and the like.

[58] Further, a lower cover 120 is constructed of glass formed with a through-hole 122 A so that the metallic pipe 122 can pass through the hole to project to the lower portion.

[59] The emitting tube 131, which is extending downward to the emitting portion 132 of the lower negative ion from the negative ion producing portion unit 130 installed in the

stabilizer circuit housing 110, is inserted into the pipe 122 penetrating the lamp cover 120 to project to the lower portion, and the negative ion emitting portion 132 is drawn to the just lower side of the lamp cover glass with a lamp extinct string 106.

[60] The stabilizer circuit housing 110 and the outer wall bracket 11 are engaged with each other by inserting bolts into engaging holes 121 at both sides of the bracket and engaging holes 121 of the base panel.

[61] The lamp cover 120 (also is denoted as a photo catalyst cover) is made of glass coated with the photo catalyst, and is formed with a plurality of emitting holes 133 penetrating the inner and outer peripheral surfaces, so that the radiating heat of the lamp 100 can be emitted there-through and the convection current of the air can be facilitated to expedite the effects of the negative ion and the photo catalyst.

[62] The photo catalyst cover 120 is secured to the upper base panel 90 by fastening and engaging with the male thread of the round pipe 122 connected to the bracket 111 of the outer wall in the stabilizer housing and penetrating the through hole 122 A of the glass by means of the female nut 123. In this instance, a rubber packing 124 is inserted between the female nut 123 and the glass to prevent the damage of the glass. A plurality of UVA LED 105 are installed at an inner peripheral surface of the base panel 90 so that they can be turned on concurrently with the lamp, and they improve the action of the photo catalyst by enriching the light source of the lamp, which is the light source of the photo catalyst. Further, the LED can be used as smooth mood light without extinction.

[63] A electric circuit can be constructed to be parallel so that the lamp is extinct with the stabilizer circuit in the housing 110, and the negative ion and the UVA LED 105 can be operated to thereby make the negative ion generator and the UVA LED 105 be turned on continuously, in spite of the extinction of the lamp by means of using a remocon or the string 106. As a result, it is possible to perform the function of producing the negative ion and the function of purifying the indoor air with the photo catalyst.

[64] As the negative ion emitting portion 132 is positioned below the photo catalyst cover 120, the contaminated materials neutralized and precipitated by the negative ions can be quickly and strongly purified by the photo catalyst positioned just above the contaminated materials.

[65] The photo catalyst is used to remove harmful materials or deodorize the bad smells and the like by reacting the harmful materials such as the NOx or the VOC and the like with the photo conducting zone and oxidizing and decomposing the harmful materials. It is required to maintain proper time and wavelength for activating the photo catalyst to react the harmful materials with the photo electron conducting zone, and warm air is required to maintain the proper wavelength.

[66] In general, while the photo catalyst device for use compositely to the home air purifier and the like is used in combination with several filters, and because the air with the harmful materials sucked into forcibly by a fan in view of the structure of the air purifier flows rapidly, the reaction time with the photo catalyst is too short and the efficiency of the reaction is not so high because the proper wavelength cannot be maintained.

[67] According to the purifying apparatus for indoor air used for the lighting of the present invention, because the photo catalyst material is coated on the glass plate formed with a plurality of glass projections 120a below the glass cover 120 of the fluorescent light, the time for reacting with the air containing the circulating harmful materials is long. The heat emitted from the fluorescent light in the glass cover 120 is functioned to increase the reaction efficiency by maintaining the proper wavelength for activating the photo catalyst.

[68] As for the photo catalyst materials, any one of the platinum group including a palladium, a platinum and the like and silver (Ag), manganese (Mn), and the like are mixed in addition to TiO by a proper ratio according to the use and coated to increase the catalyst efficiency. That is, a glass bead made by coating a mixture of the TiO and any one or at least two of the platinum, the silver, and the manganese or a glass bead made by coating the sole TiO is attached on the glass cover and used by means of a transparent binder.

[69] It is possible to facilitate rapid and smooth radiation of the heat from the fluorescent glass tube by coating the materials for radiating far infrared ray on the fluorescent light used in the lighting and radiating the far infrared ray. Therefore, it is possible to help prevent the reduction of the light emitting efficiency and the decrease of the use life due to the unsmooth light emitting, and the far infrared ray can define the absorption wavelength band of the organic compound to thereby facilitate the activation of the photo catalyst wavelength band.

[70] Further, according to the present invention, a perfume cartridge 150 is inserted into a perfume holder clip 152 and attached to the lamp 100 so that the perfume can be emitted through emitting holes 133 by means of the radiation of the heat after the turning of the lamp.

[71] Alternatively, a porous metal sintered body can be attached to the bracket 111 of the outer wall in the stabilizer housing and the pipe 122 by means of binder, and the female nut 123 can be made of the porous metal sintered body to thereby refill the perfume and use it.

[72] Then, when the lamp is turned on, the negative ion is produced incidentally with the turning on of the lamp, so that the ultra violet ray and the visible light ray of the lamp can be radiated on the glass of the photo catalyst together with the ultra violet ray of

the UVA LED to activate the photo catalyst function to thereby purify the indoor air with the effect and functions described above. In this instance, the aroma radiated from the perfume cartridge can produce the excellent synergy effect by combining with the negative ions.

[73] According to the linear tube type FLR, which is of the shape similar to the FPL, the lamp sockets are positioned at both end portions, and the socket and the stabilizer circuit are arranged at the housing positioned at one side. In this case, the stabilizer circuit, the socket, and the negative ion producing unit, and the like are installed to the housing as was in the case of the FPL, and the lower cover glass of the photo catalyst is formed with through hole at the lower side of the both sockets, and is attached to the base panel as was in the FPL. However, the two engaging bolts are positioned at both sides in the FLR, while the engaging bolt of the cover glass in the base panel is only one. Also, the construction, functions and effects of the negative ion, the photo catalyst, the device for radiating the perfume are the same as those of the FPL.

[74] FIG. 7 is an exploded perspective view showing a different embodiment of the present invention. As shown in the drawing, the lighting of the present embodiment is constructed that, the upper portion of the cover glass is identical with FIG. 1, the cover 120 is constructed to be structure of the flat plate glass or of the flat plate plastic, the cover 120 is secured to the lighting base 90 by using securing means 120b (example: a chain, or supporting member) so that it can be hung to the lower portion, the cover 120 is formed with a plurality of projections 120a at the surface thereof, and a glass bead having the nano TiO coating is coated on the surface of the cover. Also, a plurality of UVA LEDs 105 are mounted on the base panel 90 of the lighting. Accordingly, as the cover 120 having a photo catalyst coating, on which the negative ion generator is mounted, is arranged in an opened space with maintaining a proper interval, the contaminated materials neutralized and precipitated by the action of the upper negative ion is strongly oxidized and decomposed by the lower photo catalyst to accomplish the rapid and strong purifying of the indoor air.

[75] FIG. 8 is an exploded perspective view of an FCL having a air purifying and health improving functions, in which the technology of the present invention is applied to another embodiment of the present invention, and FIGs. 9 are partial exploded perspective view and cross-sectional view of FIG. 8.

[76] The FCL of the present embodiment is identical with the FPL in respect of the construction of the negative ion generator, the type of the cover glass of the photo catalyst, the structure of engaging glass with the upper base panel 90, and the like. However, it is different from the FPL in that the UVA LED 105 is mounted at the bracket 111 of the outer wall of the stabilizer housing, and the socket 102 is engaged with the terminal pin of the lamp after it is extended from the stabilizer by means of the electric wire.

Thus, the production of the negative ion, the structure of the photo catalyst and the emission of the perfume, and the functions and effects of the FCL are identical with those of the FPL.

[77] Further, the negative ion emitting portion 132 can be arranged to project to one lower side of the base panel 90 engaged with the cover glass.

[78] FIG. 10 is a perspective view showing whole construction of a fluorescent light having the functions of air purifying and health improving, in which the technology of the present invention is applied to another embodiment of the present invention. As shown in the drawing, a round base panel 90 is mounted to a securing plate attached to the ceiling to which the electric power is applied, and a cylindrical bracket 111 is mounted vertically to the lower of the base panel, and a supporting bracket attaching the lamp 100 and the socket thereof, and a glover supporting bracket 125 enclosing the lamp are formed integrally and mounted to the cylindrical bracket, the upper portion of the cylindrical pipe penetrating through the cylindrical bracket 111 to project downward and formed with the male thread at the lower portion is mounted to the base panel, and the female nut 123 A is provided to engage with the male thread to thereby secure the cylindrical bracket 111 to the base panel 90.

[79] In this structure, the negative ion producing portion unit 130 and the stabilizer circuit unit 112 are installed in the cylindrical bracket 111, and the negative ion emitting tube 131 of the negative ion producing portion is inserted into the pipe extending downward to the cylindrical bracket to project to the lower side thereof as was the string 106. The glass cover 120 enclosing the lamp 100 and coated with the photo catalyst is engaged and attached to the supporting bracket 125 by means of the bolt 121. In this instance, the rubber packing 124 is inserted between the glass and the bracket to prevent the damage of the glass.

[80] A plurality of UVA LEDs 105 are attached to a thin stick type electric wire at the rear upper end of the glass cover 120, and are turned on incidentally with the lamp. They enrich the light source of the photo catalyst and are used as mood lightings after the extinction. Also, a holder clip 152 with a perfume cartridge 150 inserted is mounted to the lamp, and the perfume cartridge emits perfume together with the heat radiation of the lamp. Further, a porous metal sintered body can be formed on the cylindrical bracket 111 by means of the binder, and the female nut 123 can be made of the porous metal to thereby refill the perfume.

[81] The glass cover 120 can be fabricated to be three or four and can show beautiful design of attaching big flower leaves to the ceiling. It is possible to maximize the effect of the photo catalyst by enlarging the photo catalyst supporting zone to the maximum through performing the nano TiO coating on the outer periphery of the securing plate of the ceiling, the base panel 9OA, the cylindrical bracket 111, glove glass racket 125,

and the like. Also, it is possible to prevent the above parts from being contaminated by the fine contaminating materials charged at the time of emitting (If the cylindrical bracket 111 is coated with the metal sintered body containing the perfume, the TiO coating is excluded). When the electric power is applied to the lamp, the lamp is turned on and the negative ion is emitted from the negative ion emitting portion incidentally to neutralize and precipitate the contaminating materials in the indoor air, and then the contaminating materials are oxidized and decomposed by the strong photo catalytic action of the glass cover 120 coated with the photo catalyst arranged above the materials to produce rapid and strong air purifying of the air, and the perfume cartridge attached to the lamp emits the perfume together with the heat radiation of the lamp. Thus, in the lighting mounted to the ceiling of the living room according to the present embodiment, the perfume produces the synergy effect together with the negative ion.

[82] Although it is not shown in the drawings, according to different embodiment of the lamp attached to the ceiling of the living room, a supporting bracket made of metal for attaching 5 - 6 electric bulbs is formed integrally with the round base panel 90 made of metal to which the electric power is supplied, and the present embodiment is identical with the above embodiment in that the fluorescent light is attached at the lower end of the round base panel, the structure of the negative ion generator, and the structure of the glass cover coated with the photo catalyst being attached to the base panel. However, differently from the above embodiment, the bulbs are mounted to the base panel having five or six supporting brackets, the cover glass is coated with the photo catalyst, and the bulb is provided with a plurality of UVA LEDs at the inside. In this regard, the center cover glass and the five to six cover glasses of the bulb, and the like become to be the supporting members for the photo catalyst, and the UVA LED supplies sufficient light source for the photo catalyst to produce excellent effects of the photo catalyst action, and the LED bulbs can be used as mood lightings after the extinction of the round fluorescent light. Thus, the cover glass for the photo catalyst according to the present invention can use the plane glass, and curved glass can be used alternately.

[83] Further, in the present invention, it is possible to attach the glass bead coated with the nano TiO to the outer periphery of the transparent plane or curved glass or plastic having a size of two to five times the area of the base panel of the lamp by using the transparent binder, or it can be hanged to the base panel or securing plate of the ceiling by means of the chain or a hanger pipe after performing the coating of the sol or gel of the nano TiO by using the coating technology of the glass so as to maximize the supporting zone of the photo catalyst with regard to the FPL and FCL shown in FIG 5 through FIG. 10, the FLR having a shape similar to those of the FPL and FCL, and cover glasses for the lamp having a rectangular or square shape.

[84] Meanwhile, a small fan can be further installed to the lower side of the negative ion emitting portion to facilitate the circulation of the air in the respective embodiment described above. Industrial Applicability

[85] As described above, the present invention has advantages in that it is possible to produce large volume of the negative ions continuously without producing harmful materials such as ozone or nitrogen oxide, and it is possible to use separately or to attach easily to the device requiring the emission of the negative ions because the structure is simple and the cost is low to make it possible to apply to various applications, and it is possible to support the health improving of the people and purifying of the indoor air because the structure of the present invention is not affected from the outer environment such as high temperature, and the like to make it possible to use it freely.

[86] Also, according to the complex negative ion, photo catalyst, and air purifying lighting, it is possible to provide the indoor lighting, and purify the indoor air. As a result, it is possible to prevent the increase of the germs in the air due to the filter contamination caused by the poor management of the conventional filter type air purifier, and also to prevent the contamination by the disperse of the accumulated contaminating materials caused by the contamination of the collecting plate due to the poor management of the electrical dust collecting type air purifier. Further, it is possible to purify the air economically and conveniently because the cost for changing the filter can be reduced and the purifying of the dust collecting plate is not required.

[87] In addition, according to the present invention, it is possible to provide more excellent air purifying function in comparison with the conventional sole negative ion emitting lighting, or the lighting using the sole photo catalyst, or the sole air purifying lighting and purify the air ceaselessly. Also, the present invention is advantageous because it is possible to use the lighting almost permanently by changing the lamp in comparison with the conventional disposable air purifying lighting, to accomplish economic effect and environment protection effect.

[88] Moreover, it is possible to improve the human health in addition to purify the air.
