ELECTRIC LAMP SOCKET DEVICE WITH NEGATIVE ION

GENERATOR

Technical Field

[1] The present invention relates to an electric lamp socket device, and more particularly, to an electric lamp socket device with a negative ion generator that is integrally formed at the inside of a housing of a socket of an electric lamp attached on the ceiling or wall of existing indoors in a manner of detachably mounting the electric lamp thereat, thereby preventing hazardous substances like ozone or nitrogen oxides from being generated such that the electric lamp socket device can function as an indoor air purifier, and that is provided with an electric lamp or a lamp shade coated with an optical catalyst material on one surface thereof, thereby improving the air purifying effects thereof. Background Art

[2] Generally, negative ions function to neutralize and deposit all kinds of pollutants like nitrogen oxides, sulfur oxides, hydrocarbon, carbon monoxide, carbon dioxide, volatile organic compound (VOC) like formaldehyde, toluene, and smoke of cigarette, thereby making the surrounding air purified and further removing the offensive odors generated from a variety of bacteria. Additionally, the negative ions function to help various kinds of hazardous electromagnetic waves neutralized and to prevent or heal various chronic diseases like neuralgia, asthma, insomnia. Further, they function to make the human beings activated to recover from their fatigue, while helping them free from their stress and their concentration more improved.

[3] To utilize such the good effects of the negative ions, a negative ion generator has been introduced to an air purifier, or a stand type of negative ion air purifier has been produced. The negative ion air purifiers have some advantages in that there is no need for cleaning and exchanging filters, thereby requiring no maintenance costs therefor, no noise is generated, and its size is compact, thereby requiring relatively small areas for installation. However, most of the negative ion air purifiers adopt a manner (see Korean Patent Laid-Open Publication No.1990-00123) of applying a high voltage to a metal needle point discharge electrode, thereby making the surrounding air purified, such that undesirably, ozone and nitrogen oxides are additionally generated upon the generation of negative ions. More especially, it is noted that there is a possibility that even a quantity of ozone under a reference vale at a closed space may be seriously harmful to human bodies.

[4] As one of prior arts related to a negative ion generating lamp device, there has been proposed a negative ion generating air conditioning apparatus (which is disclosed in Korean Patent Application No.2001-71131), which works in the same manner of applying a high voltage to a needle point for generating the negative ions. This also does not avoid the problems the conventional negative ion generating air purifiers have.

[5] The conventional lamp device with the negative ion generator is constructed in such a manner that a lamp is integrally formed to a lamp device body having a lamp driving circuit and the negative ion generator disposed at the inside thereof. Thus, if the lifespan of the lamp is elapsed, the negative ion generator itself is of a discharge type such that the negative ions including pollutants like ozone and nitrogen oxides are undesirably generated.

[6] The conventional negative ion generators that are disposed at the stand type of negative ion generating air purifiers or lamp devices have the pollutants that are deposited during the ionization on air of the discharge electrode undesirably attached to the discharge electrode, thereby making the negative ion generating efficiency substantially low. Unfortunately, such the problem is not solved at all through any conventional practices.

[7] The electric lamp socket device with the conventional negative ion generator is structured in a manner of having the needle point discharge electrode, but in this structure, the hazardous substances (ozone, nitrogen oxides, or the like) are additionally generated from the negative ion generator itself. Furthermore, the electric lamp driving circuit unit and the negative ion generator circuit unit are all formed integrally with the lamp socket, and as a result, if the lifespan of the lamp is elapsed, the whole units should be inconveniently exchanged into new ones, which makes the maintenance costs undesirably high. Disclosure of Invention Technical Problem

[8] Accordingly, the present invention has been made to solve the above-mentioned problems occurring in the prior art, and it is an object of the present invention to provide an electric lamp socket device with a negative ion generator wherein the negative ion generator is mounted at the inside of an electric lamp socket, thereby keeping the hazardous substances like ozone or nitrogen oxides generated additionally from existing negative ion generators from being generated when negative ions are emitted.

[9] It is another object of the present invention to provide an electric lamp socket device with a negative ion generator wherein only a negative ion generating unit is disposed at the inside of a socket housing and socket parts coupled to a general electric lamp are disposed at the lower portion of the socket housing, unlike existing lamp devices with a negative ion generator, such that only when the lifespan of lamp is elapsed, the lamp is exchanged and the socket where the negative ion generator is mounted is still usable, thereby making the maintenance costs greatly saved.

[10] It is still another object of the present invention to provide an electric lamp socket device with a negative ion generator wherein a lamp shade is further provided at the outside of the lamp socket, the lamp shade being coated with an optical catalyst material such that air purification is conducted through the action of the optical catalyst material.

[11] It is yet another object of the present invention to provide an electric lamp socket device with a negative ion generator wherein a lamp socket having the negative ion generator mounted at the inside thereof serves to generate negative ions from the electric lamp like incandescent lamps and to clean indoor air through the action of optical catalyst material coated on the lamp shade, thereby being utilized as an indoor air purifier.

[13] It is a further object of the present invention to provide an electric lamp socket device with a negative ion generator wherein a socket housing having the negative ion generator mounted at the inside thereof is provided with a socket disposed at the lower portion thereof for coupling the lamp and a plug disposed at the upper portion thereof for coupling directly with a wall outlet, thereby making the lamp device conveniently coupled to the wall outlet.

[27] In case where the electric lamp is the encased lamp, the negative ion discharging tube is drawn from the side of the socket housing and is extended downwardly along the side of the lamp such that the negative ion discharging part is disposed at the side lower portion of the lamp.

[28] The lamp shade of the encased lamp is coated with an optical catalyst material on the inner surface directly irradiated with the light of the lamp.

[51] (First Embodiment)

[52] FIG. 1 is a schematic sectional view showing the structure of an electric lamp socket device with a negative ion generator according to a first embodiment of the present invention.

[53] As shown, a socket housing 110 is provided with a support plate 113 formed at the inside thereof, and a negative ion generator is mounted on the support plate 113. The negative ion generator is comprised of a set of a high voltage generating unit 130, a negative ion discharging tube 131, and a negative ion discharging part 132.

[54] The high voltage generating unit 130, which is formed of a packaged unit of a transformer, a rectifying circuit, a condenser, and a high voltage amplifying circuit, is mounted on the support plate 113. The negative ion discharging tube 131 is passed through the bottom portion of the support plate 113 from the high voltage generating unit 130 to the outside of one side of the socket housing 110, and thus, the negative ion discharging part 132, which is connected to one end of the negative ion discharging tube 131, is exposed to the outside. An electric lamp 100, which is freely selected from a fluorescent lamp or incandescent lamp, is formed in such a manner that a bolt socket part 101 of the electric lamp 100 is insertedly fit to a nut socket part 111 detachably mounted at the lower end portion of the socket housing 110.

[55] Also, the socket housing 110 is further provided with a lamp switch 83 manipulated through a switch manipulating means exposed protrudingly to the outside for selectively turning on/off only the electric lamp 100.

[56] The socket housing 110 may be separated into upper and lower parts or vertically cut two parts, which is not shown, though.

[57] The socket housing 110 is formed in such a manner that the support plate 113 on which the lamp switch 83 and the high voltage generating unit 130 are mounted is disposed at the inside thereof and a wiring metal and wiring connected to the nut socket part 111 at the lower end portion thereof are provided. In this case, the wiring for the nut socket part 111, the lamp switch 83, the high voltage generating unit 130, and an outside input power supply wire 80 are not shown in the drawings, but since the technology related thereto is obvious to those skilled in the art, it is avoided in the de- scription of this invention.

[58] That is, the outside input power supply wire 80 is turned on and off by a main switch mounted on a wall, and the power supply passed through the input power supply wire 80 is connected as the input power supply to the high voltage generating unit 130. Also, it is connected as the input power supply to the nut socket part 111 through the manipulation of the lamp switch 83. In this case, only the electric lamp 100 is turned on/off through the manipulation of the lamp switch 83, and the lamp switch 83 is freely selected from a button type switch as shown, a string switch, and a wireless remote control switch, in accordance with the purposes and kinds of products.

[59] Therefore, a lamp switch put on the indoor wall surface serves as the main switch for turning the input power supply wire 80 on/off, and if the main switch is turned on, the power supply is provided to the high voltage generating unit 130, thereby making negative ions emitted from the negative ion generator. At this time, if the lamp switch 83 is manipulated, the electric lamp 100 is selectively turned on/off.

[60] The formation of the electric lamp socket device with the negative ion generator mounted at the socket housing basically prevents the pollutants like ozone or nitrogen oxides generated additionally during the generation of negative ions from being generated.

[61] FIGS.2 to 6 show the structures of the negative ion generator employed in the electric lamp socket device according to the present invention. The negative ion generator of this invention includes, as shown in F1G.2, the high voltage generating unit 130 that is formed of a casing impregnated with a strong insulating material like ceramic for housing circuit parts for generating high voltage with the input power supply, the negative ion discharging tube 131 for transmitting a negative high voltage from the high voltage generating unit 130 to a discharging pin, and the negative ion discharging part 132 for emitting the negative ions to the air through the discharging pin attached to the end portion of the negative ion discharging tube 131.

[62] The high voltage generating unit 130 is formed of an independent casing, but may be formed in a manner of mounting the negative ion generating circuit parts on the top surface of the support plate 113, as shown in F1G.2.

[63] F1G.3 is a sectional view showing a negative ion discharging tube of F1G.2. The negative ion discharging tube 131 includes a plurality of conductive wires 11 coated with a plurality of negative ion generating substances and a cladding tube 12 coated with the negative ion generating substances at the inner wall thereof for insulating the plurality of conductive wires 11 from the outside. The discharging pin of the discharging part 132 is coated with TiO .

[64] A reference numeral 11a denotes a coated film with a tourmaline or mineral solution, and a reference numeral 12a denotes a coated film with tourmaline powder or mineral powder on the inner wall of the cladding tube 12.

[65] The tourmaline solution of a nano or micron unit is coated as the negative ion generating substances, or negative ion and far-infrared ray generating substances that are made by mixing the tourmaline solution and one or two substances like kiyoseki, mineral stone, Geumgangyakdol, sericite, and biotite.

[66] The plurality of conductive wires 11 of the negative ion discharging tube 131 are formed of plural metal conductive wires in such a manner of being housed in the cladding tube 12, and they are made of an aluminum alloy material having high conductivity and heat-resistance.

[67] Moreover, the cladding tube 12 is formed of a silicon rubber cladding material coated at the inner wall thereof with one substance or two or more mixed substances selected from the tourmaline solution, the negative ion and far-infrared ray generating minerals like kiyoseki, and ultra fine powder like Binchotan.

[68] F1G.4 is a sectional view showing another example of the negative ion discharging tube of F1G.2. The negative ion discharging tube 131 is cut in the middle portion thereof and the two cut portions are spaced apart by lcm to 4cm. Then, fine powder 13 of minerals like kiyoseki is placed between the two cut portions and the cut conductive wires 11 are fixed at the both ends. Next, a clapping tube 12', which is coated with tourmaline and mineral powder at the inner wall 12'a thereof, surrounds the space in which the fine powder 13 is filled.

[69] The discharging pin of the negative ion discharging part 132 connected to the end portion of the negative ion discharging tube 131 is formed of several metal alloys. The discharging pin may be formed of a plurality of pins, as shown in F1G.2, and may be formed of a needle, as shown in F1G.5. Further, it may be formed of a bundle of metal threads each having a size between 2 to 5 microns, the metal thread being made of an alloy of stainless, titanium, aluminum, copper, and so on. Even though the discharging pin is of any shape, the negative ion discharging part 132 is coated with a nano TiO solution.

[70] According to the negative ion generator employed in the electric lamp socket device of the present invention, the conductive wires of the negative ion discharging tube and the inner wall of the cladding tube are coated with tourmaline solution and powder or mineral, and the negative ion discharging part is coated with the TiO solution. As a result, the negative ions are emitted from the coated materials, and therefore, since they are not generated by sparkling the discharge electrode in the conventional practice, the pollutants like ozone or nitrogen oxides are not basically accompanied during the generation of the negative ions. Moreover, as the negative ion discharging part is coated with the nano TiO , it is protected from the contamination thereof, without any reduction of the negative ion generating efficiency. [71] According to the lamp socket with the negative ion generator of this invention, if power supply is applied, the lamp is turned on and at the same time, the negative ions are emitted. The lamp is turned on and off by the manipulation of the lamp switch 83, and so as to keep the negative ions emitted after the lamp has been turned off, the input power supply wire 80 is directly connected to the high voltage generating unit 130, for keeping power supply applied thereto. Additionally, a lamp on/off remote control circuit part is mounted on the support plate 113, for radio-controlling the turning the lamp on/off.

[72] According to the first embodiment of the present invention, the negative ion generator is provided at the inside of the socket housing, and if the lifespan of the lamp is elapsed, only the lamp is exchanged into new one such that the present invention is used at maintenance costs of one-fifth of existing negative ion generating lamp devices, thereby making it convenient in use and economical at the maintenance costs.

[73] F1G.7 is an exemplary view showing the use state of the electric lamp socket device of FlG.1 wherein the lamp and the glass lamp shade are all mounted thereon.

[74] The socket housing 110 of FlG.1 is provided with the nut socket part 111 at the lower portion thereof, and the nut socket part 111 is coupled with a glass lamp shade

120. The glass lamp shade 120 is provided with an optical catalyst-coated film 120a formed at the outer surface thereof. The nut socket part 111 is provided with punched holes formed at the both sides thereof in such a manner as to have bolts 121 inserted thereinto for coupling with the glass lamp shade 120, and the glass lamp shade 120 is provided with punched holes formed at the top ends thereof in such a manner as to have the bolts 121 inserted thereinto. As a result, the top ends of the glass lamp shade 120 and the lower ends of the nut socket part 113 are coupled by means of the bolts

121, and upon coupling, a rubber packing 121a is inserted between them. A reference numeral 150 denotes a perfume cartridge in which perfume is impregnated or stored as a solution therein, thereby gently emitting the perfume therefrom.

[75] On the other hand, a porous metal sintered material may be coated on the outer surface of the socket housing, and a perfume solution is impregnated in the porous metal sintered material, such that it can be used as a perfume generator and also, it can be refilled.

[76] The electric lamp 100 is coupled with the nut socket part 111 at the inside of the glass lamp shade 120, and the perfume cartridge 150 is inserted into the electric lamp 100. Further, a plurality of discharge holes 122 are punched through the inner and outer peripheries of the glass lamp shade 120, for making the perfume emitted and the air stream rapider, thereby accelerating the generation of the negative ions and optical catalyst material and the emission of perfume. Thus, the electric lamp 100 is better useful when used over the table in a kitchen since it can remove or purify food or gas smell.

[77] In this case, the glass lamp shade 120, which is made of glass or transparent plastic, is provided with some groups of the plurality of discharge holes 122 formed around the lower side of the middle periphery thereof and with the optical catalyst-coated film 120a formed on the outer surface thereof in such a manner that glass bead coated with nano TiO responding to visible light or ultra-violet rays is attached by means of a transparent binder onto the outer periphery of the glass lamp shade. Otherwise, a porous thin film is formed on the outer periphery of the glass lamp shade 120, and then, a nano TiO sol or gel is coated thereon for forming the optical catalyst-coated film 120a.

[78] As a result, the optical catalyst-coated film 120a responds to the visible light or ultra-violet rays by indoor natural illumination or by the light of the electric lamp 100, thereby making the indoor air freshly purified.

[79] (Second Embodiment)

[80] FIG.8 is a sectional view showing an electric lamp socket device with a negative ion generator according to a second embodiment of the present invention, wherein the electric lamp socket device adopts an encased lamp.

[81] As shown, a socket housing 200 is provided with a support plate 213 formed at the inside thereof, and a high voltage generating unit 130 is mounted on the support plate 213. A negative ion discharging tube 131 of the high voltage generating unit 130, which is passed through the bottom portion of the support plate 213, is extended to the outside of one side of the socket housing 200, and a negative ion discharging part 132, which is connected to one end of the negative ion discharging tube 131, is exposed to the outside of one side of the socket housing 200.

[82] The socket housing 200 is provided with the nut socket part 111 for coupling with the electric lamp at the lower portion thereof and is provided with a bolt socket part 215 coupled with a general lamp socket at the upper end portion thereof.

[83] The negative ion generator, which is comprised of the high voltage generating unit

130, the negative ion discharging tube 131, and the negative ion discharging part 132, has the same structure as shown in the first embodiment of the present invention.

[84] FIG.8 shows the second embodiment of the present invention where the electric lamp socket device adopts the encased lamp, wherein a nut socket part 172 is disposed at the central inside of the electric lamp socket device and a lamp shade 170 for the encased lamp that takes a shape of a fallopian tube is disposed to encompass the electric lamp. Further, a support stand 171 is formed at the outside of the lamp shade 170 for supporting and protecting the encased lamp. In this embodiment, when the bolt socket part 215 formed at the upper portion of the socket housing 200 is coupled for use with the nut socket part 172 of the encased lamp, if the negative ion discharging part 132 of the negative ion generator is formed at the outer side of the socket housing 200, it is closed by means of the lamp shade such that no negative ion emission effect occurs. Thus, the negative ion discharging tube 131 is drawn from one side of the socket housing 200 and is extended downwardly to one side of the electric lamp 100 such that the negative ion discharging part 132 is disposed at the lower end of the electric lamp 100.

[85] Under the above structure, the bolt socket part 215 formed at the upper portion of the socket housing 200 having the negative ion generator of this invention is insertedly coupled with the nut socket part 172 of the encased lamp, and the nut socket part 111 formed at the lower end of the socket housing 200 is coupled with the bolt socket part 101 of the electric lamp 100.

[86] As a result, when the lifespan of lamp is elapsed, only the electric lamp 100 is exchanged into new one, while keeping the function of the negative ion generator done. Namely, the negative ion generator is mounted in the socket housing, and only the electric lamp is detachably mounted thereon, such that the present invention is economically used at a maintenance cost of one-fifth of existing negative ion generating lamp devices, thereby giving economical savings, and the electric lamp can be easily purchased everywhere, thereby making it convenient in use.

[87] In case of mounting the negative ion generator according to the present invention, the negative ion discharging part is disposed at the lower portion of the electric lamp, such that the air purifying effect can be sufficiently obtained.

[89] FIG.9 is a sectional view showing an electric lamp socket device with a negative ion generator according to a third embodiment of the present invention wherein a plug is attached to the socket housing, such that the electric lamp socket device is utilized as both the negative ion generator and the indirect lamp. In this structure, the negative ion discharging part 132 is protruded from the outside of the socket housing 200, and instead of the bolt socket part formed on the upper portion of the socket housing 200, a plug 217 is connected with a wall outlet. A nano TiO -coated optical catalyst coating film 200a is formed on the outer surface of the socket housing 200, and the socket housing is further provided with a lamp switch 83 for turning on/off only the electric lamp 100. In this case, the negative ion generator, which is comprised of the high voltage generating unit 130, the negative ion discharging tube 131, and the negative ion discharging part 132, has the same structure as shown in the first embodiment of the present invention.

[90] Under the above structure, when the plug 217 is coupled with the wall outlet, the negative ions are generated and indirect illumination is made. Also, under the above structure as shown in FIG.9, the nano TiO -coated optical catalyst coating film 200a that responds to visible light or ultra violet rays is formed on the outer surface of the socket housing 200, thereby obtaining high optical catalyst effects, and at the same time thereby preventing fine pollutants occurring upon discharge of the negative ion generator from being attached to the socket housing 200.

[91] The lamp switch 83 is manipulated to turn only the electric lamp 100 on/off, such that if the plug is connected to the wall outlet at a state of turning the lamp off, only the negative ion generator works. Thus, if necessary, only the negative ion generator works according to the manipulation of the lamp switch, or the electric lamp socket device is utilized as both the negative ion generator and the indirect lamp.

[92] (Fourth Embodiment)

[93] FIG.10 is an exploded perspective view showing an electric lamp socket device with a negative ion generator according to a fourth embodiment of the present invention wherein the electric lamp adopts a fluorescent lamp, and FTG.11 is a sectional view showing the structure of a socket housing separated from the lamp of FIG.10.

[94] A support plate 313 is disposed at the inside of a socket housing 300, and stabilizer circuits 316 and a high voltage generating unit 130 are mounted on the support plate 313. The negative ion discharging tube 131 of the high voltage generating unit 130 is passed through the stabilizer circuits 316 and is extended to the outer side of the socket housing 300 such that the negative ion discharging part 132 is protruded therefrom. The socket housing 300 has a lamp coupling means formed at the lower end thereof and has a bolt socket part 315 formed at the top end thereof.

[95] The lamp for coupling at the bottom end portion of the socket housing 300 is provided with a fixing plate 102 made of an insulating material and formed on the upper end of a lamp tube 100 and with two socket pins 103 protruded on the top surface of the fixing plate 102, the two socket pins being connected to the power terminals of the lamp tube 100. The socket housing is provided with semi-oval grooves 311 formed at the bottom end portion thereof in such a manner as to detachably mount the socket pins 103 at the bottom surface of the socket housing 300 and with electrodes formed in the interior of the semi-oval grooves 311 in such a manner as to be connected electrically with the socket pins 103, the electrodes being connected with the stabilizer circuits 316.

[96] Namely, like the insertion of a glow start lamp of a magnetic stabilizer, the lamp is detachably mounted in such a manner where the semi-oval grooves 311 are formed in pair to make the two socket pins 103 connected to the lamp tube 100 detachably mounted thereto with ease, and the power connecting parts are mounted at the inside of the grooves for connection with the stabilizer circuits.

[97] Under the above structure, only the lamp tube 100 is exchanged with new one, not changing the stabilizer and the negative ion generator, like the FPL or FCL, such that the present invention is economically used at a maintenance cost of one-tenth of existing florescent lamps, thereby giving economical savings, and no soldering parts used on the various stabilizer circuits and the negative ion generating circuits are needed, thereby giving no damage on our environments.

[98] Also, the socket housing is further provided with the lamp switch 83 that is manipulated by means of a switch manipulating means extruded to the outside for selectively turning on/off only the electric lamp.

[99] The socket housing 300 may be formed as two separate units, even though they are not shown in the drawing, such that the lamp switch 83 and the support plate 313 on which the high voltage generating unit 300 is mounted are formed at the inside of the socket housing 300 and the metal electrodes and wires disposed at the grooves 311 at the bottom portion of the socket housing 300 are connected, thereby finishing the assembling of the socket housing 300. The wiring for the electrodes of the bolt socket part 315 formed on the top portion of the socket housing 300, for the metal electrodes disposed at the inside of the grooves 311 at the bottom portion of the socket housing 300 for the connection with the lamp socket pins 103, for the lamp switch 83, and for the high voltage generating unit 130 are not shown in the drawings, and since the wiring techniques are obvious to those skilled in the art, they are avoided for the brevity of the description.

[100] That is, the bolt socket part 315 that is formed on the top portion of the socket housing 300 is coupled with the existing lamp socket such that the power supply to the high voltage generating unit 130 is turned on/off by means of the main switch mounted on an outside wall. Thus, the input power through the bolt socket part 315 is connected as input power to the high voltage generating unit 130, and at the same time, it is supplied by means of the lamp switch 83 to the stabilizer circuits 316. Then, the input power of the stabilizer circuits 316 is connected to the metal electrodes at the inside of the grooves 311 and the socket pins 103 of the lamp tube 100, thereby turning the lamp on/off. Namely, only the lamp can be turned on/off by means of the manipulation of the lamp switch 83, and the lamp switch 83 may be selected from any one of button type, string type, or wireless remote control type in accordance with the purposes and kinds of products.

[101] The lamp switch that is disposed at the indoor wall surface becomes the main switch for turning the power supply wire 80 on/off, and if the main switch is turned on, the power supply is applied to the high voltage generating unit 130, thereby emitting negative ions. When the lamp switch 83 is manipulated, only the electric lamp 100 can be selectively turned on/off.

[102] According to the fourth embodiment of the present invention, the electric lamp socket device with the negative ion generator mounted therein has more improved negative ion generator when compared with existing ones, wherein the negative ion generator in this embodiment has the same structure as in the first to third embodiments. The pollutants like ozone or nitrogen oxides are inevitably generated in the existing negative ion generators, but the negative ion generator embodied in the present invention fundamentally prevents the generation of such the pollutants.

[103] On the other hand, the nano TiO -coated optical catalyst coating film that responds to visible light or ultra violet rays is formed on the outer surfaces of the socket housing 200 and the lamp tube 100, thereby obtaining high optical catalyst effects, and at the same time thereby preventing fine pollutants occurring upon the discharge of the negative ion generator from being attached to the socket housing 200. This prevents the socket housing 300 from being dark or prevents the lamp tube 100 from being dim.

[104] FlG.12 is a sectional view showing the whole structure of the electric lamp socket device where the lamp of FlG.10 is mounted as an encased lamp. In this case, the nut socket part 172 is disposed at the central inside of the top end portion of the electric lamp socket device, and the lamp shade 170 for the encased lamp that takes a shape of a fallopian tube for mounting the socket housing 300 thereunto is disposed at the lower portion of the electric lamp socket device around the outside of the lamp. The negative ion discharging tube 131 is drawn from one side of the socket housing 300 and is extended downwardly to one side of the lamp tube 100 such that the negative ion discharging part 132 is disposed at the lower end of the lamp tube 100. And, an optical catalyst coating film 170a is formed on the inner surface of the lamp shade 170, and the support stand 171 is formed at the outside of the lamp shade 170 for supporting and protecting the encased lamp.

[105] The negative ion generator and the stabilizer circuits are still coupled with the nut socket part 172 for the encased lamp, and the lamp tube 100 can be simply mounted like the glow start lamp, thereby making it convenient to use. The encased lamp of this invention is economically used at a cost of one-twentieth of existing negative ion g enerating florescent lamps, thereby giving economical savings. Also, the nano TiO - coated optical catalyst coating film is formed on the outer surfaces of the socket housing and the lamp tube. In this case, if the optical catalyst material is coated on the lamp shade, no coating is desirably applied to the lamp tube. Industrial Applicability

[106] According to the present invention, the electric lamp socket device is provided with a negative ion generator mounted at the inside of a socket housing for keeping the hazardous substances like ozone or nitrogen oxides from being generated, in such a manner as to detachably mount an electric lamp to the socket housing, thereby functioning as an air purifier according to the generation of the negative ions.

[107] Further, the electric lamp socket device of this invention has an optical catalyst material coated on a lamp shade or an outer surface of the socket housing such that the smell of food or gas occurring upon cooking is removed and purified, thereby being useful as a lamp for the kitchen table.

[108] In case where the socket housing of the electric lamp socket device of this invention has a plug at the top end portion thereof, the plug is coupled with a wall outlet, thereby functioning as both the negative ion generator and the indoor indirect lamp.
