WO 2008/050934 PCT/KR2006/005485 1 Description VERMIN EXTERMINATING APPARATUS Technical Field [1] The present invention relates to a vermin exterminating apparatus and, more par ticularly, to a vermin exterminating apparatus capable of exterminating vermin by using a means that does not harm animals and plants. Background Art [2] In general, vermin refer to insects or bugs that do harm directly or indirectly to the human's life. Directly harmful insects include fleas, louses, housebugs, mosquitoes, bees, Oriental tussock moths, and ants, etc. Indirectly harmful insects include agri culturally noxious insects such as aphids or leafhoppers harmful to crops, stored crop noxious insects such as rice weevils or cockroaches generated from the stored crops, livestock noxious insects such as mosquitoes and flies harmful to domestic animals, food insects generated from dairy products or dried goods, and environmental hygiene insects such as flies and cockroaches that carry infectious diseases, and the like. In particular, the agriculturally noxious insects not only reduce the earnings of farmers by degrading the crops but also aggravate the shortage of foods which is at issue throughout the world. [3] In order to exterminate vermin, various insecticides can be used to be sprayed, natural enemies of vermin can be released, or phototaxis can be used to induce and kill vermin. Meanwhile, as the insecticide, chemically synthesized agrichemicals are typically used, and as a device using phototaxis of vermin, an induction insect trap or an electric shock device is typically used. [4] However, the related art vermin exterminating method by the insecticide has problems that tolerance of vermin to agrichemicals increases to make the effects of vermin exterminating gradually reduced and residual agrichemicals of the crops are cu mulatively stored in the human bodies, seriously threatening the human beings. [5] Recently, regulations for the use of chemical fertilizers and the argichemicals are being reinforced by the international agreements such as a WTO agreement or a UNCCC. Thus, diverse microbic agrichemicals harmless to the crops and human bodies have been developed and several environment-friendly agricultural methods using natural enemies have been presented. However, the microbic agrichemicals and environment-friendly agricultural methods, etc., are not much effective in ex terminating vermin compared with the case of using the chemical fertilizers or agri chemicals. [6] According to the method for exterminating vermin by the induction insect trap, WO 2008/050934 PCT/KR2006/005485 2 vermin are induced along light to an insecticidal chamber so as to be captured or ex terminated therein in various manners. The insecticidal chamber includes an in secticide, an adhesive to which vermin are to be attached, or a fan blade for applying physical blow to vermin, etc. The electric shock device is operated to induce vermin by light to its lattice to which high pressure electricity is applied, so as to get shocked by the high pressure current of the lattice. [7] However, the induction insect trap and the electric shock device can exterminate only adult insects that can be induced by light, leaving ova or larvae alive, so basic prevention of the breeding and extermination is not possible with such devices. In addition, the induction insect trap and electric shock device are disadvantageous in that they need a follow-up control when used for a long time, for example, the insecticide should be supplemented, the adhesive should be changed, the fan and the lattice should be cleaned, and the like, and in addition, their maintenance fees increas considerably. Moreover, large moths or large beetles of vermin can be hardly exterminated by the in secticide and the electric shock, and could easily escape the adhesive. Disclosure of Invention Technical Problem [8] Therefore, an object of the present invention is to provide a vermin exterminating apparatus capable of effectively exterminating vermin with a means harmless to animals and plants and being easily managed in terms of its follow-up control. Technical Solution [9] To achieve the above object, there is provided a vermin exterminating apparatus including: a light source unit that scans a light ray with wavelength that physio logically disturbs vermin; and a controller connected with the light source unit to control an operation of the light source unit. [10] The light ray of the light source may include a visible ray of at least one of blue color and violet color groups. Namely, the light ray of the light source unit may include a light ray with a wavelength band of 380nm to 500nm. In addition the light ray of the light source unit may include a light ray with wavelength that may induce vermin. The light ray that induces vermin of the light source unit can be a visible ray of a red color group with respect to diptera and can be a visible ray of a yellow color group or an orange color group with respect to vermin of homoptera. The light ray of light source unit may include a light ray with wavelength that may help raise plants. Multiple light source units can be disposed and each light source unit may generate light rays each with a different wavelength band. [11] The controller may control the light source unit to be repeatedly turned on or off instantly at night to scan light rays in the form of a flash. The controller may control WO 2008/050934 PCT/KR2006/005485 3 the light source unit to be in a lights-out (turn-off) mode in which the light source unit is turned off during a first pre-set time and in a lighting-up (turn-on) mode in which the light source unit is turned on during a second pre-set time alternately and repeatedly at night. Or, the controller may control the light source unit to be in the turn-off mode in which the light source unit is turned off during a first pre-set time and in a turn-on mode in which the light source unit is repeatedly and instantly turned on and off during a second pre-set time, alternately and repeatedly at night. The controller may repeat the turn-off mode and the turn-on mode until the operation number of the turn-off mode and the turn-on mode reaches a pre-set number. [12] The vermin exterminating apparatus may further include a housing having the light source unit and the controller disposed therein and an opening formed on a front surface thereof, a reflector disposed at the interior of the housing, the light source unit and the controller being mounted thereon, and reflecting a light ray of the light source unit to the opening, a transparent plate disposed at the opening, a fixing cover detachably combined on the front surface of the housing and fixing the transparent plate and the reflector at the opening, and a support with one side connected with the housing and the other side having a clamp. The vermin exterminating apparatus may fu rther include a sensing unit disposed at one side of the housing and sensing external light and a display unit disposed at the other side of the housing and displaying whether a device is operated or not. [13] At least one of the housing and the transparent plate may include a heat release hole. A water drain hole may be formed at a lower portion of at least one of the housing and the fixing cover in order to drain water from the interior of the housing to the exterior. A reflection face may be formed at multiple angles on the front side of the reflector in order to diffusely reflect the light ray of the light source unit, and a plated layer including a metallic material may be formed on the reflection face. [14] The light source unit may include a lamp disposed on the front surface of the reflector and physiologically disturbing vermin, and a filter plate disposed at a front side of the lamp and filtering a light ray with a particular wavelength among light rays of the lamp. The filter plate may be disposed on a front surface of the transparent plate and the fixing cover may include a fixing member for fixing the filter plate disposed on the front surface of the transparent plate. [15] The vermin exterminating apparatus may include a blocking plate rotatably connected at an upper portion of the front side of the fixing cover in order to cover and protect the front side of the transparent plate as necessary as well as blocking direct light rays introduced into the housing. An upper portion of the blocking plate may be connected to be rotatable at an angle within the range of 100'to 160 0 at the fixing cover, and the fixing cover may include a fixing member that fixes the blocking plate WO 2008/050934 PCT/KR2006/005485 4 covering the transparent plate. Advantageous Effects [16] The vermin exterminating apparatus according to the present invention is ad vantageous in that it can effectively exterminate most vermin by the light ray with wavelength that physiologically disturbs vermin and thus prevent various damages possibly caused by vermin. [17] In addition, the vermin exterminating apparatus according to the present invention is also advantageous in that because vermin are exterminated by using the light ray harmless to animals and plants, environment-friendly and harmless agricultural products can be produced and the problem that chemically synthesized argichemicals are accumulated in the human bodies can be prevented. [18] Moreover, the vermin exterminating apparatus according to the present invention is also advantageous in that because vermin can be effectively exterminated, the yield of the agricultural products can increase and clean agricultural products can be cultivated at a low cost, increasing the income of farm households. [19] Furthermore, the vermin exterminating apparatus according to the present invention is also advantageous in that because it has a simple structure, it can be simply fabricated at a low cost and simply managed in terms of follow-up control, and its management cost can be reduced.

[36] FIGs. 1, 2 and 3 are perspective, exploded perspective, and bottom views showing a vermin exterminating apparatus 1 according to one exemplary embodiment of the present invention, FIG. 3 is a front view showing the vermin exterminating apparatus with a blocking plate 90 closed in FIG. 1, FIG. 5 is a sectional view taken along line A-A in FIG. 4, FIG. 6 is a perspective view showing a rear side of a fixing cover 40 in FIG. 2, FIGs. 7 and 8 are perspective views showing a vertically rotatable part 54 and a horizontally rotatable part 55 of a support 50 in FIG. 2, FIG. 9 is a graph of strength according to wavelength bands of a light source unit 60 in FIG. 2, and FIG. 10 is a graph of visible ray regions in FIG. 9. [37] With reference to FIGs. 1 and 2, the vermin exterminating apparatus 1 according to the present invention includes a housing 10 with an opening 11 formed at a front side thereof, a reflector 20 disposed within the housing 10, a transparent plate 30 disposed at the opening 11, a fixing cover 40 detachably mounted at the front side of the housing 10 in order to fix the transparent plate 30 and the reflector 20 to the opening 11, a support 50 with one side connected with the housing 10 and having a clamp 51 provided at the other side thereof, a light source unit 60 disposed at a front side of the reflector 20 and scanning a light ray with wavelength that physiologically disturbs vermin, and a controller 70 disposed at a rear side of the reflector 20 and controlling the light source unit 60. [38] The housing 10 is a semispherical member with a hollow interior to allow the light source unit 60, the controller 70, and the reflector 20 to be disposed therein. A plurality of heat release holes 12 are formed to be spaced apart from each other on the housing WO 2008/050934 PCT/KR2006/005485 6 10 in order to prevent the light source unit 60 and the controller 70 from being overheated. A plurality of water drain holes 13 are formed to be spaced apart from each other at a lower portion of the housing 10 in order to externally drain moisture or water generated due to a temperature difference within the vermin exterminating apparatus 1. The heat release holes 12 and the water drain holes 13 are slots formed long in a forward/backward direction on the housing 1, which are disposed separately along a circumferential direction at the side of the housing 10. [39] With reference to FIGs. 2 and 4, the vermin exterminating apparatus 1 further includes a sensing unit 80 and a display unit 81 formed at the housing 10. First and second hole portions 14 and 15 are formed at positions of the housing 10 that can be easily recognized by a user. The sensing unit 80 for sensing external light is disposed at the first hole portion 14, and the display unit 81 for displaying whether the vermin exterminating apparatus 1 is operated or not is disposed at the second hole portion 15. The sensing unit 80 includes a light sensor that senses light introduced through the first hole portion 14, and the display unit 81 includes an LED that emits light externally through the second hole portion 15. As a matter of course, the display unit 81 may employ an LCD, an OLED and an electric bulb. Accordingly, the vermin ex terminating apparatus 1 may not only automatically sense the daytime and the night time by means of the sensing unit 80 but also inform the user whether the vermin ex terminating apparatus 1 is operated or not. The sensing unit 80 and the display unit 81 can be formed as a single module and fixed together within the housing 10 by using a fastening member 83. [40] With reference to FIGs. 2 and 5, the reflector 20 has a funnel shape extending toward the opening 11 and is disposed within the housing 10. A flange portion 21 is protrusively formed along the circumference of an outer end portion of the reflector 20 and mounted on mounting members 16. The mounting members 16 refer to protrusions formed to be spaced apart along a circumferential direction on an inner surface of the housing 10. The controller 70 is mounted at the rear side of the reflector 20, and the light source unit 60 connected with the controller 70 is disposed at the front side of the reflector 20. [41] A reflection face 22 is formed at multiple angles on a front surface of the reflector 20 to diffusely reflect a light ray of the light source unit 60, and a plated layer 23 made of a metallic material having reflexibility and heat resistance is formed on the reflection face 22. The plated layer 23 is made of a chromium material. Accordingly, the reflection face 22 of the reflector 20 can be prevented from being degraded or the color of the reflection face 22 cannot change, and every light ray of the light source unit 60 can be externally irradiated through the opening 11. [42] With reference to FIG. 2, the transparent plate 30 is a disk type member made of a WO 2008/050934 PCT/KR2006/005485 7 transparent material and inserted within the housing 10 so as to be mounted on the front surface of the flange portion 21. The transparent plate 30 is made of high-strength acryl having a light transmittance of more than 96%. A plurality of heat release holes 31 are formed to be spaced apart from each other in a circumferential direction on the transparent plate 30. [43] With reference to FIGs. 2, 5, and 6, the fixing cover 40 includes a side ring portion 41 coupled with the circumference of an outer side of the housing 10 and a front ring portion 42 connected with a front end portion of the side ring portion 41 and disposed at a front surface of the transparent plate 30. Here, coupling recesses 43 are formed at an inner side of the side ring portion 41 and coupled with coupling protrusions 17 formed at the side of the housing 10. The coupling recesses 43 are formed in an 'L' shape so that the coupling protrusions 17 are inserted in a front direction and then rotated in a circumferential direction so as to be coupled to the coupling recesses 43. A scanning hole 44 with a certain size is formed at the center of the front ring portion 42 to allow the light ray which has transmitted through the transparent plate 30 to be scanned in a forward direction. Pressing protrusions 45 with a certain height are formed in a circumferential direction at an inner side of the front ring portion 42 so as to be pressed to the front surface of the transparent plate 30. A water drain hole 46 is formed at a lower portion of the front ring portion 42 in order to externally drain moisture or water generated due to a temperature difference within the vermin ex terminating apparatus 1. [44] With reference to FIGs. 2, 3, and 6, the vermin exterminating apparatus 1 further includes the blocking plate 90 connected to be rotatably at the front surface of the fixing cover 40. The blocking plate 90 blocks a direct ray of light introduced into the housing 10 through the opening 11 and covers the front surface of the transparent plate 30 to protect it as necessary. The blocking plate 90 is a disk type member formed in the same shape as the scanning hole 44 of the fixing cover 40 so as to be matched to the scanning hole 44. A hinge shaft 91 is formed at an upper portion of the blocking plate 90, and a cylindrical shaft receiver 48 is formed at an upper portion of the front surface of the fixing cover 40, into which the hinge shaft 91 is combined to be rotatable at a certain angle. A release recess 49 to be used when the blocking plate 90 is opened is formed at the front ring portion 42 of the fixing cover 40. [45] As for the blocking plate 90 and the fixing cover 40, an opening angle of the blocking plate 90 is set to be within a range of 100'to 160'at the front surface of the fixing cover 40. Namely, when the blocking plate 90 is opened at 100'to 1600, not only the effect of blocking the direct ray of light by the blocking plate 90 can be obtained but also an interference of light scanned through the opening 11 and the blocking plate 90 can be minimized. In addition, the fixing cover 40 includes fixing WO 2008/050934 PCT/KR2006/005485 8 members 92 for fixing the blocking plate 90 covering the front surface of the transparent plate 30. The fixing members 92 is lever type members each with the other end rotatably connected with the front surface of the fixing cover 40 so that one end thereof can move to be caught at a front side of the blocking plate 90. Fixing recesses 93 are formed at the front surface of the blocking plate 90 so that one end portions of the fixing members 92 can be easily inserted therein. Multiple fixing members 92 and fixing recesses 93 are formed to corresponding to each other along a circumferential direction at the fixing cover 40 and the blocking plate 90. [46] With reference to FIGs. 1 and 2, the support 50 includes a clamp 51 fastened to a structure provided at a place where the vermin exterminating apparatus 1, a support rod 52 with one end connected with the clamp 51, and a rotatable connector 53 connected to be rotatable in a vertical direction with the other end of the support rod 52 and connected to be rotatable in a horizontal direction with an upper portion of the housing 10. The clamp 51 can be mounted at the structure by using a plurality of fastening members 56, and one end of the support rod 52 can be integratedly connected with the clamp 51 by welding or the like. [47] With reference to FIGs. 2, 7, and 8, the rotatable connector 53 includes a vertically rotatable part 54 connected to be rotated in a vertical direction at the other end of the support rod 52 by a hinge structure and a horizontally rotatable part 55 combined to be rotatable in a horizontal direction with the vertically rotatable part 54 and mounted on an upper portion of the housing 10. The vertically rotatable part 54 is formed in a disk type and the other end of the support rod 52 is rotatably connected with the upper portion thereof. The horizontally rotatable part 55 is formed to surround edges of the vertically rotatable part 54 and fastened with an upper portion of the housing 10 by a plurality of fastening members. A plurality of position setting protrusions 57 are formed to be spaced apart at uniform intervals along a circumferential direction on one of contact surfaces of the vertically rotatable part 54 and the horizontally rotatable part 55, and a plurality of position setting recesses 58 are formed to correspond to the position setting protrusions 57 on the other of the contact surfaces of the vertically rotatable part 54 and the horizontally rotatable part 55. Accordingly, when the housing 10 is rotated in the horizontal direction, the position setting protrusions 57 are released from the position setting recesses 58 and then inserted into the adjacent different position setting recesses 58, setting a rotation angle of the housing 10. As a matter of course, the position setting recess 58 and the position setting protrusion 57 can be formed on the other end of the support rod 52 and the contact surface of the vertically rotatable part 54. [48] With reference to FIGs. 2, 9, and 10, the light source unit 60 includes a lamp disposed at the center of the front surface of the reflector 20 and generating a light ray WO 2008/050934 PCT/KR2006/005485 9 (referred to as 'disturbing light', hereinafter) with a wavelength that physiologically disturbing vermin. The disturbing light of the light source unit 60 is a visible ray of at least one of blue color and violet color groups. Namely, the light ray of the light source unit 60 can successively generate light rays of various wavelengths from ultraviolet rays to infrared rays, and especially, it relatively intensely generates the light ray of the wavelength band of 380nm to 500nm corresponding to the disturbing light, except for the infrared rays. [49] In particular, the graph in FIG. 9 is a relative spectrum radiation illumination intensity graph with respect to a lamp employed for the light source unit 60 of the vermin exterminating apparatus 1 according to the present invention. The values of the graph were obtained from a relative spectrum radiation illumination intensity testing (test No. 06-10844-001) on the light source unit 60 in the Korea Research Institute of Standards and Science) upon request. The testing was performed under environmental conditions that an AC voltage of 220V was applied at an ambient temperature of 23 0 C±2 0 C and humidity of 55% or below. [50] The disturbing light has such characteristics that it can obtain effects of restraining movement of pigment particles of compound eyes of vermin at night to thus interfere their darkness adaptation, and it can have the same effects for the most vermin. The compound eyes refer to an ommateum of vermin formed as multiple facets gather, and the darkness adaptation refer to adaptation of the compound eyes to darkness as the pigment particles of the compound eyes move. In general, when the pigment particles of the compound eyes of the vermin move for the darkness adaptation, hormone moves by a neurotransmitter to proceed with oviposition, copulation and mutation, etc. In this respect, however, when the movement of pigment particles is restrained by the disturbing light of the light source unit 60, the darkness adaptation of vermin can be interfered, disturbing neurotransmission to thus disturb hormone secretion. Thus, the biological rhythm of vermin is broken so that adult insects can be exterminated and the propagation of the vermin can be prevented by the physiological disturbance such as the oviposition disturbance, copulation disturbance, and mutation disturbance, etc. [51] In addition, because the disturbing light of the light source unit 60 may have the same effects for the most vermin, it can be commonly used for a variety types of vermin. With reference to Table 1 shown below, vermin exterminated by the disturbing light of the light source unit 60 include homoptera, diptera, coleoptera, acarina, het eropteran, thysanoptera, and lepidoptera, etc. [52] Table 1 Types of vermin Types of the order Homoptera Aphid, Trialeurodes, leafhopper WO 2008/050934 PCT/KR2006/005485 10 Diptera Mushroom flies, Liriomyza trifolii, Delia antiqua, Mosquito Coleoptera Henosepilachna vigintioctopunctata, Chrysomelidae Acarina Red spider Heteropteran Hemiptera Thysanoptera Thrips spp. Lepidoptera Butterfly, moth [53] The light source unit 60 may further include a light ray with wavelength (referred to as 'induction light', hereinafter) that induces vermin or a light ray with wavelength (referred to as 'rearing light') that help rear (raise) the crops. When the induction light is intensely generated together with the disturbing light from the light source unit 60, vermin are induced by the induction light and then exterminated by the disturbing light. Thus, the vermin extermination performance of the vermin exterminating apparatus 1 can be further improved. When the rearing light is intensely generated together with the disturbing light from the light source unit 60, rearing of the crops can be accelerated by the rearing light while vermin can be exterminated by the disturbing light. Therefore, the productivity of the crops can be further improved by the vermin exterminating apparatus 1. [54] A visible ray of a red color group is used as the induction light with respect to vermin of diptera, and a visible ray of yellow or orange color group is used as the induction light with respect to vermin of homoptera. With reference to Table 2 shown below, as the rearing light, a light ray with wavelength of at least one of light rays with wavelength band of 315nm to 1,000nm, which does not have a bad influence on the plants, is selectively used. Meanwhile, in Table 2, light rays corresponding to a wavelength band of below 315nm are light rays of ultraviolet group, and with the vermin exterminating apparatus 1, ultraviolet rays generated from the light source unit 60 are mostly blocked by the transparent plate 30, because the ultraviolet rays have the properties that they cannot pass through the transparent plate 30 made of glass or a plastic material as well as quartz. [55] Table 2 Wavelengths of light rays Physiological function of plants 1,000nm Supplying heat 700nm - 1,000nm Accelerating expansion 610nm - 700nm Used for photosynthesis 510nm - 610nm Physiological role 410nm - 510nm Used for photosynthesis (second best following the WO 2008/050934 PCT/KR2006/005485 11 wavelength of 6 1Onm - 700nm) Accelerating formation of flower bud 315nm - 410nm Limiting effect of accelerating formation of flower bud 280nm - 315nm Harmful to most plants below 280nm Fatal influence on plants [56] In order to use the induction light or the rearing light together with the disturbing light by the vermin exterminating apparatus 1, the light source unit 60 can be constructed as a special lamp for simultaneously generating the induction light or the rearing light together with the disturbing light, or the light source unit 60 may include a lamp for generating the disturbing light and a lamp for generating the induction light or the rearing light. Alternatively, a first vermin exterminating apparatus employing the light source unit 60 that generates the disturbing light and a second vermin ex terminating apparatus employing the light source unit 60 that generates the induction light or the rearing light can be combined for use. [57] With reference back to FIG. 2, the controller 70 includes a printed circuit board (PCB) fixedly fastened on the rear surface of the reflector 20 by a fastening member. The controller 70 is connected with the light source unit 60, the sensing unit 80, and the display unit 81 to control the operation of the vermin exterminating apparatus 1. In particular, the controller 70 properly controls the operations of turning on and off the light source unit 60 in order to ensure the vermin extermination performance without exerting a bad influence upon the plants by the light rays from the light source unit 60. [58] The method for controlling the vermin exterminating apparatus and the operation of the vermin exterminating apparatus according to the exemplary embodiment of the present invention constructed as described above will be described as follows. [59] FIG. 11 is a flow chart illustrating the processes of a method for controlling the vermin exterminating apparatus according to the exemplary embodiment of the present invention, and FIGs. 12 and 13 show graphs of experimentation values obtained with respect to agromyzidae and trialeurodes vaporariorum by using the vermin ex terminating apparatus according to one exemplary embodiment of the present invention. [60] First, the method for controlling the vermin exterminating apparatus 1 will now be described with reference to FIG. 11. When power is applied to the vermin ex terminating apparatus 1, the sensing unit 80 of the vermin exterminating apparatus 1 senses light introduced through the first hole portion 14 of the housing 10 to dis criminate the daytime and the night time (S1 and S2). Namely, when the intensity of light sensed by the sensing unit 1 is smaller than a pre-set level, the controller 70 of the WO 2008/050934 PCT/KR2006/005485 12 vermin exterminating apparatus 1 determines that a current time is the night time. If, however, the intensity of light sensed by the sensing unit 80 is not smaller than the pre set level, the controller 70 of the vermin exterminating apparatus 1 determines that the current time is the daytime. At this time, the display unit 81 of the vermin ex terminating apparatus 1 receives power to be turned on and displays an operational state of the vermin exterminating apparatus 1 through the second hole portion 15 of the housing 10. [61] Preferably, the vermin exterminating apparatus 1 is operated at the night time in order to restrain movement of the pigment particles of the insects to thus interfere their darkness adaptation. In general, during the winter season, the vermin exterminating apparatus 1 is operated for 10 hours after sunset, and during the summer season, the vermin exterminating apparatus 1 is operated for 8 hours after sunset. [62] When the controller 70 determines that the current time is the night time, the operation number of a turn-on mode in which the light source unit 60 of the vermin ex terminating apparatus 1 is turned on is initialized and a time measurement value measured by the controller 70 of the vermin exterminating apparatus 1 is also initialized (S3 and S4). And then, the controller 70 measures the operation time of the vermin exterminating apparatus 1 (S5). [63] The vermin exterminating apparatus 1 maintains the turn-off mode in which the light source unit 60 is turned off until a time measurement value of the controller 70 reaches the first pre-set time, and when the time measurement value exceeds the first pre-set time, the turn-on mode in which the light source unit 60 is turned on is performed during the second pre-set time (S6, S7, and S8). In the present exemplary embodiment, the first pre-set time is set as 2 hours and the second pre-set time is set as 10 minutes to 20 minutes. [64] In the turn-on mode, the light source unit 60 is continuously turned on during the second pre-set time, or the light source unit 60 flickers at uniform time intervals during the second pre-set time. The description herein will be limited to the exemplary case where the light source unit 60 is turned on for 0.1 second to 0.25 seconds at intervals of 2 seconds to 5 seconds in the turn-on mode, generating flashes. [65] When the turn-on mode is performed during the second pre-set time, the light source unit 60 is turned off by the controller 70 (S9). When the operation number of the turn-on mode is smaller than a pre-set number, the operation number of the controller increases by 1, the time measurement value of the controller is initialized, and the above-described processes are repeatedly performed (S10 and S11). Namely, the vermin exterminating apparatus 1 repeatedly and alternately performs the turn-off mode in which the light source unit 60 is turned off during the first pre-set time and the turn-on mode in which the light source unit 60 flickers during the second pre-set time.
WO 2008/050934 PCT/KR2006/005485 13 [66] The reason for limitedly operating the tum-on mode of the vermin exterminating apparatus 1 at the night time is to prevent the biological rhythm of the crops from being broken by the light ray of the light source unit 60, besides the generation of the physiological disturbance of vermin by the disturbing light of the light source unit 60. In other words, the light ray of the light source unit 60 can be scanned in the form of flash during the second pre-set time at the intervals of the first pre-set time, so the movement of the pigment particles of vermin can be restrained and its influence upon the plants can be minimized. [67] The turn-on mode and the turn-off mode of the light source unit 60 are repeatedly performed in the above-mentioned manner, and when the operation number reaches the pre-set time or when the controller 70 determines that a current time is the daytime based on a sense value sensed by the sensing unit 80, the operation of the vermin ex terminating apparatus 1 is terminated (S12). [68] Meanwhile, when the disturbing light generated from the light source unit 60 of the vermin exterminating apparatus 1 is irradiated to vermin at the night time, pig mentation is made within the compound eyes of vermin by the disturbing light, re straining movement of the pigment particles of the compound eyes to lead to a failure of the darkness adaptation of vermin, which results in that the biological rhythm of vermin is broken and distorted. Accordingly, with the broken biological rhythm of vermin, the adult insects can be all exterminated in three or four days, and the neuroin formation transmission and material production of vermin and the insect hormone are disturbed to generate physiological disturbance. [69] The physiological disturbance includes the oviposition disturbance, copulation disturbance and mutation disturbance, etc, so that the propagation of vermin can be prevented and a bad influence is made upon vermin which are transformed to prevent the adult insects from breeding. Namely, the vermin exterminating apparatus 1 can implement a reduction of eggs and larvae as well as the adult insects, improving the vermin exterminating performance, and in particular, because the vermin ex terminating apparatus 1 has the same effect for the most vermin, not only a particular insect, it can be commonly used for exterminating vermin. [70] In particular, when the induction light or the rearing light is generated together with the disturbing light from the light source unit 60 of the vermin exterminating apparatus 1, vermin can be induced by the induction light and then exterminated by the light source unit 60, and accordingly, the rearing of the crops can be accelerated by the rearing light. [71] FIGs. 12 and 13 show graphs of experimentation values obtained with respect to agromyzidae and trialeurodes vaporariorum by using the vermin exterminating apparatus 1. The graphs show content obtained through experimentation with respect WO 2008/050934 PCT/KR2006/005485 14 to the performance of the vermin exterminating apparatus 1 at a gerbera farm located at Daedong-myun, Kimhae city. [72] FIG. 12A shows a graph obtained by measuring changes in density of agromyzidae existing at crops in a certain area when the visible ray of a yellow color group detested by agromyzidae was generated from the light source unit 60 of the vermin ex terminating apparatus 1. As shown in the graph, the numbers of agromyzidae was reduced at an early stage of the experimentation due to the visible of the yellow color group but was then increased starting from the middle stage of the experimentation, disregarding the visible ray of the yellow color group. Namely, when the visible ray detested by vermin was generated from the light source unit, the number of vermin was reduced for a short while at the early stage as vermin avoided the light ray, but finally it was increased. [73] FIG. 12B shows a graph obtained by measuring changes in density of agromyzidae existing at crops in a certain area when the visible ray of the blue and violet color groups, namely, the disturbing light, that prevents darkness adaptation of the agromyzidae was generated from the light source unit 60 of the vermin exterminating apparatus 1. As shown in the graph, the number of agromyzidae was continuously reduced due to the disturbing light, starting from an early stage to the last stage of the experimentation. That is, when the disturbing light was generated from the light source unit 60, the number of vermin was continuously reduced due to the physiological disturbance of vermin, ending in extermination of the most vermin. [74] FIG. 12C shows a graph obtained by measuring changes in density of the agromyzidae existing at crops in a certain area when the induction light, a visible ray of a red color group that induces the agromyzidae, as well as the disturbing light in FIG. 12B was generated from the light source unit 60 of the vermin exterminating apparatus 1. As shown in the graph, the number of agromyzidae was continuously reduced due to the disturbing light, starting from an early stage to the last stage of the experimentation, and the reduction speed of the number was increased more than the case of FIG. 12B at the early stage and the middle stage of the experimentation as the agromyzidae was induced by the induction light. Namely, when the induction light was generated together with the disturbing light from the light source unit 60, the effect of inducing vermin was additionally obtained, improving the speed of exterminating vermin by the physiological disturbance of vermin. [75] FIG. 13A shows a graph obtained by measuring changes in density of trialeurodes vaporariorum existing at crops in a certain area when the visible ray of the red color group detested by trialeurodes vaporariorum was generated from the light source unit 60 of the vermin exterminating apparatus 1. As shown in the graph, similarly to content as shown in FIG. 12A, the numbers of trialeurodes vaporariorum was reduced WO 2008/050934 PCT/KR2006/005485 15 at an early stage of the experimentation due to the visible of the red color group but was then increased starting from the middle stage of the experimentation, disregarding the visible ray of the red color group. [76] FIG. 13B shows a graph obtained by measuring changes in density of trialeurodes vaporariorum existing at crops in a certain area when the visible ray of the blue and violet color groups, namely, the disturbing light, that prevents darkness adaptation of the trialeurodes vaporariorum was generated from the light source unit 60 of the vermin exterminating apparatus 1. As shown in the graph, similarly to content shown in FIG. 12B, the number of trialeurodes vaporariorum was continuously reduced due to the disturbing light, starting from an early stage to the last stage of the experi mentation. [77] FIG. 13C shows a graph obtained by measuring changes in density of the tri aleurodes vaporariorum existing at crops in a certain area when the induction light, a visible ray of the yellow color group that induces the agromyzidae, as well as the disturbing light in FIG. 13B was generated from the light source unit 60 of the vermin exterminating apparatus 1. As shown in the graph, similarly to content shown in FIG. 12C, the number of trialeurodes vaporariorum was continuously reduced due to the disturbing light, starting from an early stage to the last stage of the experimentation, and the reduction speed of the number was increased more than the case of FIG. 13B at the early stage and the middle stage of the experimentation as the trialeurodes va porariorum was induced by the induction light. [78] Thus, according to the experimentations as illustrated in FIGs. 12 and 13, vermin was exterminated by the disturbing light scanned from the vermin exterminating apparatus 1, and the vermin exterminating speed of the vermin exterminating apparatus 1 was improved by using the induction light together with the disturbing light. [79] FIG. 14 is an exploded perspective view showing a vermin exterminating apparatus according to another exemplary embodiment of the present invention, and FIG. 15 is a front view of the vermin exterminating apparatus in FIG. 14. [80] In FIG. 14, the same reference numerals as those in the former exemplary embodiment as described above denote the same elements, and a difference of the present exemplary embodiment from the former exemplary embodiment will be described. [81] The difference of a vermin exterminating apparatus 100 in FIG. 14 from the vermin exterminating apparatus 1 is that it includes a lamp 160 that is disposed at a front surface of the reflector 20 and generates a light ray with wavelength that physio logically disturbs vermin, and a filter plate 162 that is disposed at a front side of the lamp 160 and filters a light ray with a particular wavelength among light rays of the lamp 160. Here, the lamp 160 is formed in the same manner as that of the light source WO 2008/050934 PCT/KR2006/005485 16 unit as shown in FIG. 2. [82] The filter plate 162 is a disk type member disposed on a front surface of the transparent plate 30. Heat release holes 164 are formed corresponding to the heat release holes 31 of the transparent plate 30. The blocking plate 90 includes fixing members 92 for fixing the front surface of the transparent plate 30 or the filter plate 162 disposed on the front surface of the transparent plate 30. The fixing members 92 are lever type members each with the other end rotatably connected with the front surface of the fixing cover 40 so that one end thereof can move to be caught at the front side of the filter plate 162. [83] The filter plate 162 is formed to filter a light ray with a particular wavelength among light rays scanned externally through the transparent plate 30. For example, when the filter plate 162 is formed in a red color, a visible ray of the red color group is irradiated through the filter plate 162, and when the filter plate 162 is formed in a yellow color, a visible ray of the yellow color group is irradiated through the filter plate 162. [84] The filter plate 162 may filter the light rays of the lamp 160 to irradiate only of the disturbing light, the induction light and the rearing light. Thus, even when a general 1 ight bulb or an LCD is used as the lamp 160, the vermin exterminating apparatus 100 can scan the disturbing light, the induction light, and the rearing light by the filter plate 160. [85] The foregoing description of the preferred embodiments of the present invention has been presented for the purpose of illustration and description. It is not intended to be exhaustive or to limit the invention to the precise form disclosed, and modifications and variations are possible by a person in the art in light of the above teachings or may be acquired from practice of the invention. [86] That is, the present invention can be applicable to devices with various structures that exterminate vermin by using the visible ray of the blue and violet color groups. In addition, a filter plate on which materials for absorbing only light with a particular wavelength width are coated or a filter plate on which a pattern allowing only light wit h a particular wavelength band to pass therethrough can be used. Industrial Applicability [87] By employing the vermin exterminating apparatus according to the present invention, vermin can be effectively exterminated, the apparatus can be easily managed, and farmers can cultivate the crops which are harmless to people.
