Description

  TECHNICAL FIELD The present invention relates to a method for producing a reference edge and an insect trap using the method. More specifically, for example, a food factory, a pharmaceutical factory, a container packaging factory, etc. The present invention relates to an insect trap installed in a factory or facility that needs to be blocked, and a method for producing a reference edge having a high attracting effect for insects applied to the trap.

  As an insect trap, for example, an attracting light generator is known in which an attracting light is disposed in a semicircular case having an adhesive surface on the inner surface, and in order to further enhance the attracting effect ( Japanese Patent No. 2599101). In this case, a BL lamp is generally used as the light source. However, since the BL lamp consumes a large amount of power and has a short lifetime, it is considered that the attraction effect is lower than that of the BL lamp. There is a growing demand for using LEDs that have the advantage of low consumption and long life.

  By the way, conventionally, in a light emitting device including a first light source that emits light in a first wavelength region and a second light source that emits light in a second wavelength region different from the first wavelength region, these first light sources are provided. There has been proposed an attracting device that utilizes the attraction of insects such as stink bugs at the boundary between the first light source and the second light source (WO2013 / 042743A1).

  The attracting device according to this proposal forms a vertical edge along a boundary line of a light transmitting plate by juxtaposing two light transmitting plates having different colors on the front surface of a housing containing a light emitting means. Is. As the material for the light transmitting plate, a material that mainly transmits ultraviolet light having a wavelength of about 370 nm and a material that mainly transmits green light having a wavelength of about 520 nm are used.

  The invention of this attracting device is that when an insect is attracted by light, it is not simply attracted to light or a specific wavelength, but rather is attracted to the contrast (edge part) of the wavelength of the light emitted by the light source. It was made based on the knowledge of. In addition, the edge part of light here means the boundary part of the part which is shining, and the part which is not shining around when it is single light, and when it is two or more kinds of light, , Each means a different light boundary.

  In the case of this attracting device, it attracts pests more efficiently than when using a light source such as a mercury lamp that emits a lot of light having a wavelength of 300 to 600 nm or an LED that emits a lot of light having a relatively short wavelength. It is supposed to be possible. However, the edge in that case is created by juxtaposing two translucent plates of different colors, so that the brightness and the like are caused by the light distribution of the light source and the uniformity of the light projection plate. There is a problem that a problem occurs and it is difficult to clearly create an edge.

WO2013 / 042743A1

  As described above, in the case of an attracting device that has been proposed in the past, since the edge is created by juxtaposing two light-transmitting plates of different colors, the light distribution and light projection of the light source Due to the uniformity of the plate, there are problems such as brightness, and it is difficult to clearly create an edge.

  Therefore, an object of the present invention is to provide a method for creating a quoted edge that can clearly create an edge that is a boundary portion of different light, and an insect trap using the method.

  In the invention according to claim 1 for solving the above-described problem, LEDs having different emission colors are arranged on both sides of a diffusion plate having a triangular cross section in the middle, and one of the LEDs is arranged on one side of the diffusion plate. By irradiating and reflecting the light toward the slope of the diffuser, and irradiating and reflecting the other LED toward the slope of the other side of the diffuser plate, light is reflected along the ridge line of the triangular portion of the diffuser plate. This is a method for creating a quoted edge, which is characterized in that an edge that is a boundary portion of the image is created.

  Further, the invention according to claim 2 for solving the above-mentioned problem is an insect trap in which a light-transmitting resin plate is arranged in the front opening, and an illuminating means is installed in a housing on which an adhesive sheet is arranged. A diffusion plate raised in a triangular shape along the horizontal or vertical line of the intermediate portion on the inner back surface of the casing, and disposed on one inclined surface of the triangular portion of the diffusion plate By arranging the LEDs for ultraviolet light emission toward the other side and arranging the LEDs for light emission of other colors toward the other inclined surface and simultaneously irradiating them, it is a boundary portion of light along the ridge line of the triangular portion of the diffusion plate An insect trap characterized in that the edge can be created.

  In one embodiment, the other color light emitting LED is a green LED. In addition, the area of the irradiation area by the ultraviolet light emitting LED in the diffusion plate is set to be the same as or larger than the area of the irradiation area by the other color light emitting LED, and the ultraviolet light of the diffusion board in the adhesive sheet. The peripheral edge portion of the irradiation area corresponding portion by the light emitting LED and the other color light emitting LED protrudes outward.

  In one embodiment, the surface of the diffusion plate is blasted, and one or both surfaces of the translucent resin plate are blasted. The diffusing plate is subjected to a light diffusing process by kneading a diffusible substance during molding. The housing is preferably matte black.

  The present invention is as described above, and the irradiation area is divided into two by the triangular portion of the diffusion plate, and the ultraviolet light and other color light from the LED are reflected on the slopes on both sides of the diffusion plate and directed to the front side. By blasting the diffuser plate and the translucent resin plate, the diffusibility of reflected light is enhanced, so that the color is clearly divided between the ultraviolet area and the other color area without causing color mixing. In addition, there is an effect that an edge which is a boundary of light is created beautifully. In addition, since an LED is used as a light source, the power consumption is low, and the edge of light having a high attracting action is neatly created, so that the insect catching rate can be improved.

It is a perspective view which shows the structure of the insect trap which concerns on this invention. It is a longitudinal cross-sectional view which shows the structure of the insect trap which concerns on this invention. It is a graph which shows the spectrum distribution of the light source in the insect trap which concerns on this invention.

  Embodiments for carrying out the present invention will be described with reference to the drawings. In the cited edge producing method according to the present invention, LEDs having different emission colors are arranged on both sides of a diffuser plate having a triangular cross section at the center, and one of the LEDs is directed to a slope on one side of the diffuser plate. By irradiating and reflecting the other LED toward the inclined surface on the other side of the diffusion plate and reflecting it, along the ridge line of the triangular portion of the diffusion plate, at the boundary of light It is characterized in that an edge is created.

  Moreover, the insect trap which concerns on this invention utilizes the said reference | invitation edge production method, Comprising: As FIG.1 and FIG.2 shows, a translucent resin board is fundamentally provided in the front opening part 2. As shown in FIG. The ultraviolet light transmitting acrylic plates 3 and 4 are arranged, and the illumination means is installed in the casing 1 on which the adhesive sheet 5 is arranged. On the outer surface of the housing 1, a switch 21, a sound volume 23, a hanging hook 24, and the like are disposed. In addition, an attracting sound generating speaker 22 is installed at the upper part of the front surface. Further, although not shown, a light amount adjusting switch or the like is installed at an appropriate place. The housing 1 is preferably matte black. In such a case, the reflected light of the housing 1 can be suppressed in a bright environment, and improvement in insect trapping efficiency can be expected.

  In the illustrated example, two ultraviolet light transmissive acrylic plates 3 and 4 are fitted to the front opening 2. Preferably, the ultraviolet light-transmitting acrylic plates 3 and 4 are subjected to sandblasting (blast processing portion 10) to improve the light distribution by increasing the diffusibility of transmitted light. The blasting process is performed on, for example, the inner surface of the outer ultraviolet light-transmitting acrylic plate 3 and both surfaces of the inner ultraviolet light-transmitting acrylic plate 4.

  The pressure-sensitive adhesive sheet 5 is obtained by applying a pressure-sensitive adhesive to a transparent resin film, and one or a plurality of guides 6 for holding the side portions of the pressure-sensitive adhesive sheet 5 are provided on both sides of the front frame of the housing 1. The pressure-sensitive adhesive sheet 5 is inserted along the guide 6 from above, and its lower side is pushed in a curved state toward the lower receiving groove 7 provided so as to extend forward from the lower front side of the housing 1. To lock. Further, the upper side is locked by an upper receiving groove 8 installed along the upper side of the front surface of the housing 1.

  On the back surface of the inner surface of the housing 1, a diffuser plate 11 is disposed in which a center line corresponding part in the horizontal direction or the vertical direction (in the illustrated example, the horizontal direction) is raised in a triangular shape along the center line. The diffusion plate 11 in the illustrated example is formed by symmetrically attaching two members, but can be formed by bending a single plate. The slopes 12 and 13 on both sides of the diffusing plate 11 are usually flat slopes, but may be curved.

  Typically, the diffusion plate 11 is an aluminum plate, and in one embodiment, the front side thereof is subjected to a blasting process for improving the diffusibility of reflected light (blast processing unit 16). In another embodiment, instead of the blasting process, or the blasting process is performed, a light diffusing material is kneaded into the diffusion plate 11 at the time of molding. For example, an organic polymer powder (bead) is used as the light diffusing substance, and this is mixed into the molten resin during molding and uniformly dispersed. Further, instead of the above light diffusion method, it is conceivable to attach a light diffusive film to the diffusion plate 11. Note that the diffuser plate 11 is formed with a bent portion 17 from the lower end of the slope of the triangular portion to both ends as necessary, so that the reflected light is directed forward.

  An appropriate number of ultraviolet light emitting LEDs 14 are arranged on the top surface of the housing 1 so as to face one inclined surface 12 of the diffusion plate 11, and the housing faces the other inclined surface 13 of the diffusion plate 11. Appropriate numbers of LEDs 15 of other colors are arranged on the bottom surface of one. In a preferred embodiment, the LED 15 is a green light emitting LED. In use, the LED 14 and the LED 15 emit light simultaneously.

  In the illustrated example, the edge 20 is created in the horizontal direction, but the edge 20 may be created in the vertical direction. Moreover, LED15 may be made into red, yellow, etc. according to the kind of insect. As an example, the housing 1 has a width of 344 mm, a height of 348 mm, and a depth of 145 mm, and the size of the illumination unit (front opening 2) is 200 mm long and 300 mm wide. In this case, five LEDs 14 and 15 are arranged in order to increase the overlap of light.

In the insect trap configured as described above, when the ultraviolet light emitting LED 14 and the green light emitting LED 15 are used, in the ultraviolet area 18 that is the irradiation region by the ultraviolet light emitting LED 14 and the green area 19 that is the irradiation region by the green light emitting LED 15, When adjusting to 1.0 × 10 ¹³ photons / cm ² / sec, a confirmation test was performed to determine whether or not wavelength mixing was observed. In this test, with the central portion of each of the ultraviolet area 18 and the green area 19 with the adhesive sheet 5 removed, the sensor of the spectroscope (Asahi Spectroscopy, HSU-100S) is brought into contact with the light emitting surface of the diffuser plate 11. The measurement was performed by measuring the amount of light in the wavelength band of 250 to 1000 nm.

As a result of the above test, the ultraviolet and green peak wavelengths were 367 nm and 529 nm, respectively, and no significant change in wavelength due to the structure was observed (see the spectrum distribution diagram of FIG. 3). In the measurement of the ultraviolet area 18, the light amount of 330 to 430 nm (0.97 × 10 ¹³ photons / cm ² / sec) in the total light amount (0.98 × 10 ¹³ photons / cm ² / sec) of 250 to 1000 nm. ) Accounted for 96.7%. The total amount ^{(0.97 × 10 13 photons / cm} 2 / sec) of 450~650nm in quantity ^{(0.96 × 10 13 photons / cm} 2 / sec) ratio of the green area 19 98.9% Met.

On the other hand, the ratio occupied by the light amount of 450 to 650 nm in the ultraviolet area 18 (0.006 × 10 ¹³ photons / cm ² / sec) is 0.6%, and the light amount of 330 to 430 nm in the green area 19 (0.003 × 10 ¹³ photons / cm ² / sec) accounted for 0.3%, and it was confirmed that almost no color mixing occurred in the respective areas 18 and 19.

  In this way, almost no color mixing occurs between the ultraviolet area 18 and the green area 19 because the irradiation area is divided into two by the triangular portion of the diffusion plate 11, and the ultraviolet light from the LED 14 and the green light from the LED 15 are separated. Reflected by the inclined surfaces 12 and 13 on both sides of the diffusing plate 11 toward the front side, and the diffusing plate 11 and the ultraviolet light transmitting acrylic plates 3 and 4 are subjected to blasting to diffuse the reflected light. This is due to a synergistic effect such as an increase in the properties. As a result of the fact that almost no color mixing occurs between the ultraviolet area 18 and the green area 19, the boundary 20 becomes clear and the edge 20 is created.

  In the illustrated example, the areas of the ultraviolet area 18 and the green area 19 are substantially the same, but the ultraviolet area 18 that is an irradiation area by the ultraviolet light emitting LED 15 having an attracting effect is larger than the green area 19. A configuration in which the triangular portions are arranged so as to be shifted is also conceivable. Moreover, since it is also considered that an insect gathers in the peripheral part of the ultraviolet area 18 and the green area 19, the peripheral part of the ultraviolet area 18 corresponding part and the green area 19 corresponding part in the adhesive sheet 5 is made to project outward. It is also conceivable to increase the insect trapping efficiency.

  The insect trap according to the present invention is used by installing it at a place where insect trapping is necessary, for example, by using a hanging hook 24 as in the case of a general insect trap. In the case of this insect trap, as described above, since the edge 20 having a strong action of attracting insects is clearly created, the attracting action is strong, and a significant improvement in the catching efficiency can be expected.

  Although the invention has been described in certain preferred embodiments in some detail, it will be appreciated that a wide variety of embodiments can be constructed without departing from the spirit and scope of the invention. Accordingly, the invention is not limited to the specific embodiments except as limited in the appended claims.
