Description

The present invention relates to an insecticidal device using blue light, and more specifically, it is installed in a mechanical drive unit or a switch panel in a food or drink factory, a pharmaceutical factory, or the like to kill insects. It relates to an insecticidal device that uses blue light to prevent its occurrence.

Some insects cause various harms to humans and livestock as pests. For example, agricultural pests cause serious problems in the agricultural field such as a decrease in crop production and the spread of plant diseases, and sanitary pests transmit pathogens such as viruses, bacteria, and protozoans, and are very hygienic. Affect. Therefore, efficient control of pests is an important agricultural and hygienic issue.

Conventionally, chemical control methods using chemical preparations have been mainly used for pest control, but pest control using chemical control methods involves the emergence of drug-resistant individuals, environmental pollution, and residue on crops. It becomes a problem. Therefore, in recent years, an optical control method using light has been adopted as one of the alternative control methods having high safety and less impact on the environment.

As this optical control method, for example, a method of attracting and killing insects with ultraviolet light to blue light by utilizing the phototaxis of insects is known. This method is a simple and relatively inexpensive method that has been used for a long time as a control method for agricultural pests, such as a trap light, but since many of the attracted individuals are adults with flying ability, eggs and eggs are used. No fundamental control can be expected to eliminate larvae.

Therefore, as an alternative optical control method, a device has been proposed that suppresses the movement of pigment particles in compound eyes by irradiating insects with long-wavelength ultraviolet rays to short-wavelength visible light of 380 to 500 nm (Patent Document 1). .. This device attempts to disrupt the insect's ecological rhythm by disturbing the light-dark adaptation of the insect by irradiating the visible light and disturbing the nerve transmission to disrupt the hormone secretion, thereby killing the adults. In addition, it is said that the reproduction of pests can be prevented by physiological disturbances such as spawning disturbance, mating disturbance, and mutation disturbance.

However, Patent Document 1 does not describe data demonstrating the effect of the present invention, and the control target that acts directly is limited to adults, and eggs and some that do not have compound eyes. Has no effect on larvae. Furthermore, the light-adapting and dark-adapting properties of compound eyes vary greatly depending on the type of insect. For example, in the case of nocturnal moths, the light that causes light adaptation is yellow light to green light of 500 to 590 nm, and the effect is weak in purple light to blue light of 380 to 500 nm. Therefore, there is a problem that it is not possible to disturb various nocturnal insects at a specific wavelength range, and there is also a problem that such confusion due to light-dark adaptation has no effect on diurnal insects. is there.

In order to solve these problems, a light source for pest control that emits light of a specific wavelength in the wavelength range of 400 to 500 nm is targeted for pest eggs, larvae, or pupae, 7 × 10 ¹⁷ feet · m- ² ·. There is a proposal of a pest control device configured to be capable of irradiating with a light intensity of s- ¹ or higher (Patent Document 2). This device was developed based on the finding that when a specific short wavelength visible light is applied to an egg, larva, or pupa of a target pest, it can inhibit the metamorphosis of the target pest and kill the insect.

A mode for carrying out the present invention will be described with reference to the accompanying drawings. The insecticidal device using blue light according to the present invention comprises a plurality of blue LED units 1 in which a large number of blue irradiation LEDs 3 are arranged in a row in a long housing 2 and connected in series at appropriate intervals. It is a thing. The blue LED unit 1 has, for example, a waterproof structure having a length of 260 mm, a width of 40 mm, and a height of 35 mm, and the blue LED units 1 are connected to each other via a cord 4 having an appropriate length. ..

As an example, three blue LED units 1 equipped with eight blue irradiation LEDs 3 of eight lights are connected via a cord 4 having a length of about 150 mm, and are connected to a DC power supply or an AC power supply. (See Figures 1 and 2). The blue irradiation LED 3 used here emits blue light, which is short-wavelength visible light having a wavelength peak in the wavelength range of 400 to 500 nm. If necessary, a light intensity adjusting unit, a light intensity adjusting device, a wavelength adjusting device, a wavelength selection filter, a switch, a battery, and the like are appropriately incorporated in the housing 2.

Since the insecticidal device using blue light according to the present invention mainly targets pests living in a relatively dark place not directly exposed to sunlight, the blue LED unit 1 in which eight blue irradiation LEDs 3 are juxtaposed is used. , 7 × 10 ¹⁷ photos ・ m- ²・ s ^-1 or more light intensity irradiation is sufficient. In order to achieve this condition, for example, three blue LED units 1 in which eight blue irradiation LEDs 3 are juxtaposed may be used.

The insecticidal device using blue light according to the present invention was developed on the assumption that it is used in a narrow and difficult-to-clean place such as a mechanical drive unit or a switchboard in a food and beverage factory or a pharmaceutical factory. As a matter of fact, since the above three blue LED units 1 are separated from each other in a state of being connected by the cord 4, there is freedom in the arrangement mode thereof, and the arrangement according to the situation of the installation location is as follows. There is an advantage that it can be an embodiment.

1 to 3 show an arrangement example in which there is a relatively large space on the inner bottom surface of the gantry case of the equipment to be arranged. In that case, the three blue LED units 1 are brought into contact with each other. (See FIG. 1) or at appropriate intervals (see FIG. 2) and arranged side by side. In the illustrated example, all three blue LED units 1 are oriented upward (one-dimensional irradiation), but the blue LED units 1 on one side or both sides may be oriented sideways (two-dimensional). Irradiation).

FIG. 4 shows an arrangement example in the case of arranging in an L shape on the inner bottom surface of the gantry case of the device. Also in this arrangement example, all three blue LED units 1 may be turned upward (see FIG. 4), or some of them may be turned sideways. Further, FIG. 5 shows an arrangement example in which, for example, the blue LED unit 1 is installed on the inner bottom surface and the inner side surface of the gantry case of the device. In the illustrated example, one blue LED unit 1 is shown. Is installed on the inner wall surface, and two blue LED units 1 are arranged in a straight line on the inner bottom surface. Also in this arrangement example, some blue LED units 1 may be turned sideways. An adhesive, double-sided tape, a magnet, or the like is used to fix the arrangement of the blue LED unit 1, if necessary.

The insecticidal device using blue light according to the present invention may be used in an environment where powder is easily scattered, such as a flour mill or a food factory that handles powder such as wheat flour. In such an environment, powder and dust adhere to the blue irradiation LED3, the irradiation intensity of blue light to the target portion is reduced, and the insecticidal action of the blue irradiation LED3 and its generation prevention action are hindered. May be done. Therefore, in one embodiment, the plurality of blue LED units 1 are arranged in the translucent case 5 made of translucent resin.

FIGS. 6 and 7 show the embodiment, and the translucent case 5 shown therein has a circular shape, and the base 6 equipped with the rotation drive mechanism and a plurality of blue LEDs arranged on the base 6 are shown. It comprises a unit 1 and a transparent cover 7 that covers a plurality of blue LED units 1 on the base 6. In the case of this configuration, the blue light emitted from the blue LED unit 1 irradiates the target portion through the transparent cover 7.

The drive shaft 8 of the rotary drive mechanism projects from the center of the upper surface of the base 6, further penetrates through the transparent cover 7, extends, and the wiper 9 is attached to the tip thereof. The wiper 9 has a rod shape that can wipe at least the upper surface of the transparent cover 7, but is preferably an L-shape so that the wiper 9 can be wiped from the upper surface to the side surface of the transparent cover 7. A wiping member 10 made of resin, rubber, fiber, or the like is provided at a portion of the wiper 9 in contact with the transparent cover 7.

A plurality of blue LED units 1 arranged on the base 6 are arranged in a triangular shape, for example. That is, three or six connected blue LED units 1 are arranged in a triangular shape. When six blue LED units 1 are used, the three units forming the inner triangle may be turned upward, and the three units forming the outer triangle may be turned sideways. In such a case, relatively uniform irradiation over a wide area becomes possible.

In the case of this embodiment, the wiper 9 is rotationally driven via the drive shaft 8 by continuously, intermittently, or periodically operating the rotary drive mechanism in the base 6. Thus, the powder and dust adhering from the upper surface to the side surface of the transparent cover 7 are wiped off by the wiper 9 at any time, so that the powder and dust adhere to the transparent cover 7 from the upper surface to the side surface, and the irradiation intensity of blue light to the target portion is obtained. There is no possibility that the blue irradiation LED3 will hinder the insecticidal action of insects and the action of preventing their occurrence.

As described above, in the case of the insecticidal device using blue light according to the present invention, since the plurality of blue LED units 1 are separated from each other in a state of being connected by the cord 4, the arrangement mode is free. There is sex. Therefore, it is suitable for use in narrow and difficult-to-clean places such as machine drive units and switchboards in food and beverage factories and pharmaceutical factories, and it should be installed in an arrangement according to the situation of the installation place. As a result, it is possible to kill the insects that are occurring at the installation location and effectively prevent their occurrence, and further, measures are taken to prevent the attenuation of the irradiation amount from the blue LED unit 1 due to dust and the like. The industrial availability is great.
