Description

The present invention relates to an insect-proof lamp that emits light having a wavelength that is repelled by pests (hereinafter sometimes referred to as repellent light).

It is already known that the effect of controlling pests can be obtained by irradiating light of a specific wavelength.

For example, Patent Document 1 describes that an LED light source that emits green light is irradiated with an illuminance of 1.5 lux or more to stop night owl activities to reduce crop damage. FIG. 1 shows an illuminating lamp in which an illuminating plate is tilted by about 70 degrees and fixed to a column.

Patent Document 2 describes an LED lamp for a pest control apparatus, which is a combination of a light emitting element that emits blue light having a peak wavelength of 370 nm to 480 nm and a phosphor that emits yellow light having a peak wavelength of 560 to 580 nm. Yes.

Patent Document 3 describes a rod-shaped insect repellent composed of a rectangular housing made of a substrate wired on the back surface so that yellow LEDs are connected in series, and a transparent pipe that houses the tube.

Although the illumination lamp of patent document 1 inclines the illumination board about 70 degree | times and is fixed to the support | pillar, it cannot illuminate the step vicinity of a support | pillar. The pest control apparatus of Patent Document 2 fixes an LED lamp to the ceiling or support of a house and irradiates light toward the bottom surface side. For this reason, the side of the pest control device cannot be illuminated. The rod-shaped insect-proof lamp of Patent Document 3 can illuminate the side face of the insect-proof lamp, but cannot illuminate the bottom face side. As described above, in the conventional insect-proof lamp, repellent light cannot be irradiated on both the bottom surface side and the side surface side of the insect-proof light.

When repellent light is applied, pests such as night moths escape to areas that are not exposed to light. For this reason, the number of pests decreases in the area where the fruit trees and vegetables are irradiated with repellent light. However, if the repellent light is not applied to the foot of the insect-proof light, it becomes a place where the insect pests lay eggs near the foot of the insect-proof light. For this reason, it is difficult to completely keep the pests out of the field. If there are areas where repellent light is difficult to reach, such as in the corners of farm fields, pests may move from the base of the insect-proof light and damage crops such as fruit trees and vegetables.

It is an object of the present invention to provide an insect light that can irradiate repellent light on both the side surface and the bottom surface side of the insect light alone.

An insect light that irradiates light of a wavelength that is repelled by pests, and is composed of an irradiating part for repellent light and a housing that incorporates the irradiating part, and the irradiating part is provided on both the side surface and the bottom surface of the housing. The above problem is solved by the insect repellent lamp configured to irradiate repellent light on both the side surface side and the bottom surface side of the housing. With the insect-proof light, it is possible to irradiate both the side surface side and the bottom surface side of the housing with repellent light, and it is possible to remove pests from the field including the feet of the insect-proof light.

Transparent plates are arranged on the side and bottom of the housing, and by placing the irradiation part inside the transparent plates on the side and bottom, it is possible to irradiate repellent light on both the side and bottom of the housing It is preferable to do. Thereby, it is possible to prevent the irradiation part arranged on the side surface side and the bottom surface side from being stained or damaged.

The transparent plate on the side surface side and the transparent plate on the bottom surface side are preferably configured as a surface in which the transparent surface on the side surface side and the transparent surface on the bottom surface side are continuous. This makes it possible to easily assemble and disassemble the insect-proof lamp by reducing the number of parts.

The transparent plate is preferably composed of a polycarbonate plate. Thereby, it is possible to reduce the ultraviolet transmittance of the transparent plate and prevent the insect-proof lamp from being deteriorated by ultraviolet rays over time. Moreover, since polycarbonate is hard to break, it can be made hard to break when an external force is applied to the transparent plate.

It is preferable that the repelling light irradiating unit is composed of a plurality of LED elements. The LED element has a long life, and the light emission efficiency does not change even at a low temperature. This makes it possible to irradiate stable repellent light over a long period of time.

It is preferable that the side surface side and bottom surface side repellent light irradiation portions include LED elements having a repellent light orientation angle larger than 90 degrees. Accordingly, it is possible to irradiate the repellent light without omission including the area between the bottom surface and the side surface by crossing the repellent light on the bottom surface side and the repellent light on the side surface side.

It is preferable to dispose heat radiating fins on the back surface of the repellent light irradiation portion. This makes it possible to efficiently exhaust heat generated from the irradiation units provided on the side surface and the back surface side.

The housing includes a fixing portion for the support column, one end side connected to the fixing portion, and the other end side supporting the transparent plate and the bracket for supporting the irradiation portion. It is preferable to provide a small window for enabling irradiation of repellent light. By forming the small window using the bracket that supports the irradiation unit, the position of the LED element can be easily determined.

According to the insect-proof lamp of the present invention, it is possible to provide an insect-proof lamp that can irradiate repellent light on both the side face and the bottom face of the insect-proof lamp as a single unit. This makes it possible to remove pests from the field including the feet of insect-proof lights.

The insect-proof lamp 1 of this embodiment irradiates light having a wavelength that is repelled by pests, and irradiates green light having a peak wavelength of 470 nm or more and less than 550 nm from the plurality of repellent light irradiation units 11. The wavelength and color of the repellent light can be changed according to the pests to be controlled. For example, you may use what emits yellow light whose peak wavelength is 550 nm or more and less than 580 nm. You may mix green light and yellow light. Nocturnal pests cease activity when repellent light is applied to areas where pests live at night.

Nocturnal insects cease activity during daylight hours, and become active at night. Although the detailed mechanism by which repellent light stops pest activity at night is unknown, it is speculated that irradiation with repellent light causes nocturnal pests to adapt and stop their activities. By irradiating the repellent light, for example, nocturnal pests such as night owls, mushrooms, and some stink bugs that come to fruit trees and vegetables can be controlled. As shown in FIGS. 1 and 5, the insect-proof lamp 1 according to the present embodiment includes repellent light irradiation units 10 and 11 and a housing 12 in which the irradiation units 10 and 11 are built. Hereinafter, each part will be described.

The insect-proof lamp 1 of this embodiment is provided with irradiation parts 10 and 11 on both the side surface side and the bottom surface side. The side surfaces of the insect-proof lamp 1 are the front, back, right side, and left side of the insect-proof lamp 1. In other words, when a cylinder rising from the bottom surface of the insect-proof lamp 1 is assumed, the irradiation units 10 and 11 are provided on both the side surface side of the column and the bottom surface side of the column. In the insect-proof lamp 1 of this embodiment, a right side surface, a left side surface, a front surface, and a back surface are referred to as a side surface side.

The irradiation unit 10 on the side surface side is formed by fixing a plurality of LED light emitting elements 31 to an electronic substrate 30 of a predetermined size, and includes a total of 32 LED light emitting elements per electronic substrate. The irradiation unit 11 on the bottom side is formed by fixing a plurality of LED light emitting elements 33 to an electronic substrate 32 having a smaller area than the electronic substrate 30, and includes a total of four LED light emitting elements 32 per electronic substrate. The irradiation units 10 and 11 on the side surface side and the bottom surface side are fixed and radiated heat while being in contact with the base side of the radiation fin 38. As shown in FIGS. 8 and 9, the bottom surface side irradiation unit 11 is provided with a fixed block 34 on the base side of the radiation fin 38, and the electronic substrate 32 of the irradiation unit 11 contacts the fixed block 34. So that it is fixed. The fixed block 34 is made of aluminum having a high thermal conductivity. The side surface and bottom surface irradiation units 10 and 11 are fixed to the heat radiation fins 38 by screws 35 and 36.

As shown in FIGS. 1 to 7, the housing 12 has a fixing portion 13 for the support column, a plurality of transparent plates 14, one end connected to the fixing portion 13, and the other end connected to the transparent plate 14 and the irradiation portion 11. A plurality of brackets 15 and 16 for supporting, and a plurality of angles 17 for fixing the transparent plate 14 are provided. The fixed portion 13 is constituted by a cylindrical member provided with a flat-side flange 18 and a bottom-side flange 19. As shown in FIG. 9, the support 45 is fitted into the cylinder from the lower end side, and the fixing portion 13 is fixed to the support 45. The support | pillar 45 is fixed to the ground 46 by appropriate means, such as inserting in the ground 46 of a farm field. The flanges 18 and 19 are plate-like members and intersect substantially perpendicular to the cylinder. A plurality of bent portions 20 and 21 are provided on the outer edge portions of the flange 18 on the flat surface side and the flange 19 on the bottom surface side, respectively. Similarly, bent portions 22 and 23 are provided in the extended portions of the bracket 15 on the flat surface side and the bracket 16 on the bottom surface side, respectively. As shown in FIG. 7, the bent portion 21 of the bottom surface side flange 19 is connected to each other by screwing in a state of being in contact with the bent portion 23 arranged at one end of the bottom surface side bracket 16. Similarly, the bent portion 20 of the flat side flange 18 is connected to each other by screwing in a state of being in contact with the bent portion 22 disposed at one end of the flat side bracket 15. The plane side bent portions 20 and 22 are bent to the bottom side. In FIG. 5, the bent portions 20 and 22 are indicated by broken lines.

The bracket 15 on the plane side includes a bent portion 22 disposed on one end side, a support portion 24 disposed on the other end side, and an arm 26 that connects the bent portion 22 and the support portion 24. Similarly, the bracket 16 on the bottom side includes a bent portion 23 disposed on one end side, a support portion 25 disposed on the other end side, and an arm 27 that connects the bent portion 23 and the support portion 25. Become. The support portions 24 and 25 have a shape wider than the arms 26 and 27. The brackets 15 and 16 are plate-shaped members. As described above, the bent portions 22 and 23 on one end side of the bracket are fixed to the bent portions 20 and 21 of the flanges 18 and 19, respectively. The brackets 15 and 16 are positioned on the same plane as the flanges 18 and 19 on the flat surface side and the bottom surface side in a state where the brackets 15 and 16 are assembled to the fixing portion 13. The support portion 25 of the bracket 16 on the bottom surface side is cut out into a rectangular shape, thereby forming a small window 28. The flat bracket 15 is not provided with a notch.

The angles 17 are members disposed at both ends of the transparent plate 14 along the extending direction of the fixed portion 13 and are L-shaped plate-like members having substantially right-angled corners. The transparent plate 14 is placed on the base side of the radiation fin 38 in a state where the irradiation parts 10 and 11 on the side surface and bottom surface side are fixed to the radiation fin 38. In a state where the left and right end portions of the transparent plate 14 are covered with the angle 17, the angle 17 and the heat radiating fins 38 are stopped by a plurality of screws 37.

As shown in FIG. 7, the heat radiation fin 38 includes a block-shaped base portion 39 and a plurality of fins 40 protruding from the base portion 39. A block 48 provided with screw holes is fixed to the left and right ends of the base end side of the radiating fin 38. A screw 37 is screwed into the screw hole of the block 48 to fix the angle 17 described above. The upper end surface of the base end portion of the heat radiating fin 38 is fixed to the bracket 15 on the flat surface side by being fastened with a screw 42 while being in contact with the support portion 24 of the bracket 15 on the flat surface side. The lower end surface of the base end portion of the heat radiation fin 38 is fixed to the bracket 16 on the bottom surface side by being fastened with a screw 42 in a state of being in contact with the support portion 25 of the bracket 16 on the bottom surface side. For this reason, the radiation fin 38 is fixed to the fixing portion 13 while being sandwiched between the brackets 15 and 16 on the flat surface side and the bottom surface side. As shown in FIG. 7 and FIG. 8, the bottom surface side bracket 16 and the radiation fins 39 are provided with the bottom surface side transparent plate 14 interposed between the irradiation portion 11 and the support portion 25 of the bracket 16. The lower end surface of the screw is stopped by a screw 42. The transparent plate 14 on the bottom side has the same width as the bottom side support portion 25 when viewed from the bottom, so that the transparent plate 14 does not rattle when screwed. The radiating fins 38 are made of aluminum having a high thermal conductivity.

In the space 43 between the irradiation unit 10 on the side surface side and the irradiation unit 11 on the bottom surface side, control devices (not shown) of the irradiation units 10 and 11 are stored. Issuing patterns such as blinking, continuous light emission, light emission intensity, or timer control such as turn-off or lighting is performed by the control device. Since the space 43 is also covered with the transparent plate 14, the controller 44 is prevented from being visually recognized by covering it with the seal 44.

The transparent plate 14 on the side surface side and the transparent plate 14 on the bottom surface side are configured as continuous surfaces as shown in FIGS. 8 and 9. In other words, the transparent plate 14 on the side surface side and the transparent plate 14 on the bottom surface side are composed of one member. Thereby, the assembly of an insect-proof lamp can be made easy by reducing the number of members. For example, when assembling the insect-proof lamp 1, first, the radiation fin 38, the irradiation units 10, 11, and the transparent plate 14 are integrated, and this is placed between the bottom-side bracket 16 and the flat-side bracket 15. It fixes with the screw 42 in the clamped state. At this time, since the bottom-side transparent plate 14 and the side-side transparent plate 14 are configured as a continuous surface, the side-side transparent plate 14 can be prevented from falling during assembly. Furthermore, the gap between the transparent plate 14 on the side surface side and the transparent plate 14 on the bottom surface side can be eliminated by configuring them as continuous surfaces. Thereby, it is possible to prevent dust and water droplets from entering the housing from the gap. The transparent plate 14 on the side surface side and the transparent plate 14 on the bottom surface side may be formed integrally, or may be formed separately and joined together with an adhesive or the like.

In the insect-proof light 1 of this embodiment, the transparent board is distribute | arranged to the side surface side and bottom face side of a housing | casing, and the irradiation parts 10 and 11 are arrange | positioned inside both the transparent boards 14 of a side surface and a bottom face. For this reason, it is possible to prevent the irradiation units 10 and 11 from being soiled or damaged due to collision of bird droppings, wind and rain, or an object. When the transparent plates 10 and 11 become dirty, the dirt can be easily removed by wiping the surface or the like. Even if the transparent plate 14 on the side surface and the bottom surface side is scratched and the transmission of the repellent light is hindered, it can be easily replaced with a new transparent plate 14. In the insect-proof lamp 1 of this embodiment, since the transparent plates 14 on the side surface side and the bottom surface side are continuous, the wiping operation can be easily performed, and the damaged transparent plate 14 can be easily replaced. .

Both the bottom and side transparent plates 14 are made of a polycarbonate plate. For this reason, it is possible to prevent the transparent plate 14 from cracking when a large force is applied to the transparent plate 14 by dropping the insect-proof lamp or the like when it is attached to the column. Moreover, since polycarbonate cuts almost 100% of ultraviolet rays, it is possible to prevent the electronic substrates, LED elements, adhesives, and the like constituting the irradiation units 10 and 11 from being deteriorated by ultraviolet rays. This makes it possible to extend the service life of the insect-proof lamp.

The irradiation units 10 and 11 on the side surface side and the bottom surface side preferably use LED elements having a light distribution angle of repellent light larger than 90 degrees. In the insect-proof lamp 1 of this embodiment, the orientation angles of the LED elements on the bottom surface side and the side surface side are all 120 degrees. In FIG. 12, the spread of repellent light of an LED element having an orientation angle of 90 degrees is indicated by a broken line, and the spread of repellent light of an LED element having an orientation angle of 120 degrees is indicated by a solid line. FIG. 12 shows a state in which only the bottom LED element on the side surface side and the LED element on the bottom surface side emit light for convenience. As shown by the broken line, when the orientation angle is 90 degrees, a region where no repellent light is irradiated is generated in the middle between the side surface and the bottom surface. On the other hand, when the orientation angle is 120 degrees as shown by the solid line, the repellent light on the side surface and the bottom surface overlaps around the middle between the side surface and the bottom surface, and the repelling occurs around the middle between the side surface and the bottom surface. The irradiation intensity of light can be increased. Accordingly, it is possible to control the pests by irradiating the insect repellent light 1 from the foot of the insect-proof lamp 1 in an obliquely upward direction.

When the irradiation unit 10 on the side surface side and the irradiation unit 11 on the bottom surface side, the radiation fin 38, the transparent plate 14 on the side surface side, and the transparent plate 14 on the bottom surface side are used as illumination units, the number of illumination units is 3 or more. Preferably there is. As a result, it is possible to irradiate the side surface without repelling light. The number of illumination units of the insect-proof lamp of this embodiment is four. The illumination unit may be circular in plan view. That is, the transparent plate on the plane side and the irradiation unit on the side surface composed of the LED element and the electronic substrate may be configured in a circle in plan view.

The fixing unit 13 and the irradiation units 10 and 11 are connected to each other via the arms 26 and 27. As shown in FIGS. 5 to 7, the vents between the fins 40 and the fixing portion 13 are formed by making the protruding amounts of the arms 26 and 27 larger than the protruding amounts of the fins 40 in plan view or bottom view. 47 can be provided. The vent 47 communicates with the outside of the housing, and allows outside air to pass through. Thereby, the thermal radiation efficiency of the thermal radiation fin 38 can be raised.

The radiating fins 38 are fixed to the brackets 15 and 16 so as to protrude toward the fixing portion 13. For this reason, in the state which attached the brackets 15 and 16 to the fixing | fixed part 13, the radiation fin 38 is not visually recognized from the side surface direction of a housing | casing. Thereby, the insect-proof lamp 1 looks like a box. Since the fins 40 are not exposed to the outside, it is preferable that the heat dissipating fins 39 are not easily soiled or damaged. Even when it is dirty, it is like a box, so it can be easily removed by wiping it.

As described above, the support portion 25 of the bracket 16 on the bottom side is cut out to form a small window 28. The side and bottom transparent plates 14 are configured as continuous surfaces. When the bracket 16 on the bottom side, the radiation fins 38, the irradiation parts 10 and 11 on the side and bottom sides, and the continuous transparent plate 14 are assembled, the LED element can be easily positioned at a position where the LED element can be seen from the small window. Is possible. That is, it is not necessary to perform a particularly difficult operation when fixing the LED element at a position where the LED element can be seen from the small window during assembly.

According to the insect-proof lamp 1 of this embodiment, as shown in FIG. 10, it is possible to irradiate repellent light over a wide range from an obliquely upper part of the insect-proof lamp to immediately below the insect-proof lamp. In conventional insect-proof lamps, places where repellent light does not reach, such as directly under the insect-proof lamps, have become the place where insects live and cause the insects to propagate. If the insect-proof light 1 of this embodiment is used, it will become possible to exclude a pest from just under an insect-proof light. The repellent light itself has no effect on killing the pest eggs. However, if the insect repellent lamp 1 of this embodiment is continuously used, it is possible to keep the hatched insects out of the field. For example, in the case of a night cocoon, an egg, a larva, a moth, an adult, and an egg are defined as one life cycle. The use of insect proof lights continuously over a period of 2 to 3 life cycles can greatly reduce the number of night moths inhabiting the field.
