Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention is applicable to pest-killing lights that attract and capture pests that harm agricultural crops with the light of a luminous body, and moth-proofing lights that eliminate pests with the light of a luminous body. Concerning the lighting method of exterminating lights.

[Background of the invention]

In recent years, the use of agricultural chemicals to exterminate pests that harm agricultural crops has become a social problem such as environmental pollution, and there is a tendency for them to be regulated. For this reason, large numbers of pests often occur, causing great damage to agricultural crops.

Under the above circumstances, without spraying pesticides on crops,
BACKGROUND ART Attracting lights or insect-repellent moth lights are attracting attention for capturing or eliminating pests.

Here, the killing light uses the light-tracing properties of pests such as night moths and scarab beetles to kill or capture the pests that fly in search of light. Incidentally, phototropism is a habit in which the reproductive response is stimulated by light with a wavelength of 300 to 470 nm in the dark-adapted state a (a state in which the insect's eyes are accustomed to darkness), and the pest attracts light.

In addition, moth-proof lights use the repellency of pests such as night moths to exclude them from a certain range (farm).The repellency refers to the repellency of light with a wavelength of 500 to 700 nm in a dark-adapted state. Their appetite and reproductive response are reduced by light, and they have a habit of shying away from light.

Next, Figure 5 shows the infestation status of Acaegriba, which is a night moth that exhibits the above-mentioned photogenic and repellent properties.
It shows the transition of the infestation situation at temperature 25°C, and the solid line shows the infestation situation at 25°C. As is clear from the figure, the temperature is 20
℃, they only appear for 4 hours after sunset and are inactive after that. On the other hand, at a temperature of 25°C, they are active all night with a peak around 2 hours after sunset, and their active range is about 25 hours a day. In addition, in order for the eyes of Acaegriba to become accustomed to the surrounding light, a certain amount of pigment must be generated in the eyes, and even if the surrounding light suddenly changes, it takes about 1 to 1 hour to adapt to the sudden change in light. It took five hours, and during that time the light from before the sudden change still remained in my eyes.

[Prior art and its problems]

As shown in the main part configuration diagram of FIG. 4, the conventional killing lamp has a light emitting body 91 for attracting pests and a tray 92 for catching insects provided below the light emitting body 91. A liquid 93 for capturing or killing pests is stored in the tray 92.

Thus, according to the above-mentioned killing lamp, after sunset, the luminous body 91
When lit, pests are attracted to the light of the luminous body 91,
The light flies around the light emitter 91. And the pests are the tray 92
The light reflected on the surface of the liquid 93 is determined, and the receiver falls onto the plate 92.

Pests that fall into this liquid 93 are unable to fly away,
It will lead to death.

However, if the above-mentioned light emitter 91 is turned on at all times (this may attract pests all night, which may seem preferable, but at night when the temperature is below 20 degrees Celsius, pests may be infested). In view of this, the power consumed by the light emitting body 91 is wasted.

[Object of the present invention]

The present invention has been devised in view of the above problems,
The purpose is to provide a lighting method for pest extermination lights that efficiently lights up the luminous body, taking into consideration the habits of pests.

[Specific Means for Achieving the Object] The specific means taken to achieve the object of the present invention is a lighting system for a pest control lamp having a luminous body that emits light of a specific wavelength to attract or expel pests. , after lighting the light emitting body continuously for a predetermined period of time, the light emitting body is caused to blink. Further, the continuous lighting time is set to at least 1.5 hours including 2 hours after sunset, preferably 3.5 to 4.5 hours after sunset, and the light-off time in the blinking operation is less than 1.5 hours. This is what I set.

〔Example〕

Hereinafter, the lighting method of the pest control lamp of the present invention will be explained based on the drawings.

FIG. 1 is an external view of the killing light.

The killing light consists of a pole 2 erected on the ground, a solar cell 3 installed on the pole 2, a light emitter 4 for attracting pests, and a light emitter 4 installed below the light emitter 4. , a controller, and a battery box 7 housing a battery (none of which are shown).

Although not shown, the solar cell 3, the light emitter 4, and the battery box 7 are connected so that the electromotive force of the solar cell 3 is charged to the battery, and the electric power of the battery is supplied to the light emitter 4. It has become.

The solar cell 3 is attached to the top of the support column 2 at a predetermined slope so that sunlight can be effectively received.

The light emitter 4 is comprised of a black light, a blue light lamp, etc. that emits blue and white light that effectively attracts pests, and is attached to the support post 2 by a light emitter bracket 41.

The tray 5 of the insect trap is made of a material with excellent chemical resistance, such as vinyl chloride or polyethylene, and has a box shape with an open top. Further, it is firmly attached to the support column 2 by a support arm 51. In this insect trap, a liquid 52 for trapping pests is stored in a tray 5.

Next, the lighting method of the killing lamp of the present invention will be explained based on the block circuit diagram of FIG. 2 and the time chart of FIG. 3.

The main lighting circuit for the killing light 1 is the solar cell 3, battery BT, and switching S! /4 and the light emitting body 4 are connected to each other. The control circuit also includes a lighting determination circuit 21 that detects the electromotive voltage of the solar cell 3 and detects the amount of surrounding light, and a timer circuit 22 that is driven by the output of the lighting determination circuit 21.
It is composed of a blinking operation control circuit 23 that outputs an output at a predetermined period, and a gate circuit 24 that performs a logical sum of the outputs of the timer circuit 22 and the blinking operation control circuit 23.

The lighting determination circuit 21 has a constant voltage circuit, and when the electromotive voltage of the solar cell 3 becomes below a certain level, the timer circuit 22
and gives a signal a for activating the blinking operation control circuit 23.

The timer circuit 22 is activated for a predetermined time T after the signal a from the lighting determination circuit 21 is input, and outputs a lighting signal S for continuously lighting the light emitter 4 to the gate circuit 24.

When the blinking operation control circuit 23 receives the signal a from the lighting determination circuit 21, it outputs a blinking pulse signal C with a predetermined period S to the gate circuit 24.

The gate circuit 24 calculates the logical sum of the lighting signal from the timer circuit 22 and the blinking pulse signal C from the blinking operation control circuit 23, and provides the output to the switch S- of the main lighting circuit. Specifically, as shown in the time chart diagram of FIG.
is lit continuously, and thereafter, based on the blinking pulse signal C of the blinking operation control circuit 23, a signal is outputted to cause the light emitting body 4 to blink and emit light.

Here, a predetermined time T for continuous lighting of the timer circuit 22
In this case, the electromotive voltage of the solar cell 3 is below a certain level, for example, from 3.5 to 3.5 from sunset (it is difficult to match perfectly).
It is set to 4.5 hours. This was set in consideration of the pest infestation situation shown in Figure 5, and if the light is left on for approximately 3.5 to 4.5 hours, pests will be effectively attracted to the luminous body 4 regardless of the temperature. Can be done.

Further, the blinking period S set in the blinking operation control circuit 23 is set to have a turn-off time of less than 1.5 hours, for example, the duty ratio is 50χ and the blinking period is 1 minute.

This is to prevent the pigment generated in the eyes of the pests from disappearing on the luminescent body 4 during the above-mentioned continuous lighting period. That is, during the light-off period in the blinking operation, pests
It is sensitive to the luminescent material 4 due to the afterglow effect caused by the dye. Then, the next lighting period will arrive before the dye dissolves.

According to the above-mentioned lighting method, there is a pest-tracing effect equivalent to that of a method in which the light-emitting body 4 is turned on all night, and in addition, the amount of electromotive force consumed by the solar cell 3 consumed by the light-emitting body 4 is reduced. Can be done.

Next, I will explain the moth-proof lamp, which is a pest lamp.

The moth-proof lamp uses a yellow light lamp or the like that emits a strong wavelength of 500 to 700 nm as a light emitting body 4. Incidentally, the tray 5 is not required for the insect trap.

When using this moth-proof lamp, the predetermined period T of continuous lighting of the timer circuit 22 is set to a short period of time (at least 1.5 hours) from sunset.

By setting the continuous lighting time T to 1.5 hours or more, a sufficient amount of pigment sensitive to light with a wavelength of 500 to 700 nn+ is generated in the eyes of pests, thereby providing repellency to the pests that have started their activities. .

Further, the blinking period S set by the blinking operation control circuit 23 makes the turn-off time less than 1.5 hours.

For example, the duty ratio is 50χ and the blinking period is 1 minute.

This is to prevent pests from adapting to the dark and becoming more active during the period when the light emitter 4 is turned off.

According to this lighting method, there is a pest-repelling effect equivalent to that of the method of continuously lighting the light emitting body 4 all night, and the amount of electromotive force consumed by the solar cell 3 can be reduced.

According to the lighting circuit described above, a timer circuit and a blinking operation control circuit are used, but a microcomputer or a counter IC may also be used to output a similar lighting operation signal, or a lighting discrimination circuit may simply include a photoelectric element. , CdS, etc. may also be used.

In the above embodiment, a solar cell is used as a power source for the light emitting body,
Although the pest light has a smaller solar battery and is lower in cost, a commercial power source may be used as the power source, and a reduction in power charges can be expected.

〔Effect of the invention〕

As mentioned above, the present invention continuously lights up a light emitter with a predetermined wavelength at a predetermined time when pests are active regardless of temperature changes, and then continuously lights up a light emitter with a predetermined wavelength, taking into account the change time of the pigment in the pest's eyes. Since the luminous body is made to blink, the effect of attracting or eliminating pests can be maintained at the same level as when the light is continuously read all night, and the power consumption of the luminous body can be reduced. This is a method of lighting pest control lights that can save costs.
