Description

  The present invention relates to an insect attracting apparatus.

  The insect attracting device is used in an insect trap (including insecticide) device and the like, and attracts insects by radiating electromagnetic waves preferred by insects (mainly flying insects). As the sight of insects, electromagnetic waves in a wide wavelength range of 240 nm to 560 nm are sensed. Of these, 240 nm to 400 nm is an ultraviolet region, which is a range that cannot be perceived by humans.

  Therefore, insects tend to be directed toward those in which the above-mentioned detectable electromagnetic waves are radiated (including reflection) and the radiating object can be recognized. In particular, it is easy to imagine going further toward the light (electromagnetic wave) where the same kind gathers for mating. Considering this, even electromagnetic waves have more preferred wavelengths. In other words, there is a highly sensitive electromagnetic wave region, and the preferred wavelength varies slightly depending on the type of insect.

  Also, animals are generally easier to recognize when they are moving than when they are stationary. Therefore, it is desirable to move the insect lamp in order to increase the insect attracting effect. However, in order to move, a motor or other operating device is required, which not only increases costs but also causes failure.

  Therefore, it has been considered that the insect attracting device (lamp) flashes recently. This is because blinking is said to improve the insect attracting effect as well as the movement (Patent Document 1).

In addition, many insects prefer (sense) ultraviolet rays of about 370 nm, but as described above, they do not sense only ultraviolet rays but also the visible light range. Therefore, what radiates | emits both visible light and an ultraviolet-ray is also considered like patent document 2. FIG.
However, these prior arts still have a deficient aspect as an insecticidal effect.

  Therefore, the present invention provides a simple device that efficiently attracts insects using a mixed electromagnetic wave of ultraviolet rays and visible light.

  In view of the situation as described above, the present inventor has completed the present insect attracting apparatus as a result of earnest research, and the feature thereof is that at least one LED for ultraviolet rays that emits electromagnetic waves having a wavelength of 230 to 400 nm is used. , Having at least one LED for visible light emitting an electromagnetic wave having a wavelength of 400 nm or more, and blinking both the LED for ultraviolet light and the LED for visible light, and the blinking frequency of the LED for ultraviolet light and the visible light The LED blinking frequency is different.

  In the present invention, the insect attracting device is a device that gathers insects by emitting electromagnetic waves of a wavelength preferred by insects. The purpose of collecting is free. In order to keep insects away from places you don't want to go.

An electromagnetic wave having a wavelength of 230 to 400 nm is an electromagnetic wave generally called ultraviolet light. In particular, around 365 nm is important, and many insects prefer electromagnetic waves in the vicinity.
In the insect attracting apparatus of the present invention, at least one LED that emits an electromagnetic wave having a wavelength of 230 to 400 nm may be used, but in practice, many LEDs are usually used. For example, the number is 20 to 100.
Moreover, you may use multiple types which are not the same thing and irradiate the ultraviolet-ray of a different wavelength. For example, a large number of both 230 nm LEDs and 365 nm LEDs are used.

  The advantage of using different types is that the preferred wavelengths differ depending on the insects, so that more types of insects can be attracted, and those in which various wavelengths are inherently mixed are easier to gather. In the same manner as humans, white mixed with various colors is preferable to monochromatic light.

  An ordinary light source emits electromagnetic waves (light) with a wide range of wavelengths as mixed light, but an LED emits electromagnetic waves with a very narrow range of wavelengths. Thus, the LED determines which wavelength of electromagnetic wave the LED emits. Although the emission wavelength width is not constant, it is said that the portion with a high peak is about 20 nm to 50 nm, and the portion with a low peak is 50 to 150 nm. In the present invention, the term wavelength refers to the center wavelength at this time.

  The LED for visible light is the same, and irradiates an electromagnetic wave having a wavelength of 400 nm or more. As in the above, a plurality of types may be used. For example, blue, green, red, etc. Since the preferred color varies depending on the insect, the insecticidal effect is greater when a plurality of insects are used.

  The point of the present invention is that this LED blinks automatically. However, instead of simply blinking, the ultraviolet LED and the visible light LED do not blink simultaneously, but have different frequencies. This is because insects can detect both visible light and ultraviolet light, and thus are considered to be more stimulated when the lighting timing is different.

  Furthermore, it is preferable that the ultraviolet LED has a lower blinking frequency than the visible light LED. This means that even if the frequency of blinking is visible light, it becomes impossible for humans to recognize that it is blinking when the frequency exceeds a certain level. Even with a fluorescent lamp, if it blinks 50 times per second, it is not known whether it is blinking. Therefore, the blinking frequency (the number of blinking times and the number of lighting times per second) should be small to some extent so that the insect can easily recognize. For example, it is 0.2 to 50 times, more preferably about 0.2 to 20 times per second.

  However, for humans, ultraviolet rays cannot be sensed, and any frequency may be used. However, in the case of visible light, if the blinking frequency is low, the blinking can be recognized, which is very uncomfortable. Therefore, the blinking frequency of visible light is preferably a frequency that is higher than the level that humans cannot perceive.

  The frequency that humans cannot perceive is not clear, but is said to be approximately 30 to 40 times / second. Therefore, a frequency of at least 40 times / second or more (preferably 50 times / second) is preferable so that it cannot be detected by humans. It is said that insects can recognize blinking of visible light even at about 50 times / second.

  In the end, it is preferable that ultraviolet rays that can be detected only by insects flash slowly, and visible light that humans can detect and feel uncomfortable flashing flashes quickly (to the extent that humans cannot detect it).

  Furthermore, in the case of using a plurality of types of ultraviolet LEDs (different wavelengths), the respective blinking frequencies may be changed. For example, 240 nm is 2 times / second, 320 nm is 10 times / second, 365 nm is 20 times / second, and the like. Each of them is lit up at a different timing, so it is considered to be very conspicuous.

  The method of blinking automatically blinks if it is an AC power supply, but an inverter may be used to adjust the number of times. Of course, the flashing method and circuit are free.

In the insect attracting apparatus of the present invention, the arrangement and the number ratio of the LED for ultraviolet light and the LED for visible light are arbitrary. Visible light and ultraviolet rays may be arranged at random or according to a certain rule. Moreover, the ratio of the number of LEDs for ultraviolet light and LEDs for visible light varies depending on the insects. Moreover, since the output of the LED for ultraviolet rays may be weak (and vice versa), the number may be adjusted by taking them into account. For example, the ratio of UV LEDs to visible LEDs is 10: 1 to 1:10.
Moreover, you may provide LED and other lamps which do not blink. The wavelength is also free.

  The insect attracting apparatus of the present invention can be used in place of an insect trap lamp, an ultraviolet lamp or other light emitters in addition to a normal insect trap. Of course, there is no problem even if it is used other than the insect trap.

The insect attracting apparatus of the present invention has the following great advantages.
(1) Since the ultraviolet rays are blinking, insects are easy to detect and are very worrisome. Therefore, the insect attracting effect is great.
(2) There is no unpleasant feeling even if the ultraviolet ray blinks because it is unknown to the person.
(3) Insects that emit visible light also have a greater insecticidal effect.

It is a top view which shows an example of this invention insect attracting apparatus.

Hereinafter, based on an Example, this invention is demonstrated in detail. The following embodiment is an example, and the present invention is not limited to this.
FIG. 1 is a plan view in which three types of LEDs are alternately arranged on the base 2 of the insect attracting apparatus 1 of the present invention. In this example, the LEDs are arranged in a plane on one surface of the substrate 2. In this example, the wavelength of the radiated electromagnetic wave of LED-A3 was 230 nm, the wavelength of the radiated electromagnetic wave of LED-B4 was 365 nm, and the wavelength of LED-C5 was 470 nm.
In this example, there are two columns, but there is no problem with three or more columns.

  The frequency of the LED in this example is 2 times / second for LED-A, 10 times / second for LED-B, and 50 times / second for LED-C. Ultraviolet light blinks slowly, making it easier to recognize insects, and visible light to prevent humans from seeing blinks.

  Although this was tested for the effect of attracting various flying insects, a considerable effect was observed.
