Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention collects and captures harmful insects such as mosquitoes, flies, and moths by using light-emitting diodes (hereinafter abbreviated as "LEDs") as light sources and utilizing the phototaxis of insects. It is about insect traps.

In the present specification, the LED chip itself is called a "light emitting element", and the entire light emitting device including an optical device such as a package resin or a lens system on which the LED chip is mounted is referred to as a "light emitting diode" or "LED". ".

[0003]

2. Description of the Related Art Insect traps for collecting and capturing harmful insects such as mosquitoes, flies, and moths are installed at eaves of stores. This trap is
Utilizing the fact that insects such as mosquitoes, flies, and moths have the characteristic of "phototaxis" that advances toward light, a light source is installed and a trap is provided near the light source to trap harmful insects.
As the trap, there are used a high voltage electric insecticidal device, sticky insect trapping paper, or a container in which water is mixed and a few drops of detergent are mixed. On the other hand, a black light or a fluorescent lamp covered with a blue transparent film is used as a light source for attracting harmful insects. The reason for this is that, as shown in the insect phototaxis curve in FIG. 5, the insect phototaxis is about 300 nm to about 5 with the peak of light having a wavelength of about 360 nm.
This is because it is high in the blue region from the ultraviolet ray of 00 nm. In particular, in the ultraviolet region of about 340 nm to about 400 nm, the phototaxis is remarkably high. For this reason,
A black light that emits ultraviolet rays is often used as the attracting light source.

[0004]

However, in the insect trap using such a black light or a fluorescent lamp, the insect trap also becomes large because the attracting light source is large.
Further, the power consumption of the light source is large and the life is short, resulting in high cost. Further, since a household power source is required as a power source for the light source, it cannot be used outdoors and cannot be carried freely.

In view of the above, the present invention uses a light emitting diode as an attracting light source, is small in size, consumes less power, has a long life and can be manufactured at low cost, and can be used outdoors and can be carried freely. The challenge is to provide vessels.

[0006]

The insect trap according to the invention of claim 1 is an insect trap having an attracting light source and a trapping means, wherein the emission wavelength peak is in the range of about 330 nm to about 420 nm and / or Or about 450 nm to about 520 nm
The LED within the range is used as the attracting light source.

As described above, unless it emits light in the wavelength range having a certain degree of phototaxis in the insect phototaxis curve of FIG. 5, the effect as an attracting light source cannot be exhibited. Therefore, the emission wavelength peak is about 330 nm to about 420.
LEDs in the range of nm or about 450 nm to about 520 n
A sufficient insect trapping effect can be expected by using the LED within the range of m or both of them as the attracting light source. In addition, since the attracting light source is an LED, the attracting light source is small, so that the entire insect trap can be miniaturized.
Since the ED is low in price, has low power consumption, and has a long life, the cost can be reduced. Further, by using an LED as a light source capable of emitting light even in a dry battery or a storage battery, it can be used outdoors and can be used for camping and the like. Further, since it is small and can be used as a power source, even indoors, it can be carried to any place.

In this way, the insect trap is small in size, consumes less power, has a long life, can be manufactured at low cost, can be used outdoors, and can be carried freely.

In the insect trap according to the invention of claim 2, in the structure of claim 1, the LED has an emission wavelength range of about 360 nm to about 400 nm.

As a result, an LED having an emission wavelength range with a markedly high photoemissivity can be used as an attracting light source, and an insect trap with a higher insect trapping effect can be obtained. Moreover, the center emission wavelength of the ultraviolet LED is about 380 nm, and the light emitted by the ultraviolet LED is near ultraviolet light having a long wavelength.
There is almost no harm to the eyes or skin.

In this way, the insect trapping effect is further enhanced, and even if the ultraviolet light emitting element is turned on for a long time, the insect trap does not affect health.

The insect trap according to a third aspect of the present invention is the insect trap according to the first or second aspect, wherein a portion of the trapping means illuminated by the LED is purple or blue at an emission wavelength of the LED. A cover having a large through hole in which a fluorescent material that emits fluorescence is mixed or applied is provided.

As described above, not only is the LED that emits light in the range of high photoactivity as the attracting light source, but a fluorescent material that emits purple or blue fluorescence when illuminated by the LED is placed in a transparent resin or the like. A mixed material or a material such as resin coated on the surface is provided as a cover having a large through hole on the entire surface. As a result, the insect pest is guided toward the attracting light source along the cover that emits purple or blue fluorescence, and falls from a large through hole provided on the entire surface of the cover in the meantime to be captured by the capture means. It becomes a higher insect trap.

An insect trap according to a fourth aspect of the present invention is the insect trap according to any one of the first to third aspects, wherein the L
The ED uses a dry battery or a storage battery as a power source.

Since the black light and the fluorescent lamp have to be plugged into an outlet to take power, the range of movement is limited. However, since the LED emits light with low power, a dry battery or a storage battery can be used as a power source. Therefore, since it can be carried indoors to any place, and can be used outdoors, it can also be used when camping.

In this way, the insect trap can be freely carried anywhere.
