Description

  The present invention relates to an insect lamp.

  Insect lamps are used in insect traps (including insecticides) and the like, and radiate electromagnetic waves preferred by insects (mainly flying insects) to attract 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.

  Of course, as with humans, we avoid the insects moving toward the darkest part. For this reason, the above-described detectable electromagnetic wave is emitted (including reflection) and is directed toward the one that can recognize the radiating object. 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.

  Therefore, in order to catch a pest, it naturally radiates electromagnetic waves with a wavelength preferred by the insect and collects it. In general, many insects prefer (sense) ultraviolet rays of about 370 nm.

  However, as described above, insects do not only detect ultraviolet rays, but also the range of visible light. The same is true for humans, but a mixture of wavelengths of a wide range of visible light is preferable to light of a specific color.

  This is conventionally known, and when compared to the case of using only ultraviolet rays and the case of using both ultraviolet lamps and visible light lamps, the insecticidal effect is greater when both are used.

  However, there is no device that emits both ultraviolet light and visible light in this way, and the device is simply increased in size.

  Therefore, the present invention provides a simple device that can emit a mixed electromagnetic wave of ultraviolet light and visible light.

  In view of the situation as described above, the present inventor has completed the insect-lighting lamp of the present invention as a result of earnest research, and the feature thereof is that the ultraviolet radiation LED and the visible light radiation LED are alternately arranged in a straight line. It is placed and a diffusion cover is provided on the radial direction side, and the distance between adjacent light emitting parts is smaller than the distance between the light emitting part and the diffusion cover. In another aspect, two or more rows of LEDs are provided. Two-dimensionally or three-dimensionally arranged, ultraviolet light emitting LEDs and visible light emitting LEDs are alternately placed in a checkered pattern, and provided with a diffusion cover on the radiation direction side, adjacent light emission The distance between the portions is smaller than the distance between the light emitting portion and the diffusion cover.

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

Ultraviolet radiation LED is LED which radiates | emits an ultraviolet-ray, and the shape of a chip | tip (packaged thing, what was modularized, the combination of several chips, etc.) does not ask | require. Of course, a commercially available product that emits ultraviolet rays may be used.
The ultraviolet rays referred to here may have a wavelength that can be detected by insects, as long as they can emit 240 nm to 400 nm. Even if the entire range of this wavelength cannot be emitted, it is sufficient that ultraviolet rays having a wavelength falling within this range can be emitted. In particular, ultraviolet rays around 365 nm and 375 nm are important, and those capable of emitting these are preferable.

The visible light emitting LED is an LED that emits visible light, and the shape of the chip (packaged, modularized, or a combination of multiple chips) is not limited. Of course, a commercially available product that emits visible light may be used. Among visible light, LEDs that emit electromagnetic waves on the short wavelength side such as blue and green are preferable.
The light emitting unit refers to a diode itself that emits electromagnetic waves.

First, the invention described in claim 1 will be described. In the present invention, the LEDs are arranged in a line. This is a type in which a large number of LEDs are placed in an elongated tube such as a straight tube fluorescent lamp currently on the market. Of course, the present invention is not limited to that type.
In this one-row type, the number of LEDs is arbitrary, but about 4 to 120 is preferable.

  When arrange | positioning in this 1 row | line | column, ultraviolet radiation LED and visible light radiation LED are mounted alternately. A diffusion cover (cover member) that transmits electromagnetic waves is provided at least on the LED radiation side.

  It is one of the points of the present invention to alternately place ultraviolet radiation LEDs and visible light radiation LEDs. Conventionally, there is no one in which two kinds of LEDs are alternately mounted as described above, and only the same LEDs are arranged. In particular, there was no use for aligning ultraviolet light and visible light, and none existed.

  In the present invention, as described above, it has been found that a mixed light of ultraviolet rays and visible light has a higher insecticidal effect. Inventor's experiment was conducted by recalling that mixing was carried out since the effect of attracting insects was small even when ultraviolet rays and visible light were separately emitted in a spot manner.

  Further, a cover member that transmits electromagnetic waves is provided on the surface side of the LED. In the first place, LEDs not only have a narrow wavelength range of radiated electromagnetic waves, but also have a small radiation angle (solid angle, steradian) and do not spread as much as ordinary lighting fixtures. Therefore, a diffusing tool (a diffusing plate or a diffusing film) is provided in front of the LED so as to widely spread and invite insects widely. In this case, although electromagnetic waves are transmitted, they are not transmitted as they are, but are diffused and transmitted in various directions.

  Examples of the diffusion cover include a transparent glass plate and a transparent plastic plate that contain a diffusion material or are coated. In other words, the electromagnetic wave is reflected by the diffusing material contained therein (plastic piece, silica beads, etc. different from the member) and diffused by changing the angle. In addition, a diffusion film may be attached to the transparent member.

  There is also a method of scratching and diffusing the surface of a plastic member with a file or the like. A ground glass is also possible. That is, the method of diffusing is free.

  The diffusion cover may be planar, cylindrical such as a straight tube fluorescent lamp, spherical, or other curved surface.

  Next, the greatest feature of the present invention is that the distance from the radiation surface of the LED to the diffusion cover is equal to or greater than the closest distance between the radiation surfaces of adjacent LEDs. As a result of examining various LEDs, electromagnetic waves from adjacent LEDs are almost mixed by the diffusion cover at this distance. Of course, since it is radiated in a circular shape, it does not completely overlap with the electromagnetic waves from the adjacent side, but most of them overlap.

The distance to the diffusion cover is not less than the closest distance between the emission surfaces of adjacent LEDs, but is up to approximately twice. If the distance is too short, the device will only become large and the effect will not change much.
Further, when the diffusion cover is curved, the nearest portion is set as the distance.

  Next, the invention of claim 2, that is, two or more rows of LEDs are arranged in a plane, and ultraviolet radiation LEDs and visible light radiation LEDs are alternately placed in a checkered pattern. Alternating placement in a checkered pattern means that all adjacent LEDs are different.

In the present invention, the LEDs are not arranged in a single row as in the first aspect of the invention, but in two or more planes.
The arrangement of multiple rows in this way results in fewer UV-only parts and visible light-only parts.

  Even in the case of this plurality of rows, it is the same and the distance between the closest LEDs and the distance to the diffusion cover.

Further, the LEDs may be arranged not only in a planar shape but also in a three-dimensional manner so that electromagnetic waves can be emitted around the entire circumference.
For example, ultraviolet radiation LEDs and visible light radiation LEDs are alternately and linearly mounted on each of a long tube or a rod-shaped flat surface (at least a plurality of surfaces) having a rectangular cross section, and the entire circumference and the whole Is a combination that looks like a checkered pattern. Even in this case, there is a diffusion cover on the outer side, and the distance to the cover is larger than the interval between adjacent light emitting units.

  Further, the LED may be mounted on a specific surface of a cylindrical body or rod body having a cross section that is not a rectangle but an ellipse, a circle, a flat circle, or other curved sections. What is necessary is just to decide by the usage place and usage method of the insect lamp of this invention.

  In this example, the electromagnetic wave in which ultraviolet rays and visible light are mixed spreads over a wider range, and the insect attracting effect is increased.

The present insect attracting lamp has the following great advantages.
(1) Since an electromagnetic wave in which ultraviolet rays and visible light are mixed is radiated in many parts, the insect attracting effect is great.
(2) Special equipment for mixing is unnecessary and inexpensive.

It is sectional drawing which shows 1 part of one example of the insect lamp of this invention. It is a top view which shows the radiation range of the electromagnetic wave of the example of FIG. It is sectional drawing which shows 1 part of one example of the insect lamp of this invention.

Hereinafter, based on an Example, this invention is demonstrated in detail.
FIG. 1 is a cross-sectional view showing a part of an example of a worm lamp 1 according to the present invention. This figure is a side view from the radial direction. A diffusion cover 4 is provided above the LED 2. This LED 2 is composed of alternately arranged ultraviolet radiation LEDs and visible light radiation LEDs. The distance L between adjacent LEDs and the distance H between the LEDs and the diffusion cover 4 are configured such that H is slightly longer. In this example, L is 15 mm and H is 20 mm.

  A broken line 5 indicates a line indicating the spread of radiation. The LED generally has a vertical cross section of about 90 degrees in the radiation area of the electromagnetic wave from the LED placed on a plane. Therefore, as shown in the figure, it overlaps with adjacent radiation waves. Of course, there are also those of 90 degrees or more, but there is no problem because such things overlap more.

  FIG. 2 is a plan view showing a range when the electromagnetic wave in the example of FIG. 1 passes through the diffusion cover. In this figure, the part where two circles overlap is the part where ultraviolet rays and visible light overlap, that is, the part where they are mixed. The other parts are only ultraviolet light or visible light, but this also overlaps outside the diffusion cover, so there is no problem. However, in practice, it is desirable to mix at the time of the diffusion cover material.

  FIG. 3 is a view similar to FIG. 1 but viewed from a direction perpendicular to the direction in which the LEDs are arranged. In this example, it is a type like a straight tube fluorescent lamp. In this figure, L is not known, but H is visible. If the distance of H is various, the shortest H is compared with L.

  FIG. 4 is an example in which the LEDs 2 are arranged in three rows. This is a plan view. The ultraviolet radiation LED 6 and the visible light radiation LED 7 are alternately placed in a checkered pattern. The distances from one LED to the adjacent LEDs in the front / rear and left / right directions are substantially equal. Also in this example, the side view is the same as FIG.

  FIG. 5 is a view similar to FIG. 2, but since it is arranged in three rows, there are many overlapping portions and it is natural that the mixing efficiency is good.
