Description

The present invention relates to a method for producing an insect repellent light source for controlling insects such as night moths and stink bugs, which are pests of agricultural products such as vegetables and fruit trees.

  The night mosquitoes that carry out nighttime harming activities include Akebonohaha and Akaeguriba which absorb the mature fruits of fruit trees, and vegetables such as tomatoes, leeks, ginger, carnations, chrysanthemum, etc. There is Awanomeiga.

As a method for preventing damage to crops of these night owls, there is a method utilizing the light running property, and representative fluorescent light sources include a blue fluorescent lamp and a yellow fluorescent lamp (for example, see Patent Document 1) . A blue fluorescent lamp emits light in a wavelength range of 0.30 μm to 0.55 μm, and its maximum emission peak is in the vicinity of 0.43 μm, and generally induces an attracting action.

  The yellow fluorescent lamp emits light in the wavelength range of 0.50 μm to 0.70 μm, the maximum emission peak is near 0.585 μm, and this phosphor has a main emission peak wavelength near 0.585 μm, Light in a short wavelength region of 0.50 μm or less is blocked with a pigment containing titanium yellow. The mechanism of insect control of yellow light is to avoid night moss or suppress behavior by making the compound eyes clear, and it is said that the illuminance required for this is about 1 lux or more.

When using a blue fluorescent lamp, it is necessary to catch flying insects. However, since it is very difficult, yellow fluorescent lamps are more effective as a light source for insect protection.

  The radiation wavelength range where insect repellent or attracting action varies depending on the type. For example, in the same night moth, Shirochimojito is repelled by radiated light having a wavelength range of 0.43 μm, and Tobacco moth is 0.53 μnm or longer, and attracts at a shorter wavelength range.

  However, it is said that any insect that exhibits phototaxis exhibits behavioral inhibition or repelling behavior in the emitted light in the long wavelength range of about 0.50 μm or more, and a conventional yellow fluorescent lamp is produced based on this behavior.

  Conventional yellow fluorescent lamps have a low amount of radiated light, and the number of installed lamps must be increased in order to maintain the minimum illuminance for insect control.

  An object of the present invention is to provide an insect repellent light source that eliminates the above-described problems and has a higher amount of radiated light.

In order to achieve the above-mentioned object, the method of the present invention is effective for the long-wavelength side emission of about 0.50 μm or more and for the coating and clearing using imidazolone pigment for blocking the short-wavelength side of less than 0.50 μm. An appropriate proportion of the mixture is applied to the arc tube or its outer bulb as follows .
(1) A method for producing an insect repellent light source by mixing an imidazolone pigment, a clear, a curing agent, and a thinner and applying the mixture to a glass tube of a white fluorescent lamp, wherein the insect repellent light source comprises an imidazolone pigment and a clear By applying the mixture, the short wavelength side of the radiated light below 0.50 μm is blocked, and the short wavelength side is changed in the range from 0.45 μm to 0.53 μm by changing the clear ratio. A method for producing an insect repellent light source characterized by
(2) Imidazolone pigment and clear are mixed at a ratio of 6: 5, mixed with a curing agent and thinner, and applied to a glass tube of a white fluorescent lamp having a color temperature of 4,200 K. To create a light source .

  According to the present invention, a more effective light source than conventional yellow fluorescent lamps can be produced, and furthermore, by changing the content of the imidazolone pigment, it is possible to easily produce an insect-proof light source that can cope with various insects with the same arc tube.

  Hereinafter, preferred embodiments of the present invention will be described. The light source for insect repellent is to block the wavelength region below 0.50 μm and transmit the wavelength region above it efficiently.

  Benzimidazolone, clear, curing agent and thinner are mixed at a ratio of 6: 5: 5: 13 and applied to a glass tube of a white fluorescent lamp (color temperature 4,200 K). Here, by changing the clear ratio, the short wavelength side of the emitted light can be easily changed from 0.45 μm to 0.53 μm.

  The spectral distribution characteristics of the insect-proof fluorescent lamp according to the present invention are shown in FIG. This fluorescent lamp has a maximum emission peak in the vicinity of 0.545 μm, and has an illuminance about 1.3 times that of a conventional yellow fluorescent lamp.

It is a spectral characteristic figure of the light source for insect prevention.
