Pest control has important value for agriculture and industrial fields. Insects have a visual organ as the organ that senses the light stimulus, so that the insects exhibit sensitivity to different spectra. The compound eye ommatidium or single eye of the insect contains visual cells which are sensitive to a spectrum in a specific range, transmembrane opsin and a chromophore exist on the cell membrane of the visual cells, the transmembrane opsin and the chromophore constitute a photosensitive pigment, and the spectral absorptivity of a photosensitive chromatogram determines the spectral sensitivity of the photosensitive cells to a great extent. By utilizing the sensitivity of insects to a specific range of spectra, pest control can be achieved. The main light sources commonly used for pest control can be divided into two broad categories: one is that the visual sensitivity of the insect is near 365 nm-480 nm; in this spectral range, for example, a black light fluorescent lamp (spectrum peak at 365nm) can be used to achieve good pest trapping effect. The other type utilizes the visual sensitivity of pests to the spectrum of about 500 nm-590 nm, and the insects mainly show the photophobia to a yellow-green light source area; in this spectral range, for example, yellow lamps can be used to achieve pest control.
The use of spectral sensitivity of insects to control pests, while achieving great success, has been associated with a growing number of problems. For example, the main wavelength of the black light lamp is the ultraviolet band, although the black light lamp has strong penetration capability and strong trapping and killing capability, the capability of trapping and killing pests is limited due to the fast attenuation of light intensity; but also can cause the result of broad-spectrum trapping and killing of various harmless beneficial insects, and the long-term use of the insect trap and the killing of pests can destroy the diversity of ecological environment. The mercury lamp uses mercury as basic element and fills other metal or other compound, which uses the radiation ultraviolet of mercury vapor in the discharge process to make the fluorescent powder emit visible light; although the performance of the high-pressure mercury lamp is superior to that of the black light lamp, the high-pressure mercury lamp has the disadvantages of large power consumption, high input voltage, large occupied area, incapability of moving at will, potential safety hazards and high cost, and the development of the high-pressure mercury lamp is limited to a certain extent.
The characteristic of narrow spectrum of the monochromatic LED is utilized for preventing and controlling pests, and the advantage of good light control effect on a certain pest can be shown. But a single light source is difficult to generate a good trapping effect on various insects simultaneously. When the LED devices with different single primary colors are combined and applied, because the working voltages and the working currents of the LED devices with different single primary colors are different, and drivers required by the LED lamps based on different single primary colors are different, the control circuit structure of the illumination system is complex, and higher technical requirements are provided for the intelligent control technology; and the cost of different primary color LED devices is completely different, and the cost is high, so that the LED device is not suitable for large-scale popularization and application.
Further improvements are needed to develop a novel light source for pest control to improve the pest control effect.
Disclosure of Invention
The control of pests faces a number of problems. Although the commonly used lamps such as high-pressure mercury lamps, frequency vibration type insecticidal lamps and solar energy insecticidal lamps can control pests to a certain extent, the lamps also have certain limitations. For example, as phototactic insects, phototactic insects of different species have different light source selectivity, and phototaxis of insects often have different geographical and seasonal specificities, as well as species-to-species differences. Therefore, generally speaking, it is difficult to trap all phototactic pests with the same lamp, and the lamp cannot solve all the pest problems. The phototaxis intensity of insects is often influenced by self insect states and environmental conditions, and if no proper environmental conditions and flying insect states exist, various insect killing lamps are not good for even if field pests are outbreak greatly. And the insecticidal lamp can trap and kill some beneficial insects or harmless insects while preventing and controlling pests, thereby destroying biological diversity.
How to develop a light source device or a pest prevention and control device which can adapt to different pests, so that the probability of killing beneficial insects or harmless insects can be reduced, and the ecological environment can not be damaged; but also can attract pests to achieve the purpose of trapping and killing the pests. How to trap and kill as many pests as possible or as many kinds of pests as possible, so that the specificity of the pest prevention and control device for trapping and killing the pests is improved, the working efficiency is improved, and the pest prevention and control device is convenient to install or use and more convenient to popularize and apply in a large scale; the pest control work can be greatly promoted.
Therefore, the invention provides the pest prevention and control light source device and the pest prevention and control device, which are applied to pest control, have strong trapping and killing specificity on pests, can simultaneously trap and kill various pests, and reduce the probability of killing beneficial insects or harmless insects. And the method is simple to operate, low in cost and suitable for large-scale popularization and application.

In addition, the second emitting light may further optionally include: converted light having a peak wavelength between 610nm and 660nm and a full width at half maximum of no more than 40 nm.
The pest control light source device provided by the invention comprises a first light emitting element and a second light emitting element, wherein the first light emitting element can emit emitted light with a peak wavelength of 310-400 nm (such as 330-400 nm), and the second light emitting element comprises a converter which can convert part (such as at least 5% light intensity, at least 10% light intensity, at least 15% light intensity, at least 20% light intensity, at least 25% light intensity, at least 30% light intensity, at least 35% light intensity, at least 40% light intensity and the like) of the first emitted light into second converted light, so that the wavelength of the second converted light is longer than that of the first emitted light.

By increasing the converted light, the effect of pest control can be further enhanced. Therefore, the pest prevention and control light source device not only can emit short-wave emission light, but also can simultaneously emit narrow-wave conversion light converted from the short-wave emission light, so that one pest prevention and control light source device can emit light waves with one or more wavelength bands, the light source requirements of trapping and killing various pests can be met simultaneously, and the various pests can be trapped and controlled simultaneously; moreover, because the converted light shows narrow waves, the specificity for trapping and killing pests is good, and the negative effect of broad-spectrum disinsection is not caused; in addition, the second converted light is directly converted from the first emitted light, and light waves of different wave bands are not required to be obtained by combining multiple light sources (for example, purple light waves and yellow light waves are emitted through a purple light semiconductor chip and a yellow light chip respectively), so that the design problem of a complex driving circuit structure is avoided, the cost is greatly reduced, the operation is simple, and the large-scale popularization is suitable.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one such feature. In the description of the present invention, "plurality" means at least two, e.g., two, three lamps, unless specifically limited otherwise.
Herein, the term "light intensity" is used to indicate the intensity of light and the amount of the surface area of an object that is illuminated. This can be expressed in a calculation manner commonly used in the art, for example, the luminous flux (lux) of the received light per unit area can be calculated. And may be calculated in other ways.
Herein, the reference to "light source device" refers to a device that converts an electrical signal into an optical signal. "prevention and control of pests" may refer to prevention of pests, control and management of pests, and the like. As used herein, reference to "pests" is to be interpreted broadly, in the sense that pests are generally understood, and in the sense that pests are not needed or are harmful to a particular environment.
Herein, reference to pest control light source devices may be made in any solid state form or any shape commonly used in the art. For example, the corn can be made into various shapes such as a cage shape, a corn shape, a cylindrical shape, a conical shape, a trapezoid shape and the like.
Herein, reference to a peak wavelength is to be understood in the general sense of the art to refer to the wavelength at which the spectral luminous intensity or radiant power is at a maximum. Wherein the first light-emitting element emits first emission light having an emission light with a peak wavelength between 310 nm and 400nm (the emission light is violet light as it is commonly known in the art). Light with a peak wavelength between 500nm and 570nm, which is also commonly referred to in the art as green light; light having a peak wavelength between 560 nanometers and 590 nanometers, which is also commonly referred to in the art as yellow light; light having a peak wavelength between 610nm and 660nm is also commonly referred to in the art as red light. Light having a peak wavelength between 400nm and 490 nm is also commonly referred to in the art as blue light. That is, the converted light obtained by the converter may be any one of blue light, green light, yellow light or red light, and the light waves can effectively trap or control pests, thereby improving the pest control effect. Of course, the peak wavelengths listed above are typical wavelengths of blue, green, yellow or red light and violet light, and in practical applications, the above strict limitation is not required to be observed for the peak wavelengths of these lights.

The reagents or instruments used are not indicated by the manufacturer, and are all conventional products commercially available.
Example 1

In addition, the purple light semiconductor chip and the LED green light chip are combined and applied as a comparison experiment to be used for pest control. Experiments show that when the LED purple light semiconductor chip and the LED green light chip are combined and applied, a large number of complex control circuits are needed for adjustment. And although the pest results are not obviously different from the device containing the purple light semiconductor chip and the narrow-wave green light phosphor provided by the invention, the cost is greatly increased. This is mainly because, on the one hand, the cost of the LED chip is higher than that of using a narrow-wavelength green phosphor material to obtain a corresponding narrow-wavelength; on the other hand, the green LED chip itself has high cost and low luminous efficiency because the green LED chip has a high In composition In the active region, which results In a higher defect density and a larger polarization electric field.
Example 2

The result shows that the device containing the purple light semiconductor chip and the narrow-band yellow light phosphor provided by the invention is used for pest control, and the yellow light band of 580-590nm is the best. The intermittent illumination frequency, the dark time can not exceed 0.5 second, the illumination time must exceed 1.5 second, can effectively keep the photopic adaptation state of the cotton bollworm, thereby exerting the control potential in the control of cotton bollworm population and effectively controlling more than 95 percent of pests.
The pest prevention and control device utilizes the purple light LED chip to excite the narrow-wave yellow phosphor, and researches the influence of the pest prevention and control device on the copulation and oviposition of the cotton bollworm adult. The result shows that in the initial oviposition stage, the violet LED chip and the 589nm yellow light are adopted for continuous irradiation, and the ineffective egg rate of the cotton bollworms is higher than that of the normal dark treatment group; in the middle stage of spawning, the ultraviolet LED chip and 589nm continuous irradiation are adopted, and the ratio of ineffective eggs is obviously higher than that of normal dark treatment. The irradiation of purple light and yellow light can obviously block the mating of cotton bollworms, so that the spawning rate (hatching rate) is reduced by more than 60 percent.
In addition, the purple light semiconductor chip and the LED yellow light chip are combined and applied as a comparison experiment to be used for pest control. Experiments show that when the purple light semiconductor chip and the LED yellow light chip are combined and applied, a large number of complex control circuits are needed for adjustment. Although the result is not significantly different from the device provided by the invention, which contains the purple light semiconductor chip and the narrow-band yellow light fluorescent body, the cost is greatly increased.
