Gas discharge device and method for insecticidal technology

The present invention relates to the field of lighting technology, and more particularly to a high-intensity gas discharge device and method that can be used for insecticides. Background technique

China's prevention and control of crop diseases and insect pests mainly rely on chemical control measures such as pesticides. Farmers have to use pesticides and insecticides to avoid pests and increase production. In addition to controlling the damage of pests and diseases, it also brings rise in pest resistance. , increased incidence of pests and diseases, serious environmental pollution such as water and soil resources, food safety and other issues. By promoting the application of green prevention and control technologies for physical control, it not only helps to protect biodiversity, reduces the incidence of pests and diseases, achieves sustainable control of pests and diseases, effectively replaces the use of highly toxic and highly residual pesticides, and reduces the production process. Risks of pest and disease prevention and control operations, avoiding human and animal poisoning accidents, and significantly reducing non-point source pollution caused by pesticides and their wastes, and helping to protect the agricultural ecological environment.

Throughout the drawings, the same or similar reference numerals indicate the same or similar devices (module) or steps. detailed description

In the detailed description of the preferred embodiments that follow, reference is made to the accompanying drawings that form a part of the invention. The accompanying drawings illustrate, by way of example, specific embodiments The exemplary embodiments are not intended to be exhaustive of all embodiments in accordance with the invention. It is to be understood that other embodiments may be utilized and structural or logical modifications may be made without departing from the scope of the invention. Therefore, the following detailed description is not to be construed as limiting the scope of the invention. Insects do not respond to the light source emitted by the lamp or disturb its light sensing capability, even if the light source cannot be a cause of insect response. For example, by preventing light transmission in a certain wavelength range or controlling light in a wavelength range of reading, insects can be prevented from physiologically reacting positively to light, and insect activity will be weakened. In this way, insects' nighttime foraging, courtship, orientation, avoidance of enemies, dormancy, diapause and other activities will be greatly affected, thereby eliminating pests.

1 is a lighting device in accordance with an embodiment of the present invention. The lighting device 10 includes a power supply unit 101, a photosensitive switch unit 102, a lighting control unit 103, and a lighting unit 104.

The power supply unit 101 is configured to connect an external power source and supply power to other parts. The photosensitive switch unit 102 is configured to control the startup or shutdown of the lighting device 10 according to the brightness outside the lighting device 10, that is, control the power supply unit 101 and the external power source and / or the power supply unit 101 and other units between the circuit; the lighting control unit 103 is used to output lighting control commands to the lighting unit 104, thereby controlling the operating mode of the lighting unit 104; the lighting unit 104 is coupled to the lighting control unit 103, according to The received lighting control command to Illuminate by means of flashing and/or continuous illumination.

In this embodiment, the power supply unit 101 transforms the input 1 10V to 220V into 12V, one way as the starting voltage of the lighting unit 104. For example, when the lighting unit 104 is a gas discharge bulb, the power supply unit 101 will activate the gas discharge bulb through the high voltage ballast, and the high voltage ballast will raise the 12V power source to a high voltage pulse voltage of 23,000 volts or more in an instant to activate the gas discharge bulb. The gas in the arc produces a strong glow of higher color temperatures in the arc.

Different insects have varying degrees of sensitivity or response to light of different wavelength ranges, and illumination unit 104 (e.g., a gas discharge bulb) in the present invention needs to emit light that covers the insect sensitive wavelength range.

Preferably, the illumination unit 104 in this embodiment generates a wavelength of 250 nm to

780nm light. That is to say, light with wavelengths of 360 nm, 500 chaos, and 600 nm can affect some types of insects.

When the lighting unit 104 is a gas discharge bulb, the illumination light of the corresponding wavelength can be generated by the internal filling (pill) and the high pressure control or the outer tube of the bulb.

Because nocturnal insects stop moving during the day when the radiant heat of the sun is high in order to maintain a certain body temperature, at night, insects can sense the light within a radius of about 1.5 m to gather. In order to prevent the nocturnal insects from properly sensing the light within the range of their motion and thereby weakening their activity, the illumination control unit 103 will control the illumination unit 104 to operate in a blinking and/or continuous illumination manner, thereby interfering with the insects. activity.

Preferably, the lighting control unit 103 sends a lighting control command to the lighting unit 104 to control the mode of operation of the lighting unit 104. For example, the lighting unit 104 operates intermittently in a blinking and continuous illumination manner based on the control command, thereby inducing chaotic insects to induce light while degrading or blinding the cornea of the insect, greatly improving the pest control effect. Preferably, the interval between the two modes of blinking and 'continuous illumination is 1 to 60 minutes. In this embodiment, after the blinking ends, the illumination unit 104 enters a sleep state, and the sleep duration (or interval time) is 5 to 60. Minutes, then start the way of continuous lighting.

In the above case, when the lighting unit 104 operates in a blinking manner, it will blink at intervals (e.g., 1 second, 5 seconds, etc.). In this embodiment, the photo The blinking frequency of the bright unit 104 is 0.1 to 20 Hz, and the duration of the blinking is 5 to 60 minutes. Preferably, the scintillation frequency is 1 to 5 Hz, and the duration of the flicker is 5 to 10 minutes.

Through the above-described scintillation process, insect-induced light that is in the illumination range can be induced to interfere with its normal activity.

When the illumination unit 104 operates in a continuous illumination mode, the insects will be in the strong light of the wavelength range of their reaction for a long time, and therefore, the cornea of the insect will be degraded, even blind, and normal activities cannot be performed. The lighting unit 104 will continue to illuminate for 1 to 60 minutes. Preferably, the duration of continuous illumination is 5 to 30 minutes.

It will be understood by those skilled in the art that when the lighting unit 104 operates intermittently in a blinking and continuous illumination manner, the two modes of operation are not strictly equivalent. When the type of insect, the application environment or other factors affecting the pest control are changed, the length of time of the two working modes can be adjusted accordingly.

In practical applications, in order to increase the utilization rate of the device and attract more insects, the illumination unit 104 in this embodiment generates illumination light having a color temperature of 4000K to 10000K.

Preferably, the embodiment further includes a power generating unit for generating electric power using solar energy and/or wind energy, thereby eliminating the need for power supply wiring in the farmland, and greatly reducing the cost. Correspondingly, the embodiment may further include a battery coupled to the power generating unit and the lighting device 10 for storing power and supplying power to the lighting device 10. Since the power generating unit and the storage battery are present, the lighting device 10 in this embodiment can be used independently, which is advantageous for large-scale use in agriculture.

Preferably, the embodiment further includes a lamp cover that covers at least a portion of the illumination unit 104 such that the illumination light can be illuminated in a specified direction.

2 is a flow chart of pesticidal according to an embodiment of the present invention. The operation of the lighting device will be explained by taking the lighting device to work intermittently in a blinking and continuous illumination manner.

First, step S11 is performed to detect the surrounding brightness.

In this step, the photosensitive switch unit will determine whether to activate the illumination device based on the brightness around the illumination device.

Step S12, determining whether the surrounding brightness is less than the first threshold? In the i-hai step, the photosensitive switch unit will judge the brightness of the surroundings. If the surrounding brightness is less than the first threshold, step S13 is performed; otherwise, the surrounding brightness is continuously detected.

Step S13, the photosensitive switch unit activates the illumination device.

In this step, the lighting device will obtain power through the decision junction of the photosensitive switch unit to operate.

Step S14, the lighting device performs a blinking process, that is, the lighting unit operates in a blinking manner.

In this step, the illumination unit has a blinking frequency of 0.1 Hz to 20 Hz and a duration of 5 to 60 minutes, thereby inducing the induced light of the chaotic insect.

When the blinking process in step S14 is completed, the process proceeds to step S15, and the lighting device performs a continuous lighting process.

In this step, the lighting unit will continue to illuminate for 1 to 60 minutes, thereby degrading the cornea of the insect.

It can be understood by those skilled in the art that the flowchart in FIG. 2 is only for explaining an example of the embodiment, and the sequence of steps S14 and S15 is not strictly defined. That is, the lighting device may also perform step S15, and then Step S14 is performed.

In addition, it should also be noted that when the lighting device is in operation, the photosensitive switch unit will always detect the change of the surrounding brightness. When the surrounding brightness is greater than the first threshold (for example, when it is bright), the photosensitive switch unit will cut off the lighting control unit, A power connection between both the lighting unit and the power supply unit.

The present invention produces a light line capable of interfering with insect activity by using a gas discharge device, the wavelength of which includes a band in which the insect reacts or is contained in a band in which the insect reacts. Inducing chaotic insect-sensing light is achieved by means of flashing illumination; corneal degradation of the induced insects is achieved by continuous illumination. When the two methods are used at intervals, the insecticidal effect will be greatly enhanced.

Compared with the prior art, this embodiment does not require electric shock or other chemical killing during the insecticidal process, and the tested insecticidal rate can reach more than 90%.

In practical application, the invention can interfere or kill the young worms of the cockroach with various lepidopteran adults, so that the inability to move and normal mating is difficult to breed. Young insects can't feed and starve to death. It has special effects on various adult species of Lepidoptera, such as the diamondback moth, the cotton bollworm, the ground tiger, the heartworm, the mites, the fruit leaf moth, the American white moth and so on. Other major pests include: coleoptera, beetles, steppes, beetles, weevils, etc.; Diptera mosquitoes, flies, crickets, crickets, etc.; Homoptera, locusts, leafhoppers, etc. ; Orthoptera, etc. The invention can significantly inhibit the activity of the above phototaxis pests, has a remarkable insecticidal effect, and inhibits a large number of generations of pests, so that crops such as rice, wheat, corn, sorghum, cotton, sugar cane, tea and fruit trees are no longer dependent on pesticides. Chemical control measures such as pesticides.
