Pest prevention and control solid-state photoelectric device, prevention and control device and application

Abstract

The invention relates to the field of pest control, in particular to a pest prevention and control solid-state photoelectric device, a pest prevention and control device and application. The pest prevention and control solid-state photoelectric device comprises a first light-emitting part and a second light-emitting part. The first light-emitting part emits first emitted light with the peak wavelength ranging from 400 nanometers to 490 nanometers. The second light-emitting part comprises a conversion body, the first emitted light with the light intensity being at least 5% is converted into second converted light through the conversion body, and the wavelength of the second converted light is larger than that of the first emitted light; and the second converted light includes at least one of the following: converted light with the peak wavelength of 500 nm to 570 nm and the full width at half maximum of not more than 40 nm, and converted light with the peak wavelength of 560 nm to 590 nm and the full width at half maximum of not more than 40 nm. The invention further provides the prevention and control device comprising the device. The pest prevention and control solid-state photoelectric device and the prevention and control device are applied for preventing and controlling pests, accurate pest prevent and control is realized through intelligent control, the pests can be effectively killed, and ecological balance cannot be destroyed; and operation is simple, and large-scale popularization is facilitated.

Description

technical field [0001] The invention relates to the field of pest control, in particular to a pest control solid-state photoelectric device, a control device and its use. Background technique [0002] Pest control is of great value in agriculture as well as industry. Insects use the optic organ as an organ to perceive light stimulation, which makes insects show sensitivity to different light spectra. The ommatidia or ocelli of insects contain visual cells that are sensitive to a specific range of spectra. There are transmembrane opsins and chromophores on the cell membranes of visual cells, which constitute photosensitive pigments. The spectral absorption of photosensitive chromatograms largely determines Spectral sensitivity of photoreceptor cells. Pest control can be achieved by utilizing the sensitivity of insects to a specific range of light spectrum. Generally, the main light sources used to control pests can be divided into two categories: one is to use the visual s...

Problems solved by technology

However, it is difficult for a single light source to produce a good trapping effect on various insects at the same time.

When LED devices of different colors are used in combination, because the LED devices of different single-primary colors have different operating voltages and operating currents, the drivers required for LED lights based on different single-primary colors are also different, making the control circuit structure of the lighting system It is complex and puts forward higher technical requirements for intelligent control technology; and the cost of different primary color LED devices is completely different, and the high cost is not suitable for large-scale promotion and use
