Pest prevention and control light source device, pest prevention and control device and application

Abstract

The invention relates to the field of pest control, in particular to a pest prevention and control light source device, a pest prevention and control device and application. The pest prevention and control light source device comprises a first light-emitting element and a second light-emitting element, wherein the first light-emitting element emits first emitted light with the peak wavelength ranging from 310 nanometers to 400 nanometers; the second light-emitting element converts the first emitted light with the light intensity of at least 5% into second converted light through a converter, and the wavelength of the second converted light is larger than that of the first emitted light; and the full width at half maximum of the second converted light is not more than 40 nanometers, and thesecond converted light comprises at least one of the following: the peak wavelength between 500 nanometers and 570 nanometers, the peak wavelength between 560 nanometers and 590 nanometers, and the peak wavelength between 400 nanometers and 490 nanometers. The invention further provides the pest prevention and control device comprising the pest prevention and control light source device. The pestprevention and control light source device and the prevention and control device are applied to pest control, accurate pest control is achieved through intelligent control, pests can be effectively trapped and killed, and ecological balance cannot be damaged; 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 light source device, a pest control device and its application. 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 combining LED devices with different single-primary colors, because the LED devices with 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 of the lighting system The circuit structure is complex, which 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
