Embodiment 1

[0069] Embodiment 1 provides a light control device, which includes a solid-state light-emitting device for pest control. The surface of the element is provided with a second light-emitting element, the second light-emitting element contains a narrow-wave green phosphor material, which is adjusted so that about 10% of the light intensity of the first emitted light is converted into a second conversion by the narrow-wave green phosphor material. Light. The device is connected with the controller to realize the control of the light intensity, light time and luminous frequency of the device. The device is then placed in multiple fields with the same conditions for pest control. Perform pest bioassays at regular intervals.

[0070] Use the blue LED chip to excite the above-mentioned device with narrow-wave green light phosphors for pest trapping and control, and use the treatment group without pest control treatment as the blank control group, and count the collected pests every...

Embodiment 2

[0073] Embodiment 2 provides a light control device, which includes a solid-state light-emitting device for pest control. The surface of the element is provided with a second light-emitting element, and the second light-emitting element contains a narrow-wave yellow light phosphor material, which is adjusted so that about 50% of the light intensity of the first emitted light is converted into the second light through the narrow-wave yellow light phosphor material. Light. The device is connected with the controller to realize the control of the light intensity, light time and luminous frequency of the device. The device is then placed in multiple fields with the same conditions for pest control. Perform pest bioassays at regular intervals.

[0074] The treatment group without pest control treatment was used as the blank control group, and the collected pests were counted every 3 days. The results show that the 580-590nm yellow light band is the best for pest control by using...

Embodiment 3

[0078] Embodiment 3 provides a light control device, which includes a pest control solid-state light-emitting device, the device includes a substrate, the surface of the substrate is provided with a first light-emitting element, the first light-emitting element is an LED purple light chip, which emits purple light, and the first light-emitting element Part of the surface of the element is provided with a second light-emitting element, the second light-emitting element contains a narrow-wave green phosphor material, which is adjusted so that about 15% of the light intensity of the first emitted light is converted into the second light by the narrow-wave green phosphor material. Convert light. The device is connected with the controller to realize the control of the light intensity, light time and luminous frequency of the device. The device is then placed in multiple fields with the same conditions for pest control. Perform pest bioassays at regular intervals.

Abstract

The invention relates to the field of pest prevention and control, in particular to a pest prevention and control solid-state light emitting device, an appliance and a pest prevention and control method. The device comprises a first light emitting element and a second light emitting element. The first light emitting element emits first emission light with the peak wavelength ranging from 300 nm to490 nm. The second light emitting element comprises a light converter, the second light emitting element converts the first emission light with the light intensity being at least 5% into second conversion light through the light converter, and the wavelength of the second conversion light is larger than that of the first emission light. The full width at half maximum of the wavelength of the first emission light and the second conversion light does not exceed 40 nm. The illumination prevention and control appliance comprising the device is further provided. The device or the appliance is usedfor pest prevention and control, accurate pest prevention and control can be achieved, ecological balance cannot be destroyed, cost is saved, operation is simple, and large-scale popularization is convenient.

Description

technical field [0001] The invention relates to the field of pest control, in particular to a solid-state light-emitting device and device for pest control and a pest control method. 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 ...
