Description

Technical Field

[0001] The utility model relates to the technical field of insect attracting lamps, in particular to an LED insect attracting lamp tube which emits broadband ultraviolet light. Background Art

[0002] Most pests are easily stimulated by light and move towards the direction close to the light source. This behavior is called positive phototaxis. In agriculture, this phototaxis of pests is often used to attract and eliminate pests using insect traps. Traditional LED insect traps are mostly monochromatic light sources with a narrow spectrum. They can only attract pests sensitive to this wavelength, but not to pests sensitive to other wavelengths, and have low insect trap efficiency. In addition, traditional LED insect traps use light-emitting chips as light sources, so the light emitted is mostly point light sources, which are emitted in all directions and have low luminous efficiency. Utility Model Content

[0003] The utility model aims to provide an LED insect-attracting lamp tube that emits broadband ultraviolet light, which can emit broadband ultraviolet light that attracts a variety of pests, has a wavelength range of 340-400nm, has high insect-attracting efficiency, and the emitted light is concentrated, with high luminous efficiency.

[0004] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0005] An LED insect attractant lamp tube emitting broadband ultraviolet light comprises a lamp board, LED lamp beads, a convex lens and a light conversion glass tube; the characteristics are: the convex lens is sleeved inside the light conversion glass tube, the lamp board is sleeved inside the convex lens, and the LED lamp beads are evenly distributed on the top of the three surfaces of the lamp board.

[0006] Preferably, the light conversion glass tube is made by a high temperature melting method, and its constituent raw materials include H 3 BO 3 、Al 2 O 3 、SiO 2 、ZnO、BaCO 3 and Ce 2 O 3 The light conversion glass tube is a transparent hollow circular tube with a thickness of 2 mm and an outer diameter of 30 mm. The advantage is that the narrow-band ultraviolet light emitted by the LED lamp beads is converted into 340-400nm broadband ultraviolet light after passing through the light conversion glass tube, which can attract a variety of pests and improve the efficiency of attracting insects.

[0007] Preferably, the convex lens is formed by connecting a plurality of plano-convex lenses whose number is equal to that of the LED lamp beads, the focal point of the plano-convex lens coincides with the position of the LED lamp beads, the convex surface of the plano-convex lens faces outward, and the flat surface of the plano-convex lens faces inward. The advantage is that the light emitted by the LED lamp beads is converged after passing through the convex lens, thereby improving the luminous efficiency and further improving the insect attracting efficiency.

[0008] Preferably, the light panel is in the shape of an equilateral triangular prism, and the three corners of the triangular prism are rounded. This is beneficial in that the light emitted by the LED lamp beads can cover the entire inner wall of the light conversion glass tube.

[0009] Compared with the prior art, the beneficial effects of the utility model are:

[0010] The utility model converts the narrow-band ultraviolet light emitted by the LED lamp beads into 340-400nm broadband ultraviolet light by introducing a light conversion glass tube, thereby effectively solving the problem of the narrow spectrum of the LED insect attractant lamp. The original 320nm light energy can attract flat grain beetles, but after conversion by the light conversion glass tube, broadband ultraviolet light with a wavelength of 340-400nm is obtained, which can attract caterpillar moths, yellow-striped flea beetles, red flat grain beetles, Turkish flat grain beetles, grass borers, black spiny whiteflies, Asian citrus psyllids, West Indian sweet potato weevils, tobacco beetles, Culicoides, cotton bollworms, tea geometrid caterpillars, green stink bugs, and Ailanthus altissima ditch weevils, thereby greatly improving the insect attracting efficiency. In addition, by introducing a convex lens, the point light source emitted by the LED lamp beads is converged into parallel light, thereby improving the luminous efficiency of the lamp tube.
