Description

Technical Field

[0001] This utility model relates to a mosquito trapping device, and more particularly to a mosquito-attracting lamp tube. Background Technology

[0002] In existing technologies, mosquito-killing lamps generally use a single wavelength of ultraviolet light as the mosquito-attracting light source. The mosquito-attracting principle is based on the phototaxis of mosquitoes to ultraviolet light of a specific wavelength. However, different types of mosquitoes have different phototaxis sensitivity wavelengths, and a single wavelength can only be effective for some mosquitoes, resulting in a limited mosquito-attracting range and poor overall effect.

[0003] There is also a dual-wavelength mosquito-killing lamp tube on the market. It mainly has two strings of ultraviolet lamps with different wavelengths installed inside the lamp tube. Therefore, the mosquito-killing lamp tube has two ultraviolet light sources. Because the two strings of lamps are different, the mosquito-killing lamp tube will emit two distinct ultraviolet lights in parallel, resulting in uneven light output from the entire ultraviolet lamp string. Utility Model Content

[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0026] It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this invention.

[0027] The following describes some embodiments of the present invention with reference to the accompanying drawings.

[0028] Reference Figures 1 to 5An enhanced mosquito-attracting lamp tube based on multispectral composite technology includes a lamp cover 1. The lamp cover 1 contains a light strip 2, on which several LED chip groups 3 are mounted. Each LED chip group 3 includes a first LED chip 31 emitting ultraviolet light at a wavelength of 365nm, a second LED chip 32 emitting ultraviolet light at a wavelength of 395nm, and a third LED chip 33 emitting ultraviolet light at a wavelength of 405nm. The first LED chip 31, the second LED chip 32, and the third LED chip 33 are connected in parallel and electrically connected to the electrodes at both ends of the light strip 2. In this embodiment, three LED chips with different ultraviolet light wavelengths are used. Different LED chips have a strong attraction to their respective types of mosquitoes, attracting various mosquitoes and thus killing most of them. The lamp cover is arranged in a spatially uniform distribution or spectral superposition manner to form mixed ultraviolet light with wavelengths of 365nm, 395nm, and 405nm, thereby improving the trapping rate.

[0029] The ratio of the first LED chip 31, the second LED chip 32, and the third LED chip 33 is 1:1:1. In this embodiment, the first LED chip 31, the second LED chip 32, and the third LED chip 33 all use existing technology to emit ultraviolet light at wavelengths of 365nm, 395nm, and 405nm. The first LED chip 31, the second LED chip 32, and the third LED chip 33 are combined to form a composite mosquito-attracting light source with three wavelengths. Compared with the prior art, this application integrates chips of three different wavelengths onto a single light strip, reducing the number of light strips. On the one hand, this reduces the overall cost of the mosquito-killing lamp tube; on the other hand, the light strip 2 can emit mixed light with three wavelengths, avoiding the emission of three distinct ultraviolet lights due to different wavelengths, resulting in more uniform light emission. Even if mosquitoes have individual differences in their sensitivity to the wavelength of the light source, it can still effectively attract them, improving the trapping rate.

[0030] In this invention, a plurality of first LED chips 31, second LED chips 32, and third LED chips 33 are arranged continuously or alternately along the length of the light strip. Specifically, the first LED chips 31, second LED chips 32, and third LED chips 33 can be arranged continuously in a front-to-back order, closely adjacent to each other, to form an LED chip group 3. Figure 3 As shown, the superposition of these three spectral bands forms a composite mosquito-attracting light source with three spectral bands; if the three LED chips are arranged alternately, then the three LED chips need to be arranged alternately, such as... Figure 5 As shown, the light from these three wavelengths can be evenly distributed inside the lampshade.

[0031] In this embodiment, several LED chip groups 3 are connected in parallel in sequence. The negative terminal of each LED chip group 3 is grounded to GND, and the positive terminal is connected to the power supply VCC. A filter circuit is provided between the power supply VCC and the ground GND. The filter circuit consists of a Zener diode ZD1, a resistor R1, and a capacitor C1 to ensure that the operation of the light strip is more stable.

[0032] The bottom of the lampshade 1 is coated with an adhesive layer 11 for adhering the light strip 2, and the two end faces of the lampshade 1 respectively abut against the two sides of the light strip 2. In this embodiment, the adhesive layer 11 is thermally conductive silicone, which can fix the light strip inside the lampshade 1 while quickly conducting and dispersing the heat generated by the light strip.

[0033] The lampshade 1 has plugs 12 installed at both ends. One side of each plug 12 has a connector 13 that conforms to the shape of the lampshade 1. After assembly, the connector 13 is inserted into the lampshade 1, resulting in a simple assembly structure. In this embodiment, an electric needle is provided on the outside of the plug 12. The electric needle passes through the connector 13 and is electrically connected to the lamp strip 2.

[0034] The lampshade 1 is a light-transmitting glass tube or a quartz glass tube, which gives the light extremely high hardness and transparency, and also has the advantages of high temperature resistance, wear resistance and oxidation resistance.

[0035] Reference Figures 6 to 8 An enhanced mosquito-attracting lamp tube based on multispectral composite technology includes a lampshade 1, a light strip 2 installed inside the lampshade 1, and several fourth LED chips 21 emitting ultraviolet light with a wavelength of 254nm installed on the light strip 2. A light guide 4 is installed on the inner wall of the lampshade 1 to uniformly guide the light emitted by the several fourth LED chips 21. The inner wall of the light guide 4 is coated with phosphors that can emit ultraviolet light with wavelengths of 365nm, 395nm, and 405nm respectively. In this embodiment, the fourth LED chips 21 serve as an excitation light source, which can excite the phosphors on the light guide 4 to emit ultraviolet light with wavelengths of 365nm, 395nm, and 405nm. The three ultraviolet light wavelengths are combined and arranged in a spatially uniform distribution or spectral superposition manner within the light guide 4 to form mixed ultraviolet light with wavelengths of 365nm, 395nm, and 405nm, thereby expanding the types and range of mosquitoes attracted and improving the trapping rate.

[0036] In this embodiment, the phosphor is a readily available fluorescent material capable of emitting 365nm, 395nm, and 405nm ultraviolet light, and the three phosphors can be mixed in a 1:2:1 ratio. In this embodiment, the fourth LED chip 21 uses existing technology to emit LED beads with an ultraviolet light wavelength of 254nm.

[0037] The bottom of the light guide cover 4 is coated with an adhesive layer 11 for adhering the light strip 2. The light guide cover 4 is attached to the inner wall of the lamp cover 1, and the two end faces of the light guide cover 4 respectively abut against the two sides of the light strip 2. The assembly structure is simple.
