Description

Technical Field

[0001] This utility model relates to the technical field of light source devices for industrial testing, and in particular to a strip light source for detecting pharmaceutical solutions. Background Technology

[0002] The principle of drug liquid detection light source is mainly based on optical absorption, fluorescence reaction or light scattering effect. It detects components or defects by irradiating the drug liquid with light of a specific wavelength and analyzing its optical properties.

[0003] Optical absorption utilizes a D65 combined LED light source (simulating natural sunlight, wavelength 360-780nm). When the drug solution is irradiated, the pigments or solutes in the solution absorb light of specific wavelengths. The degree of absorption is directly proportional to the concentration and optical path length (Lambert-Beer Law). The composition or concentration is determined by measuring the transmittance or absorbance.

[0004] Fluorescence reactions utilize ultraviolet light sources (such as UV lamps) that emit ultraviolet light of specific wavelengths. When a liquid drug is irradiated, if a substance that can absorb ultraviolet light and release fluorescence (such as pesticide residues) is present, it will emit visible fluorescence. By detecting differences in fluorescence intensity or wavelength, specific components can be identified.

[0005] Light scattering effect utilizes the difference in absorption of ultraviolet light by substances, or a refractive index detector detects all substances by changes in the refractive index. It is suitable for the detection of samples with lower volatility than the mobile phase.

[0006] The main structure of existing drug detection light sources is usually manufactured by CNC machining of aluminum alloy, which is costly and requires secondary processing, resulting in low efficiency. Utility Model Content

[0036] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0037] Example 1

[0038] In view of the aforementioned defects in existing light sources, the applicant, based on years of extensive practical experience and professional knowledge in the design and manufacture of such products, and in conjunction with the application of theoretical principles, has actively conducted research and innovation in order to create a technology that can overcome the defects in the existing technology and make the light source more practical. After continuous research, design, and repeated prototype production and improvement, this utility model with real practical value has finally been created.

[0039] Please refer to Figure 1 and Figure 2 This utility model provides a strip light source for detecting drug solutions, comprising:

[0040] Main body 1, which is a one-piece molded U-shaped structure;

[0041] Light panel 2 is installed inside the main body 1;

[0042] Diffuser plate 3 is positioned in the light-emitting direction of lamp plate 2, and the diffuser plate 3 closes the upper end face of the U-shaped opening of the main body;

[0043] The plug 4 has two plugs, which are respectively set on the two side ends of the U-shaped opening of the main body to close the two side ends of the main body. Together with the diffuser plate 3, they form a closed space inside the main body.

[0044] The plug 4 has a first screw hole 41, and a second screw hole 13 is provided on the main body 1 at the corresponding position. A screw passes through the first screw hole 41 and is then assembled into the second screw hole 13 on the main body 1, fixing the plug 4 to the main body 1. The plug 4 can be manufactured using a die-casting process. Die-casting involves rapidly forming molten metal by injecting it into a mold under high pressure; it is a hot-working process suitable for metals such as copper, zinc, and aluminum. Die-cast parts have high density, making them suitable for drilling. By die-casting the plug 4 into a standard part that matches the main body 1, rapid assembly can be achieved. (Reference) Figure 1 The upper end of the plug 4 extends inward to form a baffle 42. The baffle 42 is fastened to the upper end face of the two sides of the diffuser plate 3. The baffle 42 protects the two end faces of the diffuser plate and makes the overall structure more aesthetically pleasing.

[0045] It should be noted that in this embodiment, the main body 1 is a stretched part produced by a stretching process. A stretched part is produced by plastically deforming a metal billet through a die composed of a punch and a die under external force, causing the billet to elongate axially and contract radially, thereby obtaining a stretched part of a specific shape and size. After obtaining the stretched part of a specific shape and size, it is then cut to the required length to form the main body required by this invention, enabling high-efficiency mass production. The main body 1, together with the standard plug 4, constitutes the assembly housing of the light source, which has a significant cost advantage compared to housings produced by existing CNC integrated machining. In other embodiments, the main body 1 can also be made by die casting. Compared to stretched parts, die casting is slightly more expensive, but it still has a significant cost advantage compared to CNC integrated machining.

[0046] refer to Figure 2The diffuser plate 3 is arranged parallel to the lamp plate 2 and is positioned in the light-emitting direction of the lamp plate 2. The light emitted from the lamp plate 2 can be fully directed onto the diffuser plate 3, improving light utilization. The diffuser plate 3 scatters the received light before directing it onto the liquid being tested, resulting in more uniform light illumination of the liquid.

[0047] refer to Figure 1 In this embodiment, the lamp board 2 includes a PCB substrate 21 and LED beads 22 arranged on the PCB substrate 21. The LED beads are infrared LED beads, which are uniformly and densely arranged on the PCB substrate. The infrared wavelength accuracy can be precisely controlled, and specific infrared bands can be selected according to actual applications: 700-1000nm near-infrared band, 1000-3000nm mid-infrared band, and far-infrared band above 3000nm. Near-infrared band is used to identify surface details, while far-infrared band is used to detect object temperature. Infrared light has strong anti-interference ability. The infrared band is invisible light, which can avoid interference from ambient light and illumination light, making it suitable for application scenarios with complex lighting environments. It has penetrating and high recognition characteristics, and can penetrate some semi-transparent materials to highlight subtle differences on the surface of objects, features that cannot be captured by visible light. Using high-density infrared LED beads as the light source, the high penetrating power of high-density infrared LEDs, combined with a diffuser plate, can reduce shadows and make the liquid image uniform.

[0048] refer to Figure 3 The inner wall of the main body 1 has a first slot 11 corresponding to the position of the diffuser plate; the inner wall of the main body 1 has a second slot 12 corresponding to the position of the lamp plate; the diffuser plate 3 is engaged in the first slot 1; the lamp plate 2 is engaged in the second slot 12. Besides the engaging connection method, the diffuser plate 3 can also be assembled into the main body 1 by welding, gluing, or threaded connection. Similarly, the lamp plate 2 can be assembled into the main body 1 by welding, gluing, or threaded connection.

[0049] The lamp plate 2 is positioned close to the bottom of the main body 1. Preferably, the main body 1 is made of a metal with good heat dissipation properties, such as aluminum alloy, which has good heat dissipation performance and good ductility, facilitating stretching and shaping. In a preferred embodiment, thermally conductive silicone can be provided between the lamp plate 2 and the main body 1. The thermally conductive silicone can better transfer the heat generated by the lamp plate 2 to the main body 1, thereby improving the heat dissipation efficiency of the lamp plate 2. In a preferred embodiment, a heat sink 14 is provided at the bottom of the main body 1, which can efficiently dissipate the heat inside the main body 1 to the outside.

[0050] refer to Figure 1 This embodiment also includes a light source line 5; a wire hole is provided on one of the plugs, and the light source line 5 passes through the wire hole and is electrically connected to the lamp board 2.

[0051] In this embodiment, both the main body and the end cap are manufactured using a uniformly set standard size. When assembly is required, the side plate is cut according to the size of the light source, which allows for flexible assembly of light sources of different lengths. Assembly is quick and requires no secondary processing, resulting in low cost.

[0052] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
