Description

Technical Field

[0001] This utility model relates to the field of detection light sources, and in particular to a dustproof linear light source. Background Technology

[0002] Traditional manufacturing has always pursued the standardization of parts, and this trend is equally applicable to non-standard industries. Improving the standardization of products can effectively improve product production efficiency and versatility.

[0003] The existing linear light structure is not very versatile, and many additional parts need to be processed during the assembly process. The processing errors of the parts reduce production efficiency, and the gaps between the workpieces reduce the efficiency of heat transfer of the light source. Utility Model Content

[0004] The purpose of this utility model is to overcome the above-mentioned defects in the prior art and provide a dustproof linear light source. The light source body is integrally formed and multiple mounting grooves are formed in the light source body to further increase the material versatility between light sources and reduce production difficulty. The heat dissipation effect is further improved by increasing the contact area between the circuit board and the body.

[0005] To achieve the above objectives, this utility model provides a dustproof linear light source, including...

[0006] The light source body is integrally formed, with a first mounting cavity formed at the upper end of the light source body, a first mounting groove provided at the bottom of the first mounting cavity, a second mounting cavity provided in the middle of the light source body, a third mounting cavity provided at the lower part of the light source body that communicates with the second mounting cavity, and a light outlet provided at the lower end of the light source body, with a transparent plate provided on the light outlet.

[0007] A plurality of cooling fans are installed in the first mounting cavity, and the cooling fans are detachably connected to the first mounting slot.

[0008] A light source circuit board, which is detachably installed in the second mounting cavity and is in close contact with the inner wall of the second mounting cavity;

[0009] The lens assembly is detachably installed in the third mounting cavity.

[0010] Furthermore, a first mounting hole is provided on the cooling fan, the position of which matches the position of the first mounting slot, and a gap is provided between two adjacent cooling fans. The first mounting hole is integrally formed by the light source body, and the cooling fan can be fixed with a bracket simply by screws, which is simple, convenient and easy to operate.

[0011] Furthermore, a heat dissipation cavity communicating with the first mounting cavity is provided below the first mounting cavity, and the heat dissipation cavity is provided with multiple sets of evenly arranged heat dissipation fins. The heat dissipation fins can better improve the heat dissipation effect.

[0012] Furthermore, a flow space is formed between the upper end of the heat dissipation fin and the cooling fan, and the end of the heat dissipation fin is adjacent to the light source circuit board. By pre-setting a certain flow space, the air blown by the cooling fan can circulate between the heat dissipation fins, thereby improving its heat dissipation effect.

[0013] Furthermore, the lens assembly includes a first lens and a second lens, and a second mounting groove and a third mounting groove are sequentially arranged from top to bottom on the third mounting cavity. The first lens and the second lens are sequentially inserted into the second mounting groove and the third mounting groove. Using two lenses enhances the overall uniformity of light, and the insertion method makes the lens assembly easier to install.

[0014] Furthermore, the system also includes a cover plate, with the light outlet located in the center of the cover plate. The lower end of the cover plate has a mounting portion surrounding the light outlet. A light guide portion gradually slopes outwards between the light outlet and the mounting portion. A fourth mounting groove is provided on the light source body, and the mounting portion is detachably connected to the fourth mounting groove via screws. The cover plate assists in the installation of the transparent plate and protects the internal components, ensuring that the light guide portion does not affect light output and improving overall stability.

[0015] Furthermore, the lower end of the light source body is provided with a fifth mounting groove, and the transparent plate is installed in the fifth mounting groove and abuts against the cover plate. The transparent plate is directly installed in the fifth mounting groove, and then the cover plate is used to clamp and position the transparent plate, thus achieving the installation of the transparent plate without the need for other auxiliary parts, optimizing its structure and reducing costs.

[0016] Furthermore, a sixth mounting groove is formed on the inner wall of the fifth mounting groove, and a sealing ring is installed in the sixth mounting groove, the sealing ring tightly abutting against the transparent plate. Installing the sealing ring improves the sealing performance of the assembled transparent plate, effectively enhancing dust and water resistance and improving the stability of the light source.

[0017] Furthermore, an optical film is adhered to the inner side of the transparent plate. The optical film further scatters the emitted light, distributing the light emitted from a point source or small area source evenly across the entire transparent plate, resulting in more uniform brightness of the light emitted from the transparent plate across the entire light-emitting surface.

[0018] Furthermore, it also includes two side panels, and a seventh mounting slot is provided through the left and right sides of the light source body. The side panels are detachably connected to the seventh mounting slot via screws. By providing side panels, the installation and protection of various components can be facilitated. Moreover, the seventh mounting slot is also integrally formed with the light source body, which can further reduce the need for other installation structures and reduce processing costs.

[0019] Compared with the prior art, this utility model has the following advantages: This utility model mainly solves the problems of insufficient contact area between the circuit board and the main body of the linear light source, and the large number of processing parts required for connecting standard parts, electrical components and the housing. It simplifies the circuit board mounting strip and the fan mounting strip into concave mounting grooves, which can be installed using self-tapping screws. This increases the contact area between the circuit board and the light source body, improves heat dissipation efficiency, and further enhances the heat dissipation effect. At the same time, it eliminates the need to add processing dimensional tolerances in the length direction, reducing processing costs. It also eliminates the restriction on screw hole positions in the length direction, which can standardize and universalize this type of linear light source, further increasing the material commonality between light sources and reducing production difficulty.

If the specific posture changes, the directional indicator will also change accordingly.

[0031] Furthermore, if the embodiments of this utility model involve descriptions such as "first" or "second", such descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated.

[0032] Please see Figures 1 to 5 The present invention provides a dustproof linear light source, including a light source body 1, several cooling fans 2, a light source circuit board 3, a lens group 4, two side plates 5, and a cover plate 6.

[0033] In this embodiment, the light source body 1 is integrally formed from a thermally conductive material. This thermally conductive material can be aluminum, copper, aluminum alloy, copper alloy, or other thermally conductive materials with good thermal conductivity, such as... Figure 1 and Figure 2 As shown, a first mounting cavity 11 is formed at the upper end of the light source body 1, and a first mounting groove 12 is provided at the bottom of the first mounting cavity 11. The cooling fan 2 is installed in the first mounting cavity 11, and as shown... Figure 3As shown, first mounting holes 21 are provided at the four corners of the cooling fan 2. The positions of the first mounting holes 21 match the positions of the first mounting slots 12. During assembly, it is only necessary to directly connect the self-tapping screws through the first mounting holes 21 and the first mounting slots 12. In this embodiment, a total of four cooling fans 2 are provided. A gap 22 is provided between two adjacent cooling fans 2 to form a flow channel for completing heat exchange air, which can effectively improve the heat dissipation effect.

[0034] like Figure 2 As shown, a heat dissipation cavity 13 communicating with the first mounting cavity 11 is also provided below the first mounting cavity 11. The heat dissipation cavity 13 is provided with multiple sets of evenly arranged heat dissipation fins 14. Preferably, in this embodiment, a flow space 7 is formed between the upper end of the heat dissipation fin 14 and the cooling fan 2. As shown, this can increase the flow space of the cooling air and form a good heat dissipation flow channel, thereby improving the heat dissipation effect.

[0035] A second mounting cavity 15 is provided in the middle of the light source body 1. The light source circuit board 3 is detachably mounted in the second mounting cavity 15 and is tightly attached to the inner wall of the second mounting cavity 15. Figure 2 As shown, an eighth mounting groove 151 is provided on the upper wall of the second mounting cavity 15. The light source circuit board 3 can be directly connected and fixed with self-tapping screws. At this time, the light source circuit board 3 will be in close contact with the upper wall of the second mounting cavity 15. As can be seen from the figure, when the light source circuit board 3 is locked, it is placed directly below the heat dissipation fin 14 and adjacent to it. The two are separated by the wall of the light source body 1. This not only increases the contact area between the light source circuit board 3 and the light source body 1 and improves the efficiency of heat transfer, but also allows for better cooperation with the heat dissipation fin 14 and the cooling fan 2, thereby improving the heat dissipation effect.

[0036] The lower part of the light source body 1 is provided with a third mounting cavity 16 that communicates with the second mounting cavity 15. The lens group 4 can be detachably installed in the third mounting cavity 16. Specifically, the lens group 4 includes a first lens 41 and a second lens 42. A second mounting groove 161 and a third mounting groove 162 are arranged sequentially from top to bottom on the third mounting cavity 16. The first lens 41 and the second lens 42 can be inserted into the second mounting groove 161 and the third mounting groove 162 in sequence.

[0037] To enhance the sealing and dustproof function of the light source body 1, this embodiment also includes two side plates 5. A seventh mounting groove 17 is provided through the left and right sides of the light source body 1. In this embodiment, a total of three sets of seventh mounting grooves 17 are provided, respectively located at the upper, middle and lower ends of the light source body 1. The side plates 5 are detachably connected to the seventh mounting grooves 17 by screws. The two side plates 5 are used to seal the two sides of each mounting cavity and also to lock the left and right ends of the lens group 4 to prevent it from falling off.

[0038] The lower end of the light source body 1 has a light outlet 61, and a transparent plate 8 is provided on the light outlet 61. An optical film 81 is adhered to the inner side of the transparent plate 8. Specifically, as shown in the figure... Figure 6 The light outlet 61 is located in the middle of the cover plate 6. The lower end of the cover plate 6 is provided with a mounting part 62 surrounding the light outlet 61. A light guide part 63 is formed between the light outlet 61 and the mounting part 62, which gradually slopes from the inside to the outside. A fourth mounting groove 10 is provided on the light source body 1. The mounting part 62 is detachably connected to the fourth mounting groove 10 by a screw.

[0039] To facilitate the installation of transparent panel 8, such as Figure 2 and Figure 4 As shown, a fifth mounting groove 18 is provided at the lower end of the light source body 1. The transparent plate 8 is installed in the fifth mounting groove 18 and abuts against the cover plate 6. During assembly, the transparent plate 8 is placed into the fifth mounting groove 18, and then the cover plate 6 is locked. It should be noted that the size of the transparent plate 8 is larger than the size of the light outlet 61, so that after the cover plate 6 is locked, the cover plate 6 can press the transparent plate 8 tightly and will not fall off from the light outlet 61.

[0040] In some preferred embodiments, a sixth mounting groove 19 is formed on the inner wall of the fifth mounting groove 18, and a sealing ring 9 is installed in the sixth mounting groove 19, which abuts tightly against the transparent plate 8. Installing the sealing ring 9 improves the sealing performance of the transparent plate 8 after assembly, effectively enhancing dust and water resistance and improving the stability of the light source.

[0041] In summary, the working principle of this utility model is as follows: When in use, this utility model is directly connected to the detection system; simply turn on the light source to use it. The light source body 1 of this utility model adopts a one-piece structure directly formed from thermally conductive metal. The light source body 1 contains cavities and grooves for mounting components. During assembly, each component can be directly installed in its corresponding position using automatic screws, without the need for additional modifications or the addition of other connecting components, thereby reducing overall production costs. Regarding heat dissipation, the light source circuit board 3 is mounted through the second mounting cavity 15, allowing it to fit snugly against the light source body 1. Only an eighth mounting groove 151 is provided to facilitate the installation of the light source circuit board 3, effectively increasing the contact area between the light source circuit board 3 and the light source body 1. This allows the heat from the light source circuit board 3 to be transferred through the light source body 1 to the heat dissipation fins 14, where it exchanges heat with the airflow from the cooling fan 2 in the heat dissipation cavity 13 and the first mounting cavity 11, achieving excellent heat dissipation. Furthermore, the one-piece structure of the light source body 1, along with the use of side plates 5 and a cover plate 6 in conjunction with a sealing ring 9, provides dust and water protection for the interior of the light source circuit board 3.

[0042] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
