[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is in no way intended to limit the present invention and its application or use. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] like Figures 1 to 5 As shown, the present application provides a bracket for an LED module. An embodiment of the bracket of the present application includes: a bracket body 10 and a connecting base 20. The connecting base 20 includes a base 21 and exhaust ribs 22. The base 21 is provided on the bracket body 10. The base 21 protrudes forward from the front surface of the bracket body 10 and protrudes backward from the rear surface of the bracket body 10. The base 21 is provided with a connecting hole 211 that passes through the rear surface of the base 21. The connecting hole 211 is used to pass a fastener that fixes the bracket to the box. The exhaust ribs 22 are connected between the outer surface of the base 21 and the front surface of the bracket body 10.

[0028] Applying the technical solution of this embodiment, the base 21 of the connecting base 20 is provided with a connection hole 211 that passes through its rear surface. The bracket can be fixed to the box body by a fastener (such as a screw) passing through the connection hole 211. The base 21 forms the main load-bearing component for connecting the bracket and the box body. Exhaust ribs 22 are provided on the outer surface of the base 21. The provision of the exhaust ribs 22 can change the formation position of the weld line, so that the weld line is mainly formed on the non-load-bearing exhaust ribs 22, that is, there is no weld line or only a small number of weld lines on the base 21, the main load-bearing component for connecting the bracket and the box body, so that the base 21 is not easy to collapse during use, thereby ensuring the stability of the connection between the bracket and the box body. In addition, the provision of the exhaust ribs 22 can increase the strength of the connecting base 20, increase the service life of the connecting base 20, and further ensure the stability of the connection between the bracket and the box body. Therefore, the technical solution of this embodiment can effectively solve the problem of poor connection stability between the bracket and the box body in the related art.

[0029] It should be noted that the above “the exhaust ribs 22 are connected to the outer surface of the seat body 21 ” refers to the exhaust ribs 22 being connected to the circumferential outer surface of the seat body 21 .

[0030] Specifically, the bracket of the LED module is formed by injection molding. During the injection molding process, when two or more streams of molten injection molding material converge, a weld line may form at the intersection due to inconsistent temperatures, pressures, and flow rates. In this embodiment, vent ribs 22 are provided on the outer surface of the base 21. These vent ribs 22 ensure that the convergence of the molten injection molding material is squeezed into the ribs 22 and does not remain on the base 21, thereby changing the location of the weld line.

[0031] The LED module also includes a light board arranged on the bracket. Figure 1 As shown, when describing the bracket of this embodiment, the "front" used refers to the side where the bracket is connected to the light board, and the "rear" used refers to the side where the bracket is connected to the box.

[0032] Preferably, in this embodiment, the connection hole 211 is a through-hole structure that passes through the front and rear surfaces of the base body 21 .

[0033] like Figure 3 and Figure 4 As shown, the connection base 20 includes a plurality of venting ribs 22, which are evenly arranged along the outer circumference of the base body 21. The provision of the plurality of venting ribs 22 forms multiple points for the molten injection material to intersect and squeeze into during the injection molding process, thereby minimizing the number of weld lines formed on the base body 21 and ensuring that the base body 21 is not easily broken during use.

[0034] In this embodiment, the connecting base 20 includes a plurality of exhaust ribs 22 , and the number of the exhaust ribs 22 is greater than or equal to 4 and less than or equal to 6.

[0035] Specifically, if Figure 3 and Figure 4 As shown, in this embodiment, one connecting seat 20 has four exhaust ribs 22 , and each exhaust rib 22 extends along the radial direction of the seat body 21 .

[0036] like Figure 3 and Figure 4 As shown, the exhaust ribs 22 are flush with or lower than the front surface of the base 21, and the distance between the front surface of the exhaust ribs 22 and the front surface of the base 21 is greater than or equal to 0 mm and less than or equal to 0.5 mm. Preferably, the distance between the front surface of the exhaust ribs 22 and the front surface of the base 21 can be 0 mm, 0.2 mm, 0.3 mm, or 0.5 mm.

[0037] In this embodiment, the width of the vent ribs 22 is greater than or equal to 1.2 mm and less than or equal to 1.8 mm, and the length of the vent ribs 22 is greater than or equal to 2 mm and less than or equal to 2.8 mm. Specifically, the width of the vent ribs 22 refers to the dimension of the vent ribs 22 in the tangential direction of the base 21, and the length of the vent ribs 22 refers to the dimension of the vent ribs 22 in the radial direction of the base 21. Preferably, the width of the vent ribs 22 can be 1.2 mm, 1.5 mm, or 1.8 mm; the length of the vent ribs 22 can be 2 mm, 2.4 mm, or 2.8 mm.

[0038] like Figure 3 and Figure 4 As shown, the connection base 20 also includes a reinforcement ring 23 disposed between the outer surface of the base 21 and the front surface of the bracket body 10. The longitudinal cross-section of the reinforcement ring 23 is triangular. The reinforcement ring 23 surrounds the base 21, with one right-angled side of the triangular cross-section connected to the base 21 and the other right-angled side connected to the front surface of the base bracket body 10. The provision of the reinforcement ring 23 not only increases the structural strength of the connection base 20, thereby ensuring the stability of the connection between the bracket and the box, but also prevents the formation of sharp corners at the connection between the connection base 20 and the bracket body 10, which could cause stress concentration.

[0039] Specifically, in this embodiment, the height and / or width of the longitudinal cross-section of the reinforcement ring 23 is greater than or equal to 1 mm and less than or equal to 1.5 mm. The height of the longitudinal cross-section refers to the dimension of the cross-section in the front-to-back direction of the stent, and the width of the longitudinal cross-section refers to the dimension of the cross-section in the radial direction of the base 21. Preferably, the height and width of the longitudinal cross-section of the reinforcement ring 23 can be 1 mm, 1.2 mm, 1.3 mm, or 1.5 mm.

[0040] like Figure 4As shown, the reinforcement ring 23 has a connecting bevel 231 connecting between the base 21 and the bracket body 10. The angle between the connecting bevel 231 and the front surface of the bracket body 10 is greater than or equal to 40° and less than or equal to 50°. Preferably, the angle can be 40°, 45° or 50°.

[0041] In a preferred embodiment, the height and width of the longitudinal cross section of the reinforcement ring 23 are equal, that is, the angle between the connecting inclined surface 231 and the front surface of the bracket body 10 is 45°.

[0042] like Figure 1 and Figure 3 As shown, in this embodiment, the bracket has a plurality of connection seats 20 , and the plurality of connection seats 20 are arranged at intervals along the circumferential direction of the bracket body 10 .

[0043] In this embodiment, the rear surface of the base 21 has a texture. By providing the texture on the rear surface of the base 21, the corresponding positions of the mold used to manufacture the bracket also need to be provided with concave and convex structures to form the texture. When the molten injection molding material flows through these concave and convex structures, it flows more evenly, thereby achieving more uniform degassing, with little or no air being trapped. This makes it less likely that a weld line will form on the portion of the base 21 located behind the bracket body 10, thereby ensuring that the base 21 is not easily damaged.

[0044] Specifically, the texture on the rear surface of the base body 21 can be achieved by providing spark patterns or etching leather patterns at corresponding positions of the mold.

[0045] like Figure 1 and Figure 2 As shown, the outer surface of the portion of the base body 21 that protrudes rearward from the bracket body 10 comprises a first arcuate segment 212, a first planar segment 213, a second arcuate segment 214, and a second planar segment 215 that are sequentially connected. In other words, the cross-section of the portion of the base body 21 that protrudes rearward from the bracket body 10 is a non-circular structure, thereby increasing the structural strength of this portion of the base body 21.

[0046] It should be noted that when the exhaust ribs 22, the reinforcement ring 23 and the texture on the rear surface of the base body 21 in this embodiment are not provided, weld lines are easily formed on the first plane segment 213 and the second plane segment 215. When the above-mentioned structure is provided, the weld lines will be transferred to the exhaust ribs 22, so that there are no weld lines or only a few weld lines on the base body 21, which is the main load-bearing component for connecting the bracket and the box body. In this way, the base body 21 is not easy to collapse during long-term use.

[0047] like Figure 1 and Figure 3As shown, the bracket further includes reinforcing ribs 30 provided on the front surface of the bracket body 10 and / or the rear surface of the bracket body 10. Specifically, in this embodiment, the bracket body 10 is a flat plate structure, comprising an annular plate and connecting plates connected to the interior of the annular plate in a crisscross pattern; the reinforcing ribs 30 are provided on the flat plate-shaped bracket body 10, and include a first annular rib connected to the inner surface of the annular plate, a second annular rib connected to the outer surface of the annular plate, a first connecting rib located between the first and second annular ribs and arranged in a crisscross pattern, and a second connecting rib provided corresponding to the connecting plates.

[0048] Among them, such as Figure 3 and Figure 4 As shown, part of the first connecting ribs forms a cross structure on the front surface of the seat body 21 , and this part of the first connecting ribs can also play a role in changing the formation position of the weld line and increasing the structural strength of the connecting seat 20 .

[0049] Preferably, the front and rear surfaces of the bracket body 10 are both provided with reinforcing ribs 30. By combining the bracket body 10 with the reinforcing ribs 30, the bracket body 10 does not have any particularly thick parts while ensuring the structural strength of the bracket, thereby preventing shrinkage during the injection molding cooling process.

[0050] like Figure 5 As shown, the rear surface of the base 21 protrudes from the rear surface of the reinforcing rib 30. The rear surface of the base 21 abuts against the corresponding position on the box body, thereby ensuring the flatness of the bracket installed on the box body.

[0051] The present application also provides an LED module. Embodiments of the LED module of the present application include a bracket, which is the bracket described above. The bracket described above can effectively solve the problem of poor connection stability between the bracket and the housing in the related art. The LED module having the bracket described above also has the aforementioned advantages.

[0052] The present application also provides an LED housing. Embodiments of the LED housing include a housing and an LED module connected to the front of the housing. The LED module is the aforementioned LED module. The aforementioned LED module effectively addresses the problem of poor connection stability between the bracket and the housing in related art. An LED bracket equipped with the aforementioned LED module also possesses the aforementioned advantages.
