Description

Technical Field

[0001] This utility model relates to the field of lighting technology, specifically to a lamp frame and a lamp having the lamp frame. Background Technology

[0002] For a certain type of existing lighting fixture, the size of the fixture frame needs to be configured according to its power rating. Currently, there are two common methods for manufacturing lighting fixture frames: The first type, such as Figure 1 As shown, the outer frame 91 of the lamp is integrally die-cast using a die-casting method. However, this method has the following drawbacks: high investment cost, requiring the design of a mold of corresponding size for each type of lamp power; The second type, such as Figure 2 As shown, the lamp frame 92 is assembled by splicing multiple parts 921. Although this method has low investment cost, the parts need to be fixed and connected with fasteners, which is cumbersome and involves a large number of parts. If the fasteners become loose, there is a risk that the lamp frame will fall apart, resulting in poor long-term reliability. Utility Model Content

[0003] To address the aforementioned problems, the primary objective of this utility model is to provide a lamp frame that has low production costs, requires fewer assembly parts, and offers high long-term reliability.

[0004] The second objective of this utility model is to provide a lamp with the aforementioned lamp frame.

[0005] To achieve the first objective of this utility model, this utility model provides a lamp frame, which includes a profile frame and a lamp arm. The profile frame has a receiving cavity. The profile frame is formed by bending a long strip of profile. The profile has a first strip groove extending along its own extension direction. The first strip groove is located in the receiving cavity. The lamp arm is connected to the profile frame.

[0006] As can be seen from the above, by designing the profile frame, the profile can be cut to the corresponding length according to the power of the lamp (i.e. the number of light-emitting modules) and then bent to form the profile frame. This eliminates the need to design a mold of corresponding size for each type of lamp power, reducing production costs. Furthermore, it can minimize the number of components in the lamp frame, reduce assembly complexity, and improve the reliability of the profile frame and the overall lamp.

[0007] A further solution is to provide a clearance opening at the lamp arm of the profile frame; the lamp arm has a connecting part and a storage part, the connecting part is connected to the profile frame, and the storage part passes through the clearance opening and extends into the receiving cavity.

[0008] As can be seen from the above, the storage section can accommodate the connection terminal between the external power supply cable of the lamp and the light-emitting module, which can improve the reliability of the electrical connection between the external power supply cable and the light-emitting module, as well as the safety of the electrical connection; while the setting of the clearance opening allows the storage section to be inserted into the receiving cavity, thereby making better use of the redundant space inside the receiving cavity and reducing the volume of the lamp frame.

[0009] A further improvement is that the connecting part has a connecting rib, which is located outside the profile frame and connected to the profile frame.

[0010] As can be seen from the above, the connecting rib can improve the connection strength and reliability between the lamp arm and the profile frame, and make the connection between the lamp arm and the profile frame more convenient.

[0011] A further proposed solution is to have two connecting ribs, with the storage section located between the two connecting ribs; the lamp frame also includes two brackets, with the storage section located between the two brackets, the brackets located inside the receiving cavity, and one bracket connected to the profile frame and one connecting rib.

[0012] As can be seen from the above, setting the number of connecting ribs to two can improve the stability of the connection between the lamp arm and the profile frame; and since the profile frame is provided with a clearance for the storage part to pass through, the structural strength of the profile frame is affected. However, by adding a bracket, the structural strength of the profile frame can be improved, ensuring the reliability of the connection between the profile frame and the lamp arm.

[0013] A further proposed solution is that the profile includes an integrally formed hollow frame, an L-shaped plate, and a set of reinforcing ribs; the hollow frame has a side wall and a load-bearing part, the side wall has a step formed at the end away from the load-bearing part, the load-bearing part has a supporting surface, a part of the supporting surface is recessed into the load-bearing part to form a first groove; the L-shaped plate is located at the step, the bottom plate of the L-shaped plate is opposite to the supporting surface, the side plate of the L-shaped plate and the step form a second groove, the second groove extends along the extension direction of the profile; the set of reinforcing ribs is located inside the hollow frame.

[0014] As can be seen from the above, the hollow frame can significantly reduce the weight of the frame while ensuring the strength of the profile. The load-bearing part is used to support and limit the light-emitting module, and the light-emitting module is fixed with the first strip groove and fasteners. The step of the hollow frame cooperates with the cover plate to support and limit the cover plate, and forms a second strip groove with the L-shaped plate, so that the second strip groove can cooperate with the fasteners to fix the cover plate. The reinforcing ribs are used to improve the structural strength of the hollow frame and prevent the hollow frame from collapsing or deforming.

[0015] A further proposed solution is to have a first gap between the base plate and the support surface, the difference between the first gap and the height of the bracket being between 3 mm and 5 mm.

[0016] As can be seen from the above, this design limits the deformation of the profile frame at the corner of the lamp arm to between 0.15 mm and 0.25 mm, ensuring that the profile frame will not be damaged at the weak corner.

[0017] A further proposed solution is to have notches at all bends in the profile, with the notches being triangular and the apex of the triangles pointing towards the outer perimeter of the profile frame; after the profile is bent to form the profile frame, the bends are welded and fixed in place.

[0018] As can be seen above, the triangular notch design makes it easier to bend the profile, and the material itself will not be squeezed and deformed due to bending, which ensures both the structural strength and the aesthetics of the profile frame; while welding and fixing the bending point can improve the overall stability of the profile frame.

[0019] A further proposed solution is to have a second gap between the apex of the sharp corner and the outer peripheral surface, the second gap being between 1 mm and 2.5 mm.

[0020] As can be seen from the above, this design can ensure the continuity of the profile and the connection strength of the profile segments on both sides of the notch. On the other hand, it can ensure that when the profile is bent through the notch, the sharp corner of the triangular notch will not be squeezed and deformed, thus ensuring the structural strength and aesthetics of the profile frame.

[0021] To achieve the second objective of this utility model, this utility model provides a lamp, including a light-emitting module, which further includes the aforementioned lamp frame, the light-emitting module being disposed within a receiving cavity, and the light-emitting module being connected to a first strip groove.

[0022] As can be seen from the above, by configuring the lamp frame as described above, the production cost can be reduced, the number of parts can be reduced, the assembly complexity can be reduced, and the overall reliability of the lamp can be guaranteed.

[0023] A further embodiment is that the luminaire also includes a first cover plate, a second cover plate, and a power module. The first cover plate is connected to the first strip groove and covers part of the first opening of the receiving cavity. The second cover plate is connected to the outer frame of the luminaire and covers at least part of the second opening of the receiving cavity. The power module is located between the first cover plate and the second cover plate and is connected to the first cover plate or the second cover plate.

[0024] As can be seen from the above, the first cover plate and the second cover plate are used to cover the opening of the receiving cavity, and at the same time provide installation space for the power module, so as to further utilize the redundant space inside the receiving cavity.

[0035] The present invention will be further described below with reference to the accompanying drawings and embodiments. Detailed Implementation

[0036] Lighting Fixture Examples Reference Figure 3 and Figure 4 The lamp 100 includes a lamp frame 101, a light-emitting module 102, a first cover plate 103, a second cover plate 104, and a power module 105. The lamp frame 101 includes a profile frame 1 and a lamp arm 2, which is connected to the profile frame 1.

[0037] Combination Figure 5The profile frame 1 is formed by bending a long strip of profile 10. The profile frame 1 has a receiving cavity for accommodating components such as the light-emitting module 102 and the power module 105. Since the size of the profile frame 1 needs to be compatible with the power of the lamp 100 (i.e., the number of light-emitting modules 102), the size of the profile frame 1 can be controlled by adjusting the length of the profile 10. That is, the profile 10 can be cut to a corresponding length according to the power of the lamp 100 and then bent to form the profile frame 1. This eliminates the need to design a mold of a corresponding size for each power of the lamp 100, reduces production costs, minimizes the number of components in the lamp frame 101, reduces assembly complexity, and also improves the overall reliability of the profile frame 1 and the lamp 100.

[0038] Before bending, the profile 10 has multiple notches 11. These notches 11 are used for bending the profile 10 to ensure the bending quality of the profile 10 and the forming quality of the profile frame 1. Figure 6 The notch 11 is preferably triangular, with the sharp corner of the triangle facing the outer periphery of the profile frame 1. Designing the notch 11 as a triangle makes it easier to bend the profile 10, and also prevents the sharp corner of the triangle from being squeezed and deformed when the profile 10 is bent, thus ensuring the structural strength and aesthetics of the profile frame 1.

[0039] Furthermore, a second spacing W2 exists between the apex of the triangle and its outer periphery, preferably between 1 mm and 2.5 mm. This design ensures both the continuity of the profile 10 and the connection strength of the profile 10 segments on both sides of the notch 11, preventing the profile 10 from breaking at the notch 11. It also ensures that when the profile 10 is bent through the notch 11, no extrusion deformation or bulging occurs at the apex of the triangular notch 11, further guaranteeing the structural strength and aesthetics of the profile frame 1. Preferably, the second spacing W2 is 1 mm.

[0040] After the profile 10 is bent to form the profile frame 1, the bent area is welded to reinforce the stability of the profile frame 1 at the bend, thereby ensuring the overall stability of the profile frame 1. Furthermore, it is understood that, depending on the different bending angles and bending positions of each area of ​​the profile 10, the notches 11 are non-uniformly distributed on the profile 10, and the angle of the apex of the triangular notch 11 is set according to the magnitude of the bending angle (bending degree); the larger the bending angle, the larger the angle of the apex of the triangular notch 11.

[0041] In this embodiment, taking the center line of the profile frame 1 as a reference, the profile 10 is divided into left and right sides by the center line of symmetry. Therefore, the positions of the notches 11 on the left and right sides of the profile 10 and the positions of the left and right ends of the profile 10 are mirror-symmetrical about the center line of symmetry. However, it is understood that in some embodiments, the positions of the notches 11 on the left and right sides of the profile 10 and the positions of the left and right ends of the profile 10 are not mirror-symmetrical about the center line of symmetry.

[0042] The profile 10 includes an integrally formed hollow frame 12, an L-shaped plate 13, and a reinforcing rib assembly 14. The hollow frame 12 has a side wall portion 121 and a supporting portion 122, which are roughly L-shaped, such that the side wall portion 121 and part of the supporting portion 122 form the perimeter wall of the profile frame 1, and the remaining part of the supporting portion 122 forms the enclosure on the light-emitting side of the profile frame 1. A step 1211 is formed at the end of the side wall portion 121 away from the supporting portion 122. A portion of the step 1211 can be used to support and limit components such as the second cover plate 104, while the other portion of the step 1211 is used to cooperate with the L-shaped plate 13 to form a second strip groove 1311. The supporting portion 122 has a supporting surface 1221, a portion of which is recessed into the supporting portion 122 to form a first strip groove 1222.

[0043] L-shaped plate 13 is disposed at step 1211, wherein the bottom plate 132 of L-shaped plate 13 is disposed opposite to the supporting surface 1221, and the bottom plate 132 is preferably parallel to the supporting surface 1221. The side plate 131 of L-shaped plate 13 forms the aforementioned second strip groove 1311 with step 1211. It can be understood that when the profile 10 is in the unfolded state, the first strip groove 1222 and the second strip groove 1311 both extend along the extension direction of the profile 10 and penetrate the profile 10; when the profile 10 is connected end to end to form the profile frame 1, the first strip groove 1222 and the second strip groove 1311 are also connected end to end respectively to form a circular first strip groove 1222 and a circular second strip groove 1311.

[0044] The reinforcing rib group 14 preferably includes two or more reinforcing ribs, which are preferably arranged in parallel and parallel to the support surface 1221. The reinforcing rib group 14 can improve the structural strength of the hollow frame 12 and prevent the hollow frame 12 from collapsing or deforming.

[0045] The hollow frame 12 design can significantly reduce the weight of the profile frame 1 while ensuring the strength of the profile 10. The bearing part 122 is used to support and limit the light-emitting module 102. With the first strip groove 1222 and fasteners thereon, the light-emitting module 102 can be fixed on the profile frame 1 and the light-emitting module 102 is located in the receiving cavity. In addition to supporting and limiting the second cover plate 104, the step 1211 of the hollow frame 12 and the second strip groove 1311 formed with the L-shaped plate 13 can be used with fasteners to fix the second cover plate 104 on the profile frame 1.

[0046] Furthermore, the profile frame 1 has a clearance opening 15 at the lamp arm 2. In this embodiment, the clearance opening 15 is preferably located at the junction of the two ends of the profile 10. To accommodate the design of the clearance opening 15, the lamp arm 2 is designed with the following structure: Combination Figure 7 The lamp arm 2 has a connecting part 21 and a storage part 22. The lamp arm 2 is connected to the profile frame 1 through the connecting part 21. In addition, the lamp 100 can also be fixedly connected to an external lamp post through the connecting part 21 of the lamp arm 2. Preferably, the connecting part 21 has a connecting rib 211, which is located outside the profile frame 1 and connected to the profile frame 1. The setting of the connecting rib 211 can improve the connection strength and reliability between the lamp arm 2 and the profile frame 1, and make the connection between the lamp arm 2 and the profile frame 1 more convenient.

[0047] The storage section 22 passes through the clearance opening 15 and extends into the receiving cavity. The storage section 22 can accommodate the connection terminal between the external power supply cable of the lamp 100 and the light-emitting module 102. On the one hand, it can improve the reliability of the electrical connection between the external power supply cable and the light-emitting module 102, and on the other hand, it can improve the safety of the electrical connection. The clearance opening 15 allows the storage section 22 to be inserted into the receiving cavity, thereby making better use of the redundant space inside the receiving cavity and reducing the volume of the lamp frame 101.

[0048] Furthermore, there are two connecting ribs 211, and the storage part 22 is located between the two connecting ribs 211; setting the number of connecting ribs 211 to two can improve the stability of the connection between the lamp arm 2 and the profile frame 1.

[0049] Furthermore, combining Figure 8 and Figure 9 The outer frame 101 of the lamp also includes two brackets 3, which are located inside the receiving cavity, and the storage part 22 is located between the two brackets 3. The brackets 3 are formed by bending a sheet profile, wherein the sheet profile is bent at an angle that matches the profile frame 1 so that the brackets 3 can better fit the inner peripheral wall of the side wall 121.

[0050] The bracket 3 is preferably riveted to the profile frame 1 to ensure that the bracket 3 is reliably fixed to the profile frame 1. In addition, one bracket 3 is also connected and fixed to the profile frame 1 and a connecting rib 211 by fasteners (such as bolts). The number of connecting ribs 211 is set to two to improve the stability of the connection between the lamp arm 2 and the profile frame 1. Since the profile frame 1 is provided with a clearance opening 15 for the storage part 22 to pass through, the structural strength of the profile frame 1 will be affected at the clearance opening 15. By adding the bracket 3, the structural strength of the profile frame 1 can be improved, ensuring the reliability of the connection between the profile frame 1 and the lamp arm 2.

[0051] In a better way, combined with Figure 10 The base plate 132 of the L-shaped plate 13 and the support surface 1221 of the bearing part 122 have a first gap W1, the difference between the first gap W1 and the height H of the bracket 3 is between 3 mm and 5 mm. Due to the existence of the clearance opening 15, the mechanical properties of the profile frame 1 are weakest at the bending corner near the clearance opening 15, and the shear force is very large, which makes it easy to tear when severe conditions (such as typhoons, drops, vibrations, etc.) occur. Therefore, by setting the bracket 3 to cover the stress situation of the profile frame 1, the shear force at the bending corner is converted into the direct compressive force of the profile frame 1. By distributing the compressive force on the bracket 3, the support surface 1221 of the bearing part 122, and the base plate 132 of the L-shaped plate 13, and by the difference between the first gap W1 and the height H of the bracket 3, the deformation of the profile frame 1 at the bending corner is limited to between 0.15 mm and 0.25 mm, ensuring that the profile frame 1 will not be damaged at the weak bending corner.

[0052] At least one light-emitting module 102 is provided, and each light-emitting module 102 is connected to the first slot 1222 by fasteners (such as bolts). The first cover plate 103 is also connected to the first slot 1222 by fasteners, and the light-emitting module 102 cooperates with the first cover plate 103 to cover the first opening of the receiving cavity. The second cover plate 104 is connected to the second slot 1311 of the profile frame 1 by fasteners, and the second cover plate 104 covers at least a portion of the second opening of the receiving cavity; preferably, the second cover plate 104 completely covers the second opening of the receiving cavity. A power module 105 is disposed between the first cover plate 103 and the second cover plate 104, and the power module 105 is connected to either the first cover plate 103 or the second cover plate 104, and is electrically connected to the light-emitting module 102 to provide stable power to the light-emitting module 102. In addition to covering the opening of the receiving cavity, the first cover plate 103 and the second cover plate 104 also provide installation space for the power module 105, thereby further utilizing the redundant space inside the receiving cavity.

[0053] In summary, by designing the profile frame 1 of the lamp 100, the profile 10 can be bent to form the profile frame 1 after being cut to the corresponding length according to the power of the lamp 100 (i.e., the number of light-emitting modules 102). This eliminates the need to design a mold of corresponding size for each type of lamp 100, thus reducing production costs. Furthermore, it can minimize the number of components in the lamp frame 101, reduce assembly complexity, and improve the overall reliability of the profile frame 1 and the lamp 100.

[0054] Finally, it should be emphasized that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. For those skilled in the art, the present utility model can have various changes and modifications. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
