DETAILED DESCRIPTION

[0030] In order to make the objectives, technical solutions and advantages of this application clearer, this application is described in detail below with reference to the accompanying drawings and specific embodiments.

[0031] It should be noted here that in order to avoid obscuring the present application due to unnecessary details, only the structures and / or processing steps closely related to the scheme of the present application are shown in the accompanying drawings, while other details that are not closely related to the present application are omitted.

[0032] In addition, it should be noted that the terms "comprises", "includes" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or apparatus that includes a series of elements includes not only those elements, but also includes other elements not explicitly listed, or also includes elements inherent to such process, method, article or apparatus.

[0033] Refer to Figures 1 to 8 , which illustrate a preferred embodiment of a lamp 100 of the present application. Lamp 100 comprises a cover 1, a housing 2, a power cord 3, a light-emitting assembly 4, and a face ring 7. The cover 1 is positioned over the exterior of the housing 2, with the cover 1 and housing 2 forming a securing structure 10 for securing the power cord 3. The power cord 3 and light-emitting assembly 4 are fixedly and electrically connected. The light-emitting assembly 4 is positioned between the face ring 7 and the housing 2, on the side of the housing 2 facing away from the cover 1. When the light-emitting assembly 4 is secured to the housing 2, the power cord 3 is secured between the housing 2 and the cover 1 via the securing structure 10. This arrangement utilizes the inherent structure of the housing 2 and cover 1 to secure the power cord 3 in place, eliminating the need for a separate wire clamp and reducing costs. Furthermore, the power cord 3 does not require bending during installation, making threading easy and assembly simple and user-friendly, offering excellent convenience. Furthermore, the power cord 3 is securely and reliably installed, resisting external forces, meeting safety regulations for push-pull protection and eliminating the need for a lightning bolt.

[0034] The power cord 3 includes a body 31 and a clamping portion 32 disposed on the body 31. The clamping portion 32 has a larger diameter than the body 31 and is configured to connect to the fixing structure 10. The larger diameter of the clamping portion 32 improves the secure connection of the power cord 3 and prevents breakage of the body 31 of the power cord 3.

[0035] Furthermore, the power cord 3 also includes a retaining portion 33, which is disposed on the connecting portion 32 and protrudes relative to the connecting portion 32 in the circumferential direction of the power cord 3. In other words, the retaining portion 33 is disposed on the connecting portion 32, and the volume of the retaining portion 33 is larger than the volume of the connecting portion 32. This arrangement facilitates the insertion of the connecting portion 32 through the fixing structure 10 of the lamp 100, while the retaining portion 33 is retained in place.

[0036] Furthermore, the clamping portion 32 includes a first clamping portion 321 disposed above the holding portion 33 and a second clamping portion 322 disposed below the holding portion 33. The first clamping portion 321 is configured to pass through the cable hole 11 in the cover 1, and the second clamping portion 322 is configured to pass through the cable slot 21 in the housing 2. Preferably, the shape of the first clamping portion 321 is different from that of the second clamping portion 322 to distinguish the installation direction of the power cord 3.

[0037] The diameter of the end of the first clamping portion 321 close to the holding portion 33 is larger than the diameter of the end away from the holding portion 33. This arrangement allows the first clamping portion 321 to have a structure with a gradually increasing diameter from top to bottom, so that the outer surface of the first clamping portion 321 is an inclined outer surface, which facilitates the first clamping portion 321 to pass through the wire hole 11. At the same time, the hole wall of the wire hole 11 is clamped on the outer surface of the first clamping portion 321 to limit the holding portion 33.

[0038] The fixing structure 10 includes a cover body 1 and a shell body 2. The cover body 1 is provided with a wire hole 11. The shell body 2 is accommodated inside the cover body 1. The shell body 2 is provided with a wire groove 21 at a position corresponding to the wire hole 11. The wire hole 11 and the wire groove 21 are used to pass the clamping portion 32 of the power cord 3. A fixing portion 101 is formed between the shell body 2 and the cover body 1. The fixing portion 101 is configured to accommodate a fixed clamping portion 33. The upper and lower sides of the fixing portion 101 are respectively provided with a wire hole 11 and a wire groove 21, and the orthographic projection of the fixing portion 101 exceeds the orthographic projection range of the wire hole 11 and the orthographic projection range of the wire groove 21, so that the clamping portion 32 can pass through the wire groove 21 and the wire hole 11. However, the wire groove 21 and the wire hole 11 limit and fix the clamping portion 33 in the fixing portion 101. This arrangement allows the power cord 3 to be positioned and fixed by the structure of the housing 2 and the cover 1 itself, eliminating the need for additional wire pressing plates or raised mounting structures, thereby reducing the volume of the lamp 100 and lowering costs. Furthermore, the smaller second clamping portion 322 and first clamping portion 321 of the power cord 3 can respectively pass through the wire groove 21 on the housing 2 and the wire hole 11 on the cover 1, while the larger retaining portion 33 is fixed within the fixing portion 101 by the wire groove 21 and the wire hole 11, that is, by the shell walls of the housing 2 and the cover 1. This secures the power cord 3 within the fixing structure 10, preventing it from being pulled off. This ensures a secure and reliable installation of the power cord 3, meeting safety regulations for preventing push-pull damage and eliminating the need for a lightning bolt. Furthermore, the power cord 3 does not need to be bent during installation, making threading easy and assembly simple and easy, providing excellent convenience.

[0039] It should be noted that the above-mentioned orthographic projection refers to the projection of the fixing part 101, the wire groove 21 and the wire hole 11 on the plane perpendicular to the extension direction of the power cord 3 (the horizontal plane in Figure 4) from the extension direction of the power cord 3 (the vertical direction in Figure 4).

[0040] Furthermore, on a plane perpendicular to the extension direction of the power cord 3 (a horizontal plane in this embodiment), the projected area of ​​the wire hole 11 and the wire groove 21 is larger than the projected area of ​​the clamping portion 32, but smaller than the projected area of ​​the retaining portion 33. This arrangement allows the clamping portion 32 to pass smoothly through the wire hole 11 and the wire groove 21, while the retaining portion 33, due to its larger size, is constrained and fixed within the fixing portion 101.

[0041] Furthermore, the cover 1 is made of a thermally conductive material, such as aluminum or other suitable metal, non-metal, or mixed material, to facilitate heat dissipation. The cover 1 includes an outer base 12 and an outer wall 13 extending from the periphery of the outer base 12 toward the inner side of the outer base 12 and protruding away from the outer base 12. The outer base 12 and the outer wall 13 together enclose a receiving cavity. The housing 2 is housed in the receiving cavity of the cover 1.

[0042] In some embodiments, a heat dissipation contact area 14 is provided on the cover 1 at a position corresponding to the mounting opening 23 on the shell 2. The heat dissipation contact area 14 protrudes from the side of the outer wall 13 of the cover 1 away from the outer base 12 toward the shell 2, and passes through the mounting opening 23 to approach the light-emitting component 4 of the lamp 100 to actively dissipate heat for the light-emitting component 4.

[0043] Furthermore, the wire-passing hole 11 is provided on the outer side wall 13 to avoid interfering with the heat dissipation efficiency of the heat dissipation contact area 14 .

[0044] Several first recessed areas 131 are provided on the outer wall 13 near the outer base 12, and first fixing holes 15 are provided in the first recessed areas 131 and pass through the outer base 12. Preferably, the first fixing holes 15 are locking holes configured to allow fasteners 8 to pass through to fix the cover body 1, shell 2 and face ring 7 of the lamp 100.

[0045] In this embodiment, four first recessed areas 131 are provided, evenly distributed along the outer wall 13. Each first recessed area 131 is provided with a first fixing hole 15. This arrangement improves the stability of the connection of the lamp 100. It should be noted that the number of first recessed areas 131 and first fixing holes 15 can be increased or decreased as needed, and the positions of the first recessed areas 131 and first fixing holes 15 can also be adjusted as needed, as long as stable installation of the lamp 100 is achieved.

[0046] Furthermore, the outer wall 13 is provided with a plurality of second recessed areas 132, each of which is provided with a mounting spring 16. The mounting spring 16 is configured to facilitate mounting the lamp 100 as a whole in a corresponding mounting area. Preferably, two mounting springs 16 are provided, and the two mounting springs 16 are arranged opposite each other.

[0047] The housing 2 is made of insulating material and includes an inner wall 24 , which is convex toward the cover 1 to form a receiving portion for receiving the light emitting assembly 4 .

[0048] Furthermore, a mounting opening 23 is provided in the center of the inner sidewall 24, occupying more than half the area of ​​the housing 2. This arrangement allows the light-emitting assembly 4 to be housed within the housing while creating a large heat dissipation window, facilitating heat dissipation from the light-emitting assembly 4. Furthermore, the mounting opening 23 facilitates the passage of the power cord 3, resolving the difficulty of threading the power cord 3.

[0049] Furthermore, the housing 2 is provided with a fixing groove 22, which is disposed on the inner sidewall 24 and is recessed inward from the top surface of the housing 2. Optionally, the shape of the fixing groove 22 is consistent with the shape of the retaining portion 33 of the power cord 3, so as to facilitate securing the retaining portion 33 within the fixing groove 22. In this embodiment, the fixing groove 22 is a square fixing groove 22. In other embodiments, the fixing groove 22 may also have other shapes.

[0050] Furthermore, the fixing groove 22 and the cover 1 together form a fixing portion 101 , and the fixing portion 101 is used to accommodate and fix the clamping portion 33 of the power cord 3 .

[0051] In some embodiments, the wire groove 21 is arranged on the bottom wall 221 of the fixed groove 22 and passes through the bottom wall 221, and on a plane perpendicular to the extension direction of the power cord 3, the projected area of ​​the wire groove 21 on the plane is smaller than the projected area of ​​the fixed groove 22 on the plane. In other words, the wire groove 21 is arranged on the fixed groove 22, and the wire groove 21 is a structure that passes through the fixed groove 22, and the orthographic projection of the fixed groove 22 exceeds the orthographic projection range of the wire groove 21. This arrangement facilitates the passing of the clamping portion 32 of the power cord 3 through the wire groove 21, while the holding portion 33 is limited by the wire groove 21 in the fixed groove 22. At the same time, due to the presence of the cover body 1, the top of the holding portion 33 is limited and fixed, so that the holding portion 33 is accommodated and fixed in the fixed portion 101, preventing the power cord 3 from being pulled off, and meeting the safety anti-push requirements.

[0052] In some embodiments, an opening 211 is provided on the side of the wire groove 21 away from the edge of the shell 2, and the opening 211 is connected to the installation opening 23. That is, the installation opening 23 and the fixing groove 22 are connected through the wire groove 21. This arrangement facilitates the clamping portion 33 and the clamping portion 32 of the power cord 3 to enter the top of the shell 2 from the installation opening 23, and then the clamping portion 32 arranged below the clamping portion 33 enters the fixing groove 22 through the wire groove 21, while the clamping portion 32 arranged above the clamping portion 33 passes through the wire hole 11 on the cover body 1, and the circumferential area of ​​the clamping portion 33 is larger than the circumferential area of ​​the wire groove 21 and the wire hole 11, so that it is limited and fixed in the fixing portion 101 formed by the fixing groove 22 (or the shell 2) and the cover body 1.

[0053] In some embodiments, the fixing groove 22 further includes a side wall 222, which is perpendicular to the bottom wall 221. The side wall 222 is provided with a protrusion (not shown), which extends from the side wall 222 into the interior of the fixing groove 22 to abut the clamping portion 33. The provision of the protrusion further secures the clamping portion 33 within the fixing portion 101, preventing it from shaking within the fixing portion 101, thereby improving the firmness of the clamping portion 33 and meeting the safety anti-push requirements.

[0054] Furthermore, a third recessed area 25 is provided on the inner wall 24 corresponding to the first recessed area 131 of the outer wall 13, and a second fixing hole 26 is provided in the three recessed areas, which passes through the inner wall 24. The second fixing hole 26 corresponds to the first fixing hole 15 on the cover body 1 to facilitate the passage of the fastener 8, thereby realizing a fixed connection between the shell 2 and the cover body 1.

[0055] As shown in Figures 2 and 3, the light-emitting assembly 4 is housed within the housing 2 and is at least partially exposed within the mounting opening 23, corresponding to the heat dissipation contact area 14 on the cover 1, to facilitate heat dissipation. The light-emitting assembly 4 includes a circuit board, several light sources mounted on the circuit board, and supporting electronic components. In this embodiment, the light-emitting assembly 4 is a DOB light source electronic assembly, but other suitable light sources or light source assemblies may also be used, without limitation.

[0056] Furthermore, the lamp 100 may further include a heat conducting member 5, which is disposed between the light-emitting assembly 4 and the housing 2 and is at least partially exposed within the mounting opening 23 to correspond to the heat dissipation contact area 14 on the cover 1. This facilitates heat generated by the light-emitting assembly 4 to be transferred to the heat dissipation contact area 14 through the heat conducting member 5 for dissipation. The heat conducting member 5 may be made of thermally conductive silicone cloth or other suitable material.

[0057] Furthermore, in order to improve the lighting effect of the lamp 100 , a lens 6 may be provided on the side of the light emitting component 4 away from the housing 2 , and a plurality of reflective edges 61 may be provided on the side of the lens 6 facing the light emitting component 4 to improve the lighting effect of the lamp 100 .

[0058] The face ring 7 is located on the side of the light-emitting assembly 4 facing away from the housing 2 and includes an outer edge 71 and a connecting portion 72 disposed inside the outer edge 71. The connecting portion 72 extends from the surface of the outer edge 71 toward the light-emitting assembly 4. A retaining groove 73 is provided between the outer edge 71 and the connecting portion 72. The cover 1 is snapped into the retaining groove 73 to enhance the stability of the connection of the lamp 100.

[0059] Furthermore, the face ring 7 also includes an anti-fouling protrusion 74 provided on the side of the connecting portion 72 away from the outer edge portion 71. At least one of the lens 6 and the housing 2 is provided with an anti-fouling groove 62 that cooperates with the anti-fouling protrusion 74 to facilitate quick and accurate positioning during assembly.

[0060] Furthermore, third fixing holes 75 are respectively provided on the face ring 7 at positions corresponding to the first fixing holes 15 , and the fasteners 8 pass through the first fixing holes 15 , the second fixing holes 26 and the third fixing holes 75 to fix the cover body 1 , the shell 2 and the face ring 7 together.

[0061] When assembling the lamp 100 of the present application, the power cord 3 is first fixedly connected to the light-emitting component 4 and electrically connected together, and then the power cord 3 is passed through the installation opening 23 of the shell 2. After the light-emitting component 4 and the heat-conducting member 5 are installed in the receiving cavity of the shell 2, the second clamping portion 322 of the power cord 3 is inserted into the wire groove 21 through the installation opening 23 on the shell 2, and the clamping portion 33 is installed in the fixing groove 22. Due to the large size of the clamping portion 33, it cannot pass through the wire groove 21 and the wire hole 11, and is thus fixed in the fixing groove 22 and limited by the fixing portion 101 formed by the fixing groove 22 and the cover body 1. The first clamping portion 321 arranged above the clamping portion 33 can smoothly pass through the wire hole 11 on the cover body 1 and connect to the external power supply. After the lens 6 is installed, it is positioned and connected to the face ring 7 through the anti-fouling groove 62 and anti-fouling protrusion 74. The fastener 8 passes through the first fixing hole 15, the second fixing hole 26, and the third fixing hole 75 to securely connect the cover 1, the shell 2, and the face ring 7. At this point, the clamping portion 33 of the power cord 3 is clamped between the shell 2 and the cover 1, eliminating the need for an additional wire pressing structure. At the same time, the power cord 3 is easy to insert and remove, meeting the safety regulations for push-pull resistance testing.

[0062] In summary, the fixing structure 10 of the present application has a simple structure. A fixing portion 101 is formed between the shell 2 and the cover 1 to accommodate the clamping portion 33 for fixing the power cord 3. A wire groove 21 and a wire hole 11 are respectively provided on the shell 2 and the cover 1. At the same time, the wire hole 11 and the wire groove 21 are respectively provided on the upper and lower sides of the fixing portion 101, and the orthographic projection of the fixing portion 101 exceeds the orthographic projection range of the wire hole 11 and the wire groove 21 respectively, so that the clamping portion 33 of the power cord 3 is limited and fixed in the fixing portion 101 through the wire hole 11 and the wire groove 21, so that there is no need to design too many additional structures. The power cord 3 is limited and fixed with the help of the structure of the shell 2 and the cover 1 itself, and the power cord 3 does not need to be bent during installation, and the wiring is easy. The assembly is simple and easy to operate, and it has good convenience. At the same time, the power cord 3 is installed firmly and securely, and is not easily pulled off by external force, meeting the safety regulations for anti-push and anti-pull requirements, and eliminating the need for a lightning mark.
