[0022] like Figures 1 to 7 As shown, a rear cover structure for a lamp includes a rear cover body 1. The rear cover body 1 includes a cover plate 11 and a surrounding plate 12. At least two spaced mounting structures 2 are provided on the inner side of the rear cover body 1. The mounting structures 2 are located on the inner sidewall of the cover plate 11 or the surrounding plate 12. The mounting structure 2 includes a support member 25 and a first fastener 24 located on the upper side of the support member 25. A gap is left between the support member 25 and the first fastener 24. The support member 25 is used to support the power board 10, and the first fastener 24 is used to lock the edge of the power board 10 and restrict the power board 10 from moving away from the support member 25.

[0023] In this embodiment, when installing the power board 10, simply press the power board 10 onto the support member 25 so that the snap-fit ​​member engages with the edge of the power board 10, and the power board 10 can be installed on the inner side of the back cover body 1. This structural form eliminates the need for drilling holes or screwing into the power board 10 during production, and only requires simple positioning during installation. From production to assembly, this facilitates the formation of the back cover structure and improves production efficiency.

[0024] There are two configuration options for installation structure 2, as follows: Example 1: The mounting structure 2 includes a first mounting component 21, which includes a connecting plate 23, a support member 25, and a first fastener 24. The connecting plate 23 is disposed on the cover plate 11 and has a gap between it and the surrounding plate 12. The support member 25 and the first fastener 24 are both disposed on the side of the connecting plate 23 facing the center of the cover plate 11, and the first fastener 24 is located directly above the support member 25.

[0025] Example 2: The mounting structure 2 includes a second mounting component 22, which includes a connecting plate 23, a support member 25, and a first fastener 24. The connecting plate 23 is disposed on the cover plate 11 and has a gap between it and the surrounding plate 12. The first fastener 24 is disposed on the side of the connecting plate 23 facing the center of the cover plate 11, and the support member 25 is located on the side of the connecting plate 23.

[0026] In the above embodiment 1, the supporting member 25 and the first fastener 24 are integrated into a whole by the connecting plate 23, which reduces some steps in the production and installation process of the lamp and speeds up the production and installation process, thereby improving the production efficiency of the back cover structure and the lamp.

[0027] In the above embodiment 2, since it is necessary to integrate the various components inside the lamp, it is inevitable that some components cannot be installed inside the lamp in a regular shape. The power board 10 is no exception. This means that the appropriate support position on the power box may not be the appropriate locking position. Therefore, it is necessary to set the support 25 and the first fastener 24 in a staggered manner so that the mounting structure 2 is more suitable for the installation of the irregularly shaped power board 10.

[0028] refer to Figure 1 The figure discloses a specific embodiment of a rear cover structure. Three mounting structures 2 are provided on the inner side of the rear cover structure, including two first mounting components 21 and one second mounting component 22. Three support members 25 are evenly spaced around the center of the circular cover plate 11, forming a stable triangular support structure. In the second mounting component 22, a notch is formed at the position of the power board 10 corresponding to the support member 25. If the first fastener 24 is placed at this location, it may be too close to the center of the cover plate 11, and its protruding structure may obstruct the installation of other structures in the rear cover structure. Therefore, the first fastener 24 in the second mounting component 22 is placed beside the support member 25. The first fastener 24 can both secure the power board 10 and be close to the surrounding plate 12.

[0029] It is worth noting that the support member 25 in this embodiment can support the power board 10 when it is installed, and the support member 25 is located on the upper side of the power board 10 during the use of the lamp.

[0030] In this embodiment, the fastener has an inclined surface 241, which gradually slopes towards the center of the cover plate 11 in a direction from away from to near the cover plate 11. During installation, the edge of the power board 10 abuts against the inclined surface 241 and is then pressed down (i.e., pressed towards the cover plate 11). Due to the compression, the fastener will move appropriately towards the surrounding plate 12. Therefore, a gap is left between the connecting plate 23 and the surrounding plate 12, which also provides space for the displacement of the fastener after being pressed by the power board 10, avoiding collision and friction between the installation structure 2 and the surrounding plate 12. After the power board 10 is pressed down until it passes over the fastener, the fastener resets, thus restricting the power board 10 from moving away from the cover plate 11, completing the fastening installation.

[0031] In some specific embodiments, reference is made to Figure 1 The cover plate 11 is provided with two spaced mounting posts 4, which are used to install the heat dissipation structure 20 of the lamps. The mounting posts 4 are located near the enclosure plate 12.

[0032] In this embodiment, since the rear cover structure is provided with three mounting structures 2 and two mounting posts 4, all of which are located close to the enclosure 12, it is necessary to stagger the positions of the three mounting structures 2 and the two mounting posts 4 to avoid affecting the installation.

[0033] In some specific embodiments, reference is made to Figure 1 The enclosure 12 is provided with a wire passage groove 3. The wire passage groove 3 is close to the cover plate 11 and its extension direction is perpendicular to the cover plate 11. When the power board 10 is installed, the wire passage groove 3 is connected to the space between the power board 10 and the cover plate 11.

[0034] The rear cover structure has a dedicated cable tray 3 to centrally arrange the wires, which facilitates more orderly wiring and improves safety. The support component 25 also creates a space between the power board 10 and the cover plate 11 after the power board 10 is installed, allowing the wires to extend through the cable tray 3 into the space between the cable tray 3 and the power board 10 and the cover plate 11 and connect to the power board 10.

[0035] This embodiment also proposes a lamp, see reference. Figures 4 to 7 This includes the back cover structure of the aforementioned lamps.

[0036] In some specific embodiments, reference is made to Figure 4 , Figure 6 and Figure 7The luminaire also includes a heat dissipation structure 20 and a light source assembly disposed within the heat dissipation structure 20. The heat dissipation structure 20 is mounted on the rear cover body 1. The light source assembly includes a COB light source 30, a light source pressure plate 40, and an optical device group 80 arranged in sequence. The light source pressure plate 40 is used to press the COB light source 30. The COB light source 30 is provided with two oppositely arranged wiring portions 301. The light source pressure plate 40 is provided with two oppositely arranged wiring holes 402. The two wiring holes 402 and the two wiring portions 301 correspond one-to-one. Both sides of the light source pressure plate 40 are provided with extension mounting plates 401. One end of the extension mounting plate 401 is connected to the edge of the light source pressure plate 40, and the other end extends away from the light source pressure plate 40. The end of the extension mounting plate 401 away from the light source pressure plate 40 is provided with a pressure plate mounting hole 4011.

[0037] In this embodiment, the COB light source 30 is generally rectangular, with two wiring portions 301 at its two opposite corners. An extension mounting plate 401 is provided, and the pressure plate mounting hole 4011 is located at the end of the extension mounting plate 401 away from the light source pressure plate 40. This allows the screws for mounting the light source pressure plate 40 to be positioned away from the wiring portions 301, thereby increasing the creepage distance, reducing the risk of short circuits, and improving the safety of the luminaire.

[0038] In some specific embodiments, reference is made to Figure 4 and Figure 5 The lamp also includes a heat dissipation structure 20 and an anti-glare plate 50. The rear cover body 1, the heat dissipation structure 20 and the anti-glare plate 50 are arranged in sequence. The anti-glare plate 50 is provided with a module limiting structure 60 on the side facing the heat dissipation structure 20. A networking module 70 is installed on the module limiting structure 60. The module limiting structure 60 includes at least two second fasteners 601 and at least one limiting post 602. The networking module 70 includes a module plate. The module plate is provided with at least one limiting hole 701. The limiting post 602 passes through the limiting hole 701. The two second fasteners 601 are located on both sides of the module plate and fasten the module plate to restrict the module plate from moving away from the anti-glare plate 50. The limiting hole 701 and / or the second fasteners 601 can restrict the rotation of the module plate.

[0039] In the existing technology, the networking module 70 is installed on the anti-glare plate 50 by hot melting. However, this installation method is not very applicable to networking modules 70 of different specifications, which is not conducive to improving assembly efficiency.

[0040] The different specifications of the networking module 70 mainly lie in the difference in length. In this embodiment, the second fastener 601 is set on both sides of the networking module 70. Therefore, networking modules 70 of different lengths can be installed on the module limiting structure 60 as long as they do not protrude from the installation range of the lamp. Then, the limiting post 602 restricts the movement and rotation of the networking module 70 along its length direction, so that the networking module 70 can be stably installed on the anti-glare plate 50.

[0041] In some specific embodiments, reference is made to Figure 4 The lighting fixture also includes a power board 10, which has at least two straight edges 101, and the two straight edges 101 correspond to the positions of the two mounting structures 2.

[0042] The snap-fit ​​component in mounting structure 2 engages with the straight edge 101 of the power board 10, which increases the engagement area between the power board 10 and the snap-fit ​​component, thereby improving the stability of the engagement and the stability of the installation position.

[0043] In some specific embodiments, reference is made to Figure 4 The lamp also includes a heat dissipation structure 20 and a light source assembly disposed inside the heat dissipation structure 20. The heat dissipation structure 20 is disposed on the rear cover body 1 and has a wire hole 201 for the wires connecting the light source assembly and the power board 10 to pass through.

[0044] In this embodiment, the wire through hole 201 and the wire through groove 3 are positioned correspondingly. The wires connecting the light source assembly and the power board 10 pass through the wire through hole 201 and the wire through groove 3, which is beneficial for the orderly arrangement of wires inside the lamp and improves safety.

[0045] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
