[0039] like Figures 1 to 3 , Figure 5 and Figure 7As shown, the LED lamp provided in the embodiment of this application includes a lamp housing assembly 10, a diffuser plate 20, and an LED light source assembly 30. The lamp housing assembly 10 includes a frame 11 and a back plate 12. The frame 11 forms a light outlet, and the back plate 12 covers the end of the frame 11 away from the light outlet to form a receiving space 14. The diffuser plate 20 is connected to the frame 11 and located at the light outlet. The LED light source assembly 30 is installed in the receiving space 14 and emits light to illuminate the diffuser plate 20. Furthermore, the frame 11 includes an outer frame 110 and an inner frame 112. The outer frame 110 is fitted and fixed to the inner frame 112. The outer frame 110 is a seamless, one-piece component. The back plate 12 is connected to the outer frame 110 and covers the inner frame 112. The LED light source assembly 30 is disposed within the inner frame 112, and the diffuser plate 20 is connected to the end of the inner frame 112 away from the back plate 12.

[0040] When using the LED lamp provided in the embodiments of this application for illumination, the LED light source assembly 30 emits light to illuminate the diffuser plate 20, and then the light is emitted through the diffuser plate 20 for illumination. The lamp housing assembly 10 of the LED lamp includes a frame 11 and a back plate 12. The back plate 12 covers the end of the frame 11 away from the light outlet to form a receiving space 14. The LED light source assembly 30 is assembled in the receiving space 14. The back plate 12 can block light leakage from one side of the back plate 12. Furthermore, the frame 11 includes an outer frame 110 and an inner frame 112. The outer frame 110 is fitted and fixed to the inner frame 112. Since the outer frame 110 is a seamless one-piece component, that is, the outer frame 110 fits around the inner frame 112 so that light cannot be emitted from any circumferential position of the frame 11. The light can only be emitted through the diffuser plate 20 located at the light outlet for illumination, eliminating lateral light leakage. Compared to the LED lamps in related technologies where there are seams between the two ends of adjacent frame plates causing light leakage, the LED light source assembly 30 in the LED lamp provided in this application can only emit light through the diffuser plate 20 located at the light outlet for illumination. The seamless, one-piece outer frame 110 can eliminate lateral light leakage, thereby improving light efficiency.

[0041] In some embodiments of this application, the outer frame 110 includes multiple frame plates 111, each of which is manufactured separately and then joined end-to-end. Each frame plate 111 is made of aluminum alloy, and the two mating ends of adjacent frame plates 111 are welded together. Thus, the entire outer frame 110 is ultimately formed as a seamless, one-piece component. The outer frame 110 fits onto the inner frame 112, thereby preventing light leakage at any circumferential position of the entire frame 11, thus eliminating the problem of lateral light leakage from the LED light. Furthermore, the aluminum alloy outer frame 110 is lightweight and strong, contributing to the overall weight reduction of the LED light.

[0042] In some other embodiments of this application, the outer frame 110 is a one-piece molded component. Through a casting process, the outer frame 110 is integrally cast from aluminum alloy, resulting in high processing efficiency. The one-piece molded outer frame 110 is seamless, and since it fits onto the inner frame 112, no light leakage occurs at any circumferential position of the entire frame 11, thus eliminating the problem of lateral light leakage from the LED light. Furthermore, the aluminum alloy outer frame 110 is lightweight yet strong, contributing to the overall lightweight design of the LED light.

[0043] In other embodiments of this application, the outer frame 110 may also be made of plastic material and integrally injection molded, which is not limited here.

[0044] In the LED light provided in the embodiments of this application, the overall outline of the frame 11 is rectangular.

[0045] like Figure 6 and Figure 8 As shown, the inner wall of the outer frame 110 has a circumferential protrusion 113. When the outer frame 110 is fitted onto the inner frame 112, the end of the inner frame 112 away from the diffuser plate 20 abuts against the side of the protrusion 113 facing the light outlet. This restricts and determines the assembly position of the inner frame 112 inserted into the outer frame 110, achieving the first positioning of the inner frame 112 within the outer frame 110. Furthermore, the back plate 12 covers the side of the protrusion 113 opposite to the inner frame 112. Specifically, as... Figure 1 , Figure 3 , Figures 5 to 8 As shown, the back plate 12 is locked to the protruding structure 113 by bolts 40, which facilitates connection and assembly and improves assembly efficiency. Furthermore, as... Figure 6 and Figure 8 As shown, the outer frame 110 has a slot 114 on its end wall away from the back plate 12, and the inner frame 112 has a hook 115 on its outer wall away from the back plate 12. The hook 115 engages with the slot 114, thus achieving a second positioning of the outer frame 110 on the inner frame 112. The first and second positioning work together to restrict the positioning, ensuring that the outer frame 110 stably fits and restricts the inner frame 112.

[0046] In the LED lights of the embodiments of this application, such as Figure 6 and Figure 8 As shown, the inner wall of the inner frame 112 at the end away from the back plate 12 is provided with a circumferential first protrusion 116, specifically, as shown in the figure. Figure 3 As shown, the inner frame 112 includes multiple independent frame strips 119, each corresponding to a multiple frame plate 111. The frame strips 119 are connected end-to-end but not fixed. When the outer frame 110 is fitted onto the inner frame 112, the outer frame 110 fixes the multiple frame strips 119 end-to-end. Correspondingly, as... Figure 4 , Figure 6 and Figure 8As shown, the diffuser plate 20 has a circumferential slot 21 on its circumferential sidewall. When assembling the diffuser plate 20 with the inner frame 112, the first protrusion 116 of each frame strip 119 is inserted into the circumferential slot 21. At this point, the multiple frame strips 119 are joined end-to-end but not fixed. A clamp can be used to hold the multiple frame strips 119 in place to maintain their relative position to the diffuser plate 20. Then, the outer frame 110 is fitted onto the inner frame 112, and the clamp is removed. The outer frame 110 then frames the multiple frame strips 119, forming an inner frame 112 joined end-to-end. Screws are then passed through the protrusion structure 113 and screwed in to lock each frame strip 119, thus simultaneously assembling and fixing the outer frame 110, inner frame 112, and diffuser plate 20. Next, the back plate 12 is placed on the side of the protrusion structure 113 facing away from the inner frame 112, and bolts 40 are used to lock the back plate 12 to the protrusion structure 113.

[0047] To facilitate the assembly of the LED light source assembly 30, such as Figure 6 and Figure 8 As shown, the inner wall of the inner frame 112 is also provided with a second circumferential protrusion 117, which is located between the protrusion structure 113 and the first protrusion 116. Figure 3 , Figures 5 to 8 As shown, the LED light source assembly 30 includes an LED light strip 31 and a light guide structure 32. The LED light strip 31 is attached to the inner wall of the inner frame 112 and located between the protruding structure 113 and the second protrusion 117. The circumferential edge region of the light guide structure 32 is sandwiched between the protruding structure 113 and the second protrusion 117. Furthermore, the LED chip 311 of the LED light strip 31 is directly opposite to the corresponding part of the circumferential sidewall of the light guide structure 32. The light emitted by the LED light strip 31 is incident on the light guide structure 32 for propagation. The light guide structure 32 propagates the light to the diffuser plate 20 and emits light for illumination. Specifically, when the first protrusion 116 of each frame strip 119 is inserted into the circumferential slot 21 and each frame strip 119 is temporarily fixed with a clamp, the LED light strip 31 is attached to the inner wall of the corresponding frame strip 119, and then the light guide structure 32 is placed on the second protrusion 117. Next, the outer frame 110 is fitted onto the inner frame 112 and the clamps are removed. Thus, multiple frame strips 119 are enclosed by the outer frame 110, forming an inner frame 112 with its ends connected. Screws are then passed through the protruding structure 113 and screwed in to lock each frame strip 119. The protruding structure 113 and the second protrusion 117 clamp and fix the circumferential edge area of ​​the light guide structure 32. Then, the back plate 12 is placed on the side of the protruding structure 113 facing away from the inner frame 112, and bolts 40 are used to lock the back plate 12 to the protruding structure 113. The bolts 40 pass through the protruding structure 113 and abut against the light guide structure 32, further securing the light guide structure 32 and preventing it from shaking or shifting.

[0048] In the LED lights of the embodiments of this application, such as Figure 3 , Figures 5 to 8 As shown, the light guide structure 32 includes a light guide plate 321, a reflective layer 322, and a buffer member 323. Along the direction from the diffuser plate 20 to the back plate 12, the light guide plate 321, reflective layer 322, and buffer member 323 are stacked sequentially. Furthermore, the LED chip 311 of the LED strip 31 faces the circumferential sidewall of the light guide plate 321. The light emitted by the LED strip 31 is incident on the light guide plate 321 and propagates. Part of the light is directly propagated by the light guide plate 321 to illuminate the diffuser plate 20, while another part is propagated by the light guide plate 321 to the reflective layer 322. The reflective layer 322 reflects the light back into the light guide plate, and then propagates it again by the light guide plate 321 to illuminate the diffuser plate 20. During the process of the LED strip 31 emitting light, heat is generated. To quickly dissipate this heat, such as… Figure 6 and Figure 8 As shown, the outer wall of the inner frame 112 is provided with multiple spaced heat dissipation fins 118, which abut against the inner wall of the outer frame 110. The heat generated by the LED light strip 31 is quickly transferred to the inner frame 112, and then transferred to the outer frame 110 with the assistance of the heat dissipation fins 118, thereby dissipating the heat into the outside air, achieving heat dissipation and cooling of the LED light strip 31, and preventing it from overheating.

[0049] Preferably, in some embodiments, the outer wall of the frame 119 in which the LED light strip 31 is mounted is provided with a plurality of spaced heat dissipation fins 118.

[0050] And, as Figure 6 and Figure 8As shown, bolt 40 passes through protrusion 113 and abuts against buffer member 323. Bolt 40 and second protrusion 117 clamp and fix light guide structure 32. Light guide plate 321 is a fragile and easily broken structural component, such as glass plate or acrylic plate. The buffer member 323 buffers the abutment force of bolt 40, effectively protecting light guide plate 321 and reducing the possibility of light guide plate 321 being crushed or cracked. Specifically, the buffer component 323 includes a buffer layer 3231 and multiple buffer strips 3232. Each buffer strip 3232 corresponds to one of the multiple frame strips 119. The buffer layer 3231 is laid and bonded to the side of the reflective layer 322 facing away from the light guide plate 321. The multiple buffer strips 3232 surround the buffer layer 3231 end-to-end and are located at the edge area of ​​the reflective layer 322. The bolt 40 passes through the protrusion structure 113 and abuts against the buffer strip 3232, thereby clamping and fixing the reflective layer 322 and the light guide plate 321 together with the second protrusion 117. In the embodiments of this application, the buffer layer 3231 can be a foam layer or other flexible layer, covering and protecting the reflective layer 322 from scratches by foreign objects. The buffer strips 3232 can be flexible strips such as silicone strips or rubber strips. The buffer strips 3232 have elastic deformation capability, undergoing elastic deformation when abutted by the bolt 40 to buffer the compressive force of the bolt 40 on the light guide plate 321 and protect the light guide plate 321.

[0051] like Figures 1 to 3 , Figure 5 and Figure 7 As shown, the LED light also includes a driver 50, which is mounted on the side of the back plate 12 away from the receiving space 14. The driver 50 supplies power to the LED light source assembly 30. Specifically, the driver 50 includes a dust cover 51 and an electrical component 52. The electrical component 52 is mounted on the side of the back plate 12 away from the receiving space 14, and the dust cover 51 is used to protect the electrical component 52.

[0052] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
