Description

Technical Field

[0001] This application relates to the field of tri-proof lights, and more particularly to a modular LED tri-proof light with built-in driver. Background Technology

[0002] As a lighting device suitable for humid, dusty, or corrosive environments, the structural reliability and sealing performance of LED rugged lights are crucial. Traditional rugged lights typically require complex ribs or slots on the inner wall of the light-emitting tube to secure the light-emitting components. This design necessitates injection molding of the light-emitting tube using specific molds, limiting the choice of materials (e.g., glass cannot be used) and manufacturing processes, increasing costs, and affecting light uniformity. Regarding sealing, traditional structures have many exposed components, resulting in long sealing interfaces and numerous potential leakage points. Even with waterproof gaskets, they are prone to failure under structural deformation or installation stress. Therefore, there is an urgent need for a rugged light structure that is simplified, reliably fixed, and fundamentally reduces leakage paths. Summary of the Invention

[0003] The technical problem this application aims to solve is that traditional rugged lights typically require complex rib or slot structures designed on the inner wall of the light-emitting tube to fix the light-emitting components inside. This design necessitates injection molding of the light-emitting tube using specific molds, limiting the choice of materials (e.g., glass cannot be used) and manufacturing processes, increasing costs and affecting light emission uniformity. Regarding sealing, traditional structures have many exposed components, resulting in long sealing interfaces and numerous potential leakage points. Even with waterproof gaskets, they are prone to failure under structural deformation or installation stress. To address these shortcomings of the prior art, this application provides a modular LED rugged light with a built-in driver.

[0004] To solve the above-mentioned technical problems, the technical solution adopted in this application is: A modular, built-in driver-based tri-proof LED light is constructed, comprising a light-emitting tube, a light-emitting component disposed within the light-emitting tube, and end cap assemblies disposed at both ends of the light-emitting tube. The light-emitting component has inner plugs at both ends, and the end cap assemblies are connected to outer plugs. An expansion ring is disposed between the outer plug and the inner plug. The outer plug and the inner plug are connected by a locking mechanism. When locked, the two are driven to move closer together, compressing the expansion ring and causing it to expand radially, thereby fixing and supporting the light-emitting component on the inner wall of the light-emitting tube.

[0005] Preferably, the expansion ring is a circular elastic body with a first inner diameter and a second inner diameter at its two ends. The first inner diameter transitions into a first boss on the outer plug, and the second inner diameter transitions into a second boss on the inner plug. The light-emitting tube is a straight tube with a circular cross-section and no positioning ribs on its inner wall.

[0006] Preferably, the inner wall of the second inner diameter is an inclined edge that slopes toward the center of the expansion ring.

[0007] Preferably, the locking mechanism is a locking screw that passes through the outer plug and screws into the inner plug.

[0008] Preferably, the inner plug is provided with an arc-shaped rib, which is in close contact with the inner wall of the profile of the light-emitting component to prevent rotation.

[0009] Preferably, the light-emitting component includes a profile, a first lamp panel and a second lamp panel disposed on different sides of the profile, and a built-in drive and control board. The control board is provided with a DIP switch for independently adjusting the color temperature and on / off state of the first lamp panel and the second lamp panel.

[0010] Preferably, the end cap assembly includes an end cap and a waterproof rubber ring. The waterproof rubber ring has multiple barbed ribs with a barbed cross-section. When the waterproof rubber ring is compressed, the barbed ribs and the inner wall of the end of the light-emitting tube are pressurized to form a unique waterproof and dustproof sealing interface.

[0011] Preferably, the end cap is rotatably engaged with the ear groove on the outer plug via an ear on it. The ear is provided with an outward angled buckle and a concave point, and the ear groove is provided with an inward angled buckle and a protruding point that cooperate with it.

[0012] Preferably, the waterproof rubber ring has at least two barbed ribs, and its outer diameter is larger than the inner diameter of the light-emitting tube.

[0013] The beneficial effects of this application are: simplified structure and strong material versatility: the light-emitting component is fixed from the inside by the expansion of the rubber ring, which eliminates the complex positioning structure of the inner wall of the light-emitting tube, so that the light-emitting tube can use a general-purpose tube with a simple circular cross-section (such as glass tube, drawn plastic tube, etc.), which significantly reduces mold cost and material selection restrictions.

[0014] The core sealing path is singular and highly efficient: Because the expansion-type structure houses most of the lamp body components, the traditional multi-layered sealing is simplified to a single critical sealing interface—the gap between the light-emitting tube and the end cap. By incorporating a waterproof rubber ring with barbed ribs at this location, and utilizing the ribs' large deformation and resilience, an ultimate seal is achieved over this single gap, significantly improving waterproof and dustproof performance.

[0015] Reliable fixation without stress damage: The expansion ring provides a uniform radial tightening force, avoiding the concentrated stress caused by screws directly tightening onto the light output tube, preventing tube cracking, and making the fixation safer and more reliable.

[0016] Assembly process optimization: This design enables modular assembly, allowing the light-emitting components to be pre-installed independently, and then the whole assembly is placed into the light-emitting tube and quickly locked with the end cap to complete the final seal, which greatly improves production efficiency and maintenance convenience.

Detailed Implementation

[0018] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, a clear and complete description will be provided below in conjunction with the technical solutions in the embodiments of this application. Obviously, the described embodiments are some embodiments of this application, but not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this application.

[0019] A modular, built-in driver LED tri-proof light according to a preferred embodiment of this application; such as Figure 1 As shown, the light-emitting component 2 includes an outer plug 4 located on both sides of the light-emitting component 2 and connected to it via an expansion ring 3. The light-emitting component 2 and the outer plug 4 are integrally fitted with a light-emitting tube 1. The light-emitting tube 1 is a straight tube with a circular cross-section, a smooth inner wall without any positioning ribs, and its inner diameter is clearance-fitted with the outer diameter of the expansion ring 3 after expansion. The outer plug 4 and the light-emitting component 2 are connected and locked together by a locking screw 4. An end cap assembly 7 is externally connected to the outer plug 4, and the end cap assembly 7 is equipped with a waterproof connector 9. This end cap assembly 7 is a key sealing component for achieving the three-proof performance of the lamp.

[0020] Specifically, such as Figure 2 and Figure 3 As shown, the light-emitting component 2 includes a profile 20 with a semi-circular internal structure and a hollowed-out section extending to both sides to facilitate heat dissipation and wiring. Two sets of first slots 201 are provided on the profile 20, forming a first clamping area 202 between them. The first lamp panel 22 is placed within the first clamping area, with its light-emitting surface facing away from the profile. Two sets of second slots 203 are also provided on the profile, forming a second clamping area 204 between them. The second lamp panel 23 is placed within the second clamping area, with its light-emitting surface facing away from the profile. This allows the light-emitting surfaces of the first and second lamp panels to be positioned in different directions when they emit light, improving the lighting effect. Simultaneously, a built-in driver 21 electrically connected to the first and second lamp panels is provided within the profile 20. Inner plugs 24 are provided on both sides of the profile, sealing the openings on the left and right sides. One set of inner plugs 24 houses a control board 25, which includes a first DIP switch 250 and a second DIP switch 251. The first DIP switch 250 controls the color temperature of the first lamp panel 22 and the second lamp panel 23, while the second DIP switch 251 controls the on / off state of the first and second lamp panels. This allows the two sets of lamp panels to be independently controlled for color temperature and on / off state via the two DIP switches. Power cords are connected to the profile and electrically to the control board. The control board is electrically connected to the built-in driver and controls the operation of the first and second lamp panels. Figure 13 As shown in this application, the built-in driver 21 is electrically connected to the terminal block, and then connected to the control board 25. The two sets of lamp boards are connected in parallel to the control board and controlled independently by the control board.

[0021] Furthermore, to address the issue of traditional tri-proof lights requiring complex ribs to be designed on the inner wall of the light-emitting tube to fix the light-emitting components, such as... Figures 4-5 As shown, this application employs an innovative expansion and tightening fixing scheme. The inner plug 24 has a second protrusion 240 facing the expansion ring 3, and the outer plug 4 has a first protrusion 50 facing the expansion ring 3. The expansion ring 3 is respectively fitted onto the first and second protrusions. When the outer plug 4 and the inner plug 24 are brought closer together by the locking screw, the expansion ring 3 is axially compressed, forcing it to undergo radial elastic expansion deformation, thereby tightly pressing against the inner wall of the light-emitting tube 1, reliably fixing and supporting the entire light-emitting component 2 inside the light-emitting tube 1. This fixing method allows the light-emitting tube 1 to use a universal round tube with a smooth inner wall, significantly broadening the range of material choices and reducing costs. The first protrusion 50 and the second protrusion 240 can be set with different radii. The expansion ring 3 is a circular structure, and correspondingly, it also has a first inner diameter 30 and a second inner diameter 31 of different sizes. The different inner diameters facilitate the differentiation of the installation direction. The second inner diameter 31 is provided with an inclined edge 32, which is inclined toward the middle of the expansion ring. This increases the friction as the expansion ring is fitted into the second boss 240, resulting in a better fixing effect. The first boss and the first inner diameter can also use the same inclined edge, which will not be described in detail here. The expansion ring can be made of silicone or rubber, which has good elasticity and aging resistance.

[0022] Furthermore, such as Figures 2-3 and Figures 6-9 As shown, to prevent the inner plug from rotating after being inserted into the profile, an arc-shaped rib 242 is provided on the inner plug. The arc-shaped rib corresponds to the inner wall 205 of the profile. When the arc-shaped rib is inserted into the profile, it is tightly attached to the inner wall and cannot rotate. Multiple sets of clips 241 are provided on the side of the inner plug 24 facing the profile 20. The control board 25 is connected to the inner plug through the clips, facilitating the installation and removal of the control board. Both the inner plug 24 and the outer plug 4 have DIP switch holes 54 corresponding to the first DIP switch 250 and the second DIP switch 251. The DIP switches pass through the DIP switch holes to expose the DIP switches on the outer plug for easy operation. Simultaneously, the inner plug and the outer plug have wire holes 56 corresponding to the power cord and screw holes 55 for inserting locking screws 4.

[0023] Furthermore, such as Figure 8 and Figures 10-12As shown, the end cap assembly 7 is the core component for achieving the three-proof performance of this application. The end cap assembly 7 includes an end cap 70 and a waterproof rubber ring 71. The waterproof rubber ring 71 is the only waterproof and dustproof component in this embodiment, and its key feature is that it has multiple protruding ribs 710 with a cross-section in the shape of barbs. The end cap 70 is provided with a rubber ring groove 700 to accommodate the waterproof rubber ring 71. The end cap 70 is also provided with two sets of latches 702, and the outer plug 4 is provided with latch grooves 51 corresponding to the latches. When the end cap is connected to the outer plug, the latches are placed in the latch grooves, and the latches 702 are provided with an outwardly angled buckle 703, and the latch groove is provided with an inwardly angled buckle 52 corresponding to the outwardly angled buckle. The outwardly angled buckle 703 is provided with a concave point 704, and a protruding point 53 is provided in the latch groove. During the rotation of the end cap, the beveled surfaces of the outward and inward fasteners engage to tighten the end cap, while the waterproof rubber ring 71 is axially compressed. The barbed rib 710 on the ring creates a strong interference fit with the inner wall of the light-emitting tube 1, forming an extremely reliable sealing interface. When the protrusion 53 slides into the recess 704, a clear clicking sound indicates that the end cap is locked and properly sealed. A first circular hole 701 is provided on one side of the end cap 70, through which the waterproof connector 9 passes and is connected and locked to the nut 8.

[0024] The tri-proof light of this application follows the logic of fixing first and then sealing during assembly. The specific steps are as follows: First, perform modular pre-assembly of the light-emitting component 2: insert the first lamp plate 22 into the first slot 201 of the profile 20, and insert the second lamp plate 23 into the second slot 203. Fix the control plate 25 to one set of inner plugs 24 using clips 241, and then insert the two sets of inner plugs 24 into the profile 20 from both sides, so that the arc rib 242 is tightly attached to the inner wall 205 of the profile, thus completing the independent pre-assembly of the light-emitting component.

[0025] Next, the fixing steps are performed: the pre-assembled light-emitting component 2 is placed into the light-emitting tube 1. The expansion ring 3 is fitted onto the second boss 240 of the inner plug 24 with its second inner diameter 31 side. Then, the outer plug 4 is aligned with the inner plug 24, so that the DIP switch hole 54 and the wire hole 56 are aligned, and the locking screw 4 is screwed through the outer plug 4 into the screw hole 55 of the inner plug 24. During the locking process, the outer plug 4 and the inner plug 24 move closer together, squeezing the expansion ring 3, causing it to expand radially and press tightly against the inner wall of the light-emitting tube 1, thereby firmly fixing the light-emitting component 2 in the center of the light-emitting tube.

[0026] Finally, perform the sealing step: insert the waterproof rubber ring 71 into the rubber ring groove 700 of the end cap 70. Then align the retainer 702 of the end cap 70 with the retainer groove 51 of the outer plug 4, insert and rotate the end cap 70. During rotation, the oblique outer buckle 703 engages with the oblique inner buckle 52, pulling the end cap 70 towards the outer plug 4, while simultaneously compressing the waterproof rubber ring 71 forcefully, causing its barbed rib 710 to tightly seal against the inner wall of the end of the light outlet tube 1. When the protrusion 53 snaps into the recess 704 with a crisp sound, it indicates that the seal is in place. Finally, pass the waterproof connector 9 through the first round hole 701 of the end cap 70 and tighten it with the nut 8.

[0027] During assembly, electrical connections are made between the built-in driver 21, control board 25, wiring terminals, and lamp board.

Furthermore, based on the teachings of this application, these features and embodiments can be modified to suit specific circumstances and materials without departing from the spirit and scope of this application.
