Description

Technical Field

[0001] This invention relates to the field of lighting fixtures, and in particular to an LED downlight and its mounting and dismounting method. Background Technology

[0002] A downlight is a type of light fixture installed on a ceiling or wall. For example... Figure 1 The downlight shown has a fixing structure including two clips 21 and a U-shaped bracket 22. The clips 21 are located on the back of the downlight. When installing the downlight, the U-shaped bracket 22 is first placed on the ceiling. The downlight is then installed on the ceiling by engaging the clips 21 with the U-shaped bracket 22. The installation process is quick and convenient.

[0003] However, because the clips 21 are engaged with the U-shaped bracket 22, it is impossible to directly apply force to remove the downlight from the U-shaped bracket 22. The downlight is equipped with a dedicated pull ring 23, and the clips 21 have threaded holes that match the pull ring 23. When performing the disassembly operation, the pull ring 23 is inserted into the downlight, and the pull ring 23 is rotated to screw it into the threaded hole, so that the pull ring 23 is threadedly connected to the clips 21. This creates a fulcrum for applying force on the outside of the downlight. By applying pulling force to the pull ring 23, the two clips 21 can be pulled apart from the U-shaped bracket 22, and the downlight can then be removed.

[0004] The above disassembly process has the following problems: 1. When disassembling the downlight, a pull ring 23 needs to be temporarily installed; 2. The disassembly method of the pull ring 23 and the buckle 21 does not restrict the operator's disassembly actions. If the operator does not follow the established disassembly procedure, the downlight may accidentally fall during the disassembly process, causing damage to the downlight or injuring the operator, resulting in a safety accident. For example, if the operator performs the disassembly operation with one hand, using the pull ring 23 to pull one side of the buckle 21 to separate it from the Z-shaped bracket 22, and then releases their hand to pull the other side of the pull ring 23, since one side of the buckle 21 has already disengaged from the Z-shaped bracket 22, and only the other side of the buckle 21 is hooked onto the Z-shaped bracket 22, the connection between the downlight and the Z-shaped bracket 22 cannot be effectively maintained by only one side of the buckle 21. The downlight may accidentally fall when the operator releases their hand. Summary of the Invention

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide an LED downlight and its installation and removal method, so that the downlight is more securely fixed and retains the characteristics of quick installation and convenient disassembly.

[0006] The objective of this invention is achieved through the following technical solution: An LED downlight includes: a lamp body, a ceiling bracket, and a quick-release assembly; The lamp body includes a housing and a light source plate, a lens, and a driver disposed on the housing, wherein the driver is electrically connected to the light source plate; The ceiling bracket is installed on the suspended ceiling; The quick-release assembly includes a pull rod and two opposing latches. Each latch includes a base, a return spring, and a latch tongue. The latch tongue is movably disposed in the inner cavity of the base and has a stop surface and an inclined surface. When the inclined surface abuts against the ceiling bracket, the latch retracts into the inner cavity of the base; When the inclined surface leaves the ceiling bracket, the return spring drives the latch to extend out of the inner cavity of the base so that the stop surface locks the ceiling bracket. The lever passes through the latch, and the lever is used to drag the latch away from the ceiling bracket.

[0007] In one embodiment, the side of the housing has a through hole, the latch has a connecting hole, the connecting hole is aligned with the through hole, and the pull rod passes through the through hole and is threadedly connected to the connecting hole.

[0008] In one embodiment, the housing is provided with a plug for sealing the through hole.

[0009] In one embodiment, the lever includes a sleeve and a pin. Two latches are respectively inserted through the sleeve and the pin. A torsion spring is provided on the sleeve and the pin within the latches, and a blocking ring is provided on the sleeve and the pin outside the latches. A stepped docking hole is provided at the end of the sleeve, with a limiting area and a movable area. A step is provided at the boundary between the limiting area and the movable area. The pin has a docking portion and a locking protrusion. The locking protrusion is located on the outer wall of the docking portion, which is located within the stepped docking hole. The locking protrusion is located in the movable area. The limiting area has a slide for the locking protrusion to pass through, and the slide communicates with the movable area. The torsion spring drives the sleeve and the pin to rotate, causing the locking protrusion to be misaligned with the slide, allowing the step to block the locking protrusion. After the locking protrusion aligns with the slide, it can move away from the movable area along the slide.

[0010] In one embodiment, the blocking ring is located in the gap between the latch and the actuator.

[0011] In one embodiment, both the sleeve and the pin are elongated rod-shaped structures, with the end of the sleeve away from the latch and the end of the pin away from the latch extending to the outside of the housing.

[0012] In one embodiment, the inner wall of the base is provided with a plurality of anti-deviation protrusions, which are fitted against the outer wall of the latch.

[0013] In one embodiment, the latch further includes a stud that passes through the base and is threadedly connected to the latch tongue.

[0014] In one embodiment, the ceiling bracket is provided with an anti-disengagement buckle, and the housing is provided with an anti-fall rope that matches the anti-disengagement buckle.

[0015] A method for installing and removing LED downlights includes the following steps: Step 1: After installing the ceiling bracket in the ceiling, connect the wires to the light body; Step 2: Adjust the position of the light body so that the ceiling bracket is between the two clips, then push the light body so that the latches lock onto the ceiling bracket. Installation is complete. Step 3: Hold the sleeve and the pin with both hands respectively, and apply torque to make the sleeve and the pin rotate relative to each other; Step 4: After the locking protrusion is aligned with the slide, apply a pulling force while dragging the sleeve and the pin to move them away from each other and open the latch, thus releasing the connection between the buckle and the ceiling bracket. Step 5: Disconnect the wires connected to the lamp body to complete the disassembly operation.

[0016] In summary, the clips work together with the ceiling bracket to fix the light body to the ceiling. The clips and the ceiling bracket have rigid contact, so they will not fall off when subjected to accidental pulling force. The clips are rigid components and will not deform due to long-term use, thus avoiding the problem of the light fixture becoming loose. At the same time, the clips and the pull rod work together to easily remove the light body from the ceiling bracket, allowing the downlight to retain the characteristics of quick installation and convenient disassembly.

[0023] Please see Figure 2 The present invention provides an LED downlight 10, which includes: a lamp body 100, a ceiling bracket 200 and a quick-install assembly.

[0024] Please see Figure 2 and Figure 6 The lamp body 100 includes a housing 110 and a light source plate 120, a lens 130, and a driver 140 disposed on the housing 110. The driver 140 is electrically connected to the light source plate 120. Please see Figure 2 and Figure 3 The ceiling bracket 200 is installed on the ceiling; Please see Figure 2 and Figure 4 The quick-release assembly includes a lever 300 and two opposing latches 400. Each latch 400 includes a base 410, a return spring 420, and a latch 430. The base 410 has a hollow structure, and the latch 430 is movably disposed within the inner cavity of the base 410. The return spring 420 is located between the inner wall of the base 410 and the latch 430, and provides elastic force to drive the latch 430 toward the opening position of the base 410.

[0025] Please see Figure 2 and Figure 4 The latch 430 is provided with a stop surface 431 and an inclined surface 432. During the process of connecting the lamp body 100 with the ceiling bracket 200, when the latch 430 contacts the ceiling bracket 200 and the inclined surface 432 abuts against the ceiling bracket 200, the latch 430 retracts into the inner cavity of the base 410; when the inclined surface 432 leaves the ceiling bracket 200, the return spring 420 drives the latch 430 to extend out of the inner cavity of the base 410, and the stop surface 431 latches the ceiling bracket 200, thereby connecting the lamp body 100 and the ceiling bracket 200 together. The weight of the lamp body 100 acts on the stop surface 431 and the ceiling bracket 200. Both the latch 430 and the ceiling bracket 200 are rigid components, so the lamp body 100 is not easy to fall off when subjected to accidental pulling force, and the latch 430 will not deform, which can avoid the problem of the downlight becoming loose.

[0026] The lever 300 passes through the latch 430. The latch 430 can be driven to retract into the base 410 by the lever 300, thereby separating the latch 430 from the ceiling bracket 200, thus achieving quick disassembly.

[0027] When the main body 100 of the lamp is suspended, the inclined surface 432 contacts the ceiling bracket 200, and the latch 430 retracts into the base 410 under the guidance of the inclined surface 432. The latch 430 then pops out again to hook the ceiling bracket 200, and at this time, the stop surface 431 contacts the ceiling bracket 200. The stop surface 431 is a non-inclined contact surface, so directly applying a pulling force to drag the main body 100 will not separate it from the ceiling bracket 200. While ensuring that the main body 100 will not fall off or loosen under accidental pulling force, it also means that the main body 100 cannot be disassembled using the installation procedure. When the downlight malfunctions or needs to be replaced with another style of downlight due to interior decoration, the original main body 100 needs to be disassembled. To prevent the downlight from accidentally falling due to disassembly errors, the lever 300 is also improved as follows: Please see Figure 5 and Figure 6 The lever 300 includes a sleeve 310 and a pin 320. Both the sleeve 310 and the pin 320 are mounted on the LED downlight 10. The sleeve 310 and the pin 320 are respectively provided with two latches 430. A torsion spring 434 is provided on the sleeve 310 and the pin 320 at a position inside the latches 430. A blocking ring 330 is provided on the sleeve 310 and the pin 320 at a position outside the latches 430. The blocking ring 330 is located in the gap between the latches 430 and the driver 140.

[0028] Please see Figure 6 and Figure 7 The sleeve 310 has a stepped docking hole 311 at its end. The stepped docking hole 311 has a limiting area 31 and a movable area 32. The diameter of the movable area 32 is larger than the diameter of the limiting area 31. A step 33 is provided at the boundary between the limiting area 31 and the movable area 32. Please see Figure 6 and Figure 7 The pin 320 is provided with a docking part 321 and a locking protrusion 322. The locking protrusion 322 is located on the outer wall of the docking part 321. The docking part 321 is located in the stepped docking hole 311. During normal use and disassembly of the LED downlight 10, the docking part 321 is always located in the stepped docking hole 311.

[0029] The locking protrusion 322 is located in the active area 32. The limiting area 31 is provided with a slide 34 for the locking protrusion 322 to pass through. The slide 34 is connected to the active area 32. The slide 34 limits the locking protrusion 322, so that the locking protrusion 322 can slide along the extension direction of the slide 34, but cannot rotate relative to the slide 34.

[0030] The torsion spring 434 is used to drive the sleeve 310 and the pin 320 to rotate so that the locking protrusion 322 is misaligned with the slide 34, and the step 33 blocks the locking protrusion 322. When performing the disassembly operation, the sleeve 310 and the pin 320 need to be turned so that the locking protrusion 322 is aligned with the slide 34, so that the locking protrusion 322 can move away from the active area 32 along the slide 34, and then push the latch 430 through the blocking ring 330, so that the latch 430 leaves the ceiling bracket 200 to complete the unlocking operation.

[0031] Both the sleeve 310 and the pin 320 are slender rod-shaped structures. The end of the sleeve 310 away from the latch 430 and the end of the pin 320 away from the latch 430 both extend to the outside of the housing 110, forming a gripping fulcrum on the outside of the housing 110.

[0032] This application also provides a method for assembling and disassembling an LED downlight based on Embodiment 2, comprising the following steps: Step 1: After installing the ceiling bracket 200 into the ceiling, connect the wires to the lamp body 100; Preferably, the ceiling bracket 200 is equipped with an anti-disengagement buckle 210, and the housing 110 is equipped with a fall arrestor rope that matches the anti-disengagement buckle 210. By tying the fall arrestor rope to the anti-disengagement buckle 210, the lamp body 100 can be initially connected to the ceiling bracket 200, allowing the operator to perform wire connection operations without having to hold the lamp body 100 for the entire process.

[0033] Step 2: Adjust the position of the light body 100 so that the ceiling bracket 200 is between the two clips 400, then push the light body 100 so that the latch 430 locks the ceiling bracket 200 in place. Installation is complete. When adjusting the position, the ceiling bracket 200 is positioned between the two clips 400. When the main body 100 of the ceiling light approaches the ceiling bracket 200, the inclined surface 432 on the latch 430 first contacts the ceiling bracket 200. At this time, the applied pushing force will generate a horizontal component force at the contact point between the inclined surface 432 and the ceiling bracket 200, causing the latch 430 to retract into the inner cavity of the base 410. After the inclined surface 432 passes the ceiling bracket 200, the latch 430 will pop out again, and the stop surface 431 on the latch 430 will lock the ceiling bracket 200, completing the installation operation.

[0034] Step 3: Hold the sleeve 310 and the pin 320 with both hands respectively, and apply torque to make the sleeve 310 and the pin 320 rotate relative to each other; Before being disturbed by external forces, the torque provided by the torsion spring 434 causes the slide rail 34 to be misaligned with the locking protrusion 322. Due to the dimensional difference between the moving area 32 and the limiting area 31, the locking protrusion 322 is confined within the limiting area 31, thus preventing the sleeve 310 and the pin 320 from moving away from each other. Rotating the sleeve 310 and the pin 320 adjusts the relative positions of the slide rail 34 and the locking protrusion 322, aligning the locking protrusion 322 with the slide rail 34, allowing the sleeve 310 and the pin 320 to slide relative to each other. It is important to emphasize that the rotation range of the sleeve 310 and the pin 320 is limited by the torsion spring 434. Both the sleeve 310 and the pin 320 must be rotated separately to ensure alignment between the locking protrusion 322 and the slide rail 34. Rotating either the sleeve 310 or the pin 320 alone will result in the locking protrusion 322 failing to align with the slide rail 34 due to the limited rotation range. Therefore, this process requires the operator to use both hands.

[0035] Step 4: After the locking protrusion 322 is aligned with the slide rail 34, apply a pulling force and simultaneously drag the sleeve 310 and the pin 320 to move them away from each other to open the latch 430 and release the connection between the buckle 400 and the ceiling bracket 200. When the sleeve 310 and the pin 320 are driven away from each other, the blocking ring 330 on the sleeve 310 and the pin 320 will push the latch 430. The process of applying force is actually to drive the latch 430 back into the base 410, thereby separating the latch 430 from the ceiling bracket 200 and achieving quick disassembly.

[0036] Step 5: Disconnect the wires connected to the lamp body 100 to complete the disassembly operation.

[0037] It should be noted that steps 1 to 2 are the installation process of the LED downlight 10, and steps 3 to 5 are the disassembly process of the LED downlight 10. During the above installation and disassembly process, the locking protrusion 322 never leaves the stepped docking hole 311, that is, the sleeve 310 and the pin 320 will not detach from the housing 110. Furthermore, the retaining ring 330 on the sleeve 310 and the pin 320 is located in the gap between the latch 430 and the driver 140. Therefore, during the installation of the downlight, the process of the latch 430 retracting into the base 410 under the guidance of the inclined surface 432 is not blocked by the retaining ring 330. In other words, the retaining ring 330 only abuts against the latch 430 during the disassembly process and acts as a fulcrum to apply external pulling force to the latch 430 to make it detach from the ceiling bracket 200.

[0038] Furthermore, when no external force is applied, the latch 430 and the blocking ring 330 work together to drive the sleeve 310 and the pin 320 to move closer together. After the locking protrusion 322 enters the active area 32, the torsion spring 434 drives the locking protrusion 322 to be misaligned with the slide rail 34, thereby locking the sleeve 310 and the pin 320 together. That is, the sleeve 310 and the pin 320 can automatically reset after the external force is removed. On the other hand, before the unlocking action in step 3 is performed, the external force can only drive the sleeve 310 and the pin 320 to rotate relative to each other, but cannot drive the sleeve 310 and the pin 320 to translate, making the connection between the sleeve 310 and the pin 320 and the lamp body 100 more secure. When a foreign object scrapes against the lever 300, it will not cause the lamp body 100 to fall off accidentally.

[0039] It is important to emphasize that both the sleeve 310 and the pin 320 will automatically reset under the action of the torsion spring 434 after no external force is applied or after the external force is removed. This means that if the operator does not hold the sleeve 310 and the pin 320 with both hands, the lock between the sleeve 310 and the pin 320 cannot be released smoothly. Before performing the unlocking action in step 3, the sleeve 310 and the pin 320 can only rotate relative to each other and cannot move horizontally. Thus, the operator cannot drag either the sleeve 310 or the pin 320 horizontally, and therefore cannot separate one of the latches 430 from the ceiling bracket 200. The operator can only drag the sleeve 310 and the pin 320 away from each other after holding the sleeve 310 and the pin 320 with both hands and performing the unlocking action in step 3. This ensures that the operator performs the disassembly of the downlight with both hands. The sleeve 310 and the pin 320 work together to restrict the disassembly process and ensure that the operator performs the disassembly action with both hands, thereby preventing the downlight from falling accidentally during the disassembly process.

[0040] In summary, the LED downlight 10 has the following beneficial effects: 1. The clip 400 and the ceiling bracket 200 work together to fix the lamp body 100 to the ceiling. The latch 430 and the ceiling bracket 200 are in rigid contact, so it will not fall off when subjected to accidental pulling force. The latch 430 is a rigid component and will not deform due to long-term use, which can avoid the problem of the lamp loosening. At the same time, the latch 430 and the pull rod can easily remove the lamp body 100 from the ceiling bracket 200, so that the downlight can retain the characteristics of quick installation and convenient disassembly.

[0041] 2. Only after applying torque to align the locking protrusion 322 with the slide rail 34 can the lock between the sleeve 310 and the pin 320 be released. Then, the latch 430 is driven to disengage from the ceiling bracket 200 by the blocking ring 330. Before the lock is released, the sleeve 310 and the pin 320 can only rotate relative to each other. The sleeve 310 and the pin 320 cannot be moved without an unlocking action. The operator must hold the sleeve 310 and the pin 320 with both hands to perform the unlocking action before the latch 430 can be driven to disengage from the ceiling bracket 200. The structure of the sleeve 310 and the pin 320 restricts the operator's disassembly action and ensures the safety of the downlight disassembly process. 3. The sleeve 310 and the pin 320 are directly fixed to the lamp body 100. After the unlocking action is performed, they can be used to disassemble the downlight without the need for temporary assembly of parts or additional storage space, thus avoiding the inability to disassemble the downlight normally due to the loss of parts. After the external force is removed, the sleeve 310 and the pin 320 can automatically reset with the cooperation of the latch 430 and the torsion spring 434 without the need for additional operation, making the process of disassembling and reinstalling the downlight more convenient.

[0042] In one embodiment, the inner wall of the base 410 is provided with multiple anti-deviation protrusions 411. The anti-deviation protrusions 411 fit against the outer wall of the latch 430, reducing the contact area between the base 410 and the latch 430, reducing the resistance during the movement of the latch 430, and preventing the latch 430 from getting stuck. Preferably, the buckle 400 also includes a stud 440, which passes through the base 410 and is threadedly connected to the latch 430. The stud 440 restricts the movement distance of the latch 430. At the same time, the part of the stud 440 that contacts the base 410 is smooth, so the stud 440 can also restrict the direction of movement of the latch 430, preventing the latch 430 from deviating from its movement trajectory and getting stuck, ensuring that the latch 430 can move smoothly on the base 410 during the installation and removal of the downlight.

[0043] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this invention patent should be determined by the appended claims.
