Description

Technical Field

[0001] The utility model relates to the technical field of lamps, in particular to a downlight that can be quickly disassembled. Background Art

[0002] A downlight is a kind of lighting fixture that can be embedded in the ceiling and emits light downward. It is favored by the public because it can maintain the overall unity and perfection of building decoration.

[0003] The existing downlights are divided into integral type and split type. In order to facilitate the later maintenance and upkeep of the downlights, the downlights often adopt a split structure, that is, the drive module and the light source module of the downlight can be disassembled and separated. When the drive module or the light source module is damaged, only the damaged part needs to be replaced, reducing the maintenance cost and also reducing the waste of resources.

[0004] However, in the existing split downlights, the detachable connection between the drive module and the light source module is achieved by means of threads or buckles, and the drive module and the light source module also need to be powered through electric wires. Therefore, after the structures of the drive module and the light source module are detached, the electric wires connecting the two also need to be disconnected, and the operation process is very troublesome, time-consuming, and has low safety. Summary of the Utility Model

[0005] The utility model aims to solve at least one of the technical problems existing in the prior art. For this purpose, the utility model provides a downlight that can be quickly disassembled.

[0006] The solution for the utility model to solve its technical problems is as follows:

[0007] A downlight that can be quickly disassembled, comprising:

[0008] An installation shell, the installation shell is provided with an installation cavity with a downward opening, and the upper wall surface of the installation shell is provided with a first installation hole, and the first installation hole communicates with the installation cavity;

[0009] A light source module, which is arranged in the installation cavity and is slidably connected to the inner wall surface of the installation cavity. The light source module is provided with a socket, and the socket protrudes upward;

[0010] A drive module, which is snap-connected to the installation shell. The drive module is provided with a pin extending downward. The pin passes through the first installation hole and is cooperatively connected with the socket. The drive module is electrically connected to the light source module through the pin.

[0011] The utility model has at least the following beneficial effects: during the disassembly process, after unlocking between the driving module and the mounting shell, applying an upward force to the driving module can make the driving module be pulled out upward, so that the driving module is separated from the mounting shell, and the pins of the driving module are disengaged from the socket of the light source module. Since the power is cut off between the light source module and the driving module after the driving module is pulled out upward from the mounting shell, there is no need to disconnect the electric wire separately, which can greatly improve the disassembly efficiency. Moreover, the safety is higher, and the risk of electric shock can be reduced; during the installation process, aligning the pins of the driving module with the socket of the light source module and inserting the pins into the socket can achieve the conductive connection between the driving module and the light source module without additional wiring operation, with high installation efficiency and high safety.

[0012] As a further improvement of the above technical solution, the mounting shell is provided with a mounting surface, the mounting surface is arranged in the mounting cavity, the light source module is arranged below the mounting surface, the mounting surface is provided with a second mounting hole and a through hole, the socket penetrates through the second mounting hole, the upper wall surface of the mounting shell is provided with a pressing hole, the pressing hole communicates with the mounting cavity, and the light source module covers the lower side of the through hole; the quickly detachable downlight further includes:

[0013] A button assembly, including an elastic member, a button and a push rod. The two ends of the elastic member are respectively connected to the mounting surface and the button, the push rod is connected to the button and extends downward, the push rod penetrates through the through hole, the button fits with the pressing hole and can enter and exit the pressing hole.

[0014] After the driving module is removed from above the mounting shell, the button can be exposed above the mounting shell. Pressing the button downward, the push rod can move downward with the button and abut against the upper surface of the light source module. When the push rod continues to move downward with the button, the push rod pushes the light source module downward, so that the light source module is disengaged from the mounting cavity from below the mounting shell, thus making it easy to remove the light source module from the mounting shell, which is more conducive to the maintenance and replacement of the light source module.

[0015] As a further improvement of the above technical solution, the quickly detachable downlight further includes:

[0016] A heat conducting sheet, the lower surface of the heat conducting sheet is connected to the upper surface of the light source module, and the heat conducting sheet covers the lower side of the through hole.

[0017] When the button is pressed, the push rod contacts the heat-conducting sheet, causing the heat-conducting sheet and the light source module to be pushed downward together. During the disassembly process of the light source module, the heat-conducting sheet remains connected to the light source module. When the light source module and the mounting shell are reassembled later, the heat dissipation ability is not lost. Moreover, since the push rod is not in direct contact with the light source module, the heat-conducting sheet can protect the light source module, increase the force-bearing area of the light source module, and avoid damage to the light source module.

[0018] As a further improvement of the above technical solution, a limiting groove with a downward opening is provided on the upper wall surface of the installation cavity. The limiting groove is arranged on the outer periphery of the pressing hole and communicates with the pressing hole. The button assembly further includes a limiting boss, and the limiting boss is arranged on the outer periphery of the button and fits with the limiting groove.

[0019] When the button is in a relaxed state, the button moves upward under the elastic action of the elastic member. The limiting boss enters the limiting groove and abuts against the upper wall surface of the limiting groove, thereby restricting the button from continuing to move upward under the action of the elastic member, thus avoiding interference of the button with the driving module located above the mounting shell and making the overall structure of the quickly detachable downlight more compact and reasonable.

[0020] As a further improvement of the above technical solution, a first hook protruding upward is provided on the side wall surface of the mounting shell, and a second hook protruding downward is provided on the side wall surface of the driving module. The first hook and the second hook are snap-connected. Through the snap connection between the first hook and the second hook, the connection between the mounting shell and the driving module is realized.

[0021] As a further improvement of the above technical solution, there are two first hooks and two second hooks respectively, and they are arranged in one-to-one correspondence. The hook part of the first hook protrudes toward the middle of the mounting shell, and the hook part of the second hook protrudes toward the outside of the driving module. Two pressing blocks are further provided on the outer side wall surface of the driving module, and the two pressing blocks are arranged in one-to-one correspondence with the two second hooks; when the first hook and the second hook are snap-connected, the pressing blocks are located above the first hook; when the two pressing blocks are pressed toward each other, the hook part of the second hook moves toward the center of the driving module, and the hook part of the second hook is separated from the hook part of the first hook.

[0022] When the two pressing blocks are pressed toward each other, the hook parts of the two second hooks move toward each other, so that the hook part of the second hook is separated from the hook part of the first hook. At this time, when the driving module is pulled upward, the separation of the driving module from the mounting shell can be realized, and the entire disassembly process is simple and fast.

[0023] As a further improvement of the above technical solution, rib strips are provided on the outer side wall surface of the driving module, the rib strips extend in the up and down direction, a clamping groove is provided on the inner side wall surface of the installation cavity, the clamping groove is open upward, and the rib strips are clamped in the clamping groove. The rib strips can be inserted into the clamping groove from above downward to align the driving module with the installation shell, achieving the function of anti-misassembly. Moreover, after the driving module and the installation shell are installed, under the limiting action of the clamping groove and the rib strips, the driving module cannot rotate relative to the installation shell, so as to ensure the stability of the connection between the driving module and the installation shell.

[0024] As a further improvement of the above technical solution, the quickly detachable downlight further includes a sealing ring, the sealing ring is provided on the inner peripheral wall surface of the installation cavity and is connected to the outer peripheral wall surface of the light source module. The setting of the sealing ring can improve the waterproof and fireproof performance of the quickly detachable downlight, and the safety is higher.

[0025] As a further improvement of the above technical solution, a connecting plate is provided at the lower end of the installation shell, the connecting plate protrudes outward, and a clamping block is provided on the outer side wall surface of the connecting plate. The quickly detachable downlight further includes:

[0026] A face cover, which is provided with a connecting groove opening upward, the connecting plate is clamped in the connecting groove and is slidably connected to the groove wall of the connecting groove. The lower groove wall of the connecting groove abuts against the lower end surface of the light source module. A bayonet is provided on the upper wall surface of the connecting groove, the bayonet is correspondingly arranged with the clamping block, and the face cover is further provided with a light-transmitting hole, and the light-transmitting hole penetrates through the upper and lower ends of the face cover and communicates with the installation cavity.

[0027] The face cover can provide an upward supporting force for the light source module, thereby further avoiding the situation that the light source module automatically falls out of the installation cavity, and the use process is safer; when the face cover needs to be removed, rotate the face cover by a certain angle so that the bayonet of the face cover is aligned with the clamping block of the installation shell, and then the face cover can be smoothly removed downward, and the disassembly and assembly process is very convenient and fast.

[0028] As a further improvement of the above technical solution, the quickly detachable downlight further includes:

[0029] A waterproof ring, which is provided in the connecting groove and is connected to the upper surface of the connecting plate.

[0030] The setting of the waterproof ring can further avoid the situation that water enters the installation cavity, improve the waterproof performance of the quickly detachable downlight, and thus extend the service life of the quickly detachable downlight. Description of the Drawings

[0046] Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, other embodiments obtained by those skilled in the art without creative efforts all fall within the scope of protection of the present utility model. Each technical feature in the present utility model can be combined interactively on the premise of not conflicting with each other.

[0047] Referring to Figures 1 to 9 , an embodiment of the present utility model provides a downlight that can be quickly disassembled, which can achieve the quick disassembly between the light source module 200 and the drive module 300, reduce the time consumed in the disassembly and assembly process, and has high safety during the disassembly process, which is more conducive to on-site construction.

[0048] Referring to Figure 1 and Figure 2, in this embodiment, the quickly detachable downlight includes an installation shell 100, a light source module 200, and a driving module 300. Among them, the installation shell 100 is hollow to form an installation cavity, the installation cavity is arranged to open downward, and a first installation hole 120 is provided on the upper wall surface of the installation shell 100, and the first installation hole 120 communicates with the installation cavity.

[0049] The light source module 200 is used for emitting light. It is arranged inside the installation cavity, and the outer wall surface of the light source module 200 is slidably connected to the inner wall surface of the installation cavity. The light source module 200 is locked with the inner wall surface of the installation cavity through friction. When a downward force is applied to the light source module 200, the light source module 200 can be disengaged from the lower opening of the installation cavity.

[0050] The driving module 300 is snap-connected to the installation shell 100. When the locking between the driving module 300 and the installation shell 100 is released, an upward force is applied to the driving module 300, and the driving module 300 can be pulled out upward and separated from the installation shell 100.

[0051] It should be noted that referring to Figure 7 , the light source module 200 of this embodiment is provided with a socket 210, and the socket 210 protrudes upward. Referring to Figure 5 , the driving module 300 is provided with a pin 310, and the pin 310 extends downward. When the light source module 200 is installed in the installation cavity and the driving module 300 is installed above the installation shell 100, the pin 310 passes through the first installation hole 120 and is cooperatively connected with the socket 210 of the light source module 200 in the installation cavity. Through the coupling between the socket 210 and the pin 310, the connection stability between the installation shell 100, the light source module 200, and the driving module 300 can be further improved. Moreover, the driving module 300 and the light source module 200 can be electrically connected through the connection between the pin 310 and the socket 210, and the driving module 300 can control the turning on or off of the light source module 200.

[0052] It can be understood that since the power is cut off between the light source module 200 and the driving module 300 after the driving module 300 is pulled out upward from the installation shell 100, there is no need to disconnect the electric wire separately, which can greatly improve the disassembly efficiency. Moreover, the safety is higher, and the risk of electric shock can be reduced.

[0053] In some embodiments, due to the narrow space of the installation cavity, it is difficult to pull out the light source module 200 downward by hand in the installation cavity. If necessary, a rod-shaped tool such as a screwdriver is used to pry out the light source module 200, but this may damage the light source module 200.

[0054] To solve the above problems and further improve the convenience of the quickly detachable downlight during the disassembly process, in this embodiment, the quickly detachable downlight further includes a button 410 assembly, which provides a downward force to the light source module 200.

[0055] Specifically, referring to Figure 6 , in this embodiment, the mounting shell 100 is provided with a mounting surface 110, the mounting surface 110 is located in the mounting cavity, the light source module 200 is arranged on the lower side of the mounting surface 110, a second mounting hole is provided on the mounting surface 110, and the second mounting hole is correspondingly arranged with the first mounting hole 120 on the upper wall surface of the mounting shell 100. When the light source module 200 is installed in the mounting cavity, the socket 210 of the light source module 200 passes through the second mounting hole to facilitate plugging with the pin 310. A through hole 111 is also provided on the mounting surface 110, and the through hole 111 penetrates the upper and lower surfaces of the mounting surface 110, and the light source module 200 covers the lower side of the through hole 111.

[0056] Referring to Figure 9 , the button assembly 400 includes an elastic member 430, a button 410, and a push rod 420. The upper end of the elastic member 430 is connected to the button 410, and the lower end is connected to the upper surface of the mounting surface 110. The push rod 420 is connected to the lower surface of the button 410 and extends downward. The button 410 fits with the pressing hole 160 and can enter and exit the pressing hole 160, and the push rod 420 passes through the through hole 111.

[0057] It can be understood that the button 410 can move in the up and down directions under the limiting action of the pressing hole 160. After removing the driving module 300 from above the mounting shell 100, the button 410 can be exposed above the mounting shell 100. Press the button 410 downward, and the push rod 420 can move downward with the button 410 and abut against the upper surface of the light source module 200. When the push rod 420 continues to move downward with the button 410, the push rod 420 pushes the light source module 200 downward, so that the light source module 200 is disengaged from the mounting cavity from below the mounting shell 100. After releasing the button 410, the button 410 can be reset under the elastic action of the elastic member 430 for the next operation.

[0058] In this embodiment, when the button 410 is not subjected to pressure and moves downward, the lower end of the push rod 420 is located in the through hole 111 and does not protrude downward from the lower surface of the mounting surface 110. Such a setting can make the light source module 200 fit with the mounting surface 110, which is more conducive to the heat dissipation of the light source module 200 and can ensure the reliability of the connection between the pin 310 and the socket 210.

[0059] It can be understood that the elastic member 430 can be a helical spring, a rubber spring, a leaf spring, etc. In this embodiment, the elastic member 430 is a helical spring, and the helical spring is sleeved outside the push rod 420. When a downward pressure is applied to the button 410, the helical spring is compressed. When the button 410 is released, the helical spring resumes. It can be understood that such a setting can enable the helical spring to be compressed along the extension direction of the push rod 420, avoid the situation of the helical spring being bent, and improve the service life of the elasticity.

[0060] In some embodiments, there are multiple push rods 420. Correspondingly, there are also multiple through holes 111. When the button 410 is pressed, the push rods 420 can simultaneously apply a driving force to the light source module 200, and the force received by the light source module 200 is relatively uniform, so that the light source module 200 can be smoothly pushed out of the installation cavity, avoiding the situation that the light source module 200 is skewed and stuck in the installation cavity.

[0061] In some embodiments, there are also multiple helical springs. The multiple helical springs are arranged in one-to-one correspondence with the push rods 420, which can enable the button 410 to move up and down smoothly, and the pressing action is more smooth.

[0062] In this embodiment, there are three push rods 420, through holes 111, and helical springs respectively. The three push rods 420 are evenly arranged circumferentially around the center of the button 410.

[0063] In some embodiments, the quickly detachable downlight further includes a heat conducting sheet 700. Refer to Figure 2 、 Figure 4 and Figure 7 , the lower surface of the heat conducting sheet 700 is connected to the upper surface of the light source module 200, and the heat conducting sheet 700 covers the lower side of the through hole 111. It can be understood that the heat conducting sheet 700 can play a role in heat conduction, enabling the light source module 200 to dissipate heat well, so as to extend the service life of the light source module 200.

[0064] It can be understood that when the button 410 is pressed, the push rod 420 contacts the heat conducting sheet 700, causing the heat conducting sheet 700 and the light source module 200 to be pushed downward together. During the disassembly process of the light source module 200, the heat conducting sheet 700 remains connected to the light source module 200, so that when the light source module 200 and the installation shell 100 are reassembled later, the heat dissipation ability is not lost.

[0065] In addition, since the push rod 420 and the light source module 200 are not in direct contact, the heat conducting sheet 700 can play a role in protecting the light source module 200, increasing the force-bearing area of the light source module 200, and avoiding the situation that the light source module 200 is damaged by the push rod 420.

[0066] In some embodiments, a limiting groove is provided on the upper wall surface of the installation cavity. The limiting groove is arranged on the outer periphery of the pressing hole 160 and is communicated with the pressing hole 160. The button assembly 400 further includes a limiting boss 440. The limiting boss 440 is arranged on the outer periphery of the button 410 and is fitted with the limiting groove.

[0067] When the button 410 is in a relaxed state, the button 410 moves upward under the elastic action of the elastic member 430. The limiting boss 440 enters the limiting groove and abuts against the upper wall surface of the limiting groove, thereby restricting the button 410 from continuing to move upward under the action of the elastic member 430, and avoiding interference of the button 410 with the driving module 300 located above the installation shell 100, making the overall structure of the quickly detachable downlight more compact and reasonable.

[0068] In some embodiments, a downward pressing mark is provided on the upper surface of the button 410. The mark can be in Chinese characters, English characters, etc., and is not specifically limited herein. When the driving module 300 is removed from above the installation shell 100, the mark is exposed, which can guide the operator to press the button 410, so that the light source module 200 can be disengaged from the installation cavity.

[0069] In some embodiments, a first hook 130 is provided on the side wall surface of the installation shell 100. The first hook 130 extends upward. A second hook 320 is provided on the side wall surface of the driving module 300. The second hook 320 extends downward. The first hook 130 is engaged with the second hook 320, thereby realizing the engagement between the installation shell 100 and the driving module 300.

[0070] Refer to Figure 5 and Figure 6 In this embodiment, two first hooks 130 and two second hooks 320 are provided, and the two first hooks 130 and the two second hooks 320 are arranged in one-to-one correspondence. It can be understood that both the first hook 130 and the second hook 320 have hook parts. Among them, the hook parts of the two first hooks 130 protrude toward the middle of the installation shell 100, while the hook parts of the two second hooks 320 protrude toward the outside of the driving module 300. The engagement between the first hook 130 and the second hook 320 is essentially the engagement between the hook part of the first hook 130 and the hook part of the second hook 320.

[0071] In this embodiment, two pressing blocks 330 are further provided on the outer side wall surface of the driving module 300. The two pressing blocks 330 are arranged in one-to-one correspondence with the two second hooks 320. When the first hook 130 is engaged with the second hook 320, the pressing blocks 330 are located above the first hook 130.

[0072] When pressing the two pressing blocks 330 towards each other, the hook parts of the two second hooks 320 move towards each other, that is, move towards the center of the driving module 300, so that the hook parts of the second hooks 320 are separated from the hook parts of the first hooks 130. At this time, pulling the driving module 300 upwards can realize the separation of the driving module 300 from the mounting shell 100, and the whole disassembly process is simple and fast.

[0073] In this embodiment, the upper wall surface of the hook part of the first hook 130 is inclined downward towards the center of the mounting shell 100, and the lower wall surface of the hook part of the second hook 320 is inclined downward towards the center of the driving module 300.

[0074] When assembling the driving module 300 and the mounting shell 100, without the pressing block 330, directly insert the driving module 300 downward above the mounting shell 100. When the first hook 130 and the second hook 320 come into contact with each other, the hook part of the second hook 320 will move towards the center of the driving module 300 under the pushing of the upper wall surface of the hook part of the first hook 130, and the assembly operation is simpler and faster.

[0075] Refer to Figure 5 , in some embodiments, rib strips 340 are provided on the outer wall surface of the driving module 300, and the rib strips 340 extend in the up and down direction. And a card slot 150 is provided on the inner wall surface of the installation cavity, and the card slot 150 is opened upwards. The rib strips 340 can be inserted downward into the card slot 150 from above the card slot 150 to align the driving module 300 with the mounting shell 100 to achieve the function of anti-misassembly. Moreover, after installation, under the limiting action of the card slot 150 and the rib strips 340, the driving module 300 cannot rotate relative to the mounting shell 100.

[0076] The card slot 150 of this embodiment is located above the installation surface 110.

[0077] Refer to Figure 4 , in some embodiments, the quickly detachable downlight further includes a sealing ring 800. The sealing ring 800 is arranged on the inner peripheral wall surface of the installation cavity, and the inner peripheral wall surface of the sealing ring 800 is connected to the outer peripheral wall surface of the light source module 200.

[0078] It can be understood that the setting of the sealing ring 800 can improve the waterproof and fireproof performance of the quickly detachable downlight, with higher safety. Moreover, it can increase the friction between the light source module 200 and the inner wall of the installation cavity, so that the light source module 200 is more stably installed in the installation cavity and will not automatically fall out from the lower end of the installation cavity.

[0079] The sealing ring 800 can be made of rubber material, silicone material, etc., and is not specifically limited here.

[0080] In some embodiments, the detachable downlight further includes a cover 500, which is detachably mounted on the lower end of the mounting shell 100 and supports the light source module 200, thereby improving the aesthetics of the product and its safety, and preventing the light source module 200 from automatically falling downward. It is understandable that the cover 500 is provided with a light-transmitting hole 510, which runs through the upper and lower end surfaces of the cover 500 and is connected to the mounting cavity. When in use, the light emitted by the light source module 200 in the mounting cavity can be emitted from the light-transmitting hole 510.

[0081] Reference Figure 6 In this embodiment, a connecting plate 140 is disposed at the lower end of the mounting shell 100.

[0082] A bayonet 530 is provided on the upper wall of the connection groove 520, and the bayonet 530 is provided corresponding to the block 141. When the cover 500 is rotated, the cover 500 can slide relative to the groove wall of the connection groove 520, and the bayonet 530 can be aligned or staggered with the block 141. When the bayonet 530 and the block 141 are aligned with each other, the cover 500 can be disassembled downward, so that the connecting plate 140 is disengaged from the connection groove 520, which is convenient for replacing the cover 500 and disassembling the light source module 200 in the installation cavity. When the bayonet 530 and the block 141 are staggered with each other, the block 141 can abut against the upper groove wall of the connection groove 520, and the upper groove wall of the connection groove 520 and the block 141 are mutually restricted, so that the cover 500 can be prevented from being disengaged downward, and a stable connection between the cover 500 and the installation shell 100 is achieved.

[0083] It can be understood that when the face cover 500 is installed at the lower end of the mounting shell 100, the lower groove wall of the connecting groove 520 abuts against the lower end surface of the light source module 200. Since the connection between the face cover 500 and the mounting shell 100 is stable, the face cover 500 can provide an upward supporting force for the light source module 200, thereby further preventing the light source module 200 from automatically falling out of the mounting cavity, making the use process safer.

[0084] It is understandable that the cover 500 can have different colors, designs, patterns, etc., with a variety of choices, so that the quickly detachable downlight can be suitable for scenes of different styles, and users can choose according to their own preferences or needs.

[0085] In some embodiments, the quickly detachable downlight includes a waterproof ring 600. The waterproof ring 600 is disposed in the connection groove 520 and connected to the upper surface of the connection plate 140. By providing the waterproof ring 600, the situation of water entering the installation cavity can be further avoided, the waterproof performance of the quickly detachable downlight can be improved, and thus the service life of the quickly detachable downlight can be extended.

[0086] In this embodiment, the light source module 200 includes a housing, a light source board, a lens, and a condenser cover. Among them, the light source board is provided with light-emitting components, such as LED lamp beads, etc. The socket 210 is disposed on the light source board, and the driving module 300 is electrically connected to the socket 210 of the light source board through the pin 310. The housing is hollow to form a cavity, and both the upper and lower ends of the cavity are open structures. The light source board abuts against the upper end surface of the housing, and the light-emitting components are located in the middle position above the cavity. In this embodiment, the main body of the light source board is an aluminum plate, and the lower surface of the heat-conducting sheet 700 is connected to the upper surface of the light source board, which can improve the heat dissipation effect of the light source board.

[0087] Two upwardly protruding third hooks are provided on the upper end surface of the housing. The two third hooks are disposed on opposite sides of the light source board. Each third hook has a hook portion, and the hook portions of the two third hooks protrude towards the central axis of the housing. The hook portions of the third hooks can be clamped on the upper surface of the light source board, thereby realizing a stable connection between the light source board and the housing.

[0088] In this embodiment, in order to facilitate the setting of the third hooks and ensure the compactness of the overall structure of the quickly detachable downlight, two relief holes are provided on the installation surface 110. The relief holes penetrate the upper and lower surfaces of the installation surface 110. When the light source module 200 is installed in the installation cavity, the two third hooks are respectively aligned with the positions of the two relief holes, and the third hooks can pass through the relief holes and extend above the installation surface 110, which can not only play a positioning role for the light source module 200 but also ensure the compactness and rationality of the structure of the quickly detachable downlight.

[0089] The condenser cover has a trumpet shape with a smaller upper part and a larger lower part. It is installed on the lower side of the light source board. The upper end of the condenser cover abuts against the lower surface of the main body of the light source board and is sleeved on the outer periphery of the light-emitting components, which can condense the light emitted by the light-emitting components, avoid light leakage, and achieve a better illumination effect.

[0090] The lens is installed in the cavity and is located below the condenser cover. The light condensed by the condenser cover passes through the lens and irradiates out. The lens can not only protect the light-emitting components but also enrich the light effect, making the quickly detachable downlight applicable to more different scenarios.

[0091] In this embodiment, the lower groove wall of the connection groove 520 of the face cover 500 abuts against the lower end surface edge of the lens, and the face cover 500 can support the lens.

[0092] In some embodiments, a junction box is connected to the driving module 300, and the junction box is used to realize the electrical connection between the driving module 300 and an external power supply and circuit. It can be understood that the junction box is a common component in the art, and those skilled in the art should be clear about its structure and principle, so the junction box will not be elaborated too much here.

[0093] The quickly detachable downlight of the embodiment of the present utility model can realize the quick detachment of the driving module 300 and the light source module 200, so as to facilitate the maintenance or replacement of the driving module 300 and the light source module 200. The specific detachment process is as follows: Press the two pressing blocks 330 protruding from the outside of the driving module 300, so that the hook parts of the two second hooks 320 move towards each other, making the hook part of the first hook 130 separate from the hook part of the second hook 320. Pull up the driving module 300, and the pins 310 of the driving module 300 come out of the socket 210 of the light source module 200, and the conductive connection between the driving module 300 and the light source module 200 is disconnected. The driving module 300 is removed from above the mounting shell 100, and the button 410 is exposed. Rotate the face cover 500 to align the bayonet 530 of the face cover 500 with the latch 141 of the connecting plate 140, and detach the face cover 500 from the mounting shell 100 downward. Press the button 410 downward, and the push rod 420 moves downward with the button 410 and contacts the light source module 200. The push rod 420 pushes the light source module 200 downward, so that the light source module 200 completely comes out of the mounting cavity, realizing the removal of the light source module 200.
