Description

Technical Field

[0001] The utility model relates to the technical field of lamps, in particular to a detachable fireproof downlight. Background Art

[0002] The existing downlights are divided into two types: integral type and split type. The integral downlight utilizes the close contact between the light source component and the heat dissipation cylinder body to achieve good heat dissipation function. However, when one or more components are damaged, the entire downlight needs to be discarded and replaced, resulting in waste of resources. For the split downlight, each structure can be separated from each other. When one or more components are damaged, only the damaged components need to be replaced, and the other undamaged components can continue to be used, greatly reducing the cost of later maintenance and waste of resources. However, since the various structures of the split downlight can be separated from each other, the structure for heat dissipation cannot ensure good contact with the light source component, thus failing to take into account the heat dissipation problem and the fireproof performance needs to be improved.

[0035] Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all embodiments. Based on the embodiments of the present utility model, other embodiments obtained by those skilled in the art without creative efforts all belong to the scope protected by 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.

[0036] Refer to Figure 1 and Figure 2 As shown in [relevant reference], an embodiment of the present utility model provides a detachable fireproof downlight, which includes a driving module 200, a light source module 300, and a fireproof bracket 100. When one of the driving module 200 or the light source module 300 is damaged, the damaged module can be disassembled and replaced separately. Moreover, the fireproof bracket 100 can provide a good heat dissipation effect for the light source module 300, and there is no need to separately set a radiator, thus solving the problem that the existing split downlights cannot take into account heat dissipation, and improving the safety performance of the downlight while taking into account economy.

[0037] Refer to Figure 3 As shown in [relevant reference], in this embodiment, the fireproof bracket 100 is provided with an installation cavity 110, and the installation cavity 110 is arranged to open downward. The driving module 200 is detachably installed on the fireproof bracket 100 and is located outside the installation cavity 110, and is detachably connected to the upper wall surface of the installation cavity 110. Refer to Figure 4 、 Figure 5 and Figure 6, the light source module 300 includes a lens assembly, an elastic member, and a light-emitting source 330. Among them, the lens assembly is provided with a light-emitting cavity, and the upper end surface of the light-emitting cavity is provided with heat dissipation holes 321. The lens assembly is detachably connected to the installation cavity 110. The light-emitting source 330 is used for emitting light to achieve the lighting function. It is arranged in the light-emitting cavity and covers the lower side of the heat dissipation holes 321. The light-emitting source 330 abuts against the upper wall surface of the light-emitting cavity. One end of the elastic member is connected to the lower wall surface of the light-emitting cavity, and the other end abuts against the lower wall surface of the light-emitting source 330.

[0038] It can be understood that since both the driving module 200 and the light source module 300 are detachably connected to the fireproof bracket 100, when the driving module 200 or the light source module 300 is damaged, the damaged module can be detached from the fireproof bracket 100 for replacement, and the modules with good performance can still be used, greatly reducing the later maintenance cost and also reducing the waste of resources.

[0039] It should be noted that referring to Figure 3 and Figure 9 , in this embodiment, the upper wall surface of the installation cavity 110 is provided with a contact platform 120, and the contact platform 120 protrudes downward. When the light source module 300 is installed in the installation cavity 110, the contact platform 120 passes through the heat dissipation holes 321 downward and abuts against the light-emitting source 330. It can be understood that under the elastic action of the elastic member, the light-emitting source 330 can maintain good contact with the contact platform 120, thus solving the heat dissipation problem and improving the fireproof performance.

[0040] In this embodiment, the elastic member is a buffer spring 340, and the buffer spring 340 can provide about 2 mm of buffer space for the light-emitting source 330 up and down, so that the light-emitting source 330 is kept in contact with the fireproof bracket 100, ensuring heat dissipation.

[0041] It can be understood that the fireproof bracket 100 is made of heat-dissipating materials such as metal. In this embodiment, the fireproof bracket 100 is an iron bracket.

[0042] In some embodiments, referring to Figure 4 and Figure 6 , the light source module 300 further includes a heat-conducting sheet 350, and the heat-conducting sheet 350 covers the upper surface of the light-emitting source 330. When the light source module 300 is installed in the installation cavity 110, the heat-conducting sheet 350 is located at the position between the upper wall surface of the light-emitting source 330 and the contact platform 120 of the installation cavity 110, and the contact platform 120 abuts against the upper surface of the heat-conducting sheet 350.

[0043] It can be understood that by providing the heat-conducting sheet 350, the heat dissipation effect can be further improved, thereby further improving the fireproof performance of the downlight.

[0044] In this embodiment, the heat-conducting sheet 350 is a heat-conducting silica gel sheet.

[0045] Referring to Figure 4 , Figure 5 , Figure 6 and Figure 9 , in some embodiments, the lens assembly includes a lens body 310 and a gland 320. The gland 320 is detachably connected to the lens body 310 and together forms a light-emitting cavity. Among them, the gland 320 forms the upper wall surface of the light-emitting cavity. A heat dissipation hole 321 is provided on the gland 320 and penetrates the upper and lower surfaces of the gland 320. The lens body 310 is detachably connected to the fireproof bracket 100.

[0046] It can be understood that with such a setting, after the lens assembly is taken out of the installation cavity 110, by detaching the gland 320 and the lens body 310, the elastic member and the light source 330 inside the light-emitting cavity can be exposed, so as to facilitate the maintenance of the elastic member and the light source 330, and also facilitate the removal of the elastic member and the light source 330 from the installation cavity 110.

[0047] It can be understood that the gland 320 and the lens body 310 can be detachably connected by connecting members such as snap members and screws.

[0048] In this embodiment, the gland 320 and the lens body 310 are connected by screws. The lens body 310 is provided with a plurality of mounting posts. The mounting posts are located inside the light-emitting cavity and extend in the up-and-down direction. The lower ends thereof are connected to the lower end surface of the light-emitting cavity. The mounting posts are provided with screw holes opening upward. A through-hole structure is correspondingly provided on the gland 320. The screw passes through the through-hole structure on the gland 320 and cooperates with the screw hole of the mounting post to realize the connection between the gland 320 and the lens body 310.

[0049] In the above embodiment, further, the mounting posts play a guiding role for the buffer spring 340. The buffer spring 340 is sleeved on the corresponding mounting posts, and the buffer spring 340 is restricted from being compressed in the up-and-down direction by the mounting posts. It can be understood that since the upper end of the buffer spring 340 abuts against the lower surface of the light source 330 and the mounting posts for guiding are located below the light source 330, a through-hole structure needs to be provided at the corresponding position of the light source 330 to facilitate the screw for connecting the gland 320 and the lens body 310 to pass through.

[0050] In this embodiment, four buffer springs 340 are provided. The four buffer springs 340 are respectively located at the four corners of the light source 330, and three mounting posts are provided. Two of the mounting posts are located at two corners of the light source 330, and the other mounting post is located outside the light source 330. The three mounting posts form a triangular structure. By connecting the gland 320 and the lens body 310 with screws, the stability of the connection between the gland 320 and the lens body 310 can be ensured. Two of the buffer springs 340 are sleeved on the outer periphery of the mounting posts located at two corners of the light source 330. At the other two corners of the light source 330, guide posts are also provided. The guide posts extend in the up and down directions, and the lower ends of the guide posts are connected to the lower wall surface of the light-emitting cavity. The other two buffer springs 340 are respectively sleeved on the outer peripheries of the two guide posts. The guide posts can play a role in restricting the compression of the buffer springs 340 in the up and down directions.

[0051] In some embodiments, the lens assembly is provided with a connecting member that protrudes upward. A block 311 is provided at the upper end of the connecting member. The upper wall surface of the installation cavity 110 is provided with a chute 122 and a disassembly and assembly opening 123. The disassembly and assembly opening 123 is provided at the side of the chute 122 and is communicated with the chute 122. When the lens assembly is installed into the installation cavity 110, the connecting member extends upward through the chute 122 and is slidably connected within the chute 122. The lower end of the block 311 can abut against the upper wall surface of the fireproof bracket 100.

[0052] The lens assembly can rotate relative to the fireproof bracket 100. The chute 122 is arc-shaped. During the rotation of the lens assembly relative to the fireproof bracket 100, the connecting member slides along the chute 122. It can be understood that the block 311 matches the disassembly and assembly opening 123. When the lens assembly rotates relative to the fireproof bracket 100 to a position where the block 311 corresponds to the disassembly and assembly opening 123, the block 311 can enter and exit the disassembly and assembly opening 123.

[0053] Specifically, during the installation process, align the block 311 with the disassembly and assembly opening 123, then insert the lens assembly upward into the installation cavity 110, and rotate the lens assembly to stagger the block 311 from the disassembly and assembly opening 123. The lower end surface of the block 311 abuts against the upper wall surface of the fireproof bracket 100, and the lens assembly cannot be disengaged downward from the installation cavity 110, thereby realizing the stable connection between the lens assembly and the fireproof bracket 100. During the disassembly process, rotate the lens assembly to make the block 311 correspond to the disassembly and assembly opening 123, and then apply a downward force to the lens assembly. The lens assembly can be disengaged from the installation cavity 110, realizing the separation between the light source module 300 and the fireproof bracket 100.

[0054] In this embodiment, the connecting member is installed on the lens body 310. A relief groove is provided at the corresponding position of the gland 320. The relief groove penetrates the upper and lower surfaces of the gland 320. The connecting member extends upward and passes through the relief groove to reach the sliding groove 122 on the upper wall surface of the installation cavity 110.

[0055] In this embodiment, there are two connecting members, and the two connecting members are symmetrically arranged on the left and right sides of the lens body 310. Two corresponding sliding grooves 122 are also provided on the upper wall surface of the installation cavity 110.

[0056] In some embodiments, the light source module 300 further includes a snap spring 370. The snap spring 370 includes a pulling rod 372 and a connecting rod 371. There are two connecting rods 371. The two connecting rods 371 are located at both ends of the pulling rod 372 and are on the same straight line. The two connecting rods 371 are respectively rotatably connected to the lens assembly. The pulling rod 372 can rotate around the straight line where the connecting rod 371 is located.

[0057] Specifically, when it is necessary to remove the light source module 300 from the installation cavity 110, rotating the pulling rod 372 of the snap spring 370 downward can facilitate the operator to apply force to the light source module 300, facilitate controlling the rotation of the lens assembly relative to the fireproof bracket 100, and is beneficial to pulling the light source module 300 downward out of the installation cavity 110, further improving the convenience of disassembling and assembling the light source module 300. After the installation of the light source module 300 is completed, rotating the pulling rod 372 upward can make the main body of the pulling rod 372 in a horizontal state or close to the lower surface of the lens assembly. The pulling rod 372 will not block directly below the light emitting source 330, and can avoid the pulling rod 372 affecting the lighting effect of the light source module 300.

[0058] In this embodiment, the pulling rod 372 is in a semi-circular ring shape. When the pulling rod 372 rotates to the horizontal state, the pulling rod 372 just makes room for the lower part of the light emitting source 330.

[0059] In some embodiments, a support block 312 is provided at the lower end of the lens assembly, specifically on the lower wall surface of the lens body 310. The support block 312 protrudes downward. When the pulling rod 372 rotates to the position where it abuts against the support block 312, the pulling rod 372 will not block the illumination of the light emitting source 330. Moreover, a gap is formed between the pulling rod 372 and the lower end surface of the lens assembly, and the pulling rod 372 is in a hovering state, which is more convenient for the operator to reach the position between the pulling rod 372 and the lower end surface of the lens assembly to facilitate rotating the pulling rod 372.

[0060] In some embodiments, the light source module 300 further includes a switch 360. The switch 360 is electrically connected to the light source 330 and extends downward to the lower side of the lens assembly for easy operation by the user. In this embodiment, the switch 360 is a color temperature DIP switch 360 that can control the color temperature adjustment of the light source 330.

[0061] In some embodiments, the switch 360 and the support block 312 are respectively disposed on both sides of the straight line where the connecting rod 371 is located. Specifically, in this embodiment, the switch 360 is located on the front side of the connecting rod 371, while the support block 312 is located on the rear side of the connecting rod 371. A stop plate 313 is further disposed on the lower end surface of the lens assembly. The stop plate 313 is disposed on the side of the straight line where the connecting rod 371 is located close to the switch 360, and can limit the rotation of the pull rod 372 to prevent the pull rod 372 from rotating to the side of the switch 360, thereby avoiding the mutual interference between the switch 360 and the pull rod 372.

[0062] Refer to Figure 3 and Figure 5 In some embodiments, alignment blocks 130 are provided on the inner wall surface of the installation cavity 110. The alignment blocks 130 are disposed at the lower end of the installation cavity 110. Alignment grooves 314 are provided on the outer wall surface of the lens assembly, and the alignment grooves 314 are matched with the alignment blocks 130.

[0063] It can be understood that the arrangement of the alignment blocks 130 and the alignment grooves 314 can provide disassembly and assembly prompts for the operator. During the installation of the light source module 300, first align the positions of the alignment grooves 314 and the alignment blocks 130, and then insert the light source module 300 upward into the installation cavity 110. At this time, the positions of the locking blocks 311 and the disassembly and assembly openings 123 correspond. When the lens assembly is installed on the upper end of the alignment block 130, the locking blocks 311 extend upward from the disassembly and assembly openings 123 to above the sliding grooves 122. Moreover, the lens assembly can rotate relative to the fireproof bracket 100, that is, the connecting member can slide along the sliding grooves 122. Rotate the lens assembly to a position where the alignment grooves 314 and the alignment blocks 130 are misaligned, and the locking blocks 311 abut against the upper wall surface of the fireproof bracket 100, and the lens assembly is stably connected to the fireproof bracket 100, and the light source module 300 cannot be disengaged downward from the installation cavity 110.

[0064] During the disassembly of the light source module 300, rotate the light source module 300 relative to the fireproof bracket 100 to make the positions of the alignment blocks 130 and the alignment grooves 314 correspond. At this time, the positions of the locking blocks 311 and the disassembly and assembly openings 123 correspond. Pull the light source module 300 downward, and the locking blocks 311 can be disengaged downward from above the disassembly and assembly openings 123, realizing the detachment of the light source module 300 from the fireproof bracket 100.

[0065] In this embodiment, there are two alignment blocks 130 symmetrically arranged, and two corresponding alignment grooves 314 are also provided.

[0066] In some embodiments, the light source module 300 further includes a waterproof ring 380. The waterproof ring 380 is disposed on the upper end surface of the lens body 310 and can block the gap between the edge of the lens body 310 and the edge of the gland 320. When the light source module 300 is installed in the installation cavity 110, the waterproof ring 380 abuts against the upper wall surface of the installation cavity 110 to improve the waterproof performance of the detachable fireproof downlight.

[0067] In some embodiments, an indication mark is provided on the lower end surface of the lens body 310, such as an arrow pattern indicating the rotation of the lens body 310, an unlocking pattern, a locking pattern, text, etc., to facilitate disassembly and assembly by the user.

[0068] Referring to Figure 7 and Figure 3 , in some embodiments, the driving module 200 is provided with a hook 210 which extends downward. A clamping groove 121 and a notch are provided on the upper wall surface of the installation cavity 110. The notch is provided at the edge of the clamping groove 121 and is communicated with the clamping groove 121. The hook 210 passes downward through the clamping groove 121 and is clamped with the upper wall surface of the installation cavity 110. It can be understood that the hook 210 and the notch match each other. The hook 210 can move along the clamping groove 121 and enter and exit the clamping groove 121 through the notch, so as to realize the detachable connection between the driving module 200 and the fireproof bracket 100.

[0069] In this embodiment, the clamping groove 121 is arc-shaped. When the driving module 200 is rotated relative to the fireproof bracket 100 so that the positions of the hook 210 and the notch correspond, applying an upward pulling force to the driving module 200 can detach the driving module 200 from the fireproof bracket 100, and the operation is simple and fast. During the installation of the driving module 200, when the positions of the hook 210 and the notch correspond, and then the driving module 200 is rotated so that the positions of the hook 210 and the notch are staggered, the hook 210 can be stably clamped with the upper wall surface of the installation cavity 110, realizing the stable connection between the driving module 200 and the fireproof bracket 100.

[0070] In this embodiment, the driving module 200 is provided with two hooks 210 which are symmetrically arranged on both sides of the driving module 200. Correspondingly, two sets of clamping grooves 121 and notches are also provided, which can further improve the connection stability between the driving module 200 and the fireproof bracket 100.

[0071] In this embodiment, two groups of card slots 121 and two groups of sliding slots 122 communicate with each other in a one-to-one correspondence. The disassembly and assembly ports 123 and the notches corresponding to the mutually communicating sliding slots 122 and card slots 121 are located at the same position, that is, the hooks 210 of the driving module 200 and the clamping blocks 311 of the lens assembly are disengaged from the fireproof bracket 100 at the same position. Such a setting is beneficial to the processing of the fireproof bracket 100. The holes opened on the fireproof bracket 100 are reduced, simplifying the processing technology of the fireproof bracket 100, and can also ensure that the heat conduction area on the fireproof bracket 100 meets the requirements, guaranteeing the fireproof effect of the detachable fireproof downlight.

[0072] In some embodiments, the driving module 200 is further provided with quick insertion terminals 220. A quick insertion port 124 is provided on the upper wall surface of the installation cavity 110. The quick insertion terminals 220 enter the installation cavity 110 through the quick insertion port 124 and are electrically connected to the light source module 300.

[0073] It can be understood that the quick insertion terminals 220 are electrically connected to the circuit board of the driving module 200 through wires. Since the wires can be bent, the rotation of the driving module 200 relative to the fireproof bracket 100 will not damage the electrical connection between the quick insertion terminals 220 and the light source module 300.

[0074] In this embodiment, the quick insertion terminals 220 are inserted and conductively connected to the switch 360 of the light source module 300. After separating the driving module 200 from the fireproof bracket 100, directly pull out the quick insertion terminals 220 upward from the switch 360, and the separation between the driving module 200 and the light source module 300 can be achieved.

[0075] Refer to Figure 1 、 Figure 2 、 Figure 8 and Figure 9 In some embodiments, the detachable fireproof downlight further includes a face cover 400. The face cover 400 is arranged at the lower end of the fireproof bracket 100 and is clamped with the fireproof bracket 100. When the face cover 400 is installed at the lower end of the fireproof bracket 100, the face cover 400 can block the gap between the lens assembly and the inner wall of the installation cavity 110 to improve the fireproof and waterproof performance of the detachable fireproof downlight. In this embodiment, the face cover 400 can also block the lower part of the switch 360 and the snap spring 370, further improving the aesthetics and safety of the detachable downlight.

[0076] It can be understood that a light transmission port 410 is provided in the middle of the face cover 400. The light emitting source 330 is arranged above the light transmission port 410. The light emitted by the light emitting source 330 is irradiated out through the light transmission port 410 after passing through the lens assembly.

[0077] In some embodiments, a connecting ring 420 is provided on the outer periphery of the light-transmitting opening 410. The connecting ring 420 protrudes upward. An outwardly protruding clamping wall 430 is provided on the outer peripheral wall surface of the connecting ring 420. A connecting groove 440 is formed on the lower side of the clamping wall 430. When the face cover 400 is installed at the lower end of the fireproof bracket 100, by rotating the face cover 400, the alignment block 130 can enter the connecting groove 440 and abut against the lower end surface of the clamping wall 430, thereby realizing the detachable connection between the face cover 400 and the fireproof bracket 100.

[0078] In this embodiment, two limiting walls 450 are provided, which can form two connecting grooves 440 to correspond to the clamping of the two alignment blocks 130, improving the connection stability between the face cover 400 and the fireproof bracket 100.

[0079] In this embodiment, a limiting wall 450 is provided at one end of the clamping wall 430. The limiting wall 450 can close one end opening of the connecting groove 440. When the face cover 400 rotates relative to the fireproof bracket 100 to the position where the alignment block 130 abuts against the limiting wall 450, the face cover 400 cannot continue to rotate in the original rotation direction. At this time, the face cover 400 is installed in place, and the connection between the face cover 400 and the fireproof bracket 100 is stable.

[0080] In some embodiments, the detachable fireproof downlight further includes a junction box 500. The junction box 500 is plugged into the driving module 200 to facilitate connecting the detachable fireproof downlight to the home circuit. In this embodiment, the junction box 500 is a high-voltage terminal junction box.

[0081] The above has specifically described the preferred embodiments of the present invention, but the present invention is not limited to the above embodiments. Those skilled in the art can also make various equivalent modifications or substitutions without departing from the spirit of the present invention, and these equivalent modifications or substitutions are all included within the scope defined by the claims of this application.
