Description

Technical Field

[0001] The present invention relates to the technical field of smart home lighting, and particularly relates to a smart home lighting system. Background Art

[0002] With the continuous progress of technology and the improvement of people's living standards, smart home technology has gradually entered daily life, changing people's living environment and lifestyle. As an important part of smart home, the smart home lighting system has the characteristics of energy saving, comfort, safety and convenience, and has been widely used in various places such as homes, offices and commercial areas. Downlights are widely used in smart home lighting systems. A downlight usually consists of a light bulb, a lamp holder, a heat dissipation device, a housing, etc.

[0003] In the patent (application number: CN201811625483.9), a downlight is disclosed. Both this downlight and the existing downlights are fixed in the installation holes of the ceiling by spring buckles. During installation, it is necessary to hold the two spring buckles open by hand and then keep them open, and then place them into the reserved holes of the ceiling for installation before the acting force on the spring buckles can be released, which is inconvenient for installation; during disassembly, tools are needed to pry the downlight off, and during the prying process, it is easy to damage the ceiling and the downlight; at the same time, due to the limited fixing area of the spring buckles and the fact that a relatively large elastic force is required to fix the downlight, the downlight can only be fixed on a ceiling with a relatively large thickness. In actual installation, there may be a situation where the ceiling is relatively thin, and in this case, the downlight cannot be installed, so the installation is rather limited. Summary of the Invention

[0004] The purpose of the present invention is to provide a smart home lighting system to solve the above problems.

[0005] The present invention specifically adopts the following technical solutions to achieve the above purpose:

[0006] A smart home lighting system includes a downlight. The upper half of the downlight is provided with heat dissipation fins, and the lower half of the downlight is rotatably installed with a bottom ring. A clamping top ring is slidably connected to the top of the bottom ring, and a top spring is arranged between the clamping top ring and the bottom ring.

[0007] A support sleeve is fixedly installed on the top of the bottom ring, and the clamping top ring is sleeved outside the support sleeve. The outer wall of the support sleeve is penetrated with an upper spiral groove and a lower spiral groove. The upper spiral groove and the lower spiral groove have opposite spiral directions. The lower end of the upper spiral groove and the upper end of the lower spiral groove are both provided with guiding outlets, and the two groups of guiding outlets are on the same horizontal plane. An upper support bar is slidably connected inside the upper spiral groove, and a lower support bar is slidably connected inside the lower spiral groove. Sliders are fixedly installed on the inner sides of the upper support bar and the lower support bar, and the sliders are slidably connected to the heat dissipation fins.

[0008] Furthermore, a guiding member and a support ring are provided outside the guiding outlet.

[0009] Furthermore, the guiding member is composed of a mounting portion, a buffering portion and a supporting portion. The support ring is sleeved on the supporting portion, and an arc chamfer is provided at the outer end of the supporting portion.

[0010] Furthermore, when the upper support bar and the lower support bar are wound up, the cross section is arc-shaped and larger than a semi-circle.

[0011] Furthermore, the heat dissipation fins, the upper support bar, the lower support bar and the slider are all made of brass.

[0012] Furthermore, a heat dissipation gap is provided between the support sleeve and the heat dissipation fins, and the slider is inserted into the heat dissipation gap.

[0013] Furthermore, an outer convex ring is provided on the lower half of the downlight. A rotating groove is provided at the bottom of the bottom ring, and the outer convex ring is inserted into the rotating groove. An installation ring is threadedly connected inside the rotating groove, and a driving slot is provided at the bottom of the installation ring.

[0014] Furthermore, a friction groove is provided on the lower half of the downlight, and the friction groove is located below the bottom ring.

[0015] Furthermore, rollers are provided on the inner walls of the upper spiral groove and the lower spiral groove.

[0016] The beneficial effects of the present invention are as follows:

[0017] 1. In the present invention, by pressing the bottom ring and the clamping top ring against the ceiling, and then rotating the downlight, the downlight drives the two sliders to rotate through the heat dissipation fins. The two sliders respectively drive the upper support bar and the lower support bar to slide along the upper spiral groove and the lower spiral groove. The upper support bar and the lower support bar extend from both sides of the support sleeve. After extension, the upper support bar and the lower support bar are wound into an arc shape. At this time, the upper support bar and the lower support bar play a supporting role. Then, loosening the bottom ring can complete the installation. The installation is convenient, and when disassembling, just reverse the downlight to retract the upper support bar and the lower support bar. The installation and disassembly are convenient.

[0018] 2. Through the settings of the upper spiral groove, the lower spiral groove, the upper support bar and the lower support bar, the present invention can adjust the support length of the downlight according to needs, with high installation stability. At the same time, through this design, the downlight can be installed on a thin ceiling, and the installation range is wide.

[0019] 3. By using the upper support bar and the lower support bar as extended heat dissipation members, the present invention can quickly direct the heat generated by the downlight to a wider space, and the heat dissipation effect is good. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners

[0028] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0029] Embodiment 1, as Figures 1-7 shown, a smart home lighting system includes a downlight 1. The upper half of the downlight 1 is provided with heat dissipation fins 11. The lower half of the downlight 1 is rotatably installed with a bottom ring 2. The top of the bottom ring 2 is slidably connected with a clamping top ring 3. A top spring 31 is arranged between the clamping top ring 3 and the bottom ring 2;

[0030] The top of the bottom ring 2 is fixedly installed with a support sleeve 4. The clamping top ring 3 is sleeved outside the support sleeve 4. The outer wall of the support sleeve 4 is penetrated with an upper spiral groove 41 and a lower spiral groove 42. The upper spiral groove 41 and the lower spiral groove 42 have opposite spiral directions. The lower end of the upper spiral groove 41 and the upper end of the lower spiral groove 42 are both provided with guide outlets. The two groups of guide outlets are on the same horizontal plane. An upper support bar 5 is slidably connected inside the upper spiral groove 41. A lower support bar 6 is slidably connected inside the lower spiral groove 42. The inner sides of the upper support bar 5 and the lower support bar 6 are both fixedly installed with sliders 51. The sliders 51 are slidably connected to the heat dissipation fins 11.

[0031] Furthermore, the heat dissipation fins 11, the upper support bar 5, the lower support bar 6 and the slider 51 are all made of brass.

[0032] Installation: Insert the support sleeve 4 into the installation hole, make the clamping top ring 3 press against the suspended ceiling, then push the bottom ring 2 upward. The bottom ring 2 rises relative to the clamping top ring 3 and compresses the top spring 31, so that the upper support bar 5 and the lower support bar 6 exceed the upper surface of the suspended ceiling. Then rotate the downlight 1. The downlight 1 rotates relative to the bottom ring 2. The downlight 1 drives the two groups of sliders 51 to rotate through the heat dissipation fins 11. The two groups of sliders 51 drive the upper support bar 5 and the lower support bar 6 to rotate synchronously. It should be noted that the slider 51 on the upper support bar 5 is located at the upper end of the upper support bar 5, and the slider 51 on the lower support bar 6 is located at the lower end of the lower support bar 6. Since the spiral directions of the upper spiral groove 41 and the lower spiral groove 42 are opposite, the upper support bar 5 slides out from the guiding outlet of the upper spiral groove 41 from top to bottom along the upper spiral groove 41, and the lower support bar 6 slides out from the guiding outlet of the lower spiral groove 42 from bottom to top. The two guiding outlets are on the same horizontal plane. Therefore, the upper support bar 5 and the lower support bar 6 extend from both sides of the support sleeve 4, and the extending directions are opposite. When the upper support bar 5 and the lower support bar 6 are in the upper spiral groove 41 and the lower spiral groove 42, they are straight sheets and can be bent. After the upper support bar 5 and the lower support bar 6 extend, they are wound into an arc shape under the action of their own elastic force. The arc-shaped upper support bar 5 and lower support bar 6 have a large bending resistance, so they can generate sufficient supporting force. Control the number of rotation turns of the downlight 1 according to the thickness of the suspended ceiling, and then the extending lengths of the upper support bar 5 and the lower support bar 6 can be controlled. The thinner the suspended ceiling, the longer the extending length, and the larger the area of the suspended ceiling participating in the support. Therefore, it can ensure that the downlight 1 can be installed on a thin suspended ceiling. After the adjustment is completed, loosen the bottom ring 2, and the extended upper support bar 5 and lower support bar 6 press on the upper surface of the suspended ceiling to complete the installation of the downlight 1. The installation is convenient.

[0033] Disassembly: Since the cross-sections of the extended upper support bar 5 and the lower support bar 6 are arc-shaped, only rotate the downlight 1 relative to the bottom ring 2. The downlight 1 retracts the upper support bar 5 and the lower support bar 6 into the upper spiral groove 41 and the lower spiral groove 42, and then the downlight 1 can be directly removed. The disassembly is convenient.

[0034] It should be noted that the thinner the suspended ceiling, the smaller the distance to push the bottom ring 2 upward during installation. Therefore, only a relatively small pressure is required to make the upper support bar 5 and the lower support bar 6 exceed the upper surface of the suspended ceiling. Therefore, the suspended ceiling will not be damaged by excessive pressure, and the installation stability is high.

[0035] During use, the extended lengths of the upper support bar 5 and the lower support bar 6 can be controlled according to the heat dissipation situation inside the ceiling. Since the heat dissipation fins 11, the upper support bar 5, the lower support bar 6, and the slider 51 are all made of brass, the heat on the heat dissipation fins 11 can be transferred to the upper support bar 5 and the lower support bar 6 through the slider 51. Since the upper support bar 5 and the lower support bar 6 extend horizontally, the heat can be directed to a wider space, resulting in good heat dissipation effect.

[0036] With the settings of the upper spiral groove 41, the lower spiral groove 42, the upper support bar 5, and the lower support bar 6 in the present invention, the upper support bar 5 and the lower support bar 6 can be synchronously extended and retracted within a limited space. The control structure is simple, occupies little space, and does not require changing the structure of the downlight 1 itself, resulting in low manufacturing cost.

[0037] Embodiment 2: On the basis of the above embodiment, it further includes a guide member 7 and a support ring 8 disposed outside the guide outlet.

[0038] Further, the guide member 7 is composed of a mounting portion 71, a buffer portion 72, and a support portion 73. The support ring 8 is sleeved on the support portion 73, and an arc chamfer is provided at the outer end of the support portion 73.

[0039] After passing through the guide outlet, the upper support bar 5 and the lower support bar 6 are first wrapped around the buffer portion 72 and then around the support portion 73, which plays a buffering role for the deformed parts of the upper support bar 5 and the lower support bar 6. The retracted upper support bar 5 and lower support bar 6 pass through the gap between the support ring 8 and the support portion 73. Therefore, the support ring 8 can provide support for the upper support bar 5 and the lower support bar 6, preventing the supporting force from directly acting on the buffer parts of the upper support bar 5 and the lower support bar 6, ensuring high supporting stability.

[0040] Embodiment 3: On the basis of the above embodiment, it further includes that when the upper support bar 5 and the lower support bar 6 are retracted, the cross-section is circular arc-shaped and larger than a semicircle. Through this design, when the upper support bar 5 and the lower support bar 6 are retracted, there can be sufficient supporting force.

[0041] Embodiment 4: On the basis of the above embodiment, it further includes that there is a heat dissipation gap between the support sleeve 4 and the heat dissipation fins 11, and the slider 51 is inserted into the heat dissipation gap. Through this design, the installation of the slider 51 can be completed only by inserting the slider 51 into the heat dissipation gap and on the heat dissipation fins 11 at the same time, which is convenient for installation.

[0042] Embodiment 5: On the basis of the above embodiment, it further includes that an outer convex ring 12 is provided on the lower half of the downlight 1, a rotating groove is provided at the bottom of the bottom ring 2, the outer convex ring 12 is inserted into the rotating groove, an installation ring 21 is threadedly connected inside the rotating groove, and a driving slot is provided at the bottom of the installation ring 21.

[0043] Insert the downlight 1 into the bottom ring 2 from below, and insert the convex ring 12 into the rotating groove. Then, screw the mounting ring 21 into the rotating groove to install the bottom ring 2 on the downlight 1.

[0044] Embodiment 6: On the basis of the above embodiments, it further includes that a friction groove is provided in the lower half of the downlight 1, and the friction groove is located below the bottom ring 2. With this design, it is convenient to rotate the downlight 1.

[0045] Furthermore, rollers are provided on the inner walls of the upper spiral groove 41 and the lower spiral groove 42. With this design, the friction between the upper support bar 5 and the lower support bar 6 in the upper spiral groove 41 and the lower spiral groove 42 is reduced.

[0046] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be obvious to those skilled in the art, and the general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to these embodiments shown herein, but will be accorded the widest scope consistent with the principles and novel features disclosed herein.
