Specific embodiments

[0033] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0034] Embodiment 1: Please refer to Figure 1 , the present invention provides the following technical solutions: A magnetic suction type downlight housing assembly includes an embedded outer ring component. The outer ring component includes: a first outer ring base 1a, a first magnet 2a, a first outer ring head 3a, and a spring buckle 4. The spring buckles 4 are symmetrically arranged on the top of the first outer ring head 3a. A first magnet 2a is pad-mounted inside the first outer ring head 3a in a fitting manner, and the first outer ring head 3a is threadedly connected to the first outer ring base 1a to clamp and fix the first magnet 2a. An inner liner component is magnetically connected inside the outer ring component, and a light shielding component is snap-connected to the bottom of the inner liner component;

[0035] As Figure 2 shown, the inner liner component includes: a first inner liner cylinder 5, a second magnet 6, a second inner liner cylinder 7, and a clamping portion 10. The cross-section of the first inner liner cylinder 5 is convex. An arc-shaped notch is opened at the opening edge of the protruding end at the top, and through holes are symmetrically opened in the axial direction of the arc-shaped notch. Two threaded holes are symmetrically opened on the outer extension of the top surface of the first inner liner cylinder 5. The second magnet 6 is sleeved on the outer extension of the top surface of the first inner liner cylinder 5 and is fixed by threaded connection between the bolts passing through its interior and the threaded holes;

[0036] As Figure 4 , Figure 12As shown, the cross-section of the inner liner cylinder two 7 is in an inverted convex shape and is inserted into the top opening end of the inner liner cylinder one 5. An arc-shaped connecting ear is provided on the outer extension surface of its bottom. And threaded holes are symmetrically opened on the surface of the arc-shaped connecting ear, which are adapted to the positions and sizes of the through holes opened on the inner liner cylinder one 5. By inserting bolts into the through holes and threadedly connecting them with the threaded holes, the rotational connection between the inner liner cylinder two 7 and the inner liner cylinder one 5 can be realized. At the same time, the rotational fixation between the inner liner cylinder two 7 and the inner liner cylinder one 5 is realized through the tightening force between the bolts and the threaded holes, which is used to change the irradiation angle of the downlight. The top edge of the inner liner cylinder two 7 is provided with elastic pieces arranged at equal intervals in a ring shape, which are used to fix the LED lamp bead module. By pressing the LED lamp bead module into the top opening end of the inner liner cylinder two 7 and through the extrusion of the elastic pieces, the fixation of the LED lamp bead module can be realized, as Figure 13 shown;

[0037] As Figure 3 shown, the clamping part 10 is arranged on the inner wall of the inner liner cylinder one 5, and the clamping part 10 is a circular ring with a right trapezoidal cross-section; the light-shielding component includes: a light-shielding disc 8 and a buckle 9. There are three groups of buckles 9, and they are arranged at equal intervals in a ring shape. The buckle 9 is vertically connected to the top surface of the light-shielding disc 8. When the light-shielding component is inserted into the bottom opening end of the inner liner cylinder one 5, a clamping connection is formed between the buckle 9 and the clamping part 10 through the deformation of the buckle 9, and the convenient disassembly and assembly combination between the light-shielding component and the inner liner component can be realized;

[0038] During specific use: The outer ring component is fixed in the hole opened on the ceiling by using the spring buckle 4, and then the inner liner component is inserted into the outer ring component. Through the magnetic attraction between the first magnet 2a and the magnet two 6, the installation of the inner liner component is realized. Finally, the light-shielding disc 8 is clamped into the bottom of the inner liner cylinder one 5 of the inner liner component by using the buckle 9 to realize the installation and fixation of the entire downlight.

[0039] Embodiment two: As Figure 5 、 Figure 6As shown, in addition to using the embedded outer ring component in the first embodiment, a borderless outer ring component can also be used, including: a second outer ring base 1b, a second magnet 2b, and a second outer ring head 3b. The second magnet 2b is adhesively disposed inside the second outer ring head 3b. The second outer ring head 3b is threadedly connected to the top of the second outer ring base 1b to clamp and fix the second magnet 2b. At least two groups of equally spaced fastener insertion holes are provided on the outer surface of the second outer ring base 1b for inserting fasteners such as bolts and rivets to fix it on the ceiling. The outer surface of the second outer ring base 1b is also provided with evenly distributed plaster penetration holes, and the shape and size of the plaster penetration holes can be determined according to actual requirements. The purpose is that when using high-strength gypsum powder for embedded plastering, it can not only increase the contact area with the gypsum powder but also enable the high-strength gypsum powder to pass through the plaster penetration holes and adhere to the ceiling, effectively improving the firmness of the embedding. The usage is generally the same as that in the first embodiment, and no more details will be described here. The only difference is the installation steps between the outer ring component and the ceiling. One is through the clamping of the spring buckle 4, and the other is through the adhesive embedding of high-strength gypsum powder, both of which are common existing installation methods.

[0040] It should be specifically noted here that Figures 7 - 11 Shown are light-shielding discs 8 of various shapes, such as a hollow frustum, a hollow frustum with an inclined top surface, a disc with an eccentric ellipse, etc. The light-shielding discs 8 of the above shapes are applicable in both the first embodiment and the second embodiment and can be replaced according to the actual irradiation requirements of the downlight.

[0041] In addition, the light-shielding disc 8 includes but is not limited to Figures 7 - 11 the shapes shown.

[0042] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
