Description

Technical Field

[0001] The utility model belongs to the technical field of lighting fixtures, and in particular relates to a downlight housing with a magnetic flange. Background Art

[0002] A downlight is a fixture with a screw-on base that can be directly installed with an incandescent or energy-saving lamp. It is a downlight that is embedded in the ceiling and projects light downward. Its greatest advantage is that it maintains the overall unity and perfection of the building's decoration, without disrupting the effect of the suspended ceiling. This recessed fixture, embedded in the ceiling, projects all light downward, using direct light distribution. Different reflectors, lenses, and bulbs can be used to achieve different lighting effects.

[0003] Downlights are typically installed using a recessed design. After installation, only the flange at the bottom of the housing remains exposed to the ceiling. A suitably colored flange can complement the ceiling, creating a more decorative effect. However, traditional downlight housings are often die-cast, forming a single piece. Replacing the flange requires replacing the entire housing, or even the entire downlight itself, making assembly and disassembly cumbersome and costly. Furthermore, traditional downlights lack the ability to adjust mounting height and lighting angle, making them less adaptable. Therefore, there is an urgent need to design a downlight housing with a magnetic flange to address these issues. Utility Model Content

[0031] Example 1:

[0032] The utility model provides Figure 1-9 A downlight housing with a magnetic flange as shown in the figure comprises:

[0033] The mounting base 100 has a groove 101 at the bottom thereof, a magnetic block 102 is fixedly nested in the groove 101, a flange 103 is provided at the bottom of the mounting base 100 and is fixed by the magnetic block 102, and an annular groove 104 is provided at the top of the mounting base 100;

[0034] The connecting base 200 is arranged on the top of the mounting base 100, and the outer edge of the connecting base 200 is embedded in the annular groove 104. The connecting base 200 and the mounting base 100 are fixedly connected by a limit bar 105. The inner wall of the connecting base 200 is provided with a connecting column 201, the top of the connecting base 200 is provided with a stopper 202, and the inner top surface of the connecting base 200 is provided with a scale 203;

[0035] The radiator 300 is arranged on the top of the connecting base 200. The inner bottom of the radiator 300 is provided with a screw hole 301 and a rotating handle 302. The radiator 300 is fixedly connected to the connecting base 200 by bolts.

[0036] For example, see Figure 8 As shown, there are at least four magnetic blocks 102 , and the four magnetic blocks 102 are equidistantly arranged around the bottom of the mounting base 100 .

[0037] In this technical solution, the four magnetic blocks 102 can provide sufficient and uniform adsorption force for the flange 103, ensuring that the flange 103 and the mounting base 100 can be firmly adsorbed, which is beneficial to improving the stability of the structure. At the same time, the magnetic fixed connection method is also easier to disassemble and assemble, and disassembling and replacing the flange 103 separately can greatly reduce maintenance costs.

[0038] For example, see Figure 1-2As shown, there are two limit bars 105, both of which are arc-shaped structures with the same curvature. The limit bars 105 are fixed to the top of the mounting base 100 by bolts, and one side of the limit bar 105 extends to the top of the outer edge of the connecting seat 200.

[0039] In this technical solution, the limiting strip 105 is fixedly connected to the mounting base 100 as a whole. The limiting strip 105 can limit the outer edge of the connecting seat 200 in the annular groove 104, so that the mounting base 100 and the connecting seat 200 can be connected, and the connection is stable and convenient for disassembly and assembly.

[0040] For example, see Figure 1-2 and Figure 7-8 As shown, at least four locking members 106 are fixed to the inner side of the mounting base 100 by bolts. The four locking members 106 are arranged equidistantly around the bottom of the locking members 106. A support plate 1061 is fixed to the bottom of the mounting base 100 in the horizontal direction. The support plate 1061 is in contact with the bottom of the mounting base 100 and extends to the outside of the mounting base 100.

[0041] In this technical solution, the four support plates 1061 are first fitted with the lower surface of the ceiling. Since the four locking members 106 are equidistantly arranged around the inner side surface of the mounting base 100, the four support plates 1061 are equidistantly arranged around the outer edge of the mounting base 100, thereby making the contact points between the mounting base 100 and the lower surface of the ceiling more evenly distributed, which is conducive to more stable installation of the mounting base 100. The support plates 1061 are fitted with the bottom of the mounting base 100, which can shorten the distance between the mounting base 100 and the lower surface of the ceiling as much as possible, which is conducive to improving the installation effect.

[0042] For example, see Figure 1-2 and Figure 5-6 As shown, two rectangular grooves 107 are provided on the outer side of the mounting base 100. The two rectangular grooves 107 are respectively arranged between the ends of the two limiting strips 105. A mounting bracket 108 is provided in the rectangular groove 107. The mounting bracket 108 is connected to the mounting base 100 by an adjusting bolt 109.

[0043] In this technical solution, the adjusting bolt 109 is threadedly connected to the mounting bracket 108. By rotating the adjusting bolt 109, the position of the mounting bracket 108 on the adjusting bolt 109 can be adjusted, thereby realizing height adjustment of the mounting bracket 108, so that the distance between the bottom of the mounting bracket 108 and the top of the support plate 1061 can be adjusted, and the mounting base 100 can be firmly fixed on ceilings of different thicknesses.

[0044] For example, see Figure 8 As shown, the mounting base 100 and the connecting column 201 are fixedly connected by bolts.

[0045] The technical scheme is favorable to further improve the stability of the connection between the mounting base 100 and the connecting seat 200.

[0046] Exemplarily, referring to Figure 5-6 As shown in the figure, the upper surface of the connecting seat 200 and the lower surface of the heat sink 300 are both inclined surfaces, and the inclination angles are the same.

[0047] In the technical scheme, when the lowest point of the upper surface of the connecting seat 200 coincides with the lowest point of the lower surface of the heat sink 300, the heat sink 300 and the light source module mounted inside the heat sink 300 can keep a horizontal state, at this time, the light vertically irradiates downward; when it is needed to adjust the irradiation angle of the light, first, the bolt used for connecting the heat sink 300 and the connecting seat 200 is removed, then the rotating handle 302 is held and pulled to make the heat sink 300 relatively rotate with the connecting seat 200, when the rotating handle 302 is rotated to a specified value on the scale 203, the heat sink 300 and the connecting seat 200 are fixedly connected through the bolt again, at this time, the heat sink 300 is inclined, and the irradiation angle of the light is changed according to the set value.

[0048] Exemplarily, referring to Figure 1 and Figure 3-6 As shown in the figure, the outer surface of the heat sink 300 is fixed with a plurality of fins in the vertical direction, and the bottom end of each fin on the two sides of the heat sink 300 is lower than the height of the stop block 202.

[0049] In the technical scheme, the stop block 202 at the top of the connecting seat 200 can block and limit the two fins, so that the rotation of the heat sink 300 can be limited in a certain range, and it is convenient and fast to return to the initial position.

[0050] Embodiment 2:

[0051] The utility model provides a down lamp lamp house with magnetic formula flange disc as Figure 10 The difference between the embodiment 2 and the embodiment 1 is that the cross section of the mounting base 100 is a rectangular frame structure, which is suitable for the scene that the reserved hole of the ceiling down lamp is rectangular.

[0052] Working principle: When using the downlight housing with a magnetic flange, first align the mounting base 100 with the downlight reserved hole on the ceiling, and then push the mounting base 100 upwards until the support plate 1061 is in contact with the bottom surface of the ceiling. At this time, open the mounting bracket 108, and then turn the adjusting bolt 109 to adjust the height of the mounting bracket 108 until the mounting base 100 is clamped and fixed to the ceiling by the mounting bracket 108 and the support plate 1061. When the flange 103 needs to be replaced, simply remove the flange 103 and adsorb the new flange 103 on the bottom of the mounting base 100. When the angle of the light needs to be adjusted, remove the connecting bolts between the connecting base 200 and the radiator 300, and then drive the radiator 300 to rotate by turning the handle 302. At this time, the radiator 300 is tilted at a specific angle, and then the connecting base 200 and the radiator 300 are fixedly connected by bolts. The downlight housing with a magnetic flange has an advanced design, a compact structure, and is easy to use. The mounting base 100 and the flange 103 adopt a split structural design. Depending on the color of the ceiling, only the flange 103 of a different color can be replaced, which greatly reduces the cost. By providing a magnetic block 102 at the bottom of the mounting base 100, the mounting base 100 and the flange 103 are fixed by magnetic attraction, which is convenient for disassembly and replacement. By providing a connecting seat 200 and a radiator 300 with an inclined surface, the inclination angle of the light source in the radiator 300 can be adjusted by rotating the radiator 300, and the installation height of the mounting base 100 can be adjusted by rotating the adjusting bolt 109, which greatly enhances the applicability of the downlight housing with a magnetic flange.

[0053] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
