Description

Technical Field

[0001] This invention relates to the field of lighting fixtures, specifically to a downlight mounting structure. Background Technology

[0002] In addition to conventional lighting applications, LED downlights can also be optically adjusted to focus light onto a specific area, thereby highlighting the corresponding product or scene. This leads to the development of corresponding LED spotlights and ambient lighting products. Ordinary LED downlights are mostly fixed projections, while LED spotlights require consideration of the illumination angle and range during installation for different applications.

[0003] Common downlights are mainly used in suspended ceiling structures. Mounting holes are cut into the ceiling surface, and the downlights are inserted into these holes and fixed to the ceiling with screws. Existing downlight structures typically have spring-loaded fins on both sides, which press against the inner surface of the ceiling to secure the downlight to the mounting holes. However, the load-bearing capacity of the spring-loaded fins is limited, and variations in ceiling thickness and load-bearing capacity can restrict the installation of the downlights. Furthermore, the weight of the downlight itself can affect its stability after installation. Downlights fixed with screws require pre-drilled screw holes in the ceiling, making installation and removal inconvenient and time-consuming.

[0004] In particular, the installation of existing adjustable-angle downlights / spotlights requires space to be reserved in the upper part of the ceiling to ensure the movement of the downlights. This installation method is difficult to adapt to different ceiling sizes, thus limiting the application range of the downlights. Therefore, existing technology needs further improvement and development. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings and deficiencies of existing technologies by providing a downlight mounting structure that is structurally sound, easy to assemble and disassemble, has high heat dissipation efficiency, and is flexible in application.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] The present invention discloses a downlight mounting structure, comprising a substrate and a heat sink, wherein the substrate has an assembly hole; it also includes an insertion module and a guide structure, wherein the insertion module is provided on the inner edge of the assembly hole and is fixedly connected to the substrate; the heat sink has a guide structure, which is arranged around the outer edge of the heat sink; when the heat sink is inserted into the assembly hole, the guide structure is paired with the insertion module, thereby allowing the heat sink to be movably mounted on the substrate, and an adjustable-angle LED module is provided inside the heat sink.

[0008] According to the above scheme, the import module includes a guide slider, which is disposed on the inner edge of the assembly hole and is fixedly connected to the substrate. The guide slider is provided with an import ramp with a spiral feature. The guide structure includes a lifting slide plate with a spiral feature, which is disposed around the outer edge of the heat sink. The lifting slide plate is movably disposed on the import ramp so that the heat sink can rotate horizontally within the assembly hole to achieve lifting motion. An anti-slip component is provided between the lifting slide plate and the guide slider.

[0009] According to the above scheme, the anti-slip component includes a beam frame, a pressure block, and an elastic plunger. The outer side of the guide slider is provided with a beam frame, and the lower end of the beam frame is fixedly connected to the base plate. The outer bottom end of the pressure block is fixedly connected to the upper end of the beam frame, so that the inner bottom end of the pressure block is positioned above the guide slope. The inner bottom end of the pressure block is engaged with the upper end of the elastic plunger. When the heat dissipation cylinder is inserted into the assembly hole, the lower end of the elastic plunger presses against the upper surface of the lifting slide plate, thereby fixing it on the guide slider.

[0010] According to the above scheme, the lower surface of the lifting slide plate and the guide slider's inlet slope form a sliding fit. The upper surface of the lifting slide plate is provided with anti-slip texture, and the lower end of the elastic plunger presses against the anti-slip texture, thereby connecting the lifting slide plate and the guide slider.

[0011] According to the above scheme, the LED module includes a first module, a second module, an LED light source, and a lens. A base plate is provided on the upper port of the heat sink. The first module passes through the heat sink and is rotatably connected to the base plate. The second module is located below the first module and is connected to the first module through a swing structure. The LED light source is fixedly mounted on the second module, and the lens is mounted on the LED light source and fixedly connected to the second module.

[0012] According to the above scheme, the lower end of the first module has a concave spherical surface, the second module is movably disposed in the concave spherical surface, a sliding groove is provided on the concave spherical surface, a sliding post is provided at the upper end of the second module, the sliding post passes through the sliding groove, and a locking nut is provided at the upper end of the sliding post.

[0013] According to the above scheme, the upper end of the first module is provided with a hollow threading bushing, the bottom plate is provided with a through hole and the threading bushing is rotatably inserted through the through hole, and the upper end of the threading bushing is provided with a limiting nut and an elastic element.

[0014] According to the above scheme, a stop ring is provided on the lower end of the heat sink, and the stop ring is fixedly connected to the heat sink. The outer diameter of the stop ring is larger than the outer diameter of the heat sink. A light-transmitting panel is provided in the inner hole of the stop ring, and the light-transmitting panel is detachably connected to the stop ring.

[0015] According to the above scheme, the base plate is provided with several heat sinks.

[0016] The beneficial effects of this invention are as follows: The invention has a reasonable structure. The lifting slide plate and the guide module work together to allow the heat sink to be installed into the assembly hole in a spiral manner. The substrate can be fixed on the ceiling as a modular structure, which has higher load-bearing strength and can meet the installation requirements of high-power downlights. It is also more convenient to disassemble and assemble. The heat sink can conduct heat to the substrate through the guide slider. Combined with the heat dissipation area of ​​the heat sink itself, it can effectively improve the heat dissipation efficiency of the LED light source. When the LED light source is adjusted horizontally, the heat sink does not need to rotate, thus avoiding the problem of wire entanglement. Attached Figure Description

[0023] The technical solution of the present invention will be described below with reference to the accompanying drawings and embodiments.

[0024] like Figure 1-4As shown, the present invention discloses a downlight mounting structure, comprising a base plate 1 and a heat sink 2. The base plate 1 has an assembly hole 11 and can adopt a rectangular modular structure for easy installation on existing integrated ceilings. The base plate 1 has a large area to support the overall weight of the downlight. It also includes an insertion module 3 and a guiding structure. The insertion module 3 is located on the inner edge of the assembly hole 11 and is fixedly connected to the base plate 1. The heat sink 2 has a guiding structure surrounding its outer edge. When the heat sink 2 is inserted into the assembly hole 11, the guiding structure and the insertion module 3 are paired and connected, allowing the heat sink 2 to be movably mounted on the base plate 1. The heat sink 2 contains an adjustable-angle LED module 4. The guiding structure and the insertion module 3 cooperate to allow the heat sink 2 to be screwed into the assembly hole 11 and fixed to the base plate 1, making disassembly and installation more convenient. Furthermore, the heat sink 2 can be rotated within the assembly hole 11 to adjust its mounting height on the base plate 1, thus adapting the downlight to ceilings of different heights and expanding its application range.

[0025] The inlet module 3 includes a guide slider 31, which is disposed on the inner edge of the mounting hole 11 and fixedly connected to the base plate 1. The guide slider 31 has an inlet ramp 32 with a spiral feature. The guiding structure includes a lifting slide plate 21 with a spiral feature, which is disposed around the outer edge of the heat sink 2. The lifting slide plate 21 is movably disposed on the inlet ramp 32, allowing the heat sink 2 to rotate horizontally within the mounting hole 11 to achieve lifting motion. An anti-slip component is provided between the lifting slide plate 21 and the guide slider 31. When the heat sink 2 rotates within the mounting hole 11, the lifting slide plate 21 can slide along the inlet ramp 32 on the guide slider 31. Since both the lifting slide plate 21 and the inlet ramp 32 have spiral features, the horizontal rotation of the heat sink 2 is converted into vertical displacement, thereby allowing the heat sink 2 to be installed into the mounting hole. After installation, the anti-slip component locks the lifting slide plate 21 and the guide slider 31, thereby fixing the downlight to the base plate 11.

[0026] The anti-slip assembly includes a beam frame 33, a pressure block 34, and an elastic plunger 35. The beam frame 33 is provided on the outer side of the guide slider 31, and the lower end of the beam frame 33 is fixedly connected to the base plate 1. The outer bottom end of the pressure block 34 is fixedly connected to the upper end of the beam frame 33, so that the inner bottom end of the pressure block 34 is positioned above the guide slope 32. The inner bottom end of the pressure block 34 is connected to the upper end of the elastic plunger 35. The specific connection method can be screw fixing, so that there is an elastic gap between the lower end of the elastic plunger 35 and the guide slope 32. When the heat dissipation cylinder 2 passes through the assembly hole 11, the lower end of the elastic plunger 35 presses against the upper surface of the lifting slide plate 21, so that it is fixedly mounted on the guide slider 31. The bottom surface of the lifting slide plate 21 and the guide slope 32 are both smooth surfaces. The lifting slide plate 21 passes between the guide slope 32 and the lower end of the elastic plunger 35. The elastic plunger 35 exerts an elastic force on the lifting slide plate 21 pointing towards the guide slope 32. Thus, with a small torque, the heat sink 2 can be driven to overcome the frictional resistance between the lifting slide plate 21 and the guide slope 32, allowing the lifting slide plate 21 to slide along the guide slope 32 on the guide slider 31. The heat sink 2 rotates horizontally on the mounting hole 11, thereby realizing the assembly and disassembly of the downlight on the substrate 1. After the heat sink 2 is inserted into the mounting hole 11, the lower end of the elastic plunger 35 presses against the lifting slide plate 21 and applies an elastic force to it, so that sufficient frictional resistance is generated between the lifting slide plate 21 and the guide slope 32 to prevent the downlight from sliding out of the mounting hole 11 under its own weight.

[0027] The lower surface of the lifting slide plate 21 and the guide slope 32 of the guide slider 31 form a sliding fit. The upper surface of the lifting slide plate 21 is provided with anti-slip texture 22. The lower end of the elastic plunger 35 presses against the anti-slip texture 22, thereby connecting the lifting slide plate 21 and the guide slider 31. The anti-slip texture 22 is used to increase the frictional resistance between the lower end of the elastic plunger and the lifting slide plate 21, preventing the downlight from sliding out of the mounting hole 11 under its own weight.

[0028] The LED module 4 includes a first module 41, a second module 42, an LED light source 43, and a lens 44. A base plate 23 is provided on the upper port of the heat sink 2. The first module 41 passes through the heat sink 2 and is rotatably connected to the base plate 23. The second module 42 is located below the first module 41 and is connected to the first module 41 via a swing structure. The LED light source 43 is fixedly mounted on the second module 42, and the lens 44 covers the LED light source 43 and is fixedly connected to the second module 42. The lower end of the second module 42 has a mounting surface, and the LED light source 43 is mounted on the mounting surface and fixedly connected to the second module 42. The second module 42 can swing laterally on the first module 41 to change the projection angle of the LED light source 43, while the first module 41 can rotate horizontally on the base plate 23 to change the projection point of the LED light source 43.

[0029] The lower end of the first module 41 has a concave spherical surface 45. The second module 42 is movably disposed within the concave spherical surface 45. A sliding groove 46 is formed on the concave spherical surface 45. A sliding post 47 is provided at the upper end of the second module 42, passing through the sliding groove 46. A locking nut 48 is provided at the upper end of the sliding post 47. The locking nut 48 connects the sliding post 47 and the second module 42 to the sliding groove 46. The sliding post 47 can move along the sliding groove 46, allowing the second module 42 to swing on the first module 41, thereby changing the projection angle of the LED light source 43.

[0030] The upper end of the first module 41 is provided with a hollow threading bushing 49. A through hole is opened on the bottom plate 23, and the threading bushing 49 is rotatably inserted through the through hole. The upper end of the threading bushing 49 is provided with a limiting nut 24 and an elastic element. The lower end of the threading bushing 49 has a notch to connect to the sliding groove 46. A wire is connected to the LED light source. The wire passes through the sliding groove 46, the threading bushing 49 and the upper end of the heat sink 2 in sequence and connects to the controller.

[0031] The assembly hole 11 is provided with three inlet modules 3, and the corresponding heat sink 2 is provided with three lifting slide plates 21. The helix angle of the lifting slide plate 21 is between 30° and 75°, and the preferred helix angle of the lifting slide plate 21 is 45°. Therefore, the maximum rotation stroke angle of the heat sink 2 is within 120°, and the rotation range of the heat sink 2 is small. The angle adjustment of the LED light source 43 is achieved by the first module 41 and the second module 42, which can effectively avoid the problem of wire entanglement on the LED module 4.

[0032] The lower port of the heat sink 2 is provided with a stop ring 25, which is fixedly connected to the heat sink 2. The outer diameter of the stop ring 25 is larger than the outer diameter of the heat sink 2. A light-transmitting panel 26 is provided in the inner hole of the stop ring 25, and the light-transmitting panel 26 is detachably connected to the stop ring 25. The stop ring 25 can be fixed to the lower port of the heat sink 2 by a threaded connection. The stop ring 25 can abut against the substrate 1 to limit the upward travel of the heat sink 2. Preferably, a snap-fit ​​structure is provided between the light-transmitting panel 26 and the stop ring 25. The light-transmitting panel 26 is detachably connected to the stop ring 25 through the snap-fit ​​structure. After the light-transmitting panel 26 is removed, the angle of the LED module 4 can be adjusted.

[0033] The base plate 23 is provided with a plurality of heat sinks 27. The heat sinks 27 are used to increase the surface area of ​​the heat sink 2 to improve the heat dissipation efficiency. Furthermore, the heat sink 2 can conduct heat to the substrate 1 through the guide slider 31. The substrate 1 can provide heat dissipation assistance to the heat sink 2, thereby ensuring the heat dissipation efficiency of the high-power downlight.
