Description

Technical Field

[0001] The utility model relates to a lighting device, in particular to a downlight with adjustable installation size. Background Art

[0002] Downlights are a common lighting fixture, widely used in indoor environments such as homes, offices, and shopping malls. They are typically installed on the ceiling or within conduit or electrical equipment boxes (UL tubes) that meet the safety standards of Underwriters Laboratories Inc. (UL tubes). The installation location of downlights varies by region: in China and Europe, downlights are typically mounted on the ceiling; in the United States, they are more likely to be installed within UL tubes.

[0003] The traditional downlight structure generally includes the following main parts: the lamp body shell, which is the main part of the downlight and is used to accommodate and protect the internal components; the LED light source board, which is installed in the lamp body shell and is responsible for providing the lighting source; the reflector cup, which is installed on the LED light source board and is used to reflect light and enhance the lighting effect; the light cover, which is installed on the open end of the lamp body shell, protects the light source and ensures that the light is softly spread; the driving power supply, which is installed on the back of the lamp body shell or in the driving box, provides a stable power supply for the LED light source board; the spring connector, which is fixedly installed on the back of the lamp body shell or on the mounting base, is used for fixed installation of the downlight.

[0004] Traditional downlight designs have several limitations, particularly spring-loaded connectors, which are typically fixed to the back of the housing or mounting base, preventing position adjustment. This fixed connection restricts downlight installation flexibility, as it can fail to fit if the downlight's dimensions don't match the ceiling opening or UL tube dimensions, limiting its versatility and applicability in various installation environments. Summary of the Invention

[0005] The technical problem to be solved by the utility model is to provide a downlight with adjustable installation size, which can adjust the installation size to match UL tubes of different sizes, can adapt to installation environments of different sizes, and improve installation compatibility.

[0006] The technical solution adopted by the present invention to solve the above-mentioned technical problems is: a downlight with adjustable installation size, including a lamp body, two mounting seats, and two spring connectors, the lamp body including an outer shell, and the two mounting seats are symmetrically distributed on the back of the outer shell, characterized in that: the spring connectors and the corresponding mounting seats are connected by an adjustment mechanism that can adjust the connection position of the spring connectors on the mounting seats, thereby realizing the adjustment of the installation size of the downlight.

[0007] The mounting base comprises a first mounting component, the spring connector comprises a second mounting component and a spring mounted on the second mounting component, the adjustment mechanism comprises a vertical mounting post provided on the first mounting component, an elongated adjustment hole provided on the second mounting component, and a fastener for connecting to the vertical mounting post. The axial direction of the vertical mounting post is aligned with the axial direction of the lamp body, and the length direction of the elongated adjustment hole is aligned with the radial direction of the lamp body. The vertical mounting post is embedded in the elongated adjustment hole, and the first and second mounting components are integrally connected by the fastener. The second mounting component is constrained between the first mounting component and the head of the fastener, and the second mounting component can move radially on the first mounting component along the lamp body to adjust the distance between the spring connector and the housing. In this structure, the cooperation between the vertical mounting post and the elongated adjustment hole enables the second mounting component to move radially on the first mounting component along the lamp body, thereby adjusting the distance between the spring connector and the housing and achieving adjustment of the downlight installation size. The second mounting component is constrained in the axial direction of the lamp body by the fastener.

[0008] The first mounting component is provided with a plurality of elastic components on both sides, and the elastic components on both sides are symmetrically distributed. The second mounting component is provided with a plurality of clamping components on both sides, and the clamping components on both sides are symmetrically distributed. The second mounting component is moved radially along the lamp body so that the clamping components engage with elastic components at different positions relative to the housing, thereby changing the distance between the spring connector and the housing. In this structure, when the spring connector moves to a suitable position relative to the housing, the clamping components can engage with the elastic components, limiting the position of the spring connector, thereby changing the installation size of the downlight and improving the compatibility and installation flexibility of the downlight. The symmetrical arrangement of the elastic components and clamping components provides uniform support and limiting, ensuring the stable clamping of the spring connector at different positions.

[0009] The inner side of the elastic component is designed as an inwardly convex curved surface, and the engaging component is an arc-shaped notch that matches the inwardly convex curved surface. In this structure, the design of the inwardly convex curved surface and the arc-shaped notch provides self-alignment and a smooth engaging action, making the installation and adjustment process smoother and improving the user experience.

[0010] The height of the vertical mounting post is higher than the depth of the elongated adjustment hole. In this structure, in actual design, the height of the vertical mounting post is slightly higher than the depth of the elongated adjustment hole. This design allows the second mounting component to move stably horizontally on the first mounting component.

[0011] An extension column extends downward from the vertical mounting post, located below the first mounting component. A reinforcing rib is provided between the sidewall of the extension column and the bottom end surface of the first mounting component. The inner surface of the rib is designed to match the peripheral wall of the outer shell and conforms to the inner surface of the rib. In this structure, the extension column provides additional support and stability, which can be used to support heavier downlights or provide additional fixing under specific installation conditions. The provision of the reinforcing rib, and the conformation of the inner surface of the rib with the peripheral wall of the outer shell, enhance the mechanical strength of the extension column and the first mounting component, including rigidity and bending resistance, thereby improving the durability and reliability of the entire downlight.

[0012] The outer diameter of the vertical mounting post matches the width of the elongated adjustment hole, preventing the post from moving in the width direction of the elongated adjustment hole. In this structure, the outer diameter of the vertical mounting post matches the width of the elongated adjustment hole, providing precise positioning and restraint, preventing unnecessary lateral movement, and ensuring the structural stability of the downlight.

[0013] The first mounting component is a horizontal mounting component, and the second mounting component is an L-shaped mounting component. The elongated adjustment hole is formed in the horizontal section of the second mounting component, and the clamping component is provided on the horizontal section of the second mounting component. The spring comprises a plurality of spring coils and spring arms extending outward from both ends of the spring coils. The spring coils are connected to the vertical section of the second mounting component by a clamping mechanism. In this structure, the second mounting component is designed as an L-shaped structure, and the spring coils are connected to the vertical section of the second mounting component, making the overall structure of the spring connector more compact and reducing the overall size of the downlight. The clamping mechanism for the spring coils and the vertical section of the second mounting component can adopt any existing well-established clamping mechanism, such as providing a barbed buckle on the vertical section of the second mounting component, in which the spring coils are clamped. Due to the strong elastic force of the spring coils, the spring coils and the barbed buckle are not easily disengaged. Alternatively, baffles provided on both sides of the vertical section of the second mounting component can further prevent the spring coils from disengaging from the barbed buckle, and the baffles also serve to reinforce the vertical section of the second mounting component.

[0014] The lamp body also includes an LED light source board, a light-transmitting cover, a driving power supply, and a driving box. The LED light source board is installed in the shell, the light-transmitting cover is installed on the open end of the shell, the driving power supply is installed in the driving box, and the driving box is installed on the back of the shell. The two mounting seats are symmetrically installed on the peripheral wall of the shell or on the side wall of the driving box and close to the peripheral wall of the shell. In this structure, a screw hole column is provided in the driving box, and corresponding screw holes are provided on the bottom of the lamp body and the LED light source board. The LED light source board, the lamp body, and the driving box are connected by screws. The mounting seat can be directly provided on the peripheral wall of the shell, or on both sides of the driving box. When the mounting seat is directly provided on the peripheral wall of the shell, the mounting seat can be fixed to the peripheral wall of the shell by screws or snaps. When the mounting seat is provided on the side wall of the driving box, the mounting seat is fixed to the shell through the driving box.

[0015] Compared with the prior art, the advantages of the present invention are:

[0016] The connection position of the spring connector on the mounting base can be adjusted through the adjustment mechanism, allowing the downlight to adapt to installation spaces of different sizes, that is, it can match UL tubes of different sizes, thereby improving the installation compatibility of the downlight and thus improving the versatility and market adaptability of the downlight.

[0025] The present invention will be described in further detail below with reference to the accompanying drawings and embodiments.

[0026] The present invention proposes a downlight with adjustable installation dimensions, as shown in the figure. The downlight comprises a lamp body 1, two mounting bases 2, and two spring connectors 3. The lamp body 1 includes a housing 11, and the two mounting bases 2 are symmetrically located on the back of the housing 11. The spring connectors 3 are connected to the corresponding mounting bases 2 via an adjustment mechanism 4 that can adjust the connection position of the spring connectors 3 on the mounting bases 2, thereby achieving adjustment of the downlight's installation dimensions. In this structure, the adjustment mechanism 4 enables adjustment of the connection position of the spring connectors 3 on the mounting bases 2, allowing the downlight to adapt to installation spaces of varying sizes, i.e., to match UL downlights of varying sizes. This improves the downlight's installation compatibility, thereby enhancing its versatility and market adaptability.

[0027] It is further defined that the mounting base 2 is composed of a first mounting component 21, the spring connector 3 is composed of a second mounting component 31 and a spring 32 installed on the second mounting component 31, the adjustment mechanism 4 includes a vertical mounting column 41 arranged on the first mounting component 21 and an elongated adjustment hole 42 opened on the second mounting component 31, and a fastener 43 for connecting to the vertical mounting column 41, the axial direction of the vertical mounting column 41 is consistent with the axial direction of the lamp body 1, the length direction of the elongated adjustment hole 42 is consistent with the radial direction of the lamp body 1, the vertical mounting column 41 is embedded in the elongated adjustment hole 42 and the first mounting component 21 and the second mounting component 31 are connected into one through the fastener 43, the second mounting component 31 is limited between the first mounting component 21 and the head 431 of the fastener 43, and the second mounting component 31 can move along the radial direction of the lamp body 1 on the first mounting component 21 to adjust the distance between the spring connector 3 and the shell 11. In this structure, through the cooperation of the vertical mounting column 41 and the elongated adjustment hole 42, the second mounting component 31 can move radially along the lamp body 1 on the first mounting component 21, thereby adjusting the distance between the spring connector 3 and the outer shell 11 and achieving the adjustment of the downlight installation size; the second mounting component 31 is limited in the axial direction of the lamp body 1 by the fastener 43.

[0028] It is further defined that a plurality of elastic components 22 are provided on both sides of the first mounting component 21, and the elastic components 22 on both sides are symmetrically distributed. A plurality of clamping components 33 are provided on both sides of the second mounting component 31, and the clamping components 33 on both sides are symmetrically distributed. The second mounting component 31 is moved radially along the lamp body 1 so that the clamping components 33 engage with the elastic components 22 at different positions away from the housing 11, thereby changing the distance between the spring connector 3 and the housing 11. In this structure, when the spring connector 3 moves to a suitable position away from the housing 11, the clamping components 33 can engage with the elastic components 22, limiting the position of the spring connector 3, thereby changing the installation size of the downlight and improving the compatibility and installation flexibility of the downlight. The symmetrically arranged elastic components 22 and clamping components 33 provide uniform support and limiting, ensuring the stable clamping of the spring connector 3 at different positions.

[0029] In a preferred embodiment, the inner side of the elastic member 22 is designed as an inwardly convex curved surface, and the engaging member 33 is a curved notch that matches the inwardly convex curved surface. In this structure, the design of the inwardly convex curved surface and the curved notch provides self-alignment and a smooth engaging action, making the installation and adjustment process smoother and improving the user experience.

[0030] Furthermore, the height of the vertical mounting post 41 is greater than the depth of the elongated adjustment hole 42. In this structure, in actual design, the height of the vertical mounting post 41 can be slightly greater than the depth of the elongated adjustment hole 42. This design allows the second mounting member 31 to move stably horizontally on the first mounting member 21.

[0031] In a preferred embodiment, an extension column 44 is provided downwardly extending from the vertical mounting column 41. The extension column 44 is located below the first mounting component 21. A reinforcing rib 5 is provided between the sidewall of the extension column 44 and the bottom end surface of the first mounting component 21. The inner side surface of the reinforcing rib 5 is designed to be compatible with the peripheral wall of the outer shell 11 and is in close contact with the peripheral wall of the outer shell 11. In this structure, the provision of the extension column 44 provides additional support and stability, which can be used to support heavier downlights or provide additional fixing under specific installation conditions. The provision of the reinforcing rib 5, and the contact between the inner side surface of the reinforcing rib 5 and the peripheral wall of the outer shell 11, enhance the mechanical strength of the extension column 44 and the first mounting component 21, including rigidity and bending resistance, thereby improving the durability and reliability of the entire downlight.

[0032] In a preferred embodiment, the outer diameter of the vertical mounting post 41 matches the width of the elongated adjustment hole 42, restricting the vertical mounting post 41 from swaying in the width direction of the elongated adjustment hole 42. In this structure, the outer diameter of the vertical mounting post 41 matches the width of the elongated adjustment hole 42, providing precise positioning and restriction, preventing unnecessary lateral movement, and ensuring the structural stability of the downlight.

[0033] It is further defined that the first mounting component 21 is a horizontal mounting component, the second mounting component 31 is an L-shaped mounting component, the elongated adjustment hole 42 is opened on the horizontal section 311 of the second mounting component 31, the clamping component 33 is arranged on the horizontal section 311 of the second mounting component 31, and the spring 32 includes a plurality of spring coils 321 and spring arms 322 extending outward from both ends of the spring coils 321, and the spring coils 321 are connected to the vertical section 312 of the second mounting component 31 by a clamping manner. In this structure, the second mounting component 31 is designed as an L-shaped structure, and the spring coil 321 of the spring 32 is connected to the vertical section 312 of the second mounting component 31, so that the overall structure of the spring connector 3 is more compact and the overall size of the downlight is reduced; the clamping method of the spring coil 321 and the vertical section 312 of the second mounting component 31 can adopt any existing mature clamping structure, such as providing a barbed buckle 34 on the vertical section 312 of the second mounting component 31, and the spring coil 321 is clamped in the barbed buckle 34. Since the elastic force of the spring coil 321 is very large, the spring coil 321 and the barbed buckle 34 are not easy to disengage. The baffles 35 provided on both sides of the vertical section 312 of the second mounting component 31 can also further prevent the spring coil 321 from escaping from the barbed buckle 34. The baffles 35 also have the function of strengthening the vertical section 312 of the second mounting component 31.

[0034] It is further defined that the lamp body 1 also includes an LED light source board 12, a light-transmitting cover 13, a driving power supply 14 and a driving box 15. The LED light source board 12 is installed in the outer shell 11, the light-transmitting cover 13 is installed on the open end of the outer shell 11, the driving power supply 14 is installed in the driving box 15, and the driving box 15 is installed on the back of the outer shell 11. The two mounting seats 2 are symmetrically installed on the peripheral wall of the outer shell 11 or on the side wall of the driving box 15 and close to the peripheral wall of the outer shell 11. In this structure, a screw hole column is provided in the driving box 15, and corresponding screw holes are provided on the bottom of the lamp body 1 and the LED light source board 12. The LED light source board 12, the lamp body 1, and the driving box 15 are connected by screws; the mounting seat 2 can be directly set on the peripheral wall of the outer shell 11, or it can be set on both sides of the driving box 15. When the mounting seat 2 is directly set on the peripheral wall of the outer shell 11, the mounting seat 2 can be fixed to the peripheral wall of the outer shell 11 by screws or snaps. When the mounting seat 2 is set on the side wall of the driving box 15, the mounting seat 2 is fixedly installed on the outer shell 11 through the driving box 15.

[0035] When the downlight is installed, if the UL downlight is small, the second mounting member 31 is moved on the first mounting member 21 toward the lamp body 1, so that the clamping members 33 on both sides of the second mounting member 31 are clamped with the elastic members 22 on both sides of the first mounting member 21 closer to the lamp body 1. Figure 1When the UL tube size is large, the second mounting member 31 moves on the first mounting member 21 toward the side away from the lamp body 1, so that the clamping members 33 on both sides of the second mounting member 31 are clamped with the elastic members 22 on both sides of the first mounting member 21 at a position farther away from the lamp body 1, as shown. Figure 2 As shown, in this way, the installation size of the downlight can be changed, and it can be adapted to openings or UL tubes of different sizes to achieve compatibility.
