Description
Technical Field
[0001] This utility model relates to the field of lighting fixtures, and in particular to a metal profile for lighting fixtures. Background Technology
[0002] Depending on the specific needs of different usage scenarios, various types of lighting fixtures are constantly being developed. For large open spaces, large flat-panel lighting fixtures are installed, such as flat-panel billiard lights in billiard halls. These fixtures mainly consist of a frame and multiple flat-panel lights. The frame typically includes a main frame formed by splicing four profiles and strip frames arranged horizontally or vertically within the main frame. The strip frames divide the space within the main frame into multiple mounting slots, and the flat-panel lights are installed in these slots, with the edges of the flat-panel lights resting on the edges of the mounting slots.
[0003] In existing technology, the main frame of billiard lamps uses long, strip-shaped profiles. To achieve external light emission from the main frame, these profiles typically employ a U-shaped structure with an outward-opening cross-section. A support platform for the flat panel lamp is located on the side facing the mounting groove. The external light source is installed within the profile, enabling side lighting of the main frame. The profile needs sufficient structural strength and stability to support multiple flat panel lamps. Therefore, existing profiles of this type usually require increased wall thickness. If the wall is too thin, deformation is likely, failing to meet the requirements for structural strength and stability. However, thicker profiles increase manufacturing costs and material consumption. Reducing the production cost of this type of profile is the technical problem this invention aims to solve. Utility Model Content
[0004] The main purpose of this utility model is to provide a metal profile for lighting fixtures that can reduce costs while meeting structural strength requirements.
[0005] This utility model proposes a metal profile for lighting fixtures, which is strip-shaped and is an integral profile with a closed-loop cross-section formed by bending a thin metal sheet along its length until the two sides of the thin metal sheet meet along its length. The manufacturing process is relatively simple and material consumption is reduced. The profile includes a rear portion, a front portion, and two side portions connecting the front and rear portions. The front portion is recessed rearward to form an inner reinforcing frame, and the inner wall surface of the inner reinforcing frame can be used to mount a light source.
[0006] The profile has a closed-loop structure. Compared to a U-shaped structure, because the front and rear sections support the side sections, and the side sections support the front and rear sections, it is less prone to deformation under pressure. In contrast, a thin-walled U-shaped structure is easily deformed by its sides being folded inwards or outwards. The front section is recessed rearward to form an inner reinforcing frame. This recessed design not only meets the requirements for mounting the light source on the profile but also shifts the profile's center of gravity rearward, making the structure more stable. Furthermore, the inner reinforcing frame corresponds to the side sections on both sides, further enhancing the structural strength of the side sections.
[0007] Thin metal sheets are bent into shapes through roll forming.
[0008] Preferably, the inner reinforcing frame includes inner support surfaces on both sides and an inner connecting surface for connecting the inner support surfaces on both sides. The inner connecting surface is located at the rear end of the inner support surfaces. The two inner support surfaces are inclined from back to front and outward to provide inner support for the lateral portions on both sides. The two inner support surfaces respectively inclinedly support the lateral portions on both sides, making the structure more stable.
[0009] Preferably, the front end of the inner support surface is connected to the front end of the side portion, and is laterally bent to form a groove for inserting a lampshade. The bottom of the groove abuts against the inner wall surface of the side portion, enhancing the structural strength of the front end of the side portion.
[0010] Preferably, the inner connecting surface is configured as a light source mounting surface for mounting a light source. The light source is mounted on the light source mounting surface, and the light emitted from the light source shines out from the lampshade to illuminate the lampshade.
[0011] Preferably, one of the side portions extends rearward and protrudes behind the rear portion, and folds back to connect with one side of the rear portion. The portion of the side portion protruding behind the rear portion forms a support platform for supporting the edge of the flat panel lamp.
[0012] Preferably, the thin metal sheet is connected on both sides along its length by a connecting structure.
[0013] Preferably, the thin metal sheet is bent on one side along its length to form a first hook, and on the other side along its length to form a second hook. The connecting structure consists of the first hook and the second hook. The two sides of the thin metal sheet along its length are connected by hooking the first hook and the second hook together. The connection operation is simple, does not require welding, and will not burn the paint layer on the surface of the profile, eliminating the need for repainting and further reducing production costs.
[0014] Preferably, the cross-sections of the first hook and the second hook are U-shaped. After the first hook and the second hook are hooked together, they are flattened in the thickness direction so that the first hook and the second hook are tightly hooked together.
[0015] Preferably, the metal sheet is an iron sheet.
[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0017] The metal profile used in this lamp has a closed-loop structure, which is less prone to deformation and more stable than a U-shaped structure. The front part is recessed to the rear to form an inner reinforcing frame, which shifts the center of gravity of the profile to the rear, making the structure more stable. The two sides of the inner reinforcing frame correspond to the side parts, further enhancing the structural strength of the side parts. The two inner support surfaces are inclined to support the two side parts, making the structure more stable. The bottom of the groove abuts against the inner wall of the side part, enhancing the structural strength of the front end of the side part. The connection operation is simple, requiring no welding, and will not burn the paint layer on the surface of the profile, eliminating the need for repainting. The manufacturing process is relatively simple, reducing material consumption and production costs. Attached Figure Description

[0024] The realization of the purpose, functional features and advantages of this utility model will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation
[0025] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals identify the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.
[0026] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs; the terminology used herein in the specification of the application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application; the terms "comprising" and "having," and any variations thereof, in the specification, claims, and foregoing drawings of this application are intended to cover non-exclusive inclusion. The terms "first," "second," etc., in the specification, claims, or foregoing drawings of this application are used to distinguish different objects, not to describe a particular order.
[0027] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.
[0028] like Figure 1 As shown, this utility model provides a metal profile for lighting fixtures. The profile 10 is strip-shaped and is an integral profile with a closed-loop cross-section formed by bending a thin metal sheet along its length until the two sides of the thin metal sheet meet along its length. In this embodiment, the profile is formed by rolling and bending a thin metal sheet, which is relatively simple in manufacturing process and reduces material consumption.
[0029] Reference Figure 2 The profile includes a rear section 11, a front section, and two opposite side sections 3 connecting the front and rear sections 11. The front section is recessed rearward to form an inner reinforcing frame 2. The profile has a closed-loop structure. Compared with a U-shaped structure, the side sections are supported between the front and rear sections, and the front and rear sections are supported between the two side sections, making it less prone to deformation under pressure. The recessed design of the front section to form the inner reinforcing frame not only meets the requirements for installing a light source on the profile but also shifts the profile's center of gravity rearward, making the structure more stable. Furthermore, the two sides of the inner reinforcing frame correspond to the side sections, further enhancing the structural strength of the side sections.
[0030] The inner reinforcing frame 2 includes inner support surfaces 21 located on both sides and inner connecting surfaces 22 for connecting the inner support surfaces 21 on both sides. The inner connecting surfaces 22 are located at the rear end of the inner support surfaces 21. The two inner support surfaces 21 are inclined from back to front and outward to provide inner support for the side portions 3 on both sides. This design enables the inner reinforcing frame 2 to effectively enhance the structural strength of the profile and prevent the profile from deforming during use.
[0031] The front end of the inner support surface 21 is connected to the front end of the side part 3, and is laterally bent to form a groove 23 for inserting the lampshade. The bottom of the groove 23 abuts against the inner wall surface of the side part 3 to enhance the structural strength of the front end of the side part.
[0032] In this embodiment, the inner connecting surface is set as a light source mounting surface for mounting a light source. The light source is installed on the light source mounting surface, and the light emitted from the light source shines out from the lampshade to illuminate the lampshade.
[0033] One side portion 3 extends rearward and protrudes behind the rear portion 1, then folds back to connect with one side of the rear portion 1. The portion of the side portion 3 protruding behind the rear portion 1 forms a support platform 31. The support platform 31 can be used to install other components of the light fixture or to support the light fixture, such as... Figure 5 As shown, one edge of the flat panel lamp is supported on the support platform 31.
[0034] The thin metal sheet is connected at both ends along its length by a connecting structure 11. Specifically, a first hook is formed by bending one end of the thin metal sheet along its length, and a second hook is formed by bending the other end of the thin metal sheet along its length. The connecting structure 11 consists of the first hook and the second hook, and the two ends of the thin metal sheet are connected by hooking each other along their length. This connection method simplifies the profile manufacturing process, eliminating the need for welding or other connectors, and reducing production costs.
[0035] The first and second hooks have U-shaped cross-sections. After the first and second hooks are interlocked, they are flattened in the thickness direction, making them tightly connected. This design makes the connection more secure, less prone to loosening, and improves the overall strength and service life of the profile.
[0036] In a preferred embodiment, the metal sheet is an iron sheet. Iron sheets have good strength and machinability, and are relatively low in cost, making them suitable for mass production.
[0037] like Figure 3 As shown, the main frame consists of four profiles (10) joined together, with the support platform (31) facing inwards towards the inside of the main frame to support the flat-shaped lamp. The light source mounting surface faces outwards towards the main frame to mount the light source, enabling side-emitting light.
[0038] like Figure 4 As shown, two horizontal beams 20 are placed inside the main frame to form a frame. The beams 20 divide the installation space inside the main frame into three installation slots for installing flat panel lamps.
[0039] like Figure 5 and Figure 6 The diagram shown is a schematic of a flat panel lamp 30 installed within a frame.
[0040] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit the scope of protection of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on these embodiments, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model. Although this utility model has been described in detail with reference to the above embodiments, those skilled in the art can still combine, add, delete, or otherwise adjust the features of the various embodiments of this utility model according to the circumstances without conflict or creative effort, thereby obtaining different technical solutions that do not fundamentally depart from the concept of this utility model.
