Description

Technical Field

[0001] This utility model relates to the field of lighting technology, and in particular to a lighting frame. Background Technology

[0002] Existing direct-emitting light fixtures typically consist of a reflector, a light panel mounted on the inner wall of the reflector, multiple LEDs mounted on the light panel, and a diffuser plate covering the LEDs. To ensure uniform light scattering and avoid uneven brightness or visible light spots from the LEDs, a certain light emission distance must be maintained between the LEDs and the diffuser plate.

[0003] However, the fixed light emission distance also results in a relatively large overall height of the luminaire, making it difficult to achieve a thin and light design. It is particularly unsuitable for applications requiring low installation height or recessed applications. The higher structural height also leads to an increase in the amount of luminaire materials used and an increase in overall weight, thus increasing manufacturing costs. Utility Model Content

[0004] In view of this, the present invention provides a lamp frame to solve the problem that the height of lamps in the prior art is difficult to achieve in a thin and light design, which makes them less adaptable to occasions requiring low installation height or embedded applications. The higher structural height also leads to an increase in the amount of lamp material used, an increase in overall weight, and an increase in manufacturing costs.

[0005] To achieve one or more of the above objectives or other objectives, this utility model proposes a lamp frame having four profiles connected end to end. The profiles are L-shaped and formed by bending sheet metal. The inner side of the lower half of the profile is bent to form a convex bulge. The convex bulge is used to support the edge of the diffuser plate so that the reflector can press the diffuser plate, causing the middle of the diffuser plate to bulge downward and pass over the inner side wall of the lower half of the profile.

[0006] Preferably, the sheet material includes an L-shaped first sheet body, one side of the first sheet body is bent inward to form a edging, the other side of the first sheet body is stacked and inserted into the inner side of the edging, the portion of the first sheet body located on the inner side of the middle part of the profile is bent to form a 7-shaped support plate, and the portion of the first sheet body located on the inner side of the lower half end of the profile is bent to form a convex bump.

[0007] Preferably, the edging is located at the upper or lower end of the profile.

[0008] Preferably, the portion of the first plate located on the outer side of the lower half of the profile is bent to form a stepped structure.

[0009] Preferably, the portion of the first plate located on the inner side of the upper half of the profile or on the inner side of the lower half of the profile is bent to form a corrugated plate.

[0010] Preferably, the board material includes an L-shaped second board and an L-shaped third board. The third board is placed close to the inside of the second board. Both sides of the second board are bent inward to form edging. The two sides of the third board are respectively stacked and inserted into the inside of the adjacent edging. The middle part of the third board is bent to form a 7-shaped support plate. The lower half of the third board is bent to form a convex shape.

[0011] Preferably, the lower half of the second plate near the middle is bent to form a stepped structure.

[0012] Preferably, the upper half of the second plate is bent to form a corrugated plate.

[0013] Preferably, the upper half of the third plate is bent to form a corrugated plate.

[0014] Preferably, the sheet material is a surface-treatment-free material.

[0015] Implementing the embodiments of this utility model will have the following beneficial effects:

[0016] After adopting the above-mentioned lamp frame, the diffuser plate is supported by the convex bulge, so that the open end of the reflector can press down on the periphery of the diffuser plate, causing the middle part of the diffuser plate to bulge down and extend beyond the inner wall of the lower half of the profile, or even beyond the lower half of the profile. While maintaining a fixed light emission distance between the lamp panel and the diffuser plate, the two are lowered as a whole, making use of the space at the lower opening of the lamp frame (equivalent to the thickness of the lower half of the profile). This reduces the space occupied by the thickness of the diffuser plate on the height of the lamp frame, so that the height of the profile or the lamp frame can be made smaller, achieving a thinner and lighter design of the lamp, improving the adaptability of the lamp in low installation height or recessed applications, reducing the amount of material used and the weight of the lamp, and reducing manufacturing costs.

[0032] 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 invention pertains; the terminology used herein in the specification is for the purpose of describing particular embodiments only and is not intended to limit the invention; the terms "comprising" and "having," and any variations thereof, in the specification, claims, and accompanying drawings of this invention are intended to cover non-exclusive inclusion. The terms "first," "second," etc., in the specification, claims, or accompanying drawings of this invention are used to distinguish different objects, not to describe a particular order. The term "inner side" in the specification, claims, or accompanying drawings of this invention refers to the side of the corresponding structure closer to the lamp panel when the lamp frame is in use, while "outer side" is the opposite.

[0033] 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 the present invention. 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.

[0034] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0035] like Figure 1-5 As shown, a lamp frame has four L-shaped profiles 1 connected end-to-end, formed by bending sheet metal. The inner side of the lower half of the profile 1 is bent to form a protrusion 51, which supports the edge of a diffuser plate a. This allows the reflector b to press against the diffuser plate a, causing the middle of the diffuser plate a to bulge downwards and extend beyond the inner wall of the lower half of the profile 1. Compared to a design where the diffuser plate a is laid flat on the inner wall of the lower half of the groove, this invention uses the protrusion 51 to support the diffuser plate a, allowing the open end of the reflector b to press downwards against the periphery of the diffuser plate a, causing the middle of the diffuser plate a to bulge downwards and extend beyond the inner wall of the lower half of the profile 1. By extending beyond the lower inner wall of profile 1 and even beyond the lower half of profile 1, while maintaining a fixed light emission distance between the lamp panel and diffuser plate a, the two are lowered as a whole. This utilizes the space at the lower opening of the lamp frame (equivalent to the thickness of the lower half of profile 1), thereby reducing the space occupied by the thickness of diffuser plate a in the height of the lamp frame. This allows for a smaller profile 1 or lamp frame height, achieving a thinner and lighter lamp design, improving the lamp's adaptability in low installation height or recessed applications, reducing material usage and weight, and lowering manufacturing costs.

[0036] Specifically, the ends of two adjacent profiles 1 are connected by corner brackets c, which is existing technology and will not be described in this embodiment.

[0037] Example 1:

[0038] like Figure 6-9 As shown, the sheet material further includes an L-shaped first sheet 2 made of a surface-treatment-free material. One side of the first sheet 2 is bent inward to form a edging 52. The other side of the first sheet 2 is stacked and inserted into the inside of the edging 52. The design of the edging 52 can prevent the two sides of the first sheet 2 from being directly exposed, and prevent the burrs on the sides from scratching people or objects. At the same time, the stacked design can also enhance the structural strength and load-bearing capacity of this part. The part of the first sheet 2 located in the middle of the profile 1 is bent to form a 7-shaped support plate 53. The two sides of the support plate 53 are respectively connected to the upper half and the lower half of the profile 1, which can enhance the torsional resistance of the profile 1 and improve the structural stability of the profile 1. The part of the first sheet 2 located in the lower half of the profile 1 is bent to form a protrusion 51.

[0039] Furthermore, the edging 52 is located at the upper or lower end of the profile 1.

[0040] Furthermore, the portion of the first plate 2 located on the outer side of the lower half of the profile 1 is bent to form a stepped structure 54. The stepped structure 54 can enhance the torsional and bending resistance of the lower half of the profile 1 and improve the structural strength of this part.

[0041] Furthermore, the portion of the first plate 2 located on the inner side of the upper half or the inner side of the lower half of the profile 1 is bent to form a corrugated plate 55. The corrugated structure can enhance the torsional and bending resistance of the upper or lower half of the profile 1 and improve the structural strength of this part.

[0042] Example 2:

[0043] like Figure 10-12 As shown, the sheet material further includes an L-shaped second sheet 3 and an L-shaped third sheet 4 made of a surface-treatment-free material. The third sheet 4 is placed inside the second sheet 3. Both sides of the second sheet 3 are bent inward to form edging 52. The two sides of the third sheet 4 are respectively stacked and inserted into the inner side of the adjacent edging 52. The design of the edging 52 can prevent the two sides of the second sheet 3 and the third sheet 4 from being directly exposed, and prevent the burrs on the sides from scratching people or objects. At the same time, the stacked design can also enhance the structural strength and load-bearing capacity of this area. The middle part of the third sheet 4 is bent to form a 7-shaped support plate 53. The support plate 53 will increase the connection points between the third sheet 4 and the second sheet 3, and improve the torsional and bending resistance of the profile 1. The lower half of the third sheet 4 is bent to form a protrusion 51. Through the stacking of the second sheet 3 and the third sheet 4, the local thickness of the profile 1 can be increased, and its structural stability can be improved.

[0044] Furthermore, the lower half of the second plate 3 near the middle is bent to form a stepped structure 54. The stepped structure 54 can enhance the torsional and bending resistance of the lower half of the profile 1 and improve the structural strength of this part.

[0045] Furthermore, the upper part of the second plate 3 is bent to form a corrugated plate 55.

[0046] Furthermore, the upper part of the third plate 4 is bent to form a wave plate 55.

[0047] In this embodiment, the wave structure can enhance the torsional and bending resistance of the upper half of the profile 1, improve the mechanical properties of this part, and thus improve the overall structural stability of the lamp frame.

[0048] Furthermore, the sheet material is a surface-treatment-free material, such as stainless steel, pre-oxidized alumina, weathering steel, or engineering plastic. When the first sheet 2, the second sheet 3, and the third sheet 4 are made of metal, the corresponding sheets are all bent into shape by bending equipment. The heat-free bending process not only maintains the integrity and aesthetics of the profile 1 surface, but also saves mold opening costs and improves the production efficiency of the profile 1.

[0049] Obviously, the embodiments described above are only some embodiments of this utility model, not all embodiments. The accompanying drawings show preferred embodiments of this utility model, but do not limit the patent scope of this utility model. This utility model can be implemented in many different forms; rather, the purpose of providing these embodiments is to provide a more thorough and comprehensive understanding of the disclosure of this utility model. Although this utility model 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 specific embodiments, or make equivalent substitutions for some of the technical features. Any equivalent structures made using the content of this utility model specification and drawings, directly or indirectly applied to other related technical fields, are similarly within the patent protection scope of this utility model.
