Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of lighting equipment, specifically relating to a lamp body structure and a panel lamp. Background Technology
[0002] Panel lights are lighting devices installed in suspended ceilings or ceilings using recessed or surface-mount methods. The light source module of a panel light is located on the side wall or bottom, illuminating the outside through a direct-down light emission method. As panel lights are increasingly used in various lighting environments, the uniformity of light emission from the light-emitting surface has gradually become a key quality point for user experience, thus placing higher demands on the uniformity of light emission in panel lights.
[0003] Existing surface light source fixtures on the market suffer from limitations imposed by their outer frame, causing light around the emitting surface to be absorbed by the side walls, resulting in a noticeable dark band. This is particularly pronounced when panel lights use black frames. When multiple lights are used together, this dark band significantly reduces the immersive lighting experience.
[0004] Existing technology discloses a direct-lit panel light, including a base frame, a PCB board, and a diffuser plate. The base frame includes a base plate and sidewalls, with the sidewalls forming a flared opening around the edge of the base plate. The PCB board is fixedly mounted on the base plate. An LED array can be distributed on the PCB board. The diffuser plate covers the end of the flared opening through a top frame, and the light emitted by the LED array can pass through the diffuser plate and exit the panel light. A reflective film is disposed on the surface of the LED array facing away from the diffuser plate. The surfaces of the base plate and sidewalls can be coated with a reflective film layer or sprayed with reflective paint. This direct-lit panel light uses a coated reflective film layer and a stepped structure for light reflection. However, its reflective structure has multiple levels, and light absorption is still unavoidable. Utility Model Content

[0053] Example 1
[0054] refer to Figures 1-5This embodiment provides a lamp body structure 100 for use in a flat panel lamp or panel lamp. The lamp body structure 100 includes a frame 1, a light source assembly 2, and an optical assembly 3. The frame 1 serves as the main body of the lamp frame 100 and is used to mount the light source assembly 2 and the optical assembly 3. The light emitted by the light source assembly 2 is controlled by the optical assembly 3 before being emitted to the outside. In this embodiment, the frame 1 is a rectangular structure, preferably a square structure. In some embodiments, the shape of the frame 1 may also be triangular, circular, elliptical, regular pentagonal, regular hexagonal, or other polygonal structures.
[0055] In some embodiments, the frame 1 is a one-piece molded structure, such as being manufactured by one-piece stamping. In some embodiments, the frame 1 is a split structure, comprising multiple connected frame edges 11. The frame edges 11 are aluminum profile components, characterized by high structural strength and light weight. The frame edges 11 may have multiple grooves provided according to the requirements of component installation and weight reduction.
[0056] In some embodiments, the frame 11 can be fixed together by seamless welding, riveting, screwing, splicing, or bonding. In other embodiments, corner brackets can be used to fix vertical and adjacent frame 11 together at the corners. The frame 1 of this embodiment is composed of four aluminum profile frame 11 seamlessly connected together.
[0057] In some embodiments, the frame 1 includes a frame 11 and a back plate 110, and the frame 1 has a cavity 12 on its inner side. The cavity 12 is formed by a plurality of frames 11 and back plates 110 surrounding it, and the cavity 12 can serve as both a mounting cavity and a light mixing cavity. The light source assembly 2 is mounted at the bottom of the cavity 12 and emits light during operation. Part of the light is reflected and mixed with the unreflected light in the cavity 12, and then irradiated to the outside from the opening of the cavity 12, which is the light-emitting end of the frame 1.
[0058] The frame 11 includes a first mounting part 111, a second mounting part 112, a side plate 113, and a base 114. The side plate 113 is located on the periphery of the lamp body structure 100. The base 114 and the first mounting part 111 extend from the side plate 113 toward the cavity 12. The second mounting part 112 is located between the base 114 and the first mounting part 111.
[0059] refer to Figure 3The side plate 113 has a first end 1131 and a second end 1132, which are respectively located at the lower and upper ends of the side plate 113. A base 114 extends from the first end 1131 of the side plate 113 toward the cavity 12, for mounting the light source assembly 2; a first mounting portion 111 extends from the second end 1132 of the side plate 113 toward the cavity 12. Thus, the first end 1131 is the light-emitting end of the lamp body structure 100, and the second end 1132 is the light-exiting end of the lamp body structure 100.
[0060] In this embodiment, the length of the base 114 extending from the first end 1131 is greater than the length of the first mounting portion 111 extending from the second end 1132.
[0061] The optical component 3 includes a reflector 31 and a light emitter 32. The light emitter 32 is mounted on the first mounting portion 111, and the reflector 31 is mounted in the second mounting portion 112. The reflector 31 is elastically deformable reflective paper or reflective film. After elastic deformation, the reflector 31 has an arc-shaped structure. That is, after the reflector 31 is mounted to the second mounting portion 112, it arcs outward toward the cavity 12, thereby performing (secondary) reflection processing on the light emitted by the light source component 2.
[0062] The light source assembly 2 is fixedly mounted on the base 114. After power is applied, part of the light emitted by the light source assembly 2 is directly emitted to the outside through the light emitting element 32, and the other part is reflected by the reflector 31 before being emitted to the outside through the light emitting element 32. The light reflected by the reflector 31 and the light that has undergone reflection treatment are mixed in the chamber 12 to make the emitted light uniform and soft.
[0063] Furthermore, the backplate 110 is disposed at the bottom of the frame 1 and is fixedly connected to the frame 11, for example, by inserting it into the backplate mounting slot of the base.
[0064] The first mounting part 111 includes a first base plate 1111 and a first limiting plate 1112. The first base plate 1111 is disposed between the side plate 113 and the first limiting plate 1112, that is, the first limiting plate 1112 is located inside the side plate 113. The first base plate 1111 is connected to both the side plate 113 and the first limiting plate 1112. In this way, the side plate 113, the first base plate 1111, and the first limiting plate 1112 together form a first groove 1113. The first groove 1113 is generally U-shaped.
[0065] The light-emitting element 32 is a diffuser plate, and its material can be PC (Polycarbonate), PMMA (polymethyl methacrylate), or PS (polystyrene), etc. The light-emitting element 32 includes a light-emitting body 321 and a first edge 322, which is disposed on the outer periphery of the light-emitting body 321.
[0066] The light-emitting body 321 can have a frosted structure or a tapered or prismatic microstructure on its surface to adjust the uniformity of light emission and to prevent glare. In this embodiment, the light-emitting body 321 is a flexible diffuser plate structure for preventing glare. In some embodiments, the light-emitting element 32 is a PVC diffuser film, which has sound absorption properties. While achieving an anti-glare light emission effect, it can also absorb ambient noise to achieve a noise reduction effect.
[0067] The first edge 322 may be made of the same or different material as the light-emitting body 321, and the first edge 322 is connected to the first groove 1113.
[0068] The second mounting portion 112 includes a second groove 1121 and a limiting groove 1122. The second groove 1121 is located above the base 114, and the limiting groove is located inside the first limiting plate 1112. Figure 3 and Figure 4 The limiting groove 1122 and the second recess 1121 are located on the upper and lower mounting portions of the second mounting portion 112, respectively. One end of the reflector 31 is inserted into the second recess 1121, and the other end is inserted into the limiting groove 1122.
[0069] Furthermore, the second mounting portion 112 also includes a second limiting plate 1123 and a bending member 1124. The second limiting plate 1123 is formed by the first limiting plate 1112 extending downward toward the base 114 at its junction with the first base plate 1111, and is parallel to the side plate 13. The bending member 1124 is formed by the first limiting plate 1112 first protruding toward the cavity 12 on its inner side, and then extending obliquely downward toward the base 114. The bending member 1124 has an arc-shaped bending structure, and a limiting groove 1122 is formed by the bending member 1124 and the second limiting plate 1123 surrounding each other. In some embodiments, the bending member 1124, the second limiting plate 1123, and a portion of the first limiting plate 1112 surround each other to form the limiting groove 1122. The groove size of the limiting groove 1122 is smaller than the groove size of the second groove 1121. When installing the reflector 31 onto the second mounting part 112 of the frame 11, the lower end of the reflector 31 is first inserted into the second groove 11221, and then the reflector 31 is bent in an arc shape and the upper end is inserted into the limiting groove 1122.
[0070] Further reference Figure 3 The light source assembly 2 includes a substrate 21 and LED beads 22, with the LED beads 22 bonded and fixed to the substrate 21. In this embodiment, the LED beads 22 are soldered and fixed to the substrate 21 using an SMD surface mount method, and the LED beads 22 are evenly distributed on the substrate 21 to ensure uniform light emission. The substrate 21 is fixedly mounted on the base 114; furthermore, the substrate 21 is fixedly connected to the back plate 110, specifically by fasteners 5, such as screws, to lock the substrate 21 and the back plate 110 together. In some embodiments, a buffer pad 115 is also provided between the substrate 21 and the back plate 110. In other embodiments, the light source assembly 2 is directly fixedly mounted on the base 11, and the substrate 21 is supported on the back plate 110.
[0071] It should be noted that the multiple LED beads 22 that are evenly distributed together emit light to form a light-emitting surface 23. This light-emitting surface 23 is a plane located below the second groove 1121 and has a normal M.
[0072] Reference Figures 2-5 Let L1 be the direction parallel to the normal M. Along the first direction L1, the height of the reflector 31 before being inserted into the second mounting portion 112 is H, i.e., the original height of the reflector 31 is H. The distance between the bottom end of the second groove 1121 and the top end of the limiting groove 1122 is D1. The original height of the reflector 31, H, has a relationship with the distance D1: H > D1. It can be understood that the original height of the reflector 31 before being inserted into the second mounting portion 112 is H; after being inserted into the second groove 1121 and the limiting groove 1122 of the second mounting portion 112, the reflector 31 is curved and protrudes into the cavity 12. At this time, the arc length of the arc containing the reflector 31 is H, and the radius R is greater than 125mm. After the curved bending, the height of the reflector 31 is equal to the distance D1.
[0073] The reflector 31 can be a reflective film or reflective paper structure with a reflectivity of over 97%. Combined with the arc-shaped convex design of the reflector 31 towards the cavity 12, light can undergo primary and secondary reflection. During the secondary reflection, the reflector 31 located on the opposite side refracts the light back for reflection, allowing the light-emitting element (flexible light-emitting film) near the side plate to obtain sufficient brightness.
[0074] Along the first direction L1, the distance between the light-emitting surface 32 and the second end 1132 (light-emitting end) of the side plate 113 is D2, where D2 is the height of the cavity 12, i.e. the light mixing cavity. The value of D2 is in the range of 70-75mm, preferably 73mm.
[0075] The second direction L2 is perpendicular to the normal M and also perpendicular to the first direction L1. Along the second direction L2, the distance between the outer wall of the side plate 113 and the adjacent LED bead 22 is D3, where D ranges from 23 to 25 mm, preferably 24 mm. The LED beads 22 are arranged in a 30*50 rectangular array for light source layout. Combined with the light control of the reflector and the light-emitting element (flexible light-emitting film), the lamp body structure achieves a light emission uniformity of over 92%.
[0076] Furthermore, along the second direction L2, the distance between the outer side wall of the side plate 113 and the inner side wall of the first limiting plate 1112 is D4. It can be understood that D4 is the width of the second end 1132 (light-emitting end), ranging from 5.5-6.5 mm, preferably 6 mm. That is, the frame thickness can be 6 mm, achieving a truly narrow frame. This 6 mm thick frame retains only the first groove structure of the light-emitting element (light-emitting soft film) at the light-emitting end, enabling the light-emitting surface to achieve a rendering rate of 97.02%.
[0077] The second groove 1121 is formed by the third limiting plate 1125 and the fourth limiting plate 1126 on opposite sides and the second bottom plate 1127 at the bottom. The third limiting plate 1125 is located inside the fourth limiting plate 1126, and the height of the third limiting plate 1125 is less than the height of the fourth limiting plate 1126.
[0078] Along the second direction L2, the distance between the outer side wall of the side plate 113 and the inner side wall of the third limiting plate 1125 is D5, where D5 is 11mm wide. By setting this size, the proportion of the cavity 12 (mixing cavity) reaches 94.57%, so that the light can be fully mixed in the cavity 12, avoiding the side plate of the frame from casting a projection on the light-emitting element.
[0079] The lamp body structure provided in this embodiment has a reflector located in the second mounting part of the side plate, and the arc-shaped convex cavity for light mixing reduces light absorption by the side plate while cooperating with the light emitting component to control the light emitted by the light source assembly, making the light output uniform. Moreover, the frame of the lamp body structure adopts a narrow frame, and both the light mixing cavity and the light emitting component have large dimensions, avoiding the situation that the side of the frame is too dark, and the optical uniformity reaches more than 92%.
[0080] Example 2
[0081] exist Figures 1-5 Based on reference Figure 6 In the lamp body structure 100 of this embodiment, the optical component 3 also includes a light mixing element 33, which is a transparent element that can divide the cavity 12 into a first light mixing cavity 121 and a second light mixing cavity 122 that are not interconnected.
[0082] The light emitted by the light source assembly 2 passes through the first mixing cavity 121 and the second mixing cavity 122 and is then emitted to the outside from the light emitting element 32. At this time, the reflector 31 only reflects the light from the second mixing cavity 122.
[0083] Since the light mixing component 33 separates the first light mixing cavity 121 and the second light mixing cavity 122, any foreign objects such as dust or insects that enter the first light mixing cavity 121 from the substrate 21 will be blocked outside the second light mixing cavity 122, thus avoiding affecting the light mixing effect of the second light mixing cavity 122.
[0084] Dust, insects, and other foreign objects are blocked outside the second mixing cavity 122, which also prevents shadows from appearing on the light-emitting surface of the lamp body mechanism 100 due to the presence of foreign objects, further ensuring the uniformity of light output.
[0085] The light mixing element 33 includes a light mixing body 331 and a second edge 332, which is disposed on the outer periphery of the light mixing body 331. The second edge 332 is connected to the second groove 1121 and to the lower end of the reflector 31, clamping the reflector 31 in the second groove 1121.
[0086] The double-layer structure formed by the light mixing element 33 and the light emitting element 32 can achieve a double absorption effect on the sound around the lamp body mechanism 100, thereby achieving the effect of noise reduction and reducing echo.
[0087] Example 3
[0088] exist Figures 1-6 Based on, refer to Figure 7 This embodiment provides a panel light 300, including a sealing member 200 and a lamp body structure 100 of embodiment 1 or embodiment 2.
[0089] In the panel light 300, multiple frames 11 are fixedly connected together by seamless splicing or welding to form a frame 1. A back plate 110 is set at the bottom of the frame 1, and the light source assembly 2 is fixed on the back plate 110.
[0090] On the first mounting portion 111 of the frame 11, a serrated structure 1114 is provided on the side wall of the first groove 1113. The sealing member 200 is a silicone pad or a rubber pad, and a toothed structure is provided corresponding to the serrated structure 1114. In some embodiments, the sealing member 200 can be integrated with the light-emitting member 32, that is, the sealing member 200 and the first edge 322 are integrally formed. Since the light-emitting body 321 is a flexible soft film structure, the sealing member 200 at the first edge 322 can be well installed into the first groove 113. The sealing member 200 is embedded and connected to the first groove 1113, realizing the sealing and waterproof function of the panel light on the face.
[0091] The panel light provided in this embodiment uses a lamp body structure that prevents uneven brightness between the side panel near the frame and the light-emitting surface, making the light-emitting surface more uniform and soft. When multiple panel lights are spliced together to form a lighting system, the lines and contours will not have any breaks in the light-emitting surface, ensuring the quality of light output.
[0092] The above description is merely an example and illustration of the structure of this utility model, and while the description is quite specific and detailed, it should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these obvious substitutions all fall within the protection scope of this utility model.
