Description

Technical Field

[0001] This utility model belongs to the field of light source board assembly technology. Specifically, this utility model relates to a structure that optimizes the assembly strength of a light source board. Background Technology

[0002] When designing luminaire assemblies, it is generally desirable for the luminaire to have strong installation strength after the internal parts are assembled to ensure that the luminaire meets vibration test requirements. This often leads to the use of more complex installation methods when designing the assembly of wide light source panels inside the luminaire, in order to ensure installation strength. See the attached diagram in the instruction manual. Figure 4 As shown, to solve the problem of installing wide light source boards, lighting manufacturers typically use light source board fasteners and screws to secure the light source board, ensuring installation strength. Using light source board fasteners and screws increases the number of parts used, raising costs; furthermore, securing the light source board with fasteners and then tightening with screws increases assembly complexity and time; and because screws are used, screw posts are required on the reflector, which can easily cause shrinkage marks on the reflector, resulting in poor appearance and scrapped parts, further increasing costs.

[0003] Chinese patent (publication number: 209782438U) discloses a battery-operated lamp. The lamp cover has a sealing groove, within which a first sealing ring is installed. The battery is installed inside the lamp body, and a light source plate mounting block is positioned inside the lamp body. The light source plate is bolted to the mounting block. The lamp cover and lamp body are bolted together. Several flanged pressure plates are provided on the upper part of the lamp body. After the lamp cover and lamp body are closed, the flanged pressure plates press tightly against the lower end of the reflector bowl, causing the reflector bowl, the light-transmitting glass plate, and the second sealing ring to be sequentially stacked and tightly installed inside the lamp cover. A locking device is installed at the joint between the lamp cover and the lamp body. The bottom of the lamp body also has a USB interface and a switch button, and a handle is installed on the side of the lamp body. However, the use of bolts requires bolt posts on the reflector bowl, which can easily cause shrinkage marks, resulting in poor appearance and scrapped parts, further increasing costs.

[0004] This utility model is designed to solve the above-mentioned problems and aims to provide a structure that optimizes the assembly strength of the light source board, eliminating the need for screw post structures to fix the light source board. To achieve the above objective, the technical solution adopted by this utility model is as follows: a structure that optimizes the assembly strength of the light source board, comprising a reflector bowl, a light source board, and a lamp body, wherein the reflector bowl and the lamp body are provided with an optimization structure.

[0005] The optimized structure includes a limiting and fixing rib and a snap-fit ​​assembly.

[0006] The buckle assembly includes a first connecting plate, which is connected to the reflector bowl. A limiting groove is formed between the first connecting plate and the reflector bowl, and the light source plate is snapped into the limiting groove.

[0007] The first connecting plate has a U-shaped cross-section.

[0008] The limiting and fixing rib is integrally formed with the lamp body.

[0009] One end of the limiting and fixing rib has a guide plane, and the guide plane and the limiting and fixing rib are at a 45-degree angle.

Compared with traditional bolt fixing, the snap-fit ​​assembly is easier to assemble, saves time, and reduces costs; this structure eliminates the screw post of the reflector bowl, eliminates shrinkage marks, improves the yield rate, and reduces the overall cost of the lamp.

[0013] A limiting groove is formed between the first connecting plate and the reflector bowl, fixing one end of the light source board within the limiting groove and restricting the movement of the light source board 2 in space. At the same time, the elastic deformation of the first connecting plate enables the light source board to be disassembled and assembled without damage.

[0021] The specific embodiments of the present invention will be further described in detail below with reference to the accompanying drawings, in order to help those skilled in the art to have a more complete, accurate and in-depth understanding of the inventive concept and technical solution of the present invention, and to facilitate its implementation.

[0022] like Figures 1 to 3 As shown, a structure for optimizing the assembly strength of a light source board includes a reflector bowl 1, a light source board 2, and a lamp body 3. An optimization structure 4 is provided on the reflector bowl 1 and the lamp body 3. The reflector bowl 1, as the core optical reflection component, is responsible for directional reflection of the light emitted from the light source board 2, and also serves as the mounting base for the snap-fit ​​assembly 41. The light source board 2, as the carrier of the LED light source, achieves precise positioning through the coordinated fixing of the snap-fit ​​assembly 41 and the limiting fixing rib 401. The lamp body 3 is the main structural support. The optimization structure 4 fixes the light source board 2.

[0023] The optimized structure 4 includes a limiting and fixing rib 401 and a snap-fit ​​assembly 41. The limiting and fixing rib 401 is provided on the lamp body 3, and the snap-fit ​​assembly 41 is connected to the reflector bowl 1. One end of the light source plate 2 is located between the lamp body 3 and the limiting and fixing rib 401, and the other end of the light source plate 2 is connected to the snap-fit ​​assembly 41. The limiting and fixing rib 401 is in close contact with the light source plate 2, restricting the movement of the light source plate 2 in space. Compared with traditional bolt fixing, the snap-fit ​​assembly 41 is easier to assemble, saves labor time, and reduces costs. This structure eliminates the screw post of the reflector bowl 1, eliminates shrinkage marks, improves the yield rate, and reduces the overall lamp cost.

[0024] The snap-fit ​​assembly 41 includes a first connecting plate 411, which is connected to the reflector bowl 1. A limiting groove 412 is formed between the first connecting plate 411 and the reflector bowl 1, and the light source plate 2 snaps into the limiting groove 412. The limiting groove 412 formed between the first connecting plate 411 and the reflector bowl 1 fixes one end of the light source plate 2 in the limiting groove 412, restricting the movement of the light source plate 2 in space. At the same time, the elastic deformation of the first connecting plate 411 allows for the non-destructive assembly and disassembly of the light source plate 2.

[0025] The cross-section of the first connecting plate 411 is U-shaped. A limiting groove 412 is formed between one side of the U-shaped first connecting plate 411 and the reflector bowl 1. When the light source plate 2 shakes slightly...

[0026] The other side of the first connecting plate 411 of the U-shaped structure abuts against the reflector bowl 1, limiting the shaking of the light source plate 2, and also playing a role in buffering and shock absorption.

[0027] The limiting and fixing rib 401 is integrally formed with the lamp body 3. The connection structure between the limiting and fixing rib 401 and the lamp body 3 is stronger and the connection is more stable.

[0028] One end of the limiting and fixing rib 401 has a guide plane 5, and the guide plane 5 and the limiting and fixing rib 401 form a 45-degree angle. The 45-degree inclined plane forms a sliding contact with the edge of the light source plate 2, and the deviation is automatically corrected during the initial assembly.

[0029] The first connecting plate 411 is a one-piece molded polyoxymethylene structure. The first connecting plate 411 is allowed to have a certain degree of elasticity, while also having high strength and fatigue resistance.

[0030] A reinforcing plate 6 is provided on the first connecting plate 411. The reinforcing plate 6 can enhance the connection strength of the first connecting plate 411 and prevent the first connecting plate 411 from breaking after repeated pressing.

[0031] The role and effect of the embodiments

[0032] One end of the light source plate 2 is located between the lamp body 3 and the limiting and fixing rib 401, and the other end of the light source plate 2 is connected to the snap-fit ​​assembly 41. The limiting and fixing rib 401 is in close contact with the light source plate 2, restricting the movement of the light source plate 2 in space. Compared with the traditional bolt fixing, the snap-fit ​​assembly 41 is easier to assemble, saves time, and reduces costs; this structure eliminates the screw post of the reflector bowl 1, eliminates shrinkage marks, improves the yield rate, and reduces the overall cost of the lamp.

[0033] A limiting groove 412 is formed between the first connecting plate 411 and the reflector bowl 1, fixing one end of the light source plate 2 in the limiting groove 412 and restricting the movement of the light source plate 2 in space. At the same time, the elastic deformation of the first connecting plate 411 enables the light source plate 2 to be disassembled and assembled without damage.

[0034] The reinforcement plate 6 can strengthen the connection strength of the first connecting plate 411 and prevent the first connecting plate 411 from breaking after being pressed repeatedly.

[0035] The present invention has been described above by way of example with reference to the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvements made using the inventive concept and technical solution of the present invention; or the direct application of the inventive concept and technical solution to other situations without modification, are all within the protection scope of the present invention.
