The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0038] Example 1

[0039] refer to Figures 1 to 4This embodiment provides a light source module fixing structure, including a light source module 1, an elastic connecting plate 2 and a lamp body 3. The light source module 1 includes a substrate 11 and a light-emitting unit 12 fixed to the substrate 11. The substrate 11 is provided with a first through hole 111, wherein the light-emitting unit 12 is a plurality of LED lamp beads. The elastic connecting plate 2 includes a bottom wall 21, a side wall 22 and a fixing column 23. The bottom wall 21 and the side wall 22 surround and form a receiving cavity 24. The fixing column 23 protrudes from the bottom wall 21 toward the receiving cavity 24, and the interior of the fixing column 23 is a hollow structure. The lamp body 3 includes a shell 31 and a fastener 32. The bottom of the shell 31 is provided with a second through hole 311. The fixing column 23 is embedded in the first through hole 111, the light source module 1 is installed in the accommodating cavity 24, the elastic connecting plate 2 is installed in the shell 31, the fastener 32 passes through the second through hole 311 and is fixedly connected to the inside of the fixing column 23, and the fixing column 23 and the first through hole 111 are interference fit connected.

[0040] There can be multiple first through holes 111, fixing columns 23 and second through holes 311, and the numbers of the three correspond to each other. In this embodiment, the fastener 32 is a fixing screw.

[0041] During installation, the first through hole 111 is first nested in the fixing post 23. Since the fixing post 23 has a certain degree of elasticity, the first through hole 111 can be interference-fitted with the fixing post 23, thereby achieving the fixation and connection between the light source module 1 and the elastic connecting plate 2. Then, the elastic connecting plate 2 connected to the light source module 1 is placed on the inner bottom of the housing 31, so that the fixing post 23 is aligned with the position of the second through hole 311, and the fastener 32 is screwed into the fixing post 23 through the second through hole 311. When the fastener 32 is screwed into place, the fixing post 23 undergoes lateral expansion deformation due to the squeezing force of the fastener 32. At this time, the fixing post 23 also applies a corresponding squeezing force to the first through hole 111, so that the fixing post 23 and the first through hole 111 are tightly connected and interference-fitted, achieving a stable connection between the light source module 1, the elastic connecting plate 2 and the lamp body 3, and high safety. The light source module 1 is fixed to the lamp body 3 via the elastic connecting plate 2, and the fixing structure is simple, and the installation process is convenient and efficient.

[0042] It should be noted that the dimensions of the light source module 1 and the elastic connection plate 2 match, and the dimensions of the elastic connection plate 2 match those of the lamp body 3. The bottom surface of the base plate 11 is attached to the bottom wall 21, the edge of the base plate 11 abuts against the inner side of the side wall 22, and the outer side of the side wall 22 abuts against the inner side wall of the housing 31. The fastener 32 is connected to the fixing post 23 by an interference fit. By setting the dimensions of the light source module 1, the elastic connection plate 2, and the lamp body 3 to match and fit together, there is no space for offset or looseness between the three, making the connection between the three tighter and more stable, which helps to further improve the stability and reliability of the light source module fixing structure.

[0043] The fixing post 23 includes an end face 231 at the top, a peripheral surface 232 connected to the outer periphery of the end face 231, and a through-slot 233. The through-slot 233 extends to both the end face 231 and the peripheral surface 232. Providing the through-slot 233 on the fixing post 23 provides more room for expansion, making the interference fit between the fastener 32, the fixing post 23, and the first through-hole 111 tighter and more secure, thereby improving the stability and reliability of the light source module fixing structure.

[0044] The through-slot 233 is L-shaped, extending radially from the end surface 231 and axially from the peripheral surface 232. It is understood that one end of the through-slot 233 is located radially from the end surface 231 but does not penetrate the end surface, while the other end is located axially from the peripheral surface 232 but does not penetrate the peripheral surface. This provides ample lateral expansion space for the fixing post 23, allowing the fixing post 23 to exert greater extrusion force on the first through-hole 111, thereby improving the stability of the light source module fixing structure.

[0045] In this embodiment, the width of the through-slot 233 is d1, and the diameter of the end surface 231 is d2, where 1 / 6 d2 ≤ d1 ≤ 1 / 5 d2. Preferably, d1 = 1 / 5 d2. This ensures sufficient expansion space for the fixing post 23 while also ensuring sufficient retention between the fastener 32 and the fixing post 23, thereby enhancing the connection stability between the first through-hole 111, the fixing post 23, and the fastener 32.

[0046] The first through hole 111 is provided at the edge of the substrate 11. An opening 112 is provided at the edge of the substrate 11 corresponding to the first through hole 111. The opening 112 is connected to the first through hole 111. The opening 112 can provide a certain amount of tension for the first through hole 111, making it easier for the first through hole 111 to be nested in the fixing column 23, thereby reducing the difficulty of installing the light source module fixing structure and improving the convenience of installing the light source module fixing structure.

[0047] In this embodiment, the diameter of the end surface 231 is d2, and the diameter of the first through hole 111 is d3, where d2 ≥ d3. This ensures a sufficient interference fit between the fixing post 23 and the first through hole 111, preventing the first through hole 111 from slipping out of the fixing post 23. This prevents the light source module 1 from shifting or becoming loose, and ensures a stable connection between the light source module 1 and the elastic connection plate 2.

[0048] The light source module fixing structure of this embodiment realizes the fixation between the light source module and the lamp body by setting an elastic connecting plate. The fixing structure is simple, and the installation is convenient and efficient. The connection relationship between the light source module, the elastic connecting plate and the lamp body is stable, and the light source module is not easy to loosen, which improves the safety of the lamp. By setting a through groove, sufficient expansion space is provided for the fixing column, which is beneficial to improving the stability and reliability of the light source module fixing structure. By setting an opening, tension is provided for the first through hole, so that the first through hole is easier to nest into the fixing column, which is beneficial to improving the installation convenience of the light source module fixing structure.

[0049] Example 2

[0050] As a further optimization of Example 1, Figures 1-4 Based on the reference Figure 5 The elastic connection plate 2 is provided with a latch 25, which extends from the side wall 22 toward the accommodating cavity 24. The lower end of the latch 25 abuts against the upper surface of the substrate 11. In this embodiment, the latch 25 is an inverted latch type, with a narrow upper end and a wide lower end. There is an inclined surface between the upper and lower ends, which further facilitates the insertion of the substrate 11.

[0051] Because the buckle 25 is elastic, when the substrate 11 is installed into the elastic connecting disk 2 in the vertical direction, the substrate 11 moves downward along the inclined surface on the buckle 25, and the buckle 25 bounces outward due to the squeezing force of the substrate 11. When the substrate 11 reaches below the buckle 25, the buckle 25 bounces back because it is no longer subjected to the squeezing force. At this time, the lower end of the buckle 25 abuts against the upper surface of the substrate 11, thereby limiting the movement of the substrate 11 in the vertical direction, further consolidating the connection relationship between the light source module 1 and the elastic connecting disk 2, having strong reliability, and the installation method is simple, convenient, easy to operate, and has high installation efficiency.

[0052] Preferably, there are two clips 25, and the two clips 25 are positioned opposite each other. The two clips 25 are located on opposite sides of the side wall 22, which can make the clips 25 more balanced and stable in limiting and fixing the substrate 11, ensuring that the light source module 1 is stably and firmly fixed to the elastic connecting plate 2, further improving the reliability of the light source module fixing structure.

[0053] The elastic connecting plate 2 is provided with a wire groove 26, which is formed in the side wall 22. There are multiple fixing posts 23, and the wire groove 26 is located between two adjacent fixing posts 23. The light source module 1 also includes an electrical connection line for electrically connecting the light-emitting unit 12 to an external power source. The electrical connection line can pass through the wire groove 26 and pass out to the outside of the light source module fixing structure to be electrically connected to the external power source. The placement of the wire groove 26 between two adjacent fixing posts 23 prevents interference between the electrical connection line and the fixing posts 23, which helps ensure smooth installation and normal use of the lamp.

[0054] Preferably, there are three fixing posts 23 , and the three fixing posts 23 are distributed in a triangular pattern on the elastic connection plate 2 , which helps to further improve the stability of the connection between the light source module 1 and the elastic connection plate 2 , thereby improving the stability and reliability of the light source module fixing structure.

[0055] The light source module fixing structure of this embodiment can further limit and fix the light source module by setting a snap buckle, further consolidate the connection relationship between the light source module and the elastic connecting plate, have strong stability, simple installation method, and convenient operation; by setting a wire groove and setting it between two adjacent fixed columns, it can avoid mutual interference between the electrical connection wire and the fixed column, ensuring the normal installation and use of the lamp; by setting the number of fixed columns to three and distributing them in a triangular pattern, it is beneficial to further improve the stability and reliability of the light source module fixing structure.

The lampshade 100 is disposed at the light-emitting end of the housing 31. Light emitted by the light source module 1 is emitted to the outside through the lampshade 100. In some embodiments, the lampshade 100 can be connected to the housing 31 by screwing or snapping.

[0058] A wire outlet hole is provided on one side of the housing 31 , and the electrical connection wires on the light source module 1 pass through the wire groove 26 and the wire outlet hole to the outside of the lamp body 3 to be electrically connected to an external power supply component.
