[Specific implementation method]

[0025] The following examples are used to illustrate the present invention but are not intended to limit the scope of the present invention.

[0026] A preferred embodiment of the present invention, please refer to Figure 1 As shown, the present invention discloses a quick-install light source module, comprising: an optical component 100, a light source board 200 and a circuit board 300. The circuit board 300 is provided with electrical components 3001 such as circuits, light source drivers and connection terminals. The edge of the optical component 100 is provided with at least two first snap-fit ​​elements 101 arranged along the circumference of the optical component 100 and protruding toward the light incident surface 1001. The first snap-fit ​​elements 101 are arranged at an angle to the light incident surface 1001 of the optical component 100. Figure 1 As shown, in this embodiment, the first snap element 101 is provided at the edge of the optical component 100 and forms a 90° angle with the light incident surface 1001 of the optical component 100. There are two first snap elements 101, and the two first snap elements 101 are arranged at 180° in the circumferential direction of the optical component 100. In other embodiments, the first snap element 101 is provided to protrude from the light incident surface 1001 of the optical component 100 toward the light incident surface 1001, and is particularly preferably provided to protrude from the edge of the light incident surface 1001 of the optical component 100 toward the light incident surface 1001. The side portion of the first snap element 101 is recessed inward from its outer surface to form a circuit board slot 1011. The circuit board slot 1011 is used to engage with the circuit board 300 to clamp the circuit board 300 within the circuit board slot 1011. The circuit board 300 is provided with a first snap hole 301a, which is used for the first snap element 101 to pass through and to snap the circuit board 300 into the circuit board slot 1011 of the first snap element 101. Figure 1As shown, the circuit board 300, the light source board 200 and the optical component 100 are arranged in sequence, the first snap element 101 is inserted into the first snap hole 301a and the circuit board 300 is snapped into the circuit board slot 1011, the light source board 200 is arranged between the light incident surface 1001 of the optical component 100 and the circuit board 300, and the light source board 200 is provided with a light source 201 on the side facing the light incident surface 1001 of the optical component 100, and the light source 201 is preferably an LED light source. Figure 1 As shown, in this embodiment, the light source board 200 is preferably made of ceramic, and the light source 201 is arranged in the middle of the light source board 200. Figure 1 As shown, the circuit board 300, the light source board 200 and the optical component 100 are arranged in sequence from bottom to top, the light source 201 of the light source board 200 is facing upward, the first snap element 101 of the optical component 100 is inserted into the first snap hole 301a, the circuit board slot 1011 is snapped with the circuit board 300, that is, the first snap element 101 forms a snap connection with the edge of the first snap hole 301a, so that the light source board 200 is clamped between the light incident surface 1001 of the optical component 100 and the circuit board 300, the circuit board 300, the light source board 200 and the optical component 100 form a light source module of an integrated structure, and then the circuit between the light source 201 and the electrical components of the circuit board 300 is connected through a power line, that is, the light source module is assembled. After the light source module is energized, the light emitted by the light source 201 of the light source board 200 enters from the light incident surface 1001 of the optical component 100, and is emitted from the light emitting surface 1002 of the optical component 100 after being processed by the optical path of the optical component 100. The number of light sources 201 is one or more. When there are multiple light sources 201, the multiple light sources 201 are arranged in an array or in a ring. Figure 2 As shown in FIG. 1 , in this embodiment, a plurality of light sources 201 are arranged in an array. It should be noted that the “direction of the light incident surface” in the present invention refers to the direction outward from the light incident surface, i.e. Figure 1 As shown, the light incident surface is arranged downward, and the direction of the light incident surface is downward.

[0027] When assembling the quick-release light source module of the present invention, the light source board 200 is placed on the circuit board 300, and the first snap element 101 of the optical component 100 is inserted into the first snap hole 301a from top to bottom. When the first snap element 101 is inserted into the first snap hole 301a, it is deformed. When inserted into place, the circuit board 300 and the circuit board slot 1011 form a snap connection structure, so that the light source board 200 is clamped between the light incident surface 1001 of the optical component 100 and the circuit board 300, that is, the circuit board 300, the light source board 200 and the optical component 100 form an integrated light source module. The quick-release light source module of the present invention has the advantages of simple assembly work, fewer processes and short working hours, which can improve the work efficiency of production line workers.

[0028] As a preferred solution, in this embodiment, the circuit board 300 is provided with heat dissipation holes 301b, which correspond to the light source board 200. Generally, the light source 201 is located in the center of the light source board 200, and the heat dissipation holes are arranged corresponding to the position of the light source 201. Heat generated by the light source 201 when emitting light is dissipated through the heat dissipation holes, improving the heat dissipation capacity of the light source module and reducing the risk of damage due to overheating. This is suitable for the production of higher-power light source modules.

[0029] As a preferred solution, Figure 1 As shown, in this embodiment, the light incident surface 1001 of the optical component 100 is further provided with a plurality of second snap-fit ​​elements 102 arranged along the circumference of the optical component 100 and protruding toward the light incident surface 1001. The plurality of second snap-fit ​​elements 102 jointly clamp the light source board 200 to position and clamp the light source board 200. Figure 2 As shown, in the present embodiment, the number of the second snap elements 102 is two, and the two second snap elements 102 are arranged at 180° along the circumferential direction, and the second snap elements 102 extend slightly outward from the light incident surface 1001 of the optical component 100. The connecting line of the two second snap elements 102 is arranged perpendicular to the connecting line of the two first snap elements 101. During the assembly process, the light source board 200 is placed on the circuit board 300, and the optical component 100 is squeezed with force. When the first snap element 101 is inserted into the first snap hole, the light source board 200 overcomes the elastic force of the second snap elements 102 and is embedded in the space enclosed by the second snap elements 102, and is clamped and fixed by the second snap elements 102. Alternatively, during assembly, the light source board 200 is first pressed into the space enclosed by the second snap elements 102, and then the first snap element 101 is inserted into the first snap hole. The second snap-fit ​​element 102 clamps the light source board 200, making the light source board 200 of the light source module structure more stable and reliable, and reducing the risk of damage to the light source 201 of the light source board 200. Furthermore, to better clamp and position the light source board 200, the side of the second snap-fit ​​element 102 is provided with a light source board clamping groove (not shown) that is recessed inward from its outer surface.

[0030] As a preference, the circuit board 300 is provided with an optical component fool-proofing hole 302 for the second snap element 102 to pass through. After assembly, the second snap element 102 is inserted into the optical component fool-proofing hole 302 to position and fool-proof the optical component 100.

[0031] Further, such as Figure 1As shown, an introduction bevel 105 is provided at one end of the first snap element 101 away from the light incident surface 1001 of the optical component 100. The first snap element 101 protrudes outward and extends from the edge of the optical component 100. The end away from the light incident surface 1001 of the optical component is a free end, which is used to be inserted into the first snap hole. The introduction bevel 105 is provided at the free end of the first snap element 101 to facilitate the introduction of the first snap element 101 into the first snap hole during installation.

[0032] Further, such as Figure 1 As shown, a circuit board pressing portion 106 is provided on the outer side of the first snap element 101, and the circuit board pressing portion 106 is provided between the circuit board slot 1011 and the optical component 100. The circuit board pressing portion 106 is provided to realize a limiting function. During the assembly process, the light incident surface 1001 of the optical component 100 is prevented from being squeezed onto the light source 201 of the light source board 200, thereby avoiding damage to the light source and ensuring the yield rate.

[0033] Further, such as Figure 1 As shown, the first snap element 101 is provided with a mounting through hole 104. The mounting through hole 104 is recessed from the light-emitting surface 1002 of the optical component 100 toward the light-incident surface 1001 and passes through the first snap element 101. When the light source module is mounted on the lamp holder of the lamp, screws are used to connect the optical component 100 to the lamp holder through the mounting through hole 104 from the light-emitting surface 1002 to form a stable connection structure.

[0034] Further, such as Figure 1 As shown, the light emitting surface 1002 of the optical component 100 is provided with a boss 103. The boss 103 has the function of focusing and diffusing light, so that the light emitted by the light source is transmitted through the optical component 100 to achieve the effect required by the user.

[0035] Further, such as Figure 1 As shown, a cable groove 303 is provided on the edge of the circuit board 300. The cable groove 303 is a U-shaped groove opened from the edge of the circuit board 300 for receiving a power cord.

[0036] In the above embodiment, there are two first snap elements 101 and two second snap elements 102. It should be noted that three, four, or six first snap elements 101 and second snap elements 102 may also be provided. Generally, the implementation of three first snap elements 101 and second snap elements 102 is the most stable and reliable structure. For light source modules with higher product quality requirements and higher power, three first snap elements 101 and second snap elements 102 may be provided and evenly arranged circumferentially along the light incident surface 1001 of the optical component 100.

[0037] In the above preferred embodiment, the heat dissipation holes and the first snap holes are provided separately, and it is necessary to process multiple holes on the circuit board to serve as the heat dissipation holes and the first snap holes respectively. As another preferred embodiment, this embodiment is basically the same as the above preferred embodiment, except that:

[0038] like Figure 2 As shown, in this embodiment, an integrated hole 301 is provided on the circuit board 300 to serve as both a heat dissipation hole and a first snap hole. It should be noted that, in this embodiment, the integrated hole is roughly circular, and in other embodiments, the integrated hole can also be a polygonal hole or an irregular hole. In this embodiment, the heat dissipation hole and the first snap hole are connected to form an integrated hole 301. The heat dissipation hole and the first snap hole form an integrated hole 301. The area of ​​the integrated hole 301 is large, and most of the area of ​​the light source board 200 is directly in contact with the air, which expands the heat dissipation area and improves the heat dissipation effect. The circuit board slot 1011 is provided on the outside of the first snap element 101, and the first snap element 101 cooperates with the edge of the integrated hole 301 to form a snap connection.

[0039] Furthermore, in this embodiment, if Figure 2 As shown, the second snap element 102 protrudes from the edge of the optical component 100 toward the light incident surface and extends slightly outward, forming a roughly L-shaped shape. A limiting protrusion is also provided on the inner side wall of the second snap element 102. The optical component anti-fool hole 302 is formed by being recessed from the inside to the outside at the edge of the integrated hole 301.

[0040] Furthermore, in this embodiment, the light source board 200 and the integrated hole 301 are both circular, with the diameter of the light source board 200 being larger than that of the integrated hole 301. A post-clearing groove 202 for the first snap element 101 to pass through is recessed inward from the edge of the light source board 200. That is, a U-shaped groove is provided on the edge of the light source board 200 for the first snap element 101 to pass through. During assembly, operators on the production line can quickly find the correct assembly position and complete the assembly quickly.

[0041] In this embodiment, an integrated hole 301 is provided by hollowing out the circuit board 300 between the heat dissipation hole and the first snap hole. This makes machining the circuit board 300 easier, improving production efficiency. A post-relief slot 202 is provided on the light source board 200, which serves both as a safety feature and as a positioning mechanism to prevent the light source board 200 from shifting. The integrated hole arrangement ensures unrestricted rotational freedom between the optical component 100 and the circuit board 300. The optical component safety hole 302 is provided on the circuit board 300, and the second snap element 102 is inserted into the optical component safety hole 302, providing both a safety feature and a positioning mechanism.

[0042] The present invention also discloses a lamp, which includes the quick-install light source module described in the above embodiment. Those skilled in the art will understand that the lamp also needs to include an electrical box, a reflector, a dust cover, etc. In order to clearly explain the lamp, Figure 3 As shown, this document describes a preferred embodiment of a lamp in accordance with the present invention, which includes an optical component 100, a light source board 200, a circuit board 300, an electrical box 400, a lamp body 500, a power cord 600, a front ring 700, a dust cover 800, and a reflector 900. The optical component 100, the light source board 200, and the circuit board 300 are assembled into the aforementioned quick-install optical module. The lamp body 500 is placed in the electrical box 400. The quick-install optical module is installed into the electrical box 400 from the front end and is mounted on the lamp body 500 by screws. The power cord 600 electrically connects the quick-install light source module to an external power source. The reflector 900 is embedded from the front end of the electrical box 400. The dust cover 800 is mounted on the front end of the electrical box 400 through the front ring 700 to seal the interior of the electrical box 400. In other embodiments, the lamp is not limited to a downlight, but can also be a stage light, a spotlight, etc.
