Description

Technical Field

[0001] This application belongs to the field of lighting design technology, specifically relating to a light source bracket and a lighting fixture. Background Technology

[0002] Lighting fixtures are widely used in various fields. They typically consist of a light source bracket and a light source module, with the module usually fixed within the fixture's housing by the bracket. Related technologies often use threaded connections or adhesive bonding to secure the light source bracket within the housing. However, this installation method requires assembling numerous parts or involves cumbersome steps, making it difficult to efficiently install the light source bracket into the housing. Utility Model Content

[0003] This utility model discloses a light source bracket for a lighting fixture and a lighting fixture, in order to solve the problem that the light source brackets involved in related technologies are difficult to install efficiently.

[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0005] In a first aspect, this application discloses a light source bracket for a lighting fixture, the lighting fixture including a light source bracket and a housing, the light source bracket having a first snap-fit ​​portion, a positioning groove and a heat dissipation surface;

[0006] The first snap-fit ​​portion is distributed on the outer periphery of the light source bracket and is arranged around the positioning groove. The heat dissipation surface is located on the outer bottom wall of the positioning groove. The first snap-fit ​​portion is used to snap-fit ​​with the second snap-fit ​​portion of the housing to fix the light source bracket in the inner cavity of the housing. The positioning groove is used to accommodate the light source module. The light source bracket is used to conduct heat to the housing through the heat dissipation surface to transfer the heat of the light source module to the housing.

[0007] Secondly, this application discloses a lighting fixture, which includes a light source module, a housing, and the light source bracket mentioned above. The housing has an inner cavity, an opening, and a second snap-fit ​​portion. The inner cavity communicates with the external environment of the housing through the opening.

[0008] The second snap-fit ​​part is provided on the inner wall of the inner cavity. The light source bracket is fixed in the inner cavity by the snap-fit ​​cooperation between the first snap-fit ​​part and the second snap-fit ​​part. The light source module is provided in the positioning groove. The groove opening of the positioning groove is opposite to the opening. The light source bracket is thermally connected to the housing through the heat dissipation surface.

[0009] The technical solution adopted in this utility model can achieve the following technical effects:

[0010] The light source bracket disclosed in this application improves the structure of the light source bracket involved in related technologies by setting the light source bracket as a structural component including a first snap-fit ​​portion. This allows the light source bracket to snap into the second snap-fit ​​portion of the lighting fixture housing through the first snap-fit ​​portion, thereby fixing the light source bracket in the inner cavity. This structure avoids the need to set other additional components to fix the light source bracket in the inner cavity of the housing, thereby reducing the operation steps of installing the light source bracket into the inner cavity, enabling the light source bracket to be installed into the inner cavity quickly, and thus improving installation efficiency.

[0011] Meanwhile, in this structure, the heat generated by the light source module during operation can be transferred to the bottom wall of the positioning groove, and then transferred to the housing through the heat dissipation surface. This allows the light source bracket to transfer the heat of the light source module to the housing, thereby dissipating the heat generated by the light source module through the housing. There is no need to set up an additional special heat dissipation structure for heat dissipation, which simplifies the structure and thus simplifies the installation process, thereby improving installation efficiency.

[0012] In addition, after the heat from the light source module is transferred to the housing through the heat dissipation surface of the light source bracket, the housing can directly exchange heat with the cold air in the external environment of the lighting fixture. This structure enables efficient heat dissipation, which facilitates the timely removal of heat transferred to the housing and helps to efficiently dissipate the heat generated by the light source module.

[0013] In addition, the first snap-fit ​​part is distributed on the outer periphery of the light source bracket, which makes it easier for the light source bracket to snap into the second snap-fit ​​part. This helps to reduce the cumbersome process of installing the light source bracket into the inner cavity, thereby improving installation efficiency. Moreover, the first snap-fit ​​part is set around the positioning groove, which can reduce the risk of loosening caused by vibration or other external forces, allowing the light source bracket to be installed into the inner cavity more stably.

[0034] Please refer to Figures 1 to 8 This application discloses a light source bracket 100 for a lighting fixture. The lighting fixture includes a light source bracket 100 and a housing 300. The light source bracket 100 has a first snap-fit ​​portion 110, a positioning groove 120, and a heat dissipation surface 101.

[0035] The first snap-fit ​​portion 110 is used to achieve an efficient connection between the light source bracket 100 and the housing 300. The first snap-fit ​​portion 110 is distributed on the outer periphery of the light source bracket 100 to facilitate engagement with the second snap-fit ​​portion 330 of the housing 300, and the first snap-fit ​​portion 110 is arranged around the positioning groove 120. The first snap-fit ​​portion 110 engages with the second snap-fit ​​portion 330 to fix the light source bracket 100 in the inner cavity 310 of the housing 300, thereby achieving an efficient connection between the light source bracket 100 and the housing 300 through snap-fit ​​engagement.

[0036] The heat dissipation surface 101 is used to achieve a thermally conductive connection between the light source bracket 100 and the housing 300, and the positioning groove 120 is used to accommodate the light source module 200. During operation, the light source module 200 generates heat, which is transferred to the bottom wall of the positioning groove 120. The heat dissipation surface 101 is located on the outer bottom wall of the positioning groove 120. The light source bracket 100 is used to achieve a thermally conductive connection with the housing 300 through the heat dissipation surface 101, thereby transferring the heat from the light source module 200 to the housing 300.

[0037] The light source bracket 100 disclosed in this application improves the structure of the light source bracket 100 involved in related technologies by setting the light source bracket 100 as a structural component including a first snap-fit ​​portion 110. This allows the light source bracket 100 to snap into the second snap-fit ​​portion 330 through the first snap-fit ​​portion 110, thereby fixing the light source bracket 100 in the inner cavity 310. This structure avoids the need for additional components to fix the light source bracket 100 in the inner cavity 310, thereby reducing the number of operation steps for installing the light source bracket 100 into the inner cavity 310, enabling the light source bracket 100 to be installed into the inner cavity 310 quickly, and thus improving installation efficiency.

[0038] Meanwhile, in this structure, the heat generated by the light source module 200 during operation can be transferred to the bottom wall of the positioning groove 120, and then transferred to the housing 300 through the heat dissipation surface 101. This allows the light source bracket 100 to transfer the heat of the light source module 200 to the housing 300, thereby dissipating the heat generated by the light source module 200 through the housing 300. This eliminates the need for an additional dedicated heat dissipation structure, simplifying the structure and thus simplifying the installation process, which in turn improves installation efficiency.

[0039] In addition, after the heat from the light source module 200 is transferred to the housing 300 through the heat dissipation surface 101, the housing 300 can directly exchange heat with the cold air in the external environment of the lighting fixture. This structure enables efficient heat dissipation, which facilitates the timely removal of heat transferred to the housing 300 and helps to efficiently dissipate the heat generated by the light source module 200.

[0040] In addition, the first snap-fit ​​portion 110 is distributed on the outer periphery of the light source bracket 100, which makes it easier for the light source bracket 100 to snap into the second snap-fit ​​portion 330. This helps to reduce the complexity of installing the light source bracket 100 into the inner cavity 310, thereby improving installation efficiency. Moreover, the first snap-fit ​​portion 110 is arranged around the positioning groove 120, which can reduce the risk of loosening caused by vibration or other external forces, so that the light source bracket 100 can be installed more stably into the inner cavity 310.

[0041] In a further technical solution, the light source bracket 100 may also include a first latch 130 and a second latch 140. For example... Figure 3 and Figure 4As shown, the first latch 130 and the second latch 140 are the core components of the light source bracket 100 that enable the stable installation of the light source module 200 in the positioning groove 120. The first latch 130 and the second latch 140 can be respectively disposed on the first groove wall 121 and the second groove wall 122 of the positioning groove 120. Both the first latch 130 and the second latch 140 are used to engage with the light source module 200, thereby fixing the light source module 200 in the positioning groove 120.

[0042] Specifically, the first buckle 130 and the second buckle 140 can both be used to press the light source module 200 against the bottom wall of the positioning groove 120, thereby achieving a snap-fit ​​engagement with the light source module 200 to fix the light source module 200.

[0043] As described above, this structure sets the light source bracket 100 as a structural component including a first buckle 130 and a second buckle 140. By setting the first buckle 130 and the second buckle 140 on the first groove wall 121 and the second groove wall 122 respectively, the first buckle 130 and the second buckle 140 can be engaged with the light source module 200. This allows the light source module 200 to be fixed in the positioning groove 120 by snapping, avoiding the need for additional components to fix the light source module 200 in the positioning groove 120. It also reduces the number of steps required to install the light source module 200 into the light source bracket 100, thereby improving installation efficiency.

[0044] Optionally, in one embodiment, the first groove wall 121 and the second groove wall 122 can be two opposite side walls within the positioning groove 120, that is, the first groove wall 121 and the second groove wall 122 can both be side walls within the positioning groove 120 and can be distributed relative to each other, so that the first buckle 130 and the second buckle 140 can be used to engage with the opposite edge of the light source module 200 respectively.

[0045] In this structure, since the first latch 130 and the second latch 140 can engage with the opposite edges of the light source module 200 respectively, the first latch 130 and the second latch 140 can fix the light source module 200 more evenly, thereby reducing local stress concentration and helping to improve the reliability and durability of the light source bracket 100.

[0046] In another embodiment, the first groove wall 121 and the second groove wall 122 can be two adjacent side walls within the positioning groove 120, that is, the first groove wall 121 and the second groove wall 122 can both be side walls within the positioning groove 120 and can be adjacent, so that the first buckle 130 and the second buckle 140 can be used to engage with the edge adjacent to the light source module 200 respectively.

[0047] In this structure, since the first latch 130 and the second latch 140 are distributed on two adjacent side walls within the positioning groove 120, the light source module 200 can be easily removed from the positioning groove 120, thereby facilitating the maintenance and replacement of the light source module 200.

[0048] In order to facilitate the installation of the light source module 200 into the positioning groove 120, in one embodiment, the first groove wall 121 may be provided with a first clearance hole 102. The first clearance hole 102 and the first buckle 130 may be distributed along the groove opening of the positioning groove 120. The first clearance hole 102 is used to avoid the deformation of the first buckle 130 during the engagement with the light source module 200, thereby making the first buckle 130 easier to deform, so as to facilitate the installation and removal of the light source module 200.

[0049] In another embodiment, the second groove wall 122 may be provided with a second clearance hole. The second clearance hole and the second buckle 140 may be distributed along the groove opening of the positioning groove 120. The second clearance hole can be used to avoid the deformation generated during the engagement of the second buckle 140 and the light source module 200, thereby making the second buckle 140 easier to deform and making the light source module 200 easier to install or remove.

[0050] Of course, in other embodiments, the first groove wall 121 may be provided with a first clearance hole 102, and the second groove wall 122 may be provided with a second clearance hole. The first clearance hole 102 and the first buckle 130 may be distributed along the groove opening of the positioning groove 120, and the second clearance hole and the second buckle 140 may be distributed along the groove opening of the positioning groove 120. The first clearance hole 102 may be used to avoid the deformation of the first buckle 130 during the engagement with the light source module 200, and the second clearance hole may be used to avoid the deformation of the second buckle 140 during the engagement with the light source module 200. This structure makes it easier for both the first buckle 130 and the second buckle 140 to deform, thereby making it easier to install and remove the light source module 200.

[0051] In the embodiments of this application, such as Figures 3 to 5 As shown, the light source bracket 100 may be provided with a third clearance hole 150, and the first groove wall 121 may be provided with a first clearance groove 103. The first clearance groove 103 and the third clearance hole 150 may both be connected to the positioning groove 120. The first clearance groove 103 may be connected to the third clearance hole 150. The third clearance hole 150 may be connected to the positioning groove 120 through the first clearance groove 103. Of course, the third clearance hole 150 may also be directly connected to the positioning groove 120.

[0052] Both the third clearance hole 150 and the first clearance groove 103 are used to avoid the electrical connectors of the light source module 200, allowing the electrical connectors to pass through the third clearance hole 150 and the first clearance groove 103 and extend into the positioning groove 120 for electrical connection with the light source module 200. This structure avoids an overly cluttered arrangement of electrical connectors, making the arrangement more orderly, thus facilitating inspection or replacement of electrical connectors and reducing maintenance difficulty.

[0053] In addition, please refer to Figure 3 and Figure 8 The circuit board 210 described below may include an electrical connection portion 211. The electrical connector can achieve electrical connection with the circuit board 210 through the electrical connection portion 211. Specifically, the electrical connector may be a wire or a flexible circuit board, and the circuit board 210 may be a printed circuit board or a flexible circuit board. The embodiments of this application do not limit the specific types of electrical connectors and circuit boards 210.

[0054] Please continue to refer to this. Figure 3 and Figure 8 In order to avoid the circuit board 210 blocking the third clearance hole 150, which could easily affect the layout of electrical connectors, the circuit board 210 may be provided with a second clearance groove 212 to avoid the third clearance hole 150, thereby facilitating the layout of electrical connectors.

[0055] To securely fix the light source module 200, multiple first latches 130 can be provided, and these latches 130 can be distributed on opposite sides of the first clearance groove 103 along a direction perpendicular to the opening of the positioning groove 120. This structure, by providing multiple first latches 130, allows for engagement with multiple parts of the light source module 200, thereby securing the light source module 200 more stably and making it more stable. Simultaneously, the multiple first latches 130 can evenly apply force to the light source module 200, preventing excessive stress concentration that could easily damage it.

[0056] Please refer to Figure 2 and Figure 7 Based on the light source bracket 100 disclosed in the embodiments of this application, the embodiments of this application further disclose a lighting fixture, which includes a light source module 200, a housing 300 and the light source bracket 100 as described in any of the above embodiments.

[0057] The housing 300 has an inner cavity 310, an opening 320, and a second snap-fit ​​portion 330. The inner cavity 310 is connected to the external environment of the housing 300 through the opening 320, so that the light emitted by the light source module 200 can pass through the positioning groove 120 and the opening 320 in sequence and be projected into the external environment of the housing 300.

[0058] The second snap-fit ​​portion 330 is provided on the inner wall of the inner cavity 310. The light source bracket 100 is fixed in the inner cavity 310 through the snap-fit ​​engagement between the first snap-fit ​​portion 110 and the second snap-fit ​​portion 330. The light source module 200 is provided in the positioning groove 120, so that the light source module 200 can be fixed in the inner cavity 310 through the light source bracket 100. The groove of the positioning groove 120 is opposite to the opening 320, so that the light emitted by the light source module 200 can be projected into the external environment. The light source bracket 100 is thermally connected to the housing 300 through the heat dissipation surface 101 to transfer the heat of the light source module 200 to the housing 300.

[0059] In this structure, the light source bracket 100 is fixed in the inner cavity 310 by a snap-fit ​​mechanism, which avoids the need for additional components to fix the light source bracket 100 in the inner cavity 310. This reduces the number of installation steps for installing the light source bracket 100 into the inner cavity 310, allowing the light source bracket 100 to be installed into the inner cavity 310 quickly, thereby improving installation efficiency.

[0060] In feasible technical solutions, the lighting fixture may also include a heat spreader 400, which may be disposed in the inner cavity 310 and connected to the housing 300. The light source bracket 100 may be disposed on the side of the heat spreader 400 facing the opening 320. The light source bracket 100 may be an insulated heat-conducting bracket, and the heat dissipation surface 101 may be connected to the heat spreader 400 so that the light source bracket 100 can be thermally connected to the heat spreader 400 through the heat dissipation surface 101.

[0061] Specifically, the materials of the housing 300 and the heat spreader 400 can be metal, alloy, etc., and the materials of the insulating heat-conducting bracket can be plastic, ceramic, etc. The embodiments of this application do not limit the materials of the housing 300, the heat spreader 400 and the insulating heat-conducting bracket.

[0062] During the actual operation, the light source module 200 generates heat. The light source module 200 is mounted on an insulating heat-conducting bracket, so that the heat generated by the light source module 200 can be transferred to the insulating heat-conducting bracket and then transferred to the heat dissipation surface 101 of the insulating heat-conducting bracket to the heat spreader 400. The heat spreader 400 is connected to the housing 300, so that the heat transferred to the heat spreader 400 can be transferred to the housing 300.

[0063] In other words, the heat generated by the light source module 200 can be transferred to the housing 300 through the insulating heat-conducting bracket and the heat spreader 400, thereby dissipating the heat to the external environment of the lighting fixture through the housing 300. The housing 300 can directly exchange heat with the cold air in the external environment of the lighting fixture, making heat dissipation relatively efficient. Simultaneously, the insulating heat-conducting bracket isolates the light source module 200 from the housing 300, preventing electrical conduction between them. This prevents the housing 300 from becoming conductive, thus avoiding accidents such as electric shock during the installation and removal of the lighting fixture by engineers, and ultimately reducing the safety risks associated with the lighting fixture.

[0064] To further improve heat dissipation, the lighting fixture may also include a first heat-conducting component and a second heat-conducting component. Both components may be disposed within the inner cavity 310. The first heat-conducting component may be located between the heat spreader 400 and the heat dissipation surface 101, and may be connected to both. The second heat-conducting component may be located between the light source module 200 and the insulating heat-conducting bracket, and may be connected to both. Specifically, both the first and second heat-conducting components may be made of silicone, silicone grease, or polyurethane; this embodiment does not impose any limitations on these materials.

[0065] This structure allows for more efficient heat transfer between the insulating heat-conducting bracket and the heat spreader 400, and more efficient heat transfer between the light source module 200 and the insulating heat-conducting bracket. This reduces heat loss between the insulating heat-conducting bracket and the heat spreader 400, and between the light source module 200 and the insulating heat-conducting bracket. Consequently, the heat generated by the light source module 200 can be dissipated more efficiently to the external environment of the lighting fixture, further improving the heat dissipation effect.

[0066] Please refer to Figures 2 to 5 as well as Figure 7 To facilitate the installation of the light source bracket 100, the heat spreader 400 may be provided with a positioning hole 410, and the light source bracket 100 may be provided with a third clearance hole 150. The side of the light source bracket 100 facing the heat spreader 400 may have a first protrusion 160 distributed around the third clearance hole 150. The first protrusion 160 may be positioned in the positioning hole 410, and the third clearance hole 150 may communicate with the positioning groove 120. The third clearance hole 150 may be used to avoid the electrical connector of the electrical connection light source module 200.

[0067] This structure allows for the rapid determination of the installation position of the light source bracket 100 during installation into the inner cavity 310 via the positioning engagement between the first protrusion 160 and the positioning hole 410, thus facilitating the installation of the light source bracket 100. Simultaneously, this structure facilitates the alignment of the third clearance hole 150 with the positioning hole 410, allowing the electrical connector to pass through the space enclosed by the first protrusion 160 and the third clearance hole 150 to extend into the positioning groove 120, thereby enabling electrical connection with the light source module 200 in the positioning groove 120.

[0068] Of course, if the first groove wall 121 can be provided with a first clearance groove 103, this structure can facilitate the electrical connector to pass through the space enclosed by the first protrusion 160, the third clearance hole 150 and the first clearance groove 103 and extend into the positioning groove 120, thereby electrically connecting with the light source module 200 in the positioning groove 120.

[0069] In a feasible technical solution, such as Figures 2 to 7 As shown, the lighting fixture may also include a lens 500 and a connector 600, both of which may be located within the inner cavity 310. The inner wall of the inner cavity 310 may be provided with a third snap-fit ​​portion 340. The connector 600 may include a fourth snap-fit ​​portion 610 and a light-transmitting hole 620. The connector 600 can be fixed to the inner cavity 310 through the snap-fit ​​engagement between the fourth snap-fit ​​portion 610 and the third snap-fit ​​portion 340.

[0070] This structure allows the lens 500 to be clamped and fixed between the light source bracket 100 and the connector 600, thereby securing the lens 500 within the inner cavity 310. This enables reliable positioning of the lens 500 along its optical axis, controlling its focal length and allowing for stable adjustment of the light emitted by the light source module 200. Optionally, the connector 600 can be an annular structure, and the housing 300 can be a cylindrical structure, facilitating assembly between the connector 600 and the housing 300. This structure is also easy to manufacture, reducing costs.

[0071] Meanwhile, the lens 500 can be positioned opposite the light-transmitting hole 620 and the positioning groove 120 respectively, so that the light emitted by the light source module 200 can pass through the lens 500, the light-transmitting hole 620 and the opening 320 in sequence and be projected into the external environment of the housing 300 to achieve the lighting function.

[0072] In this structure, since the connector 600 is fixed to the inner cavity 310 through the snap-fit ​​between the fourth snap-fit ​​part 610 and the third snap-fit ​​part 340, it is possible to avoid setting additional components to fix the connector 600 in the inner cavity 310, so that the connector 600 can be quickly installed into the inner cavity 310, thereby improving the installation efficiency of the lighting fixture.

[0073] Furthermore, since the light source module 200 is installed into the light source bracket 100 by snap-fit, and the light source bracket 100 and the connector 600 are also installed into the inner cavity 310 by snap-fit, and the light source bracket 100, lens 500 and connector 600 are distributed in the inner cavity 310 in sequence from the direction away from the opening 320 to the direction closer to the opening 320, the assembly process of the lighting fixture is relatively simple and efficient, and it is easy to realize automated assembly, which is conducive to further improving the installation efficiency.

[0074] Preferably, the aperture of the light-transmitting hole 620 can increase from the direction away from the opening 320 to the direction closer to the opening 320, thereby facilitating the projection of the light emitted by the light source module 200 into the external environment of the housing 300. The inner wall of the light-transmitting hole 620 can have a dimming part 621 to adjust the light emitted through the light-transmitting hole 620 to the outside of the housing 300.

[0075] Specifically, the dimming unit 621 can be a dimming pattern, such as a diffuse reflection layer, which can scatter light through the dimming pattern, reducing the intensity of light directly entering the human eye, thus reducing glare and improving visual comfort. Of course, the dimming unit 621 can also be a dimming film, such as a silver film or an aluminum film, which can effectively reflect light, reduce light loss, and improve the overall brightness and efficiency of the lighting fixture.

[0076] In a further technical solution, the lens 500 may include a lens body 510 and a flange 520. The flange 520 may extend around the optical axis of the lens body 510 and may be connected to the end of the lens body 510 facing the connector 600. The light source support 100 may also include a first positioning rib 170, and the end face of the light-transmitting hole 620 facing the light source support 100 may be provided with a second protrusion 630. The first positioning rib 170 and the second protrusion 630 may respectively abut against the two opposite sides of the flange 520 distributed along the optical axis of the lens body 510, so as to clamp and fix the lens 500 between the light source support 100 and the connector 600. It should be noted that the optical axis of the lens body 510 is the same as the optical axis of the lens 500.

[0077] In this structure, the flange 520 has a more regular shape relative to the lens body 510, making it easier to be clamped and fixed by the first positioning rib 170 and the second protrusion 630. This reduces the risk of lens 500 displacement after the lighting fixture is impacted, thus improving the stability of the lighting fixture. Furthermore, the first positioning rib 170 saves material, thereby reducing costs. In addition, the second protrusion 630 creates a receiving space between the lens body 510 and the connector 600, allowing those skilled in the art to install filters or diffusers within this space according to actual needs, thereby achieving different lighting effects.

[0078] Among the available technical solutions, such as Figures 3 to 5 As shown, there can be multiple first positioning ribs 170, which can be spaced around the lens body 510 at intervals. These ribs restrict the movement of the lens 500 along a direction perpendicular to its optical axis. Furthermore, each first positioning rib 170 can abut against the lens body 510 along a direction perpendicular to its optical axis, thus making the lens 500 more stably fixed. The multiple first positioning ribs 170 can be evenly distributed around the lens body 510 at intervals to ensure uniform contact with the lens 500 and minimize stress concentration.

[0079] Of course, such as Figure 6 As shown, there can be multiple second protrusions 630. These multiple second protrusions 630 can be distributed at intervals on the end face of the light-transmitting hole 620 facing the light source support 100. This allows the flange 520 to be clamped more stably through the cooperation between the multiple second protrusions 630 and the multiple first positioning ribs 170, which helps to improve the stability of the lens 500 in its optical axis direction.

[0080] Furthermore, the connector 600 may also include a plurality of mutually spaced second positioning ribs 640, which may be distributed around the flange 520. The plurality of second positioning ribs 640 and the plurality of second protrusions 630 may be evenly distributed around the flange 520 at intervals, so as to uniformly contact the lens 500 and avoid stress concentration as much as possible.

[0081] Multiple second positioning ribs 640 can be connected to multiple second protrusions 630 respectively, thereby improving the overall strength of the connector 600. Furthermore, the multiple second positioning ribs 640 can respectively abut against the flange 520 in a direction perpendicular to the optical axis of the lens body 510. In this structure, the contact between the multiple second positioning ribs 640 and the flange 520 is surface contact, resulting in a larger contact area between the second positioning ribs 640 and the flange 520. This further and more stably restricts the movement of the lens 500 along a direction perpendicular to its (i.e., the lens 500's) optical axis.

[0082] In one embodiment, such as Figures 3 to 7 As shown, the second snap-fit ​​portion 330 can be a first annular slot, the third snap-fit ​​portion 340 can be a second annular slot, the first snap-fit ​​portion 110 can be a third buckle, and there can be multiple third buckles, which can be snapped into the first annular slot respectively. The fourth snap-fit ​​portion 610 can be a fourth buckle, and there can be multiple fourth buckles, which can be snapped into the second annular slot respectively. This structure helps to reduce production difficulty, and the third buckle and the first annular slot and the fourth buckle and the second annular slot are easy to cooperate, which helps to reduce assembly difficulty.

[0083] Of course, in other embodiments, the second snap-fit ​​portion 330 may include a plurality of first snap-fit ​​slots, and the third snap-fit ​​portion 340 may include a plurality of second snap-fit ​​slots. In this case, the plurality of third snap-fits may engage with the plurality of first snap-fit ​​slots respectively, and the plurality of fourth snap-fits may engage with the plurality of second snap-fit ​​slots respectively. This structure can reduce the area of ​​the snap-fit ​​slots on the inner wall of the inner cavity 310, thereby helping to increase the overall strength of the housing 300.

[0084] Furthermore, to ensure uniform force distribution, multiple third latches can be evenly distributed at intervals on the outer periphery of the light source bracket 100, multiple fourth latches can be evenly distributed at intervals around the central axis of the light-transmitting aperture 620, multiple first slots can be evenly distributed at intervals around the optical axis of the lens 500, and multiple second slots can be evenly distributed at intervals around the optical axis of the lens 500. It should be noted that the central axis of the light-transmitting aperture 620 can be parallel to the optical axis of the lens 500.

[0085] In the embodiments of this application, such as Figure 3 and Figure 8As shown, the light source module 200 may include a circuit board 210 and a light source body 220. The circuit board 210 may be disposed in the positioning groove 120, and the light source body 220 may be disposed on the side of the circuit board 210 facing the groove 120. The light source body 220 may be electrically connected to the circuit board 210, so that the electrical connector can supply power to the light source body 220 through the circuit board 210. The light source body 220 may be opposite to the lens body 510, so that the light emitted by the light source body 220 can pass through the lens 500, the light-transmitting hole 620, and the opening 320 and be projected into the external environment of the housing 300. The first latch 130 and the second latch 140 may respectively engage with the circuit board 210 to fix the circuit board 210 in the positioning groove 120.

[0086] Specifically, the light source body 220 can be an LED lamp bead or a halogen lamp bead, and this application embodiment does not limit this. Among them, when the light source body 220 is an LED lamp bead, the light source module 200 can be a COB (Chip On Board, high power integrated surface) light source.

[0087] In one of the alternative technical solutions, such as Figure 2 As shown, the lighting fixture may further include a light reflector 700, which may be disposed in the inner cavity 310. The light reflector 700 may be located between the flange 520 and the circuit board 210, and the light reflector 700 may surround at least a portion of the light source body 220 and at least a portion of the lens body 510, thereby optimizing the directionality and uniformity of light, which is beneficial to improving the luminous efficacy and uniformity of light distribution of the lighting fixture. Specifically, the light reflector 700 may be a diffuse reflector, a specular reflector, or a metal reflective film, and the embodiments of this application do not limit this.

[0088] In further technical solutions, such as Figure 1 As shown, the lighting fixture may also include a power supply box 800, which can be connected to the housing 300 for controlling the light source module 200.

[0089] The lighting fixtures disclosed in this application can be high-voltage track spotlights or spotlights, etc., and this application does not limit the specific type of lighting fixture.
