[0008] Furthermore, the limiting structure includes an elongated base and a limiting boss provided on the base. The module bracket is provided with a locking tooth that is adapted to the limiting boss, and the locking tooth engages with the limiting boss on the base.
[0009] Furthermore, the first connection structure includes an L-shaped first hook, the opening of which faces the circumferential direction of the outer contour of the module bracket; the optical component is correspondingly provided with a first connecting post, and rotating the module bracket causes the first hook to grip or disengage from the first connecting post.
[0010] Furthermore, the optical component is provided with a positioning groove, and the first connecting post protrudes from the inner wall of the positioning groove toward the first connecting structure.
[0011] Furthermore, the first connection structure also includes a limiting post, which extends from the outer edge of the module bracket toward the positioning groove, and the opening of the first hook faces the limiting post.

[0035] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.
[0036] In the description of this application, it should be noted that the terms "upper," "lower," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present invention. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.
[0037] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "assembly," and "connection" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.
[0038] In the description of this application, the term "multiple" means at least two, such as two, three or more, unless otherwise expressly and specifically defined.
[0039] This application discloses an optical module.
[0040] Please refer to Figure 1-5 In one embodiment of this application, an optical module includes an optical component 2 and a module bracket 1. The optical component 2 is an integrated unit of a light source and a lens, modularly disposed within a luminaire to provide illumination. The optical component 2 is generally frustum-shaped, with its smaller end face close to a conductive plate within the luminaire to provide circuit support, and its larger end face serving as an illumination surface to provide an illumination area. The module bracket 1 is a cylindrical sleeve adapted to the optical component 2, with a first connecting structure and a second connecting structure on its outer edge. The optical component 2 can be rotatably connected to the module bracket 1 through the first connecting structure, and the module bracket 1 can be detachably rotatably connected to the luminaire body through the second connecting structure. When the optical component 2 needs to be replaced, the entire optical module is first unscrewed from the luminaire body, then the optical component 2 is disassembled from the module bracket 1 by rotation, and finally the new optical component 2 is reassembled into the luminaire body along the original path, thereby achieving quick replacement of the optical module.
[0041] The lower part of the module bracket 1 is an outwardly extending overlapping portion that can overlap with the lamp body to achieve the enclosure of the lamp body. The upper surface, as shown in the figure, overlaps with the lower surface of the optical component 2. The first connecting structure is set as follows... Figure 2The upper surface of the module bracket 1 shown includes an L-shaped first hook 3, which is a flat hook arranged along the circumference of the module bracket 1 with its opening facing the circumference. The optical component 2 is correspondingly provided with a first connecting post 4, which engages within the first hook 3. Rotating the optical component 2 or the module bracket 1 will cause the first hook 3 to engage or disengage from the first connecting post 4, thus enabling the installation and removal of the optical component 2 and the module bracket 1. The second connecting structure is a C-shaped second hook 5, which is also a flat hook arranged along the circumference of the module bracket 1, with the first hook 3 and the second hook 5 facing the same direction. A corresponding second connecting post (not shown in the figure) is provided within the lamp body, which engages within the second hook 5. Rotating the module bracket 1 will cause the second hook 5 to engage or disengage from the second connecting post, thus enabling the installation and removal of the module bracket 1 and the lamp body. To avoid interference between the rotation between the optical component 2 and the module bracket 1 and the rotation between the module bracket 1 and the lamp body, preferably, the first hook 3 and the second hook 5 are located on the circumferences of different diameters of the module bracket 1.
[0042] In an optional embodiment of this application, the optical component 2 may be provided with a positioning groove 6, which is formed by protruding outward from the circumference of the optical component 2. The first connecting post 4 extends from the inner wall of the positioning groove 6 toward the first hook 3, and the first hook 3 engages with the first connecting post 4 inside the positioning groove 6. By rotating the module bracket 1, the first hook 3 gradually disengages from the first connecting post 4 and slides within the positioning groove 6, then abuts against the side wall of the positioning groove 6. Finally, the first hook 3 is pulled out of the positioning groove 6 to separate the module bracket 1 from the optical component 2. When it is necessary to reassemble the optical component 2 and the module bracket 1, the first hook 3 is inserted close to the side wall of the positioning groove 6, and the module bracket 1 is rotated so that the first hook 3 slides within the positioning groove 6 and finally grips the first connecting post 4, thereby connecting the optical component 2 and the module bracket 1. Understandably, the positioning groove 6 can not only guide the insertion of the first hook 3 and the smooth connection with the first connecting post 4, ensuring that the optical module can be accurately connected to the module bracket 1, thus playing a certain positioning role; at the same time, it can also limit the sliding of the first hook 3 in the positioning groove 6, thereby limiting the rotation between the optical component 2 and the module bracket 1, avoiding excessive rotation from hindering other functional components of the optical component 2 or the module bracket 1, thus playing a certain limiting function.
[0043] Furthermore, the first connecting structure also includes a limiting post 7 extending from the upper end of the module bracket 1 towards the positioning groove 6. The opening of the first hook 3 faces the limiting post 7, and the circumferential distance between the first hook 3 and the limiting post 7 does not exceed the circumferential length of the positioning groove 6. That is, when the optical component 2 and the module bracket 1 are connected, both the first hook 3 and the limiting post 7 are located within the positioning groove 6; when the module bracket 1 is rotated, the first hook 3 gradually disengages from the first connecting post 4, while the limiting post 7 gradually approaches the first connecting post 4 and eventually abuts against it. The setting of the limiting post 7, based on the limitation of the positioning groove 6, further restricts the rotation between the module bracket 1 and the optical component 2.
[0044] Furthermore, the distance L1 between the first connecting post 4 and the side wall of the positioning groove 6 is equal to the length L2 of the first hook 3. That is, when the first hook 3 disengages from the first connecting post 4, the side wall of the first hook 3 abuts against the side wall of the positioning groove 6. This arrangement reduces rotation time, allowing for faster assembly of the optical component 2 and the module bracket 1. Furthermore, the distance L3 between the limiting post 7 and the first hook 3 can be equal to the distance L1 between the first connecting post 4 and the side wall of the positioning groove 6 plus the diameter of the first connecting post 4. This means that when the first hook 3 disengages from the first connecting post 4, the side wall of the first hook 3 abuts against the side wall of the positioning groove 6, and the limiting post 7 abuts against the first connecting post 4. When assembling the optical component 2 with the module bracket 1, the side wall of the first hook 3 can be inserted against the side wall of the positioning groove 6, and the limiting post 7 can also be inserted against the first connecting post 4, further ensuring the accuracy of the connection between the optical component 2 and the module bracket 1, saving assembly time, and enabling rapid replacement of the optical component 2. Furthermore, the distance L4 from the first connecting post 4 to the other side wall of the positioning groove 6 is not less than the distance L3 between the limiting post 7 and the first hook 3, so as to make room for the movement of the limiting post 7 in the positioning groove 6, and to ensure that the first hook 3 is rotatably connected to the first connecting post 4 in the positioning groove 6.
[0045] Based on the above configuration, in an optional embodiment, the optical component 2 may be provided with a protrusion 13, which is located near the positioning groove 6. When the module bracket 1 is rotated, the second hook 5 abuts against the protrusion 13 as the module bracket 1 rotates.
[0046] Furthermore, to further improve the reliability of the connection between the optical component 2 and the module bracket 1, multiple first connection structures can be provided and evenly spaced on the module bracket 1. In such a case... Figure 2-5In the illustrated embodiment, there are three first connecting structures. Correspondingly, there are three positioning slots 6 and three first connecting posts 4, each corresponding to one of the first connecting structures. These are also evenly spaced on the optical component 2 to ensure uniform force distribution in all directions after assembly of the optical component 2 and the module support 1, thereby increasing the robustness of the optical module. It is understood that the number of first connecting structures can be determined according to actual needs, and this application does not limit this number.
[0047] During the disassembly of the optical module from the lamp body, the optical component 2 and the module bracket 1 may separate. To avoid this, in an optional embodiment, the optical component 2 may also be provided with a limiting structure 8 arranged along its circumference. As shown in the figure, the limiting structure 8 includes an elongated base 9, the lower end face of which is flush with the lower end face of the optical component 2; and a limiting boss 10, which faces the module bracket 1 from the lower end face of the base 9 with a locking tooth 11. Correspondingly, the upper end face of the module bracket 1 is provided with a locking tooth 11 corresponding to the limiting boss 10. When the first hook 3 grips the first connecting post 4, the limiting boss 10 engages with the locking tooth 11. When the optical module is rotated, the second hook 5 disengages from the second connecting post, and the module bracket 1 is removed from the lamp body. Since the openings of the first hook 3 and the second hook 5 face the same direction, the first hook 3 will also disengage from the first connecting post 4 due to the rotation of the module bracket 1. The rotation between the optical component 2 and the module bracket 1 is restricted by the limiting structure 8 and the paired teeth 11, thus allowing the optical component 2 and the module bracket 1 to be removed from the lamp body as a single module. In actual use, by holding the optical component 2 and rotating the module bracket 1 forcefully, the teeth 11 on the module bracket 1 will pass over the limiting boss 10 under the action of external force, releasing the rotation restriction between the optical component 2 and the module bracket 1. Then, the first connecting structure enables the disassembly and assembly of the optical component 2 and the module bracket 1.
[0048] Furthermore, both the limiting boss 10 and the locking teeth 11 on the module bracket 1 are semi-cylinders, allowing the locking teeth 11 on the module bracket 1 to smoothly pass over the limiting boss 10 under external force. In an optional embodiment, the limiting boss 10 and the locking teeth 11 on the module bracket 1 can be made of elastic material. To further ensure rotational restriction between the optical component 2 and the module bracket 1, multiple limiting structures 8 can be provided, such as... Figure 2-5 In the illustrated embodiment, there are three limiting structures 8, each located close to one of the three positioning slots 6. To avoid obstructing rotation between the module bracket 1 and the lamp body, the limiting structures 8 can be located on the same diameter circumference as the first connecting structure on the module bracket 1.
[0049] Furthermore, the optical component 2 can be provided with a gripping part 12 to better grip and apply force, causing the locking teeth 11 on the module bracket 1 to pass over the limiting boss 10, thereby realizing the rotational separation and assembly of the optical component 2 and the module bracket 1. To increase the friction between the hand and the gripping part 12, the surface of the gripping part 12 can be provided with friction texture. Based on this, this application discloses a more preferred embodiment, such as... Figure 3 and Figure 4 As shown, the positioning groove 6 protrudes outward from the optical component 2 to form the gripping part 12 as described above. This arrangement saves the circumferential space of the optical component 2, allowing the connecting components to occupy a relatively large space, thus ensuring the reliability of the connection between the optical component 2 and the module bracket 1.
[0050] In an optional embodiment of this application, the optical component 2 is further provided with heat dissipation holes, which are disposed in the positioning groove 6 to prevent the temperature of the optical component 2 from becoming too high, thereby improving the reliability and service life of the entire lamp.
[0051] This application also discloses a lamp, including a lamp body and an optical module as described above. The lamp body is provided with a second connecting post as described above, and the lamp body and the optical module are detachably connected via a second hook 5 and the second connecting post.
[0052] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
