[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0034] Example
[0035] In this embodiment, the upper part refers to the direction close to the light source board. This is only for the convenience of explanation and is not intended to limit the scope of the application.
[0036] See Figures 1 to 6 As shown, a snap-on downlight structure with an adjustable lens includes a heat sink 2 with a lamp cavity 1. A light source plate 3 is fixed on the top wall of the lamp cavity. In this embodiment, the heat sink and the light source plate are conventional structures of the prior art, and are simply applied. A power cord connected to the light source plate is provided on the heat sink.
[0037] In this embodiment, the upper part of the inner wall of the lamp cavity is integrally formed with several convex surfaces 4, and the inner wall of the convex surfaces is integrally formed with C-shaped locking protrusions 5. The height of the convex surfaces can be processed and set as needed, and the depth of the recessed area of the C-shaped locking protrusions can be processed and set according to different situations. It is mainly used for snap-fit connection of adjustable lens structure. In this embodiment, the number of convex surfaces is two or three. Two-point or three-point positioning is used to ensure the stability and reliability of the connection.
[0038] In practical applications, the lower part of the inner wall of the lamp cavity is integrally formed with several I-shaped protrusions 6, and the I-shaped protrusions are on the same ring; the height of the I-shaped protrusions can be processed and set as needed, and they are mainly used for snapping and positioning the lamp cup.
[0039] The upper part of the lamp cavity is provided with an adjustable lens structure 7, the edge of which is snapped into the recessed area of the C-shaped locking protrusion. The lower part of the lamp cavity is provided with a lamp cup 8, and the symmetrical edges of the lamp cup are integrally formed with snap-fit ears 9, which are provided with snap-fit protrusions 12. The snap-fit protrusions of the snap-fit ears are engaged and positioned with the straight protrusions. An adjustment gap is provided between the adjustable lens structure and the light source plate. The distance of the adjustment gap can be set as needed, so that the adjustment effectiveness and reliability can be guaranteed when the adjustable lens structure is adjusted under the action of external force. The light from the light source plate passes through the adjustable lens structure and shines outward from the lamp cup.
[0040] In this embodiment, the adjustable lens structure includes a limiting ring 71 and a frustum-shaped lens seat 72, with a lens body 73 fixed inside the frustum-shaped lens seat. The inner wall of the limiting ring is a hemispherical inner wall with a larger diameter at the upper end and a smaller diameter at the lower end. The inner wall of the limiting ring is fitted to the outer surface of the frustum-shaped lens seat, and several buffer axial grooves 74 are provided on the top of the side wall of the limiting ring. The buffer axial grooves have a buffering effect, so that when the frustum-shaped lens seat is adjusted in all directions, the buffer axial grooves deform within a certain range, thereby ensuring the friction between the two and realizing a stable and reliable adjustment position of the frustum-shaped lens seat.
[0041] Furthermore, the outer wall of the limiting ring is provided with a limiting protrusion 75 that mates with the C-shaped locking protrusion; the small-diameter end of the frustum-shaped lens seat is inserted into the large-diameter end of the limiting ring, and the frustum-shaped lens seat can be adjusted omnidirectionally within the limiting ring when pressed by external force; the limiting ring is engaged in the lamp cavity, and the limiting protrusion is engaged in the recessed area of the C-shaped locking protrusion for positioning. The number of limiting protrusions matches the number of convex surfaces. Both the lamp cup and the limiting ring are plastic structures. Being plastic allows for deformation within a certain range, ensuring the stability and reliability of assembly, while also maintaining friction with the frustum-shaped lens seat.
[0042] In practical applications, the upper part of the inner wall of the limiting ring is provided with several axial arc-shaped ribs 11; the outer wall of the frustum-shaped lens seat presses against the axial arc-shaped ribs. The axial arc-shaped ribs can increase the friction between the lens seat and the frustum-shaped lens seat, thereby ensuring the stability and reliability of the position when adjusting the circular lens seat.
[0043] In practical applications, the large-diameter end of the frustum-shaped lens mount is greater than or equal to the upper diameter of the limiting ring. A retaining ring 10 is fixed at the symmetrical edge of the heat sink. This retaining ring is primarily for positioning during installation; it is a conventional structure in existing technology and is simply applied, therefore it is not described in detail.
[0044] This utility model has positive effects: The structure of this utility model is reasonable. Its adjustable lens structure and lamp cup are snapped into the lamp cavity of the heat sink, thereby improving the convenience and effectiveness of assembly, and also facilitating disassembly and maintenance operations, improving the efficiency of disassembly and assembly, and having strong applicability.
[0045] Furthermore, its adjustable lens structure includes a limiting ring and a frustum-shaped lens mount. The lens body is fixed inside the frustum-shaped lens mount. The small-diameter end of the frustum-shaped lens mount is inserted into the large-diameter end of the limiting ring. When pressed by external force, the frustum-shaped lens mount can be adjusted omnidirectionally within the limiting ring. This allows for manual adjustment of the illumination direction of the lens body as needed to meet different lighting requirements. In addition, the buffer axial groove on the top of the side wall of the limiting ring helps to limit the frustum-shaped lens mount after adjustment, ensuring a stable and reliable position after adjustment and making it highly adaptable.
[0046] The standard parts used in this embodiment can be purchased directly from the market, and the non-standard structural parts described in the instruction manual can also be processed without any doubt based on existing technical common sense. At the same time, the connection methods of each component adopt mature conventional methods in the existing technology, and the machinery, parts and equipment all adopt conventional models in the existing technology, so they will not be described in detail here.
[0047] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all embodiments here. However, these obvious variations or modifications derived from the essential spirit of this utility model still fall within the protection scope of this utility model.
