[0069] Example 1

[0070] The present embodiment provides a waterproof lens and reflective cup assembly structure, which includes a lens assembly 1 and a reflective cup assembly 2 , wherein the lens assembly 1 includes a lens plate 14 and a fixed edge 11 sealed and connected to the lens assembly 1 .

[0071] The fixing edge 11 is a waterproof annular structure, which is arranged in an annular shape at the edge of the lens plate 14 and has a fixing surface 114 protruding from the surface of the lens plate 14. The inner side of the fixing edge 11 can form a groove 12 with the light incident side of the lens plate 14; since the lens plate 14 generally has a good waterproof performance, the fixing edge 11 is sealed and connected to the lens plate 14, so that the lens plate 14 and the fixing edge 11 can enclose a groove 12 with one side being waterproof, such as Figure 8 As shown, the other side of the groove 12 is open and can be used to be assembled and connected with the mounting structure of the lamp to form a waterproof chamber.

[0072] The reflective cup assembly 2 can be located in the groove 12 and assembled and connected with the lens assembly 1. The combined effect of the reflective cup assembly 2 and the lens assembly 1 can improve the optical effect of the lamp to meet the use requirements.

[0073] Preferably, the surface of the fixing edge 11 located on the opening side of the groove 12 is defined as a fixing surface 114 , and an annular waterproof groove 112 is provided on the fixing surface 114 , and a waterproof ring 3 is arranged in the waterproof groove 112 .

[0074] The fixing surface 114 is a side surface of the fixing edge 11 that protrudes from the surface of the lens assembly 1 and is not directly connected to the lens assembly 1 . The waterproof groove 112 is a strip-shaped groove structure that is concave relative to the fixing surface 114 and has a groove bottom and a groove wall.

[0075] The waterproof ring 3 is an annular waterproof component, which preferably has a certain flexibility. When the waterproof ring 3 is installed in the waterproof groove 112, the waterproof ring 3 can be limited by the groove wall to prevent the waterproof ring 3 from swinging left and right. In addition, the seepage length between the waterproof ring 3 and the groove bottom and groove wall is relatively long, and water is not easy to penetrate from the gap between the waterproof ring 3 and the groove bottom and groove wall, which can improve the waterproof effect.

[0076] The waterproof ring 3 partially protrudes from the fixing surface 114, and the protruding portion can abut against the mounting structure of the lamp. During installation, the waterproof ring 3 can be deformed by pressing to improve the sealing effect between the lens assembly and the mounting structure, thereby improving the waterproof effect.

[0077] The present application provides a waterproof lens and reflective cup assembly structure, in which a groove 12 with an opening on one side can be formed by sealingly cooperating between a lens plate 14 and a fixed edge 11. When in use, the lens assembly 1 can be sealed and connected to the mounting structure of the lamp to form a waterproof chamber. The reflective cup assembly 2 can be installed in the waterproof chamber and assembled and connected to the lens assembly 1, thereby further improving the optical effect of the lamp through the cooperation between the lens assembly 1 and the reflective cup assembly 2.

[0078] Providing a waterproof ring 3 on the fixed surface 114 can improve the sealing effect between the lens assembly 1 and the lamp mounting structure. The waterproof groove 112 is a groove-shaped structure, including a groove bottom and a groove wall. Arranging the waterproof ring 3 in the waterproof groove 112 can extend the seepage length between the fixed edge 11 and the waterproof ring 3, further improve the waterproof effect, and prevent the waterproof ring 3 from swinging.

[0079] like Figure 6 As shown, the lens assembly 1 includes a lens optic 13 and a lens plate 14, wherein the lens optic 13 can be used to change the light distribution, and it can be a convex lens, a spotlight lens, etc.; the lens plate 14 is used to connect the lens optic 13, and the lens optic 13 can be fixed by fixing the lens plate 14; preferably, the lens optic 13 and the lens plate 14 are integrally formed; the lens plate 14 can also be integrally formed with the fixed edge 11.

[0080] like Figure 9-10 As shown, the reflector assembly 2 includes a reflector optical cup 23 and a reflector plate 24, wherein the reflector optical cup 23 can be used to change the light distribution, and its shape is similar to a cup shape, with a light incident side and a light emitting side, and the light incident side of the reflector optical cup 23 has a light incident hole 21, and the light emitting side has a light emitting hole; the reflector plate 24 is used to connect the reflector optical cup 23, and the reflector optical cup 23 can be fixed by fixing the reflector plate 24; preferably, the reflector optical cup 23 and the reflector plate 24 are integrally formed.

[0081] The assembly connection of the lens assembly 1 and the reflector assembly 2 is as follows: the lens optics 13 and the reflector optics 23 cooperate with each other, and the light can achieve the required optical effect through the joint action of the lens optics 13 and the reflector optics 23. Preferably, the lens optics 13 and the reflector optics 23 are aligned.

[0082] It is understandable that in some cases, there may be gaps in the lamp mounting structure connected to the lens assembly 1, making it impossible to form a completely sealed chamber. In this case, the waterproof lens and reflective cup assembly structure described in the present application can still provide a relatively good waterproof effect because one side of the structure is waterproof and has an inward groove 12.

[0083] Preferably, the reflective cup assembly 2 is completely located in the groove 12 .

[0084] At this time, the lens assembly 1 can be covered on the plane, and the reflective cup assembly 2 can be located in the cavity formed by the lens assembly 1 and the plane.

[0085] Preferably, the waterproof ring 3 is provided with a first waterproof rib 32 protruding from the fixing surface 114 .

[0086] like Fig.12 As shown, the first waterproof rib 32 is a strip-shaped protrusion. During installation, the first waterproof rib 32 can be compressed and deformed by pressing the waterproof ring 3, thereby filling the gap between the waterproof ring 3 and the lamp installation structure to achieve a sealing and waterproof effect; further preferably, the first waterproof rib 32 and the waterproof ring 3 are integrally formed; the waterproof ring 3 can be made of silicone.

[0087] Preferably, a second waterproof rib 113 protruding from the bottom of the waterproof groove 112 is provided in the waterproof groove 112 .

[0088] like Figure 4-5 As shown, the second waterproof rib 113 is a strip-shaped protrusion protruding from the bottom of the waterproof groove 112. The second waterproof rib 113 can compress and deform the waterproof ring 3 by squeezing the waterproof ring 3, thereby filling the gap between the second waterproof rib 113 and the waterproof ring 3 to achieve a sealing and waterproof effect.

[0089] At the same time, since the second waterproof rib 113 is a convex structure, its side has a relatively concave receiving portion 115. During installation, the receiving portion 115 can accommodate excess colloid after the waterproof ring 3 is deformed, thereby releasing the internal pressure of the waterproof ring 3; the excess colloid is received by the receiving portion 115, which can prevent the lens assembly from being lifted up by the waterproof ring 3, thereby maintaining the stable position of the lens optics 13 and improving the optical accuracy.

[0090] Further preferably, the second waterproof rib 113 is integrally formed with the fixed edge 11 .

[0091] In one or more preferred embodiments, at least two first through holes 111 arranged around the fixed edge 11 are provided on the fixed edge 11 , and at least two second through holes 31 are correspondingly provided on the waterproof ring 3 .

[0092] The first through hole 111 and the second through hole 31 are aligned with each other, and components such as screws or threaded rods can be used to pass through the first through hole 111 and the second through hole 31 to fix and cooperate with the mounting structure of the lamp, so as to fix and install the lens assembly 1, the waterproof ring 3 and the mounting structure of the lamp; the second through hole 31 on the waterproof ring 3 can be used for the screw to pass through. Compared with the conventional non-penetrable structure, this design can prevent the screw from being lifted up by the colloid, thereby ensuring the relative position between the lens assembly 1 and the light source 41 is accurate, so that the actual optical parameters of the product when used are closer to the design values.

[0093] like Figure 11-13 As shown, the second through hole 31 is an opening on the waterproof ring 3, and the hole edge is the structure of the waterproof ring 3. During installation, the hole edge structure of the second through hole 31 can be fixed and pressed by components such as screws or bolts, so that the hole edge structure can fit tightly with the fixed edge 11 to improve the waterproof effect.

[0094] Further preferably, in order to improve the waterproof effect of the entire assembly structure, the first through holes 111 can be evenly distributed on the fixed edge 11, so as to achieve a press fit of each part. The aperture of the first through hole 111 can be similar to that of the second through hole 31; the first through hole 111 can be designed as a countersunk hole, and the sinking part of the countersunk hole is located on the light-emitting side of the lens assembly 1; in some cases, a thread can be provided inside the first through hole 111.

[0095] In one or more preferred embodiments, a clamping column 15 is provided on one side of the lens plate 14 close to the groove 12 , and a clamping ring 25 is correspondingly provided on the reflective cup assembly 2 . The clamping column 15 can be elastically engaged with the clamping ring 25 .

[0096] like Figure 8 As shown, the clamping column 15 can be a protruding columnar structure, and the clamping ring 25 has an opening for the clamping column 15 to extend into, and at least part of the side wall of the opening is elastic. When installing, the clamping column 15 can be extended into the opening and squeeze the elastic side wall, so that the clamping column 15 and the clamping ring 25 are elastically engaged. The elastic engagement can temporarily fix the reflector assembly 2 and the lens assembly 1, so that the lens assembly 1 and the reflector assembly 2 can be assembled as a whole in the next step, so as to simplify the assembly process; in addition, the engagement between the clamping column 15 and the clamping ring 25 can also reduce the shaking of the reflector assembly 2 relative to the lens assembly 1 when the lamp is assembled.

[0097] Preferably, the clamping ring 25 includes an elastic arc strip and an outer space for the arc strip to move, and one end of the arc strip can be fixedly connected to the reflective cup plate 24, and an opening for the insertion of the clamping column 15 is reserved between the arc strip and the reflective cup plate 24. The size of the opening can be slightly smaller than the width of the clamping column 15, so that the extension of the clamping column 15 can push the arc strip to achieve elastic fit.

[0098] Preferably, a transition portion with a smaller cross-sectional size may be provided at one end of the clamping column 15 away from the lens assembly 1 , and the cross-sectional size of the transition portion may gradually decrease in a direction away from the lens assembly 1 to facilitate alignment of the opening.

[0099] In one or several preferred embodiments, a first positioning structure is arranged between the lens assembly 1 and the reflective cup assembly 2, and the first positioning structure includes a first positioning column 16 and a first positioning column hole 26 which are arranged correspondingly; the first positioning column 16 and the first positioning column hole 26 can be arranged on the lens assembly 1 and the reflective cup assembly 2 respectively, and the accurate assembly of the lens assembly 1 and the reflective cup assembly 2 can be achieved through the positioning effect of the first positioning column 16 and the first positioning column hole 26.

[0100] A first arrangement of the first positioning structure is as follows: the first positioning column 16 is located on the lens plate 14 and extends toward the reflective cup plate 24 , and the first positioning column hole 26 is located on the reflective cup plate 24 .

[0101] The second arrangement of the first positioning structure is as follows: the first positioning column 16 is located on the reflective cup plate 24 and extends toward the lens plate 14 , and the first positioning column hole 26 is located on the lens plate 14 .

[0102] The first arrangement is preferred in this embodiment.

[0103] Preferably, the number of the first positioning posts 16 and the number of the first positioning post holes 26 are both at least two, and the two first positioning structures are arranged at intervals, which play a role in left and right positioning, and are beneficial to improving the optical effect of the lamp after assembly.

[0104] Further preferably, the first positioning structure is located at a position close to the center of the edge of the lens assembly 1, and the first positioning structure is symmetrically distributed or array distributed.

[0105] In one or more preferred embodiments, at least two lens optics 13 are disposed on the lens assembly 1 , and at least two reflector optics 23 are disposed on the reflector assembly 2 . The lens optics 13 are aligned and matched with the reflector optics 23 .

[0106] like Figure 6 , 9 As shown in FIG. 10 , a plurality of lens optics 13 can be connected and fixed by a lens plate 14, and a plurality of reflective cup optics 23 can be connected and fixed by a reflective cup plate 24. The lens optics 13 are aligned with the reflective cup optics 23, so that light can be adjusted together by the reflective cup optics 23 and the lens optics 13 before being emitted, thereby improving the optical effect of the lamp.

[0107] The present application does not limit the arrangement of the lens optics 13 and the reflective cup optics 23; it can be as follows Figure 6The 5×5 arrangement shown can also be arranged by an indefinite number N according to the use requirements; the overall shape of the lens assembly 1 can be square, rectangular, polygonal, fan-shaped, circular, etc. The reflective cup optics 23 preferably corresponds to the lens optics 13 one by one, but it is not excluded that some of them do not correspond; the cross-sectional shape of the reflective cup optics 23 can also be various, such as: circular, square, etc.
