[0017] As used herein, the term "embodiment" means that the specific features, structures, or characteristics described in connection with the embodiments can be included in at least one embodiment of the present utility model. The appearance of this phrase at various positions in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment mutually exclusive with other embodiments. Those skilled in the art will explicitly and implicitly understand that the embodiments described herein can be combined with other embodiments.

[0018] The present utility model discloses a specific implementation manner of a lens with a multi-layer reflecting cup. Please refer to Figures 1 to 2 , the lens includes a base 1. In the middle of the top surface of the base 1, a first frustum 21 extends upward. A first blind hole is formed downward on the top surface of the first frustum 21. From the bottom of the first blind hole, a second frustum 22 extends upward. A second blind hole is formed downward on the top surface of the second frustum 22. From the bottom of the second blind hole, a spherical surface portion 23 extends upward. A first reflecting cup is formed on the outer peripheral side surface of the first frustum 21, which is used for concentrating light. A second reflecting cup is formed on the outer peripheral side surface of the second frustum 22, which is used for spot neutralization and adjustment. A third reflecting cup is formed on the outer surface of the spherical surface portion 23, which is used for angle compensation. Through the design of the three-layer reflecting cup, it is possible to achieve light concentration, neutralization, and complementary angle adjustment, so that after the lens emits light, the effect of uniform spot, accurate angle, and high light intensity efficiency can be achieved.

[0019] As an improvement, a clamping claw 3 is provided on each of the left and right sides of the base 1. At the top end of each clamping claw 3, a clamping hook 31 extending outward is formed. In other embodiment manners, clamping claws 3 are provided on the upper and lower sides of the base 1 respectively, which can further improve the installation firmness and ensure the convenience and reliability of the lens installation.

[0020] To further improve the installation structure strength, a plurality of positioning columns 13 arranged at intervals in the circumferential direction are further provided on the top surface of the base 1. Each positioning column 13 is located outside the first frustum 21. The positioning columns 13 can cooperate with external positioning holes to form a plug-in structure, which can further limit the lens, reduce the occurrence of the clamping claw 3 breaking. And even if the clamping claw 3 breaks, the positioning function of the positioning columns 13 can prevent the lens from shifting, and cooperate with the clamping claw 3 to play a dual limiting role. By providing paired clamping claws 3, it is more convenient for the subsequent installation of the product, ensuring the concentricity of the light source and the light-emitting hole of the lens, and solving the problem of inconvenient installation in the past.

[0021] As another improvement, a groove 11 arranged in the circumferential direction is formed on the outer peripheral side surface of the base 1. The groove 11 is mainly used for installing an external sealing gasket. By providing the groove 11, an installation position for installing the sealing gasket is formed. After installing the sealing gasket, it can ensure that the product has a waterproof function when used outdoors.

[0022] In this embodiment, a surrounding portion 12 extends outward from the bottom of the base 1. The outer contour of the surrounding portion 12 is a polygon, and the polygon structure can play an anti-fooling role, making it more convenient for the subsequent installation of the lens. Moreover, the setting of the surrounding portion 12 enables a stepped structure to be formed at the groove 11 of the base 1, providing a certain basis for subsequent waterproof sealing.

[0023] Finally, it should be noted that what is disclosed in the lens with a multi-layer reflecting cup according to the embodiment of the present invention is only the preferred embodiment of the present invention, which is only used to illustrate the technical solution of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
