[0018] References to "embodiments" in this document mean 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 phrase appears in various places in the specification and 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.

[0019] The present utility model discloses a specific implementation manner of a lens for a television. Please refer to Figures 1 to 3 , the lens includes a base 1. A reflecting cup 2 is formed on the top surface of the base 1. A circular ring 11 extends downward from the middle of the bottom surface of the base 1. A first blind hole 31 located inside the circular ring 11 is formed in the middle of the bottom surface of the base 1. A second blind hole 32 located inside the reflecting cup 2 is formed at the bottom of the first blind hole 31. A third blind hole 33 recessed inward is formed in the middle of the top surface of the reflecting cup 2.

[0020] In this embodiment, a rounded transition surface 14 is provided at the junction of the outer side surface of the circular ring 11 and the base 1. The rounded transition surface 14 can better absorb stray light of the light source, prevent light leakage, and the light inlet hole can also be appropriately made smaller to make the light spot larger.

[0021] In this embodiment, the longitudinal cross-sectional shape of the first blind hole 31 is trapezoidal, and the longitudinal cross-sectional shape of the second blind hole 32 is bullet-shaped. By setting the second blind hole 32 to be bullet-shaped, an arc structure is formed at the edge of the light inlet hole. A recessed third blind hole 33 is provided on the top surface of the reflecting cup 2, so that the light-emitting surface of the lens forms a flat wavy structure. The combination of the arc structure and the flat wave structure can increase the light spot angle while reducing the thickness of the product.

[0022] As an improvement, three convex strips 12 are extended downward from the bottom surface of the base 1 and arranged at intervals in the circumferential direction, so that a card slot 13 is formed between two adjacent convex strips 12. Optionally, each convex strip 12 is arranged in an arc shape, and the outer side surface of each convex strip 12 is a vertical plane, and the inner side surface of each convex strip 12 is an inclined plane. The convex strip 12 with this structure is more convenient for patch assembly, and the inclined plane can play a guiding role to make the patch assembly more convenient and fast.

[0023] As a preferred solution, the cross-section of each card slot 13 is trapezoidal. This structure of the card slot 13 is more conducive to assembly by rotation, improving the convenience of assembly and thus improving production efficiency.

[0024] Compared with the prior art, by setting three convex strips 12 to position the lens, a card slot 13 formed between two adjacent convex strips 12 can cooperate with an external card projection, so that it is applicable to electronic accessories that cannot be provided with card holes, solving the problem of inconvenient installation in the past.

[0025] Finally, it should be noted that what is disclosed in an embodiment of the present utility model for a lens for a television is only the preferred embodiment of the present utility model, which is only used to illustrate the technical solution of the present utility model, rather than limiting it; although the present utility model 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 recorded 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 utility model.
