[0022] The technical scheme in the utility model embodiment will be described clearly and completely in conjunction with the drawings.

[0023] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the utility model embodiments are only used to explain the relative position relationship, movement condition, etc. between components in a certain specific posture (as shown in the drawings), and if the specific posture changes, the directional indications will also change accordingly. In addition, the descriptions involving "preferred", "second preferred" and the like in the utility model are only for descriptive purposes, and cannot be understood as indicating or implying the relative importance of the indicated technical features or implicitly indicating the number of indicated technical features. Therefore, the features with "preferred", "second preferred" can explicitly or implicitly include at least one of the features.

[0024] As Figures 1-4As shown, a rotating zoom lens assembly includes a support base 1, which is provided with a base cavity 11 opening upward. A lens 2 and a zoom plate 3 that locks the lens 2 in the base cavity 11 are sequentially provided in the base cavity 11. A positioning protrusion 21 extending outward and pressing against the open end of the support base 1 is provided on the upper side of the lens 2. A texture structure 4 is provided on the upper side of the lens 2 and the lower side of the zoom plate 3 to enable the zoom to change when the zoom plate 3 and the lens 2 rotate relative to each other. A plurality of upwardly extending buckles 12 are provided at the open end of the support base 1. A plurality of blocks 31 are provided on the side of the zoom plate 3 that respectively engage with the buckles 12. The width of the buckle 12 is greater than the width of the blocks 31, so that the zoom plate 3 can rotate relative to the lens 2. The texture structure 4 is a laser-engraved texture, specifically a laser-engraved gradient compound eye surface. During actual zooming, the zoom plate 3 is rotated, causing it to rotate relative to the lens 2. This rotational change between the textured structure 4 on the upper side of the lens 2 and the textured structure 4 on the lower side of the zoom plate 3 adjusts the focal length of the lens assembly, changing the LED beam angle and simplifying the zoom operation. Simultaneously, the width of the clip 12 and the width of the block 31 coordinate to limit the rotational angle range of the zoom plate 3 relative to the lens 2, thereby limiting the zoom range of the lens assembly. In this case, the rotational angle range of the zoom plate 3 relative to the lens 2 is 0-15 degrees.

[0025] like Figures 1-4 As shown, a sliding protrusion 32 is provided on the side of the zoom plate 3, which extends downward and can slide on the upper side of the positioning protrusion 21, reducing the contact area between the zoom plate 3 and the positioning protrusion 21, reducing the mutual friction, and thus better enabling the zoom plate 3 to rotate relative to the lens 2.

[0027] like Figures 1-4As shown, the upper surface of the lens 2 is provided with a lens upper concave groove 23 in the shape of a truncated cone, the bottom of the lens upper concave groove 23 is provided with a lens bottom exit surface 24, the side of the lens upper concave groove 23 forms a lens side exit surface 25, the bottom of the zooming piece 3 is provided with a zooming piece truncated cone part 33 extending downward and fitted into the lens upper concave groove 23, the bottom of the zooming piece truncated cone part 33 is provided with a zooming piece bottom incident surface 34, the side of the zooming piece truncated cone part 33 forms a zooming piece side incident surface 35, the texture structure 4 is arranged on the lens bottom exit surface 24, the lens side exit surface 25, the zooming piece bottom incident surface 34 and the zooming piece side incident surface 35 respectively; the upper surface of the zooming piece 3 is provided with a zooming piece concave groove 36 in the shape of a truncated cone, the bottom of the zooming piece concave groove 36 is provided with a zooming piece bottom exit surface 37, the side of the zooming piece concave groove 36 forms a zooming piece side exit surface 38; in the first embodiment, the lower side incident end of the lens 2 is provided with a lens light inlet hole 26, the groove bottom of the lens light inlet hole 26 is provided with a lens bottom arc-shaped incident surface 27 protruding downward, the side of the lens light inlet hole 26 forms a lens side incident surface 28, the lower side incident end of the base concave cavity 11 is provided with a base light inlet hole 14 below the lens light inlet hole 26; the groove bottom of the base light inlet hole 14 is provided with a base bottom arc-shaped incident surface 15 protruding upward, the upper side of the base light inlet hole 14 is provided with a base upper side arc-shaped exit surface 16, the base upper side arc-shaped exit surface 16 is provided with the texture structure 4. When assembled, the LED lamp is mounted on the base light inlet hole 14. When the LED lamp emits light, the LED lamp light enters the base light inlet hole 14 of the support base 1, passes through the base bottom arc-shaped incident surface 15 and the base upper side arc-shaped exit surface 16, enters the lens light inlet hole 26 of the lens 2, and then enters the lens upper concave groove 23 after passing through the lens bottom arc-shaped incident surface 27 and the lens side incident surface 28, enters the zooming piece truncated cone part 33 after passing through the lens bottom exit surface 24 and the lens side exit surface 25, enters the zooming piece concave groove 36 after passing through the zooming piece bottom incident surface 34 and the zooming piece side incident surface 35, and finally exits the lens assembly from the zooming piece bottom exit surface 37 and the zooming piece side exit surface 38.

The base upper side arc-shaped exit surface 16 is also provided with the texture structure 4, which better realizes focusing by rotating the LED light beam angle.
