Since the zoom lens 9 functions to move away from or close to the illumination light source 2 to perform the focusing function of the lamp, the zoom lens 9 should be restricted from rotating following the focus ring 10. Although the inner wall of the spiral groove 101 abuts against the protrusion 91 when the focusing ring 10 rotates, so as to move the zoom lens 9 up and down, a situation that the zoom lens 9 rotates along with the focusing ring 10 and cannot move up and down accurately may also occur, in order to avoid this situation, it is ensured that the electric zoom assembly can accurately focus the lamp, a vertical guide groove 1101 is arranged on the inner wall of the guide ring 110, the guide groove 1101 extends outwards from the inner wall of the guide ring 110, the long protrusion 911 penetrates through the corresponding spiral groove 101 and extends into the guide groove 1101, and the guide groove 1101 is used for limiting the transverse movement of the long protrusion 911, so that the long protrusion 911 can only slide up and down along the guide groove 1101.

The arrangement of the guide groove 1101 limits the transverse movement of the long bulge 911, so that the situation that the zoom lens 9 rotates along with the rotation of the focusing ring 10 is avoided, the zoom lens 9 can only move up and down relative to the focusing ring 10 is ensured, and the normal focusing function of the lamp is ensured. The guide ring 110 is sleeved on the focusing ring 10 and is installed on the lamp housing 1, specifically, an internal thread is arranged on the inner wall of the guide ring 110, an external thread corresponding to the internal thread is arranged on the outer wall of the lamp housing 1, and then the guide ring 110 is screwed on the lamp housing 1; since the focus ring 10 is rotatable with respect to the guide ring 110, when focusing, the zoom lens 9 is moved up and down within the focus ring 10 and the guide ring 110 by rotating the focus ring 10 clockwise or counterclockwise, so that the distance between the zoom lens 9 and the lamp source becomes larger or smaller, thereby realizing focusing.

The above only is the preferred embodiment of the present invention, not limiting the scope of the present invention, all the equivalent structure changes made by the contents of the specification and the drawings under the inventive concept of the present invention, or the direct/indirect application in other related technical fields are included in the patent protection scope of the present invention.

the bulge (91) at least comprises a long bulge (911), and the long bulge (911) penetrates through the corresponding spiral groove (101) and extends into the guide groove (1101), so that the zoom lens (9) can only slide up and down along the guide groove (1101).
