[0031] To make the technical solution and features of this utility model clearer, the following detailed description of this utility model is provided in conjunction with the accompanying drawings and specific examples. It should be understood that these examples are only for illustrating this utility model and are not intended to limit the scope of this utility model. After reading this utility model, any modifications of this utility model by those skilled in the art in various equivalent forms fall within the scope defined by the appended claims.

[0032] refer to Figures 1-10 This embodiment provides an adjustable focal length lamp, including: a lamp body 9, a light-emitting component 8 disposed in the lamp body 9, and a lens 4 disposed in front of the light-emitting component 8 along the light path direction;

[0033] It also includes an adjustment component, which is engaged with the lens 4 in a reversing transmission to change the rotation of the adjustment component into the movement of the lens 4 along the axial direction of the lamp body 9, so as to adjust the distance between the lens 4 and the light-emitting component 8.

[0034] Specifically, the adjustment assembly includes a knob 17 and a rotating rod 11. The knob 17 is exposed outside the lamp body 9 and is fixedly connected to one end of the rotating rod 11. The other end of the rotating rod 11 extends horizontally along the axial direction of the lamp body 9 and is provided with gear teeth 11-1 and gear 7, which are internal gear teeth 7-1 distributed circumferentially along the lamp body 9. The gear 7 is fixedly connected to the rotating wheel 6, and the lens 4 is fixed on the rotating wheel 6. The gear 7, rotating wheel 6, and lens 4 are fixed as one fixed component. Thus, rotating the knob 17 can drive the gear 7, rotating wheel 6, and lens 4 to rotate together.

[0035] It also includes a retaining ring 5, the edge of which extends radially outward with a raised edge. The raised edge has a hole 5-1 spaced apart for fixed connection with the lamp body 9, thus keeping the retaining ring 5 stationary. The inner wall of the retaining ring 5 has at least one first thread; in this embodiment, there are four. The outer wall of the rotating wheel 6 has a second thread corresponding to the first thread; the first and second threads cooperate to reverse the rotation of the rotating wheel 6 into axial movement of the rotating wheel 6 along the lamp body 9.

[0036] Through the above transmission design, rotating the knob 17 can move the lens 4 up and down, creating a variable distance between it and the lamp bead 8, thereby achieving the purpose of adjusting the light emission angle.

[0037] Furthermore, a rear cover 16 is provided on the side of the lamp body 9 away from the light-emitting surface. A pressure ring 19 is connected to the rear cover 16 at the position corresponding to the knob 17 so as to place the knob 17 inside the pressure ring 19. It also includes a tail cover 21 for covering the knob 17. The tail cover 21 is connected to the pressure ring 19 by a thread.

[0038] This embodiment also includes a lampshade assembly, which is divided into an outer cover 1 and a lampshade 2. A first sealing ring 3 is pressed between the lampshade 2 and the lamp body 9; a second sealing ring 12 is pressed between the lamp body 9 and the rear cover 16; a third sealing ring 18 is provided between the rear cover 16 and the pressure ring 19; and a fourth sealing ring 20 is provided between the pressure ring 19 and the tail cover 21.

[0039] In order to connect the back cover 16 and the lamp body 9, the back cover 16 is fixed to the lamp body 9 by screws, and a waterproof sealing plug is provided in the screw hole of the back cover 16.

[0040] Furthermore, the rear cover 16 is rotatably connected to a connector to adjust the tilt angle of the lamp body 9. Specifically, the rear cover 16 is rotatably connected to the connector 25 by bolts. A fifth sealing ring 24 is provided between the bolts and the inner wall of the connector 25, and a sixth sealing ring 23 is provided between the rear cover 16 and the connector 25, thus completing the waterproof sealing of the entire lamp.

[0041] Finally, it also includes a DIP switch 15 for adjusting color temperature or brightness, the DIP switch 15 being placed inside the pressure ring 19.

[0042] The above is only one specific embodiment of the present utility model, but the design concept of the present utility model is not limited thereto. Any non-substantial modifications made to the present utility model using this concept shall be deemed as an infringement of the protection scope of the present utility model.
