Description

Technical Field

[0001] This utility model relates to the field of spotlight technology, specifically a spotlight with adjustable zoom. Background Technology

[0002] Spotlights, also known as LED spotlights, are electronic devices that create indoor lighting atmospheres. Their main characteristics are soft, elegant light. They can play a leading role in overall lighting or provide localized lighting to enhance the ambiance. Spotlights can freely change angles, and the combined lighting effects are endlessly varied. A row of small spotlights can create wonderfully varied patterns. Spotlights are a typical example of modern lighting without a main light or fixed scale, capable of creating indoor lighting atmospheres. Because the small spotlights can freely change angles, the combined lighting effects are endlessly varied. Spotlight light is soft and elegant, and it can also provide localized lighting to enhance the ambiance.

[0003] However, existing spotlights use a fixed focal length optical system in their design. This means that once a spotlight is manufactured, its focal length is fixed and cannot be changed by adjustment. This design simplifies the structure and manufacturing process of the spotlight, but limits its zoom capability, which may restrict the light distribution and lead to uneven light distribution in the illuminated area. This may result in some areas being too bright or too dark, affecting the lighting effect. Therefore, we need a spotlight that can adjust the zoom back and forth. Utility Model Content

The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a mutually exclusive, independent, or alternative embodiment. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0024] This utility model embodiment provides a spotlight with adjustable zoom, such as... Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, the lamp includes a lamp body 1, with a heat sink 2 threadedly connected to the top of the lamp body 1. An adjustment assembly 3 is installed inside the lamp body 1, and a mounting assembly 4 is threadedly connected to the outer wall of the lamp body 1. A light source 5 is fixedly connected inside the lamp body 1. The adjustment assembly 3 includes a tension rod 301, with a threaded bottom 302. The lamp body 1 forms a rotating structure via the tension rod 301, and the top of the tension rod 301 passes through the heat sink 2 for connection, allowing the tension rod 301 to be securely fastened within a tension ring 303. The tension rod 301, penetrating between the heat sink 2 and the lamp body 1, improves the adjustment mechanism. For easy adjustment of the spotlight, a tension ring 303 is threadedly connected to the bottom of the tension rod 301. A threaded groove 304 is formed on the top of the tension ring 303. The tension ring 303 and the bottom of the tension rod 301 form a threaded structure through the threaded groove 304. The shape and size of the threaded groove 304 match the shape and size of the bottom of the tension rod 301, and one end of the bottom of the tension rod 301 extends into the threaded groove 304 for connection. This strengthens the connection between the tension ring 303 and the bottom of the tension rod 301, allowing the bottom of the tension rod 301 to be securely fastened within the threaded groove 304 of the tension ring 303. A lens 305 is fixedly connected inside the tension ring 303. An internal thread 306 is formed inside the tension ring 303, and a pressure ring 307 is connected to this internal thread. The tension ring 303 and the pressure ring 307 form a threaded structure through the internal thread 306, and the shape and size of the pressure ring 307 match the shape and size of the internal thread 306. Furthermore, the outer wall of the pressure ring 307 fits snugly against the inner wall of the internal thread 306, enhancing the connection between the tension ring 303 and the pressure ring 307. This allows the pressure ring 307 to be securely fastened within the tension ring 303, limiting the connection between the lens 305 and the light-transmitting film. In position, a silicone ring 308 is fitted onto the outer wall of the tension ring 303. By rotating the tension rod 301, the tension rod 301 is fixed in the screw groove 304 inside the tension ring 303. At this time, by pulling the tension rod 301 down or up, the lens 305 inside the tension ring 303 can be moved. Relying on the silicone ring 308, good damping is ensured during the tensioning movement. The movement of the tension ring 303 will move the lens 305 together, while the light source 5 remains stationary. This changes the relative distance between the lens 305 and the light source 5, thereby achieving zoom.

[0025] In a further preferred embodiment of this utility model, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6As shown, the mounting component 4 includes an external thread 401. A first threaded ring 402 is threadedly connected to the outer wall of the lamp body 1. The lamp body 1 forms a threaded structure with the first threaded ring 402 through the external thread 401. The shape and size of the external thread 401 match the shape and size of the first threaded ring 402, and the inner wall of the first threaded ring 402 fits snugly against the outer wall of the external thread 401, enhancing the connection between the lamp body 1 and the external thread 401. This allows the first threaded ring 402 to be fastened to the outer wall of the lamp body 1 by its internal thread. A fixing ring 403 is fixedly connected to the outer wall of the first threaded ring 402. A second threaded ring 405 is threadedly connected to the outer wall of the first threaded ring 402. The outer ring 404 forms a threaded structure with the first threaded ring 402 through the second threaded ring 405. The inner wall of the second threaded ring 405 is fitted against the outer wall of the first threaded ring 402, which strengthens the connection between the first threaded ring 402 and the second threaded ring 405. The second threaded ring 405 can be installed by relying on its internal threads to be fastened to the outer thread of the first threaded ring 402. The bottom of the second threaded ring 405 is fixedly connected to an outer ring 404. The outer thread of the second threaded ring 405 is threadedly connected to a movable ring 406. The movable ring 406 and the second threaded ring 405 form a threaded structure, and the inner wall of the movable ring 406 is fitted against the outer wall of the second threaded ring 405, which strengthens the connection between the movable ring 406 and the second threaded ring 405. The movable ring 406 can rotate and move on the outer wall of the second threaded ring 405 by relying on its internal threads.

[0026] Working principle: In use, the first threaded ring 402 can be screwed into the outer wall of the lamp body 1, and the first threaded ring 402 can be fastened to the outer wall of the external thread 401 for installation. After installation, the movable ring 406 is screwed into the outer wall of the second threaded ring 405, and the second threaded ring 405 can be directly sleeved on the outside of the first threaded ring 402. When the second threaded ring 405 is rotated, the second threaded ring 405 can be fastened to the outer wall of the first threaded ring 402 by the internal thread for installation. At this time, the movable ring 406 can rotate and move freely on the outer wall of the second threaded ring 405. The movement can be adjusted by adjusting the movable ring 406 and the outer ring 401. The spacing between the four elements is designed to facilitate positioning after clamping the plate. Furthermore, when adjusting the zoom of the spotlight, the tension rod 301 is rotated to secure it within the screw groove 304 of the tension ring 303. Pulling the tension rod 301 downwards or upwards moves the lens 305 within the tension ring 303. The silicone ring 308 ensures good damping during the stretching motion. The movement of the tension ring 303 carries the lens 305 along with it, while the light source 5 remains stationary. This alters the relative distance between the lens 305 and the light source 5, thus achieving zoom.
