Description

Technical Field

[0001] This utility model relates to the field of lens structure technology, specifically to an LED lamp lens structure. Background Technology

[0002] LED lenses are optical systems closely linked to LEDs that enhance light utilization and luminous efficiency. They can be used to achieve different effects and come in various specifications, including transmissive and catadioptric types. Different lenses can be used to alter the light field distribution of the LED to achieve different effects.

[0003] Chinese patent CN217503550U discloses a lens structure for an LED light source, relating to the field of lens structure technology. The mounting base has a mounting groove on its side, and two cavities are formed inside the mounting base along the side of the mounting groove. Each cavity contains a limiting plate, and a spring is installed on one side of each limiting plate. A clip extending into the mounting groove is installed on the other side of each limiting plate. A pull rod extending outwards from the center of the side of each limiting plate is installed. The lamp is placed into the mounting groove, and the two clips are engaged with the lamp's slots to fix the lamp to the device. This allows the lamp to be freely detached from the device. If the lamp is damaged, it can be replaced without scrapping the entire device, reducing resource waste. The graphene sheet transfers the heat generated by the lamp during operation to the mounting base, and a ventilation fan sends external airflow through the ventilation groove into the ventilation slot, where it exchanges heat with the high-temperature mounting base, enhancing the lamp's heat dissipation.

[0004] However, in the above technical solution, the clip and the slot on the lamp are fixed and disassembled by simply pulling the lever to compress the spring. However, during installation, the angle between the clip and the slot needs to be matched in order to install quickly. Utility Model Content

[0020] Example 1

[0021] like Figures 1-4 As shown, the present invention proposes an LED lamp lens structure, including a lamp body 1, a fixing cylinder 2, a fixing component, a rotating cylinder 7, a lens body 8, and a focusing component, with the fixing cylinder 2 sleeved on the outside of the lamp body 1;

[0022] In an optional embodiment, the fixed cylinder 2 is composed of a first cylinder 9 and a second cylinder 10. The first cylinder 9 is rotatably connected to the rotating cylinder 7, and the second cylinder 10 is detachably connected to the first cylinder 9. The second cylinder 10 has a notch, and the second cylinder 10 has an installation groove 11 for accommodating the adjustment plate at one end near the first cylinder 9. The first cylinder 9 has a guide groove 12 that is slidably connected to the moving block 5.

[0023] The fixing component is connected to the fixing cylinder 2. The fixing component includes a rotating disk 3, a sliding rod 4, and a moving block 5. The rotating disk 3 has multiple adjustment slots 6. The number of sliding rods 4 and moving blocks 5 corresponds to the number of adjustment slots 6. One end of the sliding rod 4 is slidably connected to the adjustment slot 6, and the other end of the sliding rod 4 is connected to the moving block 5. A clamping plate is connected to the moving block 5. When the fixing component is in use, the rotating disk 3 rotates, which drives the sliding rods 4 and moving blocks 5 to move horizontally. The moving block 5 and the clamping plate move in a mirror motion to clamp the lamp body 1.

[0024] The rotating cylinder 7 is rotatably connected to the fixed cylinder 2 by a bearing. The rotating cylinder 7 and the fixed cylinder 2 have the same center. The lens body 8 is installed on the rotating cylinder 7.

[0025] In an optional embodiment, the rotating cylinder 7 is composed of a cylinder body 18 and a cylinder cover 19, which are connected by threads. The protective lens 17 is installed in the gap between the cylinder body 18 and the cylinder cover 19.

[0026] In an optional embodiment, a protective lens 17 is connected to the end of the rotating cylinder 7 away from the fixed cylinder 2; the protective lens 17 is used to block external dust and impurities and reduce the wear of external factors on the lens body 8.

[0027] The focusing assembly is connected to the rotating cylinder 7. When the focusing assembly is in use, the moving end of the adjusting assembly moves vertically along the rotating cylinder 7, causing the lens to move and adjust its distance from the lamp body 1.

[0028] Example 2

[0029] like Figures 2-4 As shown, the present invention proposes an LED lamp lens structure. Compared with Embodiment 1, this embodiment describes the detailed structure of the fixing component. The fixing component also includes an adjusting ring 13 and a connecting rod 14. The adjusting ring 13 is sleeved on the outside of the fixing cylinder 2, and the connecting rod 14 is connected to the adjusting ring 13. One end of the connecting rod 14 is connected to the rotating disk 3.

[0030] In an optional embodiment, the adjusting rings 13 are provided with anti-slip textures; the anti-slip textures are used to prevent the problem of difficulty in rotation caused by hand oil and wear of the adjusting rings 13 themselves;

[0031] Example 3

[0032] like Figures 2-3 As shown, the present invention proposes an LED lamp lens structure. Compared with Embodiment 2, this embodiment describes the detailed structure of the focusing assembly. The focusing assembly includes a guide rod 15 and a moving ring 16. Multiple guide rods 15 are distributed around the central axis of the fixed cylinder 2. One end of the guide rod 15 is connected to the fixed cylinder 2. The moving ring 16 is disposed inside the moving cylinder. The lens body 8 is detachably connected to the moving ring 16. The moving ring 16 is slidably connected to the guide rod 15. The moving ring 16 is threadedly connected to the rotating cylinder 7.

[0033] In summary, when using this invention, if the operator needs to adjust the gap between the lens body 8 and the lamp body 1 to obtain different focal lengths and lighting effects, the operator holds the fixed cylinder 2 with one hand and rotates the rotating cylinder 7 with the other. The rotation of the rotating cylinder 7 causes the threads on its inner wall to change, allowing the movable ring 16, which is threadedly connected to the rotating cylinder 7, to slide along the guide rod 15 in the direction perpendicular to the threads. The rising of the movable ring 16 causes the lens body 8 to move upwards, adjusting the distance between it and the lamp body 1 to obtain different focal lengths. When it is necessary to replace the lamp body 1, the operator rotates the fixed cylinder 2... The rotation of the joint ring 13 and the adjusting ring 13 will cause the connecting rod 14 to rotate around the central axis of the fixed cylinder 2 within the notch opened on the second cylinder 10. The connecting rod 14 is connected to the rotating disk 3, thereby causing the rotating disk 3 to rotate. As a result, the position of the adjusting groove 6 on the rotating disk 3 changes. The moving block 5 can only move horizontally towards the central axis of the fixed cylinder 2 within the guide groove 12. As the position of the arc-shaped adjusting groove 6 changes, it will cause the sliding rod 4 to move, thereby causing the moving block 5 to move horizontally closer to the center of the fixed cylinder 2. The clamping plate on the moving block 5 clamps and fixes the outer peripheral wall of the lamp body 1.

[0034] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
