Abstract
Description
Technical Field
[0001] This utility model relates to the field of optical lens technology, and in particular to an optical lens with omnidirectional polarization and variable focus adjustment. Background Technology
[0002] In the field of modern optics, optical lenses are widely used in photography, videography, medical equipment, scientific instruments, and lighting monitoring, among other applications. These applications demand diverse polarization and zoom capabilities from lenses.
[0003] Existing indoor lighting fixtures on the market, such as downlights, spotlights, and wall washers, have fixed illumination directions and areas once the fixtures are installed and fixed. If consumers need to change the illumination direction or require focused lighting in a certain area, they must readjust the installation position of the fixtures or replace the lenses with lenses of different angles. This brings great inconvenience to the use of the fixtures. Therefore, this application proposes an optical lens with omnidirectional polarization and adjustable focus. Utility Model Content
[0004] The purpose of this invention is to address the problem of non-adjustable lens angles in the prior art by proposing an optical lens with omnidirectional polarization and variable focus adjustment.
[0005] The technical solution of this utility model: an optical lens with omnidirectional polarization and variable focus adjustment, including a housing, and further comprising:
[0006] A connecting shell is threadedly installed inside an outer shell. One end of the connecting shell has a circular groove in which a lens is rotatably installed. One end of the lens is fixedly installed with a circular connecting plate, which is circular in shape. An adjustment mechanism capable of driving the lens to move horizontally is provided inside the outer shell.
[0007] Optionally, the adjustment mechanism includes an internal thread fixedly installed at one end of the housing, and an external thread fixedly installed on the outer side of the connecting housing, wherein the internal thread and the external thread are threadedly connected.
[0008] Optionally, a slot is provided on the connecting shell, and a card block is fixedly installed at one end of the shell, with the slot and the card block being slidably connected.
[0009] Optionally, a lamp wick is fixedly installed inside the housing, the lamp wick is connected to a power source, a light source bracket is fixedly installed on one side of the lamp wick, and a light source is disposed inside the light source bracket.
[0010] Optionally, a diffuser is fixedly installed inside the connecting shell, and the diffuser is fixedly connected to the circular groove.
[0011] Optionally, the depth of the card slot is -cm, and the upper surface of the card slot is provided with anti-slip texture.
[0012] Optionally, one side of the circular connecting plate is semi-circular, the circular groove is semi-circular, and the outer side of the circular connecting plate fits into the inner side of the circular groove.
[0013] Compared with the prior art, the present invention has the following beneficial technical effects:
[0014] This invention uses a circular connecting plate and a circular groove to engage, allowing the lens to rotate 30° within the diffuser, thus achieving polarization in any direction and improving the ease of operation of the lighting fixture.
[0015] Furthermore, by rotating the connecting shell, the connecting shell moves to one side of the outer shell, causing the lens to move forward and reduce the zoom angle. Rotating the connecting shell in the opposite direction increases the zoom angle, allowing for a beam angle of 15°-36°.
[0016] This invention improves the convenience and versatility of lighting fixtures, and optimizes the manufacturing and management costs of lighting fixtures. Attached Figure Description

[0029] Example
[0030] like Figure 1-2As shown, the present invention proposes an optical lens with omnidirectional polarization and variable focus adjustment, including a housing 1 and a connecting housing 2. The connecting housing 2 is threadedly installed inside the housing 1. One end of the connecting housing 2 has a circular groove 8. A lens 6 is rotatably installed in the circular groove 8. A circular connecting plate 7 is fixedly installed at one end of the lens 6. The circular connecting plate 7 is circular, and one side of the circular connecting plate 7 is semi-circular. The circular groove 8 is semi-circular. The outer side of the circular connecting plate 7 fits against the inner side of the circular groove 8, so that the lens 6 can rotate omnidirectionally within the circular groove 8 without falling off. It can achieve polarization of 30° in any direction. The housing 1 is provided with an adjustment mechanism that can drive the lens 6 to move horizontally.
[0031] like Figure 2-3 As shown, the adjustment mechanism includes an internal thread 3 fixedly installed at one end of the outer shell 1, and an external thread 4 fixedly installed on the outer side of the connecting shell 2. The internal thread 3 and the external thread 4 are threadedly connected. When the connecting shell 2 is rotated, the connecting shell 2 moves to one side of the outer shell 1, so that the lens 6 moves forward and the zoom angle is reduced. When the connecting shell 2 is rotated in the opposite direction, the zoom angle can be increased. The zoom beam angle can be 15°-36°.
[0032] like Figure 4-5 As shown, a slot 9 is provided on the connecting shell 2, and a block 10 is fixedly installed at one end of the outer shell 1. The slot 9 and the block 10 are slidably connected. A lamp wick 5 is fixedly installed inside the outer shell 1. The lamp wick 5 is connected to the power supply. A light source bracket 13 is fixedly installed on one side of the lamp wick 5. A light source 12 is provided inside the light source bracket 13. A diffuser 11 is fixedly installed inside the connecting shell 2. The diffuser 11 is fixedly connected to the circular groove 8. The depth of the slot 9 is 3-4cm. The upper surface of the slot 9 is provided with anti-slip texture to facilitate the rotation of the connecting shell 2.
[0033] Working principle: The connecting shell 2 is installed on the inner thread of the outer shell 1. The lens 6 is rotatably installed in the circular groove 8 at one end of the connecting shell 2. The lens 6 cooperates with the circular groove 8 through the circular connecting plate 7, which can rotate in all directions to achieve 30° polarization in any direction. The connecting shell 2 is threadedly connected to the inner thread 3 of the outer shell 1 through the external thread 4. Rotating the connecting shell 2 moves it in the outer shell 1, which drives the lens 6 to move horizontally, thereby changing the zoom angle. It can achieve a zoom of 15°-36° beam angle. The slot 9 on the connecting shell 2 is slidably connected to the slot 10 on the outer shell 1. The slot 9 is 3-4cm deep and has anti-slip texture for easy operation. This realizes the convenience and diversification of lighting fixtures, and optimizes the manufacturing and management costs of lighting fixtures.
[0034] The above specific embodiments are merely several optional embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
