Description

Technical Field

[0001] The utility model relates to the technical field of photographic and video equipment, in particular to a light guide structure for a lens and a lens. Background Art

[0002] At present, in photographing and video recording equipment, when the brightness is insufficient, the light source of the equipment itself will emit light to assist photographing and video recording. Generally, the light emitted by this type of light source generally has a corresponding light guide structure to assist the light guide of the light source.

[0003] In the prior art, the light-guiding structure is usually designed with ribs in the lens barrel. When the lens plate and the lens barrel are installed, the ribs are connected to the LED lights on the lens plate to assist in light guiding. Since there is a certain installation space between the lens plate and the lens barrel, the volume of the ribs used for light guiding is also large, which affects the installation of other structures in the lens barrel. Moreover, the ribs and the LED lights on the lens plate are both made of hard materials, and there are gaps when they contact each other, resulting in a certain amount of light leakage. At the same time, the LED lights are easily damaged if the position is incorrect during installation.

[0004] Therefore, there is an urgent need for a light guide structure for a lens and a lens to solve the above technical problems. Utility Model Content

[0036] Please refer to Figure 1 and Figure 2 The present embodiment provides a lens, which includes a lens barrel 100, a lens board 200 and a light-guiding structure for the lens in the present embodiment. The lens barrel 100 and the lens board 200 are fixedly connected. The light-guiding structure for the lens is arranged between the lens barrel 100 and the light source part 210 of the lens board 200 to achieve a light-guiding effect on the light source part 210 and prevent light leakage, thereby improving the reliability of the optical path of the lens.

[0037] Furthermore, a plurality of fixing parts 110 are provided on the inner bottom wall of the lens barrel 100 , and the lens plate 200 is fixed on the fixing parts 110 , so that a fixed connection between the lens barrel 100 and the lens plate 200 is achieved.

[0038] In order to realize the light guiding function of the lens and prevent light leakage, the present embodiment further provides a light guiding structure for the lens, so that the light emitted by the light source will be guided out of the lens. At the same time, no light leakage will occur in the light guiding process, causing the problem that the emitted light cannot meet the use requirements, thereby improving the reliability of the lens.

[0039] Please refer to Figures 1 to 3 Specifically, the light guide structure for the lens includes a light guide seat 10, a light guide member 20 and a light shielding assembly 30. The light guide seat 10 is arranged on the inner wall of the lens barrel 100; the light guide member 20 is arranged in the light guide seat 10, and the light guide member 20 is used to guide the light emitted by the light source member 210 of the lens board 200; the light shielding assembly 30 is sleeved on the outer periphery of the connection between the light guide seat 10 and the light source member 210 to shield the light emitted by the light source member 210.

[0040] The light-guiding structure for the lens of the present embodiment can prevent the light emitted by the light source part 210 from escaping outward by providing a shading component 30 on the periphery of the light guide seat 10 and the light source part 210. That is, the light emitted by the light source part 210 is emitted from the light guide seat 10 along the inside of the shading component 30 and the light guide part 20, thereby avoiding the occurrence of light leakage at the connection between the light guide seat 10 and the light source part 210. Moreover, by providing the shading component 30, there is no need to design the light guide seat 10 and the light guide part 20 that cooperate with the light source part 210 too long, thereby reducing the volume of the light guide seat 10 and the light guide part 20, thereby improving the space utilization rate of the light-guiding structure for the lens.

[0041] Please refer to Figure 1 and Figure 3 In the present embodiment, the shading assembly 30 includes a first shading member 31, which is clamped between the light guide seat 10 and the lens board 200, and the first shading member 31 is sleeved on the outer periphery of the light source member 210, which can not only cover the outer periphery of the light source member 210 to prevent the light emitted by the light source member 210 from being scattered, but also the first shading member 31 is clamped by the light guide seat 10 and the lens board 200, so that the first shading member 31 can fill the sides of itself that are in contact with the light guide seat 10 and the lens board 200 respectively, and the light of the light source member 210 will not be scattered from the gap at the above-mentioned connection, thereby improving the utilization rate of light.

[0042] Specifically, the first light shielding member 31 defines a first through hole 311 , the light source member 210 can pass through the first through hole 311 , and the light emitted by the light source member 210 can travel along the first through hole 311 to the light guide member 20 and be emitted from the light guide member 20 .

[0043] Furthermore, the shading assembly 30 also includes a second shading member 32, and the second shading member 32 is mounted on the periphery of the light guide seat 10 and the first shading member 31, that is, the second shading member 32 is arranged on the periphery of the first shading member 31 and the light guide seat 10, so as to provide secondary protection for the light emitted by the light source member 210, thereby better preventing the light from being scattered during the light propagation process of the light source member 210.

[0044] Specifically, the second light shading member 32 has a second through hole 321, and the first light shading member 31 and the light guide seat 10 can be passed through the second through hole 321, further ensuring that even if the light is scattered to the first light shading member 31, it will be blocked by the second light shading member 32, and the second light shading member 32 gives radial force to the first light shading member 31, squeezing the first light shading member 31 to completely wrap the light source member 210, thereby reducing the generation of gaps.

[0045] Optionally, the first shading member 31 and the second shading member 32 are both made of shading foam or shading silicone, both can achieve their shading function, and the structure has a certain flexibility and will not cause damage to the light source member 210 and the light guide seat 10, thereby improving the service life of the light guide structure for the lens.

[0046] Optionally, the first light shielding member 31 and the second light shielding member 32 are both provided with adhesive backing to be used for fixing the first light shielding member 31 and the second light shielding member 32 to other structures.

[0047] Please refer to Figure 1 and Figure 3 In this embodiment, the light guide seat 10 is disposed on the inner bottom wall of the lens barrel 100 , and the light guide seat 10 and the fixing portion 110 are both disposed on the same wall of the lens barrel 100 , and the light guide seat 10 is lower than the fixing portion 110 , thereby reducing the volume of the light guide seat 10 .

[0048] Furthermore, a limiting step portion 11 is provided on the outer periphery of the light guide seat 10, and a second light shading member 32 is arranged on the limiting step portion 11 to support the second light shading member 32, so that the second light shading member 32 is supported to prevent it from slipping and causing light leakage during use; and the second light shading member 32 can be clamped by the limiting step portion 11 and the lens plate 200 to generate a compression amount, thereby ensuring the light shading effect of the second light shading member 32.

[0049] Furthermore, the light guide seat 10 is provided with a light guide hole 12, and the light guide component 20 is arranged in the light guide hole 12. The light guide hole 12 and the first through hole 311 form a light guide path. The light guide component 20 is arranged in the light guide hole 12, which can not only install the light guide component 20, but also guide the light emitted by the light source component 210.

[0050] Optionally, the hole wall of the light guide hole 12 is provided with a first step portion 121 , and the light guide member 20 is provided with a second step portion 21 . The first step portion 121 and the second step portion 21 are arranged in coordination to achieve the limiting effect of the light guide hole 12 on the light guide member 20 .
