Description

Technical Field

[0001] The invention relates to the technical field of flashlight lens assemblies, in particular to a flashlight lens assembly capable of preventing light leakage. Background Art

[0002] The main function of the flash lens assembly is to control the direction and intensity of light, thereby improving the shooting effect and user experience. By setting a light-blocking layer on the surrounding side of the flash lens to block the flash light, the light can be prevented from emitting from the surrounding side, ensuring that the light is emitted only from the light-emitting surface, thereby avoiding the problem of light leakage. The flash lens assembly converts the rigid direct flash light into soft diffuse light, eliminating the high spots on portraits and other photographed objects, making the photos look more natural. The flash lens assembly diffuses the light evenly, further softens the light, and expands the light range. The flash lens assembly limits the light through its grid pattern to make the light directional, creating a light source effect with a prominent center and soft light and dark transition at the edges. The flash lens assembly forms a soft light effect by reflecting light, which is suitable for portrait photography.

In the above-mentioned light leakage prevention flash lens, the assembly platform and the light guide column are integrally formed, the structure has strong stability, and the assembly efficiency is improved. The assembly platform is a black T-shaped structure, and the light guide column of the transparent cylindrical structure is received in the receiving channel. There will be no light leakage problem in the process of light entering the light guide column and leaving the light guide column, so that the photo effect is good.
