Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of flash lens assemblies, in particular to a flash lens assembly capable of preventing light leakage. BACKGROUND

[0002] The main function of the flash lens assembly is to control the direction and intensity of light emission, thereby improving the shooting effect and user experience. By arranging a light-blocking layer on the peripheral side of the flash lens to block the light of the flash, the light can be prevented from emitting from the peripheral side, ensuring that the light only emits from the light-emitting surface, thereby avoiding the problem of light leakage. The flash lens assembly converts the direct light of the rigid flash into soft diffused light, eliminating the highlight spots on the portrait and other shooting objects, making the photos look more natural. The flash lens assembly uniformly diffuses the light, further softens the light, and expands the light range. The flash lens assembly limits the light through its grid pattern, giving the light directionality, creating a light source effect with a central highlight and a soft transition from the edge to the dark, and the flash lens assembly forms a soft light effect by reflecting the light, which is suitable for portrait photography.

[0003] The contrast file, application number CN201621194575.2, relates to a light leakage prevention flash lens, which comprises an assembly platform and a light guide column integrally formed with the assembly platform. The assembly platform is a black T-shaped structure with a receiving channel passing through the assembly platform in the middle. The light guide column is a transparent cylindrical structure and is received in the receiving channel. The side wall of the light guide column is connected with the inner wall of the receiving channel. One end of the light guide column is provided with a light inlet surface, and the other end is provided with a light outlet surface. The light inlet surface is located at one end of the receiving channel, and the light outlet surface is located at the other end of the receiving channel and is flush with the other end of the receiving channel. The light leakage prevention flash lens has the advantages of stable structure and high assembly efficiency. The transparent cylindrical structure of the light guide column is received in the receiving channel, so that there is no light leakage problem during the process of light entering and leaving the light guide column, and the shooting effect is good.

[0004] The contrast file, application number CN201520363653.6, discloses a flash lens that can avoid light leakage, which comprises a main body. The bottom surface of the main body is concave and has a receiving cavity. The inner bottom surface of the receiving cavity is provided with an optical lens. The outer side surface of the main body is provided with a stepped surface. The upper end surface of the main body is an light outlet surface. The circumferential side surface of the main body and the stepped surface are coated with a light shielding layer. In this way, the light shielding layer has high shielding performance, so that the light emitted by the flash LED lamp can only exit through the light outlet surface, avoiding the dispersion and conduction of the strong light of the flash LED lamp through the shell material combined with it, thereby eliminating the generation of light leakage defects.

[0005] However, the above-mentioned flash lens assembly still has the following shortcomings:

[0006] (1) A flash lens that can avoid light leakage reduces light leakage by aligning the lenses with each other, but the gap between the lenses can cause light to leak out of the gap;
