Embodiment Construction

[0029] Below in conjunction with specific embodiment, content of the present invention is described in further detail:

[0030] In order to achieve the purpose of the present invention, a high and low double-threaded lens includes: a lens body with a light incident surface and a light exit surface; the light incident surface or the light exit surface of the lens body is equipped with first concentric circular threads 1 and 1 arranged at intervals. The second concentric circular thread 2, the first concentric circular thread 1 and the second concentric circular thread 2 have height differences along the light incident and light exit directions of the lens body.

[0031] Such as figure 2 As mentioned above, the second concentric circular thread 2 is more protruding than the first concentric circular thread 1 .

[0032] The beneficial effect of adopting the above technical solution is: change the thread of the traditional single lamp, the traditional thread is on the same plane...

Abstract

The invention discloses a high-low dual-threaded lens. The high-low dual-threaded lens comprises a lens body which is provided with an incident face and an emergent face; the incident face or the emergent face of the lens body is provided with a first concentric circle thread and a second concentric circle thread which are distributed in a spaced mode; and a height difference exists between the first concentric circle thread and the second concentric circle thread in the incident direction and the emergent direction of the lens body, and the range of the height difference is 0.05-0.5 mm. Diameters corresponding to the first concentric circle thread are sequentially arranged in an arithmetic progression form, and the diameters corresponding to the first concentric circle thread are sequentially arranged in an arithmetic progression form. By adoption of the high-low dual-threaded lens, light of a single light source forms a dual-light-source effect, and the layering sense of emergent light is improved.

Description

technical field [0001] The invention relates to a flash lens, in particular to a high and low double threaded lens. Background technique [0002] With the emergence of cameras, the flashlight of mobile phones is a useful device for improving brightness as a lighting device for taking pictures. The flashlight cover matched with the flashlight can further increase the brightness. The single flash lamp cover is commonly used on the mobile phone flash, but the optical efficiency of this lamp cover is low, and the appearance effect is single. Even though some flash lampshades have spliced ​​threads, the threads still overlap on the same plane, which makes the level of the transmitted light lower. Contents of the invention [0003] The problem to be solved by the present invention is to provide a high and low double threaded lens, which can form a double light source effect on the light of a single light source, and improve the sense of layering of the emitted light. [0004] ...
