Description

Technical Field

[0001] This application belongs to the field of lighting devices. Specifically, it relates to a lens module with a small-angle light output. Background Art

[0002] Currently, the lighting fixture market is starting to pursue miniaturization of lighting fixtures. In addition to saving the material cost of lighting fixtures, it can also reduce the layout density of lighting fixtures in the installation scenario, giving people a more comfortable and intuitive visual effect. In addition, in lighting fixtures such as flashlights, the miniaturization of the optical lens module can enable consumers to carry them conveniently.

[0003] On the market, a double convex lens is mostly used. In order to achieve the collimation effect of the light rays of the light source, the diameter of the first lens used is much larger than that of the second convex lens. When this type of optical solution is adopted for lighting fixtures, the volume of the lamp body will increase accordingly, which is not conducive to portability and reducing the cost of lighting fixtures. Summary of the Utility Model

[0004] In order to overcome the above-mentioned shortcomings in the prior art, the purpose of this application is to provide a lens module with a small-angle light output, which has a simple and compact structure, a small volume, and reduces the cost of lighting fixtures.

[0005] The technical means adopted by this application to solve the above technical problems is:

[0006] This application provides a lens module with a small-angle light output, including:

[0007] A first convex lens, on the side of the first convex lens away from the convex surface, there is a first installation groove;

[0008] A second convex lens, on the side of the second convex lens away from the convex surface, there is a second installation groove, and the second convex lens is installed in the first installation groove;

[0009] A light source, and the light source is installed in the second installation groove.

[0010] Preferably, the radius of the second convex lens is smaller than the radius of the first convex lens.

[0011] Preferably, the first installation groove has a spherical structure.

[0012] Preferably, the second installation groove has a spherical structure.

[0013] Preferably, the first convex lens and the second convex lens are arranged in alignment.

[0014] Compared with the prior art, the lens module with small-angle light output of the present application is provided with a first convex lens and a second convex lens. The first convex lens is provided with a first mounting groove, and the second convex lens is provided with a second mounting groove. By installing the second convex lens into the first mounting groove and installing the light source into the second mounting groove, while the three points are on the same line, the radius of the first convex lens is reduced, and thus the overall volume of the lamp is reduced; the structure is simple and compact, and the material cost of the lamp is saved.
