[0011] Another object of the present invention is to provide a lens, comprising a lens body, wherein the above-mentioned scale armor structure is provided on the outer surface of the lens body.
[0012] Furthermore, the light-emitting side of the lens body has an inwardly recessed groove, and the light-entering side of the lens body is provided with a receiving groove for accommodating a light source, the middle portion of the bottom surface of the groove protrudes toward the top surface of the groove to form a first protrusion, and the top surface of the receiving groove protrudes toward the bottom surface of the groove to form a second protrusion.

[0036] Please also read Figure 1 , the scale armor structure provided by the embodiment of the present invention is now described. The scale armor structure 1 includes a curved surface (not marked in the figure) and a plurality of connection points 12 randomly set on the curved surface, with any one of the connection points 12 being used as a reference point, and each connection point 12 adjacent to the reference point being connected to the reference point to form a grid line 13, and the number of connection points 12 connected to the reference point ranges from 3 to 10. A grid composed of a plurality of grid lines 13 and a curved surface constitute a grid surface, and a plurality of grid lines 13 divide the curved surface into a plurality of small units, that is, the smallest unit constituting the grid surface is a scale armor surface 11, and each scale armor surface 11 is seamlessly spliced, and each scale armor surface 11 is polygonal. The scale armor structure 1 can be applied to optical devices such as reflectors and lamps of any shape, and is not limited here.
[0037] Optionally, the scale armor structure 1 is a mesh surface formed by seamlessly splicing a plurality of scale armor surfaces 11, and the generation method of the mesh surface includes the following steps:
[0038] 1. Initialize and generate several connection points 12 on the surface.
[0039] 2. Connect several connection points 12 in sequence to form several scale armor surfaces 11.
[0040] 3. Optimize the connection relationship between each connection point 12 so that each connection point 12 is substantially equal to the number of connection points 12 connected to it. Preferably, each connection point 12 is connected to 6 other connection points 12, which is not limited here.
[0041] 4. Optimize the position of each connection point 12 so that the distances between adjacent connection points 12 are approximately equal.
[0042] By optimizing the position and connection relationship of each connection point 12, a plurality of connection points 12 can form a plurality of scale armor surfaces 11 that are different from the traditional regular scale armor structure 1, thereby completely dispersing the light and making the light and the light spot uniform.
[0043] For further information, please also refer to Figure 1 As a specific implementation of the scale armor structure provided by an embodiment of the present invention, each scale armor curved surface 11 is triangular. In this structure, each scale armor curved surface 11 is designed and distributed through the above-mentioned grid curved surface, so that the light reflected by each scale armor curved surface 11 has different irradiation directions, so that the light and the light spot are uniform. In other embodiments, each scale armor curved surface 11 can also be other polygons, such as quadrilaterals, pentagons, etc., which are not limited here.
[0044] Optionally, the scale armor surface 11 is controlled by the boundary and grid lines 13 (i.e., the lines formed by connecting the connection points 12). The shape of the scale armor surface 11 can be changed by changing the position of the connection points 12 on the grid lines 13. The grid lines 13 are generally cubic spline difference curves of the connection points 12.
[0045] For further information, please also refer to Figure 1 As a specific implementation of the scale armor structure provided by an embodiment of the present invention, each scale armor curved surface 11 is set to be inwardly concave or outwardly convex from its center to its edge. This structure can effectively reflect light by setting each scale armor curved surface 11 to be convex or concave, thereby improving the light mixing effect.
[0046] Optionally, each scale armor surface 11 has a convex structure, or each scale armor surface 11 has a concave structure, or a certain proportion of the scale armor surfaces 11 have a convex structure, and the remaining scale armor surfaces 11 have a concave structure. For example: half of the scale armor surfaces 11 have a convex structure, and the other half of the scale armor surfaces 11 have a concave structure; or 30% of the scale armor surfaces 11 have a convex structure, and 70% of the scale armor surfaces 11 have a concave structure, etc. Since the degree of concavity of the convex and concave parts will seriously affect the light spot and the beam angle, it is necessary to layout the scale armor structure 1 based on different light rays to achieve the best light mixing effect. In other embodiments, whether each scale armor surface 11 has a convex structure or a concave structure, and the number of scale armor surfaces 11 with a convex structure and the number of scale armor surfaces 11 with a concave structure can be adjusted according to actual needs, and are not limited here.

Optionally, the difference range of the distance between each reference point and each connection point 12 respectively connected to the reference point is 0.01mm-5mm. Of course, this difference range can be adjusted according to actual needs, and is not a sole limitation here. This structure facilitates the optimization of the degree of concavity, quantity, size, etc. of each scale armor curved surface 11 to achieve the optimal light mixing effect.

By optimizing the position and connection relationship of each connection point 12, a plurality of connection points 12 can form a plurality of scale armor surfaces 11 that are different from the traditional regular scale armor structure 1, thereby completely breaking up the light, and making the light and the light spot uniform.

The scale armor curved surface 11 enclosed by the plurality of grid lines 13 is the smallest unit constituting the grid curved surface. The number of connection points 12 connected to the reference point is limited to a range of 3-10, which can ensure that each scale armor curved surface 11 has a polygonal configuration different from the traditional regular scale armor structure. The shape and position of the light spot formed after the light is reflected by the scale armor structure 1 are random, and there is no regular repetition, that is, the scale armor structure 1 can completely disperse the light. The reflective cup and lens using the above-mentioned scale armor structure 1 have a good light mixing effect, and the light and the light spot are uniform.
[0075] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
