[0031] The first array surface 11, the second array surface 12 and the third array surface 13 are arranged in sequence and connected to each other; the reflection of light is achieved by the combination of the first array surface 11, the second array surface 12 and the third array surface 13, so that more light control methods are provided, the control of the array surface is increased, the controllability of light is multiplied, and the control of light is more precise.

[0032] Alternatively, the first array surface 11, the second array surface 12 and the third array surface 13 are arranged in sequence and at intervals; the reflection of light is achieved through the combination of the first array surface 11, the second array surface 12 and the third array surface 13, so that more light control methods are provided, the control of the array surfaces is increased, the controllability of light is multiplied, and the control of light is more precise.

[0033] The light reflection angles of the first array surface 11, the second array surface 12 and the third array surface 13 are arranged inconsistently; the combination of the first array surface 11, the second array surface 12 and the third array surface 13 realizes reflection of light at different angles, which provides more light control methods, increases the control of the array surfaces, multiplies the controllability of light, and makes the light control more precise.

[0036] Alternatively, the light reflection angle of the second array surface 12 and the light reflection angle of the third array surface 13 are arranged inconsistently, and the light reflection angle of the first array surface 11 is arranged consistently with the light reflection angle of the second array surface 12 or the light reflection angle of the third array surface 13; realizing reflection of light at different angles provides more ways to control the light, increases the control of the array surface, multiplies the controllability of light, and makes the control of light more precise.

[0037] The output portion 1 has an inner output surface and an outer output surface. The inner output surface is arranged in an arched arc shape along the direction away from the light input portion 3, the outer output surface is butt-jointed with the inner output surface, and the outer output surface surrounds the inner output surface. The outer output surface is arranged in an annular enclosure, and the cross-sectional area of ​​the outer output surface is gradually increased along the direction away from the light input portion 3; the light input portion 3 reflects light to the inner output surface, and the outer output surface has a first array surface 11, a second array surface 12 and a third array surface 13.

[0038] In this way, part of the light is directly reflected by the light input part 3 and projected outward through the inner output surface, and part of the light is reflected by the light input part 3 to the outer output surface, and then reflected by the outer output surface to the output part 1 and projected outward. The two parts of the light are projected outward after reflection to form a light spot; the light emitted from the outer output surface is projected by the first array surface 11, the second array surface 12 and the third array surface 13 respectively, which provides more ways to control the light, multiplies the controllability of the light, and makes the control of the light more precise.

[0041] Alternatively, the first array surface is a light surface that is smooth and translucent, the second array surface has multiple second micro-facets that are arranged in a tiled pattern, the third array surface has multiple third micro-facets that are arranged in a tiled pattern, and the light reflection angles of the second micro-facets and the third micro-facets are arranged inconsistently.

[0042] In this way, through the coordinated regulation of the first array surface, the second array surface and the third array surface, the controllability of light is multiplied, making the control of light more precise.

[0045] The inner emission surface is arched to be arranged corresponding to the second array surface 12; thus, the projection effect of the light is improved and the uniformity of the light spot is improved.

[0046] The first array surface 11, the second array surface 12 and the third array surface 13 are respectively arranged in a ring shape, and the cross-sectional areas of the first array surface 11, the second array surface 12 and the third array surface 13 are gradually increased along the direction away from the light input portion 3; in this way, the light passing through the reflection surface 2 is reflected by one of the first array surface 11, the second array surface 12 and the third array surface 13, so that the reflection of the light is guaranteed. At the same time, the increase in the cross-sectional area improves the reflection effect, increases the controllability of the light, and makes the light control more precise.

[0047] The second array surface 12 includes a plurality of array layers, which are arranged in a ring shape. Each array layer is sequentially connected and arranged in an array. The array layer includes a plurality of second micro-facets, each second micro-facet is first connected and arranged in a ring shape.

[0050] In this way, more ways to control light are provided, the control of the array surface is increased, the controllability of light is multiplied, and the control of light is made more precise.

[0051] The first array surface 11 , the second array surface 12 and the third array surface 13 are arranged in an integrated manner, which is convenient for production and manufacturing and helps to reduce costs.

[0052] Furthermore, the first array surface 11, the second array surface 12 and the third array surface 13 are arranged in a curved surface shape, which is convenient for reflecting light.

[0053] like Figure 5 As shown, this is a schematic diagram of the output light path of the lens of the prior art. At point B, since the output surface is a single curved surface, the total reflected light passes through five surfaces and freely combines to form a complete light spot. There are only 120 control methods.
