Specifically, as shown in fig. 2-5, the combined optical lens 10 includes a light-emitting surface 11 and an incident surface 12, where the light-emitting surface 11 includes at least two light-emitting areas, and a focal point corresponding to each light-emitting area is located on the same optical axis; the light-emitting areas are spliced into a complete light-emitting surface 11, and a splice between each light-emitting area and the adjacent light-emitting area, namely, a position shown by a broken line in fig. 4 and 5, is integrally formed, if the light-emitting surfaces 11 are completely fused to form a whole, the light-emitting surface 11 at the splice is of a smooth transition surface structure; the light-emitting surface 11 is an integrally formed aspheric-like structure, and is specifically a smooth and complete curved surface, the incident surface 12 is a planar structure, and the combined optical lens is integrally in a plano-convex lens structure.
As shown in fig. 4, the light-emitting surface 11 is circular, and includes a first light-emitting surface 121, a second light-emitting surface 122, and a third light-emitting surface 123, wherein the first light-emitting surface 121 and the second light-emitting surface 122 are spliced to form a semicircle of the light-emitting surface 11, and the third light-emitting surface 123 is semicircular and is spliced to form the light-emitting surface 11 with the first light-emitting surface 121 and the second light-emitting surface 122; the focal point corresponding to the first light emitting area 121 is a first focal point 110, the focal point corresponding to the second light emitting area 122 is a second focal point 120, and the focal point corresponding to the third light emitting area 123 is a third focal point 130; the first focus 110, the second focus 120, and the third focus 130 are on the same optical axis, and the first focus 110 and the second focus 120 coincide.
When the light-emitting surface 11 of the combined optical lens 10 is composed of three light-emitting surface areas, the first light-emitting surface area 121 and the second light-emitting surface area 122 are located on one side of the upper semicircle of the combined optical lens 10, and the focuses are overlapped, so that the light projected from the first focus 110 and the second focus 120 to the incident surface 12 can be overlapped, so as to improve the illumination brightness of a designated illumination area, and the brightness of the illumination area can be adjusted; the third light emitting area 123 is located at one side of the lower semicircle of the combined optical lens 10, and the focal point thereof may or may not coincide with the two focal positions; when the light beam is overlapped with the two focuses, the light rays of the three light emitting areas can be overlapped according to the needs, so that the brightness in the lighting area can be adjusted at more levels; when the light source is not overlapped with the two focuses, the illumination area of the light rays of the third light emitting area is different from the illumination areas of the light rays of the two light emitting areas, so that the effects of switching the illumination areas and adjusting the brightness can be achieved.
As shown in fig. 5, the light-emitting surface 11 is circular, and includes a first light-emitting surface 121, a second light-emitting surface 122, a third light-emitting surface 123 and a fourth light-emitting surface 124, wherein the first light-emitting surface 121 and the second light-emitting surface 122 are spliced to form a semicircle of the light-emitting surface 11, and the third light-emitting surface 123 and the fourth light-emitting surface 124 are spliced to form another semicircle of the light-emitting surface 11; the focal point corresponding to the first light emitting area 121 is a first focal point 110, the focal point corresponding to the second light emitting area 122 is a second focal point 120, the focal point corresponding to the third light emitting area 123 is a third focal point 130, and the focal point corresponding to the fourth light emitting area 124 is a fourth focal point; the first focus 110, the second focus 120, the third focus 130 and the fourth focus are on the same optical axis, and the first focus 110 and the second focus 120 coincide, and the third focus 130 and the fourth focus coincide.
When the light-emitting surface 11 of the combined optical lens 10 is composed of four light-emitting surface areas, the first light-emitting surface area 121 and the second light-emitting surface area 122 are located on one side of the upper semicircle of the combined optical lens 10, and the focuses are overlapped, so that the light projected to the light-emitting surface 11 from the first focus 110 and the second focus 120 can be overlapped, so as to improve the illumination brightness of a designated illumination area, and the brightness of the illumination area can be adjusted; the third light-emitting area 123 and the fourth light-emitting area 124 are located on one side of the lower semicircle of the combined optical lens 10, and the focal points thereof may or may not coincide with the two focal positions; when the light beam is overlapped with the two focuses, the light rays of the four light emitting areas can be overlapped according to the needs, so that the brightness in the lighting area can be adjusted at more levels; when the light beam does not overlap with the two focuses, the illumination areas of the light beams of the third light-emitting area 123 and the fourth light-emitting area 124 are different from the illumination areas of the light beams of the two light-emitting areas, so that the effects of switching the illumination areas and adjusting the brightness can be achieved.
The combined optical lens 10 with various focal lengths is made of plastic, PMMA and/or PC. Because the combined optical lens 10 is required to be integrally formed, and has high requirement on the integrity, the combined optical lens is made of only one material, and the thickness and uniformity of the incident surface 12 are relatively low although the basic effect requirement can be met; therefore, in order to further improve the obvious switching between the illumination area and the illumination brightness, it is preferable to use a plurality of different materials to manufacture each light emitting area, and then combine each light emitting area into a whole, because the refraction effects of the materials on the light are different, it is ensured that the whole thickness of the incident surface 12 and the light emitting surface 11 of the combined optical lens 10 is uniform while different refraction effects of different light emitting areas are achieved.
The distance between the individual focal spots is 1mm-50mm. Because the light-emitting surface 11 and the incident surface 12 of the combined optical lens 10 are integrally and smoothly transited, that is, the thicknesses of the light-emitting areas are not particularly obvious even if the thicknesses of the light-emitting areas are different, the focal positions of the combined optical lens 10 are more concentrated, and the distances between the focal points corresponding to the light rays of different illumination areas are more approximate; in this embodiment, an optimal numerical range is provided that can ensure that the lighting device is more compact and that does not affect the distance between different focuses of the actual application effect of the combined optical lens 10.
