The combined optical lens 10 with multiple focal lengths is made of plastic, PMMA and/or PC. Since the combined optical lens 10 is required to be integrally formed and has a high requirement on the integrity, it is made of only one material, and although the above basic effect requirement can be met, the thickness and uniformity of the incident surface 12 are relatively low; therefore, in order to further improve the obvious switching between the illumination area and the illumination brightness, a more preferable mode is to use a plurality of different materials to respectively manufacture each light-emitting surface area, and then to fuse each light-emitting surface area into a whole, because the refraction effects of the materials on the light are not different, the thickness of the whole incident surface 12 and the whole light-emitting surface 11 of the combined optical lens 10 can be ensured to be uniform while the different light-emitting surface areas have different refraction effects.
The distance between the focal points is 1mm-50 mm. Because the light emitting surface 11 and the incident surface 12 of the combined optical lens 10 are in smooth transition as a whole, that is, even though the thicknesses of the light emitting surface regions are different, the thicknesses are not particularly obvious, the focal positions of the combined optical lens 10 are more concentrated, and the distances between the corresponding focuses of the light rays in different illumination regions are closer; the embodiment provides an optimal numerical range of distances between different focuses, which can ensure a more compact structure of the lighting device and does not affect the practical application effect of the combined optical lens 10.
