<p>The lens (202) has a transparent material volume comprising a strip (210) with an input diopter (204), where the strip is made of a material with refraction index (n3). A complementary part (212) is coupled to the strip, and includes an output diopter (206). The part includes refraction index (n1) different from refraction index of the strip, so that the lens includes an intermediate diopter (214) between the strip and the complementary part. The output diopter is configured, so that an effective focal spot (f) of the lens is located on the input diopter. An independent claim is also included for a lighting module for a car.</p> |
