Abstract: An automotive lighting system (41) includes an automotive lamp having an LED array (14) and a lens (34). The lens (34) images a square field of illumination (101) into rectangular field of illumination (48) to support adaptive front lighting in an automotive environment (28). The lens (34) includes light-transmissive first, second, and third regions (64, 66, 68), and a baffle (70) adapted to obstruct light from spreading between the light-transmissive first, second, and third regions (64, 66, 68). The baffle (70) is disposed between the LED array (14) and light receiving surfaces (98, 104, 110) of the light-transmissive first, second, and third regions (64, 66, 68). The lens (34) enables imaging of an approximately rectangular field of illumination (48) from a single chip (12), reducing cost and cooling needs of adaptive front lighting systems.
