Abstract

An automotive lighting system () includes an automotive lamp having an LED array () and a lens (). The lens () images a square field of illumination () into rectangular field of illumination () to support adaptive front lighting in an automotive environment (). The lens () includes light-transmissive first, second, and third regions (), and a baffle () adapted to obstruct light from spreading between the light-transmissive first, second, and third regions (). The baffle () is disposed between the LED array () and light receiving surfaces () of the light-transmissive first, second, and third regions (). The lens () enables imaging of an approximately rectangular field of illumination () from a single chip (), reducing cost and cooling needs of adaptive front lighting systems.
