Abstract:
An automotive headlight is disclosed including: an optical unit including a plurality of optical elements, each optical element having a different central direction; a segmented light-emitting diode (LED) chip including a plurality of LEDs that are separated by trenches formed on the segmented LED chip and arranged in a plurality of sections, each section being aligned with a different respective optical element, and each section including at least one first LED and at least one second LED; and a controller configured to: apply a forward bias to each of the first LEDs, apply a reverse bias to each of the second LEDs, and change a brightness of the first LEDs in any section based on a signal generated by the second LED in that section.
