Abstract
The subject invention comprises an adaptive front lighting system (“AFS”) utilizing at least one light emitting diode (“LED”) as a light source and a means for moving the LED to achieve AFS functionality. An exemplary embodiment of the subject invention comprises a plurality of LEDs positioned and located on a LED carrier. The LED carrier is mechanically connected to at least one actuator that causes the LED carrier and LEDs to move. A controller is used to cause the actuator to move the LEDs. In this manner, this exemplary embodiment adjusts the light beam and creates the desired light beam pattern. Other exemplary embodiments of the subject invention pivotally connect the LEDs to the lens and to each other and utilize the actuator and controller to adjust the light beam. Another exemplary embodiment positions the LEDs in a spherical surface and connects them to the actuator by an extension in order to adjust the light beam.
