Abstract
Provided is an adaptive front light system (AFLS) for a vehicle. The AFLS comprising one or more light-emitting diode (LED) lamp units and a housing which accommodates the LED lamp units, wherein each of the LED lamp units comprises one or more LEDs as its light source and a reflector which reflects light emitted by the light source so that the reflected light can be directed forward, and said adaptive front light system is operable to form different beam patterns by selectively turning on or off the lamp units, and wherein one or more reflectors of the lamp units comprise a multi-face reflector including a plurality of cells having different curvature radiuses or focal points.
