Abstract
A vehicle lighting device including a light source module, a light valve, a sensing unit, a projection lens set and a control unit. The light source module provides an illumination beam. The light valve is located on a transmission path of the illumination beam, and is capable of being switched to different states for adjusting the illumination beam. The sensing unit senses the front of the vehicle lighting device and generates a signal. The projection lens set is disposed on an optical path of the illumination beam for projecting at least a portion of the illumination beam. The control unit is electrically connected to the light valve and the sensing unit for receiving the signal. The control unit controls the light valve to adjust a light distribution pattern of the illumination beam according to the signal, and project the illumination beam to the front through the projection lens set.
