Abstract: A vehicle headlight device is disposed with an optical lens group to concentrate light emitted from a light source as incident light, the image sensor detects a dynamic image in front of the vehicle and sends the image to an image process and control component for analyzing and processing to obtain corresponding control signal, the control signal controls an optical switch array device to process the incident light by spatial distribution modulation for obtaining an emission light with an optical distribution pattern corresponding to the dynamic image, therefore it is unnecessary to turn on/off the light source frequently but still can reinforce, weaken or prevent light projected on target areas in front of the vehicle, the driver can achieve the optimum view without affecting the vehicle ahead. Moreover, the invention further provides a vehicle such as a car adopting the vehicle headlight device.
