Vehicle headlight

A vehicle head lamp comprising:

• a spatial light modulator having a light source;
• and a control device that controls the spatial light modulator, wherein
• the vehicle head lamp forms a desired light distribution pattern by radiating light emitted from the light source forward via the spatial light modulator,
• a high luminous intensity region and a low luminous intensity region that is adjacent to an outer edge of the high luminous intensity region and has a luminous intensity lower than a luminous intensity of the high luminous intensity region are formed in the desired light distribution pattern to be irradiated by controlling the spatial light modulator by the control device,
• the low luminous intensity region is configured such that the luminous intensity decreases gradationally from the outer edge of the high luminous intensity region toward an outside of the low luminous intensity region, and
• the control device controls the spatial light modulator so as to relatively change at least one of sizes, luminous intensities, and positions of the high luminous intensity region and the low luminous intensity region in accordance with a traveling condition of a vehicle on which the control device is equipped.
