Abstract
A vehicle light system including a light source, a spatial light modulator and a projection device; the light source includes a plurality of light-emitting modules which may be independently controlled; the spatial light modulator includes a plurality of modulation regions in one-to-one correspondence with the light-emitting modules; light emitted by a light-emitting module is incident on a modulation region corresponding thereto; each modulation region includes a plurality of light modulation units; the vehicle light system further includes a control device; according to an input signal, the control device generates a light source control signal, which is used for controlling the light output intensity of each light-emitting module of the light source, and a light modulation signal, which is used for controlling the spatial light modulator, such that the light transmission rate of at least one light modulation unit in any one of the modulation regions reaches an upper limit value.
