Abstract

To form a light distribution pattern having a light illuminance distribution desirable for a vehicular lamp while reducing the temperature bias of a liquid crystal element. A vehicular lamp system capable of variably setting an irradiation pattern of light irradiated to the surroundings of an own vehicle including a light source, a first optical system for making uniform the intensity distribution of light from the light source, a liquid crystal element for modulating light emitted from the first optical system to form an image, a driving unit for driving the liquid crystal element, and a second optical system for projecting the image formed by the liquid crystal element, wherein the vehicular lamp system has a central axis in which the image incident on the plane including the central axis is projected at a relatively large enlargement ratio as it is farther from the central axis.
