Kind Code:
A1
Abstract:
A lamp unit (10) that comprises a first light source (12), a second light source (14), a spatial light modulator (16) that modulates incident light, a first optical system (18) that is provided on an optical path that is between the first light source and the spatial light modulator and is configured such that light emitted from the first light source is directed toward the spatial light modulator, and a second optical system (20) that is provided on an optical path that is between the second light source and the spatial light modulator and is configured such that light emitted from the second light source is directed toward the spatial light modulator. The first light source (12) and the second light source (14) are configured such that a first area in which light emitted from the first light source (12) shines on the spatial light modulator (16) and a second area in which light emitted from the second light source (14) shines on the spatial light modulator (16) partially overlap.
