An optical system and an interior lighting device for a motor vehicle including a light source coupled to such an optical system. The optical system includes a first portion of an optical assembly that allows a real image of the light source to the enlarged and projected into proximity to a diffuser of the optical system. The optical assembly also includes a second portion that plays the role of a projecting optic to project out of the optical system a real image of the of the light source formed in proximity to the diffuser. The optical system allows a luminance of the light source of the interior lighting device to be decreased while preserving its pixelization, allowing light sources based on light-emitting diodes and driven with a high-amperage electrical current to be used in motor-vehicle passenger compartments without any risk to the occupants.
