The present invention relates to a lighting device for lighting the cabin of a motor vehicle, the device comprising an elongate light source disposed inside a housing. According to the invention, the lighting device further comprises: two windows transparent to the light flux emitted by the source, the windows being spaced apart from each other and comprising a top window through which light radiation is emitted in a generally horizontal direction, and a bottom window through which light radiation is emitted generally downwards; a first directional light reflector disposed between two respective first edges of the windows; and a second directional light reflector disposed between the two respective other edges of the windows; the directional light reflectors having shapes that combine to guide the light flux emitted by the source towards the transparent windows.
