1. Illuminating device including a plurality of light sources mounted on a deck, characterized in that it includes:

  • a first set of light sources placed in a central zone of the deck; and

    a second set of light sources placed in a peripheral zone of the deck,the light sources of one of the sets being configured for transmitting data by modulation of visible light, the light sources of the other set not being configured for transmitting data by modulation of visible light, the light sources of at least one of the sets being associated with at least one fixed convergent first lens positioned on the axis of one of said sources,the illuminating device being such that it furthermore includes, arranged parallel to the deck and superposed on the light sources and first lenses;

    a first element adapted to the central zone including a first set of divergent lenses, each of the lenses being arranged on the axis of a light source of the central zone; and

    a second element adapted to the peripheral zone including a second set of divergent lenses, each of the lenses being arranged on the axis of a light source of the peripheral zone,the first and second elements being further adapted to be able to move one relative to the other along a path perpendicular to the deck and mechanically coupled so that movement of the first element in a first direction is coupled with displacement of the second element in a second direction opposite to the first direction.
