Abstract

The invention relates to an illuminating device including a plurality of light sources mounted on a deck, the device being such 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 each being suitable 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 said sources.

Claims

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 suitable for transmitting data by modulation of visible light, the light sources of the other set not being suitable 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 said sources, the 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.

2. The illuminating device according to claim 1, characterized in that the light sources are LEDs.

3. The illuminating device according to claim 1, characterized in that the first and second elements are translationally movable along an axis perpendicular to the deck.

4. The illuminating device according to claim 3, characterized in that it includes an adjusting mechanism suitable for applying a translation along an axis perpendicular to the deck to at least one of the sets of divergent lenses.

5. The illuminating device according to claim 2, characterized in that the first and second elements are translationally movable along an axis perpendicular to the deck.

6. The illuminating device according to claim 5, characterized in that it includes an adjusting mechanism suitable for applying a translation along an axis perpendicular to the deck to at least one of the sets of divergent lenses.
