1. A motor vehicle indicator light, comprising:
- a light source being substantially a point source;
a cover glass; and
an intermediate screen between the light source and the cover glass for directly receiving light from the light source;
the screen comprising a series of optical cells, each of said cells having an internal face facing said light source and an external face facing said cover glass, the internal face of each of said cells defining a curved surface for straightening and spreading the light, and the external face of each of said cells defining a set of at least two transparent flat facets, the facets being angled with respect to each other.

Abstract
An indicator light for a motor vehicle has a point source, an intermediate screen which receives the light directly from the source, and a cover glass outside the screen. The intermediate screen comprises a series of optical cells, each of which has, on an internal face, a curved surface for straightening and spreading the light. Each cell further has, on an outer face, a set of at least two flat facets which are oblique with respect to a plane of the intermediate screen.

11. A motor vehicle indicator light, comprising:
-
a source of light;
a cover glass, and an intermediate screen between the source of light and the cover glass for receiving light from the source of light; and
the intermediate screen comprising a series of optical cells, each of said cells having an internal face facing said source of light and an external face facing said cover glass, the internal face defining a curved surface for straightening and spreading the light, and the external face defining a set of two transparent flat facets, the two facets being angled with respect to each other for adjusting the spread of the light passing through the two facets. - View Dependent Claims (12, 13, 14, 15)

16. A motor vehicle indicator light, comprising:
-
a source of light;
a cover glass; and
an intermediate screen between the source of light and the cover glass for receiving light from the source of light; and
the intermediate screen comprising a series of optical cells, each of said cells having an internal face facing said source of light and an external face facing said cover glass, the internal face defining a curved surface for straightening and spreading the light, and the external face defining a set of two transparent flat facets, the two facets being angled with respect to each other for adjusting the spread of the light passing through the two facets, and the external surface defining relief facets slightly inclined with respect to a general direction of emission of the light, the relief facets laterally bounding the facets of the set.

17. A motor vehicle indicator light, comprising:
-
a source of light;
a cover glass; and
an intermediate screen between the source of light and the cover glass for receiving light from the source of light; and
the intermediate screen comprising a series of optical cells, each of said cells having an internal face facing said source of light and an external face facing said cover glass, the internal face defining a curved surface for straightening and spreading the light, and the external face defining a set of two transparent flat facets, the two facets being angled with respect to each other for adjusting the spread of the light passing through the two facets, and the set further comprising a central facet extending substantially at right angles to a general direction of the emission light, the two angled facets lying on either side of the central facet and being symmetrical with respect to a median line of the corresponding optical cell.
