Shallow indicator light for a motor vehicle

Claim 1

An indicator light for a motor vehicle, the light being of the type comprising a substantially point light source and a flat closure glass situated in front of the source, together with beam-forming means for forming a beam of light rays propagating along a given general emission direction of the light, said beam-forming means comprising: a set of deflector zones which are generally in the form of concentric rings on the glass, each zone being formed by a set of narrow prisms all having the same profile within each zone; and a generally flat or concave mirror disposed behind the light source and comprising a set of reflecting zones homologous to the deflecting zones of the glass, each reflecting zone comprising a set of sloping rings inclined to reflect light rays from the source towards a homologous deflecting zone of the glass, with the average direction of said reflected rays being different from the average direction of the light rays emitted directly from the source to the same deflecting zone, and with the profile of the prisms in each deflecting zone being designed as a function of said two average directions in order to deflect said light rays so that they propagate in a direction close to said general emission direction.
