Abstract (en)
[origin: WO2015193575A1] The invention relates to a lighting and/or signalling device (20) comprising a plurality of adjacent light sources (39) capable of emitting light beams (10), a reflector (50) arranged facing the plurality of light sources (39) and capable of reflecting the light beams emitted by the plurality of light sources (39) and a screen (60) capable of receiving and diffusing the light beams (10) reflected by the reflector (50), characterised in that said reflector (50) is shaped so as to have a single concave reflecting surface (51), extending facing the plurality of light sources (39) and in which the dimensions (L, t, H and R) are suitable for illuminating at least one predefined pattern (61 or 62) on the screen (60), the reflective surface (51) of the reflector (50) including a curve with variable radius (R) following a parabolic profile, and the reflector being provided in the form of a sheet obtained by profiling a plastic material; the reflective surface (51) being a layer of light-reflecting material added to the concave portion of the reflector (50) or coloured in the mass.
