Abstract (en)
[origin: WO2004062942A1] The inventive safety device comprises a transparent substance layer (4) having a refraction index and a thickness suitable for forming a waveguide and containing at least one type of a photoluminescent product. One of the faces of said waveguide layer is provided with a light-extraction pattern (10) which locally disrupts a waveguide effect.
