Abstract:
A motor vehicle headlight assembly comprisingan elongated reflector (3) having a longitudinally extending focal line (F) and a transverse cross-section, said transverse cross-section being at least approximately in the form of a flattened parabola;an elongated gas discharge tube (2) extending within said reflector along said focal line (F) and acting as a source of light reflected by said elongated reflector (3); anda light guiding plate (4) arranged in front of the reflector (3) and through which the light from the reflector passes;wherein said transverse cross-section of said elongated reflector (3) comprises two parabolic segments (3a,3b) arranged on opposite sides of said focal line (F) respectively, said parabolic segments being angularly displaced relative to each other and from corresponding positions in a purely parabolic cross-section, so that said transverse cross-section is at least approximately in the form of said flattened parabola.
