A motor vehicle headlamp comprises a light source of predetermined geometry, and a reflector associated with the light source. The reflector is made by a method that includes the steps of: (a) establishing a reflective base surface having a reference focus and giving a predetermined distribution of the light emitted by a light source having a given geometry and a given position with respect to the reference focus, mainly in the vertical direction, (b) in at least one zone, determining a line passing through all of the points that give the same predetermined horizontal deviation of a theoretical radiation propagated from the reference focus, (c) modifying the base surface so as to put on it, substantially along the line determined in step (b), a striation for horizontal diffusion of the light, (d) making a mould in conformity with this modified surface, and (e) moulding the reflector in this mould.
A method of making a motor vehicle headlamp reflector, the method including the steps of:
A method of making a motor vehicle headlamp reflector having a reflective base surface that is non-parabolic or at least includes one non-parabolic portion and that generates a predetermined distribution of light emitted from a light source, the method including the steps of:
A motor vehicle headlamp comprising a light source of predetermined geometry, a reflector adjacent to said light source for reflecting light therefrom, and a closure glass in front of said reflector and said light source, wherein said reflector defines a reflective base surface that is non-parabolic or includes at least one non-parabolic portion and that generates a predetermined distribution of light emitted from said light source, said non-parabolic portion of said base surface further defining a first and a second notional line delimiting a band of said base surface between them, and wherein light reflected from said first notional line is reflected in an essentially first distinct horizontal angle of deviation and light reflected from said second notional line is reflected in an essentially second distinct horizontal angle of deviation, and said reflector further includes at least one striation in said base surface and within said band for horizontal diffusion of light.
A reflector having a reflective base surface that is non-parabolic or includes at least one non-parabolic portion and that generates a predetermined distribution of light emitted from a light source, the reflector comprising:
