Automotive lamp optical system with light diffusive projection lens

A headlamp assembly of an automotive vehicle, the headlamp assembly comprising:

• a number of low beam modules configured to generate a low beam distribution;
• a number of high beam modules configured to generate a high beam distribution, wherein at least one of the low beam modules and the high beam modules includes an optical system comprising:
• a number of first optical elements that are configured to reflect light emitted from a number of first light sources that are configured to perform a first lighting function;
• a number of diffusive optical elements arranged at a downstream location of said first optical elements that are configured to project a light beam from said first optical elements that are configured to perform the first lighting function, wherein said diffusive optical elements form an assembly of a second optical element wherein a single projection lens is made of a number of different light diffusive materials;
• and
• a number of secondary light sources, wherein the second optical element is configured to receive light emitted from said secondary light sources, which are configured to perform a second lighting function by scattering the light received from said secondary light sources.
