Abstract:
The invention relates to a projection device (1) for a motor vehicle headlight, wherein the projection device (1) is configured to project light from at least one light source (2) associated with the projection device (1) in a region in front of a motor vehicle in the form of at least one light distribution, wherein a light-impermeable coating consists of partial layers arranged in an at least planar manner one on top of the other, specifically a reflective metal first partial layer (6) and a second partial layer (6″) consisting substantially of black light-absorbing paint, wherein the first partial layer (6′) is arranged between the input lens system (3) and the second partial layer (6″).
