US Patent 10094527 Vehicle low beam headlamp having partially transmissive shutter region

A projection headlamp (12) has a reflector (28) reflecting light emitted from a light engine (20); a projector lens (30) projecting reflected light from the reflector (28); and a shutter (22) disposed between light engine (20) and projector lens (30), the shutter (22) having an upper edge (44) defining a cut-off to generate a low beam pattern by obscuring a portion of the projector lens (30) from the reflected light and to selectively emit the reflected light through the projector lens (30) in a low-beam light distribution pattern. The shutter (22) further includes a partially light-transmissive shutter bump (56) extending above the upper edge (44) which attenuates light emitted from the projector lens (30) in a predefined area of the low-beam pattern. Light intensity at the 0.86D, 3.5L NHTSA test point (112) is attenuated to below maximum photometric intensity (12,000 candela), avoiding glare.
