  • Patent number: 10627069
    Abstract: A headlamp for a vehicle. The headlamp uses individual light emitting didoes or LEDs to generate individual light beams, which collectively form a composite beam. Because of manufacturing irregularities, some of the individual beams overlap neighboring beams, and form bright spots within the composite beam, which are not desirable. It is possible to de-focus the individual beams, to thereby spread out the bright spots, and reduce their intensities. However, that de-focusing would conflict with another goal. When the vehicle follows another vehicle, some individual beams which would apply glare to the other vehicle are shut off. But it is desirable that the remaining active individual beams which flank the other vehicle have sharply defined edges. De-focusing would soften the edges. Therefore, one form of the invention selectively de-focuses individual beams only when they are not adjacent individual beams which are active.

  • Patent number: 10094527
    Abstract: 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.
