Motor vehicle lighting device and method for improved matrix beam uniformity generation

A headlamp of a motor vehicle that uses individual light emitting diodes or LEDs to generate individual light beams, which collectively form a composite beam where some of the individual beams overlap neighboring beams because of manufacturing irregularities and form bright spots within the composite beam, which are not desirable. It is possible to de-focus the irregularities from individual beams to thereby spread out the bright spots, and reduce their intensities with another inventive goal to selectively defocus individual beams and soften the edges that apply glare to surrounding vehicles when individual beams are not adjacent individual beams or individual beams that are active and flank surrounding vehicles to be shut off.
