METHOD FOR CORRECTING A LIGHT PATTERN AND AUTOMOTIVE LIGHTING DEVICE ASSEMBLY

A method for correcting a light pattern provided by a first lighting device and a second lighting device. The first lighting device projects a first light pattern and the second lighting device projects a second light pattern. There is an overlapping zone between the first light pattern and the second light pattern. The method includes the steps of, for each lighting device, dividing the light sources in groups, each group being associated to a projection distance, calculating an overlapping region as a function of the projection distance, calculating a number of affected light sources for each group as a function of a representative dimension of the overlapping region and attenuate the intensity of the light emitted by the affected light sources in each group of each lighting device, following a monotonic attenuation pattern from 100% attenuation in the first affected light source to 0% in the last affected light source. The invention also provides an automotive lighting device assembly with control means to perform the steps of this method.
