characterized by the following steps: - Determining actual luminous flux values (E 0i) in respective luminous bands (E1 to E8); - determining desired luminous flux values in respective light bands using a luminous flux for the entire light image - the total luminous flux (E ges) - and the number of light bands; - calculating a desired width value per light band with respect to the desired luminous flux using the total luminous flux (E ges), the number of light bands n, the desired luminous flux per light band, and a height (h LV) of the light image, and - using the calculated width values to change the width of the light band in the light image by changing the light band width on the light conversion means, the height (h LV) of the light image remaining unchanged, wherein calculating the desired width value per light band with respect to the desired luminous flux (E m) further comprising: selecting a light band (LB i) determining an actual width value (b 0i), determining an actual luminous flux (E m) for the selected light band (LBi), comparing the actual luminous flux (E 0i) with the desired luminous flux (E m), increasing or decreasing or maintaining the actual width value (b 0i), depending on whether the actual luminous flux (E 0i) is smaller than the desired luminous flux (E m) or the actual luminous flux (E 0i) is larger than the desired luminous flux (E m) or the actual luminous flux (E 0i) is substantially equal to the desired luminous flux (E m), repeating steps, and with the changed width values until the actual luminous flux (E 0i) is substantially equal to the desired luminous flux (E m), wherein after the change of the luminous band width the dispersion of the luminous flux values is smaller compared to the original luminous flux values of the bands of the same width. - Dividing at least a part of the luminous image into equally sized luminous bands, the number of luminous bands being denoted as n, the number of luminous bands corresponding to the number of laser light sources;
