ABSTRACT:
The invention relates to a method for establishing a light beam (CLB) with substantially constant luminous intensity comprising the steps of establishing a light beam (LB) by means of a light source (SAL) and controlling an attenuation of said light beam (LB) on the basis of occurrences of luminous intensity peaks (IP) in said light beam (LB).
