1. A method for determining the detection distance prevailing in a given direction of a light signal comprising several light spots with an established surrounding radiant density per unit area with the following steps:

  • measurement of the radiant density per unit area or light intensity prevailing in the given direction of each individual light spot andcalculation of the detectability and readability distance based on the measured radiant densities or light intensities,whereinthe calculation of the detection distance is performed with the help of the threshold value for the total radiant density per unit area or the total light intensity of the light signal which is obtained through multiplication of the measured radiant density per unit area or light intensity of an individual light spot with a power of the number of light spots and with a correction factor.
