Beam characteristics of the LEDs on the sounder
beacon interbase (DC 32 V)
To indicate the effective luminous intensity I
eff
of the FDSB229 interbase (in
accordance with the Blondel-Rey law), a polar coordinate system is used based on
azimuth and elevation. The zero point of the azimuth (0°) relates to the position of
the internal alarm indicator in the interbase FDSB229.
