BEACON TYPES 4 types of Visual signalling products are generally offered, providing différent levels of signalling effects STEAOY BEACONS Lowest signalling effect the light intensity ot a steady or m gênerai a signal teacor vanes with distance belween signaling device and viewer po^erof light source use of différent lens types (by using a particularly designed -Fresner-ribbing pattern the light spol in a beacon is dislributed over the whole lens height and by thaï the best signalling effect achieved) FLASHING BEACONS Increase the attention by aeriodic swilchng on'off of the tight source, the fashing frequency is usually between 1 - 2 Hz. Powerful beacons cycle usually slower as the afterglow time is getting longer the nore powerful a bulb or halcgen bulbis. \/À~ 'Xj: f * y ROTATING MIRROR BEACONS By divertising a light spot in a particular direction and by focussing îhe light a rotaiing light beam s produced The moving light causes high attention; by using différent rotation speeds :he attention can be further increased. Rotating mirror beacons use smootri lenses for achieving the maximum visual sgnalling effect. r * " m- 4 » i 4 f k \ STROBE OR XENON BEACONS l * f i i s t # -:o:- *1 Electrical energy is stored in a capacitor and then released instantly when flashing/sirobing once via the slrobe/xenon tube. Very short flashing tirres (few milliseconds) and a very intense light impulse is achieved resu ting in highest skjnaling eftect and attention By using a ribbed «Fresner lens the signalling effect to the side is increased.
