Strobe beacons emit an intense light pulse by flashing very quickly at intervals of milliseconds. This light pulse achieves the best signalling effect and attracts maximum attention.
Xenon strobe beacon
The xenon strobe beacon stores electrical energy in a capacitor and pushes it out through a xenon flashtube in bursts, which generates the light pulse.
LED strobe/multi strobe beacon
Auer Signal is one of the few suppliers of innovative LED multi strobe beacons. These LED strobe/multi strobe beacons use state-of-the-art high-power LEDs as the light source. Although an LED multi strobe beacon does not emit the same amount of light as a xenon strobe beacon at the peaks, it can compensate for the lower light output with a sequence of light pulses, which attract much more attention. The LED multi strobe beacon is therefore able to match the excellent signalling effect. Unlike xenon strobe beacons, LED strobe/multi strobe
beacons afford all of the advantages of LED technology, which include a very long service life, much greater efficiency and unparalleled resistance to vibrations.
Rotating mirror beacons
In rotating mirror beacons, the light source is surrounded by a hemispherical mirror, which focuses the light point in a certain direction as it rotates, creating a rotating beam of light that attracts a lot of attention. The signalling effect can be improved even further by adjusting the speed of rotation.
Flashing beacons attract attention by the light source being switched on and off periodically. Given that flashing light stimuli are more clearly visible than those that are constantly on, they are ideal for applications for which the extreme warning effect of a strobe beacon is unnecessary yet good visibility is still required.
The flash frequency of flashing beacons is usually 1-2 Hz.
Steady beacons emit a constant light signal and possess the weakest signalling effect of all of the visual signalling equipment. Steady beacons are put to use in situations where only low-threshold signal pulses are required or an information signal needs to be emitted.
