Application and advantages of all lighting functions for Beacons and Stake Lights

Light effects play a central role in signalling technology by providing clear visual signals to ensure safety and effectiveness. Below you will find an overview of the different types of light effects and their specific areas of application.

Reliable signalling without interruptions

Permanent light

Permanent light is an indispensable element in many safety-critical applications. It ensures a constant visual presence and is ideal for situations that require a permanent warning or status indication. Permanent lights are often used to continuously indicate a certain status or to signal a specific task. This light effect offers a reliable solution for permanent visual signals in signalling applications.

Regular light pulses for sustained signals

Blinking light

Blinking lights are characterised by recurring light signals that continuously blink to draw attention to a specific situation. This type of light effect is particularly suitable for applications where a permanent but not too intrusive visual warning or display is required. Blinking lights are often used to indicate hazards or conditions that persist for a longer period of time but do not require an immediate response.

Intense light flashes for acute warnings

Flashing light

Flashing lights produce short, strong light flashes that have been specially developed to attract maximum attention at critical moments. They are typically used in emergency situations or in the event of immediate danger, as the sudden brightness of the light flashes immediately attracts the attention of the viewer. Flashing lights are ideal for use as urgent warnings or emergency signals.

Innovative signalling with stochastic flickering light

EVS light

The Enhanced Visibility System (EVS) light utilises stochastic flickering light technology to create a particularly high level of perception. Developed on the basis of neurobiological principles, this light ensures a continuously high level of visual attention. EVS lights are an advanced solution for applications where a particularly conspicuous visual warning is required.

Combination of permanent light and blinking light

TwinLIGHT

TwinLIGHT combines the functions of permanent light and blinking light in a single signalling technology element. Users can flexibly switch between the two modes, which makes TwinLIGHT particularly versatile. This technology is suitable for applications that require both continuous signalling and a recurring visual warning.

Combination of flashing light and EVS light

TwinFLASH

TwinFLASH combines two powerful lighting functions: flashing light and EVS light. This solution makes it possible to switch between intense flashes of light for acute warnings and stochastic flickering light for sustained high visual awareness, depending on requirements. TwinFLASH offers a flexible signalling solution for various applications that require both immediate and continuous attention.

360-degree signalling for maximum visibility

Rotating light

Rotating beacons offer 360-degree signalling that ensures improved visibility from all directions. The all-round light effect is created either by the mechanical rotation of e.g. a rotating mirror or Fresnel lens around a light source or the electrical rotation of lighting elements, e.g. LEDs. Omnidirectional lights are ideal for environments where all-round coverage is required and ensure that the signal is clearly visible from any angle.

Other functions and features relating to light effects

Flexible adaptation to different requirements

Multicolour

In signalling technology, multicolour elements are used when a single signal element can reproduce several colours. These elements offer remarkable versatility, as they are able to produce different colours such as red, yellow, green and blue from a single light source. This adaptability makes this light effect particularly useful for responding to changing situations and different requirements. Whether for indicating status changes or as a warning signal - multicolour signal elements are an effective solution for flexible visual signalling.

Full coverage without blind spots

OmniVIEW

The OmniVIEW calotte ensures that there are no more blind spots thanks to its 360-degree dispersion. This solution offers complete coverage and optimised visibility, making it an ideal choice for comprehensive signalling requirements.

Up to 20 times brighter light for special applications

Ultrabright

Thanks to its sophisticated control, the innovative Ultrabright LED element shines up to 20 times brighter than conventional LED lights, making it the brightest permanent light the signalling industry currently has to offer. The intelligent electronics always get the maximum brightness out of the LED, depending on the ambient and operating temperature. The ultrabright element is particularly suitable for areas of application that place even higher demands on the visibility of visual signalling.
