The ALVA series offers a variety of sizes, luminaire diameters and light emission angles – and a wealth of flexibility in terms of control. A range of separate ESYLUX outdoor motion detectors provide an alternative for demand-driven control of the bollard lights without integrated motion detectors.
ALVA bollard lights with integrated DALI motion detectors, built-in DALI bus voltage supply and intelligent networking in broadcast mode.
With the DALI actuator from ESYLUX (1), devices without a DALI interface can be easily integrated and then controlled based on motion and daylight levels.
The outdoor motion detectors in the RC, DEFENSOR and MD-W series offer a classic alternative for demand-driven switching of lighting groups in outdoor areas.
They are available in different versions, offer practical additional functions and provide impressively high-quality sensor technology.
In addition to the automatic switching on and off, the optional integrated DALI motion detector provides the ALVA series with additional, useful control functions.
For example, an orientation light that continues to emit a soft glow when there is no longer anyone in the immediate vicinity.
Alternatively, a temporary afterglow can be set, starting after the switch-off delay time following the last detected movement.
Another option is the twilight switch function. Once activated, the luminaire switches on as darkness falls, independent of motion detection, and switches off automatically the following morning.
The die-cast aluminium housing and extruded profile deliver protection from sea air and ensure maximum durability, with optimal protection against the ingress of water and dust. The powder-coated surface looks elegant, is dirt-resistant and is easy to clean thanks to its high level of resistance to cleaning agents (anti-graffiti effect).
To ensure that the technology inside the housing is also optimally protected against environmental influences, the junction box and driver box are installed at a safe height above the base plate of the bollard lights. This ensures that the electrical components remain dry and undamaged, even in the event of water penetrating the bottom of the housing due to heavy rainfall.
The increasing levels of light during the night, otherwise known as light pollution, causes damage to a variety of organisms. Here are a few examples:
Light attracts millions of insects, who circle around the light endlessly, often driving them to exhaustion and death. Birds can fatally collide with buildings that are illuminated. Lighting also impacts the ability of trees to detect the current season and impairs their energy management. It makes it difficult for fireflies to find a partner and therefore threatens their existence.
The best light for nature is no artificial light at all. Light should only be used when it is really needed. Here are the most important points:
Switching on lights only when needed
Reducing light intensity to a minimum
No beams of light directed upwards
High degree of protection (prevents insects from entering and dying in the luminaires)
Only installing as much lighting as is needed
Lighting that tends to have a lower blue light content
More important than the light colour: switching off or dimming!
