Problem
Obstacles such as wind turbines are required to display red warning lights at night, but continuous illumination disrupts nearby residents, wildlife, and the natural darkness of the night sky. Traditional lighting systems operate regardless of actual air traffic, leading to unnecessary energy consumption and light pollution.
Solution
Lanthan Safe Sky offers a demand‑controlled night‑lighting system that activates obstacle warning lights only when an aircraft is detected via its transponder signal. The ground‑based receiver monitors transponder emissions from aircraft at all altitudes without emitting radar, ensuring reliable detection while remaining safe and low‑cost. When no aircraft are nearby, the system keeps the red lights off, restoring darkness for communities and ecosystems. The solution is engineered in close cooperation with regulators and customers, providing a certified, easy‑to‑install compliance option for wind farms and other low‑altitude obstacles.
Target Audience
Primary customers are wind farm operators and owners of other low‑altitude aviation obstacles who must comply with night‑time lighting regulations while minimizing environmental impact.
Features
- Ground‑level transponder receiver that detects aircraft from take‑off to cruising altitudes without radar emissions
- Automatic control logic that switches obstacle warning lights on only within a configurable safety radius of detected aircraft
- Minimal illumination time reduces energy use and light pollution while meeting aviation safety standards
- Customizable transponder units tailored to specific projects and regulatory requirements
- Certified, regulator‑approved design enabling straightforward, cost‑effective compliance for wind turbine operators
