Kaiserslautern Central Station — Modern platform lighting system

Kaiserslautern Central Station is one of the region's most important transport hubs, connecting thousands of local and long-distance passengers daily. The extensive platform areas place high demands on safety, wayfinding, and lighting quality. As part of the platform lighting modernization project, the system was converted to DB platform lights from FLASHAARin 2024.

In February 2024, a total of 400 existing light fixtures at Kaiserslautern Central Station were replaced. The previously used systems with TCL36W lamps had elongated opening dimensions, which were adapted to a modern and future-proof size using specially manufactured adapter frames. This allowed the new lighting technology to be integrated efficiently without extensive structural modifications to the platform roofs.

The FLASHAAR DB platform lights used were originally developed specifically for the characteristic GMP platform roof, but can be flexibly adapted to a wide variety of roof and ceiling situations. The opening dimensions, recessed or surface-mounted installation, number of light heads, and light distribution curve can all be individually tailored to the specific environment. In addition, adapter frames and recessed and surface-mounted frames are available to optimally implement even challenging existing installations.

A particular focus of this project was on the lighting quality. Each light head has 16 LEDs in combination with special lenses behind a ceramic-printed glass. This results in precise light control with optimal illumination of the platform while simultaneously providing excellent glare control for passengers and train drivers.

Besides lighting quality, operational reliability was a primary focus during development. Each light head has four parallel circuits. Even in the theoretical event of a single circuit failure, the luminous flux remains almost entirely constant. Furthermore, each light head has its own electronic control gear. Should one of these devices fail, the luminaire continues to operate, albeit with reduced luminous flux. This safety concept is complemented by integrated surge protection and thermally broken housing sections.

The project also sets standards in terms of energy efficiency. Despite the large number of installed lights, the total electrical load is only 7,600 watts. Each light requires only 19 watts of power. With 400 lights installed, this is roughly equivalent to the power consumption of just 1.5 standard washing machines. This reduces operating costs and simultaneously supports sustainable energy goals.

The installation in Kaiserslautern is part of a supra-regional lighting concept. Similar FLASHAAR platform lights are already in use at other train stations, including Freiburg, Mainz, Saarlouis, and Merzig. The modular and repair-friendly design ensures low maintenance costs and long-term reliability. The modernization of the platform lighting at Kaiserslautern Central Station has created a durable, energy-efficient, and technologically advanced lighting solution that optimally combines safety, cost-effectiveness, and light quality.
