Maintenance-free emergency exit signs

Photoluminescent technology

Lufthansa Technik has developed and certified a new generation of exit signs. Based on the photoluminescent technology used in its popular GuideU floor path marking system, it offers many benefits: No power source required, unlimited lifetime, zero maintenance and friendliness to the environment. 

  • Exit Signs examples
    The photoluminescent exit signs only have to be installed once.
  • Exit Signs in cabin
    They replace the existing maintenance-intensive exit signs at the flexible curtains in the cabin.
  • Exit Signs - one example
    The signs are available in 30 languages and for all commercial aircraft types.
Multitype STC and unlimited lifetime

The new exit signs replace the existing maintenance-intensive exit signs with radioactive tritium technology at the flexible curtains in the cabin. Made from the self-illuminating, aging-resistant and completely maintenance-free GuideU material, the new signs simply have to be installed once. With a multitype STC (Supplemental Type Certificate), the new signs are available for all commercial aircraft in use today and are already installed ex-factory by Airbus.
