LED Emergency Exit Signs

Conventional Exit Signs are expensive to run

Conventional (fluorescent) Emergency Exit Signs are a major "hidden" cost factor in most buildings:

• Fluorescent tubes need regular replacement before (!) they fail: Labour & parts costs
• Batteries (usually NiCd) need replacement every 4 years: Labour & parts costs
  
• Batteries require annual maintenance (deep discharge)
• Ongoing energy costs (8W tube + ballast, 24 hours, 365 days).

In comparison to these costs the initial purchasing price quickly becomes insignificant.

The innovation: Zero maintenance over lifetime!

The HELIOS LED Exit signs have been designed to completely eliminate any maintenance cost over a lifetime of 10 years  in 24 hour operation.

The key to this achievement is an innovative conduction of the light inside the sign. This technique makes it possible to use only one premium 1W LED to light the entire sign (standard size 120x250mm). This results in a standard viewing distance of 24m. The batteries that keep the sign lit during an emergency should of course provide a similar lifecycle as the LEDs (i.e. no replacement and no maintenance over lifetime). This is the case with the batteries used in the HELIOS range.

What is different to other LED signs?

Using only one LED opens the door for a new way of mounting the light source. In this manner, the LED experiences very low temperatures and this in turns is a guarantee for an extremely high lifetime because it reduces the fading to an extremely low level.

In contrast, LED signs with 10, 12 or more single LEDs usually fade to 50% or so of the inital light output after one year of operation.
