Locating emergency exits under conditions where visibility is affected by fire, smoke or turbid water is often extremely difficult. According to Oxley Avionics, this problem has now been overcome with the introduction of its Survivolite emergency lighting system. This product reportedly utilises high-intensity LEDs designed to emit light at a wavelength matching the response of the human eye.
Developed originally to meet the requirements of military helicopters for an efficient, lightweight and easily installed emergency exit illumination system,it is also believed to be ideal for illuminating gangways and exit doors in passenger aircraft, ships, offshore rigs and accommodation platforms and public buildings.
Survivolite contains high-intensity LEDs, each producing a light output with a dominant wavelength of 525nm, ensuring optimum visibility of the emitted light. Light output is typically 35 cd/m and the operating temperature range is-40°C to 70°C.
Survivolite can be supplied in discrete light module form or can be constructed from continuous strips of extruded translucent silicone rubber. The system is stated to be fire resistant and waterproof and meets stringent military environmental requirements. Trials are reported to have proved high-density LEDs to be far superior to any other technology for visual penetration of smoke and turbid water.
The same LEDs can also be mounted in custom-designed Survivolite emergency signs that can be used to display illuminated arrows, lettering or pictograms indicating exit routes and escape points.
