Abstract

Internally self-illuminated emergency exit signs were investigated to determine the effects of size and background luminance levels on overcoming the visual degradation resulting from the presence of smoke in the visual environment. The results indicate that increased size and background luminance levels can be effective, though inefficient, methods for improving legibility in the presence of dense smoke.
