An emergency exit sign should be invisible to the architect, but clearly visible in an emergency, says Harald, describing the balancing act EOOS had to master when designing Puresign. Only 28 millimeters (barely over an inch) deep, the result is an extremely flat emergency sign, the first to be equipped with a micro LED spotlight along its underside,
a pioneering design in its category. In an emergency, the micro LED lights the escape route – and it can do so for more than 50,000 hours. All the electronic components are hidden away inside the aluminum frame, so that interior designers deploying the emergency sign certainly have no reason to be critical of its esthetic qualities.
