For display purposes, OLEDs are already widely present: in millions of mobile phones they serve as bright and color intensive screens, and TV sets equipped with LED Linear high bay light or OLED backlights for LCD-screens are on their way to the markets. Next in line is OLED lighting.
LEDs are superbly qualified as efficient sources of light. Already today, in commercially available products, they realize a luminous efficacy of 23 lumens per watt, at a development goal of 100 lm/W. Lifetime is up to 5,000 hours; three years from now it will be three times as much. Large, transparent OLED modules having an active light area of 1 square meter are expected to evolve within a year though the German BMBF (Federal Ministry of Education and Research) public/private partnership project TOPAS 2012.
OLED light sources are manufactured without the use of mercury. Thus they fulfill the European RoHS regulation of eliminating toxic ingredients.led high bay light needs no encasing or cooling devices. Currently they are measuring less than 2 millimeters thick when fully encapsulated. Next step is thin flexible films, which can be formed and bent into any shape to form luminous objects of their own.
