The highly inefficient incandescent light bulb is now a thing of the past, banned from European supermarket shelves in favour of more efficient lighting. The ban is part of the EU’s strategy to reduce overall energy consumption and become more environmentally friendly.
Now, other types of lighting, such as the halogen lamp, are also coming under scrutiny. Much of today’s research into alternatives has focused on organic electroluminescence, a lighting solution that promises to surpass even compact fluorescent lamps (CFLs) in efficiency. Of particular interest are organic light-emitting diodes (OLEDs), in which a film of organic compounds emits light in response to an electric current. Read more.
