More choices for energy-saving lighting

Philips, which is based in the Netherlands, has produced a strip of lighting made from OLEDs that can be powered directly from a mains electricity supply. That may not seem to be a brilliant invention, but in the lighting business it is a breakthrough. Although still at the laboratory stage, it will eventually mean that bulky power electronics and transformers will no longer have to be used with OLED lights, which brings down costs, simplifies design and allows them to be fitted into more products.
