LEDs no longer are just light bulbs. They’re now starting to appear as a built-in feature for ceilings – an advance predicted 50 years ago by science fiction writer Isaac Asimov. These tiny light-emitting diodes, often touted as the ultra-efficient replacement for old-fashioned incandescents, are being integrated into clothes, carpets and ceilings the same way that some solar panels have been tucked into rooftop shingles. The OneSpace luminous ceiling, by lighting company Philips, makes its debut at the Light + Building trade fair in Frankfurt, Germany. It uses LEDs packed tightly in a mesh, combined with textile, to create an ultra-thin, sound-absorbing panel that offers homogeneous light with no exterior fixtures.
