Ormocer-based lighting eliminates peripheral colour effects
Abstract:
At nano tech 2010 in Tokyo, Fraunhofer researchers will present some remarkable nanotechnology developments: pin-sharp projections, light that is 'whiter than white' and varnishes that emit sounds in response to temperature changes.
Dr Michael Popall of the Fraunhofer Institute for Silicate Research ISC in Wurzburg, Germany, says: "For a long time, producing white light with no peripheral colour effects was an almost unsolvable technical problem. White light is produced by mixing the complementary colours red, green and blue. Undesirable refraction occurs with conventional beamer technology, resulting in coloured streaks on the periphery of the projection." However, his team has developed a light diode, smaller than a pinhead, that transmits light through thousands of lens structures measuring only a few hundred nanometres in diameter.
Popall adds: "The tiniest of red, blue and green light diodes on the most condensed space produce the light, which is then bundled and homogenised by the nano-structured Ormocer optics.
