Researchers have designed smart, colour-controllable whitelight devices from quantum dots – tiny semiconductors just a few billionths of a metre in size – which are more efficient and have better colour saturation than standard LEDs, and can dynamically reproduce daylight conditions in a single light.
The researchers, from the University of Cambridge, designed the next-generation smart lighting system using a combination of nanotechnology, colour science, advanced computational methods, electronics and a unique fabrication process.
The team found that by using more than the three primary lighting colours used in typical LEDs, they were able to reproduce daylight more accu...
