A team of researchers from the University of Cambridge have designed a next-generation intelligent lighting system using a combination of nanotechnology, color science, advanced computational methods, electronics and a unique manufacturing process.. This new LED bulb is more efficient and has better color saturation than standard LEDs, and can dynamically reproduce daylight conditions in a single light.

The team found that by using more than the three primary lighting colors used in regular LEDs, they were able to reproduce daylight more accurately. Preliminary tests of the new design show excellent color rendering, a wider operating range than current smart lighting technologies, and more Extensive white light customization.

Smart lighting can also respond to circadian rhythms, which regulate the daily sleep-wake cycle, so light is reddish-white in the morning and evening, and bluish-white during the day, they explained. Natural Communication.

So, when a room has sufficient natural or artificial light, good glare control and outside views, it is said to have good level of visual comfort. Since the color of objects is determined by lighting, intelligent white lighting must be able to accurately express the colors of surrounding objects, and they have achieved this by simultaneously using three different colors of light.

Cambridge researchers developed an architecture for a quantum point light-emitting diode (QD-LED) based on next-generation smart white lighting. They incorporate system-level color optimization, device-level optoelectronic simulation, and material-level parameter extraction. The QD-LED system uses several primary colors, beyond the usual red, green, and blue, to more accurately mimic white light.
