Another new technology for intelligent lighting system?

Recently, researchers from the University of Cambridge in the United Kingdom used a combination of nanotechnology, color science, advanced computing methods, electronics and unique manufacturing processes to design a next-generation intelligent lighting system.

The researchers combined system-level color optimization, device-level optoelectronic simulation, and material-level parameter extraction. Specifically, the researchers engineered smart, color-controllable white light devices by using quantum dots, tiny semiconductors that measure just a few billionths of a meter across. Compared with the current standard LED, lighting based on quantum technology has higher light and shadow efficiency and better color saturation, and can achieve a lighting effect close to daylight.

The researchers generated a computational design framework from a color optimization algorithm for neural networks in machine learning, and developed a new method for modeling charge transport and light emission. The smart lighting system, called QD-LED, uses a variety of primary colors, beyond the commonly used red, green, and blue, to more accurately simulate white light. By selecting quantum dots of a specific size, that is, between 3 and 30 nanometers in diameter, the researchers were able to overcome some of the practical limitations of LEDs and achieve their desired emission wavelengths to test their predictions.

The research team also found that by using the three primary lighting colors conventional in LEDs, they were able to more accurately reproduce daylight. Early tests of the new design have shown excellent lighting performance, with a wider operating range and a wider custom spectrum of white light than current smart lighting technologies.

Professor Jong Min Kim from the Engineering Department of the University of Cambridge said: "This is a world first, a fully optimized intelligent white lighting system based on high-performance quantum dots. This means that intelligent white lighting technology based on quantum dot technology, It will become a new milestone in the field of modern lighting.
