Making brighter and more efficient LEDs

Light-emitting diodes (LEDs) are everywhere in modern life, powering everything from smartphones to home lighting solutions. However, a significant drawback of current LEDs is that increasing their power to achieve greater brightness leads to decreased efficiency. A group of researchers from Nagoya University in Japan has discovered a method to enhance LED brightness while preserving their efficiency. Their findings could lower the costs and environmental effects associated with LED manufacturing while enhancing performance in areas such as visible light communication and virtual reality (VR) glasses.
