Tracing The Light Inside An LED

The performance of white LEDs can be improved, based on better knowledge of the absorption and scattering of light inside the LED. A new method, developed by the University of Twente in The Netherlands and Philips Lighting, can lead to efficiency improvement and powerful design tools.

White LEDs can be made even more efficient and powerful, researchers of the University of Twente and Philips Lighting now prove. They found a detailed way to describe the light that stays inside the LED by absorption and scattering. This is very valuable information for the design process.
