Scientists introduce a radically new design principle that is based on an analytical model instead of a numerical approach. The model predicts a white LED's color point for any combination of design parameters and allows for a much faster design, by up to a 1 000 000 times, resulting in reduced design and production costs.... nanowerk · 1 week
