Software predicts performance of phosphor down-converted white LED designs
Predictive modeling benefits from sophisticated algorithms and accurately measured data inputs, writes Chao-Hsi Tsao, Edward Freniere and Linda Smith.
In the last decade, accurate and predictive opto-mechanical software modeling has enabled adherence to performance, consistency, cost and aesthetic criteria without the cost and time associated with iterative hardware prototyping. More sophisticated models that include simulation of optical phenomenon, such as luminescence, promise to yield designs that are more predictive — giving design engineers and materials scientists more control over the design process to quickly reach optimum performance, manufacturability and cost criteria.
