摘要

For the precise light behavior controlling in precise LED product design, the rapid and accurate LED model is need to build. The optical model of low and high power LEDs were built up and simulated by using Monte Carlo ray tracing, and were verified by the light intensity patterns in different midfield distances with the normalized cross correlation (NCC) algorithm. The one-dimensional intensity patterns were tested with a simple experimental set-up. The accuracy is higher than 99.55% in midfield and far-field region for NCC between the simulated light pattern and experimental measurement. The rapid optical model design assistant with NCC can be applied in varied precise LED illumination product design in midfield and far-field.
