Paper Abstract

An innovative way of modeling dual-phosphors-converted white mid-power LEDs is established and demonstrated. We use near-field chromatic luminance measurement data to select ray tracing modeling parameters in LightTools and propose some key parameters to predict characteristics of LEDs accurately. Based on our model, we can precisely predict the change in efficacy and in correlated colour temperature of embedding LEDs in optical materials.
