High Power LED Parametric Modelling Using a Double Polynomial Approximation

Popis výsledku v původním jazyce

The topic of this paper is a building process of a real power LED mathematical model, based on the double polynomial approximation, focused on the 2-D load parametric characteristics. The model's input is the values of load temperature and electric current (independent variables), whereas the output is the value of standardized illumonance. The coordinates of the operating point are determined analytically, using the double polynomial (both transverse and longitudinal). The resulting 3-D model is then implemented in the MATLAB (text source code) and Simulink (block model) system environments and the Space compatible circuit model, as well. The core of the model is a system of optimal polynomial approximation functions. The mathematical principle of the method and a numerical example are then presented. The main idea of the paper is to offer an accurate power LED models for more extensive computer experiments and to verify the presented original approximation methods.
