Enhancing LED modeling accuracy to extract practical parameters and compare simulation

Abstract

This paper presents a comprehensive analysis of parameters required for accurate modeling of Light-Emitting Diodes (LEDs) and their subsequent use in simulator software for comparing practical and simulation results. The focus of the study is on parameter extraction from the LED model, including key variables such as LED capacitance value, saturation current, emission coefficient, shunt resistance, and series resistance. The research showcases a practical methodology for parameter extraction that yields results closely aligned with simulation outcomes when the extracted parameters are incorporated into the simulation framework. This study is better than previous studies from the point of extracting the five parameters for LED modeling through the use of several experiments which their practical results has been verified by implement simulation approaches.
