Analysis Characteristic XPG LED Using Microcontroller Circuit Simulation

Abstract

This work is concerned the detailed calculation of internal circuit of XPG LED and the characteristics with designing the control circuit to calculation the different brightness between XPG LED and types with lens LED diode and the point light of LED diode. The control is used method of digital circuit by increasing the duty cycle of PWM supplying voltage used the microcontroller with software development written in micro-basic language (program XPG circuit simulation) and hardware to measuring the intensity of brightness, which emitted from the LED. Using the photo resistance and this parameter read it by the microcontroller to be display it on screen. This result gives the best characteristics of XPG LED for suitable lighting.
