Měření a optimalizace vlastností LED driveru pro automobilové aplikace

Abstract

This project is dealing with problems of managing circuits for power LED feeding. These circuits are being used for passenger cars front head lights. The function of widely used switching suppliers is described herein. The main task is to measure and compare effectiveness of given managing circuits and describe their function. Measuring is put together in for of protocol, where needed tabular forms and graphs are shown. In this project is also paid attention to power LED, on which required optical properties significant for car applications are measured. Main goals of this project are design and realization of managing circuit for power LED feeding. This managing circuit is equipped with special integrated circuit, that is directly designated for this function.
