THE NEW FILM INTELLIGENT ELECTRONIC CONVERTERS USING NEW DUPONT AND ESL HIGH TECHNOLOGY MATERIALS FOR LOW POWER DISCHARGE LAMPS

摘要

High pressure light sources: metal halide lamps and sodium discharge lamps are nowadays commonly used for the illumination of roads, streets, stadiums and rooms. They have a high coefficient of colours turn-over, high light efficiency and long service life. One of the methods of increase operational reliability, and service life of discharge lamps is applications full electronics stabilized-ignition circuit supply from main, instead classical inductive ballast and starter. This circuit is an electronic converter (ballast). Contemporary stabilized-ignition circuits are generally electronic ones, and increasingly, they are built using thick-film technologies. This paper examines the results of research work carried out at the Technical University of Cracow, in collaboration with the Private Institute of Electronic Engineering, Technical School of Communications and the Cracow Electronic Works. The research work was focused on the development of new hybrid microelectronic thick-film converters for discharge lamps. The article also discusses electronic circuits that utilize high technology materials and hybrid modules technologies as well as the application of specific integrated circuits (ASIC's). It was the thick film technologies and surface mount technology that were used to build the microelectronic converters. Mention is also made of advanced technologies for assembling and packaging. Finally, the development prospects of hybrid circuits are outlined.
