Analyses of Bifunctional Systems 2001-01-0852

This article deals with the analysis of the opto-mechanical concepts of HID headlamps, which serve for the change of the light distribution to achieve both the low beam and high beam functions. This article describes the mechanical solutions for changing of these functions for parabolic systems, projector systems and projector-parabolic systems. Each of these systems uses the movements of the optical components such as the shield in projector and projector-parabolic systems and likewise the movement of the optical refractor, HID source or the reflector itself in the parabolic system. The goal of this article is to analyze the solution from the optical and mechanical point of view and the analysis of the advantages of each system.
