This paper presents the mathematical and lighting models of the FF (Free Form) ellipsoidal projector with an MPXL discharge light source. The use of models based on “elementary reflection” has been suggested for lighting calculations. The light intensity in the specific direction of projector's space has been determined by the “reverse ray test”, which makes possible determination of the shape of the “Figure of The Bright Points” and luminance distribution inside the figure. The procedures presented below facilitate development of computer programs for projector modelling and calculations.

The problem of reduction of power consumption by car lighting devices is a constant subject of interest of vehicles designers. The limited power balance in vehicles, as a result of introduction of the bigger and bigger receiver sets of energy number, indicates the continuation of researches in order to improve the power efficiency of devices. The goal of presented problem in article it to create the CAD tools, enabling computer calculations of optical and light car projectors systems with extended light efficiency. Presented theoretical system model along with the study of light calculations method allowed to expand the possibility of uses of projectors with better power and light parameters comparing to conventional systems.
