High Efficiency Light Source for Distributive Lighting Systems (DLS) 2001-01-0451

DLS offers exciting new possibilities for design and performance of headlamps. The powerful HID source technology is ideally suited to serve as light source for such a DLS, combining the benefits of both technologies to a completely new headlighting concept.

The intention of the paper is to give an impression of the efficiency and performance of the system and to point out the prerequisites and parameters for the light source that influence the performance.

Starting from the performance of present HID headlamps and based on sound considerations of losses of the various components of a DLS, the beam requirements are traced back to the necessary properties of a HID light source and bulb driver dedicated for DLS.

From both calculations and measurements an estimation of the overall performance for the system is derived, with focus on incoupling efficiency.
