Raumsparender Infrarot-Scheinwerfer für Fahrzeuge nach dem Projektionsprinzip

摘要

The headlamp has between the reflector (100) and the lens (200) a filter (300) that is opaque to visible light and transparent to infra-red light. The filter is displaced between a position where it is clear of the visible light beam from the light source (110) and a position where most of the beam passes through the filter.
