ILLUMINATING SPOTLIGHT PROJECTOR AND LIGHTING INSTALLATION WITH OFFSET LIGHT SOURCE

摘要

The invention concerns an illuminating spotlight emitting a narrow beam comprising a highly concentrated light source and a concave reflector for emitting an illuminating beam in a specific direction, along an emitting axis (XX). Said spotlight comprises a converging lens interposed between the source and the reflector, and in a plane (P) passing through a conical segment (ab); the source (S) is bordered laterally on the reflector side with a sector of the converging lens (LA) providing a virtual image of the source (Sc) located beyond the emitting axis (XX), on the side opposite to that of the lens (LA); the virtual image (S') of the light source (S) being formed at the focus (F) of the conical segment (ab) locally defining the reflector (RF).
