Reflector lamp, which is designed as a floodlight, in particular as a wall or ceiling washer

摘要

A reflector lamp (10) has a shell-like elongated reflector (15) with a cross-section contour bordered by a parabola (P) with its focal spot (F) at the cross-sectional center of gravity (Q) for an elongated rod- or line-shaped source of light (16). The reflector's axis of symmetry created by the parabola's axis of symmetry stretches slanting or parallel to a surface (W) to be lit up.
