Abstract
A light bar includes an arrangement of several light elements reciprocally spaced behind one another in the longitudinal bar direction where each light element produces a light beam, a reflection surface formed on a light-impermeable reflector body and producing a diffuse scattering effect where a first portion of the light beam of each light element is directed at the reflection surface, a light-permeable window element at which light produced by the light elements exits the light bar. A second portion of the light beam that is different from the first portion is directed past the reflection surface onto the light exit window. The light radiated by the light bar is composed of a direct light proportion and a scattered light proportion, the relative ratio of which in a suitable configuration of the reflector body and the window element can be different in different radiation directions of the light bar.
