Abstract: A display element and a display device in which the display element is mounted. The display may be a variable message sign. The sign includes a tube-like housing in which lenses and apertures can be disposed. The light exiting a light source is emitted via an emitting surface, by way of which an illuminated traffic sign results from interacting with further display elements. The light source and the optical elements are disposed at different heights in the horizontally oriented housing. The optical axes can thereby extend horizontally, or the optical elements can lie on a main axis which is tilted downward in an radiation direction. In both cases, sunlight impinging from above at an angle advantageously falls on the LED to a slight degree, by way of which the phantom light phenomenon is minimized.

Abstract: In a method for the production of optical bands with several optical fibers, the surface of the optic fibers in said bands is treated such as to increase the optical damping in sections of the optic fibers. The generated damping may be reliably adjusted, whereby during (or after) the processing of the surfaces a measuring light is introduced into the fiber optic and the light output at the other end of the band is measured by means of a sensor such as a CCD camera. Possible production errors can thus be compensated for during the production process, for example, by an increased process time for the optic fiber. Optical sensor bands can be produced by the above method for application in the bumpers of motor vehicles as recognition sensors for the impact of a pedestrian. Other applications in which the bending of a sensor band is to be determined by optical means are also envisaged.
