ABSTRACT:
A luminous band display device is shown for the thermometer scale-like diay of the position of a control, e.g., of a turning knob or slide, having a series of luminous segments arranged in a circular or straight pattern. The luminous segments are formed by the ends of light guides which are led out from a generally cylindrical luminous center in a star-shaped or similar pattern. The luminous center consists of a cylindrical socket receiving a light source, and a cover which carries at least one color band and which can be rotated relative to the socket by means of the control is located between the light source and the beginning of the light guide. The light guides are arranged over approximately three fourths of the circumference of the luminous center. In order for all luminous segments of the entire display scale to light in only one color even in the stop positions of the control, an outlet opening and a guide for the color bands projecting from the socket are provided.
