Display unit and light box therefor

摘要

A display unit is formed of a number of individual light boxes which are electrically and mechanically interconnected in one or more rows. Each light box comprises complementary mounting and hook-on strips at two opposite sides for detachable interconnection of the light boxes in juxtaposed rows. Complementary electric connecting means are each arranged at one end of each light box for electrically and mechanically interconnecting light boxes in the same row. Current is supplied to the light boxes from one end of each row of light boxes by means of a conductor rail. To provide a play of lights, the lamp fitting of each light box has a control circuit which is designed as a receiver and whose turning on and off of the lamp fitting is controlled by a transmitter in the power supply circuit of the display unit.
