Public signaling for system distributing energy, a fluid or data, comprises array of luminescent diodes at distribution points which may be controlled from local or remote station to inform public

摘要

For a system (4,5) making electrical energy available at various points (1,2,3) of a public place, arrays of luminescent diodes (6) are installed at the distribution points. The arrays are controlled from a local station (8) or more remotely (11) and may be directed to indicate the type of product available, whether it is available at a particular time or a route to follow. The diodes may be fed (10) from the distribution points or independently.
