Abstract
A modular system for illuminated signs, in particular for road signs, includes a plurality of bars that can be put together so as to form a frame structure. Each bar has a full body made of a material usable as light-guide, for example polycarbonate, substantially transparent to the color of the light that propagates inside it, in which a LED light source is integrated. The system moreover comprises a plurality of modules in the form of letters, figures or symbols, which can be positioned within the aforesaid frame and are each also constituted by a body of material usable as light-guide, for example polycarbonate, substantially transparent to the color of the light that propagates inside it, with at least one LED light source integrated within each module. Each of the aforesaid modules is provided with at least one pair of terminals for connection of the respective LED source with a source of electrical supply.
