Abstract. The paper relates to a signage panel with LED edge lighting, capable of ensuring uniform luminescence on both sides of the visible surface. The structure of the panel is a sandwich type, consisting of PMMA plates, backlit foils and inscribed self-adhesive foil, all mounted in a thin aluminum frame. The lighting is achieved by a continuous LED strip, placed on the upper edge, and the uniformity of the light is obtained by transmitting it through the mass of the Plexiglas Edge Lighting material and by reflection from the aluminum metal foils applied to the sides. The product allows for low energy consumption, small thickness (10-15 mm), WiFi connectivity, and modular cascade assembly. It is intended for heavily trafficked interior spaces, offering a modern, reliable and aesthetic solution for signage and advertising. The research was carried out within the project “Innovation, Research and Construction of a Signal Production Factory” funded under the POR N-E Regional Program, Code MySMiS 338462.
Keywords: Signage panel, LED Chip on Board lighting, PMMA Edge Lighting.
