Alphabet of light is a language of light to communicate freely, it is an elementary principle that generates an open system. Starting from an abacus of essential geometric elements, BIG designs a tool for modeling spaces. These simple basic modules, with precise geometric proportions, can be combined with each other to build infinite structures of light, essential or more complex. The idea of BIG is combined with Artemide's optoelectronic expertise to define an innovative construction principle and return a continuous and comfortable light. It is a minimal presence that contains a very high patented innovation. The luminous intensity of the lamp is adjusted via the Artemide APP.
