electronic tile implements variable colour and/or brightness and/or temperature. This tile is inserted in a system of several identical tiles which covers a surface. A special tile controls the system parameters such as colour, brightness, temperature, thus colouring and conditioning the surface and/or the environment at will. Every single tile and each sub-part of it can be indipendently controlled. The tile implements the above mentioned functionalities without any wiring. At least one tile has to be connected to the electrical supply.
