Abstract:
1. A device for visualization of information on a rotating visible surface comprising light sources including a plurality of light emitting diodes, evenly disposed in an array on a substrate and connected by means of a driver to a microcontroller having an independent power supply and mounted on the substrate, and a synchronization sensor connected to the microcontroller, the LEDs being of one or various colors, wherein the LEDs ( 1 ) are RGB, the substrate ( 2 ) is flexible, and the synchronization sensor ( 6 ) responds to gravity when mounted on a rotating surface, whose rotation axis is not perpendicular to the Earth's surface or if the rotation axis is perpendicular to the Earth's surface, the synchronization sensor is actuated at a position relative to a given immovable point, and wherein a light sensor ( 7 ) is connected to the microcontroller ( 4 ), which in turn is connected to a control panel ( 8 ), the two sensors ( 6 and 7 ) and the controlling panel ( 8 ) are disposed on the substrate ( 2 ) and the microcontroller ( 4 ) has a serial interface ( 9 ).
