ABSTRACT:
A device which can be used on rotating visible surfaces of, for example, machines, appurtenances, vehicles, and fans, utilizes N light sources, evenly disposed on a flexible substrate, and connected by means of a driver to a microcontroller with an independent power supply. A synchronization sensor is connected to the microcontroller. The light sources may be LEDs—one- or three-colored (RGB). The synchronization sensor responds to gravity when mounted on a rotating surface, whose rotation axis is not perpendicular to the Earth's surface, or is actuated at a position relative to a given immovable point, provided the rotation axis is perpendicular to the Earth's surface. A light sensor is connected to the microcontroller, which in turn is connected to a control panel. Sensors and the control panel are disposed on the substrate. The microcontroller has a serial interface.
