Abstract
An earth positioning system (EPS) is provided. The EPS includes a plurality of fixed LED lights with communication functions and a mobile communications device. A cloud computer and at least one map marked with world coordinates of the fixed LED lights may be further included. The LED light includes a substrate, at least one LED die, a power supply, a wireless communication module, a control unit and a housing. The LED lights may be arranged in indoor and outdoor environments, with coordinates represented in longitude, latitude and altitude. The coordinates are included in a map data of the cloud computer. When the mobile communication device moves with its carrier, the world coordinates of the mobile communication device can be located based on the coordinates of the LED lights nearby or based on the unique IDs of the LED lights together with the aforementioned map.
