The LED-based optical wireless power transmission (OWPT) system is a novel approach of remote power transmission technology, and it has virous merits such as long transmission distance. However, the output power of OWPT system with single LED is difficult to raise due to current manufacturing technology. Therefore, arraying multiple LEDs as LED array is the effective way to enhance the total output of the LED-based OWPT system. In this paper, the experiment data of the LED-array OWPT system is discussed. As a result, around 400 mW output power was obtained at 1 m tranmission distance by LED-array OWPT system.
