要約(英語): For Internet-of-things (IoT) terminals, wiring or battery replacement are not effective power supplying methods due to excess installation and maintenance cost. Optical wireless power transmission (OWPT) is a promising candidate for easy charging with the advantages of long transmission distances, good directionality, and portable size. In this research, a light emitting diode (LED) based OWPT system that achieved safety light beam, portable size, and large electricity power supply was designed and demonstrated through simulations and experiments. In addition, a novel design of the LED-array OWPT system, which has arrayed multiple LEDs as the entire light source, has been proposed to improve the final output above 380 mW. In particular, the tolerant distances and alignment deviations of both single-LED and LED-array OWPT systems were analyzed in detail.
