Abstract

A wireless optical charging system according to the present invention comprises: a transmission unit that transmits a laser beam as light that has had the energy thereof increased through resonance; and a receiving unit that receives the light transmitted from the transmission unit and converts the energy of some of the received light into electrical energy to charge a device. As such, the present invention has the effect of resolving the issues of harmfulness to the human body and distance limitation by using resonant laser power transmission technology.

Description

technical field [0001] The present invention relates to a wireless optical charging system and its charging method. More specifically, it relates to the following wireless optical charging system and its charging method: if the wavelength of the light source beam in space is divided, and the two-dimensional light is randomly arranged as the receiving part If the retro-reflector is used, only the wavelengths with the same optical path resonate and can transmit optical power. Background technique [0002] As most of the current commercial wireless charging technologies, the magnetic induction method is a short-distance charging method that needs to be in close contact with the charger within 1cm to charge. In order to compensate for this method, the magnetic resonance method proposed uses the resonance frequency. The magnetism transmits to the same frequency, so it can be charged even if it is not close, and has the advantage of not interfering with charging even if there are ...
