Classification: CPC H  G | IPC G  H

Claim 19:
20. A wireless optical charging system, comprising:
a transmitter which transmits a wireless optical charging light source (optical source) beam as light with an energy increased by resonance; and
a receiving unit which receives light transmitted from the transmitter and converts an energy for some light among the received light into an electric energy to charge devices,
wherein the energy of light increases due to the resonance that occurs between the transmitter and the receiving unit due to the light reflected from the receiving unit to the transmitter,
wherein the transmitter includes:
a light source unit;
a light transfer mirror which transmits light received from the light source unit to the receiving unit; and
a collimator which is disposed between the light source unit and the light transfer mirror to convert light output from the light source unit into a collimated ray.
