Document Type and Number:
Japanese Patent JP2023170776
Kind Code:
A
Abstract:
To provide a power receiving device, a power feeding device, an optical power feeding system, a power receiving method, a power feeding method, and an optical power feeding method capable of simultaneously transmitting power and information via power feeding light.SOLUTION: While power transmission is performed by sending out power feeding light in which information is inserted by wavelength modulation, the power feeding light is received by a light receiving unit having different sensitivity according to a wavelength, power reception is performed by converting the power feeding light into electric power, and information is extracted based on a magnitude of the electric power that changes according to change in a wavelength of the power feeding light.SELECTED DRAWING: Figure 7
