| description | A method for wireless power transmission in a system comprising a power transmitter which in turn comprises a first light source and means for directing the light emitted by the first light source to a desired direction, and at least one power receiver comprising a first photo-detector for receiving the emitted light and for converting it into electric current. A second light source included in the power transmitter is used for transmitting light around the light emitted by the first light source and substantially parallel to it, the intensity of the light being lower than that of the light emitted by the first light source. A second photo-detector included in the power receiver is used for detecting the light emitted by the second light source and for transmitting a control signal to the power transmitter in response to a successful reception of the light emitted by the second light source. The first light source of the power transmitter is switched on in response to the reception of the control signal from the power receiver informing of the reception of the light emitted by the second light source. |
