Abstract (en)
[origin: WO2008081138A2] A power transmitter (T) transfers energy by optical route toward an electric device (DE), such as a mobile phone, comprising a battery (BI) linked to a photoreceptor (PR). The transmitter comprises: a detector (DP) for detecting a presence signal (Sp) emitted by the electric device so that the transmitter emits a low power light beam (LB), a positioning mechanism (PM) and an variable optical focalization system (OF) so as to position the low power light beam on the photoreceptor (PR), a circuit (CAR-SL) for controlling the reception power of the photoreceptor during battery charging by the photoreceptor, and a detector (DP) of end of charging of the battery to stop the emission of the light beam.
