Document Type and Number:
WIPO Patent Application WO/2012/169047
Kind Code:
A1
Abstract:
A non-contact power supply system (10) comprises a power-transmitting device (200) that includes a power-transmitting unit (220), and a power-receiving device that includes a power-receiving unit (110), wherein power is supplied in a non-contact manner from the power-transmitting unit (220) to the power-receiving unit (110) by means of electromagnetic resonance between the power-transmitting unit (220) and the power-receiving unit (110). The power-receiving device includes: an accumulator (190) for accumulating power received by the power-receiving unit (110); and a light-emitting unit (172) that emits light by receiving power that is received by the power-receiving unit (110), the brightness of the light changing in accordance with the power received. The power received by the power-receiving unit (110) changes in accordance with the amount of positional displacement between the power-transmitting unit (220) and the power-receiving unit (110). The user identifies the amount of positional displacement between the power-transmitting unit (220) and the power-receiving unit (110) by means of information that is provided from an interface unit (165) and relates to the brightness of the light-emitting unit (172).
