Title:
WIRELESS POWER TRANSMISSION DEVICE AND LIGHTING APPARATUS USING SAME
Document Type and Number:
WIPO Patent Application WO/2015/099272
Kind Code:
A1
Abstract:
The present invention relates to a wireless power transmission device comprising: a pair of transmitting electrodes; a pair of receiving electrodes provided to be spaced so as to correspond to the transmitting electrodes; and link capacitors respectively formed between the transmitting electrode and the receiving electrode, and wirelessly transmits energy from the transmitting electrodes to the receiving electrodes by means of a face-to-face transmission method by using an electric field formed around the link capacitor, thereby providing remarkable effects in comparison with a conventional inductive magnetic coupling method. In addition, since the transmitting electrode is formed to be larger than the receiving electrode and energy is transmitted to only the part at which the transmitting electrode and the receiving electrode overlap each other, the present invention ensures a certain degree offreedom in the position of the receiving electrode, and thus, when a lighting lamp is formed together at the receiving electrode, the lighting lamp can be moved to a suitable position without a cumbersome wiring operation.
