Power transmitting apparatus
A power transmitting apparatus ( 1 ) is provided with: a power feeder ( 13, 14, 15 ); a power receiver ( 23 ) disposed with a space from the power feeder; a power storing device ( 26 ) electrically connected to the power feeder and configured to supply power to a load ( 27 ); a distance changing device ( 16 ) configured to change a distance between the power feeder and the power receiver; a detecting device ( 25 ) configured to detect a power storage state associated with the power storing device; and a controlling device ( 11 ) configured to control the power feeder to change output power according to the detected power storage state, and configured to control the distance changing device to change the distance.
1. A power transmitting apparatus comprising:
a power feeder;
a power receiver disposed with a space from said power feeder;
a power storing device electrically connected to said power feeder and configured to supply power to a load;
a detecting device configured to detect a power storage state associated with said power storing device;
a distance changing device configured to change a distance between said power feeder and said power receiver; and
a controlling device configured to control said power feeder to change output power outputted from said power feeder according to the detected power storage state, and to control said distance changing device to change the distance according to the output power.
2. The power transmitting apparatus according to claim 1 , wherein said controlling device controls said distance changing device to reduce the distance if said controlling device controls said power feeder to increase the output power, and controls said distance changing device to extend the distance if said controlling device controls said power feeder to decrease the output power.
3. The power transmitting apparatus according to claim 2 , wherein
the load is a lighting apparatus, and
said power transmitting apparatus further comprises a supporting device configured to hang and support the load, said power receiver, and said power storing device as a whole.
4. The power transmitting apparatus according to claim 3 , wherein
said power transmitting apparatus further comprises a driving device configured to change a position of said power feeder,
said controlling device controls said driving device to move said power feeder to a position where said power feeder is opposite to said power receiver if charging said power storing device is required on the basis of the detected power storage state, and controls said driving device to move said power feeder to a position where said power feeder is not opposite to said power receiver if charging said power storing device is not required on the basis of the detected power storage state.
5. The power transmitting apparatus according to claim 2 , wherein
said power transmitting apparatus further comprises a driving device configured to change a position of said power feeder,
said controlling device controls said driving device to move said power feeder to a position where said power feeder is opposite to said power receiver if charging said power storing device is required on the basis of the detected power storage state, and controls said driving device to move said power feeder to a position where said power feeder is not opposite to said power receiver if charging said power storing device is not required on the basis of the detected power storage state.
6. The power transmitting apparatus according to claim 1 , wherein
the load is a lighting apparatus, and
said power transmitting apparatus further comprises a supporting device configured to hang and support the load, said power receiver, and said power storing device as a whole.
7. The power transmitting apparatus according to claim 6 , wherein
said power transmitting apparatus further comprises a driving device configured to change a position of said power feeder,
said controlling device controls said driving device to move said power feeder to a position where said power feeder is opposite to said power receiver if charging said power storing device is required on the basis of the detected power storage state, and controls said driving device to move said power feeder to a position where said power feeder is not opposite to said power receiver if charging said power storing device is not required on the basis of the detected power storage state.
8. The power transmitting apparatus according to claim 1 , wherein
said power transmitting apparatus further comprises a driving device configured to change a position of said power feeder,
said controlling device controls said driving device to move said power feeder to a position where said power feeder is opposite to said power receiver if charging said power storing device is required on the basis of the detected power storage state, and controls said driving device to move said power feeder to a position where said power feeder is not opposite to said power receiver if charging said power storing device is not required on the basis of the detected power storage state.
