Abstract
A wireless induction lamp includes a transmitter device for emitting wireless electric energy to a lamp receiver device, and the lamp receiver device includes a lamp housing having a transparent part disposed thereon, and a wireless light emitting device is disposed inside the lamp housing and in the transparent part. A first induction coil is disposed around on an outer edge of the wireless light emitting device, and receives the wireless electric energy of the transmitter device, to provide electric energy to the wireless light emitting device to emit light. The wireless induction lamp can wirelessly transmit electrical power to the light emitting element to emit light, so as to reduce disposal of electric wires, and the wireless light emitting device can be turned on/off by just changing a posture angle of the lamp housing to move close to or away from the electromagnetic range of the transmitter device.
