Description

technical field [0001] The invention relates to the technical field of charging, in particular to an illumination device, a bidirectional wireless charging device and a control method thereof. Background technique [0002] Wireless charging technology is derived from wireless power transmission technology, which can charge lighting equipment without using power cords, improving the convenience of charging. [0003] At present, wireless charging technology mainly adopts three schemes: electromagnetic induction, magnetic field resonance and radio wave, among which the electromagnetic induction solution is currently the most common wireless charging scheme. However, when using the principle of electromagnetic induction coil for wireless charging, the energy flows from the primary coil to the secondary coil, transferring energy from the transmission end to the receiving end. Only one-way transmission of energy can be realized, and the usage scenarios are limited. Contents of t...
