Description

technical field [0001] The invention relates to an LED indoor desk lamp with wireless power transmission technology. In particular, it relates to an LED indoor desk lamp with the advantages of energy saving, low cost, wireless portability and the like. Background technique [0002] Since it was discovered in 1840 that the electromagnetic induction phenomenon and wires can be used to transmit electric energy, the transmission of electric energy is mainly carried out by the direct contact of the wires. The charging of electrical equipment is generally carried out through plugs and sockets, but when high-power charging is performed, this charging method has the risk of high-voltage electric shock. And due to friction and wear, the safety, reliability and service life of the system are relatively low, especially in some flammable and explosive fields such as chemical industry and mining, which can easily lead to major accidents. The new contactless power transmission system ad...
