Abstract

The invention provides a desk lamp capable of providing a wireless charging function for an electronic product. The desk lamp capable of providing the wireless charging function for the electronic product comprises a lamp support, a base seat, a power line, a lighting source and the like, and is characterized in that a wireless charger is arranged inside the base seat of the desk lamp, the power source of the desk lamp serving as energy of a wireless charging module is input, and generates a high-frequency alternating electromagnetic field through a high-frequency inverter circuit, a receiving end module picks up the energy of an emitting end by means of magnetic field coupling, and generates direct voltage and current to charge a battery of a load (for example, a mobile phone) through rectification and filtering. By means of the embedded design, defects of inconvenience and clumsiness produced in the use process of an independent wireless charger are reduced, convenience and usability of wireless charging technology are greatly improved, and user experience is improved.

Description

technical field [0001] The invention is a multifunctional desk lamp providing wireless charging for electronic products, and relates to the field of wireless charging for electronic products. Background technique [0002] Wireless charger is a device that uses the principle of electromagnetic induction to charge the electrical products at the receiving end in a non-contact manner. It is usually used in mobile phones, MP3, digital cameras and other electronic products. There is an inductance coil at the transmitting and receiving ends of wireless charging. The transmitting end is connected to a wired power supply to generate a high-frequency alternating magnetic field. current to charge the battery. The existing wireless chargers sold on the market are all independent charging devices, which require an independent power adapter, a separate external power supply, and a power cord connecting the adapter and the power socket. Such a design is often complained by users that it ...
