Problems solved by technology
This will have no effect on conventional living room lamps, ceiling lamps, ceiling lamps and other lamps, but for desk lamps, it is inconvenient to connect wires. The original desk area is already very limited, plus books and computers piled on the desk.
[0004] Therefore, those skilled in the art have designed a battery-powered desk lamp, which is powered by a rechargeable battery and LED lamp beads, but it cannot be guaranteed that the rechargeable battery is always in a sufficient state during use. The battery is charged to prevent power supply interruption, so the problem of inconvenient use caused by using the connecting wire to realize the power supply of the LED desk lamp is still not solved

The invention discloses an LED lamp and a power supply circuit thereof. The power supply circuit comprises a power supply battery, an electromagnetic receiving coil, a wireless charging module, a voltage conversion module and a battery protection module, and the electromagnetic receiving coil is electrically connected with the wireless charging module; the wireless charging module is electricallyconnected with the voltage conversion module, and the voltage conversion module and the battery protection module are electrically connected with the power supply battery. Through the electromagneticreceiving coil, the wireless charging module, the voltage conversion module and the battery protection module, a wireless charging function of a power supply battery in the LED lamp and a charging anddischarging protection function of the power supply battery are realized; the charging function of the power supply battery is realized without using a connecting wire, so that inconvenience is not brought to a user in the use process.
Description
technical field [0001] The invention relates to the technical field of LED lighting, and more specifically relates to an LED lamp and a power supply circuit thereof. Background technique [0002] With the popularity of LED light sources, more and more consumers choose LED lamps as their daily lighting supply. [0003] Since the LED beads on the LED lamps are DC power supply devices, the power supply structure of the existing LED lamps generally includes a rectifier module, a filter module, and a step-down regulator module. The rectifier module is used to convert the input 220V AC power supply Electricity is converted into direct current. For this reason, common LED lamps need to use physical wires to connect the LED lamps to the mains input end to obtain the 220V AC mains. This will have no effect on conventional living room lamps, ceiling lamps, ceiling lamps and other lamps, but for desk lamps, it is inconvenient to connect wires. The original desk area is already very li...
