Wireless power supply magnetic suspension table lamp with adjustable brightness

Abstract

The invention relates to a wireless power supply magnetic suspension table lampwith adjustable brightness which comprises a magnetic suspension base provided with a magnetic suspension machine core and a wireless transmission emitting assembly, and a magnetic suspension lighting assembly suspended below the magnetic suspension base, wherein the magnetic suspension lighting assembly comprises a coil fixing seat, a wireless transmission and receiving assembly, a magnet, a circuit board, a magnet base, a lamp holder fixing seat and a bulb from top to bottom, the magnet and the circuit board are fixedly installed on the magnet base, the wireless transmission and receiving assembly is fixedly installed on the coil fixing seat, the output end of the wireless transmission and receiving assembly is electrically connected with the circuit board, the coil fixing seat can move up and down relative to the magnet base. The power of the bulb is changed in a wireless mode, that is, the distance between the coil fixing seat provided with the wireless transmission and receiving assembly and the magnet base is adjusted to change the distance between the transmitting end and the receiving end, so that the output current is adjusted, and the current input into the wireless assembly cannot be changed in the adjusting mode, and the structure is simpler and more attractive.

Description

technical field [0001] The invention relates to a table lamp, in particular to a wireless electromagnetic suspension table lamp with adjustable brightness. Background technique [0002] The perfect combination of magnetic levitation technology and lighting technology has produced a magnetic levitation lamp. The bulb can be lit without physical contact with the power supply. The bulb is in a suspended state, giving people a super shocking visual enjoyment. For the magnetic levitation table lamp (such as the invention patent with the application number 201720962549.8), it mainly includes the magnetic levitation base placed at the set position and the light bulb under the magnetic levitation base, and the magnetic levitation base is equipped with a magnetic levitation core and a wireless transmission transmitting component , the light bulb is built with a levitation magnet matched with the magnetic levitation core and a wireless transmission receiving component matched with the...

AI Technical Summary

Problems solved by technology

This method needs to set columns and drains, and the structural design is relatively complicated

[0004] In addition, the lamp base and the lamp cap of the existing magnetic levitation desk lamp have an integrated structure, and the bulb needs to be dismantled and replaced when replacing the bulb, and the maintenance cost is relatively high

Furthermore, the existing maglev table lamp usually only has one light source, and the power of the light source is relatively small, so it is not suitable for main lighting, but only for auxiliary lighting.
