a desk lamp

Abstract

The invention discloses a table lamp, which comprises: a base provided with a power supply connection seat, a mounting seat provided with a light source, a connection assembly composed of a first pipe piece and a second pipe piece, and an electric wire is provided inside the connection assembly for locking The pipe fitting locking device of the first pipe fitting and the second pipe fitting, the electric wire unwinding device used for winding the electric wire, the first pipe fitting is provided with a magnetic part, and when the magnetic part moves close to the pipe fitting locking device, the magnetic part can be moved by the magnetic force Drive the pipe fitting locking device to unlock; when the magnetic part moves close to the electric wire unwinding device, the magnetic part can drive the electric wire unwinding device to unlock through magnetic force. When necessary, the relative movement of the first pipe and the second pipe can be controlled to move closer or farther away to adjust the overall length of the connection assembly, so that the distance between the light source and the irradiation target can be adjusted in a wider range, and thus the irradiation range of the light source can be adjusted to a greater extent , and the electric wire unwinding device can adjust the length of the electric wire, effectively protecting the electric wire.

Description

technical field [0001] The invention relates to the field of lamps, in particular to a desk lamp. Background technique [0002] With the continuous development of society, desk lamps have become an essential product for families or schools. Existing desk lamp generally adopts following structure on the market: comprise a base, a connecting rod is hinged on the base, and the upper end of connecting rod is hinged with a mounting base, and the mounting base is equipped with the light source that energizes and can emit light. When in use, the user can push the connecting rod to rotate, thereby driving the mounting seat to swing, thereby adjusting the height of the light source, and further adjusting the irradiation range of the light source. [0003] Although the above-mentioned desk lamp can adjust the irradiation range of the light source, the length of the connecting rod of the desk lamp is generally set to be relatively short in order to facilitate transportation or placeme...

Problems solved by technology

[0003] Although the above-mentioned desk lamp can adjust the irradiation range of the light source, the length of the connecting rod of the desk lamp is generally set to be relatively short in order to facilitate transportation or placement of the desk lamp. The height of the light source can be adjusted within the range, so the range of light source irradiation changes less
