Table lamp applying adjustable light controller

Abstract

The invention discloses a table lamp applying an adjustable light controller. The table lamp comprises a control base, a lamp pole and a bulb, wherein an LED light source is mounted in the bulb; the lamp pole is made from a metal material; the light controller is mounted in the control base; a TP connecting interface is arranged in the lamp pole; the light controller comprises a power supply circuit and a regulating circuit, and the signal input end of the regulating circuit is connected with the TP connecting interface, so that a person can realize the brightness regulation of the table lampby touching the lamp pole, signal input equipment, such as a TP touch screen, does not need to be additionally arranged for the table lamp, and the production cost of the table lamp is reduced; the table lamp adopts a PWM dimming mode, so that the table lamp cannot have LED chromatographic offset phenomena and has high dimming precision; and besides, the table lamp has various infinite dimming modes, intelligent dimming can be realized, power consumption is reduced, energy is saved, and the environment is protected.

Description

technical field [0001] The invention relates to a lighting fixture, in particular to a desk lamp using an adjustable lighting controller. Background technique [0002] With the improvement of people's living standards, people's requirements for interior decoration are getting higher and higher. Desk lamp is a kind of lamp, which is used for indoor lighting and decoration, and many desk lamps use thyristor dimming method, but the dimming mode is relatively single. , and during the dimming process, the desk lamp is easy to cause instability in the internal circuit due to insufficient maintenance current under low load conditions. In addition, the dimming knob used in the desk lamp is easy to be damaged due to excessive temperature under long-term working conditions. Burn out, if use touch screen, can increase the cost of desk lamp, have reduced the market competitiveness of product. Contents of the invention [0003] In order to overcome the deficiencies of the prior art, t...
