Abstract

The invention relates to the technical field of lighting devices, and discloses a table lamp mechanism capable of automatically adjusting light brightness. The table lamp mechanism comprises a base, wherein a support rod is fixedly connected to the top part of the base, and a brightness meter is fixedly connected to the top part of the base. According to the table lamp mechanism capable of automatically adjusting lamplight brightness, the brightness meter controls a motor to rotate by detecting the brightness of a bulb and the ambient brightness, a first rotating disc further drives a second rotating disc to rotate, at the moment, connecting rods eccentrically rotates on the rotating discs, the position relation between a sleeve rod and a resistance wire is changed, and therefore the effect of changing the contact region between the resistance wire and the sleeve rod is achieved; and due to the fact that the contact area of the resistance wire and the sleeve rod is changed, the lengthof the resistance wire between a first power connection point and a second power connection point is changed, the resistance connected into a circuit is further changed, the brightness of lamplight ischanged accordingly, and the effects of automatically adjusting the brightness of the lamplight and reducing damage of the lamplight to eyes are achieved.

Description

technical field

[0001] The invention relates to the technical field of lighting devices, in particular to a desk lamp mechanism that can automatically adjust the brightness of light. Background technique

[0002] Desk lamp, refers to the electric lamp that is placed on the table and has base, is a kind of illuminator commonly used, and desk lamp is small and exquisite, easy to carry, is convenient to reading, study and work. With the continuous development of the appearance of desk lamps in recent years, desk lamps have far surpassed the value of desk lamps themselves. Desk lamps have become a work of art. Nowadays, there are many types of desk lamps. Bulbs are divided into energy-saving lamps, incandescent lamps, LED bulbs, etc. The control methods include switch control, touch control, brightness adjustable, voice control and so on.

[0003] The working principle of the brightness-adjustable table lamp is a resistance-capacitance phase-shifting circuit composed of resisto...
