LED household night lamp capable of automatically changing lighting degree

Abstract

The invention relates to the technical field of semiconductors, and discloses an LED household night lamp capable of automatically changing the lighting degree. The lamp comprises a lampshade, a lampbody is fixedly installed at the top end of the lampshade, and a resistance wire is electrically connected to the lower end of the lamp body. A sliding piece is slidably connected to the resistance wire, an inflation air bag is fixedly installed at the left end of the sliding piece, a vent pipe is fixedly connected to the left end of the inflation air bag, and inflation devices are fixedly installed at the left end and the right end in the lampshade through connecting rods. The LED household night lamp capable of automatically changing the lighting degree is fixed through a rubber sucker, whenthe lampshade is shake manually, under the action of a movable ball body, the lampshade can shake left and right, and by matching the action of a moving rod, a rotating rod is driven to rotate arounda fixed rod and drives the inflation devices to move, so that the inflation air bag is inflated and expanded to extrude the sliding piece to move rightwards, and the resistance value of the resistance wire is changed, and accordingly the brightness effect of the lamp body is changed.

Description

technical field [0001] The invention relates to the technical field of semiconductors, in particular to an LED household night light which can automatically change the brightness level. Background technique [0002] The LED light is an electroluminescent semiconductor material chip, which is cured on the bracket with silver glue or white glue, and then the chip and the circuit board are connected with silver or gold wires, and the surrounding is sealed with special materials to protect the inner core wire. Function, and finally complete the packaging of the shell, so the LED has good shock resistance and is durable. LED lights can emit light of various colors. They are not only widely used in commercial advertisements but also in homes. Many home night lights use LED Lamps, on the one hand, can save electricity, on the other hand, LED lights can have a longer service life than incandescent lamps. [0003] Under the appeal of saving resources, more and more lights are made o...
