Description
technical field [0001] The invention relates to electric light source technology, in particular to a human body infrared sensor dimming LED lamp powered by a lithium battery. Background technique [0002] The quality of dressing table lighting affects the makeup effect. Although incandescent lamps have high color rendering and high power consumption, fluorescent lamps consume less power but have low color rendering. These two kinds of lights need AC power supply, which is inconvenient for occasions , cannot be used. Contents of the invention [0003] The purpose of the present invention is to provide dressing table lighting that is inconvenient to be powered by an AC power supply, a lithium battery powered dressing table human body infrared sensor dimming LED light that automatically turns on the light when people are on the dressing table and turns off the light after a delay when the person leaves. [0004] Technical solution of the present invention: a lithium battery-...
