Abstract
The motivation of this paper, when camping outdoors, we are afraid of running out of electricity, so we can generate electricity by hand-cranking. We use a small AC generator, high-capacity lithium-ion batteries, and high-brightness LED lights to make the control circuit, LED driver circuit, voltage regulator circuit, and USB charging and discharging circuit, and the brightness is adjustable in three steps. It can also be used as cell phone mobile power. Keywords: Emergency Lighting, LED, Camping light
