Abstract

The invention is applicable to the technical field of rechargeable lamp design, and provides a hand-operated rechargeable lamp which comprises a luminescence unit, a luminescence control unit, a rechargeable battery, a hand-operated generator driven by manpower to generate and output three-phase AC, a rectifier unit and a voltage stabilizing unit; in the voltage stabilizing unit, a semi-conductorswitching device provides a path for the rectifier unit to charge the rechargeable battery, and a three-terminal voltage reference source is used to stabilize the DC voltage output by a semi-conductor switch, a circuit structure is simple, the voltage is stabilized without any voltage reducing chip, thereby reducing the overall cost of the rechargeable lamp; and experiments have proven that the voltage stabilizing method can improve the charging efficiency of the circuit, thereby preventing the consumption of too much manpower in charging, and facilitating the use of a user.

Description

technical field [0001] The invention belongs to the technical field of rechargeable lamp design, in particular to a hand-cranked rechargeable lamp. Background technique [0002] The current hand-operated rechargeable lamp can realize the function of providing users with emergency use in workplaces without mains power. It has the advantages of energy saving, environmental protection, and convenient use. It is widely used in field operations, such as power grids, railway inspections, emergency rescue and disaster relief. , outdoor adventures, etc. [0003] This kind of hand-operated rechargeable lamp is recharged by hand-operating. Specifically, the manpower drives the hand-operated generator to output alternating current. After the alternating current is rectified and stabilized, the light-emitting unit is controlled by the control circuit to emit light. However, since the hand-operated rechargeable lamp provided by the prior art is stabilized by a step-down chip, it is nece...
