Technical scheme
The purpose of this utility model is to overcome above-mentioned technological deficiency, and a kind of hand self-power generation type flashlight is provided.The utility model charging interval is short, does not influence flashlight work during charging, and discharge time is long, and discharge steadily can work long hours continuously.
The utility model is achieved through the following technical solutions:
A kind of hand self-power generation type flashlight, comprise housing, be arranged at the permanent magnet in the housing, coil, the rectification unit that is connected with coil is connected and forms the electric capacity and the lighting circuit in parallel with electric capacity in loop with rectification unit, described lighting circuit comprises power switch and the illuminator that is connected in series, it is characterized in that: described rectification unit also is connected with the rechargeable type lithium battery, and described rechargeable lithium battery is in parallel with electric capacity and lighting circuit.
Described lighting circuit also includes the current-limiting resistance of connecting with power switch and illuminator.
Described rectification unit is a bridge circuit.
Described rectification unit is a half-wave rectifying circuit.
Described permanent magnet is arranged at also can be reciprocating in coil in the coil.
Described illuminator is a semiconductor light-emitting-diode.
Described rechargeable type lithium battery is at least one.
Operation principle of the present utility model: pass coil cutting magnetic line generation induced-current repeatedly by the hand magnet that makes, induced-current is an alternating current, after the rectification of bridge heap, becomes direct current, and to lithium cell charging.When switch closure, make semiconductor light-emitting-diode luminous by lithium battery power supply.
Advantage of the present utility model is: owing to adopt magnet sectioned coil principle that lithium battery is charged, charging interval weak point, lithium battery length discharge time, discharge are steadily, owing to adopt semiconductor light-emitting-diode luminous, its electric current is little, power consumption economizes especially, but bright 72 hours of Chang Kaichang after the disposable charging.Can work long hours continuously reaches 72 hours, and simultaneously, lithium battery is charging on one side, on one side power supply, when charging, do not influence the luminous operate as normal of semiconductor light-emitting-diode.
