A power generation device is composed of a hollow cylinder, a loop coil, a moveable high strength permanent magnet and auxiliary magnets fixed on both ends of the hollow cylinder, wherein, the loop coil is formed by a plurality of circles of wound metallic and conductive wires arranged in an interlayer of the hollow cylinder. A voltage limitation full bridge rectifier, a current limiter, a voltage re-limitation device and a large volume capacitor are used as power storage devices. A luminescent device is composed of a luminous diode and convex lenses. The utility model has the advantages of simple structure, low cost, convenient use, small volume, light weight, etc.
Description
Technical field
The utility model relates to a kind of lighting apparatus.
Background technology
Traditional flashlight is to provide electric energy by dry cell, if the electric weight of dry cell loses electric energy because of exhausting or place for a long time in using, will influence the normal use of flashlight, particularly in case of emergency, and when not having reserve battery, will cause unnecessary trouble.In addition, traditional flashlight also exists cost height and the problem that easily causes second environmental pollution.For addressing the above problem, numerous no battery flashlight innovation and creation are arisen at the historic moment.Described no battery flashlight generally is to utilize mechanical driving device to drive a microgenerator, gives a micro battery energy storage.Though it has overcome above-mentioned every shortcoming that the flashlight of dry cell power supply exists, exist complicated in mechanical structure, parts cost height, volume greatly and problem such as Heavy Weight.
Summary of the invention
Power generation type described in the utility model illumination torch can solve the problem of the big and Heavy Weight of complicated in mechanical structure, parts cost height, volume that traditional no battery hand tube exists.
Power generation type illumination torch solution of the above problems described in the utility model is as follows: the hollow cylindrical shell of flashlight is a double-decker, twines electromagnetic induction coil in its interlayer; In cylindrical shell, be fixed with the auxiliary permanent magnet of first and second piece on the both ends of the surface respectively, other has the 3rd high strength permanent magnets to be positioned in the described cylindrical shell by activity; More than three magnets press the adjacent arrangement of identical polar; Also be fixed with an energy storage device that is connected with described electromagnetism sense coil output in the described flashlight; This energy storage device comprises rectification circuit, be connected to the voltage-stabiliser tube of rectification circuit output end and be connected on the storage capacitor of rectification circuit output end; Described storage capacitor is connected with light-emitting device by a connection switch.
Aforesaid power generation type illumination torch is characterized in that: described light-emitting device can be that one or more high brightness LEDs and convex lens are formed.
Aforesaid power generation type illumination torch, it is characterized in that: described connection switch can be made up of moving magnet and a tongue tube.
Power generation type described in the utility model illumination torch is compared with traditional flashlight, have simple in structure, cost is low, and is easy to use, volume is little and advantage such as in light weight.
Description of drawings
Fig. 1 is the elevation cross-sectional view of power generation type illumination torch described in the utility model;
Fig. 2 is the circuit theory diagrams of power generation type illumination torch described in the utility model.
The specific embodiment
The TRT of this device comprises the induction coil 2 that is placed in hollow cylindrical shell 3 interlayers, is fixed in first block permanent magnet 1, second block permanent magnet 6 of both ends of the surface in the cylindrical shell 3, is movably placed in the 3rd block permanent magnet 10 in the cylindrical shell 3.Electric storage device comprises diode bridge rectifier D2-D5, the pressure limiting circuit D1 that is connected on induction coil 2 two ends that is connected on induction coil 2 two ends, the zener diode W that is connected on rectification circuit output end and big capacity storage capacitor C.Described storage capacitor C should be more than 1F.Described storage capacitor is connected with light emitting diode by a K switch, and electric energy is provided.Described K switch can be fixed near the tongue tube of connecting the switch 5 by the connection switch 4 with magnet and one to be formed.Described light emitting diode can be single or several compositions.Described circuit part 9 can be packaged in the torch.The cloche 7 of torch can be convex lens structures.
This device is used Faraday's electromagnetic induction law, has made TRT.It utilizes two auxiliary magnets, when solving movable magnet and in tube, moving back and forth, and the problem that can bump with two ends not.By along the axial waggle TRT of hollow cylinder the time, promptly the high strength permanent magnet is done quick relative motion between the circuit coil by some circle plain conductor coileds, thereby produces induced electromotive force in the loop of coil, reaches the purpose of generating.
The electric energy that is produced by TRT is by pressure limiting, full-bridge rectification, current limliting, charge to accumulate element electric capacity after the pressure limiting again, with power storage on capacitor C, thereby reach accumulate can purpose.
Described connection switch 4 is positioned at the torch outside, is made by fluorescent material, also can see its position at night.When sliding this connection switch, its drives magnet and moves to dry reed switch, makes the closing of contact of dry-reed tube switch, connects electric storage device and light-emitting device; Adopt this structure can prevent that traditional switch contact is oxidized and because of the issuable electric spark of break-make.
Light-emitting device is made up of high brightness LED, and it also comprises convex lens.Because LED is luminous to be spot light, disperse, therefore need convex lens, be converted into directional light, make it become the light source that certain practical value is arranged.
