Description of drawings
Fig. 1 is the utility model circuit diagram.
Fig. 2 is the utility model external structure sketch map.
The specific embodiment
Map 1 and Fig. 2; The light emitting diode V1 that is provided with multi-resonant oscillating circuit unit, lighting circuit unit, loudspeaker Y in the cylindrical shell 1 of this flashlight and is used for detection feedback information; Adopt the 6V dc source; Multi-resonant oscillating circuit adopts the NE555 chip, and the output pin of NE555 is that pin 3 is connected with the B socket; Light emitting diode V1 is anodal to be connected with power supply, and its negative pole is set to the A socket; The grounding pin of NE555 is that pin 1 is connected with the C socket, and loudspeaker is connected with the B socket through triode VT1; The reset pin of NE555 chip is provided with socket D.The lighting circuit unit comprises LED luminous tube and the constant-current drive circuit AMC7135 chip that is connected with power supply.Loudspeaker Y also is connected in series with a K switch 1, and power supply is connected with multi-resonant oscillating circuit unit or lighting circuit unit through selector switch K2.Light emitting diode V1, A, B, C, D socket and K switch 1 and selector switch K2 all are arranged on the cylindrical shell, and the LED luminous tube is arranged in the lamp holder.
The method for using of the utility model is following:
One, do the illumination time spent and cast aside pass K1 and push a two, AMC7135 can decide the high-capacity LED of electric current output promotion 1W with 350mA, and lamp brightness is splendid.
Two, purposes can be made the tester of transistor quality; Also can go out burglar alarm for the passengers and the illumination usefulness, A, B, C, D make the metal jack, metal jack A, B, C are used for doing the transistor testing jack; When test diode; Two pins are inserted in A, C two holes respectively, are inserted in to see on A, the C bipod whether V1 is bright to the bipod of diode conversely again, if having only under a kind of situation the bright explanation diode of V1 normal basically; And the anode that can judge diode when V1 is bright is to be inserted in the A hole, and negative electrode is in the B hole.If two kinds of situation lamps are all bright or all do not work, explain that diode is bad.When measuring triode: be inserted into three pin of triode respectively the position that pushes K2 this moment connection on A, B, three jacks of C; If this moment, V1 was bright; And Y sends loud this triode fashion of cry explanation; If what the NPN type was inserted A is the colelctor electrode of triode, what insert B is base stage, and what meet C is emitter stage.If what positive-negative-positive was inserted A is the emitter stage of triode, what insert B is base stage, and what meet C is colelctor electrode.Operation principle is multi-harmonic-oscillations frequency of oscillation f=1.44/ (R1+2R2) C1 that R1 (39K), R2 (82K), C1 (0.022uF) and IC1 (NE555) form, and frequency is about 320Hz, and the audio frequency of 3 pin output promotes the Y sounding after the triode that will measure amplifies.
Also can test the triode that to measure and whether have amplifying power,, can judge the amplifying power that to survey triode roughly according to the size of sound.
Three, the enforcement of travelling antitheft illumination flashlight: K1 receives a, and K2 connects Y.Use the Great Wall Software that has two plugs carefully to add the lead of insulating barrier, be inserted into respectively on C, two sockets of D.Several kinds of embodiments are arranged: 1. the wallet antitheft is placed on little flashlight in the wallet zip up.The lead that carefully adds the Great Wall Software that has two plugs insulating barrier is inserted in two plugs on C, the D socket around hanging on the key chain of wearing.In case break lead, the loudspeaker in the flashlight are just named, and report to the police.Plug, jack can be made screw-shaped.2. the lead that carefully adds insulating barrier to the Great Wall Software that has two plugs is on the pull head snap close of the slide fastener of traveling bag, and flashlight is placed in the traveling bag, and two plugs are inserted on C, the D socket will break lead in case spur slide fastener, and loudspeaker will be reported to the police.
