Description
Technical field:
The invention belongs to the device that relates to a kind of lecture experiment.
Background technology:
Existing bulb and battery do lecture experiment, and material object is too little, are difficult to see clearly, put also not sideJust, the poor effect of lecture experiment.
Summary of the invention:
Replace bulb and battery to do the device of lecture experiment with LED lamp and battery, provide one to inhaleBe attached to the device of the lecture experiment on magnet board, demonstration is convenient, and mold former is large, is convenient to seeExamine good demonstration effect.
Replace bulb and battery to do the device of lecture experiment with LED lamp and battery, by LED lamp mould,Battery mould and wire composition.
LED lamp mould M1, has absorption magnet N1-4; Link A1, that link A2 meets rectifier bridge D1-4 is defeatedEnter end, rectifier bridge D1-4 output termination LED lamp LED1, link A2 meets metal screw socket screw thread T,And between link A1, there is isolated insulation material G.
Battery mould M2, has absorption magnet N5-8, is serially connected with three battery E, and battery E negative pole connects negative poleOutput E2, battery E positive pole meets cathode output end E1 through resistance R 1, and triode Q1 emitter stage connects electricityPond E positive pole, triode Q1 base stage meets cathode output end E1 through resistance R 2, the voltage-stabiliser tube VD1 of serial connection, triode Q1 colelctor electrode one tunnel through light emitting diode TD1, resistance R 3 to battery E negative pole; Three utmost pointsPipe another road of Q1 colelctor electrode through sound circuit B to battery E negative pole.
Wire L is copper flexible circuit conductor, and its two ends are with absorption magnet N9-10.
While doing lecture experiment, its device has absorption magnet, can be adsorbed on magnet board battery mouldTool M2 first contacts with two links of LED lamp mould M1, and two other link connects with wire againConnect, in LED lamp mould, have positive-negative polarity conversion rectifier bridge D1-4, the positive antipole access of battery,LED lamp can be luminous; Battery mould cathode output end E1 and cathode output end E2 cause short circuit straight-throughTime, flowing through resistance R 1 intensifying current, resistance R 1 becomes battery short circuit protective resistance, anodal outputEnd E1 becomes zero potential, and the negative terminal of voltage-stabiliser tube VD1 becomes zero potential, and voltage-stabiliser tube VD1 conducting, through electricityResistance R2, triode Q1 conducting, light emitting diode TD1 is luminous, sound circuit B sounding, acousto-optic is carriedThe short circuit of waking up connects, and should correct immediately.
Effect: replace bulb and battery to do the device of lecture experiment with LED lamp and battery, its device hasAbsorption magnet, can be adsorbed on the magnet board of iron plate, does lecture experiment convenient, mould mouldType is large, is convenient to observe; In LED lamp mould, there is positive-negative polarity conversion rectifier bridge, battery positive and negativeUtmost point access, LED lamp can be luminous, and LED lamp is low in energy consumption, energy-conservation demonstration,When battery mould output forms short circuit connection, acousto-optic is reminded.
Brief description of the drawings:
Fig. 1 replaces bulb and battery to do the formation picture of device of lecture experiment with LED lamp and battery. M1For LED lamp mould, M2 is battery mould, and L is wire, and N1-10 is absorption magnet.
Detailed description of the invention:
Replace bulb and battery to do the device of lecture experiment with LED lamp and battery, as shown in Figure 1, itsDevice has absorption magnet, can be adsorbed on the magnet board of iron plate, does lecture experiment convenient,Mold former is large, is convenient to observe.
M1 is LED lamp mould, and M2 is battery mould, and L is wire, and N1-10 is absorption magnet. Rectifier bridgeD1-4 is positive-negative polarity change-over circuit, the positive antipole access of battery, and LED lamp can be luminous; WireL is copper flexible circuit conductor, and its two ends, with absorption magnet, are convenient to connect; Resistance R 1 value is 47 Ω-1K Ω, makes the two ends of LED lamp LED1 lower than its rated voltage, and battery E is three No. seven batteriesOr button cell serial connection, or select as required; Mould can be with the materials such as foamed plastics, embeddingEnter electronic circuit; Metal screw socket screw thread T can paste and form with aluminium foil or aluminium; Q1 is positive-negative-positiveTriode, VD1 is voltage-stabiliser tube, B is sound circuit.
While doing lecture experiment, its device has absorption magnet, can be adsorbed on magnet board battery mouldTool M2 first contacts with two links of LED lamp mould M1, and two other link connects with wire againConnect, in LED lamp mould, have positive-negative polarity conversion rectifier bridge D1-4, the positive antipole access of battery,LED lamp can be luminous; Battery mould cathode output end E1 and cathode output end E2 cause short circuit straight-throughTime, flowing through resistance R 1 intensifying current, resistance R 1 becomes battery short circuit protective resistance, anodal outputEnd E1 becomes zero potential, and the negative terminal of voltage-stabiliser tube VD1 becomes zero potential, and voltage-stabiliser tube VD1 conducting, through electricityResistance R2, triode Q1 conducting, light emitting diode TD1 is luminous, sound circuit B sounding, acousto-optic is carriedThe short circuit of waking up connects, and should correct immediately.
