Description
Technical field
The utility model belongs to physics facility field, is specifically related to a kind of micro charge display.
Background technology
When junior physics explains simple electrical phenomena, all with silk and glass bar friction or fur and rubber bar friction, then contact with the Metal Ball of foil electroscope with glass bar or rubber bar, galvanoscopic paillon foil opening angle, at this moment teacher tells classmates, this is because with like charges on paillon foil, at this moment student often produces query.A kind of trace quantity electric charge is had now to show display, during use, as long as with a copperhead of hand-held firmly micro charge display, the copperhead of other end contacts with galvanoscopic Metal Ball, now just see that the luminophor of the inside sends aura from the flat window of micro charge display.But the light that luminophor sends is very faint after all, when dark, just can must see.Teacher demonstrates the used time, and student can't see at all.
Utility model content
The purpose of this utility model is to provide a kind of micro charge display, and the light that solution luminophor sends is very faint, when dark, just can must see.Teacher demonstrates the used time, the problem that student can't see at all.
The utility model relates to a kind of micro charge display, comprise darkroom and luminophor, the two ends in darkroom are sealed with ferrule, and luminophor is arranged in darkroom, luminophor two ends are connected with ferrule, darkroom is made up of horizontal darkroom and vertical darkroom, and luminophor and ferrule are arranged on horizontal darkroom, and vertical darkroom is provided with terminal block, luminophor is other is provided with photodiode, the bottom in vertical darkroom is provided with light emitting diode, and light emitting diode stretches out vertical darkroom, and terminal block is provided with amplifying circuit.
Amplifying circuit comprises light emitting diode, triode, photodiode and resistance, can receive the aura that luminophor sends, amplified, make lumination of light emitting diode, thus allow full class student see clearly by amplifying circuit by photodiode.
Compared with prior art, the utility model has the advantage of:
Structure is simple, cheap, easy to operate, can receive the aura that luminophor sends, amplified, make lumination of light emitting diode, thus allow full class student see clearly by amplifying circuit by photodiode.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the schematic diagram of the utility model amplifying circuit;
In figure: 1, light emitting diode, 2, vertical darkroom, 3, ferrule, 4, luminophor, 5, photodiode, 6, horizontal darkroom, 7, terminal block, 8, battery, 9, triode, 10, resistance.
Embodiment
Contrast accompanying drawing below, embodiment of the present utility model is described in further detail.
The utility model relates to a kind of micro charge display as illustrated in fig. 1 and 2, comprise darkroom and luminophor 4, the two ends in darkroom are sealed with ferrule 3, luminophor 4 is arranged in darkroom, luminophor 4 two ends are connected with ferrule 3, darkroom is made up of horizontal darkroom 6 and vertical darkroom 2, luminophor 4 and ferrule 3 are arranged on horizontal darkroom 6, vertical darkroom 2 is provided with terminal block 7, luminophor 4 is other is provided with photodiode 5, the bottom in vertical darkroom 2 is provided with light emitting diode 1, and light emitting diode 1 stretches out vertical darkroom 2, and terminal block 7 is provided with amplifying circuit.
Amplifying circuit comprises light emitting diode 1, triode 9, photodiode 5, battery 8 and resistance 10, can receive the aura that luminophor 4 sends, amplified by amplifying circuit by photodiode 5, makes light emitting diode 1 luminous, thus allows full class student see clearly.
During use, by a hand-held firmly ferrule 3, another ferrule 3 contacts with charged galvanoscopic Metal Ball, and at this moment luminophor 4 sends aura, and photodiode 5 receives the aura that luminophor 4 sends, photodiode 5 conducting.Make triode 9 base stage obtain voltage, triode 9 conducting, triode 9 collector has electric current to pass through, and makes light emitting diode 1 luminous.Resistance 10 plays the effect of adjustment triode 9 amplified current.
In sum, the utility model structure is simple, cheap, easy to operate, can receive the aura that luminophor sends, amplified, make lumination of light emitting diode, thus allow full class student see clearly by amplifying circuit by photodiode.
