Abstract

Disclosed is a passageway light control circuit demonstration model, which is used for teaching demonstration of circuit control principles of multiple-layer passageway lights. The adopted technical scheme is that the model comprises a direct-current power supply and LED lights and is characterized in that the power supply is disposed inside an insulating plate; circuits of the two poles of the power supply are led out; the circuit of one pole is sequentially connected with a double-pole single-throw switch K1, a double-pole double-throw switch K2, and a double-pole single-throw switch K3, then connected in parallel with the three LED lights, and finally connected with the other pole of the power supply; and each of the LED lights is connected with a resistor. The model is advantaged in that the model demonstrates the control principles of the multiple-layer passageway lights; the model is beneficial for direction introduction of the multiple-layer passageway control circuit principles; and the model has a simple structure.

Description

Corridor lamp control circuit demonstrating model

Technical field

The utility model relates to the circuit model that a kind of teaching demonstration is used, and for demonstrating the circuit control principle of multilayer corridor lamp, relates in particular to a kind of corridor lamp control circuit demonstrating model.

Background technology

In the physics teaching of junior-senior high school, the teaching demonstration of electricity is usually comparatively simple, and existing teaching demonstration instrument is also pressed close to people's life not, and in science popularization and teaching, the electric circuit teaching instrument of practicality comparatively lacks.

Summary of the invention

The purpose of this utility model is to provide a kind of circuit model of the circuit control principle for teaching demonstration multilayer corridor lamp.

For achieving the above object, the technical solution adopted in the utility model is:

A kind of corridor lamp control circuit demonstrating model, comprise direct supply, LED lamp, it is characterized in that, described power supply is placed in insulcrete inside, draw the two poles circuit, wherein connect with double-pole single throw K1, double-point double-throw switch K2, double-pole single throw K3 in order in a road, then in parallel with three LED lamps, finally with power supply, another extremely is connected, and wherein each LED lamp is connected with a resistance.

According to described corridor lamp control circuit demonstrating model, it is characterized in that, described resistance is 1K Ω.

The utility model has the advantage of, demonstration multilayer corridor lamp control principle, conveniently introduce multilayer corridor control circuit principle intuitively, simple in structure.
