Abstract

The utility model provides a remote and contact controlling light regulator. The technical point is that the remote and contact controlling light regulator comprises an infrared launcher, a receiving and preamplification circuit, a phase inversion power amplification circuit, a light regulating circuit, a contact input circuit and a bulb. An infrared receiving signal is sent to the 6 pin of the IC after the phase inversion and the power amplification. A contact plate is connected with the 5 pin of the IC. The 8 pin of the IC is connected with the control electrode of a controlled silicon. The light regulating principle is that a trigger signal is sent out by the 8 pin after the action of the input signal. The conducting angle of the controlled silicon is changed continuously to change the brightness of the bulb. The utility model has the advantages of complete function and good performance. The remote and contact controlling light regulator is suitable to be used as the switch of the illumination lamp indoors.

Description

Remote and contact controlling light regulator

The utility model belongs to a kind of electronic light modulator that is used for lighting bulb.

The development of household electrical appliance switch is maked rapid progress, the switch relevant with the utility model mainly contains two kinds: 1, utilize remote controller to control the switch of household electrical appliance, be suitable mature technique, and use quite general, such as the television set with distant control function, video tape recorder and bulb etc., bring great convenience for people's life; 2, the soft-touch control that utilizes the CMOS chip to make also begins to occur on market.Above-mentioned two kinds of switches all do not have dimming function.

The purpose of this utility model provides a kind of remote control touch dimmer of holding concurrently, and is used for controlling bulb.

The purpose of this utility model is achieved in that it is made up of infrared transmitter, reception and pre-amplification circuit, commutation power amplifier, light adjusting circuit, touch input circuit etc., characteristics of the present utility model are: the commutation power amplifier is served as by insulation P-channel enhancement type field effect transistor V, light adjusting circuit is made up of ic chip and bidirectional triode thyristor SCR, 8 pin of IC are received the trigger end of SCR, the input of pre-amplification circuit is received the grid of field effect transistor V, 6 pin of IC are received in the drain electrode of field effect transistor, touch sheet and receive 5 pin of IC, bidirectional triode thyristor and bulb series connection.The utility model has two kinds of control bulbs (be signal input) mode, below its operation principle of division:

1, remote control mode: infrared transmitter sends the 38KHz infrared signal, after the infrared receiving tube reception, amplify through pre-amplification circuit, output to the grid of V pipe by its output, this moment, the grid of V pipe became electronegative potential by high potential, thereby make the drain electrode of V pipe become high potential by electronegative potential, this circuit signal is input to remote signal input 6 pin of IC through resistance, IC is the integrated circuit with dimming function, when control signal act on below 0.4 second the time, IC only plays on-off action: when input signal acted on more than 0.4 second, IC entered dimming state, the triggering signal of its 8 pin output, controlling the angle of flow of bidirectional triode thyristor, changing the brightness of bulb, be transferred to suitable brightness and stop input signal, light will be stabilized in this brightness intraoral illumination, if send into a signal of closing again, after lamp extinguished, brightness degree deposited in its circuit automatically, when turning on light once more, still keep this brightness.

2, touch manner: hand palpate diaphragm, signal enter touch input 5 pin of IC, the output of 8 pin, and its light modulation principle is identical with above-mentioned " remote control mode ", so slightly.

The utility model has compared with prior art increased dimming function and has touched input mode, provides bigger convenience to the user.

Further specify the utility model below in conjunction with accompanying drawing.

Fig. 1 is a theory diagram of the present utility model.

Fig. 2 is an electrical schematic diagram of the present utility model.

It is made up of infrared transmitter, reception and pre-amplification circuit, commutation power amplifier, light adjusting circuit, touch input circuit and bulb, be characterized in: the commutation power amplifier is served as by insulation P-channel enhancement type field effect transistor V, light adjusting circuit is made up of LS7232 and bidirectional triode thyristor SCR, 8 pin of IC are received the trigger end of SCR by R11, the input of pre-amplification circuit is received the grid of field effect transistor V, 6 pin of IC are received in the drain electrode of field effect transistor by R6, touch sheet and receive 5 pin of IC, bidirectional triode thyristor, bulb and coil L series connection by R10.The utility model has two kinds of control bulbs (be signal input) mode, below its operation principle of division:

1, remote control mode: infrared transmitter sends the 38KHz infrared signal, after the infrared receiving tube reception, amplify through pre-amplification circuit, output to the grid of V pipe by its output, this moment, the grid of V pipe became electronegative potential by high potential, thereby made the drain electrode of V pipe become high potential by electronegative potential, this circuit signal is input to remote signal input 6 pin of IC through resistance, IC is the integrated circuit with dimming function, when control signal act on below 0.4 second the time, IC only plays on-off action; When input signal acts on more than 0.4 second, IC enters dimming state, and the triggering signal of its 8 pin output is being controlled the angle of flow of bidirectional triode thyristor, change the brightness of bulb, be transferred to suitable brightness and stop input signal, light will be stabilized in this brightness intraoral illumination, if send into a signal of closing again, after lamp extinguishes, brightness degree when turning on light once more, still keeps this brightness from depositing in its circuit.
