The present invention enables to turn on, off and dimming the illumination lamp formed by several fluorescent lamps and incandescent lamps at a long distance, such as a circular line, and at the same time, the incandescent lamp is automatically switched when the fluorescent lamp is turned off or turned off. When the incandescent light that can be adjusted is turned off and then turned on again, the remote control point, lighting and dimming circuit are designed to provide more convenience to the user by eliminating unnecessary operation by always turning on the first brightest normal state. It is about.

In the past, a device capable of remotely controlling a light point and an extinction from a remote location, such as that disclosed in Korean Utility Model Publication No. 892 (No. 87-3873), was used. It is composed of resistors and capacitors that are affected a lot, and thus malfunctions frequently occurred due to climate effects. Since the simple oscillation frequency is transmitted and received so that only simple "on" and "off" actions of fluorescent or incandescent lamps are performed, Disturbance occurs in the remote system due to the influence of the frequency of equipment such as TVs and cordless telephones, and it is not easy for users to control the intensity of incandescent lamps, which is necessary for the user's lifestyle and environment. Made me feel.

Therefore, this type of lighting fixtures can not be combined with incandescent bulbs at the present time when the fluorescent lights are colorized and the illuminance can be controlled. It was required to assemble the lighting into a luminaire such as a circline and to turn it off and on as needed, and to adjust the illumination freely.

The present invention has been devised in view of the conventional inconveniences and requirements as described in detail based on the accompanying drawings as follows.

1 is a circuit diagram of the transmitter of the present invention, which is configured to turn on and off a lamp by remote transmission and reception, wherein the contact point of the fluorescent lamp switch SW1 (SW2) and the incandescent lamp are adjusted. By properly sculpting the contacts of the switches SW3 and SW4, different digital pulses are generated by the pulse generator IC1 due to the oscillation of the oscillation element CBS, and transmitted through the infrared light emitting diode SP. The remote receiving IC (IC2) of the bipolar analog in the circuit receives it for decryption analysis through the decoder (IC3), and the analyzed signal is output through the power output terminal of the reader (IC3) and the series resistor (R11) When the analog signal for phase control of the photocoupler PC2, which is the converter output, is output in the reader IC3 through the diode D1 and D2 and connected to the base of the transistor Tr5, the transistor ( Fluorescent lamps PL1 (PL2) and incandescent lamps L3, which are connected to invert fluorescent and incandescent lamps respectively by absorbing ground through diode D4 in accordance with the inversion of Tr5), are automatically inverted by inverting circuit B. When the illuminance control support pulse is received, the illuminance of the incandescent lamp L3 is adjusted via the variable resistor Vr3 according to the phase control amount of the phase control photocoupler PC2, but when the input is turned off, When the lamp is turned off for a predetermined time and the lamps are turned off, the output of the IC3 is decoded through the resistor R7 and the capacitor C5, and the collector is connected to one terminal of the capacitor C4 and the resistors R4-R6. By applying to the base of the transistor Tr4 applied to the base of the transistor Tr3 through the power supply flowing from the collector of the transistor Tr2 to the emitter is stopped for a predetermined time by the time constant aberration by the resistor and the capacitor Is turned on the decoder (IC 3) is connected to reset so that the incandescent lamp L3 is always lit with normal brightness according to the linking operation of the reset circuit A.

The present invention configured as described in more detail as follows.

First, as shown in FIG. 1, the transmission signal for adjusting the illumination of the fluorescent lamps PL1 and PL2 and the illuminance of the incandescent lamp L3 is divided into the capacitors C24 to C27 having different capacities. Connected in series to each of the switches installed here, namely fluorescent lamps (PL1, PL2), off switch (SW1) (SW2) and incandescent lamp (L3), dimming control UP switch (SW3), DOWN switch (SW4) According to the pressure contact signal of the pulse generator IC1 of different digital pulses were oscillated at a specific frequency by the oscillation element (CSB).

That is, when the user presses a button that the user wants to control, the corresponding pulse is applied to the transistors Tr11 and Tr12 through the output terminal of the pulse generator IC1, so that the transistors Tr11 and Tr12 are turned on. By performing the 'off' operation, a predetermined pulse signal is remotely transmitted from the infrared light emitting diode SP. The output frequency at this time is determined by the values of the capacitors C24 to C27 connected to the respective switches SW1 to SW4. .

When the fluorescent lamp PL1, the dot, and the extinguishing switch SW2 are operated, the same pulse as the 3a diagram is sent out, and when the fluorescent lamp PL2, the extinguishing switch SW2 is operated, the same as the 3b diagram. Pulses are sent out, when the illuminance control UP switch (SW3) is operated to lower the incandescent lamp's illuminance, a pulse of the same form as 3c is output, and the illuminance control DOWN switch (SW4) is operated to lower the incandescent lamp's illuminance If it is, a pulse of the same type as the 3D diagram is sent.

Therefore, since the digital data is transmitted differently within the range that does not overlap with each other, it can be used as a centralized circuit that can operate a plurality of lights by one remote transmitter since there is no problem in operation even when receiving the data. Will be.

According to the signal of the remote transmitter, as shown in FIG. 2, the remote receiving IC IC2 remotely receives the transmitted signal as is known and sends the signal to the decoder IC3.

That is, the remote receiving IC (IC2) is a bipolar analog IC for amplifying and precisely filtering the detected transmission signal, and is composed of a light receiving diode (PH), a resistor, a capacitor, a limiter, a band pass filter, a demodulator, and a filter. After detecting the infrared signal transmitted from the transmitter through the light-receiving diode (PH), it detects only the pure signal of the received signal and reproduces a predetermined signal to be used only for the actual control, and inputs the decoder (IC3) through the transistor (Tr1). Application to the circuit converts the digital data according to the received waveform.

The decoder IC3 is configured such that a clock generated by the oscillation element CSB is input to the decoder and the converter through an oscillator and a timing generator provided in the decoder IC3.

Therefore, when the received digital data is analyzed and the data is for turning on the fluorescent lamp PL2, the reader IC3 outputs a predetermined signal for turning on the fluorescent lamp PL2 through the output terminal P. FIG. The signal is applied to the photocoupler PC1 through the resistor R8 to conduct it, so that the triac TAC1 is also conducted to turn on the fluorescent lamp PL2.

In addition, when a digital signal for turning on the fluorescent lamp PL2 is input and interpreted, a corresponding signal is output from the output terminal O of the reader IC3, so that the corresponding signal is inverted through the inverter 1 and then the resistor R20. ) Is applied to the input terminal A of the monostable multivibrator 2, which is readjusted according to the time constant determined by the capacitor C9.

Accordingly, a predetermined oscillation signal is output from the output terminal Q of the monostable multivibrator 2 and applied to the clock terminal CL of the flip-flop 3, where the output terminal P of the decoder IC3 is used. The output signal from the C1 is inverted through the resistor R19 and the transistor Tr8, and then input to the reset terminal R of the flip-flop 3, and a predetermined clock pulse is generated at its output terminal Q. Since the output signal is applied to the relay Ry via the inverter 4, the relay Ry is driven to turn on the fluorescent lamp PL1.

Here, the diode D7 connected to the collector of the transistor Tr8 and the diode D6 connected in parallel to the relay Ry are provided to absorb arbitrary data or to prevent back EMF.

And when a predetermined digital signal by the operation of the "UP" or "DOWN" switch SW3 (SW4) which is a signal for adjusting the illuminance of the incandescent lamp L3 is input and interpreted, the output of the reader IC3 is output. The corresponding signal is output through the terminal M and applied to the phase control photocoupler PC2 through the variable resistor Vr1, the resistor R17, the diode D5, and the resistor R18. The difference in the electromotive force output to the photocoupler PC2 which forms a closed circuit together with (R22) and the variable resistor (Vr3) is variable and passes through the magnetic terms R23 and R24 and the diac (DIAC) to the gate of the triac (TAC2). Since the conductance of the triac TAC2 is controlled by the value, the variable resistor Vr1 controls the conduction rate of the photocoupler PC2.

Therefore, the stabilized external input power is applied to the incandescent lamp L3 through the filter L so that the illuminance of the incandescent lamp L3 is automatically adjusted.

In using the present invention, when "OFF" for a while in the state of freely adjusting the illumination of the incandescent lamp and then "ON" again, it is always necessary to maintain the initial normal state, that is, bright state, in this case Since most of the data are analyzed and interpreted by the decoder IC3, the data is reset to maintain the decoder IC3 in the initial memory state.

The "A" part circuit of FIG. 2 is a reset circuit of the decoder IC3 analyzing data, and when the fluorescent lamp PL1 is "OFF" (all lights are turned off at this time), the power supply of the reader IC3 is temporarily cut off. The circuit is then supplied again.

For example, if the fluorescent lamp PL1 or PL2 is turned on while the illuminance of the incandescent lamp L3 is relatively low, the incandescent lamp L3 is automatically turned off and the fluorescent lamp PL1 is turned off. When all the luminaires of the lamp are completely turned off, the "OFF" pulse signal of the fluorescent lamp PL2 generated by the transmitting unit is inputted to the decoder IC3 through the remote receiving IC IC2, analyzed, and then analyzed by the output terminal P. Is sent out.

At this time, the output terminal of the reader IC3 is connected to the base terminal of the transistor Tr4 through the resistor R7 and the capacitor C5, and the collector terminal of the transistor Tr4 is the capacitor C4 and the resistors R4-R6. ) And the transistor Tr3, the power applied to the collector of the transistor Tr2 can be temporarily cut off, and the power applied to the reader IC3 is cut off. The instruction stored in the decoder IC3 is made in the initial state.

Accordingly, the command stored in the decoder IC3 analyzing the data is returned to the initial state, and when the incandescent lamp L3 is re-lit, the initial steady state illuminance is turned on.

When the incandescent lamp L3 is turned on during use, the fluorescent lamp PL2 is turned off automatically, and when the fluorescent lamp PL2 is turned on again, the incandescent lamp L3 should be automatically reversed. An inverting circuit that is a negative circuit will be described as an example as follows.

First, when the switch SW2 is operated to turn on the first fluorescent lamp PL2, when the fluorescent lamp PL2 is turned on through the above process, the output terminal of the reader IC3 connected between the resistor R7 and the resistor R8 ( The predetermined signal output from P is applied to the base of the transistor Tr5 via the resistor R8, the diodes D1 and D2, and the resistor R11, so that the transistor Tr5 is turned on so that the diode D4 is turned on. Is forward.

Therefore, the signal for turning on the incandescent lamp L3 output through the output terminal M of the reader IC3 does not flow through the variable resistor Vr1 and the resistor R18 to the photocoupler PC2 and through the diode D4 through the transistor ( Absorbed by Tr5), the incandescent lamp L3 is automatically turned off.

On the contrary, when the incandescent lamp L3 is turned on, the incandescent lamp L3 lighting signal analyzed by the reader IC3 is output through the output terminal M of the reader IC3, so that the resistor R14, the capacitor C7, and the resistor are output. (R12, R13) and variable resistor (Vr2).

On the other hand, the output signal from the other output terminal (P) is input to the base of the transistor (Tr5) through the resistor (R8), diode (D1, D2), resistor (R11) and inverted, so that diode (D4) is "OFF" do.

Therefore, since the signal through the converter output terminal M of the reader IC3 is connected to the photocoupler PC2 through the variable resistor Vr1 and the resistor R18, the illumination of the incandescent lamp L3 can be controlled. Since the predetermined signal output from IC3) and applied to the photocoupler PC1 is blocked, the fluorescent lamp PL2 is automatically turned off.

The present invention as described above is a centralized circuit system by the remote control of the circline type lighting equipment, which is a combination of several types of lighting by the point, turn off the light or adjust the illumination smoothly, but the fluorescent and incandescent light is automatically When it is inverted, and when the incandescent lamp with the illumination control is turned on again, it is a useful design to give the user more convenience by turning on the initial normal illuminance.
