Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a lighting control device that sequentially circulates and energizes a plurality of lighting loads from a plurality of control points.

Typical prior art connects in series or in parallel a load switch whose switching mode is changed by pulling the pull switch and a load switch whose switching mode is changed by remote control, and then The device is configured to supply power to lighting loads such as lamps, and for example, the sequential operation of turning on two lamps, turning on one lamp, turning on a small bulb, and turning off the light is repeated. In such prior art, the lighting load is controlled by a load switch operated by pulling the pull switch and a load switch operated by remote control.
Therefore, it may not be possible to change the lighting load to the desired lighting state or non-lighting state only by pulling the pull switch or by remote control.

Another prior art is a lighting device shown in Japanese Patent Application Laid-Open No. 54-144776. In this prior art, for example, a lighting light and a pull switch are installed on the ceiling, and while the pull switch is pulled, the illuminance can be changed automatically. When the desired illuminance is reached, if the pull switch is released, the illuminance can be changed immediately. It is possible to maintain the illuminance of Moreover, when the power is turned off and then turned on again, the brightness of the light source returns to the brightness that is most likely to be used by the user in a steady state, eliminating the hassle of having to reset the illuminance each time. . In such prior art, only a single pull switch is provided, and therefore the illumination lamp cannot be controlled from multiple locations.

Still another prior art is an automatic flasher with a timer disclosed in Japanese Patent Application Laid-Open No. 55-59679. In this prior art, lighting control operations are performed in which advertising lighting lights are turned on at sunset and turned off at midnight.In the evening, a decrease in the amount of ambient light is detected by a light detection circuit, and the advertising lights are turned on. This lighting time is measured by a timer, and the light is turned off when this set time has elapsed. Even with such prior art, it is not possible to control the lighting load to a desired state from multiple locations.

Another prior art is a load control device shown in Japanese Patent Application Laid-Open No. 55-111097. In this prior art, a flip-flop circuit is activated each time a power switch attached to a wall or the like is operated, and a plurality of states of the illumination lamp are switched and controlled according to the output of the flip-flop circuit. Even with such prior art, it is not possible to control illumination lights to a desired state from multiple locations.

Still another prior art is an emergency lighting device shown in Utility Model Application No. 48-114470, in which a switch section is controlled by the output of either a power failure detection section or a smoke detection device. Therefore, the emergency lighting system is configured to operate even if smoke is generated prior to a power outage in the event of a fire. Even in such prior art, the lighting load is not configured to be controlled to a desired state from multiple locations.

Some prior art is disclosed in Japanese Patent Application Laid-Open No. 51-90778. In this prior art, a changeover switch for changing the illumination state of a lighting lamp, a pull switch operated by pulling a string, a power switch, and a logical sum of the outputs of the pull switch and the power switch are used to operate the changeover switch. and a circuit for switching.

In such prior art, no consideration is given to what happens after a power outage occurs. Therefore, after the power is restored, the illumination state will be the same as it was immediately before the power outage, and therefore, after the power is restored, the illumination may be performed at a high illuminance even though it is not necessary, resulting in wasted power consumption.

Furthermore, if the pull switch remains operated, it becomes impossible to operate the changeover switch.

An object of the present invention is to enable a desired lighting state, for example, a miniature light bulb lighting state, after the power outage is restored;
Another object of the present invention is to provide a lighting control device that can control the lighting load even if an unexpected condition occurs, such as when a pull switch is pulled.

FIG. 1 is an electrical circuit diagram showing the basic structure of the present invention. This lighting control device includes a remote control device 3 as a pulse generating means consisting of a transmitter 1 and a receiver 2, and a so-called control switch that is shut off by a pulling operation and is conductive when the pulling operation is not performed. By means of the normally closed pull switch 4, the lighting loads 5, 6, and 7 can be controlled to turn on or off. The transmitter 1 has a function of transmitting infrared, ultrasonic, or radio wave signals by manual operation of a push button or the like provided therein. Receiver 2 receives the signal from transmitter 1 . The line 8 from which the output of the receiver 2 is derived goes high when the receiver 2 receives a signal from the transmitter 1, and goes low when it does not. Line 8 is connected to line 10 via buffer 9 and pull switch 4. On line 10,
Integrating circuit 1 consisting of a resistor 55 and a capacitor 60
1 is connected, and the integrated output from this integrating circuit 11 is given to a Schmitt circuit 12. The output from the Schmitts circuit 12 is connected to the transistor 13
given on the basis of. Transistor 13 is connected in series to coil 15 of self-holding stepping relay 14 . The stepping relay 14 is
A load switch 1 that sequentially and cyclically changes the switching state each time the coil 15 is excited.
6, 17, and 18. Lighting load 5, 6, 7
are connected in series to switches 16, 17, and 18, respectively. Power is supplied from the power supply 19 to the lighting loads 5-7 via these switches 16-18. A pull-up resistor 20 is connected to the line 10 to keep the line 10 at a high level.

FIG. 2 1 shows the transmitter 1 in the remote control means 3.
2 shows the waveform of the signal derived from the transmitter 2 to the line 8 by the operation of the oscillator 2. Here, the pulse width W3 is the period during which the transmitter 1 is operated, and may be different for each pulse. Line 8 becomes high level by this pulse width W3. The signal waveform on line 10 is shown in FIG. Here, the pulse width W4 is the period during which the pull switch 4 is pulled and cut off. This pulse width W4 may be different for each pulse. When the pull switch 4 is pulled and cut off, the line 10 is brought to a high level by the pull-up resistor 20. The output waveform of the integrator circuit 11 which integrates the signal from line 10 is shown in FIG. The Schmitt circuit 12 level-discriminates the output from the integrating circuit 11 and applies a signal having the waveform shown in FIG. 2 to the base of the transistor 13. stepping relay 14
Each time the transistor 13 becomes conductive and the coil 15 is excited, the switching mode of the switches 16 to 18 is changed as shown in FIGS. 25 to 7, respectively. Note that the circulation method of the contacts of the stepping relay may be different. It should be noted that the switching mode of switches 16-18 is changed in response to the rising edge of the output from Schmitt circuit 12. This rise occurs when the transmitter 1 is operated and the receiver 2 outputs a high level signal to the line 8 and the pull switch 4 is not pulled, and when the pull switch 4 is pulled and the line 10 is pulled up to the pull-up resistor 20.
This is when it is brought to a high level by During the period from time t1 to time t2 shown in FIG. 2, the switches 16 and 17 are turned on and the lighting loads 5 and 6 are energized, and thus two lights are turned on. During the period from time t2 to time t3, the switch 17 is turned on and only one light of the lighting load 6 is lit. Time t3~
During the period t4, only the switch 18 is lit and the lighting load 7 is lit. The lighting load 7 is, for example, a miniature bulb, and the lighting loads 5 and 6 may be lamps that consume more power than the miniature bulb.
During the period from time t4 to time t5, the switches 16 to 18 are shut off, and the lighting loads 5 to 7 are turned off. Thereafter, such operations are repeated sequentially and cyclically.

The integrating circuit 11 and the Schmitt circuit 12 prevent the illumination loads 5 to 7 from being erroneously controlled due to noise applied to the receiver 2 or noise generated by the chatter of the pull switch 4 or the like.

FIG. 3 is an electrical circuit diagram of one embodiment of the present invention. Parts corresponding to the above-described embodiment shown in FIG. 1 are given the same reference numerals. It should be noted that in this embodiment, the output from the Schmitt circuit 12 is input to a register 23 including flip-flops 21 and 22, and the output from the register 23 controls the lighting loads 5-7. Triaxes 24 to 26 as load switches are connected in series between the lighting loads 5 to 7 and the power source 19, respectively. These triaxes 24-26 are cut off when lines 27-29 are at high level, and conductive when lines are at low level. DC power supply 30 supplies stabilized DC power to operate these circuit elements.

In register 23, flip-flop 2
1 and 22 have a set input terminal S and a reset input terminal R, and when a high level signal is input to these terminals S and R, the output terminal Q and the output terminal are set to high level. When a pulse is applied to the clock input terminal C, a high level or low level signal at the data input terminal D is delivered to the output terminal Q at the rising edge of the pulse. The signal from the output terminal of flip-flop 21 and the signal from the output terminal of flip-flop 22 are applied to a NAND gate 56. The output from NAND gate 56 is provided on line 27. The output terminal Q of flip-flop 22 is connected to line 28. The output terminal of flip-flop 21 and the output terminal Q of flip-flop 22 are connected to the input of NAND gate 31, respectively. NAND
The output of gate 31 is provided on line 29.

A high potential side line 32 of the DC power supply 30 is connected to one terminal of a capacitor 34 included in a power failure recovery setting circuit 33. The other terminal of the capacitor 34 is grounded via a resistor 35. A junction 36 between capacitor 34 and resistor 35 is connected to reset input terminal R of flip-flop 21 and set input terminal S of flip-flop 22.
A capacitor 37 is connected to the line 32 .

Assume that the power supply 19 returns from a power outage. The voltage on line 32 varies as shown in FIG. As a result, at the connection point 36 of the power failure recovery setting circuit 33, due to the differential action of the capacitor 34, the fourth
A pulse having the waveform of FIG. 2 is generated. As a result, flip-flop 21 included in register 23 is reset and flip-flop 22 is set. The output terminal of flip-flop 22 is low, so the output of NAND gate 56 and line 27 are high. Also, output terminal Q of flip-flop 22 and line 28 are at a high level. Therefore, the triaxes 24 and 25 are cut off. The output terminal of flip-flop 21 is at high level. Thus, the output from NAND gate 31 and line 29 go low and triac 26 becomes conductive. Therefore, the lighting load 7 is turned on, and the lighting loads 5 and 6 are turned off. The lighting load 7 is, for example, a miniature bulb as described above, and its power consumption is smaller than that of the lighting loads 5 and 6, so that a large inrush current is prevented from flowing into the power supply 19 at the time of recovery from a power outage. In addition, the lighting load such as this miniature ball 7
By lighting up after the power is restored, a general household can know that there was a power outage while they were away, and it also reduces power consumption while they are away, and allows them to adjust various equipment installed in the house. It is convenient to be able to do this.

Next, in this state, the Schmitt circuit 12 is activated by operating the remote control device 3 and the pull switch 4.
The pulse shown in Fig. 5 is input to the register 23 from
Assume that it is input after t1. The output waveforms of the output terminals of the flip-flops 21 and 22 are as follows.
These are shown in FIGS. 2 and 5, respectively. The output waveform of the output terminal Q of the flip-flop 22 is shown in FIG. The flip-flop 21 starts from time t1.
At t5, the stable state is changed at the rising edge of the pulse applied to the clock input terminal C as described above. Flip-flop 22, which receives the reset output of flip-flop 21, changes its stable state upon the rising edge of the reset output of flip-flop 21.

During the period from time t1 to time t2, the output terminal of flip-flop 21 is at a low level, so
The output of NAND gate 31 becomes high level,
Triack 26 shuts off. In this way, all of the lighting loads 5 to 7 are turned off.

During the period from time t2 to time t3, the outputs from the output terminals of flip-flops 21 and 22 are both at high level, so the output from NAND gate 56 and line 27 are at low level. As a result, the triac 24 becomes conductive and the lighting load 5 lights up. The output waveform from NAND gate 56 is shown in FIG. As shown in FIG. 5, the output waveform of the output terminal Q of the flip-flop 22 is at a low level during the period from time t2 to t4, thereby making the triac 25 conductive and the lighting load 6 Light. In this way time t2~t3
During the period, the two lights of the lighting loads 5 and 6 are turned on.

During the period from time t3 to time t4, the output terminal of the flip-flop 21 is at a low level, so
The output of the NAND gate 56 becomes high level,
Triax 24 is therefore cut off. At this time, since the output terminal Q of the flip-flop 22 remains at a low level, the triac 25 remains conductive. In this way, only one lamp of the lighting load 6 is turned on.

During the period from time t4 to time t5, the output terminal Q of the flip-flop 22 becomes high level, and the triac 25 is cut off. At this time, since the output terminals of flip-flops 21 and 22 are both at high level, the output of NAND gate 31 is at low level. Therefore, the triax 26 becomes conductive. In this way, a signal having the waveform shown in FIG. 5 is derived from the NAND gate 31. In this way, only the lighting load 7 is turned on, returning to the original state.

When a momentary power outage occurs, the capacitor 37 included in the power outage recovery setting circuit 33 is temporarily discharged and the operation of the lighting control device continues. Therefore, the register 23 will not be set to the stored contents after the above-mentioned power recovery.

FIG. 6 is a partial electrical circuit diagram of another embodiment of the present invention, in which parts corresponding to those of the previous embodiment are given the same reference numerals. A noteworthy feature is that the pull switch 38 is a so-called normally open switch that is closed when no pull operation is performed, and becomes conductive when the pull switch 38 is pulled. Line 10 is a pull switch 38
When the pull switch 38 is made conductive by pulling the button, it becomes high level. pull switch 38
When the line 10 is not pulled and a high level signal is not applied to the line 8 from the remote control device 3, the line 10 is kept at a low level by the resistor 39.

FIG. 7 is a partial electrical circuit diagram of still another embodiment of the present invention, in which parts corresponding to those of the previous embodiment are given the same reference numerals. In this embodiment, the receiver 2a in the remote control device 3 has a function of receiving the signal from the transmitter 1 and outputting a signal that becomes low level to the output line 8 when the lighting loads 5 to 7 are to be controlled. . In this embodiment, an inverting circuit 40 is interposed between the output line 8 and the pull switch 4.

FIG. 8 is a partial electrical circuit diagram of another embodiment of the invention. Parts corresponding to those in the previous embodiment are given the same reference numerals. In this embodiment, a fixed position installation switch 41 is provided, which is installed at a fixed position in the house, such as on the wall of the house. This switch 41
is a so-called normally closed switch that is conductive when not operated, and is shut off by manual operation.
Line 8 is connected to the connection point between switch 41 and resistor 43. When switch 41 is not operated and conductive, line 8 is at a low level. By operating the switch 41 and shutting off,
Line 8 becomes high level.

FIG. 9 is a partial electrical circuit diagram of another embodiment of the invention. In this embodiment, the signal from the receiver 2 of the remote control device 3 is applied from line 8 to the base of PNP transistor 42. When oscillator 1 is not operated, the output from receiver 2 on line 8 is low, so transistor 42 is conductive and line 58 is low.
When oscillator 1 is operated, oscillator 2 causes line 8 to go high, which causes transistor 42 to shut off and line 58 to go high.

FIG. 10 is a partial electrical circuit diagram of yet another embodiment of the invention. Receiver 2 of remote control device 3
is applied to the base of transistor 44. Resistor 4 connected in series to transistor 44
5 is grounded to low level. The resistor 45 has
A capacitor 46 is connected in parallel to prevent malfunction. The resistance value of the pull-up resistor 20 is
Select a resistance value that is sufficiently larger than the resistance value of 5. This turns off transistor 44 and keeps line 10 low when pull switch 4 is conducting. When the transmitter 1 of the remote control device 3 is not operated and the transistor 44 is cut off, the line 8
is low level. When transmitter 1 is operated and receiver 2 conducts transistor 44, line 8
becomes high level.

In each of the embodiments described above, when the operating push button provided on the transmitter 1 of the remote control device 3 remains operated, for example by remaining in contact with an obstacle, the line 8 goes high. The level will remain the same. Therefore, even if the pull switch 4 is pulled, a rising waveform cannot be obtained, and the lighting or extinguishing states of the lighting loads 5 to 7 cannot be changed.
Such problems are solved by the embodiment shown in FIG. By operating the transmitter 1 of the remote control device 3, the transmitter 2 outputs a high level signal to the line 8. The high level signal from line 8 is inverted by inverting circuit 47. An inversion circuit 49, a resistor 50, and an inversion circuit 51 are connected in series to the inversion circuit 47. Inversion circuit 47, 4
A pull switch 4 is connected between the connection point 52 of the resistor 50 and the connection point 53 of the inverting circuit 51.
is connected. The output from the inverting circuit 51 is applied via the integrating circuit 11 and the Schmitt circuit 12 to the transistor 13 or the register 23 as in the previous embodiment. The resistor 50 is interposed to prevent the inversion circuit 49 from being destroyed when the pull switch 4 is conductive.

FIG. 12 shows the waveform of the signal derived from the receiver 2 of the remote control device 3 on the line 8. The period during which the transmitter 1 was operated is indicated by the pulse width W3. The output waveform of connection point 52 is shown in FIG. 12. When the pull switch 4 is pulled, the connection point 53 changes by the pulse width W4 as shown in FIG. 12. The output from the inverting circuit 51 is the 12th
It is shown in FIG. The output from the integrating circuit 11 is shown in FIG. The output waveform from Schmitt circuit 12 is shown in FIG.

When the transmitter 1 and the pull switch 4 of the remote control device 3 are operated at different times, the pulses at times t1a and t2a from the Schmidt circuit 12 corresponding to the times t1 and t2 shown in FIG. The lighting or non-lighting states of the lighting loads 5 to 7 change depending on the rise of the light.

It is assumed that the transmitter 1 of the remote control device 3 remains operated during the period from time t3 to t6, and the pull switch 4 is operated only during the period from time t4 to t5. When the pull switch 4 has not yet been operated and is therefore conductive, that is, during the period from time t3 to t4, the low level output from the inverting circuit 47 is provided to the inverting circuit 51 via the pull switch 4. When the pull switch 4 is pulled and cut off at time t4, the low level output from the inverting circuit 47 is inverted by the inverting circuit 49 to become a high level, and is transmitted to the inverting circuit 51 via the resistor 50. Given. Therefore, when the transmitter 1 is operated at time t3, the lighting loads 5 to 7 are controlled by the rising waveform from the Schmitt circuit 12 at time t3a. Furthermore, the lighting loads 5 to 7 are controlled by the rising waveform at time t5a from the Schmitt circuit 12, which corresponds to the time t5 when the pull switch 4 is turned on when the pull switch 4 is pulled and released. .

During the period from time t7 to time t10, pull switch 4
Assume that the transmitter 1 of the remote control device 3 is operated from time t8 to t9 while the tension operation remains. When the pull switch 4 is pulled and cut off and the transmitter 1 of the remote control device 3 is not yet operated, that is, during the period from time t7 to t8, the line 8
is low level. The signal from line 8 is transmitted through inverting circuits 47, 49, resistor 50 and inverting circuit 5.
1 to the integrating circuit 11. Therefore, the time at which the output from the Schmidt circuit 12 rises, which corresponds to time t7 when the pull switch 4 is pulled.
At t7a, the lighting or non-lighting states of the lighting loads 5 to 7 change. When line 8 becomes high level for a period from time t8 to time t9 due to the operation of transmitter 1, at time t9 when the operation of transmitter 1 is interrupted.
At time t9a when the output from the Schmitt circuit 12 corresponding to rises, the lighting loads 5 to 7 are controlled. In this way, while either the remote control device 3 or the pull switch 4 is being operated, the lighting load can be freely controlled by the other one.

As still another embodiment, the transistor 13 in the embodiment of FIG. 1 is replaced with a transistor that conducts when the base is at a low level, or the resistor 23 in the embodiment of FIG. 3 is replaced with a resistor that responds to a falling edge. Moreover, pull-up resistor 2
Instead of 0, a pull-down resistor may be provided between the line 10 and a low-level ground potential.

As described above, according to the present invention, the remote control means 3
By means of the transmitter 1, the pull switches 4, 38, and the fixed position installation switch 41, the register 23 can be brought into a desired logic state, thereby causing the switching elements 24, 24, corresponding to that logic state.
25 and 26 can be operated to control the lighting loads 5, 6, and 7.

Further, according to the present invention, the reversing means 49, 50 are provided, whereby even if one of the transmitter 1 or the pull switch 4 remains operated, the lighting load is controlled by operating the other. be able to.
