Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an outdoor lighting control device that is applied to lighting loads installed outdoors, such as porch lights and garden lights.

In general, lighting loads installed outside the home, such as entrance lights and SRS lights, are turned on at night when it gets dark outside, and conversely turn off when it gets bright outside in the morning. However, in one equation such as 0,
The lighting load remains lit from the time the lighting load is turned on until it is turned off in the morning.
This has the drawback that even in the middle of the night, unnecessary power is supplied to the lighting load, and in ordinary homes, the lights are left off in order to save power.

Therefore, conventionally, the light is turned on until a certain period of time has elapsed after the light is turned on, and when the timer setting time is reached,
A lighting control type that automatically turns off the lights has been proposed, but if there are unexpected visitors and it is dark around the house,
The drawback was that it gave a bad impression to visitors. Therefore, the present inventor attempted to use a lighting control power type that automatically reduces the brightness of the lighting load after the timer time has elapsed to save power. Even if the lighting load becomes unnecessary before the timer time elapses, there is a problem that it is not possible to freely dim the light.2 If you try to force the dimming control, the wall switch in There was a problem in that the lighting load had to be connected with at least eight wires.

The present invention was developed in consideration of these problems in the conventional example, and it turns on the light when it gets dark outside and automatically dims after the timer setting time has elapsed. It is an object of the present invention to provide an outdoor lighting control device that can change the lighting state of an outdoor lighting load from a wall switch provided through a two-wire transmission line.

The configuration of the present invention will be described below with reference to the drawings. 1st
The figure is a diagram showing the configuration of a lighting control device using the lighting control power type according to the present invention. In the figure, (1) is the power supply circuit for driving the circuit, and (2) is the outdoor brightness. This is a daylight sensor for detecting. FIG. 2 (IL) shows the output of the daylight sensor (2).

As shown in the figure, at night, the output of the daylight sensor (2) becomes H level. However, the daylight sensor (
The long timer (3) is reset while the timer (2) is detecting external light. Therefore, when the daylight sensor (2) no longer detects outside light, the long timer (3)
) Since the K reset is no longer applied, the long timer (3
) starts the counting operation. (4) is a power failure detection circuit connected to the power supply circuit (υ), and is shown in Fig. 2 (
As shown by A, B, and CK in the figure b), when <am is cut off, a short time timer (5) is activated. (
6) is the main lighting, and (7) is the auxiliary lighting, and the former is brighter than the latter.

(8) is a lamp switching circuit, which changes the lighting lamp (6) (7) according to the output of the long timer (3) and short timer (6).
) so that it can be switched. However, when it gets dark outside, the bright main illumination light (6) is turned on as shown in Figure 2 (2) K, and the long time timer (3) K reset signal is no longer sent. (3) starts the counting operation. When this long-time timer (3) reaches a time-up state due to the elapse of time tl as shown in Figure 2 ((1)), the output of the acid circuit (8a) is used to supplement the lighting from the main illumination lamp (6). The short timer (6) starts operating when the wall switch (9) is turned off and the power is turned off. ) is turned off is measured by a short time timer (5), and if the time when the wall switch (9) is turned off is longer than the time tl as shown in Figure 2 (0), the main light is turned off. The light (6) lights up.

If the time is short, an auxiliary illumination light (7) is turned on. In addition, when the lighting load is switched to the main lighting lamp (6) due to this K, the long time timer (3) is started again, and after a predetermined period of time, the lighting load is switched to the auxiliary lighting lamp (7) again. be. Here, switch the wall switch (9
) is turned off (KL), the short-time timer (5) is driven by a buffer amplifier capacitor provided in a power supply circuit (υ) designed for one-circuit operation. In FIG. 1, the voltage waveforms in the portions marked with amh correspond to the operating waveforms in FIG. 2 (IL) to color).

FIG. 8 shows a specific 5j! of the present invention. First, (1) is a power supply circuit, and its smoothing capacitor is designed to maintain a charged state for a while even if the wall switch (9) is turned off for a short time. Capacity is set. (2) is a daylight sensor 91. When it is bright outside, the Vcri phototransistor 4 is in an on state, and therefore the output voltage level of the Schnitt inverter ua becomes H level. Therefore, this Schuett inverter (6) is connected to the -power input NO.
Since the output of R circuit a3 is at L level, relay 114
1 is not excited.

The main illumination light (6) is not turned on, and the other NOR circuit (
Since the output of 7-lip 70-tub Q19 also becomes L level, the relay aη is not excited and the auxiliary illumination lamp (7) is not turned on.
(3) is a long time timer, which sets the time for switching the main illumination light (6) to the auxiliary illumination light (7). To the output of the reset input RFiNOR circuit (to) of the long timer (3)! 1iIt, and is reset when the output of the NOR circuit (to) is at L level. However, when it is bright outside, the K beam setting manual force R is at the L level, so the long time timer (3) is being reset. The output T of the long time timer (3) becomes L level when reset, and becomes H level when the timer reaches 5 times. (4) is a power failure detection circuit, and # is because the power supply voltage is always at H level.

The inverted output of the inverter is at L level, and the output of the new power supply detection circuit (4) is at L level. As a result, capacitor αItj is not charged and PUT (21) does not operate.

However, when it gets dark outside, the 7-ototransistor a1 gradually becomes in a state of high resistance and 1. The terminal voltage of the capacitor @ gradually increases as shown in FIG. When the terminal voltage of capacitor (1) exceeds the threshold level of Schmitt inverter (4), the output of Schmitt inverter (51121) becomes L level as shown in FIG. By the way, since the output of the double inverter @ (Figure 984 (E)) is normally at L level, the output of the NOR circuit (To) (Figure 4 (H)) is at H level. The reset is released and the counting operation starts.-The Q output of the cuff lip 7o knob αe (Fig. 4 (g)) is held at the L level.Therefore, both the NOR circuit 00 and the power outputs are at the L level. , its output (I!4 diagram ((sub)) is at H level, the transistor (to) is turned on and relay a is energized. Next, the relay contact (141L) is closed. The main illumination light (6) lights up.The long-time timer (3) continues counting and when the time t1 elapses, the output T goes high as shown in Figure 4.
level, and the NOR circuit power ((2) in FIG. 4) becomes L level. Therefore, the reset human power R of the 7 lip 7o tube 1e becomes L level, and the 7 lip 7 o tube (1
The Q output of No. 11 becomes H level. Therefore, one input of the KN'OR circuit becomes H level, and the NOR circuit a3
The output becomes L level. This button is a transistor @
is turned off, and the main illumination light (6) is turned off. - Since the input riHL of the Cadran Sister is a bell,
The relay Uη is driven, the relay contact (17&) closes, and the auxiliary illumination light (7) lights up. Therefore, the timer of the long timer (3) causes the illumination to switch to the main illumination light (6).
It switches from the light to the auxiliary illumination light (7).

Next, consider the case where the wall switch (9) is turned off. Figure 4 (
When the wall switch (9) is turned off as shown in (a), the terminal voltage of the small capacitor (c) quickly drops.

Therefore, the output of the inverter (4M4 diagram O) becomes H level. The power supply for driving this inverter (to) and other circuits is supplied from a large-capacity back-piston capacitor (1 (iK). When the output of inverter a- becomes H level, the differential circuit surface A rising differential waveform is obtained at the output (Fig. 4, 09).
Therefore, the output of the NOR circuit (to) becomes L level instantaneously,
For this purpose, input R of 7 ritsufu 7o tsubu (to).
A negative logic reset pulse is input to the Q output, and the Q output becomes H level. For this reason, the auxiliary illumination light (77) lights up and the main illumination light (6) goes out. - The output of the power inverter a8 becomes H level, and the short-time timer (5) starts charging the hot water a. When the terminal voltage of the capacitor tls (Fig. 4) exceeds the gate voltage of Purr (to), PUT (2G) becomes 418 and the charge of the capacitor IjaS is discharged. Therefore, - of the NOR circuit (to) Since the force input becomes an instantaneous H level, the output of the NOR circuit becomes an instantaneous L level.

For this purpose, a negative logic set pulse is input to the set force S of 7 rip 70 to α. At this time 7 rip 7
Since the Q output of the O tube (161) becomes L level, the main illumination light (6) turns on and the auxiliary illumination light (7) goes out. Also, before PUT (to) becomes conductive, that is, the time tg If the wall switch (9) is returned to the ON state before Kri has passed, the reversal of the flip 70 knob αe will not occur, so only the auxiliary illumination light (7) will be turned on.In this way, When the wall switch 9) is turned back on, the output voltage of the inverter a returns to the L level, so that the charge in the capacitor ttS is quickly discharged. Note that this short timer (5) is a simple CR.
It is also possible to configure the circuit by connecting a three-way inverter to the output of the integrating circuit.

Fig. 5 shows different examples of the power supply circuit (υ) and the power failure detection circuit (4). is connected, and when the wall switch (9) is turned off, a smaller current than in normal times flows through the impedance element (to) to the power supply circuit (υ). This is to obtain the voltage.This eliminates the need for a backup power supply in the electric circuit (υ).-1
The voltage detection circuit (4) includes a comparison circuit 181), a reference voltage generation circuit using a voltage dividing resistor, and a capacitor a.
It consists of a CR integrator circuit including ll, and ii.
When the switch (9) is turned off, the terminal voltage of the KFi capacitor (to) decreases and becomes below the reference voltage generated by the reference voltage generation circuit, and the output of the comparison circuit cIυ becomes L level.By the way, as shown in Fig. 116. In the embodiment, since the reference voltage applied to the positive comparison input of the comparison circuit 3υ begins to drop below K when the wall switch (9) is turned off, both comparison circuits may operate depending on the value of one circuit element. The embodiment shown in Fig. 6 is an improvement on this point, and uses a constant voltage circuit consisting of a Zener diode and a transistor μs to keep the reference voltage constant and convert it into a comparator circuit. This ensures the operation of 3υ.

FIG. 7 shows an embodiment in which the long-time timer (3) and short-time timer (5) are also used as a nine-timer for timing 1-j. In the same figure, (86!L) is an oscillation circuit for supplying to the counter and generating zero pulses, and the oscillation frequency of this oscillation circuit (86a) is
Output circuit (86a) via the switch (8 &) (i)
It is determined by the time constant of the CR element provided in the long-time setting section (8b) and the short-time setting section (6b) connected to. (2) is a daylight sensor, and when it is bright outside, the output of K is at H level. Therefore, the output of the OR circuit is at H level, the Q output of the SRV lip 70 is at H level, and the Q output of the SRV lip is at L level. Then, the lighting control transistor (2) of the auxiliary illumination light (7) is turned off. Also, in this state, the ishiverter aIO output is at L level, so the AN
The output of the D circuit becomes L level, and the transistor for controlling the lighting of the main illumination light (6) is turned off. Therefore, neither the main illumination light (6) nor the auxiliary illumination light (7) are turned on while it is bright outside.

Next, when it gets dark outside, the output of the daylight sensor (2) goes to L level and the output of the inverter goes to H level, so the AND circuit power goes to H level, and the main illumination light (6
) is lit. In addition, since the reset force R of Haya Katsuri also becomes L level, the counter starts the gaunt operation. Here, the Q output of the SR7 lip 70 knob 1 is normally at L level, and the analog 0 switch (8a) is turned on, and the CR element is provided in the long-time setting section (3b) and the 9 CR element is connected to the oscillation circuit. (86 &) K connected. For this reason, a relatively long-period 90 check pulse is supplied to the counter, and after a predetermined time t1 has elapsed, the counter enters a time-up state and its output T becomes H level. By the way, Anna 0 Tasuit 9
(6) Since the Q output of FiSR flip 70 tube 14υ is at L level, it is in a conductive state, and then when the output T of counter 14 becomes H level, the output of OR circuit 143 becomes H level.
L level and L SR flip 70 knob 13!19 is reset and its output QFiL level and output QFi
It becomes H level. Therefore, the transistor (2) for controlling the lighting of the auxiliary illumination lamp (7) is turned on. -Force SR
Since the output of the V lip 70 is at the QrjL level, the output of the %AND circuit is also at the L level, and the transistor □□□ for lighting control of the main illumination lamp (6) is turned on. By the above-described operation, the main illumination light (6) is turned off after one hour t1 after the main illumination light (6) is turned on, and the auxiliary illumination light (7) is turned on in its place.

Next, when the wall switch (9) is temporarily turned off 1aL/C, set input S of the lip 7o knob-υ
A positive pulse of K instants is applied which causes SR7
Since the Q output of the Ripf D circle reaches the riH level, the analog 0 switch (8a) and 1tari become non-conductive, and instead of 1, the analog 0 switch (5a) and -~ become conductive. Also, the way the differential circuit comes out is the manual reset of the SR7 lip via the OR circuit.
．． Therefore, when the wall switch (9) is turned on, the Q output of the SR flip 7o amplifier goes to L level, and the output power goes to H level. Therefore, the auxiliary illumination light (7) is turned on and the main illumination light (6) is turned off. Furthermore, since it is also applied to the reset human power R in the counter diagram via the output OR circuit +41 of the differential circuit I, when the wall switch (9) is turned off, the btl: It starts the operation. Since the oscillation circuit (86L) is connected to the OCR element in the short-time setting section (5b) via the analyzer switch (5a), it generates relatively short-cycle clock pulses. Long time setting section (5
b) is connected, the counter diagram shows a shorter time t! This causes a time-up condition.

By the way, if the wall switch (9) returns to the on state 111 before the counter diagram reaches the time-up state, the output of the power cutoff detection circuit (4) returns from the H level to the L level, so that the inverter η The output rises from L level to H level. Therefore, the output of the dividing circuit 4 is instantaneous H.
level. For this reason, the output of the OR circuit also instantaneously relevels fc, the SR flip 70 tube i4υ is reset, and its output Q becomes L level. The analog zero switch (8a) and R42 become conductive again, and the analog zero switch (5a) and frame become non-conductive, and the operation of the counter as a short-time timer (5) ends. r.

It continues to operate as a long-term timer (3). When the counter chart reaches a time-up state in this state, the output T becomes H level, and the human power R for resetting the clip 7O becomes H level through the analog output switch and the OR circuit.

However, since the SR clip 0 knob μs#'i wall switch (9) was re-set in one unit at the time of ORKL&, no change occurred, and the auxiliary illumination light (7)
Only the light will remain lit.

Next, considering the case where the wall switch (9) is kept in the off state 11 for a relatively long time, the counter function is set by the short timer (6).
), and after 1 hour and 1 m have elapsed, the output T becomes H level. Therefore, the setting force S of the SR7 lip 70 becomes H level through the analogue shift switch and OR circuit G17), the output Q of the SR flip 70 becomes H level, and the output QriL level. As a result, the main illumination light (6) lights up, and the auxiliary illumination light (6) lights up on the opposite side.
7) is turned off. Also, when the Q output of the SR7 rip 70 rises from L level to H level, the counter diagram is reset via the differentiating circuit and the OR circuit, and the SR7 rip 0 is reset via the OR circuit. Since the human power R for setting υ of −υ instantaneously becomes H level, its output Q
becomes L level. For this reason, Ana0ta Switch (3a)
Then, the mouse becomes conductive and the counter starts operating as a long time timer (3) again. Therefore, when the counter reaches the time-up state, its output T resets the SR" lip 70, the main illumination light (6) goes out, and the auxiliary illumination light (1) turns on. In this way, the main illumination light ( 6) is always in the ON state only for a predetermined time t1 determined by the long time timer (3), and is a trap so as to contribute to power saving.

Next, the dormitory 1m4fil in Figure 8 shows an example of a circuit in which the lighting status of the main lighting (6) and auxiliary lighting (1) is reversed each time the wall switch (9) is turned off. ing.

In FIG. 11, the timer (51) is composed of multistage registers, an oscillation circuit, etc., and when reset human power R is applied, all internal registers are reset and the timer enters the start state. However, when the predetermined time tl elapses and a time-up state occurs, the output T switches from the L level to the H level. (52) FiD V lip 70 knobs,
The Q output is connected to the D input, so that the outputs Q and Q are alternately inverted each time the 0 input C rises. The power interruption detection circuit (4) is
Each time the connected wall switch (9) is turned off, a pulse of positive polarity is output.

When it is bright outside, the output of the M9°C sensor (2) (FIG. 9(a)) is at the H level, and therefore the inverter (58) is at the FiL level. For this AND
The output F (FIG. 9(f)) of the circuit (64) is at L level, the main illumination light (6) does not turn on, and the daylight sensor (2) does not turn on.
) is the ninth KD flip 70 tube whose output is H level (
62) set input 5FiH level, output QFi
Figure 9 (+1) KH level as shown by K, output is 9th
As shown in the figure (•)K, it becomes the KL level. Therefore, the auxiliary illumination light (7) is also not lit. Further timer (61)
is the H of the daylight sensor (2) via the ORIgl path (66).
It is reset by the level signal, and the output T is L
level.

Next: Think about nine times when it gets dark outside.

Since the output of the daylight sensor (!) becomes I/iL level, the output of the inverter (68) becomes H level, and the AND circuit (
Since the output of 54) becomes H level, the main illumination light (6) is turned on. During this period, the output P of the differentiating circuit (56) becomes H level at Kli as shown in FIG. 9(g)K, and the OR
The timer (51) is activated via the circuit (55) at 913 in FIG.
Reset as shown, but after that the daylight sensor (
Since the output of step 2) is at L level, the timer (61) is no longer applied. Therefore the timer (5
1) is activated immediately after the main illumination light (6) is turned on,
After a certain period of time t1 has elapsed, the output T is shown in Figure 9 (0).
It becomes H level like r. This is K, so D7 lip 70
The knob (52) is reset, and the output becomes the QriL level, and on the contrary, the output becomes the QIIiH level. As a result, the main illumination light (6) goes out and the auxiliary illumination light (7) is replaced by one.
) lights up.

゛Also, if the wall switch (9) is turned off (11) while the main illumination light (6) is on, the power failure detection circuit (4) will output a signal as shown in Figure 9 (
b) The pulse of the positive pole is output as shown in K, and the DV
The outputs Q and Q of the lip 70-) (52) are inverted. This turns off the main light (6) and turns off the auxiliary light (7).
lights up. Similarly, when the wall switch (9) is turned off while the auxiliary illumination light (7) is on, a positive pulse is output from the power failure detection circuit (4), and the D7 lip
The outputs Q and Q of the knob (52) are inverted. This turns off the auxiliary illumination light (7) and turns on the main illumination light (6).

However, in this case, when a pulse of positive polarity is instantaneously output from the differentiating circuit (56), it becomes K, so the OR circuit (66)
), the timer (51) is reset and starts counting. When a predetermined time tI elapses after the main illumination light (6) is turned on, the output T becomes H level and D
-7 lip 7o knob (52) is reset. Therefore, when the main illumination light (6) is turned on, the auxiliary illumination light (7) is always switched on after a predetermined time t1 has elapsed, thereby saving power. It is.

The present invention is configured as described above, and is reset when the main illumination light is turned on, and after a predetermined period of time has elapsed, the illumination light switching/lighting means switches the main illumination light off and turns on the auxiliary illumination light. Since it is equipped with a timer that outputs a control signal, when the main lighting lamp with a large amount of light is turned on,
After a predetermined period of time, it always switches to the auxiliary lighting, which has a lower amount of light, so the main lighting often remains on while it is dark outside.Therefore, night lighting outside the layer wastes electricity. Even if the main lighting is turned off, the auxiliary lighting is always on while it is dark outside, so even if there are unexpected visitors, it will give a good impression to the visitors. This has the advantage that it does not cause any damage, and is also desirable in terms of crime prevention. Furthermore, in the present invention, a detector/stage is used to detect a drop in the line voltage of a power supply line, and an off-operation such as an off-time or an off-count of a wall switch is determined based on the output of an electrical disconnection detection means. Off 4, which determines the situation and outputs a lighting light switching control signal to the lighting lighting switching means! Since this device is equipped with a 2-wire electric aria, it has the advantage that the main illumination light and the auxiliary illumination light can be alternately switched by an indoor wall switch via a two-wire electric aria. .
