[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lighting device for controlling lighting of a lighting load based on a human body detection signal of a human sensor provided in a remote control transmitter.

[0002]

2. Description of the Related Art Conventionally, as shown in FIG. 16, a remote controller operating unit 13 for performing an on / off operation of a lighting load,
A transmission unit 14 that transmits a wireless signal formed of an optical signal such as infrared light to the outside, a remote control control unit 15 that transmits a control signal by a wireless signal from the transmission unit 14 based on an operation signal of the remote control operation unit 13, and each unit. A remote control transmitter 10 including a power supply unit 17 for supplying operating power, a receiving unit 21 for receiving a control signal transmitted by a wireless signal from the outside, and lighting of a lighting load 22 according to the control signal received by the receiving unit 21. There is provided a lighting device including a lighting device 20 including a lighting device control unit 23 that performs control such as turning off / off.

In such an illuminating device, when the remote control operating section 13 of the remote control transmitter 10 is operated to turn on or off the lighting load 22, a control signal is transmitted as a wireless signal from the transmitting section 14 of the remote control transmitter 10. To be done.
Then, the receiving unit 21 of the lighting fixture 20 has the remote control transmitter 1
Receive a control signal transmitted by wireless signal from 0,
The appliance control unit 23 according to the control signal received by the receiving unit 21.
Turned on or off the lighting load 22.

In this lighting device, the remote control transmitter 10 is used to go to the lighting load 2 without going to the place where the switch is installed.
3 can be turned on or off, but the remote control transmitter 10 is required for turning on / off, and especially when it is desired to turn on the lighting load 23 in a dark place, the remote control transmitter 10 can be used in dark surroundings. I had to search for, and was inconvenient.

Therefore, as shown in FIG. 17, a human sensor 11 for detecting the presence or absence of a person is used instead of the remote controller operating section 12.
Is provided in the remote control transmitter 10, and the remote control control unit 14 causes the transmission unit 13 to transmit a control signal by a wireless signal in response to a human body detection signal of the human sensor unit 11, and the lighting device 20
There is provided a lighting device in which the lighting load 23 is automatically turned on or off (Japanese Patent Laid-Open No. 10-32668).
No. 0 publication). In such an illuminating device, the remote control transmitter 10 is used by being fixed to a wall or the like in order to set the detection range of the motion sensor unit 11.

[0006]

In the former one of the above lighting devices, the user operates the remote control operating unit 12 at his own will.
Is operated to turn the lighting load 23 on or off, the lighting device 20 fails to receive the control signal transmitted from the remote control transmitter 10, and if the desired control is not performed, the user operates the remote control operating unit. 12 can be operated again, and the control signal can be transmitted from the remote control transmitter 10 by a wireless signal. However, in the latter lighting device, the remote control transmitter 10 transmits a wireless signal according to the detection signal of the motion sensor unit 11. Since the control signal is transmitted, the luminaire 20
Even if the wireless signal reception fails on the side, there is a problem that the wireless signal cannot be transmitted again from the remote control transmitter 10.

In the former lighting device, the user usually holds the remote control transmitter 10 in his hand and operates the remote control in the direction of the lighting device 20, but in the latter lighting device,
Since the remote control transmitter 10 is fixed to the wall, the wireless signal may not be directly transmitted to the lighting fixture 20 depending on the installation location, and it may be difficult to receive the wireless signal.

In order to solve such a problem, FIG.
As shown in, when the human sensor 11 of the remote control transmitter 10 outputs a human body detection signal at time t1, the remote control transmitter 10 sends the wireless signal A a plurality of times (for example, 3 times).
However, even if the wireless signal A is transmitted a plurality of times, it is not always possible for the lighting fixture 20 to receive the wireless signal A and the control signal A transmitted at time t1 is not always received. In the case of failure, the lighting load remains off until the control signal B is transmitted again at time t2.

As described above, since the lighting device automatically transmits the lighting signal in response to the input of the human body detection signal, even if the lighting signal cannot be received, the lighting device is turned on only at a preset timing. Since the signal is not sent and the lighting signal that failed to be received is not retransmitted, the lighting load remains off until the lighting signal is sent at the next timing, and the lighting load is turned on at the desired timing. I couldn't. Similarly, even when transmitting an extinguishing signal, if the extinguishing signal is unsuccessfully received, the extinguishing signal that has failed to be received is not retransmitted, so that there is a problem that the lighting fixture continues to be lit.

If there is not, the extinction signal transmitted last time is retransmitted from the transmission unit, and when the lighting fixture is extinguished, the ambient illuminance becomes the second
Since it becomes darker than the illuminance level of, the brightness detected by the illuminance sensor unit and the lightness and darkness of the second illuminance level are compared at the time when a predetermined time has passed since the turn-off signal was transmitted.
It is possible to reliably determine whether or not the turn-off signal has been properly received, and if the light does not become darker than the second illuminance level, the turn-off signal transmitted last time is retransmitted so that the lighting fixture can surely receive the turn-off signal. be able to.

(First Embodiment) A first embodiment of the present invention will be described with reference to FIGS. The lighting device of this embodiment includes a remote control transmitter 10 and a lighting device 20.

The remote control transmitter 10 comprises a human sensor 11 such as a pyroelectric element for detecting the presence or absence of a person in the detection area by detecting heat rays emitted from the human body, and CdS and a photodiode. A remote control operation unit that includes an illuminance sensor unit 12 that detects ambient brightness and a tact switch, a rotary switch, or a DIP switch, and that performs various settings of the lighting fixture 20 (for example, switching between lighting holding time and continuous lighting). 13 and a transmitter 1 for transmitting a wireless signal including an optical signal such as infrared light to the outside.
4 and a microcomputer, the human sensor unit 1
A remote controller control unit 15 for transmitting a control signal by a wireless signal from the transmission unit 14 based on the human body detection signal of No. 1 and the detection signal of the illuminance sensor unit 12, and a determination timer 16a,
A transmission mask timer 16b, a retrigger timer 16c,
A power supply unit 17 that supplies operating power to each unit. still,
In the present embodiment, the presence / absence of a person is detected by detecting a heat ray radiated from the human body using a pyroelectric element as the motion sensor unit 11, but it is possible to detect the presence / absence of the person by using an ultrasonic sensor or a distance measuring sensor. Presence or absence may be detected.

The luminaire 20 includes a receiver 21 for receiving a signal transmitted as a wireless signal from the outside and a lighting load 2.
2, a microcomputer, and an appliance control unit 23 for lighting, dimming or extinguishing the lighting load 22 according to a control signal received by the receiving unit 21, a lighting holding timer 24,
A power supply unit 25 that supplies operating power to each unit.

The count time of the retrigger timer 16c is set to be longer than the count time of the transmission mask timer 16b and shorter than the count time of the lighting hold timer 24.

The operation of this lighting device will be described below with reference to the time chart of FIG. In addition, each waveform in FIG. 2 is the detection value of the illuminance sensor unit 12 and the motion sensor unit 11 in order from the top.
Human body detection signal, count operation of transmission mask timer 16b, count operation of retrigger timer 16c, transmission unit 14
The transmission signal transmitted from, the counting operation of the lighting holding timer 24, and the lighting state of the lighting load 22 are shown.

When the retrigger timer 16c is not counting and the ambient brightness detected by the illuminance sensor unit 12 is darker than the first illuminance level L1, the human sensor unit 11 detects a person at time t1. Then, when the human body detection signal is output, the remote controller control unit 15 causes the transmission unit 14 to transmit the lighting signal S1 for lighting the lighting load 22, and the determination timer 16a and the transmission mask timer 16b.
Also, the count operation of the retrigger timer 16c is started. The illuminance level L1 is set to a predetermined level in advance by using the remote controller operation unit 13.

In the luminaire 20, when the receiver 21 receives the lighting signal S1 transmitted from the remote controller transmitter 10,
The appliance control unit 23 receives the lighting signal S1 received by the receiving unit 21.
The lighting load 22 is turned on according to the above. At the same time, the appliance control unit 23 causes the lighting holding timer 24 to start the counting operation of the lighting holding time, and when the counting operation of the lighting holding timer 24 ends, the lighting load 22 is turned off.

After the count operation of the transmission mask timer 16b is completed and the human sensor 11 outputs a human body detection signal during the count operation of the retrigger timer 16c, the remote controller control section 15 causes the remote controller controller 15 to count the count of the retrigger timer 16c. When the operation is completed (time t2, t3), the lighting continuation signal S2 for continuing the lighting state of the lighting load 22 is transmitted from the transmitting unit 14, and the counting operations of the transmission mask timer 16b and the retrigger timer 16c are started again. Let

When the receiver 21 of the lighting fixture 20 receives the lighting continuation signal S2 transmitted from the remote control transmitter 10, the fixture controller 23 holds the lighting according to the lighting continuation signal S2 received by the receiver 21. The counting operation of the timer 24 is reset and the lighting holding timer 24 is restarted from the beginning, and the lighting time of the lighting load 22 is extended.

On the other hand, after the end of the counting operation of the transmission mask timer 16b, and during the counting operation of the retrigger timer 16c, if there is no human body detection signal output from the human sensor unit 11, the remote controller control unit 15 causes the retrigger timer 1 to operate.
When the counting operation of 6c is completed (time t4), the lighting continuation signal is not transmitted.

Further, when the human body detection signal is input from the human sensor unit 11 during the counting operation of the transmission mask timer 16b, the remote controller control unit 15 ignores the human body detection signal, and the counting operation of the retrigger timer 16c ends. However, the continuous lighting signal is not transmitted.

By the way, the illuminance sensor section 12 of the remote control transmitter 10 always detects the ambient brightness, and the remote control control section 15 detects the illuminance sensor section at the time when a predetermined time has passed after the lighting signal S1 was transmitted. From the detection result of 12, it is determined whether or not the lighting signal is normally received on the side of the lighting device 20. 3A shows a time chart when the lighting device 20 successfully receives the lighting signal, and FIG. 3B shows a time chart when the lighting device 20 fails to receive the lighting signal. The waveforms of FIGS. 3 (a) and 3 (b) are, respectively, in order from the top, the detection value of the illuminance sensor unit 12, the human body detection signal of the human sensor unit 12, the transmission signal transmitted from the transmission unit 14, and the determination. The counting operation of the timer 16a is shown.

As described above, when the retrigger timer 16c is not counting and the ambient brightness detected by the illuminance sensor unit 12 is darker than the first illuminance level L1, the human sensor unit 11 detects the human body. When the signal is output, the remote controller control unit 15 causes the transmission unit 14 to transmit the lighting signal S1 at the time t11, and at the same time, the determination timer 16
If the detection result of the illuminance sensor unit 12 at the time t12 when the counting operation of a is started and the counting operation of the determination timer 16a ends as shown in FIG. 3A is brighter than the second illuminance level L2, It is determined that the lighting device 20 has successfully received the lighting signal and the lighting load 22 is lit,
The lighting signal S1 is not retransmitted. On the other hand, as shown in FIG. 3B, the detection result of the illuminance sensor unit 12 at the times t12 and t13 at which the counting operation of the determination timer 16a ends is the second.
If it is darker than the illuminance level L2, it is determined that the lighting fixture 20 has failed to receive the lighting signal S1 and the lighting load 22 remains unlit, and the lighting signal S1 transmitted last time is set as the retransmission signal S2 as the transmitting unit 14 And the counting operation of the determination timer 16a is restarted. Then, this operation is repeated until the detection result of the illuminance sensor unit 12 becomes brighter than the second illuminance level L2 (that is, until the lighting fixture 20 successfully receives the lighting signal and the lighting load 22 is lit). . The second illuminance level L2 is preset to a predetermined level which is brighter than the first illuminance level L1 and at least darker than the illuminance level when the appliance is turned on, by using the remote controller operating unit 13 as a setting means. Also,
The count value of the determination timer 16a and the number of times the lighting signal is retransmitted are also set to predetermined values in advance by the remote controller operating unit 13 which is a setting means.

By the way, in the present embodiment, the illuminance sensor section 12 of the remote control transmitter 10 constantly detects the ambient brightness, and the illuminance sensor is transmitted within a certain time after the lighting signal S1 is transmitted. The brightness detected by the unit 12 is the second
If it becomes brighter than the second illuminance level L2, it is determined that the lighting fixture 20 has received the lighting signal S1 and turned on the lighting load 22, and if it does not become brighter than the second illuminance level L2, the lighting fixture 20 lights up. It is determined that the lighting load 22 remains unlit due to the failure to receive S1, and the lighting signal is retransmitted.

As described above, in the present embodiment, it is determined whether or not the lighting device 20 can normally receive the lighting signal based on the detection result of the illuminance sensor unit 12, and if the lighting signal fails to be received, the lighting signal is received. Is transmitted again, it is possible to reliably transmit the lighting signal to the lighting fixture 20. Also,
Since the lighting signal is retransmitted only when the lighting signal is unsuccessfully received, the number of times the lighting signal is transmitted is reduced compared to the case where the lighting signal is transmitted multiple times regardless of whether or not the lighting signal is normally received. Since the power consumption of the remote control transmitter 10 is reduced, the battery life can be extended when the battery is used as the power source.

In this embodiment, the remote controller control unit 15
However, according to the human body detection signal from the human sensor 11, the transmitter 1
Although the lighting signal is transmitted from 4, the remote controller operation unit 1
The lighting signal may be transmitted according to the operation input of No. 3.

By the way, the lighting signal S1 on the lighting fixture 20 side
The reason why the remote control cannot be received may be noise due to the installation location of the remote control transmitter 10 and the lighting fixture 20 or the surrounding environment. Since the remote control transmitter 10 is equipped with the motion sensor section 11, it is not possible to unnecessarily change the installation location of the remote control transmitter 10 due to the detection area, and it is also difficult to change the surrounding environment. Therefore, the lighting signal S1
When retransmitting, the transmitting unit 14 may gradually increase the transmission output according to the number of times of retransmission, and even in an environment where there is noise, the lighting device 20 outputs the lighting signal by gradually increasing the transmission output. Can be easily received.

(Embodiment 2) FIG. 4 shows Embodiment 2 of the present invention.
~ It demonstrates with reference to FIG. In the present embodiment, in the first embodiment, the lighting holding timer 24 of the lighting fixture 20 is eliminated, and the remote control transmitter 10 is provided with the transmission mask timer 1.
A lighting holding timer 16d is provided instead of the 6b and the retrigger timer 16c. Since the basic configuration of the illuminating device is the same as that of the first embodiment, common components are denoted by the same reference numerals, and illustration and description thereof will be omitted, and only the characteristic features of the present embodiment will be described. .

Next, the operation of this illuminating device will be described with reference to the time chart of FIG. Note that the waveforms in FIG. 5 are, in order from the top, the detection value of the illuminance sensor unit 12, the human body detection signal of the human sensor unit 11, the counting operation of the lighting holding timer 16d,
The transmission signal transmitted from the transmitter 14 and the lighting state of the lighting load 22 are shown.

When the lighting holding timer 16d is not counting and the ambient brightness detected by the illuminance sensor section 12 is darker than the first illuminance level L1, the human sensor section 11 detects a person. When the human body detection signal is output by the remote controller controller 15, the transmitter 14 transmits a lighting signal for lighting the lighting load 22 at time t20.
Time t2 when there is no detection input from the human sensor unit 11.
At 1, the counting operation of the lighting holding timer 16d is started.

In the luminaire 20, when the receiving section 21 receives the lighting signal S1 transmitted from the remote control transmitter 10,
The appliance control unit 23 receives the lighting signal S1 received by the receiving unit 21.
The lighting load 22 is turned on according to the above.

Thereafter, if there is a detection input from the human sensor unit 11 during the counting operation of the lighting holding timer 16d (time t22, t24 in FIG. 5), the remote controller control unit 15 causes the lighting holding timer 16d to count. At the time of resetting, when there is no detection input from the human sensor unit 11 (time t
At 23, t25), the counting operation is restarted from the beginning. Then, when the counting operation of the lighting holding timer 16d ends (time t26), the remote controller control unit 15 transmits the turn-off signal S3 for turning off the lighting load 22 to the transmission unit 14.
To send from.

In the luminaire 20, when the receiving section 21 receives the extinguishing signal S3 transmitted from the remote control transmitter 10, the luminaire control section 23 responds to the extinguishing signal S3 received by the receiving section 21 to illuminate the load. 22 is turned off.

Here, the illuminance sensor section 12 always detects the ambient brightness, and the remote controller control section 15 is the same as in the first embodiment, at the time when a predetermined time has elapsed after the lighting signal S1 was transmitted. From the detection result of the illuminance sensor unit 12, it is determined whether or not the lighting signal S1 has been normally received on the lighting fixture 20 side. That is, the remote controller control unit 15
Starts the counting operation of the determination timer 16a at the same time as transmitting the lighting signal S1 from the transmission unit 14, and the detection result of the illuminance sensor unit 12 at the time when the counting operation of the determination timer 16a ends is the second illuminance. If it is brighter than the level L2, it is determined that the lighting fixture 20 has successfully received the lighting signal S1 and the lighting load 22 is lit, and the lighting signal S1 is not retransmitted. On the other hand, if the detection result of the illuminance sensor unit 12 at the time when the counting operation of the determination timer 16a is finished is darker than the second illuminance level L2, the lighting fixture 20 fails to receive the lighting signal S1, and the lighting load 22 is It is determined that the light remains off, and the lighting signal S transmitted last time
1 is transmitted from the transmitter 14 as a retransmission signal, and the counting operation of the determination timer 16a is restarted. Then, this operation is repeated until the detection result of the illuminance sensor unit 12 becomes brighter than the second illuminance level L2 (that is, until the lighting fixture 20 successfully receives the lighting signal and the lighting load 22 is lit). .

Further, in this embodiment, the remote controller control section 15
However, it is determined from the detection result of the illuminance sensor unit 12 at the time when a predetermined time has elapsed since the extinguishing signal S3 was transmitted, whether the extinguishing signal S3 was normally received on the lighting fixture 20 side. Here, FIG. 6A shows the turn-off signal S3 of the lighting device 20.
6 (b) is a time chart when the reception of the data is successful.
Shows respective time charts when reception of the extinguishing signal S3 fails. 6A and 6B, in order from the top, the detected value of the illuminance sensor unit 12, the human body detection signal of the human sensor unit 11, the counting operation of the lighting holding timer 16d, and the transmitting unit 14 are sequentially shown. From the transmission signal, the counting operation of the determination timer 16a, the lighting load 22
Shows the lighting state of each.

The remote controller control unit 15 controls the lighting holding timer 1
At the time when the counting operation of 6d is completed (time t31 in FIG. 6A), the light-off signal S3 is transmitted from the transmitting unit 14 and the counting operation of the determination timer 16a is started, and the counting operation of the determination timer 16a is started. The detection result of the illuminance sensor unit 12 at the time (time t32) when the
If it is darker than the illuminance level L2, it is determined that the lighting fixture 20 has successfully received the turn-off signal S3 and the lighting load 22 has been turned off, and the turn-off signal S3 is not retransmitted.

On the other hand, as shown in FIG. 6B, the detection result of the illuminance sensor section 12 at the time when the counting operation of the determination timer 16a is completed (time t32 in FIG. 6B) is based on the second illuminance level L2. If it is also bright, it is determined that the lighting fixture 20 has failed to receive the turn-off signal S3, and the lighting load 22 is still turned on, and the previously-transmitted turn-off signal S3 is retransmitted signal S.
4, and the counting operation of the determination timer 16a is restarted. Then, this operation is repeated until the detection result of the illuminance sensor unit 12 becomes darker than the second illuminance level L2 (that is, until the lighting fixture 20 successfully receives the turn-off signal and the lighting load 22 is turned off). .

As described above, in this embodiment, it is determined whether or not the lighting fixture 20 has successfully received the control signal (lighting signal and extinguishing signal) based on the detection result of the illuminance sensor section 12, and the control signal is received. If it fails, the control signal is transmitted again, so that the control signal can be reliably transmitted to the lighting fixture 20. In addition, since the control signal is retransmitted only when the control signal is unsuccessfully received, the control signal is transmitted as compared with the case where the control signal is transmitted multiple times regardless of whether the control signal is normally received. Since the number of times is reduced and the power consumption of the remote control transmitter 10 is reduced, the battery life can be extended when the battery is used as the power source.

In this embodiment, the remote controller control unit 15
However, according to the human body detection signal from the human sensor 11, the transmitter 1
Although the lighting signal is transmitted from 4, the remote controller operation unit 1

Changes the count time of the determination timer 6a according to the control content of the lighting signal. Since the configuration of the lighting device is the same as that of the second embodiment, the description thereof will be omitted and only the characteristic features of the present embodiment will be described.

The human body detection signal of 1, the transmission signal transmitted from the transmission unit 14, the counting operation of the lighting holding timer 16d, and the counting operation of the determination timer 16a are shown.

In this embodiment, as shown in FIGS. 7 (a) and 7 (b), the fixture control section 23 of the lighting fixture 20 has a fade-in control in which the lamp output is gradually brightened when the lamp is turned on, and a lamp output is gradually increased when the lamp is turned off. If fade-out control is performed to make the lamp darker and the rise time (fade-in time) and the fall time (fade-out time) of the lamp output are different for each lighting fixture 20, the fade-in control or fade-out control ends. The remote controller control unit 15 is provided so that reception judgment can be performed while the lamp output is stable.
Changes the count time of the determination timer 16a according to the control content. For example, as shown in FIG.
When the fade-in time or the fade-out time is longer than that in the case of FIG. 7A, the count value of the determination timer 6a at the time of lighting and at the time of turning off is set to a long time, and the fade-in control is performed. It is possible to prevent an erroneous determination because the reception determination is performed while the or fade-out control is being performed.

Further, in the case of the lighting signal, since a person exists within the detection area of the motion sensor section 11, that is, within the lighting area of the lighting load 22, it is desirable to turn on the lighting load 22 as soon as possible. Therefore, it is desirable to shorten the count time of the determination timer 6a. On the other hand, in the case of the turn-off signal, since the person is not in the lighting area, the timing of turning off the lighting load 22 may be delayed. Therefore, the remote controller control unit 15 sets the count time when determining the reception of the lighting signal to a shorter time than the count time of the determination timer 6a when determining the reception of the turn-off signal. It is possible to promptly judge whether or not the reception is normally performed and retransmit the data, and it is possible to prevent the timing of lighting from being delayed.

Furthermore, the remote controller control unit 15 may change the count time of the determination timer 16a in accordance with the time zone of the day, so that it can be quickly turned on or turned off quickly. Sets the count time of the determination timer 16a to a time shorter than other time zones, thereby promptly determining whether or not the lighting signal and the extinguishing signal are normally received and retransmitting them. It is possible to prevent the timing of turning on or off from being delayed.

Further, in the present embodiment, the setting value of the judgment timer 16a is changed in the lighting device of the second embodiment, but in the lighting device of the first embodiment, the setting value of the judgment timer 16a is changed similarly to the above. However, it goes without saying that it is good.

(Embodiment 4) FIG. 8 shows Embodiment 4 of the present invention.
~ It demonstrates with reference to FIG. In the second embodiment, the value of the second illuminance level L2 is a constant value, whereas in the present embodiment, the value of the second illuminance level L2 is changed according to the control content. Since the configuration of the lighting device is the same as that of the second embodiment, the description thereof will be omitted and only the characteristic features of the present embodiment will be described.

In the second embodiment, since the value of the second illuminance level L2 is a constant value, the value of the second illuminance level L2 used for reception determination when transmitting the lighting signal S1 and the extinguishing signal S3 are transmitted. At this time, the value of the second illuminance level L2 used for reception determination is the same value, but in the present embodiment, when it is determined whether or not the reception of the lighting signal S1 is normal, as shown in FIG. Changes the value of the second illuminance level L2 from the ambient illuminance at the time of turning off to a bright value L2a of about several hundred Lx. Further, when determining whether or not the reception of the turn-off signal S3 is normal, the ambient illuminance at the time of turn-off differs depending on other light sources and the illuminance situation of the surroundings.
The value of 2 is switched from the ambient illuminance at the time of lighting to a value L2b which is dark, for example, about several hundred Lx. Note that each waveform in FIG. 8 is, in order from the top, the detection value of the illuminance sensor unit 12, the human body detection signal of the human sensor unit 11, the transmission signal transmitted from the transmission unit 14, the counting operation of the lighting holding timer 16d, and the illumination. Load 2
The two lighting states are shown respectively.

Here, when the lighting signal S1 is transmitted, the remote control controller 15 detects the brightness detected by the illuminance sensor 12 and the second illuminance level when the count time of the determination timer 16a has elapsed since the signal was transmitted. The lightness and darkness of L2a are compared. Since the second illuminance level L2a is set to a value that is several hundred Lx brighter than the ambient illuminance when the light is off,
If the lighting load 22 is turned on, the brightness at that time is surely brighter than the second illuminance level L2a. Therefore, if the brightness at the time when the counting operation of the determination timer 16a is finished is brighter than the second illuminance level L2a, it is surely determined that the lighting signal S1 is normally received and the lighting load 22 is lit. Therefore, the lighting signal S1 is not retransmitted.

When the turn-off signal S3 is transmitted, the remote control controller 15 detects the brightness detected by the illuminance sensor 12 and the second illuminance level L2b when the count time of the determination timer 16a has elapsed since the signal was transmitted. Is comparing the light and dark. Since the second illuminance level L2b is set to a value that is a few hundred Lx darker than the ambient illuminance at the time of lighting, if the lighting load 22 is off, the brightness at that time is surely higher than the second illuminance level L2b. Also gets dark. Therefore,
If the brightness at the time when the counting operation of the determination timer 16a is finished is darker than the second illuminance level L2b,
It can be reliably determined that the lighting load 22 has been extinguished by normally receiving the extinguishing signal S3, and the extinguishing signal S3 is not retransmitted.

By the way, in the present embodiment, the value of the second illuminance level L2 is changed according to the control content, but the value of the second illuminance level L2 is changed according to the time zone of the day. You may do it. For example, in a time period when it is desired to turn on or off the lighting load 22 with certainty, the value of the second illuminance level L2 used for reception determination at the time of transmitting the lighting signal S1 is set to a brighter value than other time periods, and the turn-off signal S3 If the value of the second illuminance level L2 used for the determination at the time of transmission is set to a darker value than in the normal time, the lighting signal S1 and the extinguishing signal S3 are easily retransmitted, and the lighting signal S1 or the extinguishing signal S
By making it easier to retransmit 3, it is possible to reliably turn on or off the light.

Further, when the illuminance level at the time of lighting differs depending on the time zone of the day, for example, as shown in FIG. 9, in the normal time zone (time zone other than midnight such as daytime), the lighting load 2
2 is lit at a lighting level of 100%, while the lighting load 22 is lit at a lighting level of 50% in the middle of the night, the set value of the second illuminance level is set to The value L2c, which is darker than the normally set value L2a, may be set in the midnight time zone. In addition, each waveform in FIG. 9 is, in order from the top, the lamp output in the normal time zone, the lamp output in the midnight time zone, the detection value of the illuminance sensor section 12, and the motion sensor section 1.
1 shows the human body detection signal, the transmission signal transmitted from the transmission unit 14, the counting operation of the lighting holding timer 16d, the counting operation of the determination timer 16a in the normal time zone, and the counting operation of the determination timer 16a in the midnight time zone. ing.

In such a case, it may be possible to set the second illuminance level to L2c from the beginning, but the illuminance level when the light is turned off changes depending on the surrounding environment, so the second illuminance level is set to be low. Then, there is a possibility that it may be erroneously determined that the lighting load 22 is turned on even though the lighting load 22 is turned off. Therefore, it is desirable to set the value of the second illuminance level to a value that can be surely determined to be turned on. Therefore, by setting the setting value of the second illuminance level to be lower in the midnight time period than in the normal time period, it can be reliably determined whether or not the lighting load 22 is turned on. In addition, since it is considered that the lighting fixtures installed in the surroundings are also turned off in the midnight time,
There is no particular problem even if the illuminance level is set low.

By the way, in the present embodiment, only the value of the second illuminance level L2 is changed according to the control contents and the time zone, but the value of the second illuminance level L2 is changed, and in the third embodiment. As described above, the count time of the determination timer 16a may be changed.

For example, as shown in FIG. 10, in a normal time zone, when determining whether or not the reception of the lighting signal S1 is normal, the value of the second illuminance level L2 is calculated from the ambient illuminance at the time of extinguishing by, for example, a number. The value of the second illuminance level L2 is switched from the ambient illuminance at the time of lighting to a dark value L2b of about several hundred Lx, for example, when determining whether the reception of the extinguishment signal S3 is normal while switching to a bright value L2a of about 100 Lx. Further, since the fade-out time is longer than the fade-in time, the determination timer 16a at the time of transmitting the lighting signal S1
The counting time of the determination timer 16a at the time of transmitting the extinguishing signal S3 is set to be longer than the counting time of, and is set to be slightly longer than the fade-in time and the fade-out time, respectively. Also, the lighting load is 2 in the midnight hours.
Since the lighting level of No. 2 is darker than that in the normal time zone, the value of the second determination level L2 is set to a value L2c that is darker than the value at the normal time. Note that each waveform in FIG. 10 is output from the lamp output in the normal time zone, the lamp output in the midnight time zone, the detection value of the illuminance sensor section 12, the human body detection signal of the human sensor section 11, and the transmission section 14 in order from the top in the order from the top. The transmission signal to be transmitted, the counting operation of the lighting holding timer 16d, the counting operation of the determination timer 16a in the normal time zone, and the counting operation of the determination timer 16a in the midnight time zone are shown.

Further, the value of the second illuminance level L2 may be set by the user himself / herself by using the remote controller operation unit 13, or the value of the illuminance level L2 used for the determination at the time of transmitting the lighting signal S1, The value of the illuminance level L2 used for determination at the time of transmitting the turn-off signal S3 may be set in advance, and the set value may be switched between when the lighting signal S1 is transmitted and when the turn-off signal S3 is transmitted.

Further, in the present embodiment, the setting value of the second illuminance level L2 is changed in the illuminating device of the second embodiment. However, in the illuminating device of the first embodiment, the setting value of the second illuminance level L2 is changed as described above. It goes without saying that the set value may be changed.

(Fifth Embodiment) FIG. 1 shows a fifth embodiment of the present invention.
1 and FIG. 12 will be described. In the first embodiment, when the lighting device 20 fails to receive the lighting signal S1, the number of times of resending the lighting signal S1 is limited to within a predetermined number of times. However, in the present embodiment, the remote control transmitter 10 uses the retransmission timer. 16e is provided, and the counting operation of the retransmission timer 16e is started when the lighting signal S1 is transmitted.
The lighting signal S1 is retransmitted until the counting operation of 6e is completed. Since the configuration other than the retransmission timer 16e is the same as that of the first embodiment, the common components are denoted by the same reference numerals, and illustration and description thereof are omitted, and only the characteristic features of the present embodiment will be described.

The operation of this lighting device will be described below with reference to the time chart of FIG. 12 are transmitted from the detection value of the illuminance sensor unit 12, the human body detection signal of the human sensor unit 12, the counting operation of the transmission mask timer 16b, the counting operation of the retrigger timer 16c, and the transmission unit 14 in order from the top. Transmission signal, the counting operation of the determination timer 16a, and the counting operation of the retransmission timer 16e.

When the retrigger timer 16c is not performing the counting operation and the ambient brightness detected by the illuminance sensor section 12 is darker than the first illuminance level L1, the human sensor section 11 detects a person and detects the human body. When the detection signal is output, the remote controller control unit 15 causes the transmitter 14 to transmit the lighting signal S1 for lighting the lighting load 22 at the time t41, and the determination timer 16a and the transmission mask timer 1
6b, the retrigger timer 16c, and the retransmission timer 16e start counting operations.

Here, the illuminance sensor unit 12 always detects the ambient brightness, and the remote control unit 15 controls the illuminance sensor unit 12 at the end of counting by the determination timer 16a.
If the detection result of is darker than the second illuminance level L2, it is determined that the lighting device 20 has failed to receive the lighting signal S1,
The previously transmitted lighting signal S1 is transmitted as the retransmission signal S2 from the transmission unit 14, and the determination operation of the determination timer 16a is started. If the detection result of the illuminance sensor unit 12 does not become brighter than the second illuminance level L2 despite the transmission of the retransmission signal S2, it is determined that the reception of the retransmission signal S2 has also failed, and the retransmission timer 16e The above operation is repeated until the counting operation of is completed.

The count time of the retransmission timer 16e is set to be approximately the same as the count time of the lighting holding timer 24, and the count operation of the retransmission timer 16e is continued even after the count operation of the retrigger timer 16c is completed at time t43. The retransmission signal S2 can be transmitted until the time t44 when it ends. When the human sensor 11 outputs the human body detection signal after the count operation of the transmission mask timer 16b ends and during the count operation of the retrigger timer 16c, the remote controller control unit 15 causes the retrigger timer 16 to operate.
When the counting operation of c is completed (time t42), a lighting signal is transmitted from the transmitting unit 14 to continue the lighting state of the lighting load 22, and the transmission mask timer 1
6b and the retrigger timer 16c are restarted, the retransmission timer 16e is reset, and the counting operation is restarted from the beginning.

(Embodiment 6) FIG. 1 shows Embodiment 6 of the present invention.
3 and FIG. 14 will be described. In the second embodiment, when the lighting device 20 fails to receive the lighting signal S1 or the extinguishing signal S3, the number of times of resending the lighting signal S1 or the extinguishing signal S3 is limited to within a predetermined number of times. Then, the remote control transmitter 10 has a retransmission timer 1 for a lighting signal.
6e and a retransmission timer 16f for the extinguishing signal are provided, and the retransmission timer 16 is provided when the lighting signal S1 or the extinguishing signal S3 is transmitted.
The counting operations of e and 16f are started,
The lighting signal S1 or the extinguishing signal S3 is retransmitted until the counting operations of the retransmission timers 16e and 16f are completed.
The configuration other than the retransmission timers 16e and 16f is the same as the second embodiment.
Therefore, the same reference numerals are given to the common configurations, the illustration and description thereof are omitted, and only the characteristic portions of the present embodiment will be described.

The operation of this lighting device will be described below with reference to the time chart of FIG. 14 are transmitted from the detected value of the illuminance sensor unit 12, the human body detection signal of the motion sensor unit 12, the counting operation of the transmission mask timer 16b, the counting operation of the retrigger timer 16c, and the transmission unit 14 in order from the top. Transmission signal, the counting operation of the determination timer 16a, the counting operation of the retransmission timer 16e, and the counting operation of the retransmission timer 16f.

When the retrigger timer 16c is not counting and the ambient brightness detected by the illuminance sensor unit 12 is darker than the first illuminance level L1, the human sensor unit 11 detects a person and detects the human body. When the detection signal is output, the remote controller control unit 15 causes the transmission unit 14 to transmit a lighting signal for lighting the lighting load 22 at time t51, and the determination timer 16a and the transmission mask timer 16
b, retrigger timer 16c and retransmission timers 16e, 16
The counting operation of f is started.

When the human sensor 11 outputs a human body detection signal during the counting operation of the retrigger timer 16c after the end of the counting operation of the transmission mask timer 16b, the remote controller control section 15 causes the remote controller controller 15 to count the retrigger timer 16c. When the operation is completed (time t53), the lighting continuation signal S2 for continuing the lighting state of the lighting load 22.
The transmission mask timer 16b, the retrigger timer 16c, and the retransmission timer 16e.
The counting operation of is restarted.

Here, also in this embodiment, the first embodiment
Similarly, the remote controller control unit 15 determines whether or not the lighting signal S1 is successfully received based on the detection value of the illuminance sensor unit 12, and the illuminance sensor unit at the time when the counting operation of the determination timer 16a ends. If the detection result of 12 is darker than the second illuminance level L2, the lighting device 20 outputs the lighting signal S1.
It is determined that the lighting load 22 is still turned off, the lighting signal S1 transmitted last time is transmitted from the transmission unit 14 as the retransmission signal S2, and the determination timer 1
The counting operation of 6a is restarted. Then, while the retransmission timer 16e is counting, the detection result of the illuminance sensor unit 12 becomes brighter than the second illuminance level L2 (that is, the luminaire 20 successfully receives the lighting signal and the lighting load 22).
Until is lit), repeat this operation.

When the human sensor unit 11 stops outputting the human body detection signal, the lighting hold timer (not shown) and the retransmission timer 16f provided in the remote control transmitter 10 start counting operation. The count time of the lighting hold timer and the count time of the retransmission timer 16f are set to be substantially the same time, and the lighting hold timer performs substantially the same operation as the retransmission timer 16f.

After that, the lighting holding timer and the retransmission timer 1
When a human body detection signal is input during the counting operation of 6f,
The remote controller control unit 15 resets the counting operation of the lighting holding timer and the resending timer 16f, and when the human body detection signal is no longer input, the lighting holding timer and the resending timer 1
The counting operation of 6f is restarted from the beginning.

When the counting operation of the lighting holding timer ends at time t54, the remote controller control unit 15
Resets the counting operation of the retransmission timer 16e, stops the transmission of the lighting signal S1 and its retransmission signal S2 from the transmitter 14, and starts the transmission of the extinguishment signal S3.

Here, as in the case of the lighting signal, the remote controller control section 15 judges whether or not the extinction signal S3 has been successfully received based on the detection value of the illuminance sensor section 12, and the judgment timer 16a counts. If the detection result of the illuminance sensor unit 12 at the time of ending the operation is brighter than the second illuminance level L2, the lighting fixture 20 fails to receive the turn-off signal S1,
It is determined that the lighting load 22 is still turned on, the extinction signal S3 transmitted last time is transmitted from the transmission unit 14 as the retransmission signal S4, and the counting operation of the determination timer 16a is restarted. Then, while the retransmission timer 16f is counting, until the detection result of the illuminance sensor unit 12 becomes darker than the second illuminance level L2 (that is, the lighting fixture 20 successfully receives the turn-off signal and the lighting load 22 is turned off. Until), repeat this operation.

As described above, in this embodiment, the lighting fixture 20 is used.
If the side fails to receive the lighting signal S1 or the extinguishing signal S3, until the resending timer 16e for the lighting signal or the resending timer 16f for the extinguishing signal finishes the counting operation,
Since the lighting signal S1 or the extinguishing signal S3 is continuously transmitted at a predetermined time interval, the lighting load 22 can be reliably turned on or off.

(Embodiment 7) FIG. 1 shows Embodiment 7 of the present invention.
This will be described with reference to the time charts 5 (a) and 5 (b).
Since the configuration of the illuminating device is the same as that of the first embodiment, common components are denoted by the same reference numerals, and illustration and description thereof are omitted, and only the characteristic features of the present embodiment will be described.

Each waveform in FIG. 15A is, in order from the top, the detected value of the illuminance sensor section 12, the human body detection signal of the human sensor section 12, the counting operation of the transmission mask timer 16b, the counting operation of the retrigger timer 16c, and the transmission. The transmission signal transmitted from the unit 14, the counting operation of the determination timer 16a, the counting operation of the retransmission timer 16e, and the counting operation of the retransmission timer 16f are shown. Further, FIG. 15B shows the operation of the luminaire 20, and the respective waveforms are, in order from the top, the counting operation of the lighting holding timer 20 when the lighting signal transmitted for the first time is received, and the lighting load at that time. 22 lighting state, counting operation of the lighting holding timer 20 when receiving the lighting signal transmitted for the third time, lighting state of the lighting load 22 at that time, lighting holding when the lighting signal transmitted for the third time is received The counting operation of the lighting holding timer 20 when the time is corrected and the lighting state of the lighting load 22 at that time are respectively shown.

In the first embodiment, as shown in FIGS. 15 (a) and 15 (b), the luminaire 20 fails to receive the transmission signal S1 transmitted at time t61, and then the retransmission signal transmitted at time t62. When S2 is received, the lighting holding timer 20 starts counting operation of a predetermined lighting holding time from the time t62 when the retransmission signal S2 is received, and the lighting load 22 is turned on for the predetermined lighting holding time. Compared to the case where the transmitted lighting signal S1 is normally received, the timing at which the lighting load 22 is turned off is delayed from t63 to t64. However, between time t63 and t64, it is considered that there are no people in the illumination area, so it is useless to turn on the illumination load 22 during this time, and it is preferable to turn off the illumination load as soon as possible.

Therefore, in the present embodiment, the remote control transmitter 1
When the retransmission signal S2 is transmitted from 0 to the lighting fixture 20, the data of the number of retransmissions is transmitted together with the retransmission signal S2,
In the luminaire 20, the receiving unit 21 receives the retransmission signal S2 and the data of the number of times of retransmission, and based on the number of times of retransmission, the elapsed time from the time when the lighting signal S1 is first transmitted is obtained, and the lighting holding time is calculated. Lighting load only for the time obtained by subtracting the elapsed time 22
Is lit.

For example, the time interval at which the retransmission signal S2 is transmitted, that is, the count time of the determination timer 16a is 1 second,
Assuming that the lighting holding time is 30 seconds and the lighting signal transmitted for the third time can be received, 2
The lighting load 22 is turned on for 7 seconds (= 30 (seconds) -1 (seconds) × 3 (times)), and the same timing as when the lighting signal S1 transmitted for the first time is normally received. The lighting load 22 can be turned off with.

[0086]

As described above, according to the first aspect of the present invention, a human sensor for detecting the presence or absence of a person, an illuminance sensor for detecting ambient brightness, and a control signal transmitted to the outside by a wireless signal. When the human body sensor outputs the human body detection signal in a state where the brightness detected by the transmitter and the illuminance sensor is darker than the first illuminance level, the transmitter outputs a lighting signal for lighting the lighting load in a desired lighting state. A remote control transmitter having a remote control control unit for transmitting from an external device, a receiving unit for receiving a lighting signal transmitted by a wireless signal from the outside, and a device control for controlling lighting of a lighting load based on the lighting signal received by the receiving unit. The remote controller control unit is configured such that the brightness detected by the illuminance sensor unit is brighter than the first illuminance level when a predetermined time elapses after the lighting signal is transmitted. In addition, at least when the lighting level does not become brighter than the second illuminance level set to be darker than the lighting level when the lighting device is turned on, the lighting signal transmitted last time is retransmitted from the transmitting unit, and the lighting device sends the lighting signal. When the illumination load is received and the lighting load is turned on, the brightness detected by the illuminance sensor unit becomes brighter than the second illuminance level. Therefore, the illuminance sensor unit at the time when a predetermined time has elapsed after the lighting signal was transmitted. By comparing the detected brightness and the lightness and darkness of the second illuminance level, it can be surely determined whether or not the lighting signal is normally received, and if it is not brighter than the second illuminance level, it is transmitted last time. Since the lighting signal is retransmitted, there is an effect that the lighting device can surely receive the lighting signal.

According to a second aspect of the present invention, in the first aspect of the present invention, the remote controller control unit, when a certain time elapses after the human body detection signal is not output from the human sensor unit after the lighting signal is transmitted, An extinguishing signal for extinguishing the lighting load is transmitted from the transmitting unit, and at a time point when the predetermined time has elapsed after transmitting the extinguishing signal, if the brightness detected by the illuminance sensor unit is darker than the second illuminance level. If it is not, the previously transmitted extinguishing signal is retransmitted from the transmitting unit. When the lighting fixture is extinguished, the ambient illuminance becomes darker than the second illuminance level, so a predetermined time has elapsed since the extinguishing signal was transmitted. By comparing the brightness detected by the illuminance sensor unit and the lightness and darkness of the second illuminance level at that time, it is possible to reliably determine whether or not the turn-off signal is normally received.
When it does not become darker than the illuminance level of 1, the retransmitting of the extinguishing signal transmitted last time has an effect that the lighting device can surely receive the extinguishing signal.

According to a third aspect of the present invention, in the first aspect of the present invention, there is provided setting means for setting the predetermined time and the second illuminance level to desired values, and the setting means sets the predetermined time. And, there is an effect that the second illuminance level can be set to a desired value.

According to a fourth aspect of the present invention, in the first aspect of the present invention, the second illuminance level is provided with a means for changing the second illuminance level according to the control content of the lighting signal. There is an effect that can be changed according to the control content of the lighting signal.

According to a fifth aspect of the present invention, in the first aspect of the present invention, there is provided means for changing the predetermined time according to the control content of the lighting signal, and the predetermined time is the control content of the lighting signal. There is an effect that it can be changed according to.

The invention of claim 6 is characterized in that, in the invention of claim 1, means for changing the predetermined time and the second illuminance level according to a time zone of a day is provided. There is an effect that the predetermined time and the second illuminance level can be changed according to the time of day.

According to a seventh aspect of the invention, in the invention according to any one of the first to sixth aspects, a predetermined lighting holding time is counted after a lighting signal is first transmitted to the remote control transmitter. If the brightness provided by the illuminance sensor unit is not brighter than the second illuminance level by providing a timer, the remote controller control unit performs an operation of retransmitting the lighting signal from the transmission unit until the count operation of the timer ends. It is characterized in that it is repeated a plurality of times, and by retransmitting the lighting signal a plurality of times, there is an effect that the lighting device can surely receive the lighting signal.

According to an eighth aspect of the present invention, in the invention according to any one of the first to seventh aspects, the brightness detected by the illuminance sensor section of the remote controller is brighter than the second illuminance level. Up to this point, the operation of retransmitting the lighting signal from the transmitter is repeated a plurality of times, and the transmitter is characterized by increasing the transmission output as the number of retransmissions increases.By increasing the transmission output as the number of retransmissions increases, The effect is that the lighting signal can be easily received on the device side.

According to a ninth aspect of the present invention, in the invention according to any one of the first to third aspects, the remote controller control unit controls the brightness detected by the illuminance sensor unit to be higher than the second illuminance level. Until the light becomes bright, the operation of retransmitting the lighting signal from the transmitting unit is repeated multiple times at predetermined time intervals, and when the lighting signal is transmitted, the information on the number of times of retransmission is transmitted together with the lighting signal. When the lighting control signal and the information on the number of retransmissions are received, the appliance control unit uses the information on the number of retransmissions received by the reception unit to obtain the elapsed time from the time when the lighting signal is first transmitted, and the predetermined lighting holding time. Lighting control of the lighting load is performed for a period of time obtained by subtracting the elapsed time from, and when the lighting signal transmitted first fails to be received and the lighting signal transmitted thereafter is received, the time And light up by Luo predetermined lighting holding time, but the timing of the lighting load is turned off as compared with the case where the normally received the first transmitted light-up signal is delayed,
The remote control transmitter transmits information on the number of retransmissions to the lighting equipment together with the lighting signal, and the equipment control unit, based on the information on the number of retransmissions, calculates the elapsed time from the time when the lighting signal is first transmitted, Since the lighting is performed for the time obtained by subtracting the elapsed time from the lighting holding time, there is an effect that the lighting load can be turned off at the same timing as when the first transmitted lighting time is normally received.
