Description

The present invention relates to a luminaire control device that controls a luminaire. In particular, it relates to a device that controls a lighting fixture based on the presence or absence of a person.

Conventionally, a luminaire control device for controlling lighting, extinguishing, dimming, etc. of a luminaire using a pyroelectric sensor has been provided. The main components of the luminaire control device are a pyroelectric sensor, a control circuit and a power supply circuit. By controlling the luminaire with the luminaire control device, the state of the luminaire can be appropriately controlled according to the presence or absence of a person. For this reason, energy saving can be achieved, and it has been introduced in many houses and offices.

Here, the pyroelectric sensor has a plurality of pyroelectric elements. The pyroelectric sensor receives infrared rays radiated from a person or the like by a pyroelectric element. Pyroelectric elements that receive infrared rays cause spontaneous polarization and generate electromotive force. The control circuit monitors the voltage generated by the electromotive force generated by the pyroelectric sensor. Then, when the electromotive force is generated, it is determined that a person exists. Further, if no electromotive force is generated, it is determined that a person is absent. The control circuit controls lighting, extinguishing, and the like of the lighting equipment based on the determination of the presence or absence of a person.

Here, in the configuration of the luminaire control device, in order to improve the detection accuracy for the intrusion of a person, widen the infrared light input range and widen the detection range of the person, etc., the luminaire is based on a plurality of pyroelectric sensors. A controlled lighting system has been proposed (see, for example, Patent Document 1). This lighting system has a plurality of pyroelectric sensors having a plurality of pyroelectric elements, and by designating the arrangement of the plurality of pyroelectric sensors, it is possible to determine the presence or absence of a person with high accuracy.

However, when a plurality of pyroelectric sensors are used, the direction of the pyroelectric element of the pyroelectric sensor is adjusted, the detection accuracy is adjusted by processing the lens of the pyroelectric sensor, or a shielding plate is used between the pyroelectric sensors. It is necessary to process the structural surface of the device, such as adjusting the detection range. Further, in Patent Document 1, it is not possible to individually control the output signal from each pyroelectric sensor. Therefore, the setting related to the pyroelectric sensor related to the determination of the presence or absence of a person is determined by the arrangement of the pyroelectric sensor and the surrounding structure.

An object of the present invention is to provide a lighting fixture control device capable of making settings related to determination of the presence or absence of a person without performing complicated processing in terms of structure in order to solve such a problem. It is a thing.

The lighting fixture control device according to the present invention has an independent detection range, and individually processes a plurality of charcoal sensors that detect infrared rays and emit an output signal, and an output signal sent from each charcoal sensor. , A control circuit that determines the presence or absence of a person and controls the lighting equipment according to the set criteria, and a setting device that is connected to the control circuit and sets the input data related to the setting in the control circuit. The setting device is a receiving device that wirelessly receives a signal including data related to the setting sent from the outside and sends it to the control circuit, and the control circuit is a receiving device containing the data related to the setting obtained by receiving the signal. If it is determined that the data of the settings possessed is the same, the lighting fixture is notified that the settings will not be changed .

According to the present invention, the output signals sent from the plurality of pyroelectric sensors are individually processed according to the set determination criteria, so that the determination criteria are set according to the output signals of each pyroelectric sensor. By setting, it is possible to make settings related to determination of the presence or absence of a person, such as the detection range and detection accuracy of the pyroelectric sensor, without changing the structure of the lighting fixture control device.

Embodiment 1.
FIG. 1 is a diagram showing a configuration of a lighting system centered on a lighting fixture control device 100 according to the first embodiment of the present invention. The lighting system includes a lighting fixture 10 and a lighting fixture control device 100. The luminaire control device 100 includes a plurality of pyroelectric sensors 5, a control circuit 6, a setting device 7, and a power supply circuit 8.

The plurality of pyroelectric sensors 5 in the first embodiment are composed of a first pyroelectric sensor 1, a second pyroelectric sensor 2, a third pyroelectric sensor 3, and a fourth pyroelectric sensor 4. Here, when the first pyroelectric sensor 1, the second pyroelectric sensor 2, the third pyroelectric sensor 3 and the fourth pyroelectric sensor 4 are not specified in the plurality of pyroelectric sensors 5, the pyroelectric sensor 4 is focused. The electric sensors 1 to 4 will be described. Pyroelectric sensors 1 to 4 have a pyroelectric element. When infrared rays are input to the pyroelectric element, the pyroelectric sensors 1 to 4 spontaneously polarize and generate a voltage. The generated voltage is sent to the control circuit 6 as an output signal. The plurality of pyroelectric sensors 5 and the like will be described later.

The control circuit 6 determines the presence or absence of a person based on the output signals sent from the plurality of pyroelectric sensors 5, and performs a process of controlling the lighting fixture 10. Further, the setting device 7 is connected to the control circuit 6 and sends a signal regarding setting items input from the user to the control circuit 6. The setting items are data such as a threshold value and a set value set as a determination criterion for determining the presence or absence of a person based on the output signal from the pyroelectric sensor 5. The power supply circuit 8 supplies electric power to a plurality of pyroelectric sensors 5, the control circuit 6, and the setting device 7 in the luminaire control device 100.

FIG. 2 is a diagram illustrating a detection range in the plurality of pyroelectric sensors 5 according to the first embodiment of the present invention. As described above, the plurality of pyroelectric sensors 5 in the first embodiment are the first pyroelectric sensor 1, the second pyroelectric sensor 2, the third pyroelectric sensor 3, and the fourth pyroelectric sensor 4. It is composed. The first pyroelectric sensor 1, the second pyroelectric sensor 2, the third pyroelectric sensor 3, and the fourth pyroelectric sensor 4 each have an independent detection range. Here, the first pyroelectric sensor 1 can detect infrared rays in the detection range 12. Further, the second pyroelectric sensor 2 can detect infrared rays in the detection range 13. Further, the third pyroelectric sensor 3 can detect infrared rays in the detection range 14. Then, the fourth pyroelectric sensor 4 can detect infrared rays in the detection range 15. From the above, the infrared rays in the detection range 11 can be detected by the plurality of pyroelectric sensors 5 as a whole.

Further, since each pyroelectric sensor 1 to 4 has an independent detection range 12 to 15, the plurality of pyroelectric sensors 5 can detect infrared rays in a wide range as a whole. Here, the control circuit 6 can receive signals from the pyroelectric sensors 1 to 4, respectively. Therefore, the control circuit 6 can select a detection range from the detection range 11 and perform a determination process for determining whether or not a person exists. For example, the determination process is performed on the detection range 12 and the detection range 13, and the determination process is not performed on the detection range 14 and the detection range 15. The user can set the detection range in which the control circuit 6 performs the determination process via the setting device 7.

FIG. 3 is a diagram showing an example of the relationship between the pyroelectric sensor voltage 19 generated in the pyroelectric sensors 1 to 4 in the first embodiment of the present invention and the threshold value which is a condition set in the control circuit 6. The level of the generated voltage varies depending on the type and structure of the pyroelectric sensors 1 to 4. Here, the voltage generated by the pyroelectric sensors 1 to 4 is defined as the pyroelectric sensor voltage 19. For example, when the amount of infrared rays detected is large, the pyroelectric sensor voltage 19 becomes a high voltage signal as in the high voltage section 21. Further, when the amount of infrared rays detected is small, the pyroelectric sensor voltage 19 becomes a low voltage signal as in the low voltage section 22. Then, when infrared rays are not detected due to the absence of a person or the like, the pyroelectric sensor voltage 19 becomes a signal having a voltage as in the non-detection section 20.

In the luminaire control device 100 of the first embodiment, when the control circuit 6 performs the determination process, the threshold value to be compared with the signal of the pyroelectric sensor voltage 19 sent from the pyroelectric sensors 1 to 4 is set to the threshold value of the pyroelectric sensors 1 to 4. Corresponding to 4, it is set from one of three levels. Here, from the lowest level, the first threshold value 16, the second threshold value 17, and the third threshold value 18 are set. The user can set the threshold value via the setting device 7. For example, when the first threshold value 16 is set as the threshold value of the control circuit 6, the pyroelectric sensor voltage 19 in both the high voltage section 21 and the low voltage section 22 can be detected. Further, when the second threshold value 17 is set as the threshold value of the control circuit 6, the pyroelectric sensor voltage 19 in the high voltage section 21 can be detected. However, the pyroelectric sensor voltage 19 in the low voltage section 22 cannot be detected.

In this way, the user can set the threshold value used by the control circuit 6 for the determination process. The accuracy of detecting a person by the plurality of pyroelectric sensors 5 can be freely changed. Here, when the third threshold value 18 is set as the threshold value of the control circuit 6, the pyroelectric sensor voltage 19 in both the high voltage section 21 and the low voltage section 22 cannot be detected. Therefore, the function of determining the presence or absence of a person by the plurality of pyroelectric sensors 5 can be disabled. Further, by setting a threshold value for each signal of the pyroelectric sensor voltage 19 sent from the pyroelectric sensors 1 to 4, the user can detect the detection range other than the setting of whether or not to perform the determination process described above. Can be set via the setting device 7. Here, in the luminaire control device 100 of the first embodiment, it has been described that the threshold values of three levels can be set, but the present invention is not limited to this. The threshold value can be freely set regardless of the voltage level, the number, and the like.

For example, in the detection range 12 of the first pyroelectric sensor 1 shown in FIG. 2, when a person is present, the first pyroelectric sensor 1 detects infrared rays emitted by the person and is shown in FIG. The indicated pyroelectric sensor voltage 19 is sent to the control circuit 6 as a signal. When the control circuit 6 determines that the pyroelectric sensor voltage 19 of the signal sent from the first pyroelectric sensor 1 is higher than the set threshold value (for example, the first threshold value 16 in FIG. 3), the first It is determined that a person exists within the detection range 12 of the pyroelectric sensor 1. Then, the control circuit 6 controls, for example, to light the lighting fixture 10 brightly. When there is a person in the detection range 13 of the second pyroelectric sensor 2, when there is a person in the detection range 14 of the third pyroelectric sensor 3, there is a person in the detection range 15 of the fourth pyroelectric sensor 4. Even if it exists, the control circuit 6 performs the same control.

On the other hand, in the control circuit 6, there is no person in the detection range 11 of the plurality of pyroelectric sensors 5 in FIG. 2, or the pyroelectric sensor voltage 19 of the plurality of pyroelectric sensors 5 is set to a threshold value (for example, in FIG. 3). If it is determined that the threshold value is lower than the first threshold value 16), it is determined that no person exists in the detection range 11. Then, the control circuit 6 performs control such as turning off the lighting fixture 10. Therefore, if at least one of the pyroelectric sensor voltages 19 related to infrared detection of the plurality of pyroelectric sensors 5 is higher than the threshold value, it is determined that a person exists. Further, when the pyroelectric sensor voltage 19 related to all of the plurality of pyroelectric sensors 5 is lower than the threshold value, it is determined that a person is absent. This makes it possible to detect a person in a wide range.

As described above, according to the lighting fixture control device 100 of the first embodiment, the pyroelectric sensors 1 to 4 having independent detection ranges are installed, and the control circuit 6 sends the pyroelectric sensors 5 from the plurality of pyroelectric sensors 5. The output signals to be output are processed individually according to the set determination criteria. As a result, by setting the determination criteria according to the output signals of the pyroelectric sensors 1 to 4, the detection range and detection accuracy of the pyroelectric sensors 1 to 4 are not changed without changing the structure of the luminaire control device 100. For example, it is possible to make settings related to the determination of the presence or absence of a person.

Embodiment 2.
FIG. 4 is a diagram showing a configuration of a lighting system centered on a lighting fixture control device 100 according to a second embodiment of the present invention. In FIG. 4, with respect to the devices and the like having the same reference numerals as those in FIG. 1, the same operations as those described in the first embodiment are performed. The luminaire control device 100 according to the second embodiment includes a light receiving device 23 having a light receiving element 23A as the setting device 7 described in the first embodiment. The light receiving device 23 is a receiving device in which the light receiving element 23A receives an optical signal and converts the received optical signal into a signal that can be processed by the control circuit 6. In particular, in the second embodiment, the light receiving device 23 converts the optical signal sent from the remote setting device 24, which is an external device, and sends the signal to the control circuit 6. Here, the light receiving device 23 is a device that receives light, but may be a receiving device that receives a wireless signal such as another radio wave.

The remote setting device 24 is a device such as a remote controller that can perform wireless communication with the control circuit 6 of the lighting fixture control device 100 via the light receiving device 23. By inputting the settings to the remote setting device 24, the user can set the data of the determination criteria related to the determination of the presence or absence of a person, such as the detection range and the detection accuracy described in the first embodiment.

Here, it is assumed that the lighting fixture control device 100 of the second embodiment has a function of notifying the user of a response to a reception from the remote setting device 24. For example, the remote setting device 24 includes the data of the set value related to the user's setting in the optical signal and transmits the data. The light receiving device 23 sends a signal obtained by converting the optical signal received by the light receiving element 23A to the control circuit 6. The control circuit 6 controls the lighting fixture 10 to blink in order to notify the user that the signal has been received. Here, the number of blinks, the blinking time, the brightness, and the like of the lighting fixture 10 regarding the first blinking can be freely set. By blinking the lighting fixture 10 (first blinking), it is possible to notify the user that the setting has been changed.

Further, it is assumed that the lighting fixture control device 100 of the second embodiment has a function of notifying the user of the current set value. For example, the remote setting device 24 includes the data of the set value related to the user's setting in the optical signal and transmits the data. The light receiving device 23 sends a signal obtained by converting the received optical signal to the control circuit 6. The control circuit 6 determines whether or not the sent set value is the same as the currently set set value. When the control circuit 6 determines that the sent set value is the same as the currently set installation value, the lighting fixture 10 blinks (second blinking) to make it the current installation value and change the setting. Can be notified to the user that this has not been done. Here, the second blinking is set so that, for example, the number of blinks, the blinking time, the brightness, and the like of the lighting fixture 10 are different from those of the first blinking. Then, the number of blinks, the blinking time, the brightness, and the like of the lighting fixture 10 regarding the second blinking can be freely set.

Here, in the luminaire 10, the control circuit 6 does not accept the process based on the new optical signal while the first blinking and the second blinking are performed. Therefore, it is possible to prevent the notification from being confused, such as the first blinking and the second blinking being confused.

The power changeover switch 28 can individually switch the power supply to the pyroelectric sensors 1 to 4.

The user can freely set the sensor for supplying power among the pyroelectric sensors 1 to 4 via the setting device 7. Then, the control circuit 6 controls the switching of the power supply changeover switch 28 based on the setting.
