Description

  The present invention relates to a lighting fixture and a lighting control system capable of performing lighting and / or dimming control of a lighting unit.

  As a method of performing the lighting and / or dimming control of the lighting fixture by recognizing the presence or absence of the user, the fixture side is generally provided by providing a human sensor such as a heat ray sensor. Conventionally, two methods have been used in which the user actively detects the presence using a remote controller.

  For example, in Patent Literature 1, when a person is detected by a human sensor of a certain lighting fixture, infrared rays are transmitted from a transmission unit, and other received lighting fixtures also turn on lighting means. A lighting control system that does not require address setting and wiring work has been proposed.

  Patent Document 2 proposes an illumination control system in which an illuminance sensor and a human sensor are provided on a remote controller so that human sensors need not be provided on a plurality of lighting fixtures.

Furthermore, in Patent Document 3, when both the remote controller and the luminaire have a transmission / reception function and a channel confirmation code is transmitted from the remote controller side, the luminaire returns the channel setting value of the receiver, and the remote controller side There has been proposed a lighting device with a remote controller that has a function of setting a reception channel without providing a setting switch by displaying a control signal with the channel setting value.
Japanese Patent No. 3433608 JP-A-8-31576 Japanese Patent Laid-Open No. 7-122368

  In each of the above-described conventional techniques, it is possible to recognize the presence or absence of a user and perform lighting and / or dimming control of a lighting fixture. However, in the method in which the appliance side performs active detection using the human sensor, even if a certain delay time can be set, if the user's movement is lost, the presence of the user cannot be confirmed and the light is turned off. End up. For this reason, there is a problem that it cannot be used for detecting users with little movement such as desk work, which can only be used for purposes such as corridors through which users pass and security lights. .

  On the other hand, in the method in which the user actively notifies the presence using the remote controller, the user needs to control voluntarily, so there is a problem that the user cannot forget to turn it off and cannot be controlled appropriately. In addition, since the entire floor or a part of the blocks are controlled by the remote controller, it is difficult to control a narrow range such as only near the user. Even if the combination changes, there is also a problem that it is difficult to recombine the system once it is installed.

  Furthermore, in any conventional technique, the control mode is uniform regardless of the user. Specifically, for example, when it is detected by the human sensor that the user has gone out of the detection range, the light is turned off after a predetermined delay time has elapsed. Therefore, even if a user belonging to the room leaves the room temporarily and returns immediately, the lighting equipment is turned off and must be turned on again. There is a problem that it takes a burden. On the other hand, when an outside person temporarily enters or passes through the room, it remains lit for a certain period of time after leaving, even though the possibility of returning again is small. In such a case, there is a problem that energy saving is not sufficient.

  An object of the present invention is to provide a lighting apparatus capable of appropriately lighting and / or dimming a relatively narrow range in the vicinity of the user without any movement of the user and without being aware of the user. And providing a lighting control system.

  The luminaire of the present invention is mounted on the luminaire or is provided with a reception control means provided in the vicinity of the luminaire, and is portable and has an identification for periodically performing wireless communication with the reception control means at a predetermined period. The reception control means turns on and / or adjusts the illumination means in response to the identification information of the identification device registered in advance during the period of communication with the identification device. It is characterized by light control.

  According to the above configuration, when performing the lighting and / or dimming control of the luminaire automatically by recognizing the presence or absence of the user, the reception control means is provided in or near the luminaire and this reception is performed. The identification device carried by the user, such as in response to a search signal from the control means, periodically performs radio communication with the reception control means, and the reception control means communicates with the identification device. During the period, the lighting means is turned on and / or dimmed. The lighting and / or dimming control may be only control of lighting / extinguishing, or may be performed until the brightness is controlled (dimming) by recognizing the distance or the like, or used in a constantly lit state. When a person is present, it indicates that only dimming control such as increasing the brightness may be performed.

  Then, the control content is switched to a preset mode in association with the identification information received from the identification device. For example, if the identification information represents a person belonging to the room, there is a high possibility that it will return again even if the identification information is not received. When it is possible to reduce the burden on the lighting equipment by preventing blinking, or to realize a comfortable (easy to enter) environment for the user, and conversely, when the identification information represents an outsider Since the possibility of returning again is low when the business is completed due to temporary entry or passage, etc., when the identification information is no longer received, it is immediately turned off to promote energy saving.

  Therefore, since the lighting and / or dimming control is performed using a signal that is activated from the user side without the user being aware of it, the user can be aware of this even without any movement of the user. The presence or absence of the user can be recognized by the lighting apparatus, and a relatively narrow range near the user can be appropriately turned on and / or dimmed. Further, more appropriate lighting and / or dimming control can be performed according to the type of the recognized user.

  In the lighting apparatus of the present invention, the identification device includes a first storage unit that stores identification information unique to the identification device, and a first reception unit that receives a search signal from the reception control unit. And a first transmission means for transmitting a search reply signal including identification information stored in the first storage means when the search signal is received by the first reception means. The reception control means includes an ID card, and the reception control means receives a search return signal from a second transmission means for periodically transmitting a search signal at the predetermined cycle and an identification device responding to the search signal. Receiving means, identification information of an identification device that permits lighting and / or dimming control of the illumination means, and second storage means that stores control contents corresponding to the identification information, and the second reception The search return by means When a signal is received, the identification information of the received search reply signal is compared with the identification information stored in the second storage means, and if they match, the illumination means is turned on with the corresponding control content. And / or illumination control means for dimming control.

  According to the above configuration, the identification can be performed when the lighting device can recognize the presence or absence of the user without the user's movement as described above and without being aware of the user. The search is performed by a first storage unit storing identification information unique to the identification device, a first reception unit receiving a search signal from the reception control unit, and the first reception unit. When the signal is received, the search reply signal including the identification information stored in the first storage means is generated and transmitted, and preferably, the first transmission means for generating power for reply is provided, An ID card using a so-called wireless tag short-range wireless communication technology, and correspondingly, the reception control means includes a second transmission means for periodically transmitting a search signal at the predetermined period, and the search signal. From the responding identification device Second receiving means for receiving the search reply signal; second information for storing identification information of an identification device that permits lighting and / or dimming control of the lighting means; and control contents corresponding to the identification information. When the search reply signal is received by the storage means and the second receiving means, the identification information of the received search reply signal is compared with the identification information stored in the second storage means, and they match. In this case, the lighting means includes lighting control means for lighting and / or dimming control with the corresponding control contents.

  Therefore, even if there is no movement of the user as described above and without the user being aware of it, the lighting device recognizes the presence of the user and the lighting means corresponding to the recognized user. A configuration capable of performing lighting and / or dimming control can be specifically realized.

  Furthermore, the lighting apparatus of the present invention includes a human sensor that senses a person. When the presence sensor detects the presence of a user, the lighting control unit turns on and / or adjusts the lighting unit. It is characterized by performing light control.

  According to the above configuration, when the presence of a user is detected by the sensor by further combining a human sensor that senses a person with infrared rays or the like, the lighting control means turns on the lighting means and / or Alternatively, dimming control is performed.

  Therefore, even when a user who does not carry the identification device approaches, lighting control can be automatically performed in the same manner as in the conventional configuration. As a result, it is possible to perform appropriate control without causing the user carrying the identification device to be aware of it without impairing the convenience of the user who does not carry the identification device. .

  In the lighting apparatus of the present invention, the reception control unit further includes a setting unit, and when the setting mode is set, the setting unit stores the identification information received by the second receiving unit in the second storage unit. It is characterized by memorizing it.

  According to the above configuration, the reception control means is provided with setting means so that it can be switched to the setting mode by, for example, operating a setting switch provided in a lighting fixture or transmitting a setting mode signal from the identification device. In the setting mode, the setting means stores the identification information received by the second receiving means in the second storage means. At this time, by receiving and storing the identification information of many identification devices in groups, it becomes possible to control the mode corresponding to each group.

  Therefore, the reception control means side receives all the search signals, collects the identification devices at positions where the returned search reply signals are received without error by the second reception means, and enters the setting mode. Since the identification information of the identification devices is sequentially registered in the second storage means, the registration work of the identification information is easy. Thereafter, the registered identification device may be distributed to each user.

  Furthermore, in the luminaire of the present invention, the reception control means further includes an inter-apparatus communication means for exchanging the received identification information and a control signal representing the control content in response to the other luminaire, The illumination control unit performs lighting and / or dimming control on the illumination unit in response to a control signal obtained by the inter-apparatus communication unit.

  According to the above configuration, since there is little possibility that the reception control means of all the lighting fixtures can communicate with the identification device carried by the user, the lighting fixtures receive the search reply signal and When the control content is determined, a control signal is transmitted to the other lighting fixtures together with the received identification information, and the lighting and / or dimming control is performed. The inter-appliance communication means is realized by short-range wireless communication means, power line communication means, or the like.

  Therefore, even without providing means for overseeing control of the entire lighting fixture, among the distributed lighting fixtures, lighting and / or dimming can be appropriately performed in cooperation with the lighting fixture that has received the identification information. Control can be performed.

  Moreover, the lighting control system of the present invention comprises a plurality of the above-mentioned lighting fixtures.

  According to the above configuration, using the inter-apparatus communication means, it is possible to appropriately light and / or adjust a relatively narrow range near the user as described above in cooperation with another lighting apparatus. An illumination control system capable of light control can be realized.

  As described above, the lighting fixture of the present invention recognizes the presence or absence of a user and automatically performs lighting control and / or dimming control of the lighting fixture. The identification device carried by the user periodically communicates with the reception control means by responding to the search signal from the reception control means, and the reception control means During the period of communication with the apparatus, the lighting unit is turned on and / or dimmed according to the type of user.

  Therefore, since the lighting and / or dimming control is performed using a signal activated from the user side before the user is conscious, even if there is no movement of the user and without the user being conscious, The presence or absence of the user can be recognized on the side of the lighting fixture, and a relatively narrow range near the user can be appropriately turned on and / or dimmed. Further, more appropriate lighting and / or dimming control can be performed according to the type of the recognized user.

  Moreover, the illumination control system of this invention is provided with two or more said illumination fixtures provided with the inter-apparatus communication means as mentioned above.

  Therefore, using the inter-appliance communication means, the autonomous decentralized network is constructed in cooperation with other lighting equipment, and a relatively narrow range near the user as described above is appropriately It is possible to realize an illumination control system capable of controlling lighting and / or dimming.

[Embodiment 1]
FIG. 1 is a block diagram showing an electrical configuration of a lighting control system according to an embodiment of the present invention. In general, the lighting control system includes a plurality of lighting fixtures L1, L2,... (Generally referred to as reference symbol L hereinafter) connected to each other by a communication path 1, and the lighting fixture L is The lighting and dimming control is performed by communicating with the ID card 2 which is an identification device. Each luminaire L is supplied with power by a power line (not shown). Each luminaire L is configured to perform lighting control on the illuminating means 3 such as a discharge lamp or a lamp and to include an illumination control device 4 which is a reception control means.

  The ID card 2 is carried by a user and is composed of, for example, a name tag-like ID card having an appearance as shown in FIG. 2, and is configured as shown in FIG. That is, a storage unit 11 composed of a nonvolatile memory such as FlashROM and its peripheral circuit, a processing unit 12 composed of a microcomputer and its peripheral circuit, and wireless communication technology of a wireless tag of 13.56 MHz or 13.75 MHz, for example. It comprises a transmission unit 14 and a radio wave reception unit 15 configured using the

  On the other hand, each said lighting fixture L has an external appearance shape as shown, for example in FIG. 4, and the said illumination control apparatus 4 is comprised as shown in FIG. That is, a storage unit 21 composed of a nonvolatile memory such as FlashROM and its peripheral circuits, a processing unit 22 composed of a microcomputer and its peripheral circuits and the like, which reads and executes a program stored in the storage unit 21; An illumination control unit 23 that can control lighting / extinguishing of the illumination means 3 and can change luminance; a transmission unit 24 and a radio wave reception unit 25 configured by using a wireless communication technology of the wireless tag; Human communication comprising a communication unit 27 configured to use power line communication, near field communication technology such as Bluetooth (registered trademark), etc., and to communicate with other lighting devices via the communication path 1, and a heat ray sensor And a sensor 28.

  When the presence of a person is detected in response to the output from the human sensor 28, the processing unit 22, which is an illumination control unit, controls lighting of the illumination unit 3 via the illumination control unit 23. In addition, the processing unit 22 is a transmission that is a second transmission unit toward the ID card 2 at a predetermined cycle according to a program or table stored in the storage unit 21 as will be described later. A search signal to be described later is transmitted from the unit 24. In response to this, when the search reply signal from the ID card 2 is received at a strength equal to or higher than a predetermined threshold in the radio wave receiving unit 25 as the second receiving means, the processing unit 22 identifies the identification information in the search reply signal. (Hereinafter referred to as “ID”) is compared with the ID that should allow the lighting control of the lighting unit 3 stored in the storage unit 21 serving as the second storage unit. The lighting means 3 is turned on and / or dimmed in a manner registered in advance in association with the ID. Furthermore, the processing unit 22 communicates with other lighting devices in the vicinity through the communication unit 27 that is an inter-apparatus communication means, and is linked to the other lighting devices in the vicinity so as to be described later. The lighting and / or dimming control of the means 3 is performed. In this way, without providing means for controlling the entire lighting fixture L, the lighting fixture L that is closest to the ID card 2 among the distributed lighting fixtures L, and therefore the lighting fixture closest to the user, is mainly used. An autonomous decentralized lighting control system that can perform lighting and / or dimming control not only directly above but also in the vicinity has been constructed.

  When the processing unit 12 of the ID card 2 receives the search signal from the illumination control device 4 by the radio wave receiving unit 15 that is the first receiving unit, the processing unit 12 stores the search signal in the storage unit 11 that is the first storing unit. The self ID is read out, and the search reply signal including the ID is returned to the lighting control device 4 from the transmission unit 14 as the first transmission means.

  The ID card 2 uses the wireless tag technology, is not equipped with a power supply, receives the search signal from the illumination control device 4, obtains an electromotive force at the radio wave receiving unit 15, and sends it to each unit. Although it supplies, you may make it mount a power supply. The means used for identifying the user is not limited to the ID card, and any means may be used as long as the received electric field intensity on the lighting fixture L side is weak and the user can be recognized nearby. For example, unlike public lines, such as PHS (Personal Handyphone System) terminals and PDA (Personal Data Assistant) terminals used in factories, many users use common identification information. It is desirable that each time the number of users increases, there is no need to write the ID stored in the storage unit 21 on the lighting fixture L side, and there is no need for complicated identification processing, which is carried by the user. Things are desirable.

  In the lighting fixture L, the transmission unit 24 and the radio wave receiving unit 25 may not be provided integrally with the lighting fixture L, and may be provided separately in the vicinity. Moreover, the illumination means 3 and the illumination control apparatus 4 may be isolate | separated. From the point of view of ensuring communication quality with the ID card 2 and the design, it is not necessary for the lighting fixture L to be integrated with the entire structure, and the search reply signal from the ID card 2 is received. It is only necessary that the radio wave receiving unit 25 to be provided is provided in the vicinity of the paired lighting fixtures L.

  Below, the outline | summary of the operation | movement in this Embodiment is demonstrated.

  First, the processing unit 22 serving as the illumination control means detects the distance from the lighting fixture L to the user using at least the output from the radio wave receiving unit 25 serving as the second receiving means, and is within a predetermined distance. For example, the lighting means 3 is controlled to be turned on and dimmed. The distance is detected by a time difference from when the search signal is transmitted from the transmission unit 24 as second transmission means until the search reply signal is received by the radio wave reception unit 25 and / or the radio wave reception unit 25. It can obtain | require from the received electric field strength level etc. of the said search reply signal obtained by (1).

  The mode of the dimming control is such that the lighting device L is fully lit when it is at a position relatively close to the user, and the brightness is reduced when it is at a relatively far position. As a result, it is possible to perform fine dimming control according to the distance between the luminaire L and the user, such as promoting energy saving while ensuring the illuminance near the user.

  Further, the lighting control mode is generally detected by receiving the search reply signal by the human sensor 28 or the radio wave receiving unit 25 when the user enters the control range to be turned on. Although lighting starts, after that, even if there is no movement of the user, the lighting is continued at least while the search reply signal is received by the radio wave receiving unit 25, and when the search reply signal is not received, The light is turned on for a time corresponding to the ID of the search reply signal and then turned off. Specifically, when the received ID represents a stationary user belonging to the room, there is a high possibility that the ID will return again even if the ID is not received. For example, by setting to 5 minutes, frequent blinking is prevented to reduce the burden on the lighting fixture L side, or a comfortable (easy to enter) environment for the user is realized, and conversely, the ID is outside the outside. In the case of representing a non-stationary user such as a person, since it is unlikely that the user will return again after completing a request for temporary entry or passage, when the ID is not received, In the case of a person who is turned off in a short time, for example 1 minute, and does not carry the ID card, it is set in advance in association with the ID so that it is turned off in a shorter time, for example 30 seconds, and energy saving is promoted. In the aspect that Is that changing.

  In addition, the processing unit 22 controls the IDs received by the respective lighting fixtures L and the control contents to be performed in correspondence with the other lighting fixtures in the vicinity via the communication unit 27 that is an inter-appliance communication unit. When the own device is the closest to the user from the information on the received electric field strength obtained by exchanging signals, the own device becomes the main device, and the control signal is transmitted to the other lighting devices in the vicinity through the communication unit 27. A dimming instruction signal is transmitted to perform dimming control. Otherwise, it becomes a slave and performs dimming control in response to the dimming instruction signal given through the communication unit 27. . Therefore, although there is little possibility that the transmission unit 24 and the radio wave reception unit 25 of all the lighting fixtures L can communicate with the ID card 2 carried by the user, as described above, the entire illumination is performed. Without providing a means for controlling the control of the appliance L, it is possible to construct an autonomous decentralized network with the illumination fixture closest to the user among the distributed fixtures L and receive the ID. The lighting control can be appropriately performed in cooperation with the lighting fixtures.

  Furthermore, the communication unit 27, which is an inter-appliance communication means, exchanges data (broadcast transmission) with the luminaires L of the entire system, such as the received electric field strength of the search reply signal from each luminaire L. The dimming instruction signal communicates between adjacent lighting fixtures. For this reason, the distance table between each lighting fixture L is stored in the memory | storage part 21, and when the own machine is the closest to a user, the light control instruction | indication signal containing the distance information of the lighting fixture of the range which should be controlled is displayed. Then, the light is transmitted from the front and rear lighting fixtures in order to the final lighting fixture. Therefore, when the dimming instruction signal is received as a follower as described above, the distance between the source of the dimming instruction signal and the own apparatus is read with reference to the distance table, and the read result is transmitted. If the result is not 0, the subtracted distance information is transmitted to the next lighting fixture. By repeating such pipeline operation, it is suitable for lighting control in a relatively narrow range, reducing the traffic between the lighting fixtures L and reducing the possibility of signal collision, and communication. Light control can be performed within a specified control range from the main unit while simplifying measures for preventing the collision such as finely defining a protocol. Moreover, the data capacity required for the memory | storage part 21 of each lighting fixture L can be decreased. If there is no problem in traffic due to a small number of fixtures, the main lighting fixture may directly control the lighting fixtures up to the final stage.

  Further, as described above, when the processing unit 22 determines that the own device is within the control range and is not the last-stage lighting device from the dimming instruction signal transmitted thereto, the processing unit 22 proceeds to the next-stage lighting device. The dimming instruction signal is transmitted. However, if the lighting fixture in the next stage is out of lamp or has failed, and there is no response to the dimming instruction signal, the own machine becomes the substitute main machine. In addition, a substitute control instruction signal, which is a kind of the control signal, is broadcasted simultaneously to other lighting fixtures toward the other lighting fixtures, and the control range is expanded, so that the lamp burnout or fixtures are increased. Compensation for malfunctions such as malfunctions is also provided by other lighting fixtures.

  Below, each operation | movement mentioned above is explained in full detail. First, it is assumed that the lighting fixtures L having the shape shown in FIG. 4 are arranged in a matrix of 3 rows × 3 columns as shown in FIG. Table 1 shows the contents of the distance table stored in the storage unit 21 when the intervals between the rows and the columns are, for example, equal intervals of 2 m.

  Table 1 shows an example in which, when each luminaire L is the main engine, the luminaires to be directly controlled (control target range) are those that are immediately adjacent to each other (distance between fixtures up to 2 m). Therefore, in the case of 3 rows × 3 columns shown in FIG. 6, the lighting fixture L5 at the center position with the largest number of units to be controlled is L2, L4, L6, and L8. Table 2 shows an example of the control content when the brightness of the illumination control range is controlled in steps in accordance with the distance from the main unit.

  In the example of Table 2, if the lighting control range is, for example, 6 m, the main machine lights up 100%, the main machine lights up to 4 m (that is, 2 m, 4 m), 70% lights up, and the main machine lights up 30% at 6 m, Beyond that, it goes out. However, if there is an instruction for proxy control from the upstream (parent) side of the failed device due to the failure of the device, and the failed device is within the control target range of its own machine, 100% The substitute lights up.

  7-17 is a figure which shows the blinking state of each lighting fixture L for demonstrating the above-mentioned operation | movement further in detail. Here, for simplification of description, only the blinking state is shown, but actually, as shown in Table 2, the dimming control is performed according to the higher level among the obtained dimming level data. . In the fixture arrangement shown in FIG. 6, it is assumed that the lighting fixtures L1 to L3 are arranged linearly in the hallway 51, and the remaining lighting fixtures L4 to L9 are arranged in the office 52 in 2 rows × 3 columns. It shall be. The entrance / exit 53 to the office 52 is provided in the center of the office 52, and the entrance / exit 53 faces the lighting fixture L5 on the office 52 side and the lighting fixture L2 on the corridor 51 side. In order to make the explanation easy to understand, the elapsed time and the control time are illustrated, but it goes without saying that it is an example.

  First, FIGS. 7 to 12 are stationary users of the present lighting control system, and a user carrying an ID card whose ID belongs to the office 52 is in the vicinity of the lighting fixture L9. It is a figure which shows the blinking state at the time of passing the corridor 51 from the entrance / exit 53, and removing a seat temporarily. This path is indicated by reference numeral 54. In general, the human sensor 28 detects a change in the temperature distribution within the detection range, and notifies the processing unit 22 that the person has moved within the detection range when the change amount is a certain amount or more. Notification is performed when a person enters the detection range and when a person leaves the detection range. When a person enters the detection range, the processing unit 22 turns on the lighting unit 3 of the own machine. In FIG. 7, the human sensor 28 of the luminaire L9 finally detects a user who has entered the route indicated by the reference numeral 54 in the reverse direction, has not moved for a predetermined time, and is in a non-detected state. And

  On the other hand, when the search response signal is received by the radio wave control unit 25 in response to the search signal from the transmission unit 24, the processing unit 22 determines whether the ID of the received ID card is a steady user. And the time at the time of the control start is also memorize | stored in the ID table during control of the memory | storage part 21, and lighting control is started. In the example of FIG. 7, the user is close to the lighting fixture L9, and the search reply signal is received by the lighting fixtures L6, L8, and L9. In this case, the luminaire L9 has the highest received electric field strength, and the luminaires L6 and L8 are received at an electric field strength that is medium or slightly above the threshold that can be determined to be received, or the luminaire L9 alone exceeds the threshold. , Will receive. The remaining lighting fixtures L1 to L5 and L7 do not have the received electric field intensity exceeding the threshold value.

  Accordingly, the lighting fixture L9 first turns on its own device in response to the output from the human sensor 28, and then communicates the received ID and received electric field strength with other lighting fixtures through the communication unit 27. It is determined that the machine is a master, and the dimming instruction signals are transmitted to the lighting fixtures L6 and L8 within the control target range in the distance table of Table 1 to be turned on, and the state shown in FIG. 7 is obtained. After that, when a search return signal is received for each stored ID under control at regular time intervals and no response is received and a person leaves the detection range of the human sensor 28 (final control), The time is stored in the storage unit 21, and the processing unit 22 calculates the elapsed time from that time, and performs the extinction control at a time corresponding to each ID as shown below.

  In the state where the user C1 is seated (still), the ID card search process and the in-control ID table update process are performed at regular intervals. However, since the ID card is almost stationary, as a result, each lighting device L The blinking state is maintained in the initial state shown in FIG.

  When the user C1 moves along the route indicated by the reference mark 54 and the ID card search signal transmission timing arrives at the timing of passing through the vicinity of the lighting fixture L6 after 10 seconds, the lighting fixture L6 is the next master. Lighting control is implemented. As a result, as shown in FIG. 8, the lighting fixtures L3 and L5 are newly turned on, and the lighting fixture L9 is controlled by the lighting fixture L6, and the ID table update process during the control is performed and the lighting fixtures are continuously turned on. However, the lighting fixture L8 that has been controlled by the lighting fixture L9 has passed 10 seconds with the previous search timing as the final control timing. However, in the present embodiment, since the user C1 is a stationary user as described above, 10 seconds of the elapsed time is within 5 minutes of the delay time of the stationary user, and the lighting fixture L8 remains on. Become.

  After 10 seconds, the user C1 reaches the doorway 53 as shown in FIG. 9, and when the ID card search signal transmission timing arrives at the timing of passing through the vicinity of the lighting fixture L5, the lighting fixture L5 becomes the master next time. Lighting control is implemented. As a result, the luminaire L2 is newly lit, and the luminaires L6 and L8 are controlled by the luminaire L5, and the ID table updating process is performed during the control, and the luminaire L2 is continuously lit, but is controlled by the luminaire L6. Although the lighting fixtures L3 and L9 that have been used have passed 10 seconds with the previous search timing as the final control timing, they remain lit.

  After 10 seconds, the user C1 reaches the exit of the hallway 51 as shown in FIG. 10, and when the ID card search signal transmission timing arrives at the timing of passing the vicinity of the lighting fixture L1, the lighting fixture L1 is next Lighting control is performed as a master. As a result, the luminaire L4 is newly lit, and the luminaire L2 is controlled by the luminaire L1, and the ID table updating process is performed during the control, and the luminaire L5 and the luminaire are lit continuously. The lighting fixtures L6 and L8 that have been controlled by L5 remain on after 10 seconds have passed with the previous search timing as the final control timing. Further, since the ID card search signal transmission timing has not arrived when the user C1 passes nearby, the lighting fixture L2 does not become a master, and the lighting fixture L3 and the lighting fixture L9 require 20 seconds from the final control. Although it has passed, it remains lit.

  Therefore, the lighting state when one minute has passed since the user C1 started moving is as shown in FIG. 11, and as a result, the remaining lighting fixture L7 that has been away from the user C1 all the time is left. The lighting fixtures L1 to L6, L8, and L9 are lit in the order described above. For example, after 3 minutes, when the user C1 returns by following the path of FIG. 7 at this time, the lighting state remains as shown in FIG. 11 because it is still within the delay time from the final control time. As a result, new lighting control does not occur, and it is possible to extend the lamp life by reducing the burden on the lighting fixtures, or to realize an environment in which the user can easily enter the office 52. When the delay time of 5 minutes elapses from the final control time point, the lights are turned off in that order, and the light is completely turned off in FIG.

  Next, FIGS. 13 and 14 and FIG. 12 described above do not belong to the office 52, which is a non-stationary user of this lighting control system, but are in-house persons who carry an ID card with ID C2. FIG. 6 is a diagram showing a blinking state when passing through the hallway 51 along a route indicated by reference numeral 55. When the user C2 is detected by the lighting fixture L3 at the entrance of the hallway 51, the lighting fixture L3 serves as a master to perform lighting control. As a result, as shown in FIG. 13, the lighting fixtures L2 and L6 are turned on.

  After 10 seconds, when the ID card search signal transmission timing arrives at the timing of passing the vicinity of the lighting fixture L2, the lighting fixture L2 becomes the master next and lighting control is performed, and the lighting fixtures L1 and L5 are newly turned on. In addition, the lighting fixture L3 is controlled by the lighting fixture L2, the ID table update process during the control is performed, and the lighting fixture L6 is continuously turned on. However, the lighting fixture L6 controlled by the lighting fixture L3 has the previous search timing. 10 seconds have passed as the final control timing, and the light remains on. After 10 seconds, the user C2 reaches the exit of the hallway 51 as shown in FIG. 14, and when the ID card search signal transmission timing arrives at the timing of passing through the vicinity of the lighting fixture L1, the lighting fixture L1 is next Lighting control is performed as a master. As a result, the lighting fixture L4 is newly turned on, and the lighting fixture L2 is controlled by the lighting fixture L1, and the ID table updating process during the control is performed and is continuously turned on, but the lighting fixture L2 is controlled by the lighting fixture L2. The lighting fixtures L3 and L5 that have been used remain on after 10 seconds have elapsed with the previous search timing as the final control timing. Further, the lighting fixture L6 also remains lit after 20 seconds from the final control. Thereafter, the lights are turned off in the order in which 1 minute of the delay time has passed, which is shorter than that of the stationary user C1, and the light is completely turned off in FIG. Thus, further energy saving can be achieved.

  Subsequently, FIGS. 15 to 17 and FIG. 12 described above are routes in which an outside user C3 who does not carry an ID card who is a non-stationary user of the present lighting control system shows the corridor 51 with the reference numeral 55. It is a figure which shows the blinking state when passing by. When the user C3 is detected by the human sensor 28 of the lighting fixture L3 at the entrance of the corridor 51, the lighting fixture L3 serves as a master to perform lighting control. As a result, as shown in FIG. 15, the lighting fixtures L2 and L6 are turned on. This state is the same as in FIG.

  After 10 seconds, when passing through the vicinity of the lighting fixture L2, it is detected again by the human sensor 28. Next, the lighting fixture L2 is used as a master to perform lighting control, and the lighting fixtures L1 and L5 are newly lit. The previous lighting fixtures L3 and L6 are no longer controlled, and 10 seconds have passed with the previous detection timing as the final control timing, and the lighting fixtures remain lit. After another 10 seconds, the user C3 reaches the exit of the hallway 51 as shown in FIG. 16, and is detected by the human sensor 28 by passing through the vicinity of the lighting fixture L1, and next, the lighting fixture L1 is the master. Thus, the lighting fixture L4 is newly lit, but the previous lighting fixtures L2 and L5 are no longer controlled, and 10 seconds have passed since the previous detection timing is the final control timing, and the lighting fixture L4 remains lit. At this time, the lighting fixtures L3 and L6 also remain lit although 20 seconds have passed since the final control timing.

  When more than 10 seconds elapse, the delay time of the user C3 is 30 seconds shorter than the users C1 and C2, so that the lighting fixtures L3 and L6 are turned off as shown in FIG. In L5, ten or more seconds have elapsed from the final control timing and remain lit, and the lighting fixtures L1 and L4 have also been lit in several seconds from the final control timing. After that, when nearly 30 seconds elapse, all the lights are turned off as shown in FIG. Thus, further energy saving can be achieved.

  18 to 28 are flowcharts for explaining the above-described operation in more detail. Hereinafter, the operation in the present embodiment will be described in detail with reference to these drawings.

  First, FIG. 18 illustrates the overall control operation of the luminaire L by the processing unit 22. In step S1, the radio wave receiving unit 25 directly receives a search reply signal from the ID card 2 and receives a new direct reception whose ID is that of a new ID card that has not been received at the previous reception timing. It is determined whether or not it is an ID, and when the search reply signal is not received, and when the search reply signal is received from the ID card that has been received, the process proceeds to step S01. In step S01, it is determined whether or not a human motion equal to or greater than the threshold has been detected by the human sensor 28. If not detected, the process proceeds to step S2.

  In step S2, it is determined whether or not there is a control end target ID as will be described later in the IDs that are currently under dimming control. If not, the process proceeds to step S3, where the communication unit 27 receives from other lighting fixtures. It is determined whether or not a signal has been received. If not, the process moves to step S4. In step S4, it is determined whether or not the transmission timing of the search signal having a predetermined period from the transmission unit 24 is reached. If not, that is, if there is no change, the process proceeds to step S02, and the ID table in control is further controlled. It is determined whether or not the update timing has come, and if it is not the update timing, the process returns to step S1 to repeat the above-described processing and wait until some change occurs.

  When the search signal transmission timing comes in step S4, the process proceeds to the search process of the ID card 2 shown in FIG. 19 in step S5. First, in step S11, a search signal is transmitted, and in step S12, it is determined whether or not a search reply signal is received. If not received, in step S13, the search reply signal is transmitted from the preset transmission of the search signal. It is determined whether or not the waiting time has been completed. If the waiting time has not elapsed, the process returns to step S12 to continue waiting for the search reply signal.

  On the other hand, when the search reply signal is received in step S12, the process proceeds to step S14, and the ID in the search reply signal stores the ID currently under dimming control stored in the storage unit 21. It is determined whether or not it is included in the in-control ID table. If it is not included, it is stored in the storage unit 21 in step S15 as the new direct reception ID, and the process proceeds to step S13. When the ID in the received search reply signal is included in the in-control ID table in step S14, the process proceeds to step S16, and is stored in association with the ID in the in-control ID table. It is determined whether or not the received electric field strength of the search reply signal received this time has changed by a predetermined value or more with respect to the received electric field strength (measured by the radio wave receiving unit 25) (user) Is moved), the process proceeds to step S15, and after the ID is updated and stored in the storage unit 21 as the new direct reception ID, the waiting time determination of step S13 is performed, If the value has not changed more than the specified value (the user has not moved), the ID is not updated, and the process proceeds directly to the waiting time determination in step S13.

  In step S13, when the specified waiting time is over, the process proceeds to step S17, and an ID that is neither the new direct reception ID nor the continuous control target ID described later is set as the control end target ID from the in-control ID table. Then, the search process for the ID card 2 ends.

  On the other hand, if there is a new direct reception ID in step S1, the process proceeds to step S6, and master determination processing is performed for determining whether the own device should become the master device (master) or the slave device (slave). The result of the determination is determined in step S7, and if it is the own machine or the master, the active illumination control process is performed in step S8, and the process returns to step S1, and if it is the slave, the process returns directly to step S1.

  FIG. 20 is a flowchart for explaining in detail the master determination process in step S6. The following processing is performed for each new direct reception ID stored in step S14 or S16 to step S15. In step S21, a predetermined unit time is waited. In step S22, it is determined whether or not a received electric field strength notification signal from another lighting fixture has been received. If not, in step S23, the received electric field strength is handled. It is determined whether or not the (proportional) waiting time has elapsed. If not, the process returns to step S21. In the received electric field strength notification signal, the ID of the transmission source (the luminaire that has received the search reply signal) and the ID of the ID card that has transmitted the search reply signal received by the luminaire, the luminaire and the user, At least information indicating the received electric field strength, which is information indicating the distance. The standby time is set shorter as the electric field strength at the time of reception is higher. Therefore, during this standby time, a reception electric field strength notification signal is received from another lighting fixture, that is, a lighting fixture whose reception electric field strength is higher than that of the own device and whose standby time has ended earlier. After waiting, in step S24, as will be described later, a reception electric field strength confirmation process is performed between the luminaires that have received the search reply signal from the same ID card, and the process is terminated.

  When the received electric field strength notification signal is received from another lighting fixture in step S22, the process proceeds to step S25, and the ID of the ID card in the received received electric field strength notification signal is a new direct reception currently being processed by the own device. It is determined whether or not the ID matches, and if it does not match, it is processed as a separate communication content handling process to be described later in step S26, and the process proceeds to step S23 to continue waiting. On the other hand, if the ID of the ID card in the received reception field strength notification signal matches the new direct reception ID currently being processed by the own device, the process proceeds to step S27, and the received field strength represented by the received reception field strength notification signal. Is higher than the received electric field strength received by itself, and if so (as described above, the higher the received electric field strength, the shorter the standby time is set, so in most cases ) Determines that the own device does not have the master right, moves to step S28, deletes the corresponding new direct reception ID, and ends the processing. On the other hand, in step S27, if the received electric field strength indicated by the received received electric field strength notification signal is lower than the received electric field strength received by the own device, the own device may become the master, and the step S24 is performed. The process proceeds to the confirmation processing of the received electric field strength.

  FIG. 21 is a flowchart for explaining in detail the reception field strength confirmation processing in step S24. In step S31, a received electric field strength notification signal including information indicating the received electric field strength is broadcast-transmitted simultaneously to other lighting fixtures in the ID of the own card and the ID of the ID card that has received the search reply signal. In step S32, it is determined whether or not a received electric field strength notification signal from another lighting fixture has been received. When not received, that is, when steps S21 to S23 are repeated in FIG. 20, the process proceeds to step S33. It is determined whether or not the waiting time has elapsed. If not, the process returns to step S32 to repeat the process, and when it has elapsed, the process proceeds to step S34. It is determined that there is, and the process is terminated.

  On the other hand, if the received electric field strength notification signal is received from another lighting fixture in step S32, the process proceeds to step S35, and the ID in the received received electric field strength notification signal is a new one that is currently being processed by the own device. It is determined whether or not it directly matches the received ID. If they match, the process proceeds to step S36, and it is determined whether or not the received electric field strength indicated by the received received electric field strength notification signal is higher than the received electric field strength received by the own device. If this is not the case, it is determined that there is a high possibility that the device will become a master, and after waiting in steps S33 and S32, the process proceeds to step S34. If this is the case, the device has the right of master. If it is determined that there is not, the process proceeds to step S37, the corresponding new direct reception ID is deleted, and the process ends.

  In step S35, if the ID of the received reception field strength notification signal does not match the new direct reception ID currently being processed by the own device, it is processed as a separate communication content handling process described later in step S38, The process proceeds to step S33 and the standby is continued. Thus, if the lighting fixture that has transmitted the received electric field strength notification signal does not receive a received electric field strength notification signal from another lighting fixture for a certain period of time, or if there is no response that it has a higher received electric field strength than its own device, The own device becomes a master, and dimming instruction signals as shown below are sequentially transmitted through the communication unit 27 so as to reach other lighting fixtures within the lighting control range, and the received electric field strength is the highest. Except for a high lighting fixture, it becomes a slave and performs dimming control in response to a dimming instruction signal transmitted via the communication unit 27.

  FIG. 22 is a flowchart for explaining in detail the active illumination control process in step S8. If it is determined in step S7 that the own device is a master, the processing unit 22 turns on the illumination means 3 100% through the illumination control unit 23 in step S41. Further, in step S46, the ID of the ID card received by the own device, the current time, and the 100% dimming level are stored in the in-control ID table of the storage unit 21.

  Thereafter, the distance table held in the storage unit 21 of the own device as shown in Table 1 is referred to, and the following processing is performed for each lighting fixture within the control target range. In step S42, the dimming instruction signal is transmitted. In step S43, it is determined whether or not a dimming reply signal for the dimming instruction signal transmitted from the corresponding lighting fixture is received. If received, the process ends. If not received, the process proceeds to step S44, where it is determined whether or not a predetermined waiting time has elapsed with respect to the dimming return signal. If not, the process returns to step S43 and the standby is continued. In step S44, when a predetermined waiting time elapses, it is determined that the corresponding luminaire is faulty, and in step S45, the ID of the luminaire considered to be faulty and proxy control are required. The proxy control instruction signal representing is broadcasted and the process is terminated. Each lighting fixture that has received the proxy control instruction signal refers to the distance table from the ID of the lighting fixture that requires proxy control, is a fixture adjacent to the own device, and is within the control target range, for example, As shown in Table 2, 100% full lighting is performed by proxy.

  In step S3, when a signal from another lighting fixture is received, and in step S6, master determination processing is performed, or the ID of the received electric field strength notification signal received in steps S25 and S35 is currently being processed by the own device. At the next processing timing when the new direct reception ID does not match, the process moves to step S9, and the communication content handling process shown in FIG. 23 is performed. In this communication content handling processing, even if the own device does not receive the search reply signal from the ID card (S1-S2-S3) or receives the received electric field strength notification signal from another lighting device, the own device Since the search reply signal from another ID card is being received (S25-S26, S35-S38), it is determined in step S51 whether the received signal is the received electric field strength notification signal, If so, the contents of the signal received in step S52 are discarded and the process is terminated. If not, the process further proceeds to step S53 to determine whether the signal is a dimming instruction signal.

  In step S53, if it is a dimming instruction signal, the process proceeds to step S54 and a passive illumination control process described later is performed to end the process. If it is not a dimming instruction signal, the process further proceeds to step S55 to perform proxy control. It is determined whether or not it is an instruction signal. If it is a proxy control instruction signal, the process proceeds to step S56 and a proxy control process described later is performed and the process is terminated. If it is not a proxy control instruction signal, the contents of the signal received in step S52 are discarded and the process is terminated. .

  FIG. 24 is a flowchart for explaining in detail the passive illumination control process in step S54. In step S61a, the dimming level is calculated from, for example, Table 2 according to the remaining distance of the received dimming instruction signal. Subsequently, in step S61b, the ID of the ID card in the dimming instruction signal received by the own device, the reception time, and the dimming level obtained in step S61a are stored in the in-control ID table. In step S61c, the lighting unit 3 is dimmed and controlled at the highest dimming level among the stored contents in the ID table under control.

  Thereafter, referring to the distance table, the following processing is performed for each of the other lighting fixtures excluding the transmission source of the received dimming instruction signal. First, in step S62, a new remaining distance is obtained by subtracting the distance between the transmission source and the own device from the remaining distance of the dimming instruction signal. In step S63, it is determined whether or not the new remaining distance is smaller than 0. If so, it is determined that the own device is the last lighting device in the lighting control range, and adjustment to other lighting devices is performed. The process is terminated without transmitting the light instruction signal. Otherwise, it is determined that there is a possibility that the own device is not the last lighting device in the lighting control range, and step S64 is performed similarly to steps S42 to S45. In S67, the dimming instruction signal is transmitted including the proxy control signal.

  On the other hand, FIG. 25 is a flowchart for explaining in detail the proxy control process in step S56. In step S71, it is determined whether or not the ID of the proxy control target instrument based on the received proxy control instruction signal is within the control target range of the distance table of the own device. If it is within the range, 100% full in step S72. Lights up and ends the process. If it is not within the range, the process ends directly.

  Furthermore, in step S01, if the human sensor 28 detects a change of a certain amount or more, the human sensor corresponding process in step S03 is performed, and then the process returns to step S1. FIG. 26 is a flowchart for explaining in detail the human sensor processing in step S03. In step S91, it is determined whether or not the change is a change in which a person has entered the detection range. If so, the process proceeds to step S92, and the illumination unit 3 is fully lit through the illumination control unit 23. . Further, in step S93, a flag indicating that the user does not carry the ID card, the current time, and the 100% dimming level are stored in the in-control ID table of the storage unit 21.

  Thereafter, referring to the distance table held in the storage unit 21 of the own device as shown in Table 1, the step S42 is performed for each lighting fixture that is within the control target range (in this case, only the neighboring lighting fixture). Similarly to S45, the dimming instruction signal is transmitted in Steps S94 to S97, including the case of the proxy control signal.

  In step S02, when it is time to update the in-control ID table, the in-control ID table update process in step S04 is performed, and then the process returns to step S1. FIG. 27 is a flowchart for explaining in detail the updating process of the in-control ID table in step S04. The following processing is executed for each element in the in-control ID table held by the own device. In step S101, the delay time (5 minutes, 1 minute, 30 seconds) corresponding to the trigger ID that triggered the dimming control is confirmed. In step S102, the delay time has elapsed from the control end timing. In step S103, the ID is deleted from the in-control ID table and the process proceeds to step S104. Otherwise, the process proceeds directly to step S104. In step S104, the lighting means 3 is dimmed and controlled in accordance with the highest dimming level in the stored contents of the ID table being controlled, and the process is terminated.

  Furthermore, in step S2, if there is a control end target ID among the IDs currently under dimming control, the process proceeds to step S10, and the control end target ID held by the own device is controlled as shown in FIG. Termination processing is performed. That is, the illumination unit 3 is turned off through the illumination control unit 23 in step S81.

  Here, a specific dimming control operation by receiving a search reply signal from the ID card 2 will be described with reference to FIGS. 29 and 30. FIG. These figures show a case where the user carrying the ID card having the ID of C1 is closest to the lighting fixture L1 in the appliance arrangement shown in FIG.

  FIG. 29 shows a state in which each lighting fixture L is normal, and the search reply signal from the ID card is received by the lighting fixtures L1, L2, L4, and L5. In this case, the luminaire L1 has the highest received electric field strength, the luminaires L2 and L4 are medium, and the luminaire L5 is received with an electric field strength that barely exceeds the threshold that can be determined to be received. In the remaining lighting fixtures L3, L6 to L9, the received electric field intensity does not exceed the threshold value.

  Then, by the received electric field strength confirmation process in step S24, the master determination process in step S6, and the like, the luminaire L1 becomes the master and lights 100%, and the luminaire in the control target range shown in Table 1 from the communication unit 27. A dimming instruction signal having a remaining distance of 4 m representing the illumination control range is transmitted to L2 and L4. As a result, the lighting fixtures L2 and L4 serving as slaves refer to the distance table from the remaining distance, and subtract the distance between the own device and the lighting fixture L1, and the updated remaining distance is 2 m. Therefore, 70% of the light is turned on from Table 2, and the dimming with the remaining distance of 2 m is applied to the adjacent lighting fixtures L3; L5 and L7 except for the lighting fixture L1 that is the transmission source of the dimming instruction signal. Transfer the instruction signal. As a result, the lighting fixtures L3; L5 and L7 are also lit at 30%. However, the value of the remaining distance is 0 m, and the dimming instruction signal is not transferred, and the remaining lighting fixtures L6, L8, and L9. Remains off. In this way, the state shown in FIG. 29 is obtained. Thereafter, each lighting fixture L periodically transmits a search signal, and keeps the current dimming state unless the reception state of the search reply signal from the C1 ID card changes.

  On the other hand, FIG. 30 shows a state where the lighting fixture L2 is out of order, and the search reply signal from the ID card is received by the lighting fixtures L1, L4, L5, and the lighting fixture L1 is the master. The lighting fixtures L4, L5, and L7 that did not cause a problem in the transmission of the dimming instruction signal were turned on at 70%, 30%, and 30%, respectively, as in FIG. To do. However, the lighting fixture L1 that has not received the dimming response signal for the dimming instruction signal from the lighting fixture L2 adds the IL2 of the ID of the lighting fixture L2 to the ID C1 of the ID card, and performs proxy control. Broadcast instruction signals. Of the lighting fixtures that have received this, as shown in Table 1, the lighting fixtures L3 and L5 include the lighting fixture L2 within the control target range of their own equipment, so that the above-mentioned 30% lighting is originally performed. , 100% lights on behalf of. Since the remaining lighting fixtures L4, L6, L7, L8, and L9 do not include the lighting fixture L2 in the control target range of their own machine, the state does not change, and the lighting fixtures L4 and L7 are 70%, The lighting fixtures L6, L8, and L9 remain turned off. In this way, the state shown in FIG. 30 is obtained.

  As described above, in the lighting control system of the present invention, when the lighting means 3 is turned on and dimmed automatically by recognizing the presence or absence of a user, lighting control is performed on or near the lighting fixture L itself. While the device 4 is provided and the ID card 2 carried by the user returns the search reply signal in response to the search signal from the lighting control device 4, the lighting control device 4 turns on the lighting means 3. In addition, since the dimming control is performed, the presence or absence of the user can be recognized on the lighting apparatus L side without any movement of the user or without the user being aware of it, and a relatively narrow range near the user Can be appropriately controlled for lighting and dimming. In this way, dimming according to the position of the user is automatically performed, and both improvement in convenience and energy saving can be easily realized. Moreover, since a control aspect changes according to recognized ID (said C1, C2), more suitable lighting and dimming control can be performed.

  Furthermore, a human sensor 28 is provided, and when the presence of the user is detected by the human sensor 28, the lighting control device 4 turns on the lighting means 3, so the ID card 2 is not carried. Even when the user C3 approaches, the lighting control can be automatically performed in the same manner as the configuration used conventionally. Thereby, without impairing the convenience of the user C3 who does not carry the ID card 2, the users C1 and C2 who carry the ID card 2 as described above without being aware of it, Appropriate control can be performed.

  In addition, while the lighting fixture L2 that is relatively close to the user is out of order, the lighting control is performed so that the surrounding lighting fixtures L3 and L5 complement it, thereby minimizing the decrease in convenience. be able to.

  In the above description, although the illuminance is controlled (dimmed) according to the distance to the user, only the lighting / extinguishing control may be performed, or the user exists in the constantly lighting state. In this case, only dimming control such as increasing the illuminance may be performed.

[Embodiment 2]
FIG. 31 is a perspective view showing an external shape of an ID card 2a in a lighting control system according to another embodiment of the present invention, FIG. 32 is a block diagram showing its electrical configuration, and FIG. FIG. 34 is a perspective view showing an external shape of a lighting fixture La in a lighting control system according to another embodiment of the present invention, and FIG. 34 is a block diagram showing an electrical configuration of the lighting control device 4a in the lighting fixture La. . These ID card 2a and lighting fixture La are similar to the ID card 2 and lighting fixture L shown in FIGS. 2 and 3 and FIGS. 4 and 5, respectively, and the same reference numerals are used for the corresponding parts. A description thereof will be omitted.

  It should be noted that in the present embodiment, the ID card 2a includes a push button switch and the like, and an operation unit 31 that is operated by the user is provided. Correspondingly, the storage unit 11a stores the ID card. A control code that should be a mode for setting the stationary user C1 is stored together with the ID of 2a. When the operation unit 31 is operated, the processing unit 12a matches the control code with the ID. Sending a setting mode signal. In addition, the luminaire La includes an operation state display unit 32 composed of a light emitting diode or the like. When the setting mode signal is received, the processing unit 22a serving as a setting unit performs the operation according to the procedure stored in the storage unit 21a. The status display unit 32 is turned on to display the status in the regular user setting mode, and transmission / reception is performed with other lighting fixtures via the communication unit 27 to automatically perform the following settings.

  That is, in the setting mode, among the lighting fixtures that have received the setting mode signal from the ID card 2a, a mode transition signal is broadcasted to the other lighting fixtures from the lighting fixture that has become the master by the master determination process described above. Then, the processing units 22a of the other lighting fixtures that have received this are simultaneously set to the setting mode, the operation state display unit 32 is turned on, a search signal is transmitted within a predetermined period, and the ID of the received reply signal is automatically set. The ID is stored in the storage unit 21a of the machine, and the IDs are mutually exchanged via the communication unit 27, and all IDs received by the respective lighting fixtures La are registered as the regular user C1 belonging to the office 52. To do. The ID registered as the steady user C1 is controlled by increasing the delay time until the light is turned off as described above during normal control.

  The operation unit 31 includes an electrode part that is touched by a user and a cover thereof. When the user presses the cover part, the electrode comes into contact and is energized. The processing unit 12a periodically reads this, detects that there is an input due to a voltage change, and shifts to the setting mode. When the operation unit 31 is not operated, the ID card 2a returns the search reply signal in response to the search signal and realizes the lighting and dimming control as in the case of the ID card 2 described above. However, when the operation unit 31 is operated, a setting mode signal in which the control code is matched with the ID is transmitted as described above, and the lighting apparatus La is shifted to the setting mode.

  This ID card 2a does not have a power source as described above, and therefore, when the radio signal receiving unit 15 receives a search signal when the operation unit 31 is pressed, and when the search signal is received. When the operation unit 31 is pressed, the setting mode signal is transmitted through the transmission unit 14. However, a means to be a secondary battery such as a capacitor is provided, the fact that the operation unit 31 is pressed in a state where the search signal is not received is stored, and then the radio wave reception unit 15 is searched within a certain time. The configuration mode signal may be returned when a signal is received.

  Below, the outline | summary of the setting operation | movement of this Embodiment is demonstrated.

  As shown in FIG. 35, the users C11 to C14 who want to use as the stationary user C1 are at the detection position of the luminaire La of the present system. Among them, the user C11 holds the ID card 2a that can shift to the setting mode. When the ID card 2a becomes communicable with any of the lighting fixtures La in the system, a reply signal is returned in response to the search signal. In the state of FIG. 35, the lighting fixture L9 has the highest received electric field strength. It is assumed that L6 and L8 are medium and L5 is barely above the threshold, and the remaining lighting fixtures L1 to L4 and L7 do not reach the threshold. Thereby, each lighting fixture L5, L6, L8, L9 performs the master determination process shown in above-mentioned FIG. 20, determines the lighting fixture L9 as a master, and the above lighting and light control are performed.

  When the user presses the operation unit 31, the setting mode signal is transmitted, and the lighting fixture L9 receives the control code. Therefore, it is determined that the user's instruction is to shift to the setting mode, and the other lighting fixture L1. -L8 transmits an instruction to shift to the setting mode. Each of the lighting fixtures L1 to L8 and the lighting fixture L9 that have received the setting mode transition instruction lights up the operation state display unit 32 and initializes a stationary user stored in each storage unit 21a. Or you may ensure the temporary area | region for setting modes in the memory | storage part 21a.

  The lighting fixtures L1 to L9 that have shifted to the setting mode perform only the steady user ID search process for a certain period of time thereafter. Or, by pressing the operation unit 31 of the user C11 holding the ID card 2a again, until a search reply signal is received from the ID card 2a, or until a normal mode transition instruction is received from the luminaire L9 that has received it The steady user ID search process may be performed. And each lighting fixture L1-L9 may receive 1 or more ID during the said fixed time. In FIG. 36, the lighting fixture L5 receives the user C14, the lighting fixture L6 receives the users C12 and C14, the lighting fixture L8 receives the user C13, the lighting fixture L9 receives the users C11 and C13, and the other lighting fixtures L1 to L1. L4 and L7 are assumed not to receive any ID. In this way, the user ID is searched.

  Each lighting fixture L1-L9 complete | finishes ID search process at the time of fixed time progress, after transfering to setting mode. Thereafter, the received ID stored at that time is set as data of the steady user notification signal, and is broadcast to other lighting fixtures in the system. A signal collision at the time of broadcasting can be avoided by a method such as determining the transmission start time using the ID of each lighting fixture. When each of the lighting fixtures L1 to L9 receives the stationary user notification signal from another lighting fixture, the lighting fixtures L1 to L9 analyze the data set in the signal and acquire the IDs of the ID cards 2 and 2a. If there is an ID that is not yet stored as a steady user ID, it is stored in the storage unit 21a as a steady user ID. As a result, when the broadcast communication of all the lighting fixtures L1 to L9 is completed, all the lighting fixtures L1 to L9 in the system store the IDs of C11 to C14 as regular users. In this way, user IDs are exchanged.

  The luminaire for which the broadcast communication of the steady user notification signal is completed returns to the normal mode. When the return processing is performed in the order in which the broadcast communication is completed, when the signal collision avoidance method is used in the broadcast communication as described above, a certain lighting device has already returned to the normal mode, but another lighting device Can occur during broadcast communication or before starting, but this can be solved by accepting a steady user notification signal even in the normal mode. Alternatively, the luminaire that became the master during the transition to the regular user setting mode broadcasts a steady user notification completion confirmation signal every fixed time, and each luminaire has completed the broadcast communication of the regular user notification signal or has not yet completed. The master returns a response indicating that the response has not been completed, and when all responses indicate completion, the master broadcasts a normal mode return notification signal, and each luminaire receiving the broadcast returns to the normal mode. May be taken. In this way, the normal mode is restored.

  When returning to the normal mode, the operation state display unit 32 is turned off. As a result, the user is notified that the setting of the stationary user has been completed normally. Further, when the setting cannot be performed normally, the user may be notified of the setting abnormality by blinking or the like. If the user confirms the operation state display unit 32 of each of the lighting fixtures L1 to L9 and wants to redo the setting, the same setting is performed by pressing the operation unit 31 of the ID card 2a again. In the above description, when the setting mode signal is received from the ID card 2a, the mode is shifted to the setting mode. However, the above-described distance setting and sensitivity setting are performed on a part or all of the lighting fixtures La without providing the dedicated ID card 2a. A switch or the like may be provided.

  37 to 39 are flowcharts for explaining the above-described operation in more detail. Hereinafter, the operation in the present embodiment will be described in detail with reference to these drawings.

  First, FIG. 37 is a flowchart for explaining in detail the steady user setting process by the processing unit 22a. This process branches in the process of FIG. 18 described above by inserting a determination as to whether a setting mode signal has been received somewhere in the path of steps S1, S01, S2, S3, S4, and S02. Be started. In step S111, it is determined whether or not it is the transmission timing of the search signal to the ID cards 2 and 2a. If so, the process proceeds to step S113 after performing a steady user search process to be described later in step S112. The process directly proceeds to step S113. In step S113, it is determined whether or not a predetermined search time has elapsed since the start of the search process. If not, the process returns to step S111 to continue the search process. A regular user ID exchange process described later in step S114 is performed, and after shifting to the normal mode in step S115, the process ends.

  FIG. 38 is a flowchart for explaining in detail the steady user search process in step S112. In step S121, the search signal is transmitted. In step S122, it is determined whether or not a search reply signal from the ID card 2 or 2a responding thereto is received. Is temporarily stored in the storage unit 21a, and the process returns to step S122 to repeat reception. When no new search reply signal is received, the process proceeds to step S124. In step S124, it is determined whether or not a specified standby time of the search reply signal has elapsed. If not, the process returns to step S122 to continue the reception operation. In step S123, the ID temporarily stored in step S123 is stored in the storage unit 21a as the steady user ID, and the process ends.

  FIG. 39 is a flowchart for explaining in detail the steady user ID exchange processing in step S114. In step S131, as described above, in order to prevent signal collision, it is determined whether or not the notification start timing defined in advance for each luminaire is reached. When the start timing is reached, the process proceeds to step S132 and the storage unit 21a If there is an ID stored in, the regular user notification signal is created based on the ID, and after starting broadcast transmission, the process proceeds to step S133. If the start timing is not reached, the process proceeds directly to step S133. In step S133, it is determined whether or not a stationary user notification signal has been received from another lighting fixture. If received, the process proceeds to step S134, and the user ID in the stationary user notification signal is stored in the storage unit 21a. After storing the ID, the process proceeds to step S135, and if not received, the process proceeds directly to step S135. In step S135, it is determined whether or not the specified communication time of the steady user ID has elapsed. If not, the process returns to step S131 to continue the transmission and / or reception operation. In step S136, the broadcast transmission is terminated and the process is terminated.

  In this way, when the setting mode is entered, the ID card 2, 2a is automatically searched for ID, and the obtained ID data is exchanged and registered between the lighting fixtures La. A user who holds 2a can be registered only by being in the detection range, and the user can be easily set. As a result, the group of the above-mentioned stationary user C1, the group of the non-stationary user C2, and the group of the user C3 that does not hold the ID card can be grouped, and the mode corresponding to each group as described above can be controlled. become. Further, the registration work can be further simplified by collecting the ID cards 2 to be registered and performing the above-described registration work, and then distributing the registered ID cards 2 to each user.

  Here, in Japanese Patent Laid-Open No. 2002-289369, a control signal is received by a master device by a specific low power radio from a controller, and further transferred to a slave device by a weak radio, so that a plurality of installations can be performed with simple installation work. There has been proposed a lighting device that can control lighting fixtures in conjunction with each other. Therefore, although communication between instruments is disclosed, it is impossible to expect special effects by communicating electric field strength and distance information as in the present invention.

  Moreover, in the said Unexamined-Japanese-Patent No. 7-122368, when the code | symbol which all the receivers by the side of a lighting fixture should respond from a remote control, a lighting fixture transmits a search signal, and a remote control responds to it, It is also disclosed to notify the location of the remote control whose whereabouts are unknown.

  Therefore, although the search signal is disclosed, the search reply signal that responds to the search signal is used as in the present invention, and the stepwise dimming is performed centering on the luminaire near the user. It is not possible to expect any effective effects.
