[0001]
BACKGROUND OF THE INVENTION
  The present invention relates to an illumination device installed in a relatively large space such as an indoor office.
[0002]
[Prior art]
  Conventionally, in a relatively large space such as an office, when the lighting is controlled in a group for each layout by changing the layout depending on the use, each lighting fixture 1 is shown in FIG.₁Assign an address to each lighting fixture 1₁Are commonly used by connecting them with the signal line 2 and controlling them with the control panel 3.
[0003]
  In this method, for example, as shown in FIG. 16, when divided into three zones A, B, and C, the lighting device 1 is placed in the A zone by the control panel 3.₁~ 1₃, 1₈~ 1₁₀, 1₁₅~ 1₁₇And lighting equipment 1 in the B zone₄~ 1₇, 1₁₁~ 1₁₄, 1₁₈~ 1₂₁Luminaire 1 in the C zone₂₂~ 1₂₈Is assigned to control the lighting / extinguishing individually for each zone.
[0004]
  Further, if the appliance is turned on only when there is a person in each of the zones A to C, the human sensors 101 and 102 are installed in the A zone as shown in the figure, and the illumination of the A zone is detected by each detection. Appliance 1₁~ 1₃, 1₈~ 1₁₀, 1₁₅~ 1₁₇To light up. Similarly, the human sensors 103 and 104 in the B and C zones, respectively.,105 and 106 are installed, and lighting equipment 1 of each B and C zone₄~ 1₇, 1₁₁~ 1₁₄, 1₁₈~ 1₂₁ ,1₂₂~ 1₂₈To light up.
[0005]
[Problems to be solved by the invention]
  By the way, with the above method, it is necessary to assign individual addresses to individual lighting fixtures. If there are many lighting fixtures, the number of addresses to be assigned increases, and mistakes such as duplicating and assigning addresses during construction. There was a possibility of causing.
[0006]
  Furthermore, once an address is assigned, it operates according to that address, so there is a problem that the zone cannot be assigned unless the address of the device is reserved, especially when reassigning after construction. .
[0007]
  Similarly, in order to change the current zone assignment, it is necessary to check in advance the address of the luminaire corresponding to the assignment, and it is difficult to say that anyone can easily change it. Usually, when such a change work is involved, it is necessary for a specialized worker to perform it, and it may be expensive each time, so it is not a good method.
[0008]
  Furthermore, in the case of the conventional method, it is necessary to wire a signal line to each lighting fixture in advance in order to control it in a lump, and the construction becomes large compared to the one that only connects the power supply, and the workability is greatly inferior. There was also a problem.
[0009]
  Therefore, as a method of not connecting the signal lines, there is a method of performing wireless communication between the luminaires using infrared as a signal medium. There was a problem that I could not.

DETAILED DESCRIPTION OF THE INVENTION
  The present invention will be described with reference to basic examples and embodiments.
[0022]
  (Basic example 1)
  FIG. 1 shows a basic configuration diagram of a luminaire 1 used in this basic example. The luminaire 1 transmits information to a light source 10, a receiving unit that receives information from another luminaire 1, and another luminaire. A communication unit 11 that is selectively provided with a transmitter, and further a setting device composed of sensors such as a human sensor and an illuminance sensor, and controls and manages the communication unit 11, and a dimming / lighting circuit for the light source 10 And a control unit 12 that controls lighting of the light source 10, and the content of the communication unit 11 is selected according to the illumination system to be constructed.
[0023]
  2A shows an example in the case where a communication unit 11a having only a receiving unit is provided, for example, and FIG. 2B shows an example in which a communication unit 11b having a setting device and a transmission unit is provided. In the former case, the control unit 12 takes in the information of the other lighting fixtures 1 received by the receiving unit of the communication unit 11a. On the other hand, in the latter, under the control of the control unit 12, information on the setting device of the communication unit 11 b or information from the control unit 12 is transmitted to other lighting devices 1 in the vicinity through the transmission unit.
[0024]
  As a signal transmission medium used for communication of information between the luminaires 1, light, for example, infrared rays is used, and the transmission unit of the communication unit 11 a is 360 degrees centering on the luminaire 1 as shown in FIG. A lighting fixture separated by one unit (shown with hatching) can be transmitted as indicated by an arrow, and as shown in FIG. There is one that can transmit to a lighting fixture 1 that is separated by one unit. The white frame part in FIG. 3 shows the lighting fixture in the range where the transmitted signal does not reach directly.
[0025]
  When the transmission medium uses infrared as the transmission medium as described above, the transmission direction and distance are set and adjusted by providing a filter that can be adjusted according to the direction, or appropriately depending on the luminance.
[0026]
  FIG. 4 shows an example of a lighting system according to the present basic example. In this lighting system, lighting fixtures 1A to 1X are arranged in 8 × 3, and in the arrangement shown in the drawing, the lighting shown in FIG. The fixture 1 is arrange | positioned as a 1J, 1M, 1O lighting fixture, and the lighting fixture 1 of Fig.2 (a) is arrange | positioned as another lighting fixture. Note that the transmission ranges of the transmission units of the lighting fixtures 1J, 1M, and 1O are those in which the transmission range is set in the range described with reference to FIG. In FIG. 4, the alphabets of symbols attached to the respective lighting fixtures merely indicate their positions, not addresses.
[0027]
  Thus, the information transmitted from the transmission unit of the lighting fixture 1J is the surrounding lighting fixtures 1A to 1C around the lighting fixture 1J.,1I,1K, 1Q to 1R will be transmitted, and these nine lighting fixtures 1A to 1C, 1I to 1K, and 1Q to 1S constitute the α zone.
[0028]
  The information transmitted from the lighting fixture 1M is the surrounding lighting fixtures 1D to 1F around the lighting fixture 1M.,1L,1N, 1T to 1V is transmitted, and the nine zones of 1D to 1F, 1L to 1N, and 1T to 1V constitute a β zone.
[0029]
  Furthermore, the information transmitted from the lighting fixture 1O is the surrounding lighting fixtures 1F to 1H around the lighting fixture 1O.,1N,1It is transmitted to P, 1V to 1X, and the γ zone is constituted by these nine lighting fixtures of 1F to 1H, 1N to 1P, and 1V to 1X.
[0030]
  Thus, in the lighting system using this basic example, if the setting device provided in the communication unit 11b of the lighting fixtures 1J, 1M, and 1O is a setting device that sets the dimming level, the setting device sets the lighting device. The information indicating the dimming ratio is transmitted to other neighboring lighting fixtures through the transmitter in each lighting fixture 1J, 1M, 1O, and each of the lighting devices 1J, 1M, 1O in the zones α, β, γ to which the lighting fixtures 1J, 1M, 1O belong The control unit 12 of the lighting fixture performs dimming control with the dimming ratio received by the light source 10. As a result, it is possible to perform illumination control with different dimming ratios depending on the α to γ zones.
[0031]
  Note that the lighting fixtures 1F, 1N, and 1V operate on any information of the lighting fixtures 1M and 1O. Therefore, when the information overlaps, it may be set to give priority to any one.
[0032]
  When it is detected that the setting device is a human sensor and a person is present in the detection area of the human sensor, detection information is transmitted through the transmission unit of the lighting fixture 1J, 1M, or 1O. The light sources 10 of the lighting fixtures in the zones α, β, or γ to which the lighting fixtures 1J, 1M, or 1O belong can be controlled to be turned on simultaneously.
[0033]
  Of course, when there is no further human detection, transmission of the detection information is stopped and the light sources 10 of the lighting fixtures in the zone to which the lighting fixture belongs are controlled to be turned off all at once, or are turned off after a certain period of time after the detection information is lost. It is like that.
[0034]
  In the above case, when identification information (ID) is not added to the transmitted detection information, the luminaire that has received the detection information operates based on the received detection information. , 1N, 1V operate with respect to any detection information of the lighting fixtures 1M, 1O. For example, during operation based on detection information from one lighting fixture (eg, 1M), the other lighting fixture (eg, 1O) When the detection information from the other lighting fixture is received1Switch to the operation based on the detection information of O (prioritized later) or conversely1It is only necessary to appropriately set whether to ignore the O detection information and continue the operation based on the detection information received first (first priority), and to handle the overlap of information.
[0035]
  In addition, when adding identification information (ID) to the detection information, the priority order may be determined by the identification information (ID) in addition to the prior priority as described above (for example, 1A> 1B>). 1C ...).
[0036]
  The setter may have the identification information (ID) alone, or the detection information may be transmitted according to the identification information unique to the lighting fixture.
[0037]
  (Basic example 2)
  In the basic example 1, the setting device such as the sensor is provided as the communication unit 12b together with the transmission unit. However, in this basic example, as shown in FIG. As shown in FIG. 5 (b), the setting device 13 composed of a sensor such as a human sensor or an illuminance sensor is used to attach it detachably to the mounting portion 14 provided in the lighting fixture 1 as necessary. Use things. In order to transmit and receive information, a transmission / reception unit 15 corresponding to, for example, an infrared signal is provided.
[0038]
  In the illustrated case, the transmitter / receiver 15 is provided in all of the lighting fixtures 1, but only the receiving portion may be provided in the lighting fixture 1, and the transmitter may be attached at the same time when the setting device 13 is attached.
[0039]
  Thus, in the system shown in FIG. 4 described above, if the lighting fixture 1 of this basic example is used for the lighting fixtures 1J, 1M, and 1O, the lighting fixtures 1I, 1K, 1N, and 1O can be easily used as shown in FIG. The setting device 13 can be attached to the zone setting, and the zone setting as shown in FIG. 4 can be easily changed to the zone setting as shown in FIG. In FIG. 6, α to δ indicate the set zones.
[0040]
  (Embodiment 1)
  The present embodiment uses the lighting fixture 1 having a transmission function for further transmitting received information through its own transmission unit, and enables information to be transmitted to the lighting fixtures 1 in other zones. .
[0041]
  That is, for example, when the lighting fixtures 1A to 1X are arranged as shown in FIG. 7, when the lighting fixture 1J having a setting device such as a human sensor transmits the detection information, the transmission range is as shown in FIG. In the case of (a), the detection information transmitted from the lighting fixture 1J is the lighting fixtures 1A to 1C in the α zone.,1I,1K, 1Q to 1R is directly transmitted.
[0042]
  Assuming that the directly transmitted information is J information, each of the lighting fixtures 1A to 1C that has received the J information.,1I,1K, 1Q to 1R transmit this J information. This indirect information to be transmitted is referred to as J ′ information (in this case, a mark indicating indirect information is attached. In the description, “′” is attached for simplification).
[0043]
  This J 'information is the lighting fixtures 1A to 1C in the same α zone.,1I,1K, 1Q-1R, 1J are also received, but because the J information has already been received, or because it is information transmitted by itself, these lighting fixtures 1A-1C,1I,1Ignored for K, 1Q to 1R, 1J.
[0044]
  On the other hand, the J ′ information transmitted from the lighting fixtures 1C, 1K, or 1S adjacent to the other zones is received by the lighting fixtures 1D, 1L, and 1T.
[0045]
  When the lighting fixtures 1D, 11, and 1T receive this J 'information, the lighting fixtures 1D, 11, and 1T further transmit to the surroundings through their own transmission units.
[0046]
  In this way, J 'information is sequentially transmitted in the right direction in the figure.
[0047]
  Here, J ′ information is ignored in the lighting fixtures 1D to 1H, 1L to IP, and 1T to 1X other than the α zone, which does not directly receive the J information, and the lighting control operation based on the J ′ information is ignored. Do not do.
[0048]
  Of course, when receiving J information which is direct information, when receiving indirect information from other zones, when not receiving information, three kinds of lighting control patterns are given to the control units 12 of the respective lighting fixtures 1A to 1X. It may be set and each lighting fixture 1A-1X may control based on this pattern.
[0049]
  Of course, lighting fixtures with setting devices, in the example shown, 1J, 1M, and 1O lighting fixtures control lighting based on detection of the setting device, and other operations when receiving and not detecting indirect information The same control as that of the luminaire is performed.
[0050]
  By sequentially transmitting information (bucket relay type) as described above, the detection information of the lighting fixture 1J can be transmitted to the entire system. Of course, the detection information of 1M and 1O lighting fixtures can be transmitted in the same manner.
[0051]
  Thereby, it becomes possible to measure the detection frequency of the setting device of the whole system for every setting device in one place in the system, for example, the receiving unit of the lighting fixture 1X.
[0052]
  At this time, it is assumed that the adjacent lighting fixtures directly receive information, but a predetermined number of bucket relays are used.ShineInformation received by the light fixture 1 may be directly handled as information, and information transmitted thereafter may be used as indirect information. FIG. 8 shows an example. If the central lighting fixture 1S having a transmission unit whose transmission direction is the same as that shown in FIG. 3B transmits the detection information, the transmitted detection information is It is received directly at each lighting fixture of 1K, 1R, 1T, 1c. The received detection information is transmitted from each lighting fixture of 1K, 1R, 1T, and 1c. The transmitted detection information is transmitted to the lighting fixtures 1C, 1J, 1L, 1Q, 1U, 1b, 1d, and 1k. Further, detection information is transmitted from the lighting fixtures 1C, 1J, 1L, 1Q, 1U, 1b, 1d, and 1k to the surroundings. For example, 1C, 1J, 1L, 1Q, 1U, 1b , 1d, and 1k are directly detected, and the detection information transmitted from each of the 1C, 1J, 1L, 1Q, 1U, 1b, 1d, and 1k is handled as indirect information. You may do it.
[0053]
  (Embodiment 2)
  In this embodiment, a zone having a function of giving identification information (hereinafter referred to as “sensor ID”) when transmitting the detection information of the sensor as the setting device described in the first embodiment is overlapped and expanded. It is a thing.
[0054]
  FIG. 9 shows a processing flowchart of the control unit 12 that assigns the sensor ID of each lighting fixture 1 at this time. First, the flow chart of FIG. 9 will be described. When sensor ID information is directly received (input) as information, the luminaire 1 stores and stores the sensor ID information as a data group D (x). . When the data string K including the direct information A <notation of data A> is received, the data string K and the data group D (x) are collated, and the data group D (x) includes the direct information A. If so, D (x) is added to the data string K (K = K + D), and the data string K is transmitted (output).
[0055]
  This process will be described using a specific example.
[0056]
  In the system shown in FIG. 10A, when a setting device that is a human sensor detects, for example, when a human sensor having a sensor ID “J” of a 1J lighting fixture detects, a transmission unit of the lighting fixture 1J Transmits the information of the sensor ID “J”.
[0057]
  This direct information “J” is transmitted to the entire system as indirect information “J ′” as in the first embodiment. The lighting fixtures 1A to 1C, 1I, 1K, and 1Q to 1S that receive the direct information “J” do not receive the direct information of other IDs, and transmit the indirect information “J ′” as they are.
[0058]
  On the other hand, when the human sensor which is a setting device of the lighting fixture of 1O detects, "O" of sensor ID of this human sensor is transmitted from the lighting fixture 1O as information.
[0059]
  The luminaire 1N that receives this direct information “O” is a luminaire that also receives “M” from the luminaire 1M as direct information. Therefore, sensor IDs “M” and “O” exist in the accumulated data group (data group D (x) in FIG. 9).
[0060]
  Therefore, as shown in FIG. 10B, when the information “O” is directly received, the information is transmitted on the assumption that a human sensor having a sensor ID “M” in addition to “O” is also detected. That is, the information transmitted from the lighting fixture 1N is indirect information “O′M ′” that the human sensor corresponding to the sensor IDs “O” and “M” has detected both.
[0061]
  Further, the 1M and 1E lighting fixtures that have received this indirect information “O′M ′” are lighting fixtures that directly receive or transmit information “M”, but direct information other than “M” is stored. Therefore, no further sensor ID is given.
[0062]
  The lighting control operation of the luminaire that has received the information with the sensor ID includes indirect information corresponding to the ID information received directly as the information in the ID data string such as “O′M ′”. If it is, perform the same operation as when you obtained information directly.
[0063]
  The control flowchart is shown in FIG. In the flowchart of FIG. 11, when sensor ID information is directly received as information, the luminaire 1 stores and stores the sensor ID information as a data group D (x). When the data string K including the direct information A or the indirect information A ′ <the information is expressed as data A> is received, the data string K is collated with the data group D (x), and the data group D ( x) If the data A is included, the lighting control is performed by determining that the data A is equivalent to the case where the information A is received directly. Continue to light up. Then, the data string is transmitted (output).
[0064]
  Thereby, for example, when the human sensor of the 1O lighting apparatus detects, the 1L or 1D lighting apparatus can be operated as if it was detected by the human sensor of the 1M lighting apparatus.
[0065]
  That is, the β zone and the γ zone are set as the same zone that is subjected to the same control in response to either the human sensor of the 1O lighting fixture or the human sensor of the 1M lighting fixture.
[0066]
  For example, when the lighting device 1 is in a standby state, when there is detection information in the zone to which the lighting fixture 1 belongs, the light source 10 is turned on for a predetermined period from the detection information and then returns to the standby state. In addition, various conventional operations can be assumed.
[0067]
  Further, the number of overlapping zones is not limited to two, and there is no problem if three or more zones overlap. For example, if a 1V lighting device receives direct information “M”, “O”, and “Z”, it is transmitted from the 1V lighting device when a human sensor of the 1O lighting device detects it. The information may be "O'M'Z '", and a luminaire that receives the information, for example, 1U that receives the direct information of "M", has "M'" in the received data string. The same control as that when the human sensor of the 1M lighting apparatus detects is performed. This system example is not shown.
[0068]
  (Embodiment 3)
  FIG. 12 according to the present embodiment shows an example of a system in which 48 lighting fixtures of 8 × 6 are arranged. In this system, lighting fixtures of 1A to 1E, 1I to 1M, 1Q to 1U, and 1a to e are formed. Three zones are composed of a zone (A), a zone (1) consisting of 1F to 1H, 1N to 1P, 1V to 1X, 1f to 1h lighting fixtures and a zone (1) consisting of 1i to 1x lighting fixtures. is doing.
[0069]
  Here, as a lighting fixture of 1B, 1D, 1G, 1R, 1T, 1W, 1q, 1s, 1u, and 1w, a setting device including a sensor such as a human sensor and a transmission unit are used, and the lighting fixture is used. Yes. The transmission range of the transmission part of these lighting fixtures is based on Fig.3 (a). The sensor ID is set to # 1 to 10 unique to each setting device (human sensor), or if the lighting fixtures 1A to 1X, 1a to 1x have unique numbers, refer to this, It may be in the form of ID. With reference to this ID, each of the lighting fixtures 1A to 1X and 1a to 1x performs the operation shown in the second embodiment, so that the setting devices for the lighting fixtures 1B, 1D, 1R, and 1T are ) Zone lighting fixtures 1A to 1E, 1I to 1M, 1Q to 1U, 1a to e, and (1) Zone lighting fixtures 1F to 1H, 1N to 1G and 1W lighting sensors 1P, 1V to 1X, and 1f to 1h are further controlled by the lighting fixtures 1i to 1x in the (u) zone to the setting devices of 1q, 1S, 1u, and 1W, respectively.
[0070]
  (Embodiment 4)
  In the third embodiment, the setting device or the lighting fixture provided with the setting device has different IDs. In FIG. 12, <1B, 1D, 1R, 1T lighting fixture>, <1G, 1W lighting fixture>, In this embodiment, the same ID is transmitted with respect to the setting devices for the lighting fixtures in the same zone such as <1q, 1s, 1u, 1w lighting fixtures>. That is, in this embodiment, the lighting fixture does not need to perform the ID assignment work shown in Embodiments 2 and 3 during signal propagation, and includes indirect information only for the ID that it receives directly as information. The lighting control may be performed by recognizing that the setting device including, for example, a human sensor in the zone to which it belongs is detected. A sensor ID is not particularly given when transmitting information.
[0071]
  (Embodiment 5)
  In the present embodiment, as shown in FIG. 13, zones (A), 1F-1 including lighting fixtures of 1A to 1E, 1I to 1M, 1Q to 1U, 1a to 1e, and 1i to 1m.H, 1N to 1P, 1V to 1X, 1f to 1h, 1n to 1p zone (b), 1q to 1v zone (c), 1w, 1x zone (d) 1J, 1L, 1O, 1b, 1d, 1g, 1q, 1s, 1u, and 1w lighting fixtures corresponding to the lighting system divided into four zones) The range of direct transmission of the transmitting unit of the lighting device 1J, 1L, 1O, 1b, 1d, and 1g is assumed to conform to FIG. 3 (a). Further, by limiting the direct transmission range of the transmission unit of the 1q, 1s, 1u, and 1w lighting devices to be limited only in the left and right direction, it is possible to set a zone in a narrow range such as the lower row and the lighting devices 1w and 1x. .
[0072]
  In particular, in this embodiment, it is easy to realize when all the lighting fixtures have a transmission / reception unit used for information transmission, and a lighting fixture with a transmission unit attached to the setting device. Further, a means such as attaching a filter or a seal to the transmission unit in the lighting fixture in which the setting device is installed may be used.
[0073]
  (Embodiment 6)
  In the system shown in the third embodiment, the 1N, 1O, and 1P lighting fixtures are the lighting fixtures that receive the direct information transmitted by the 1G lighting fixture and the 1W lighting fixture, but the information is received once by the lighting fixtures 1G and 1W. Until the information is output, it is not stored in the lighting fixtures 1N, 1O, 1P. Therefore, when the power is turned off and the power is turned on again, for example, if the lighting fixture 1G does not transmit detection information, the lighting fixtures 1F, 1G, and 1H do not react even if the sensor of the lighting fixture 1W detects. .
[0074]
  Therefore, in the present embodiment, the lighting fixtures 1N, 1O, and 1P are provided immediately after the power is turned on by using a lighting fixture provided with a nonvolatile storage unit that stores direct information received in the past in the control unit 12. Can recognize that it is a luminaire that receives direct information of the luminaires 1G, 1W.
[0075]
  Thus, in the present embodiment, the zone setting can be stored even when the setting device of the lighting fixture 1G fails or is removed. In addition, when the storage unit is provided in this way, it is necessary to erase the storage when changing the zone setting. Therefore, as a means for easily resetting the storage unit, a command such as a reset switch or an optical signal is provided. Good.
[0076]
  (Embodiment 7)
  In the present embodiment, at the time of power-on, for example, a lighting fixture provided with a setting device such as a human sensor transmits detection information once, and the other lighting fixtures only need to receive this information. That is, even if the power is turned off once, information data can be directly stored every time the power is turned on again.

  In this embodiment, the specific IDIt is set, and the detection information of this specific ID is transmitted from the lighting equipment without adding the mark “′” indicating indirect information. As a result, the entire system can be operated collectively. Further, it can be used for all lighting in an emergency, the reset means of the sixth embodiment, and the like.
[0078]
  TheA luminaire that receives direct information of a specific ID can have a zone that can be controlled independently within the zone by not transmitting information of the specific ID.
[0079]
  For example, when the sensor ID “S” of a setting device made of, for example, a human sensor of a 1S lighting apparatus in FIG. 14 is a specific ID, according to the method of the above-described embodiment, due to the overlap of the zones of 1J, 1L, 1b, and 1d, Twenty-five lighting fixtures 1 are recognized as the same zone. At this time, regarding the lighting fixtures 1J, 1K, 1L, 1R, 1T, 1b, 1c, and 1d that directly receive the detection information of the lighting fixture 1S, if the detection information is received, it is not transmitted. When the setting device composed of the human sensor of the lighting fixture detects, since the detection information is not transmitted to the lighting fixtures other than the lighting fixtures 1J, 1K, 1L, 1R, 1T, 1b, 1c, and 1d, the lighting fixture 1S. Including the lighting fixtures 1J, 1K, 1L, 1R, 1S, 1T, 1b, 1c, and 1d [zone (e)], the lighting control is performed only.
[0080]
  Conversely, when the sensor of 1d lighting fixture detects, these nine lighting fixtures 1J, 1K, 1L, 1R, 1S, 1T, 1b, 1c, and 1d are also regarded as the same zone (A) and controlled. It will be. In this way, it is also possible to provide another zone that can operate only within one zone.
[0081]
  Moreover, the lighting fixture which accumulate | stored the direct information of specific ID may perform lighting control in response to the detection information of all ID.
[0082]
  In other words, for example, the setting ID including the human sensor provided in the 1q, 1s, and 1u lighting devices in FIG. The lighting fixtures 1q to 1v that receive this directly as information are controlled to be turned on even if any of the 1J, 1O, and 1x lighting fixtures transmits detection information. As this usage, for example, a lighting system installed in a common space such as a corridor in an office can be considered.
[0083]
  (Embodiment 9)
  The lighting holding time and the turn-off waiting time may be set according to the sensor ID described above. Furthermore, a lighting level or a turn-off standby level may be set according to the sensor ID.
[0084]
  For example, as shown in FIG. 15, for example, when a predetermined human sensor detects a human body at time t <b> 1 and the detection information is transmitted as a sensor ID, the lighting apparatus 1 that receives the sensor ID and performs a lighting operation The light source 10 determined in advance by the received sensor ID is turned on at a predetermined lighting level L1 until a predetermined lighting holding time T1 elapses, and then the light source 10 is dimmed and lit at the extinguishing standby level L2. It is possible to automatically control the lighting of the light source 10 such that it is held until the turn-off waiting time T2 elapses and then turned off.
[0085]
  By the way, although each said embodiment demonstrated the information transmission from a transmission part by infrared rays, you may use the light of other wavelengths, such as visible light. In addition, transmission is also possible by a method using radio waves or a method in which transmission lines are arranged around all the lighting fixtures 1 in a grid pattern.
[0086]
  In the case of infrared transmission, a circuit using a light emitting diode for the transmission unit and a photodiode for the reception unit may be used. In addition, in the transmission and reception of information, there are cases where signals overlap from various directions, but in order to reliably receive this, the transmission timing is changed for each lighting fixture. You may take the technique of changing. For example, in the case of the arrangement of each embodiment, it is a means of providing a transmission / reception unit having different wavelengths of light for carrying signals according to the transmission direction (the reception direction is the opposite direction) up, down, left and right. In addition, as a method of changing the timing, the transmission timing (the time from reception to transmission) is set randomly for each lighting fixture, and by setting the transmission timing in synchronization with the power supply frequency, a neighboring lighting fixture is set. For example, 1 means to prevent a signal from colliding.
[0087]
  When receiving the same signal from a plurality of directions at the same time, it may be considered that one signal has been received. When different signals are received, signals based on the respective signals in order according to the priority order. What is necessary is just to make it transmit.
[0088]
  Furthermore, although the configuration includes a setting device including a sensor, a control unit, and a transmission / reception unit in one lighting fixture, the configuration may be such that each is separated, for example, the transmission / reception unit transmits the sensor output as an information signal. The signal may be received by a control unit provided separately via another transmission / reception unit to control lighting.
[0089]
  Furthermore, although the said embodiment was demonstrated about the case where the said setting device is a human sensitive sensor, a setting device is comprised by other sensors, such as an illuminance sensor, The detection information of this setting device is transmitted, Based on this detection information Of course, the lighting control may be performed.
