  However, if an illuminance sensor is applied outdoors to control a street light, etc., the light or accidental reflection leaked from a nearby private house or building, or snow or dust near the illuminance sensor, compared to indoors, As a result, normal detection values cannot be obtained, and as a result, it becomes difficult to control the lighting device.

  In addition, when the management control device manages and controls a plurality of lighting devices, particularly when the number of lighting devices managed by one management control device becomes large, the management control device actually turns on or off according to an instruction to turn on or off. However, there is a disadvantage that a time lag occurs when each lighting device is turned on or off. If this is a large number of street lights installed in a certain geographical area, it means that a plurality of street lights existing in a certain area are turned on (off) at different timings. Absent.

The structure will be described in detail below.

  In the lighting device 1, an upper cover 2 serving as a main body is integrally formed of a material having excellent corrosion resistance such as aluminum die-casting, and an opening at a lower surface of the upper cover 2 has a light-transmitting cover 3 interposed with a seal packing 3A. Then, it is screwed to the mounting boss 2c via the screw hole 3a. The rear side of the top cover 2 is formed with an inclined portion 2a as shown in FIG. 1, FIG. 3, FIG. 6, etc., and one inclined end 2a-1 of the inclined portion 2a has an inclined portion. A lid 4 corresponding to the opening shape of 2a is connected to be openable and closable by a hinge 4a. By fixing the other inclined end 2a-1 of the lid 4 having no hinge 4a to the upper cover 2 with a mounting screw, the rear end face of the upper cover 2 and the front end face of the lid 4 are as shown in FIG. To be connected to

  As shown in FIG. 5, the upper cover 2 is formed with a through hole 2b through which the branch pipe B1 of the fixture B is inserted, and a plurality of mounting bosses 2c and a heat sink 2d of the light source unit 5 to be described later are provided in the interior of the room. As shown in FIG. A heat conductive plate 6 provided with a light source unit 5 is fixed to the heat sink 2d so that heat generated from each light emitting element 5a is guided to the heat sink 2d. The heat sink 2d absorbs the heat and dissipates it from the top cover 2 to the outside of the device. The light source unit 5 and the heat conductive plate 6 are fixed to a heat sink 2d by a holder 7. A power supply unit 8 is disposed at the rear of the light source unit 5, and a DC driving power obtained by converting a commercial AC power supply from the power supply unit 8 is supplied to the light source unit 5 through a lead wire 9.

  A lead wire 9 for guiding the commercial AC power to the power supply unit 8 is connected to a terminal block 10 disposed in an empty room of the inclined portion 2a of the top cover 2, and a cable for the commercial AC power is drawn out through the branch pipe B1. . In the space of the inclined portion 2a, there is provided a fixing fitting 12 for fixing the end of the branch pipe B1 inserted through the through hole 2b with the sealing ring 11 interposed therebetween.

  As shown in FIG. 7, the fixing bracket 12 includes a first support member 12a having an end portion on the mounting boss 2c, and a second support member 12b having an end portion screwed to another mounting boss 2c. A curved portion 12a-1 parallel to the axial direction of the branch pipe B1 is formed at the center of the first support member 12a, while a curved portion 12a-1 parallel to the axial direction of the branch pipe B1 is formed at the center of the second support member 12b. A flat step portion 12b-1 is formed, and the flat step portion 12b-1 is provided with a fixing screw 12b-2 for fixing and a positioning screw 12b-3 as shown in FIG.

  Next, the configuration of the light source unit 5 will be described in detail. The light source unit 5 has a plurality of chip-shaped light emitting elements 5a mounted on an insulating substrate 5b, and a pair of light source elements 5c fixed on a heat conductive plate 6 and slidable on the light source elements 5c. It mainly comprises a combination with a light control element 5d for controlling the emission direction of the light emitted from each light emitting element 5a by a lens-shaped light control member 5e.

  Next, the configuration of the power supply unit 8 will be described in detail. The power supply unit 8 includes a rectifier circuit 8a for converting a commercial AC power supply into a reduced DC as shown in FIG. 9, a light source lighting circuit 8 for lighting the light emitting element 5a with the DC power output from the rectifier circuit 8a, and lighting. A first light receiving element 8g-1 for detecting light and darkness outside the main body of the device 1, a second light receiving element 8g-2 for detecting the state of light emission of the light source unit 5, and illumination light emitted from the light transmitting cover 3 , A signal from each of the light receiving elements 8g-1 to 8g-3, and the relay switch 8p is driven based on the state of the input signal to drive the light emitting element 5a. , And an indicator lighting circuit 8e that lights the indicator 8e-1 or 8e-2 based on the judgment in the blinking control circuit 8d.

  As shown in FIGS. 7 and 8, the power supply unit 8 is formed by integrally forming a hollow housing case 8a and a slide plate 8b that covers an opening surface of the housing case 8a. A wiring board 8c on which the above-described circuit elements are mounted and a storage battery 8f for coping with a power failure or the like are housed. The outer periphery of the slide plate 8b has a flange shape projecting from the outer periphery of the housing case 8a, and darma holes 8b-1 are formed at four corners of the flange portion.

  As shown in FIG. 10, a first light receiving element 8g-1 is mounted on a wiring board 8c on the side of the housing case 8a. A through hole 8a-1 is formed in a side wall of the housing case 8a opposed to the first light receiving element 8g-1, and external light of the external environment is transmitted from the light receiving portions 2f formed on both sides of the upper cover 2. I am trying to introduce it. That is, the position of the upper surface cover 2 facing the through hole 8a-1 is formed in a recessed state, and the through hole 2f-1 is formed in the rear wall of the lighting part 2f. A daylighting packing 13 formed of a transparent material and fitted with the through-hole 2f-1 and the through-hole 8a-1 is coaxial.

  When the first light receiving element 8g-1 is provided on one of the sides of the power supply unit 8 configured as described above, the first light receiving element 8g-1 is connected to the light receiving unit 2f of the top cover 2 by the light receiving unit 2g. It is possible to dispose it facing any one. Such a function prevents a malfunction that illumination light from a lighting facility such as a house or a building around which the lighting apparatus 1 is installed becomes noise and is detected by the first light receiving element 8g-1 and is not turned on at night when it should be turned on. It can respond when it does.

  In such a case, avoid disposing the first light receiving element 8g-1 on the light noise entry side of the lighting unit 2f of the top cover 2 and select the lighting unit 2f which is not affected by the optical noise and select the power supply unit 8. Arrangements are possible. That is, in the case where the power supply unit 8 takes in light from the upper lighting unit 2f in FIG. 6 as shown in FIG. 6, when the influence of optical noise is confirmed, the small-diameter portion of the dharma hole 8b-1 is fixed. By loosening the mounting screw 14 and sliding the slide plate 8b to remove the head of the mounting screw 14 from the large diameter portion of the darma hole 8b-1, the entire power supply unit 8 can be rotated by 180 °. The arrangement direction can be changed as shown in FIGS. 11 and 12 so that light can be collected from the lower light-collecting unit 2f in FIG.

  Since a large number of the lighting devices 1 as described above are arranged as street lights in a certain geographical area such as an outdoor road or a park, the lighting state of each lighting device 1 in the range is transmitted to the management center. It is desirable to manage them collectively. In this case, the plurality of lighting devices 1 are managed by the server SV as a management control device. The processing and method for management control in such a server SV will be described below with reference to FIGS. It will be described based on the following.

  FIG. 14 is a diagram showing a configuration of the lighting device and the management control device according to the present invention, and FIG. 15 is an operation flow relating to the lighting device and the management control device. As shown in FIG. 14, the power supply unit 8 of each lighting device 1 in a predetermined area is connected to the server SV so that data communication is possible.

  The server SV may be provided with various means normally provided in a computer. Specifically, it includes an information processing unit J and a data transmission / reception unit MS1, the information processing unit J includes a processing device for processing data, and a storage device for storing data. In addition to the data described above, a program necessary for processing in the present invention is stored. The server SV is connected to a plurality of lighting devices 1 managed by the server SV via a communication line so that data can be transmitted and received.

  In addition, the server SV may appropriately connect various input means such as a keyboard and a mouse, and display means such as a monitor. The communication line may be a wired line such as the Internet, a telephone line, an optical line, or various wireless lines, or a combination thereof, and a conventionally known technique may be appropriately used.

  The power supply unit 8 of each lighting device 1 includes an ambient environment illuminance measurement unit AS that acquires a detection value of the first light receiving element 8g-1, a light emission control unit HC, and a data transmission / reception unit MS2. The light emission control unit HC includes a light source lighting circuit 8b, a blinking control unit 8d, and an indicator lighting circuit 8e. The power supply unit 8 also includes, in the light emission control unit HC, an operation by the microcomputer MC2 and a memory MO2 for storing necessary reference data and measurement data.

<Step 1: Confirmation of normal communication>
As shown in FIG. 15, the communication between the server SV and each lighting device 1 is a method in which polling is sequentially performed from the server SV to the data transmitting / receiving unit MS2 of each lighting device 1 at a predetermined timing. According to a control signal from the server SV, the wireless transmission / reception unit MS2 of the lighting device 1 is sequentially polled at a predetermined timing, and communication between the server SV and the lighting device 1 is confirmed. When a communication error occurs with the lighting device 1 as a result of this communication confirmation, a failure notification corresponding to the lighting device 1 in which the error has occurred is performed by a buzzer, LED light emission, or the like. This failure notification is displayed on the monitor of the server SV by characters or red light emission of the LED.

<Step 2: Ambient illuminance confirmation process>
If the communication confirmation is normal in step 1, the surrounding illuminance confirmation processing is performed. In this ambient illuminance confirmation process, a measurement instruction is issued from the server SV to the ambient environment illuminance measuring means AS of the lighting device 1. Specifically, the server SV transmits the ambient illuminance confirmation request data to the illuminating device 1, and the illuminating device 1 that has received the data has been detected by the first light receiving element 8g-1 by the ambient illuminance measuring means AS. The illuminance information including the detected value is created, and the illuminance information is transmitted to the server SV. At the same time, the lighting device 1 transmits light source state information indicating whether the light source unit 5 is turned on or off from the light emission control unit HC to the server SV. The server SV receiving these stores them in the storage device.

<Step 3: Comparative illuminance value calculation process>
Here, as a specific example, it is assumed that the server SV manages the six lighting devices 1a to 1f, and the illuminance information as shown in FIG. Shall be. That is, the result of the ambient illuminance confirmation processing is “illumination device 1a: 2lx, illumination device 1b: 201lx, illumination device 1c: 31lx, illumination device 1d: 42lx, illumination device 1e: 56lx, illumination device 1f: 1018lx”. I do.

  The server SV calculates the average value of the illuminance information collected from the lighting devices 1a to 1f as described above, and stores the calculated average value as a comparative illuminance value.

  The average value of the illuminance information collected from the plurality of lighting devices may be used as the comparative illuminance value as it is, but in practice, various calculations are performed so that the comparative illuminance value becomes a normal value. It is better to This is because the illuminance information collected from the lighting devices 1a to 1f may be inaccurate information affected by noise such as light leaking from nearby houses or reflected light generated by chance.

  For example, in the numerical values shown in FIG. 16, the illuminance information transmitted from the lighting device 1a is “2 lx”, which is lower than other values, and the illuminance information transmitted from the lighting device 1f is “ 1018 lx ". Such values are likely to be incorrect data that has been affected in some way, and it is desirable to exclude them.

  In order to obtain a more appropriate comparative illuminance value so as not to be affected by such data including noise, specific processing depends on the number of lighting devices managed by the server SV. The average value of the remaining values, excluding the maximum and minimum values, of the illuminance information collected from the lighting devices is set as a comparative illuminance value. For example, in the illuminance information illustrated in FIG. 16, the minimum is “2lx” received from the lighting device 1a, and the maximum is “1018lx” from the lighting device 1f. In this case, except for the two data “2lx” and “1018lx”, an average value is calculated based on the illuminance information from the remaining lighting devices 1b to 1e (here, it is 37.3lx). This may be used as the comparative illuminance value.

  When the number of lighting devices to be managed by the server SV is quite large, the illuminance information including noise may increase. In such a case, not only the maximum and minimum illuminance information but also a maximum value and a plurality of values close to this and a minimum value and this value, for example, excluding three data from the maximum and three data from the minimum, respectively. The average illuminance value may be calculated from the remaining illuminance information except for a plurality of values close to.

  As another method, a predetermined maximum reference value and a minimum reference value are stored in advance in the server SV, and the illuminance information larger (or higher) than the maximum reference value and smaller (or lower) than the minimum reference value. An average value may be calculated from the remaining illuminance information except for the illuminance information, and this may be used as the comparative illuminance value.

<Step 5: Light-on / off determination processing>
The comparison illuminance value thus calculated is compared with the reference data stored in the server SV in advance. According to the comparison processing, when the comparative illuminance value is greater than (or greater than) the reference data, that is, when the surroundings are bright, the server SV determines that the light source unit 5 of the lighting device 1 does not need to be turned on. .

  On the other hand, when the comparison illuminance value is smaller than (or smaller than) the reference data, that is, when the surroundings are dark, the server SV determines that the light source unit 5 of the lighting device 1 needs to be turned on. I do.

<Step 6: Lighting (light-out) instruction data transmission processing>
When it is determined that the light needs to be turned off by the light-on / off necessity determination processing, the server SV creates light-off instruction data for turning off the light source unit 5 of the lighting device 1 to be managed and transmits the data to each lighting device 1. I do.

  On the other hand, when it is determined that the lighting is necessary by the lighting / unlighting necessity determination processing, the server SV creates lighting instruction data for lighting the light source unit 5 of the lighting device 1 to be managed, and Send to

  In the lighting device 1 that has received the light-off instruction data, the light-emission control unit HC checks the light-on / off state of the light source unit 5, and if it is on, the light-emission control unit HC turns the light source unit 5 off by the light-source lighting circuit 8b. I do. If the issuance control unit HC confirms the light source unit 5 and it is already turned off, the light-off instruction data is discarded as it is.

  On the other hand, in the lighting device 1 that has received the lighting instruction data, the light emission control unit HC confirms the light-on / off state of the light source unit 5, and if not, the light-emission control unit HC turns on the light source unit 5 by the light source lighting circuit 8b. State. As a result of the issuance control unit HC confirming the light source unit 5, if it is already in the lighting state, the lighting instruction data is discarded as it is.

  The above steps 1 to 7 are repeatedly performed at a predetermined time interval for the plurality of lighting devices 1 managed by the server SV.

  As described above, in the invention according to the present embodiment, the illuminance information is obtained from each of the plurality of lighting devices 1 installed in a certain regional range, and the comparative illuminance value appropriately calculated from the plurality of illuminance information is used. Thus, the necessity of turning on or off the illuminating device 1 is determined, so that an illuminating device that performs an abnormal operation such as turning on even though the surroundings are bright can be eliminated.

  In addition, the illumination device 1 used in the invention according to the present embodiment integrally includes the ambient environment illuminance measurement unit AS (first light receiving element 8g-1) for measuring the ambient illuminance. As compared with the case where a device for measuring ambient illuminance is separately provided, unnecessary devices or various means can be reduced, so that the cost can be reduced. In addition, since the illuminance information of the location where the lighting device 1 is installed is used, it is possible to more accurately manage the lighting device installation environment in terms of lighting or extinguishing.

  As described above, the “lighting (light-out) instruction data” generated as a result of the “light-off / light determination process” is transmitted from the server SV to the plurality of lighting devices 1 managed by the server SV at the same time. There may be a time lag until the light source unit 5 of the lighting device 1 is turned on (or turned off) based on the above. The cause of the time lag is often due to the waiting time until the instruction data is actually transmitted from the server SV because the server SV sequentially transmits one instruction data for one lighting device. This time lag becomes more significant as the number of lighting devices 1 managed by the server SV increases. As described above, it is not appropriate for the scenery that a plurality of lighting devices in a certain geographical area are individually turned on (turned off).

  In order to prevent this, the lighting (light-out) instruction data transmitted from the server SV to each lighting device 1 includes predetermined time data. In addition, the lighting device 1 is provided with time counting means for counting time and acquiring time information. The time data included in the light-on (light-off) instruction data created by the server SV may be added to the light-on (light-off) instruction data by the server SV.

  The time at which the server SV creates the light-on (light-off) instruction data is obtained from the time obtaining means provided in the server SV itself. The server SV creates, as time data, a time obtained by adding a predetermined time interval (for example, one minute) to the obtained time. Specifically, it is assumed that the time when the server SV creates the lighting (light-off) instruction data is “19:11:02”. The server SV adds a predetermined time (here, 1 minute) to the obtained time “19:11:02” to create data indicating “19:12:02” as time data, The data is added to the lighting (light-off) instruction data and transmitted to each lighting device 1.

  When the lighting device 1 receives the lighting (extinguishing) instruction data to which the time data is added, the issue control unit HC of the lighting device 1 always obtains time information from the time counting means, and receives the time data from the server SV. And whether the time information from the time counting means matches.

  Triggered by the coincidence of the time data and the time information, the light emission control unit HC turns the light source unit 5 on or off by the light source lighting circuit 8b in accordance with the light-on (light-off) instruction data.

  By doing so, even when the number of lighting devices managed by the server SV becomes very large, the surroundings become darker than a predetermined illuminance, and the delay is delayed from when it is determined that lighting is necessary. In addition, it is possible to suppress the time lag when a large number of lighting devices are turned on, and to light them almost simultaneously.

  Embodiments of the present invention are not limited to the examples described above. In the above description, in the light-on / off determination processing, the server SV transmits the lighting (light-off) instruction data every time, and if the data is unnecessary, the server SV discards the data. In this regard, the server SV determines from the light source state information whether it is necessary to transmit the light-on (light-off) instruction data, and when it is not necessary, that is, when the light source state information indicates “light-on”. In the case where the lighting instruction data is created, even if the lighting instruction data is transmitted, it is only discarded, so that the processing may not be transmitted. As a result, unnecessary data on the communication line can be reduced, which is useful for eliminating delay and the like.

Further, in order to obtain a more stable operation of the lighting device 1, the following processing may be performed.
The "light-off / light-off determination process" and "light-on (light-off) instruction data transmission process" are determined based on the result of comparing the comparative illuminance value and the reference data a plurality of times, and light-on (light-off) instruction data is created. Or you may make it transmit. Only when the comparison result between the comparative illuminance value and the reference data is a plurality of times and the same result is obtained a predetermined number of times in succession, the lighting (light-off) instruction data is transmitted to the lighting device 1. .

  Specifically, as a result of comparison of the comparative illuminance value with the reference data, if the comparative illuminance value falls below the reference data, it is necessary to transmit lighting instruction data, but not based on only one comparison, Only when the comparative illuminance value falls below the reference data for an arbitrary number of times (for example, 10 times), the lighting (light-off) instruction data transmission processing is performed.

  In particular, when the comparative illuminance value is near the reference data, a situation in which the light source unit 5 of the lighting device 1 repeatedly turns on and off due to an error or the like is assumed, but this can be solved.

  The comparative illuminance value may be a value based on a geometric average of a plurality of pieces of illuminance information collected by the server SV, in addition to the above description. Further, the comparative illuminance value may be a median of a plurality of pieces of illuminance information collected by the server SV.

  The series of processes in steps 1 to 7 described above are repeatedly performed, but the time interval for each series of processes may not be constant. For example, when the comparative illuminance value differs from the reference value by a certain number or more, the time interval may be lengthened.

  Such a case where the comparative illuminance value has a certain number or more of difference from the reference value is a case of extremely bright or extremely dark time, such as during the day or midnight, but in such a case, It is wasteful to repeat the processing steps at predetermined short time intervals.

  Therefore, when the comparative illuminance value differs from the reference value by a certain value or more, such as during the daytime or midnight, the time interval between the series of processes is increased. Thereby, the frequency of data exchange between the server SV and the lighting device 1 can be suppressed, so that the load on the server SV, the lighting device 1 and the relay device between them can be reduced, and traffic can be reduced.

  In addition, second and third reference values may be used as reference values to be compared with the comparative illuminance value, and may be used for determination for dimming. More specifically, when the illuminating device 1 has a second reference value lower than the reference value serving as a reference for completely turning off the light and the comparative illuminance value is greater than (or greater than) the second reference value, the lighting device 1 An instruction to dimme the unit 5 is sent.

  Accordingly, when the surroundings gradually become brighter, the light amount of the lighting device 1 can be adjusted to the surrounding brightness, for example, by decreasing the light amount of the lighting device 1, so that fine dimming can be achieved. Can be

  Note that the illuminance information collected from each lighting device 1 to the server SV does not have to be data in which the illuminance is specifically digitized as described above. Specifically, the issuance control unit HC of the lighting device 1 includes a threshold determination unit. This threshold determination unit creates threshold determination information by comparing the illuminance information acquired from the ambient environment illuminance measurement unit AC with a threshold value also stored in the issuance control unit HC at predetermined time intervals. .

  When the threshold value determining unit compares the illuminance information acquired from the surrounding environment illuminance measuring unit AC with a predetermined threshold value, if the illuminance information is greater than (or greater than) the predetermined threshold value, the second illuminance information is created. Conversely, if the comparison result indicates that the illuminance information is smaller than (or smaller than) a predetermined threshold, the third illuminance information is created. The created second or third illuminance information is transmitted to the server SV.

  The server SV receives and stores the second or third illuminance information transmitted from each lighting device 1. The server SV counts the number (number) of the received second illuminance information. If the number of pieces of second illuminance information calculated by counting is greater than (or equal to or greater than) a predetermined reference value, it is not necessary to turn on the lighting device 1 (light source unit 5) in the light-on / off determination processing. Is determined. On the other hand, when the number of pieces of the second illuminance information is smaller than the predetermined reference value (or below), it is determined that the lighting device 1 (the light source unit 5) needs to be turned on in the light-on / off determination processing.

  In this case, the number of pieces of second illuminance information obtained by counting the second illuminance information is treated as a comparative illuminance value, and the reference data to be compared with this is a predetermined number stored in advance (for example, a server). The number of lighting devices 1 managed by the SV).

  Also, in the description here, the server SV counts the second illuminance information, but the third illuminance information may be counted. In this case, if the number of the third illuminance information is greater than (or greater than) a predetermined reference value in the light-on / off determination processing, the lighting device 1 (light source unit 5) is turned on in the light-on / off determination processing. If the number of pieces of third illuminance information is smaller than (or less than) a predetermined reference value, it is necessary to turn on the lighting device 1 (light source unit 5) in the above-mentioned lighting / light-out determination process. It is only necessary to determine that there is not.
