Description

  The present invention relates to a maintenance system, and more particularly to a maintenance system for an automatic dimming lighting apparatus using a solid light emitting element as a light source.

  In recent years, environmental awareness has increased, and solid-state light-emitting elements, particularly light-emitting diodes (hereinafter referred to as LEDs), have attracted attention as new light sources that can replace incandescent lamps, fluorescent lamps, mercury lamps, and other lamps. This is because the LED is a light source that has a longer life than the lamps described above and does not contain harmful substances such as mercury and lead, that is, it is an environmentally friendly light source.

  Among LEDs, a so-called high power LED having an input capacity of 1 W or more has a high emission intensity and is optimal for lighting applications. In addition, the light conversion efficiency of LEDs has been improved year by year, and in the future, illumination using high-power LEDs as light sources is also expected to become energy-saving light sources.

  Here, in the lighting fixture using LED, there exists a type which can perform dimming freely using the characteristic of LED itself. This is because the LED can freely change the light emission intensity according to the supplied current value. There are various methods for performing the dimming. For example, there is a method in which some information is provided in the lighting fixture in advance and the dimming is performed based on the information (hereinafter referred to as an automatic dimming lighting fixture). .

  Here, when applying an automatic dimming lighting fixture to a large space such as a factory or an office, it is common to use a plurality of automatic dimming lighting fixtures at the same time in order to obtain the necessary illumination. It is. In such a case, if there is an error in the information held by each automatic dimming lighting fixture, there will be a mismatch in the dimming of each automatic dimming lighting fixture (for example, each installed in the office) Automatic dimming lighting fixtures are dimmed apart). This can cause a loss of convenience for the user. Therefore, there is a need for a main tense system for matching information held in a plurality of automatic dimming lighting fixtures.

  In view of such a situation, in the lighting device disclosed in Patent Document 1, infrared signals are exchanged between the remote control and the lighting fixture. Based on the request from the remote controller, the operating state of the lighting fixture is transmitted to the remote controller. The remote controller displays the received operating state of the lighting fixture on the display unit. By doing in this way, it is supposed that the user can instruct | indicate a desired operation state to a lighting fixture via a remote control, referring the operation state of the lighting fixture displayed on a display part.

According to the above, it seems that the lighting device disclosed in Patent Document 1 may be used as a maintenance system for matching information held in the plurality of automatic light control lighting fixtures as described above.
JP 2002-260877 A

  However, in practice, it is difficult to use the lighting device disclosed in Patent Document 1 as a maintenance system for matching information held in the plurality of automatic light control lighting fixtures as described above.

  The maintenance system as described above assumes that a plurality of automatic light control lighting fixtures are provided. On the other hand, the lighting device disclosed in Patent Document 1 must instruct a desired operation state by a remote controller for each lighting fixture. Therefore, in the illuminating device of patent document 1, in order to instruct | indicate an operation state with respect to several lighting fixtures, it is feared that a big effort and complicated operation will be needed. Furthermore, individually instructing the operating state for each lighting fixture may cause a new inconsistency.

  Moreover, in the illuminating device disclosed by patent document 1, when a some luminaire is provided, grouping beforehand is also disclosed. In this case, an instruction can be given to a plurality of lighting fixtures in the group at a time.

  However, even if such a grouping is performed, it is difficult to use the lighting device disclosed in Patent Document 1 as a maintenance system for matching information held in the plurality of automatic light control lighting fixtures as described above. It is. This is because maintenance can be performed only in units of groups. For example, it is impossible to perform maintenance on an arbitrarily selected automatic dimming lighting fixture. This causes a loss of convenience for the user.

  DESCRIPTION OF EMBODIMENTS Hereinafter, embodiments of a maintenance system according to the present invention will be described in detail with reference to the drawings.

First, the configuration of the maintenance system of the present invention will be described.
FIG. 1 is a perspective view showing an external appearance of a maintenance system 1 of the present invention. FIG. 2 is a cross-sectional view showing the structure of the A direction surface of the automatic light control lighting device 2.

  As shown in FIG. 1, the maintenance system 1 includes an automatic dimming lighting fixture 2 and a terminal 9. A plurality of automatic dimming lighting fixtures 2 are provided, but only one automatic dimming lighting fixture 2 is shown here. The automatic light control lighting device 2 includes a housing portion 31.

Below, the automatic light control lighting fixture 2 is demonstrated first.
The power supply device 3 corresponds to a component excluding the transmission / reception means of the power supply unit of the present invention, and is constituted by an outlet 7 and a housing 22. The power supply device 3 converts alternating current power (commercial power) into direct current and supplies direct current to the plurality of solid state light emitting elements 33. The power supply device 3 is arranged in a hollow structure on the attachment direction side where the solid light emitting element 33 is not provided, out of the two hollow structures included in the housing unit 31.

  Here, the housing 22 is a chopstick box-type case and has an appearance on the power supply device 3. Here, for example, the size of the housing 22 is the same size as the chopstick box. Further, the casing 22 accommodates circuit elements constituting the power supply device 3 therein. The shape of the housing 22 is not limited to this shape. A cylindrical shape may be sufficient and other shapes may be sufficient.

  The communication unit 4 (corresponding to the transmission / reception means of the present invention) is provided for performing communication using a wireless communication line with the terminal 9 and is attached to the casing unit 31. The attachment position of the communication unit 4 with respect to the housing part 31 may be arbitrary, but at least the communication antenna part 5 (corresponding to the antenna of the present invention) may be attached in a state exposed to the outside of the housing part 31. is necessary.

  The communication antenna unit 5 is a communication interface using a wireless communication line, and the casing unit 31 is made of metal as described later. Therefore, in a state where the communication antenna unit 5 is housed therein, a so-called shielded state is obtained, and stable communication may not be obtained. Therefore, the inventors have thought that it is desirable that the communication antenna unit 5 be attached in a state of being exposed to the outside of the housing unit 31.

  The confirmation lamp 6 corresponds to the notification means of the present invention, and is turned on when reception is performed in the communication unit 4. Accordingly, a user (not shown) of the maintenance system 1 can visually confirm that reception is performed. In addition, the confirmation lamp 6 may be lit in a blinking manner when reception is performed, and may notify the outside of the automatic light control lighting device 2 by this.

  Further, a solid light emitting element 33 may be used as a configuration corresponding to the notification means of the present invention instead of the confirmation lamp 6. That is, when reception is performed in the communication unit 4, the solid-state light emitting element 33 may emit light in a specific pattern (for example, blinking is turned on) to notify the outside of the automatic light control lighting device 2. . At this time, all of the solid light emitting elements 33 may emit light in a specific pattern, but only a part of the solid light emitting elements 33 may emit light in a specific pattern. What is important is that a user (not shown) of the maintenance system 1 can visually confirm that reception is performed.

  The outlet 7 is used for the power supply device 3 to use a commercial AC power supply, and connects the commercial power supply 41 and the power supply device 3.

  The housing | casing part 31 is corresponded to the housing | casing means of this invention. The power supply device 3, the substrate 32, a plurality of solid light emitting elements 33, and a protective translucent plate 34 are provided therein. Further, the communication unit 4 holds the communication antenna unit 5 in a state exposed to the outside of the housing unit 31. Furthermore, the confirmation lamp 6 is also held.

The casing 31 is formed in a substantially H-shaped cross section. That is, it is configured to have two hollow structures. The casing 31 is made of a metal having a high thermal conductivity (preferably, a metal having a thermal conductivity of 200 W · m ⁻¹ · K ⁻¹ or more). For example, the housing part 31 is made of aluminum. The reason why aluminum is used for the housing part 31 is that it is inexpensive, easy to form, has good recyclability, has a thermal conductivity of 200 W · m ⁻¹ · K ⁻¹ or more, and heat dissipation characteristics. Is high. Further, it is desirable that the casing 31 is made of aluminum and then anodized. Alumite treatment increases the surface area and enhances the heat dissipation effect.

  In addition, the housing | casing part 31 is not limited to this shape, For example, a cylindrical shape etc. may be sufficient. You may determine arbitrarily according to the condition where the automatic light control lighting fixture 2 is installed.

The substrate 32 is disposed inside a hollow structure formed by the casing portion 31 and the protective translucent plate 34. The substrate 32 is formed on the surface of the surface facing the protective translucent plate 34 inside the hollow structure. The substrate 32 is made of a metal having a high thermal conductivity (preferably, a metal having a thermal conductivity of 200 W · m ⁻¹ · K ⁻¹ or more). Preferably, the casing 31 is made of the same material. For example, the substrate 32 is made of aluminum.

  Here, it is preferable to make the housing | casing part 31 and the board | substrate 32 contact each other. This is because the air conduction between the casing 31 and the substrate 32 inhibits the heat conduction between the casing 31 and the substrate 32, which makes it impossible to perform more efficient heat treatment. is there. That is, it is preferable to increase the adhesion between the casing 31 and the substrate 32 by configuring the casing 31 and the substrate 32 with the same material. Furthermore, it is preferable to perform press working to further improve the adhesion.

  When performing the above-mentioned press working, a material having adhesiveness (for example, a double-sided tape without an adhesive or a base material) (not shown) is sandwiched between the casing portion 31 and the substrate 32, and the adhesiveness between the two. Is preferably increased.

  When using a double-sided tape, it is important to select one that does not contain a substrate. This is because the base material has a low thermal conductivity, so that the heat conduction from the housing portion 31 to the substrate 32 is hindered.

  It is also preferable to divide the substrate 32 into a plurality of parts. This is because, when the linear expansion coefficients of the casing 31 and the substrate 32 are different, the adhesion between the casing 31 and the substrate 32 deteriorates when the temperature of the automatic light control lighting device 2 rises. This is to prevent it. By dividing the substrate 32, the length in the longitudinal direction of each substrate 32 is shortened. Thereby, the expansion amount per one board | substrate 32 becomes small. Therefore, it becomes easy to absorb the difference in expansion between the casing 31 and the substrate 32 with an adhesive material, and thus the adhesion between the casing 31 and the substrate 32 can be easily maintained. This method of dividing the substrate 32 is particularly effective when the length of the automatic light control lighting device 2 in the longitudinal direction is long.

  The plurality of solid state light emitting elements 33 are disposed on the substrate 32. The plurality of solid state light emitting elements 33 are, for example, LEDs. The solid state light emitting device 33 is a so-called high power LED with a power consumption per unit of 1 W or more, and is a surface mount type LED. The high power LED has a high luminous intensity and is suitable for lighting equipment. When the automatic light control lighting device 2 is used as general illumination, the emission color of the solid-state light emitting element 33 to be used preferably corresponds to daylight color, daylight white, white, warm white, or light bulb color. Specifically, for example, the plurality of solid-state light emitting elements 33 include daylight colors, daylight whites, whites, warm whites defined in 4.2 “Chromaticity Range” of JISZ9112 “Classification by light source color and color rendering of fluorescent lamps”. Or it emits light corresponding to the color of the bulb.

  The protective translucent plate 34 is disposed on the light emitting direction side where the solid light emitting element 33 is provided, and has translucency. The protective translucent plate 34 is formed in a flat plate shape. By integrally combining the casing 31 and the protective translucent plate 34, the cross section becomes a substantially square shape.

  The protective translucent plate 34 is made of translucent glass, acrylic resin, polycarbonate, or the like. Fine irregularities are unevenly formed on the front or back surface of the protective translucent plate 34 by surface treatment. This surface treatment can be easily performed, for example, by applying a sandblast method. The protective translucent plate 34 protects the solid light emitting element 33 and the like disposed inside the automatic light control lighting device 2. Further, the protective translucent plate 34 plays a role of diffusing light emitted from the solid state light emitting device 33. The light emitted from the solid state light emitting element 33 has strong directivity and tends to be irradiated locally. By diffusing the light emitted from the solid state light emitting element 33 with the surface-treated protective translucent plate 34, the directivity of the light can be weakened and the light can be uniformly irradiated over a wide area.

  The shape of the protective translucent plate 34 is not limited to the above, and may be arbitrarily set according to the shape of the housing portion 31. What is important is that it is made of a translucent material.

Next, the terminal 9 will be described.
The terminal 9 (corresponding to the maintenance terminal of the present invention) is for operating the automatic dimming lighting fixture 2. You may comprise with a common notebook personal computer. The terminal 9 is provided with a communication card 10 (corresponding to the terminal transmission / reception means of the present invention), which uses a wireless communication line with the communication unit 4 provided in the automatic light control lighting device 2. Used for communication. In addition, a user (not shown) of the maintenance system 1 is provided with an input button 11 for input for operation and a display screen 12 (corresponding to the display means of the present invention) for displaying various information.

  When the terminal 9 is configured using a notebook computer or the like, the communication card 10 is preferably configured to be connectable through an interface generally provided in the notebook computer or the like. For example, it may be configured as a PC card or connectable using a USB terminal. By doing in this way, it becomes possible to comprise the terminal 9 simply.

  Here, as described above, the maintenance system 1 includes a plurality of automatic dimming lighting fixtures 2. For example, as shown in FIG. 3, nine automatic dimming lighting fixtures 2 (of course, the number of automatic dimming lighting fixtures 2 is not limited to this number), and the maintenance system 1 may be used as the lighting of the office 201. . Here, the automatic light control lighting device 2 is provided on the ceiling surface of the office 201, nine units 2a, 2b, 2c, 2d, 2e, 2f, 2g, 2h, and 2i.

  Further, when using the maintenance system 1 in the office 201 as described above, if the terminal 9 is configured with a notebook computer as described above, a user of this office 201 (an employee working in this office: not shown) However, it is possible to maintain the automatic dimming lighting apparatus 2 (2a, 2b, 2c, 2d, 2e, 2f, 2g, 2h, 2i) using the notebook personal computer used for business. Since the terminal 9 can be configured using a notebook personal computer used for business without using a dedicated device, there is a merit that it leads to cost reduction and convenience improvement.

  Here, the maintenance system 1 will be described based on the functional block diagram shown in FIG.

  The automatic light control lighting device 2 includes a rectification unit 42, a selection unit 43, a microcomputer unit 44, a communication unit 4, a solid state light emitting element 33, and a confirmation lamp 6.

  The microcomputer unit 44 includes a memory 44a, and the communication unit 4 includes a communication antenna unit 5.

  The terminal 9 includes a communication card 10, an input button 11, and a display screen 12. The communication card 10 includes a terminal memory 10a and a terminal antenna unit 10b.

  The automatic light control lighting device 2 supplies direct current to the solid state light emitting element 33 and the confirmation lamp 6 to emit light using an alternating current power source supplied from a commercial power source 41 which is an external power source.

  Specifically, the commercial power source 41 is a power source that is supplied from an electric power company to a general household, a business office, and the like, and supplies alternating current to the automatic light control lighting device 2.

  The rectifier 42 converts the sine wave voltage of the AC power source into a pulsating flow. Specifically, the AC voltage supplied from the commercial power supply 41 is full-wave rectified, and the full-wave rectified waveform is output to the selection unit 43.

  The selection unit 43 outputs the voltage of the pulsating flow in which the duty ratio, which is the ratio of the on time during which the pulsating flow output from the rectifying unit 42 is passed and the off time during which the pulsating flow is not passed, is controlled. Specifically, the full-wave rectified waveform output from the rectifying unit 42 is divided at a predetermined time interval, and the full-wave rectified waveform divided at the predetermined time interval is divided within each period of the predetermined time interval. Transform to voltage of pulse waveform.

  Here, by controlling the duty ratio, light emission from the solid light emitting element 33 and the confirmation lamp 6 can be dimmed (indicating that the light emission intensity can be changed freely including turning on and off). This means that controlling the duty ratio of the output has the same meaning as controlling the amount of power within a unit time. Therefore, the light emission from the solid light emitting element 33 and the confirmation lamp 6 can be dimmed by controlling the duty ratio of the output.

  The selection unit 43 achieves the above by being controlled by the microcomputer unit 44.

  The microcomputer unit 44 includes a function corresponding to the correcting means of the present invention. The microcomputer unit 44 includes a memory 44a.

  First, the memory 44 a holds a unique number assigned to each automatic light control lighting device 2. Furthermore, a dimming schedule or the like is held. Here, the dimming schedule holds the dimming schedule as a time table as shown in FIG. 5, for example. As shown in FIG. 5, this time table shows the time and dimming performed when the time is reached. In this time table, the dimming is displayed as a percentage, and this indicates the ratio of the light emission intensity to 100% of the light emission intensity at the time of full lighting.

  The microcomputer unit 44 has a built-in clock (not shown). The microcomputer unit 44 controls the selection unit 43 to perform dimming according to the dimming schedule held in the memory 44a based on the time indicated by the timepiece (not shown). That is, the automatic light control lighting device 2 performs light control automatically according to the light control schedule.

  Further, the microcomputer unit 44 corrects the dimming schedule held in the memory 44a and the time indicated by a built-in clock (not shown) as a function corresponding to the correcting means of the present invention.

  Specifically, first, it is checked whether or not a designated number included in a signal (hereinafter referred to as a correction signal) distributed from the communication card 10 of the terminal 9 and received by the communication unit 4 matches its own unique number. . Only when they match, based on the correction signal, the dimming schedule held in the memory 44a and the time indicated by a built-in clock (not shown) are corrected.

  Further, when the correction signal is received by the communication unit 4, the microcomputer unit 44 controls the selection unit 43 to turn on the solid light emitting element 33 and the confirmation lamp 6 (for example, blinking). This is to notify the outside of the automatic light control lighting device 2 that the communication unit 4 is receiving a signal.

  Further, the microcomputer unit 44 has a unique number, a dimming schedule, and a time indicated by a clock (not shown) in the microcomputer unit 44, which are assigned to each automatic dimming lighting fixture 2 held in the memory 44a in the microcomputer unit 44. Are sent to the communication unit 4.

The solid light emitting element 33 and the confirmation lamp 6 are turned on by the output from the selection unit 43.
The communication unit 4 includes a communication antenna unit 5. A signal (hereinafter referred to as an illumination signal) is distributed from the communication unit 4 through a wireless communication line. The illumination signal includes a unique number assigned to each automatic dimming lighting fixture 2 held in the memory 44a in the microcomputer unit 44, a dimming schedule, a time indicated by a clock (not shown) in the microcomputer unit 44, and the like. It is a signal based on the information. The data is distributed to the terminal 9 by the communication antenna unit 5. Further, the correction signal distributed from the communication card 10 of the terminal 9 is received by the communication antenna unit 5, and this signal is sent to the microcomputer unit 44.

  The communication card 10 includes a terminal memory 10a and a terminal antenna unit 10b. The terminal memory 10 a holds a unique number of the automatic light control lighting device 2 that can be maintained using the terminal 9. This is held, for example, as a list shown in FIG. In this list, the unique number of the automatic light control lighting device 2 that can be maintained using the terminal 9 is described.

  In this way, the reason why the unique number of the automatic dimming lighting fixture 2 that can be maintained using the terminal 9 is maintained is, for example, in the vicinity of the automatic dimming lighting fixture 2a in the office as shown in FIG. In the terminal 9 held by a user (not shown) having a desk, it is considered that there is almost no need to maintain the automatic dimming lighting device 2i far from the desk. Rather, in order to avoid accidental maintenance, in a terminal held by a user (not shown) having a desk near the automatic dimming lighting device 2a, the automatic dimming lighting device 2i should not be maintained. There may be cases where it is better to place them. Based on the above, the unique number of the automatic dimming lighting fixture 2 that can be maintained using the terminal 9 is held in the terminal memory 10a.

  Further, the correction signal is distributed from the communication card 10 via the wireless communication line from the terminal antenna unit 10b. The correction signal is a signal for correcting the dimming schedule held in the memory 44a in the microcomputer unit 44 and the time indicated by a clock (not shown). The correction signal is based on information input by a user (not shown) via the input button 11 and the time indicated by the clock in the terminal 9.

  The correction signal includes a designation number for designating the automatic dimming lighting fixture 2 that performs maintenance. The designated number is arbitrarily selected from the list of unique numbers of the automatic dimming lighting fixture 2 that can be maintained and held in the terminal memory 10a (for example, the user via the input button 11). This is a unique number selected by (not shown). When a plurality of automatic dimming lighting fixtures 2 are designated, a plurality of designation numbers are included in the correction signal.

  Moreover, the illumination signal delivered from the communication unit 4 of the automatic light control lighting device 2 is received by the terminal antenna unit 10b and displayed on the display screen 12 based on this signal.

  The input button 11 is a keypad for inputting information necessary for a user (not shown) of the maintenance system 1 to perform desired maintenance.

  The display screen 12 displays information based on the illumination signal to the user (not shown), for example, the unique number of the automatic dimming lighting fixture 2, the dimming schedule, and the time indicated by a clock (not shown).

  Here, transmission / reception between the communication unit 4 and the communication card 10 is performed using a wireless communication line. This wireless communication line has a communicable distance of at least 10 [m], and even when the power supply device 3 (automatic dimming lighting fixture 2) is mounted at a high place, the terminal 9 controls the automatic dimming lighting fixture 2 It is possible to operate reliably.

  In addition, since the communicable distance is at least 10 [m] as described above, it is not necessary to operate the terminal 9 toward the automatic dimming lighting device 2 and the convenience of the user (not shown) is improved. be able to.

  Moreover, the format of the signal (correction signal, illumination signal) exchanged between the communication unit 4 and the communication card 10 is, for example, as shown in FIG. A signal exchanged between the communication unit 4 and the communication card 10 includes an ID unit 71 and a data unit 72.

  In the ID portion 71, the designation number of the automatic dimming lighting fixture 2 that performs maintenance is described in the correction signal, and the unique number of the automatic dimming lighting fixture 2 is described in the illumination signal.

  In the data section 72, regarding the correction signal, the dimming schedule held in the memory 44a, the correction value of the time indicated by a clock (not shown) built in the microcomputer unit 44, and the illumination signal, the automatic dimming illumination The dimming schedule held in the memory 44a of the appliance 2 and the time indicated by the clock (not shown) of the microcomputer unit 44 are described.

  Here, the amount of data of signals (correction signal, illumination signal) exchanged between the communication unit 4 and the communication card 10 is not as large as apparent from the above. Therefore, it is not necessary to employ a wireless communication line capable of high-speed data communication in the maintenance system 1, and a simple communication line may be used. For example, infrared communication may be used. Alternatively, standardized low-speed wireless communication may be used. By doing so, there is an advantage that the maintenance system 1 can be configured at low cost.

  Next, maintenance by the terminal 9 of the automatic light control lighting device 2 in the maintenance system 1 will be described based on the flowchart of FIG.

  In S <b> 81, the illumination signal distributed from the communication antenna unit 5 of the communication unit 4 of the automatic light control lighting device 2 is received by the communication card 10 (terminal antenna unit 10 b) of the terminal 9.

  The illumination signal may be distributed periodically at predetermined time intervals. For example, it may be automatically distributed once per minute. The illumination signal includes a unique number assigned to each automatic dimming lighting fixture 2 held in the memory 44a in the microcomputer unit 44, a dimming schedule, and a clock (not shown) built in the microcomputer unit 44. Information such as the time indicated by is included.

  In S82 of FIG. 8, the terminal 9 displays the content of the illumination signal received by the communication card 10 (terminal antenna unit 10b) on the display screen 12.

In such a case, if there is an error in the information (the dimming schedule or the time indicated by the internal clock (not shown)) held by each automatic dimming lighting device 2, Inconsistency occurs in the dimming (for example, each automatic dimming lighting fixture installed in the office is dimmed apart). This can cause a loss of convenience for the user. Therefore, the main tense system 1 for matching the information held in the plurality of automatic dimming lighting fixtures 2 is necessary.

  Here, when the lighting device disclosed in Patent Document 1 is to be used as a maintenance system for the automatic light control lighting device 2, the individual automatic light control lighting device 2 can be individually maintained. It is necessary in principle. Therefore, in the illuminating device of Unexamined-Japanese-Patent No. 2002-260877, there is a concern that a great deal of labor and complicated operations are required to perform maintenance on a plurality of automatic dimming lighting fixtures. Furthermore, individually instructing the operation state to each automatic dimming lighting device 2 may cause a new mismatch.

  As a method applicable to maintaining a plurality of automatic dimming lighting fixtures 2 at a time, a method of grouping automatic dimming lighting fixtures 2 is also disclosed. However, maintenance is performed only in units that are grouped in advance. I can't. This is a factor that impairs the convenience of the user.

  On the other hand, in the illumination system of the present invention, maintenance can be easily performed simultaneously on a plurality of automatic dimming lighting fixtures 2 desired by the user. Based on the same information, the dimming schedule of the plurality of automatic dimming lighting fixtures 2 and the time of the clock can be corrected. Therefore, it is possible to easily match the dimming of each automatic dimming lighting fixture 2.

  The maintenance system 1 of the present invention is not limited to the above embodiment, and can be freely modified and implemented without departing from the spirit of the present invention.

  For example, by including a signal for correcting the current light emission amount in the correction signal, it is possible to maintain the light emission amount from the automatic dimming lighting device 2 at the current time using the terminal 9. Specifically, a user (not shown) of the maintenance system 1 inputs information related to dimming desired to be realized in the automatic dimming lighting fixture 2 from the input button 11. Based on this, the unique number of the automatic dimming luminaire 2 for which the above-mentioned dimming is desired is included as a designated number, and the correction signal is distributed from the communication card 10 (terminal antenna unit 10b) of the terminal 9. This is received by the communication unit 4 (communication antenna unit 5) of the automatic light control lighting fixture 2. The microcomputer unit 44 of the automatic light control lighting device 2 instructs the selection unit 43 to correct the current light control based on the correction signal only when the designation signal matches its own unique number.

  As described above, in the maintenance system 1, the current light emission amount of the automatic light control lighting device 2 can be maintained using the terminal 9. In addition, the above is not limited to the amount of light emission, and can be used to correct color tone.

  Moreover, in the said embodiment, although the signal transmission / reception was performed between the automatic light control lighting fixture 2 and the terminal 9 using the wireless communication line, you may utilize a wired communication line.
