Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lighting device used in stores, offices and the like.

[0002]

2. Description of the Related Art In general, in stores such as convenience stores and supermarkets, offices, factories, and the like, lighting is performed for a long time in one day, so that it is necessary to consider energy saving.

[0003] As a lighting device for realizing energy saving,
2. Description of the Related Art Conventionally, there have been known ones that detect ambient illuminance and control the illuminance to be kept substantially constant, those that use natural light as illumination, and those that manage illumination time according to a schedule. What controls the illuminance to be almost constant,
Energy saving can be realized by not increasing light output more than necessary,
Energy saving can be realized by lowering the illuminance depending on the time zone or turning off the illumination during an unnecessary time zone. For example, during the preparation time before the store opening time, the lighting is thinned out and the illuminance at the time of lighting is set low, during the opening hours, the illuminance is set to an appropriate value. By setting, unnecessary lighting can be suppressed to save energy.

By the way, in order to compensate for a decrease in light output due to aging of the lamp and a decrease in light output due to contamination due to long-term use, the use time after replacement of the lamp is accumulated and the use time is increased. Accordingly, there has been conventionally provided an illumination device that performs dimming so as to increase the amount of dimming light. Here, the dimming amount means the ratio of the power supplied to the lamp to the rated value, and the light output of the lamp is almost constant by increasing the dimming amount (supplying power) as the operating time increases. Can be controlled. Also, by controlling the dimming amount to be 100% (the rated value of the supplied power) near the life of the lamp, the dimming amount is reduced at the start of use of the lamp to obtain an energy saving effect. is there.

That is, as shown in FIG. 13, the amount of light control immediately after lamp replacement is set to the ratio of the light output near the life to the rated light output of the lamp (for example, about 70%). The light control amount is increased with the use time so that the light control amount is set to 100% in the vicinity. By performing such control, the illuminance of the lamp (see the straight line a in FIG. 13) can be kept almost constant between the time immediately after the lamp replacement and the end of its life, and the illuminance can be adjusted until the lamp reaches its life. Since the light intensity is set to be smaller than 100%, compared to the case where the light intensity is set to 100% immediately after replacing the lamp, the power consumption is reduced by an amount corresponding to the shaded portion shown in FIG. And consequently energy saving. Here, the dimming light amount for keeping the light amount obtained from the lighting fixture substantially constant can be determined by the usage time after the lamp is replaced. The light intensity can be determined from the relationship with the light intensity.
Note that such a control method is referred to as initial illuminance correction control.

[0006] By using the above-described schedule control and initial illuminance correction control together, further energy saving can be realized. Further, there has been provided an illumination device capable of performing various controls using a human body detection sensor and an illuminance sensor.

[0007]

By the way, in operating the above-described lighting apparatus, there are many items (setting items) to be set, such as the contents of the schedule and the type of each lighting fixture. For example, if schedule control as shown in FIG. 14 is performed, the start time and end time of each time zone, the light control amount in each time zone, the presence or absence of a fade that smoothly changes the light amount at the time of switching the time zone, etc. In addition, it is necessary to set many setting items such as the date and time, the type of lighting equipment, and the lamp replacement time.

However, in order to reduce the size and cost of a lighting device, particularly a control device that outputs a dimming signal to a lighting fixture, it is necessary to increase the size of a display section for displaying the contents of setting items and setting values. It is not possible to use a small and inexpensive liquid crystal display or a so-called 7-segment LED display to display setting values and the like, so that the display range and the number of display digits are small. This makes the setting operation very troublesome. In addition, the number of setting switches that can be provided in the control device is limited, so that the setting operation becomes more difficult. In addition, if there are many setting items, setting errors are likely to occur.

On the other hand, as an illuminating device which can easily perform a setting operation, there are those disclosed in Japanese Patent Application Laid-Open Nos. 4-138691 and 6-290877. In the conventional device described in the former publication, a plurality of lighting main operating devices 100 managed by a center device S are provided on each floor of a building or the like, as shown in FIG. The light amount of the lighting fixtures 101 provided for each of a plurality of rooms on the floor is controlled according to a preset schedule, and the set values of various setting items including the schedule are downloaded from the center device S. Was to do. On the other hand, the conventional device described in the latter publication has a plurality of lighting loads,
It has a control terminal for controlling the lighting state of each lighting load, and a main operation panel for transmitting data indicating the lighting state of the lighting load connected to the control terminal via a transmission line.

However, all of the conventional devices described in the above publications are often installed in a place away from the lighting space in which the lighting equipment is installed, such as the center device S or the main operation panel. It is inconvenient to perform the work by operating the center device S or the main operation panel at a place away from the illumination space when performing the work or the change work. Since the value once set is rarely changed, it is desirable to reduce the configuration required for the setting operation in order to reduce the size and cost. Further, when the installation location is frequently moved due to a layout change, it is more convenient to have no wiring.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS (Embodiment 1) The embodiment described below has a configuration shown in a block diagram in FIG. 1 and is installed in a middle- or large-scale store such as a supermarket. In the store, there are four zones, for example, a grocery section is a first zone, a display shelf is a second zone, a special sale section is a third zone, and a cashier counter is a fourth zone. Are used for controlling the light amount (light control) of the lighting fixtures 2 for each zone.

The illuminating device shown in FIG. 1 has a configuration in which a plurality of luminaires 2 are connected to a main controller 1 via a dimming signal line Lt. The dimming signal lines Lt are provided in four systems (one or more systems), and the dimming signal lines Lt of each system are provided.
Are connected to the luminaires 2 installed in the first to fourth zones, respectively, and output a dimming signal for each dimming signal line Lt so that control can be performed for each system (for each zone). .

The lighting fixture 2 has a lighting device 21 using an inverter circuit, and converts AC power supplied from the commercial power supply AC to the lighting device 21 into high frequency power to turn on a lamp 22 as a light source. Here, a high frequency dedicated lamp (a fluorescent lamp for high frequency lighting) is used as the lamp 22, but other fluorescent lamps and incandescent lamps may be used. The lighting device 21 also functions as a dimmer that receives a dimming signal transmitted via the dimming signal line Lt and adjusts the light output of the lamp 22. The dimming signal includes a pulse width modulation signal (P
WM signal), and the light intensity is instructed by the duty ratio. Further, the light control amount can be changed continuously.

The dimming signal to be given to the lighting fixture 2 is generated in the main controller 1. The main control device 1 includes a control unit 10 having a microcomputer as a main configuration. The control unit 10 includes an operation unit 12 serving as various setting units (predetermined time setting unit and light intensity setting unit) including a switch group, which will be described later. Timer part 1
Then, the control unit 3 determines the light control amount based on the instruction from the control unit 3 and supplies the light control amount to the light control signal output unit 11 to transmit a light control signal to the light control signal line Lt. The main operation of the control unit 10 will be described later.

The operation unit 12 is constituted by using a plurality of switches which can be pressed, such as a tact switch and a rubber switch, and has keys K1 to K1 arranged on the front surface of the housing of the main controller 1 as shown in FIG. K17, each key K1 ...
When the button is pressed, the control unit 10 performs a setting process of setting items, which will be described later. Further, the display unit 14 is configured using a liquid crystal display, and displays a message or the like using pictures and characters in order to allow the operator to perform the setting operation of the setting items in an interactive manner. Further, the display unit 14 is also provided with two display lamps 14a and 14b composed of light emitting diodes for displaying the elapse of the lamp replacement time and the operation state.

The timer section 13 includes a clock section 13a as a time counting means for counting the current time and a lighting time counting section 13b as a lighting time counting means for counting the accumulated lighting time. Here, in this embodiment, the lighting time accumulation method can be selected from the following three methods. That is, a method of accumulating the elapsed time after the power is turned on (assuming that the lamp 22 is continuously turned on after the power is turned on (hereinafter, referred to as a “power synchronization method”), and turning on / off the external contact connected to the main controller 1. A method of accumulating the elapsed time in which the external contact turns on the lamp 22 (on or off) on the assumption that the lamp 22 is turned on and off in response to the turning off (hereinafter referred to as “external contact method”). A method of accumulating the elapsed time in which the external input is in the state of turning on the lamp 22 on the assumption that the lamp 22 blinks in response to an input signal (external input) given to the main control device 1 (hereinafter, “external input method”) ”). The cumulative lighting time measured by the lighting time counting unit 13b is output to the control unit 10 at regular intervals (for example, every hour) and is also displayed on the display unit 14. In addition, the clock unit 13a can set a time zone for controlling the lighting equipment 2 as a schedule, and has a function of notifying the control unit 10 of the start and end of the time zone.

Main controller 1 includes a power supply section 15 that outputs a voltage necessary for the operation of the internal circuit using a commercial power supply AC as a power supply. The power supply unit 15 is configured to supply the control unit 10 with a DC constant voltage of the operating voltage of the microcomputer (for example, 5 volts). The main control device 1 also includes a storage unit (having a RAM or an EEPROM backed up by a battery or the like) 16 as a storage unit for storing various set values and the above-described cumulative lighting time at the time of a power failure. At times, the control unit 10 can restore the operation by reading these values from the storage unit 16. A reset key K2 is provided on the front surface of the housing. When the reset key K2 is depressed when the lamp 22 is replaced, the counting of the cumulative lighting time in the lighting time timer 13b is reset and controlled according to an instruction from the operation unit 12. In the section 10, a dimming correction value described later is reset. Further, a forced lighting key K1 is provided on the front surface of the housing, and when the forced lighting key K1 is pressed to light the inside of the store for a reason such as an event, for example, the control unit 10 is operated by an instruction from the operation unit 12. The lighting control can be temporarily released and the lighting fixture 2 can be fully lit (rated lighting).

In the present embodiment, when the power is turned on, the main controller 1 starts operation, performs initial illuminance correction control described later, and transmits a light control signal of a preset light control amount to a time zone (that is, The schedule control given to the lighting fixtures 2 is performed according to the above-mentioned schedule). Prior to this, it is necessary to set values for a plurality of types of setting items necessary for the initial illuminance correction control and the schedule control. Here, a plurality of types of setting items include a date (year / month / day), a time (current time), a fade type (early or late), and a lamp type (high frequency dedicated lamp, a normal high frequency lamp) as shown in FIG. Fluorescent lamp, incandescent lamp, etc.), lamp replacement time,
Lighting time accumulation method (power supply synchronization method, external contact method or external input method), dimming set value (dimming amount), presence / absence of initial illuminance correction control, presence / absence of fade at time zone switching, time zone start time (predetermined Time), time zone end time (predetermined time), scenes assigned to time zones, and the like. Note that a scene indicates a state (lighting environment) in which light control is performed by a light control set value (light control amount).

For example, as shown in FIG. 4, the time zone start time is set to 9:50, the light fades in early to the dimming setting value of 100 [%] (rated lighting), and the time zone end time 18
Immediately before 1:30, dimming control is performed with the dimming output value calculated from the dimming set value and the illuminance correction value, and a dimming set value of 0 [%] is set at 18:30, the end time of the time zone. Assuming a case where schedule control such as fading out earlier is performed, each value shown in the column of the pattern P1 in FIG. In this case, in the scene S1, the light control setting value is set to 100 [%]. Also, by setting the same value for the time zone start time and the time zone end time, the control unit 10 does not execute the schedule control of the time zone. Although a detailed description is omitted, the setting operation of the values of the above setting items is performed by pressing the keys K3... Of the operation unit 12 according to the guidance displayed on the display unit 14 when the control unit 10 is set to the setting mode. It is done by doing.

Further, the minimum value of the light control amount and the value of the lamp replacement time are automatically set according to the value set in the setting item of the lamp type. For example, when the value A is set in the setting item of the lamp type, the lower limit when the initial illuminance correction control is performed is set to 40%, and when the initial illuminance correction control is not performed, the lower limit is set to 25%. , The lamp replacement time is automatically set to 7500 hours, thereby simplifying the operation. However, the lamp replacement time may be arbitrarily set by the operator.

Next, a description will be given of how the control unit 10 determines the amount of light control. In the present embodiment, as described above, the light amount of the lighting fixture 2 is determined by the deterioration of the lamp 22 and the lighting fixture 2.
By taking into account the fact that the light intensity of the lighting fixture 2 elapses over time by taking into account that the light intensity of the lighting fixture 2 is automatically corrected in accordance with the lighting time in consideration of the fact that the light intensity of the lighting fixture 2 is reduced in accordance with the lighting time, taking into account that the light quantity of the lighting fixture 2 It is controlled to change with. Note that the relationship between the cumulative lighting time and the illuminance correction value experimentally obtained in advance for each lamp type (see FIG. 13) is stored in the storage unit 16 as an illuminance correction table.
This relationship is set so as to cancel the decrease in the light amount of the lighting fixture 2 with the elapse of the cumulative lighting time. That is, when the light amount of the lighting fixture 2 immediately after the power is turned on is set to 100%,
Assuming that the amount of light near the end of the life of the lamp 22 is about 70%, the illuminance correction value is set to 70% immediately after the power is turned on, and is set to 100% near the end of the life of the lamp 22. However, the illuminance correction value is not provided as a continuous value, but is provided at appropriate intervals of the cumulative lighting time. That is, as is clear from FIG. 13, since the rate of change of the illuminance correction value is relatively large during the period in which the accumulated lighting time is short, a short time interval (for example, every hour when the counted time is output from the lighting time timer 13b). ), The change rate of the illuminance correction value decreases as the lighting time increases, so that a long time interval (for example, every several tens to several hundred hours)
Is used to set the illuminance correction value.

The correction of the amount of light control according to the cumulative lighting time is performed by the illuminance correction unit 10 serving as illuminance correction means provided in the control unit 10.
a. The illuminance correction unit 10a selects an illuminance correction value from the illuminance correction table according to the cumulative lighting time output from the lighting time timer 13b at regular intervals, and adjusts the dimming amount (dimming) stored in the storage unit 16. Set value). Assuming that the corrected dimming light amount is the dimming output value, the dimming output value = the dimming set value × the illuminance correction value. For example, in the period where the illuminance correction value is 70%, the dimming set value is 80%. , 5
If it is 0%, the dimming output values are 56% and 3%, respectively.
5%. Further, the control unit 10 checks the dimming output value obtained by the above calculation with a table for pulse width modulation, converts the dimming output value into pulse width modulation data, and outputs the data to the dimming signal output unit 11. I do. Then, the light control signal output unit 11 sends out a light control signal based on the light control output value to the light control signal line Lt. The above-described arithmetic operation of the dimming output value is performed independently for each system in the illuminance correction unit 10a, and the dimming signal output unit 11 performs dimming for each dimming signal line Lt corresponding to each system. Output a signal.

By the way, in order to perform the above-described schedule control, it is necessary to set values for a very large number of setting items, and the setting operation is very troublesome, and setting errors easily occur. Therefore, in the present invention, a plurality of sets of setting values (this value is called a “basic value”) for the plurality of types of setting items necessary for performing a predetermined schedule control are stored in advance in the storage unit 16 as a basic value group. In addition, one basic value group is selected from a plurality of basic value groups stored in the storage unit 16 after the installation of the lighting device, and the basic values constituting the selected basic value group are set to corresponding setting items. So that
This facilitates the setting work of the setting items and prevents setting mistakes.

For example, the four types of patterns P shown in FIG.
1 to P4 each represent a basic value group. When any one of the patterns P1 to P4 is selected, each basic value of the selected pattern P1 to P4 is set as a setting value of a corresponding setting item. . Here, regarding the pattern of the basic value group, if the store where the lighting device of the present embodiment is installed is known in advance, the lighting device is actually operated in the store or a space equivalent thereto. The set value (basic value) may be determined, and if the recommended store space and the space condition of the store at the installation location can be grasped, the set value (basic value) can be determined by a conventionally known lighting design. it can.

Next, after the installation of the main controller 1 and the lighting fixtures 2 and the wiring of the dimming signal lines Lt and the power supply lines are completed, one of the plurality of basic value groups stored in the storage unit 16 is selected.
The procedure for selecting and setting one will be described. After the main controller 1 is turned on, a key K5 for selecting a basic value group provided on the front surface of the housing is pressed to operate the operation unit 12.
, The pressing operation of the key K5 is detected, and the control unit 10 selects one of the four basic value group patterns P1 to P4 in accordance with the detection signal from the operation unit 12 and displays it on the display unit 14. The operator repeatedly presses the key K5 until the desired basic value group patterns P1 to P4 are displayed on the display unit 14, and the desired basic value group patterns P1 to P4 are displayed on the display unit 14.
Key K3 to confirm the selection in the state displayed in
Is pressed, data indicating the selected patterns P1 to P4 is output from the operation unit 12 to the control unit 10. Upon receiving the data, the control unit 10 reads the selected basic value group patterns P1 to P4 from the storage unit 16, sets each basic value included in the read basic value group to a corresponding setting item, and stores it in the storage unit. 16 is stored. After this point, the control unit 10 performs dimming control (schedule control and initial illuminance correction control) based on the basic values stored in the storage unit 16. The control unit 10 operates only when the key K5 is continuously pressed for a predetermined time (for example, several seconds) so that the selection of the basic value group is not switched when the key K5 is erroneously operated after the operation. The selection process of the basic value group may be performed. In the basic value group selection mode, an indicator lamp 14a provided in the display unit 14 is provided.
Flashes to notify the operator, and when the key K3 is pressed, the indicator lamp 14b flashes and notifies the operator the number of times of the determined basic value group pattern number. However, the buzzer may be sounded by the number of times of the number of the selected pattern to notify by sound.

As described above, in the present embodiment, the basic value group selection / setting means including the control unit 10 and the operation unit 12 selects from among a plurality of basic value groups prepared in advance for a plurality of types of setting items. Since the setting operation is completed by selecting and setting, the setting operation of the setting item can be easily performed and the setting error can be prevented.

By the way, in this embodiment, the patterns P1 to P4 of the basic value group can be directly selected by pressing the key K5 for selecting the basic value group. When the keys K14, K15) are pressed, the control unit 10 sets the pattern P of the basic value group.
If the process of selecting 1 to P4 is executed, the key K5 for selecting and setting the basic value group is shared with another key, thereby providing an advantage that the cost can be reduced and the size can be reduced by reducing the number of parts. Even in this case, if the key is pressed while a specific screen is displayed on the display unit 14, or if the key is pressed for a predetermined time (for example, several seconds).
By setting the control unit 10 to perform the selection process of the basic value group only when the push operation is performed continuously, it is possible to prevent a setting error in which the selection of the basic value group is inadvertently switched. Further, the control unit 10 shifts to the basic value group selection mode by continuously pressing the basic value group selection key K5 or a common key with another key, and presses any key in the basic value group selection mode. Thus, the control unit 10 may perform the selection process of the basic value group. Furthermore, the control unit 10 may perform a selection process of a basic value group by simultaneously pressing a plurality of keys. For example, when the keys K6 and K7 are simultaneously pressed, the pattern P1, the keys K6 and K8 are set. When the push operations are performed at the same time, the pattern P2 may be used. Alternatively, the control unit 10 shifts to a basic value group selection mode by simultaneously pressing a plurality of keys, and by pressing any key in the basic value group selection mode, the control unit 10 performs a basic value group selection process. May be performed. Further, by turning on the power while pressing the key K5 for selecting the basic value group or a key shared with the other, the patterns P1 to P4 of the basic value group can be selected, or the key K5 or the other for selecting can be selected. The control unit 10 may shift to the basic value group selection mode by the continuous pressing operation of the common key. As described above, various methods are conceivable for the selection operation of the patterns P1 to P4 of the basic value group. However, a method that can be easily selected may be inadvertently changed and cause a problem in the dimming control operation. It is desirable to select a method in which the selection operation itself is easy as in the above various methods, but is not carelessly selected. Note that, when a key operation for changing the basic value group is performed, a warning display may be performed by the control unit 10.

By the way, among the plural kinds of setting items, related setting items may be sorted and grouped, and a basic value group may be prepared for each group. For example, FIG.
As shown in (a), as a first group, a plurality of patterns PA1 to PA4 each consisting of a set (basic value group) of basic values for setting items (lamp type, lamp replacement time, scene contents, etc.) for each system. It is stored in the storage unit 16 in advance, and is set by selecting from any of the above-described patterns PA1 to PA4 for each system (zone) as shown in FIG. Note that the alphabet “Y”, which is added to the end of the dimming setting value in each of the scenes S1 to S4 in FIG.
In “N”, “Y” indicates that the initial illuminance correction control is performed, and “N” indicates that the initial illuminance correction control is not performed.

As shown in FIG. 6A, a set of basic values (basic values) for the setting items (time zone start time, time zone end time, scenes to be output, etc.) for each time zone is formed as a second group. Group) PB1 to PB6
Are stored in the storage unit 16 in advance, for example, as shown in FIG.
As shown in FIG. 7, one of the patterns PB1 to PB6 is selected and set for each day of the week on a weekly basis. here,
As shown in FIG. 6C, among the patterns PB1 to PB6, those frequently used (for example, PB1, PB4, PB
