Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lighting control system for controlling the illuminance of a desk surface.

[0002]

2. Description of the Related Art In a room such as an office where desk work is mainly performed, it is necessary to control ceiling lighting so that the illuminance on the desk surface becomes optimum. In this case, an illuminance sensor is installed on the top of the desk,
It is desirable to control the ceiling lighting by directly measuring the illuminance on the desk surface. However, newly providing an illuminance sensor on the desk top surface requires complicated signal wiring work and increases costs. Further, if the desk is rearranged, there is a problem that the wiring work must be newly redone. Therefore, the conventional lighting control system measures the illuminance on the ceiling surface, estimates the illuminance on the desk surface based on the illuminance on the ceiling surface, and controls the ceiling lighting based on the estimated value.

[0003]

However, in the above-mentioned conventional lighting control system, since the illuminance on the desk surface is inferred from the illuminance on the ceiling surface, the accurate illuminance on the desk surface cannot be obtained. For example, when a task light is used together, the ceiling illuminance is brighter than necessary because the illuminance on the desk top is a predetermined illuminance, but the illuminance on the desk top is inferred from the illuminance on the ceiling. As a result, useless lighting energy is consumed. As described above, when the task light is used together, it is impossible to obtain an accurate illuminance on the desk surface by the conventional analogy method system. Further, in this case, since the ceiling lighting becomes brighter than necessary, it is difficult to concentrate on the desk work, and a comfortable visual environment for the worker cannot be obtained. The present invention has been made in view of the above circumstances, accurately measuring the illuminance on the desk surface,
An object of the present invention is to provide a lighting control system capable of performing lighting control, thereby achieving a comfortable visual environment and energy saving at the same time.

[0004]

Ceiling lighting fixture, a lighting fixture dimming control panel for controlling the illuminance of the ceiling lighting fixture, an illuminance sensor provided in the mouse,
A LAN connecting the personal computer and the lighting fixture dimming control panel, and dimming control information to the lighting fixture dimming control panel via the LAN based on the illuminance measurement value connected to the LAN and measured by the illuminance sensor And an illuminance data totaling server for transmitting.

In this illumination control system, the dimming control information from the illuminance data collection server is transmitted to the luminaire dimming control panel based on the illuminance measurement value measured by the illuminance sensor. Therefore, even when used in combination with a task light, the illuminance on the desk surface can be accurately measured, and accurate lighting control of the ceiling lighting fixture can be performed. Also, the ceiling lighting will not be brighter than necessary.

The illumination control system according to a second aspect is the illumination control system according to the first aspect, wherein the illuminance data collection server stores the illuminance set value input from the personal computer, and the illuminance set value and the illuminance set value. It is characterized in that the dimming control information is calculated by comparing with an illuminance measurement value measured by an illuminance sensor.

In this illumination control system, the illuminance data totaling server calculates the dimming control information by comparing the illuminance set value with the illuminance measurement value. Therefore, the predetermined illuminance can be set according to the operator's preference.

A lighting control system according to claim 3 is the lighting control system according to claim 1 or 2, further comprising a task light for illuminating a desk on which a personal computer is mounted, in addition to the ceiling lighting fixture. A data totaling server transmits the individual dimming control information for each of the ceiling lighting fixture and the task light to the lighting fixture dimming control panel, and the lighting fixture dimming control panel causes the ceiling lighting fixture. And controlling the illuminance of the task light individually.

In this lighting control system, each of the ceiling lighting fixture and the task light is set to the operator's liking to obtain a predetermined illuminance, and the operator's favorite visual environment (for example, the task light is brightened and the ceiling lighting is lit. A visual environment that darkens the fixture,
Or the opposite visual environment) can be set freely.

BEST MODE FOR CARRYING OUT THE INVENTION Preferred embodiments of an illumination control system according to the present invention will be described in detail below with reference to the drawings. 1 is a conceptual diagram of a lighting control system according to the present invention, and FIG. 2 is a plan view of a mouse with an illuminance sensor used in the lighting control system shown in FIG.

A plurality of desks (not shown) are placed in a room such as an office, and a personal computer 1 is placed on each desk. The personal computer 1
At least the display device 3 and the mouse 5 as a pointing device are provided. The mouse 5 may be either a wired type or a wireless type. These personal computers 1 are connected to each other via a LAN (Local
Area Network) 7 is used to connect and receive information.

A plurality of ceiling lighting devices 9 are attached to the ceiling of the living room in which the personal computer 1 is installed.
These ceiling lighting fixtures 9 are connected to a lighting fixture dimming control panel 11. The lighting fixture dimming control panel 11 enables control of dimming each ceiling lighting fixture 9 to a desired illuminance based on dimming control information described later. The lighting device dimming control panel 11 is connected to the LAN 7.

The mouse 5 of each personal computer 1 or the predetermined personal computer 1 is provided with an illuminance sensor 13 shown in FIG. Illuminance sensor 13
Can measure the illuminance on the top surface of the desk on which the personal computer 1 is placed. Personal computer 1
Can send the measured illuminance value obtained by the illuminance sensor 13 to the LAN 7.

The illuminance data totaling server 15 is connected to the LAN 7.
Are connected. As the illuminance data collection server 15,
A personal computer equivalent to the personal computer 1 described above can be used. The illuminance data totaling server 15 can receive the illuminance measurement value transmitted from each personal computer 1 via the LAN 7. Then, the illuminance data totaling server 15
Transmits the dimming control information to the lighting fixture dimming control panel 11 via the LAN 7 based on the received illuminance measurement value.

The illuminance data totaling server 15 stores a preset illuminance set value on the desk surface set in advance.
This illuminance setting value is fixedly stored in the ROM,
Alternatively, it may be one by an input described later. The illuminance data totaling server 15 sends the dimming control information such that the illuminance measurement value measured by the illuminance sensor 13 becomes equal to the preset illuminance set value. This dimming control information can be obtained by feedback control, for example. Also, the illuminance data totaling server 15 can individually send the dimming control information to the ceiling lighting fixture 9 corresponding to the position of the desk on which the mouse 5 is placed.

Therefore, for example, if the task light of a specific desk is turned on, the illuminance on the desk top becomes high,
The dimming is automatically adjusted so that the illuminance of the ceiling lighting fixture 9 corresponding to the specific desk is lowered correspondingly to the predetermined illuminance set value. On the contrary, if the task light of a specific desk is turned off, the illuminance on the top surface of the desk becomes low. Therefore, the ceiling lighting corresponding to the specific desk is set to the predetermined illuminance setting value. The light is automatically adjusted so that the illuminance of the device 9 becomes high.

According to the illumination control system thus configured, the dimming control information from the illuminance data collecting server 15 is transmitted to the luminaire dimming control panel 11 based on the illuminance measurement value measured by the illuminance sensor 13. Therefore, even when used in combination with a task light, the illuminance on the desk surface is accurately measured, and accurate lighting control of the ceiling lighting fixture 9 is possible. Moreover, the ceiling lighting does not become brighter than necessary. As a result, a comfortable visual environment and energy saving can be achieved at the same time.

Next, a modified example 1 of the illumination control system according to the present invention will be described. In addition, although this modification is not shown, the same members as those shown in FIGS. 1 and 2 are designated by the same reference numerals. In the illumination control system according to the first modification, the illuminance data collection server 15 stores the illuminance set value input from the personal computer 1, and compares the illuminance set value with the illuminance measured value measured by the illuminance sensor 13. And calculates the dimming control information. In other words, the operator can freely set the desk illuminance via the personal computer 1. Other configurations are the same as those of the illumination control system of the above-described embodiment. According to the illumination control system according to the first modification, the illuminance data totaling server 15 calculates the dimming control information by comparing the illuminance set value with the illuminance measurement value. Can be realized.

Next, a modified example 2 of the illumination control system according to the present invention will be described. FIG. 3 is a detailed block diagram of essential parts showing a second modification of the illumination control system shown in FIG.

The illumination control system according to the second modification is
In addition to the ceiling lighting device 9, a task light 21 for illuminating a desk on which the personal computer 1 is placed is provided. The illuminance data totaling server 15 has an illuminance set value storage unit 23 that stores the illuminance set value. The illuminance set value storage unit 23 further includes a ceiling illumination storage unit 25 that stores the illuminance set value of the ceiling lighting fixture 9, and a task light storage unit 27 that stores the illuminance set value of the task light 21. .

Further, the illuminance data totaling server 15 has an illuminance measurement value storage unit 29 for storing the illuminance measurement value, a comparing means 31 for comparing the set value and the measured value, and a dimming operation based on the comparison result by the comparing means 31. The control information calculation part 33 which calculates control information is provided. In addition, lighting equipment dimming control panel 11
Is a ceiling lighting dimming unit 35 for controlling the ceiling lighting fixture 9,
The task light control section 37 controls the task light 21.

In the lighting control system according to the second modification, the illuminance of the ceiling lighting fixture 9 and the task light 21 can be set by each personal computer 1. The illuminance set values of the ceiling lighting fixture 9 and the task light 21 set via each personal computer 1 are set via the LAN 7 to the illuminance data totaling server 15
The illuminance measurement value storage unit 29 is stored. The illuminance data totaling server 15 transmits individual dimming control information for the ceiling lighting fixture 9 and the task light 21 to the lighting fixture dimming control panel 11. The lighting fixture dimming control panel 11 individually controls the illuminance of the ceiling lighting fixture 9 and the task light 21. The illuminance measurement value storage unit 2
The illuminance setting value of the desk top surface described in the first modification is also stored in 9. That is, the illuminance measurement value storage unit 29 stores the illuminance set value of the desk surface, the illuminance set value of the ceiling lighting fixture 9, and the illuminance set value of the task light 21.

The illumination control system according to the second modification is
Dimming is performed in three modes: an automatic mode that is the first mode, a priority mode that is the second mode, and a manual mode that is the third mode. This mode can be performed by calling the dimming setting screen of each personal computer 1.

In the automatic mode which is the first mode, as described in the modification 1, when the illuminance set value of the desk surface is inputted from the personal computer 1, the illuminance data totaling server 1
5 stores this illuminance set value, and the ceiling luminaire 9 is automatically controlled so that the illuminance measurement value measured by the illuminance sensor 13 matches this illuminance set value.

The second priority mode is divided into a case where the ceiling lighting fixture 9 is preferentially controlled and a case where the task light 21 is preferentially controlled. When the ceiling lighting fixture 9 is prioritized, the desired illuminance of the ceiling lighting fixture 9 is input to the personal computer 1 as the illuminance setting value. As a result, the task light 21 is automatically dimmed so that the desk top surface has a predetermined illuminance. On the other hand, when the task light 21 is prioritized, the desired illuminance of the task light 21 is input to the personal computer 1 as the illuminance setting value. Accordingly, the ceiling lighting fixture 9 is automatically dimmed so that the desk top surface has a predetermined illuminance.

In the third manual mode, the ceiling luminaire 9 and the task light 21 can be set to any illuminance. Therefore, in this mode, the automatic light control operation for matching the desk top surface with the illuminance setting value is canceled.

The operation flow of the lighting control system according to the second modification, for example, in the automatic mode will be described. FIG. 4 is a flowchart illustrating the operation of the second modification. After turning on the power of the personal computer 1, when setting / changing the illuminance setting value, call the illuminance setting screen (st
1). Here, in the priority mode and the manual mode, the desk illuminance setting value, the ceiling illumination setting value, and the task light setting value are appropriately input (st3, st5) and stored in the illuminance measurement value storage unit 29 ( st7). It should be noted that, since the present description is the automatic mode, it is assumed that the desk top surface illuminance set value is set in advance, and the ceiling light set value, the task light set value, or both are not input.

Next, the illuminance sensor 13 provided on the mouse 5
The illuminance on the desk top is measured by (st9). When the illuminance measurement is completed, the comparing unit 31 compares and determines the illuminance measurement value and the illuminance set value (st15). On the other hand, when the illuminance measurement cannot be performed while the mouse 5 is in use, the measurement is performed again after a predetermined time (for example, 5 minutes). This remeasurement is repeated until the measurement is completed. The illuminance sensor 13 may be connected to the personal computer by itself without being built in the mouse 5.

The comparing means 31 judges whether the measured illuminance value is within the range of the illuminance set value (st17), and if it is within the range, the processing is terminated. On the other hand, when the illuminance measurement value is not within the range of the illuminance set value, the control information calculation unit 33 determines that the illuminance sensor 13
The dimming control information is calculated so that the illuminance measurement value measured by the same as the preset illuminance setting value is calculated, and the dimming control information is transmitted to the lighting fixture dimming control panel 11 via the LAN 7 (st19). . The lighting fixture dimming control panel 11 performs dimming control of the ceiling lighting fixture 9 based on this dimming control information.

In this operation flow, the processing is terminated after transmitting the dimming control information once, but the processing flow shown by the chain double-dashed line in FIG. The dimming process may be performed at intervals of one hour.

According to the lighting control system of the second modification, the illuminance data totaling server 15 transmits the individual dimming control information of the ceiling lighting fixture 9 and the task light 21 to the lighting fixture dimming control panel 11. Since the lighting fixture dimming control panel 11 individually controls the illuminance of the ceiling lighting fixture 9 and the task light 21, the operator's favorite visual environment can be freely realized.

Since the illuminance data totaling server that transmits the dimming control information to the dimming control panel is connected via LAN, the illuminance data totaling server transmits the dimming control information based on the illuminance measurement value measured by the illuminance sensor. It can be transmitted to the panel, and even when used in combination with a task light, the illuminance on the desk surface can be accurately measured, and lighting control can be performed without making the ceiling lighting unnecessarily bright. As a result, a comfortable visual environment and energy saving can be achieved at the same time.

According to the illumination control system of the second aspect, the illuminance data totaling server calculates the dimming control information by comparing the illuminance set value with the illuminance measurement value, so that the illuminance desired by the operator can be determined. Can be realized.

According to the lighting control system of the third aspect, the illuminance data totaling server transmits the individual dimming control information of the ceiling lighting fixture and the task light to the lighting fixture dimming control panel, and the lighting fixture dimming control is performed. Since the control panel individually controls the illuminance of the ceiling lighting equipment and the task light, it is possible to freely realize the visual environment desired by the operator.
