Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to an appropriate illuminance control system, and in particular, an appropriate illuminance control system that can easily set the optimum illuminance according to the purpose of office floors, etc. Regarding illuminance control system.

[Prior Art] Conventionally, lighting systems in offices, theaters, etc. have a main operation panel and a signal terminal connected to the main operation panel via a transmission line, and the main operation panel is connected to each signal terminal. Based on the sent dimming data, there is a system that performs on/off control or dimming control of dimmable lighting fixtures with built-in dimming function connected to each signal terminal, and lighting fixtures connected to the dimmer. It is being The illuminance of lighting fixtures used in such systems gradually decreases over time depending on the luminous flux reduction characteristics of the lamps used in the fixture and the dirt on the fixture, and the rate of luminous flux decline is between 20 and 40%. %. In order to prevent the visual environment from deteriorating due to such a decrease in illuminance, for example, workers regularly measure the illuminance of the place where the lighting equipment is installed using a luminometer, and based on this measurement, the main operation panel etc., the setting values were adjusted manually.

[Problems to be Solved by the Invention] However, in this conventional method, the illuminance of the place where the lighting equipment is installed is periodically measured, and based on the measurement results, the illuminance is determined not on-site but at the main operation panel. It is necessary to adjust the illuminance setting value. Therefore, in order to set an appropriate illuminance, a troublesome illuminance adjustment operation is required, and it is also time-consuming.

In addition, it was inconvenient to use the illumination meter because it had to be carried around every time.

In view of the problems with conventional systems, the purpose of the present invention is to easily set the optimum illuminance according to the purpose of the office floor, etc. for each work place, and to directly set the illuminance at the work site without carrying a separate illuminance meter. The object of the present invention is to provide an appropriate illuminance control system that can be used.

[Means and operations for solving the problem] In order to achieve the above object, the present invention includes a main operation panel, a terminal device connected to the main operation panel via a transmission line, and a terminal device connected to the main operation panel via a transmission line. An appropriate illuminance control system comprising a connected lighting fixture that can be dimmed by a dimming signal from the terminal device, comprising means for setting a desired illuminance, means for detecting the illuminance of the lighting fixture, and the detected illuminance. and means for sending a signal to the main operation panel to instruct the illuminance of the lighting fixture to increase or decrease until the illuminance becomes equal to the desired illuminance.

According to the above configuration, it functions as an illuminance control device that can set the illuminance of the desired lighting equipment directly from the site;
Since the function of an illuminance meter that measures illuminance is integrated into one device, there is no need to carry a separate illuminance meter.

The user can use the illumination meter function to measure the actual illuminance at the site and manually instruct the desired illuminance. In addition, when automatically setting the illuminance, if you set and instruct the desired illuminance, this system will detect the actual illuminance of the lighting equipment and make sure that the actual illuminance at the site is equal to the set desired illuminance. A signal is sent to the main control panel to set the illuminance of the lighting equipment. In response to this, the main operation panel sends a signal to the terminal device in order to set the lighting device to the desired illuminance.

[Example Hereinafter, the present invention will be explained in detail using the drawings.

FIG. 1 shows a schematic configuration of an appropriate illuminance control system according to an embodiment of the present invention. The system in the figure consists of main operation panel 1
, terminal devices 3-1.3-2. connected to this main operation panel 1 via a transmission line 2. . . . A lighting load 4 that is turned on at a predetermined illuminance in response to dimming data from a terminal device, a transmission line 5 having an outlet 6, and an illuminance control device 7 connectable to the outlet of the transmission line 5. We are prepared. The outlet connected to the transmission line 5 is provided in advance at a position suitable for connecting the illuminance controller 7 and setting the illuminance. The illuminance controller 7 includes an illuminance sensor 8, a power switch 9, and a 7-segment LED for displaying the desired illuminance set by the user.
A 7-segment LED II that displays the illuminance of the site measured by the O1 illuminance sensor 8, a numeric keypad 12 for inputting the desired illuminance,
A manual/automatic changeover switch 13 for selecting whether to set the illuminance manually or automatically, a start switch 14 for automatic illuminance setting, an address switch 15 for specifying the address of the terminal, an illuminance up switch 16, and an illuminance down switch 17. , an on/off switch 18 for instructing the lighting equipment to turn on/off.

FIG. 2 is a schematic configuration diagram showing the internal configuration of the illuminance controller 7. As shown in FIG. In this figure, the same numbers as in FIG. 1 indicate the same members. Reference numeral 19 indicates the switch groups 13 to 18 in FIG.

20 is a key power section, 21 is a transmission interface for exchanging signals with the main operation panel 1, 22 is a transmitting/receiving section, 23 is a processing section, 24 is a display output section, 25 is an upper limit display LED, 2
6 is an illuminance sensor input section.

In such a configuration, the illuminance of the lighting load on a certain floor can be set to the optimum value as follows.

First, the illuminance controller 7 is connected to the outlet 6 on the floor. Then, the power to the illuminance controller 7 is turned on, an address is set with the address switch 15, and the on/off switch 18 is turned on. As a result, a signal indicating that the predetermined lighting load 4 should be turned on is sent from the illuminance controller 7 to the transmission line 5. The main operation panel 1 receives this signal and sends a signal to the terminal device 3 to turn on a predetermined lighting load 4. This turns on the lighting load. After the light is turned on, the actual illuminance is measured by the illuminance sensor 8, and the illuminance value is displayed on the illuminance display 11.

On the other hand, the desired illuminance value to be set is input using the numeric keypad 12. The desired illuminance value is displayed on the desired illuminance display 10.

The illumination intensity can be set manually or automatically.

In the case of manual operation, the manual/automatic changeover switch 13 is set to manual. Then, the desired illuminance display 10 and the current measured illuminance display 11 are compared, and if it is darker than the desired illuminance, the illuminance up switch 16 is turned on, and if it is brighter than the desired illuminance, the illuminance down switch 17 is turned on. As a result, a signal instructing to increase or decrease the illuminance is sent from the illuminance controller 7 to the main operation panel 1. In this way, the user can easily set the desired illuminance at the site by simply operating the illuminance up switch 16 or the illuminance down switch 17 while looking at the display 10.11 of the illuminance controller 7.

When setting the illuminance automatically, the manual/automatic changeover switch 13 is set to automatic, and the start switch 14 is turned on. As a result, the processing section of the illuminance control section 7 compares the input desired illuminance value with the actual illuminance value measured by the illuminance sensor 8, and makes sure that the actual illuminance value is equal to the desired illuminance value. A signal instructing to increase or decrease the illuminance is automatically generated and sent to the main operation panel 1. In response to this, the main operation panel 1 sends out No. 1J to increase or decrease the illuminance of a predetermined lighting fixture 4. Then, when the actual measured illuminance value and the desired illuminance value become equal within a predetermined tolerance range, the process ends.

In this embodiment, when the illuminance reaches the upper limit at which it cannot be increased any further, the upper limit display LED 25 is turned on, so that it can be seen that the lamp needs to be replaced or cleaned, and maintenance is easy.

[Effects of the Invention] As explained above, according to the present invention, the function of sending a signal to the main operation panel to set the illuminance and the function of an illuminance meter are combined into one.
Since it is realized with one illuminance control device, the configuration is compact, and the optimal illuminance setting according to the work purpose can be easily set on site without having to carry a separate illuminance meter. By setting the lighting equipment to an appropriate illuminance, it is possible to improve the efficiency of work. Furthermore, since the illuminance control device automatically sends illuminance setting data to match the illuminance of the site to the desired illuminance, the setting operation is very simple.
