Abstract

PURPOSE:To simply set the optimum illuminance for each work position by providing multiple receptacles and illuminance operation units generating and sending the dimming data. CONSTITUTION:When an illuminance operation unit 7 is connected to a receptacle 6 on a floor and the channel number of a lighting load 4 to be set on illuminance is specified by the CH No switch of the illuminance operation unit 7 and a lighting switch is turned on, a signal indicating that the lighting load 4 with that channel number is to be lighted is sent from the illuminance operation unit 7 to a transmission signal line 5. Upon receiving this signal, a main operation panel 1 lights the lighting load 4 with the specified channel number. After lighting, the illuminance is measured by an illuminance meter 8 and an illuminance sensor 9. As a result, when the illuminance-up or down is required to obtain the optimum illuminance, an illuminance-up switch UP or an illuminance-down switch DOWN is turned on. The lighting load 4 can be thereby lighted at the desired optimum illuminance.

Description

[Detailed Description of the Invention] [Industrial Application Field] 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 use of office floors, etc. Regarding illuminance control system.

[Prior Art] Conventionally, lighting systems in offices, theaters, etc. have a main operation panel and signal terminals connected to the main operation panel via transmission lines, and from the main operation panel 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.

[Issue 8 to be solved by the invention] However, in such a 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 sent to the main operation panel instead of on-site. 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 view of the problems with conventional systems, it is an object of the present invention to easily set the optimum illuminance according to the purpose of the office floor, etc., for each work place, for example, directly on-site while checking the illuminance meter. An object of the present invention is to provide an appropriate illuminance control system that can set the optimum illuminance by operating the system.

[Means and effects for solving the problem] In order to achieve the above object, the present invention provides a main operation panel, a terminal device connected to the main operation panel via a transmission line, and a terminal device. In an appropriate illuminance control system comprising a lighting fixture connected to the terminal device and dimmable by a dimming signal from the terminal device, a single or A plurality of outlets arranged in units of areas constituted by a plurality of lighting fixtures, and connected to the outlets, generate dimming data to be sent to the terminal device in order to adjust the illuminance of the lighting fixture to a desired illuminance. The illuminance control device is characterized in that it is equipped with an illuminance control device that sends out the illuminance.

According to the above configuration, the illuminance can be easily set by connecting the illuminance control device to the outlet provided in each area of a suitable floor. For example, by setting the channel number of a lighting fixture on the floor using an illuminance control device and instructing it to turn on, the lighting fixture is turned on. Then, while measuring the illuminance with the illuminance meter, the illuminance can be easily set to a desired illuminance value by instructing to increase or decrease the illuminance with the illuminance controller.

Note that the signal from the illuminance control device may be transmitted by wireless transmission, received by a wireless receiver provided at an appropriate position, and sent onto the transmission line.

Further, this wireless receiver may be connected to a transmission line through an outlet.

Furthermore, when increasing the illuminance of a given lighting fixture using the illuminance control device, an upper limit display indicating that the illuminance cannot be increased any further can be displayed to indicate when it is time to replace the lamp of the lighting fixture or when cleaning the lighting fixture. This is useful for maintenance, etc.

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

It is ED.

In addition, among the switch group 13, the switch marked "Lighting" is a switch that instructs lighting of the illuminance load, rcHNo., J is a switch that specifies a channel number for specifying a predetermined lighting load, and rUPJ is a switch that instructs lighting of a lighting load. A switch that instructs to increase the illuminance, rDOWNJ, is a switch that instructs to decrease the illuminance of the lighting load.

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 CH No. of the illuminance controller 7.

Using the switch, the channel number of the lighting load 4 whose illuminance is to be set is specified, and the lighting switch is turned on.

As a result, a signal indicating that the lighting load 4 of the channel number should be turned on is sent from the illuminance controller 7 to the transmission signal line 5. The main operation panel 1 receives this signal and lights up the lighting load 4 of the designated channel number. After the light is turned on, the illuminance is measured using the illuminance meter 8 and the illuminance sensor 9. As a result, if it is necessary to increase or decrease the illuminance in order to obtain the optimum illuminance, the illuminance up switch UP or the illuminance down switch DOWN is turned on. As a result, a signal to increase or decrease the illuminance of the lighting load 4 of the channel is sent from the illuminance controller 7 to the transmission signal line 5. The main operation panel 1 receives this signal and sends dimming data to the terminal 3 to increase or decrease the illuminance of the lighting load 4 of that channel. As a result, the illuminance of the predetermined lighting load is increased or decreased as instructed. .

As described above, the user can operate the illuminance controller 7 while looking at the illumination meter 8, and directly and easily set the lighting load 4 of the channel to be lit at the desired optimum illuminance on site.

According to the first embodiment described above, as the illumination area for which illuminance is to be set becomes smaller, it is necessary to install outlets for connecting the illuminance controller 7 in multiple locations accordingly. Furthermore, the second embodiment also requires a plurality of wireless receivers, leading to an increase in cost. According to the configuration shown in Figure 5, only one wireless receiver is required, and the number of outlets connected to the transmission signal line can be set to one or more within the range where wireless transmission can be performed, so the number of outlets is kept to a minimum. can be suppressed to

[Effects of the Invention] As described above, according to the present invention, the illuminance can be set directly on site using the illuminance controller, and there is no need to go to the main operation panel. Then, it is possible to easily set the desired lighting equipment to the appropriate illuminance, and by setting the appropriate illuminance, it is possible to improve the efficiency of business operations.
