Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention has a plurality of luminaires each including a communication section, a lighting load, and a control section for controlling the lighting load. Signal lines are connected to each communication section so as to be able to communicate with each other. The lighting device to be used.

[0002]

2. Description of the Related Art Conventionally, a lighting apparatus having a plurality of luminaires including a communication section, a lighting load, and a control section for controlling the lighting load, and a signal line connected to each communication section so as to be able to communicate with each other. Have been proposed.

[0003] For example, Japanese Patent Application Laid-Open No. 9-35875 discloses that a remote control operation switch is used as a setting device for group control or pattern control, and its operation is set for each control terminal device. The group number or pattern number to which the own station belongs is stored, so that the group control or pattern control setting work can be performed by operating the remote control operation switch toward the lighting equipment having a built-in control terminal. A lighting control system is disclosed.

Japanese Patent Application Laid-Open No. 9-35876 discloses that
Interposed between multiple systems of lighting control systems with lighting loads,
Lighting relays that enable the transmission of lighting control signals between the lighting control systems so that the signal lines can be apparently extended with little change to the specifications of each lighting control system. Vessels etc. are described.

[0005]

However, in the above-mentioned conventional lighting control system, when a lighting equipment (control terminal and lighting equipment in the above publication) is newly added to the existing system, the remote control is taken out and set. The operation needs to be performed again.

Further, in a lighting device such as the above-mentioned lighting control system, which does not have a master unit for centrally managing the plurality of lighting devices and is constituted by a plurality of lighting devices, various setting items are associated with a group number. If the group number is changed to another group number in such a case, how to set the information of each setting item for the other group number becomes a problem. In order to cope with this problem, if a table including, for example, various group numbers and information on each setting item for each of them is stored in the memory inside the remote controller, the storage capacity increases and the price increases. . Further, the information of each setting item is once taken into the remote controller from the lighting fixture already belonging to the above another group number, and the information taken through this remote controller is copied to the lighting fixture changed to the above another group number. In such a case, it takes time for such copying.

In the case of a luminaire in which a plurality of groups can be set, the transition control of the illumination between the groups becomes complicated. In this transition control, a so-called post-operation priority method may be adopted. However, in recent years, for example, automation such as automatic lighting by a human sensor has been advanced, and operation has been complicated due to high functionality, so that it is difficult to comfortably control a lighting device in transition control with priority given to post-operation. Is coming.

For example, each lighting fixture has a human sensor,
There are groups A and B, and the lighting equipment belonging to both of them is R, and the lighting equipment R is 100% as group A.
Assuming that a command to turn on the lighting load at 50% is issued to the group B while the lighting fixture R is turned on, the lighting fixture R is turned on at 50%. Thereafter, when there is no person in the area of the group B while the person is still in the area of the group A, the human sensor of each lighting device of the group B causes the human sensor of each lighting fixture of the group B to elapse after a predetermined holding time for maintaining the lighting state. Since the lighting device is turned off, the lighting devices belonging to the group B excluding the lighting device R are turned off. As a result, the lighting equipment R is turned on at 50%, the lighting equipment belonging to the group A excluding the lighting equipment R is turned on at 100%, and the lighting equipment belonging to the group B excluding the lighting equipment R is turned off. As described above, in the transition control based on the post-operation priority, 50% of the luminaires R belonging to the group A where a person is still present despite the fact that the luminaires are grouped based on the required illuminance. Is maintained, and it is no longer possible to secure the illuminance originally required for the area of the group A. In such a case, it is desirable that the lighting fixture R be turned on at 100%.

As a countermeasure against this, when the lighting fixtures R are kept in the states of the groups A and B, and the lighting fixtures belonging to the group B excluding the lighting fixtures R are turned off from the same state as above, the lighting fixtures R become 100%. When the lighting device is configured to be turned on, a problem occurs in another transition state. That is, as described above, the lighting fixture R is group A and 1
Assuming that a command to turn on the lighting load at 50% is issued to the group B when the lighting is turned on at 00%, the lighting fixture R is turned on at 50%. At this time, the lighting fixture R maintains the lighting state (100%) when belonging to the group A. Then, while the lighting fixture R holds the lighting state (100%), for example,
There are no more people in the area of Group A, then Group B
If there are no more people in the area, first, the lighting fixture R
Lighting fixtures belonging to group A excluding are turned off,
The lighting equipment belonging to the group B excluding the lighting equipment R is turned off. At this time, the lighting equipment R is turned on at 100%. Furthermore, if the number of groups to which the lighting fixture R belongs increases, the processing in the lighting fixture R becomes more complicated.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a lighting device that can be easily set.
