Description

  Embodiments described herein relate generally to a lighting control system.

  Conventionally, in a dimming system used for a stage or the like, a method of collectively controlling lighting of the stage or the like with a dimming console is common. For example, dimming control information for controlling the dimmer is generated by the dimming console so that the lighting state produced as stage lighting is obtained. The dimming console transmits the dimming control information to the dimming panel as a DMX signal in a format conforming to the standard of DMX512 (1990) (American Theater Technology Association (USITT) standard), for example.

  The light control panel is equipped with a phase control type dimmer for each lighting fixture, and each dimmer is controlled by the dimming control information from the dimming console. Dimming control is performed on all the luminaires.

  By the way, in order to freely control the lighting in the lighting space on the dimming console, it is necessary to grasp at which position in the lighting space each luminaire to be controlled from the dimming console. For a lighting device such as a halogen device, the position of the lighting device is determined by associating the attachment port of the lifting baton to which the lighting device is mounted with the dimmer in the light control panel in a one-to-one relationship.

  That is, the lifting baton is provided with a plurality of connection terminals (load outlets) connected to the load circuits of the dimmers, and the load lines of the lighting loads are connected to the connection terminals, respectively. The connection terminal of the lifting baton and the dimmer have a one-to-one correspondence, and the position in the illumination space of the attachment port of the lighting fixture corresponding to the connection terminal of the lifting baton is known. It can be grasped which lighting device at which position can be dimmed by controlling which dimmer.

  However, in recent years, dimming lighting control is possible by connecting a 100V commercial power supply and a control line such as DMX with a built-in lighting control means without requiring a load circuit of a dimmer like LED lighting equipment. The number of luminaires has increased. Such a lighting fixture will be arrange | positioned irrespective of a light control device, and can be installed anywhere without depending on the place and number of load outlets. For this reason, about such a lighting fixture, the installation position cannot be specified in association with the dimmer.

  In such a case, it is conceivable that the arrangement position of the lighting fixture is specified using an ID unique to each lighting fixture. That is, the correspondence between the installation position of the lighting baton and the ID of the lighting fixture attached to that position is registered for each lighting fixture at all positions. However, this registration work is extremely complicated. Further, when the light source is at the end of its life, it is only necessary to replace the lamp if it is a halogen lamp device. However, in the case of an LED lighting device, it is often necessary to replace the entire lighting device. is necessary.
