Then, the lighting equipment 7, 7' is attached to the wiring duct body 2.
By attaching plugs (not shown) and contacting the contacts 12a, 12b; 13a, 13b to the parallel conductors 2a, 2b, respectively, power is supplied from the power lines 11a, 11b to the lighting fixtures 7, 7'. The lighting fixtures 7 and 7' are turned on.

[The problem that the idea attempts to solve]

In museums, art galleries, etc. that are equipped with the above-mentioned wiring duct equipment and use power from the wiring duct equipment to provide lighting, it is necessary to dim the lighting equipment when performing lighting effects or redecorating the exhibition hall. . Since the dimming operation in such cases is not performed frequently, it is desirable to provide the dimming knob in a place that cannot be easily touched from the viewpoint of preventing tampering.

However, since the conventional wiring duct device itself does not have a dimming function, it is necessary to use a built-in dimmer for each lighting fixture 7, 7' to dim the lighting fixtures 7, 7'. Alternatively, it was necessary to install a light control facility in the control room or the like and remotely control the light of the lighting fixtures 7 and 7' in the exhibition hall.

In the former configuration using dimming type lighting equipment, each lighting equipment 7, 7' had to be individually dimmed, making the dimming operation extremely troublesome. Furthermore, lighting fixtures with a built-in dimmer are expensive, and there is a problem in that the cost required to perform dimming increases.

In the latter configuration, where the light control equipment is installed in the control room, the installation location of the light control equipment and the installation location of the lighting fixtures 7 and 7' are far apart, and the lighting conditions of the illuminated objects in the exhibition hall can be seen from the installation location of the light control equipment. It was difficult to confirm the lighting conditions, and it was not possible to perform detailed lighting effects. Additionally, there was a problem in that the lighting control equipment in the management room and the wiring duct equipment in the exhibition hall had to be wired, making the wiring work difficult.

The purpose of this invention is to easily perform detailed lighting effects by dimming multiple lighting fixtures powered by the wiring duct body, and to simplify the wiring for dimming while also making it possible to An object of the present invention is to provide a wiring duct device that can reduce costs.

[Means to solve the problem]

The wiring duct device of this invention is composed of a wiring duct body, a power supply connector, and a dimmer. The power supply connector is attached to the end of the wiring duct body to close the opening at the end of the wiring duct body, and brings the plug blade connected to the power line into contact with the conductor in the wiring duct body. In addition, the dimmer is integrally fixed to the connector, and is inserted between the power line and the plug blade in an electrical circuit to control the dimming of multiple lighting equipment that is supplied with power from the conductor in the wiring duct body. I do.

[Effect]

According to the configuration of this invention, by operating the dimmer, it is possible to simultaneously dim the light of multiple lighting fixtures that are supplied with power from the conductor within the wiring duct body, and as a result, dimming of the multiple lighting fixtures can be controlled simultaneously. Easy to operate. Moreover, since the dimmer is integrated with the connector and located near the lighting equipment,
It is possible to perform detailed lighting effects while checking the lighting condition of the lighting target.

In addition, since the dimmer is integrally fixed to the power supply connector, the dimmer can also be fixed at the same time by simply attaching the connector to the wiring duct body attached to the ceiling, etc. No special installation work is required for the dimmer. In addition, since the dimmer is integrally fixed to the connector, the wiring for the dimmer only needs to be done between the connector and the connector, and the wiring can be completed at the time of manufacturing, so it can be done on-site. Wiring work for the dimmer is also unnecessary. Furthermore, since the dimmer cannot be easily touched by hand, tampering can be prevented.

In addition, by integrally fixing the dimmer to the connector, it is possible to control the light of multiple lighting fixtures with one dimmer. The cost required for dimming can be kept low compared to using the same.
