Description

DETAILED DESCRIPTION OF THE INVENTION [Field of the Invention] The present invention relates to a lighting system, and more particularly, when a lighting equipment is connected to any outlet circuit, the lighting equipment is turned on according to the fixture number of the lighting equipment. 1! The present invention relates to a lighting system that allows lighting control by specifying lighting operations such as lights.

[Background of the Invention] Conventionally, lighting systems for stages, studios, etc. are known that have a plurality of outlet circuits that can be dimmed for each circuit and plugs that can be freely connected to these outlet circuits. In such a lighting system,
By connecting each lighting fixture to an outlet in an outlet circuit installed at the required location and controlling the dimmer circuit installed in each outlet circuit, it was possible to meet diverse demands for stage lighting systems. .

However, in such conventional lighting systems, lighting control such as turning on or dimming each lighting fixture must be performed by controlling the dimmer circuit of the outlet circuit to which the lighting fixture is connected. The operator has to judge which outlet each lighting fixture is connected to, which makes the lighting control operation extremely complicated and makes it impossible to control the lighting quickly and accurately. Furthermore, each time the outlet circuit to which a lighting fixture is connected is changed, the lighting control for each outlet circuit must also be changed, or the lighting fixture must be replaced in order to obtain the desired lighting control state. There were also some inconveniences.

In order to eliminate such inconveniences, a method is conventionally known in which each lighting device incorporates a dimming circuit using a thyristor or the like and a control signal receiver for dimming. However, such a method has the disadvantage that the configuration of each lighting fixture becomes extremely complicated and costs increase, and that such a lighting fixture cannot be used as a lighting fixture in the conventional lighting system described above.

[Summary and Object of the Invention] In view of these problems in the conventional type, the present invention provides a lighting system for use on stages, studios, etc.
Based on the concept of providing each lighting fixture with a switch that sets a fixture number and a fixture number transmitter that transmits the fixture number information specified by this switch, we have created a simple configuration that allows lighting control to correspond to the fixture number. The purpose is to enable quick and accurate lighting operations on stages, studios, etc.

[Explanation of Examples] Hereinafter, the present invention will be explained in detail with reference to the drawings.

FIG. 1 schematically shows a lighting system according to an embodiment of the invention. In the system shown in the figure, each outlet 1-1.

．． 2-2. . . , may be performed separately every 2-m, or these outlet circuits 2-1

2-m may be divided into a plurality of groups, and the dimming control may be performed for each group. In this case, the dimmer circuit 3 will be provided with a dimmer having a thyristor or the like for each control unit.

FIG. 2 shows each lighting fixture 5-1 in the system of FIG.
．． 5-2. . . , 5-N shows the internal configuration of one of the lighting fixtures 5. The lighting fixture 5 shown in FIG. 2 includes a light source 7, such as a light bulb, connected by a plug 4 and a power cord 6;
It is equipped with an appliance number setting switch 8, an appliance number transmitting device 9, and a coupling capacitor 10, which are comprised of dip switches and the like.

Next, the operation of the lighting system having the above configuration will be explained. Assume that in the lighting fixture shown in FIG. 2, the number of the lighting fixture is set by the switch 8, and such a lighting fixture is connected to a certain outlet circuit 6 in FIG. 1 by the plug 4. In such a case, the fixture number transmitting device 9 in the lighting fixture 5 transmits fixture number information according to the setting state of the switch 8 to the coupling capacitor 10.
and is sent out via the power cord 6. This appliance number information is input from the plug 4 to the dimming circuit 3 via the corresponding outlet circuit. The light control circuit 3 automatically determines the correspondence between the lighting equipment and the outlet circuit from the received appliance number and the number of the outlet circuit that received the appliance number, and stores this in, for example, a storage device (not shown). In this way, the dimming circuit 3 detects and stores the correspondence between the lighting fixture number and the outlet circuit for each lighting fixture connected to the outlet circuit. Then, when the operator specifies the fixture number and inputs an operation signal for lighting control such as blinking the lighting fixture or specifying the dimming level, the dimming circuit 3 selects the fixture number from the fixture number included in this operation signal. The outlet circuit to which the lighting equipment is connected is automatically determined, and the lighting control specified by the operation signal is performed on the dimmer corresponding to the outlet circuit. In this way, in the above-mentioned system, by specifying lighting operations based on the fixture number, the operator can automatically control the corresponding lighting fixtures without having to judge which outlet the lighting fixture is plugged into. Lighting control is performed.

Note that the light control circuit 3 in FIG. 1 can be constituted by a thyristor connected between an AC power source and each outlet circuit, a microprocessor controlling the thyristor, and the like.

Furthermore, in the above system, the appliance number information is transmitted using the lighting power cord 6, that is, the power line, but it is also possible to install a dedicated transmission line and outlet for transmitting the appliance number. be. Furthermore, the correspondence between each lighting fixture and the outlet circuit can be determined by the fixture number information transmitted individually for each outlet circuit as described above.Another method is to install an outlet number setting switch on each outlet side. It is also possible to transmit the correspondence information between the lighting equipment and the outlet circuit to the dimmer circuit 3 by using a transmission device that transmits a combination of information according to the setting state of this outlet number setting switch and the above-mentioned appliance number setting switch. It is possible. In this case, the correspondence information between each lighting device and the outlet circuit can be transmitted using a common transmission line, and it is also possible to share any power line.

[Effects of the Invention] As described above, according to the present invention, lighting operations can be specified in correspondence with each lighting fixture number, so there is no need for the operator to judge the connection correspondence between each lighting fixture and the outlet circuit. The lighting operation procedure becomes extremely simple, and it becomes possible to quickly and accurately set stage lighting, etc.
