Hereinafter, the configuration and operation of the embodiments of the present invention will be described with reference to the accompanying drawings.

1 is a block diagram of a control system according to the present invention, Figure 2 is a power supply system diagram of the control system shown in FIG.

As the lighting control system has been designed and built in stages and broadcasting studios, the biggest problem in digitization is to illuminate the digital control signal without being affected by the noise caused by the strong surge and noise generated by the power control of tens to hundreds of KVA. Is it delivered securely to the microprocessor in the instrument?

In order to solve this problem, the present invention converts a digital control signal into an optical signal which is not affected by electrical noise using a DMX optical converter, and transmits the digital control signal to a microprocessor in the luminaire through a signal control line.

As shown in FIG. 1, a PC 10, a PC DMX interface 20, a matrix 30, a DMX-optical converter 40, an optical splitter 50, an optical coupling DMX cable reel 60, a fly duct 70a, ..., 70n, the floor pocket 80, and the wall pocket 90 are comprised.

The PC 10 is equipped with a lighting program that can control the irradiation direction, brightness, focus, etc. of the lighting fixtures 74aa, ..., 74nn, and the fly ducts 70a, ..., 70n, the floor pocket 80, the wall. The direction of light, brightness of light, focus of light, and the like of all the lighting fixtures installed in the pocket 90 are controlled.

When the lighting program is driven by the PC 10, the PC 10 is converted into a DMX (Digital Multiplex) signal through the PC DMX interface 20 and transmitted to the matrix 30 through the DMX512 line 1.

The DMX digitally transmits several signals on one line, and the DMX512 protocol is designed to control a lighting console dimmer, and transmits data in the form of a data stream, up to 512 per line. Transmit information on two channels.

The matrix 30 fits the circuit according to the data format which treats two or more data sources as an electronic circuit which transmits on one line without collision.

Since the DMX signal input to the DMX-optical converter 40 through the matrix 30 is an electrical signal, the DMX-optical converter 40 is used to reliably transmit this electrical signal to the luminaire without being affected by noise. The DMX signal is converted into an optical signal and transmitted to the optical splitter 50 through a signal control line 2 made of an optical cable.

The optical splitter 50 divides an optical signal transmitted through one signal control line 2 into signal control lines 2 of several channels, and provides an optical coupling DMX cable reel 60a through each signal control line 2. , ..., 60n) or another optical splitter 52.

The optical coupling DMX cable reels (60a, ..., 60n) and the power supply line (3) to the fly duct (70a, ..., 70n) in which a plurality of lighting fixtures (74aa, ..., 74nn) is installed in the air on the stage The optical signal (data) is transmitted regardless of surge and noise.

An optical-DMX converter that performs the opposite function to the DMX-optical converter 40 when it is impossible to receive an optical signal directly from the luminaires 74aa,..., 74nn installed in the fly ducts 70a,. 72a, ..., 72n are provided inside.

That is, the optical-DMX converters 72a, ..., 72n receive the optical signal transmitted through the signal control line 2 and convert it back to the original DMX signal.

Although not shown in the fly ducts (70a, ..., 70n), the signal control line installation portion and the power supply line installation portion are respectively formed and partitioned by a shielding film.

Each of the luminaires 74aa, ..., 74nn includes dimmers 78aa, ..., 78nn for adjusting the brightness of light, motors 79aa, ..., 79nn for adjusting the irradiation angle of a lamp or light, and a PC 10. Microprocessors 76aa, ..., 76nn which receive the transmitted control signals (optical signals) and directly control the dimmers 78aa, ..., 78nn or the motors 79aa, ..., 79nn in accordance with the control signals are provided.

Another optical splitter 52 connected to the optical splitter 50 divides the optical signal into a plurality of channel signals and transmits them to the floor pocket 80 or the wall pocket 90 through the respective signal control lines 2. .

The floor pocket 80 is a luminaire installed in the form of a pocket on the floor (floor) of the stage, the wall pocket 90 is used when the luminaire is installed near the wall (wall) of the stage.

The floor pocket 80 or the wall pocket 90 may include an optical-DMX converter such as fly ducts 70a, ..., 70n, and each luminaire is provided with a dimmer, a motor, and a microprocessor.

The power distribution panel 100 supplies power to a motor for driving lights and lamps, and this power supply power to the luminaires 76aa, ..., 76nn through the power supply line 3, but the power distribution panel ( The power supply line 3 connected to 100 and the signal control line 2 for transmitting the optical signal converted by the DMX-optical converter 40 are piped together in the same pipe.

Not shown 110 is a power cable reel.

In this way, all the lighting fixtures are digitized and controlled by the PC 10, so that all functions of each lighting fixture can be controlled, stored, and produced, so that lighting output of impossible parts is possible, and the lighting setup can satisfy any condition. (Set Up) is possible.

Therefore, by controlling the irradiation angle, size, color, etc. according to the scene and cue of the lighting at will, one can play multiple roles, and the stage lighting can be satisfied even with a small number of lighting fixtures. All the disadvantages of the limited stationary lighting fixtures can be solved.

In addition, large dimmer system rooms are not required, making space easy and economical.

In addition, the optical cable and the power supply line (3), which are signal control lines (2), are used to convert digital control signals into optical signals that are not affected by electrical noise at all using the DMX-optical converter (40). Since the power cables are piped together in the same pipe, the electric work is simple and the extension work is almost unnecessary.

In the conventional lighting system, when several luminaires 76aa, ..., 76nn installed in the fly ducts 70a, ..., 70n are plugged into the same circuit, operation is simultaneously controlled. Although a plurality of wirings are inevitable, the present invention does not require a plurality of wirings corresponding to each circuit in the fly ducts 70a, ..., 70n, as well as the respective lamps and all functions even if they share the power supply line 3. Because it can control the control is also very convenient and easy to produce the stage.
