SU365745A1 - DEVICE FOR CONTROL OF LIGHTING - Google Patents

Description

The invention relates to the field of lighting engineering and is intended for equipping lighting devices of theaters and other entertainment enterprises.

The systems of remote control of lighting devices are known, for example, a system of the DPU-1 type, mass-produced by domestic industry and installed in the studios of the All-Union Telecentre in Ostankino. However, this system has the disadvantage that makes it impossible in practice to use it in theaters, circuses and other entertainment enterprises and to limit its use even in film studios.

Such a disadvantage is the inability to change the color of the light beam of lighting devices by a given program, which drastically reduces production possibilities.

The aim of the invention is to extend the functionality of the device for controlling lighting devices, which allows, in addition to changing the space of the light beam, to control its color according to a given program.

This goal is achieved by installing on lighting devices blocks of light filters with remote control and a step finder, which switches the energy-proof drive of the color filters using intermediate relays through the contacts of the bodies.

The block diagram of the proposed device is depicted in FIG. one; The control unit diagram (control from the main zero) - in FIG. 2; The circuit of the control unit (control from the operating panel) - on FIG. 3

In the drawings, the applications are designated as follows: / - the main control panel, including the unit 2 of programmed light filter control; 3 - control unit, including the unit - / control and the drive filters; 5 and 6 switching units, ОД1Н1 of which (5) includes an additional switching unit 7, which provides both a software to compensate for the optical flux tramp from the zero, and a selective control unit from the operational zero; 8-block actuators for lighting installed on lighting systems 9.

The block 2 of the light-frequency filter control unit contains a step finder W, an intermediate relay 11, opraiH i beam color software, two-way switches 12 and light-signal positioning lamps 13. Block 7 contains ground switching relays 14. The light filters contain frames with replaceable light filters (not shown in the drawing).

equipped with reversible electromagnetic actuators 15. Dip switches 16 are used to set the beam color of a selected block of light filters, and the block is selected by switch 17, one of the fields of which is directly related to controlling the light filters is shown in FIG. 3

The operation of the system in controlling the light filters from the main control panel is carried out as follows (see Fig. 2).

For the program set, the chromaticity of the lighting devices of the switches 12 are set in accordance with the color score of the light rays. At the same time, a signal lamp 13 is ignited against each switch 12, fixing a predetermined position of the light filters ("Entered," Removed). In this way, the switching circuit 18 of the electromagnetic actuators 15 of the light filters in accordance with a predetermined program is prepared.

When the button 19 is pressed, the movement of the brushes 20 of the quench finder W starts automatically. With each finder of the finder, the coils of the corresponding intermediate relays 14 and 11 are sequentially connected to the power supply. These pairs of relays, with their normally open contacts, connect the coils of electromagnets 15 to the power source through program switches 12, putting them into positions specified by the program.

After walking around all the lighting fixtures, the X-ray finder automatically stops in its original position. The part of the circuit that implements the automatic stop in the initial state is not shown in the drawing.

If it is necessary to control the light filters, double penetrating switches 16 are used. Using the switch 17, the desired block of light filters is selected (switching on one of the intermediate relays 14).
