DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a movable lighting device used for a theater stage or a stage of various halls, for example.

[0002]

2. Description of the Related Art Lighting devices used in concert halls, theaters, and the like independently control the illumination direction and color or the brightness of each of the lighting devices constituting the illumination device in order to obtain various effects. This type of lighting device is a movable lighting device that includes a plurality of movable lighting fixtures and a control device that controls them.

FIGS. 3 and 4 show a conventional movable lighting device. The movable lighting device includes a movable lighting fixture 1 and a control device 2 thereof.

[0004] In the movable lighting fixture 1, a fixture main body 1a provided with a light source therein is hung by a baton 3, and a motor installed in the fixture main body 1 drives the fixture main body 1 around a shaft attaching portion 3a of the baton. By rotating the baton shaft 3b by rotation or by driving a motor installed at the end of the baton 3, the vertical irradiation angle (tilt) of the light source in the instrument body 1
t)) and the horizontal illumination angle (pan) can be arbitrarily set.

In addition, three color filters of red, blue and green are provided in front of an irradiation optical path of a lamp as a light source.
Each color filter is rotated by each motor, and a red, blue, or green filter is selectively interposed in front of the light source, so that the color of light emitted from the movable lighting fixture 1 is adjusted.

The control device 2 transmits control signals to respective motors for adjusting the vertical and horizontal illumination angles of the light source, the rotation angle of the color filters, etc., and controls the vertical and horizontal illumination angles of the light source. And a control panel 2a as setting input means for an operator to manually input information on the rotation angle of the color filter and the like, and a movable lighting fixture 1 corresponding to the input
Address setting device 2b for assigning a code to assign an address of
And a transmitter (data link) 2c for transmitting the set address signal and the information (parallel data) as serial data.

On the side of the movable luminaire 1, a receiver 1b connected to the transmitter 2c by a signal line 4 for converting serial data sent from the transmitter 2c into parallel data is located at the head of the serial data. An address selector 1c for identifying whether or not the data is data relating to a specific movable lighting fixture 1 from a signal; and a driver for driving a vertical illumination angle, a horizontal illumination angle, a rotation angle of a color filter, and the like by each parallel data. And a driving device 1d composed of a motor.

[0008] That is, when the operator specifies a specific movable lighting fixture 1
Is operated, the switch or lever of the control panel 2a, which is the setting input means of the control device 2, specifies the movable lighting fixture 1 to be operated and operates the movable lighting fixture 1 to a desired color or position. Enter the information to make it work. The transmitter 2c transmits each information as serial data to the receiver 1b of the movable lighting fixture 1 via the signal line 4 with the address signal given by the address setting unit 2b at the head. In the receiver 1b, the serial data is converted into parallel data, and it can be determined whether or not the movable luminaire 1 is a desired movable illuminator 1 by the address selector 1c. Transfer and drive each motor. In addition,
The address of each movable lighting fixture 1 is mechanically set by switching a switch provided in the address selector 1c of the movable lighting fixture 1.

The control device 2 in such a movable lighting device has a different number of control axes depending on the type of the movable lighting device 1. Therefore, each time the type of the movable lighting device 1 is different, the control device 2 is suitable for it. A dedicated control device 2 corresponding to the number of control axes is used.

Although not shown, a dimming control console, which is another control device for setting the illumination level of each movable lighting fixture, is connected to such a movable lighting fixture separately from the above-described control device. The illumination level can also be made variable.

[0011]

However, in the conventional movable lighting device thus configured, the control device 2 of the movable lighting device 1 includes the control device 2 for setting the irradiation direction of the movable lighting device 1; Since it is separated into a dimming control console which is a control device for setting an illumination level, a plurality of operators are required to control the control device 2 for setting the irradiation direction and the dimming control console during the preparation work, respectively. In addition to the two types of control devices, not only can the preparation work not be performed, but also a large installation space is required. Since the numbers are different, a dedicated control device 2 corresponding to the number of control axes is used, and a single type of control device 2 cannot control different types of movable lighting fixtures 1 in a mixed manner. There is a problem to say.

Furthermore, when different types of movable luminaires 1 are used in combination, the number of control axes is different, so that there is a problem that address setting (computation becomes complicated) in the transmitter (data link) 2c. there were.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems. It is an object of the present invention to enable a single control device to operate the setting of the irradiation direction and the illumination level, and to use different types of movable units. It is an object of the present invention to provide a movable lighting device that can easily control even when lighting devices are mixed.
