Description

Angle changer for stage lighting}

The present invention relates to a variable angle device for stage lighting, and more particularly, to obtain various visual lighting directing effects according to the stage environment by adjusting the angle in the direction of vertical elevation and rotation of a square turn bar in which a plurality of lighting devices are installed. And, the entire device is simple, so it was invented to give economic benefits by significantly reducing stage production costs.

In general, in an indoor or outdoor performance, play or event, lighting is used to illuminate a dark place on the stage where the event is held or to maximize the effect of the event.

A plurality of these lighting fixtures are installed around the stage, and the direction, brightness, and focus of each light must be set in advance according to the local stage situation before the event, and the direction of numerous spotlights is fixed to the support with a yoke to set the stage. A stage effect is produced by directing the light of the light in the desired direction by the director or host.

In the case of using lights to illuminate the stage, the direction of irradiation is fixed by screwing many lights for lighting as a yoke to the necessary parts of supports installed in various directions such as longitudinal, transverse, or diagonal directions. And, in the left and right direction, after setting the direction using the rotation of the yoke, the lighting device is prepared by fixing it with a screw so that the direction is not changed.

However, since the direction of the spot light cannot be adjusted during the event, the lighting direction must be adjusted in advance by anticipating all necessary situations in the event.

In order to solve these disadvantages, a direction control device for a lighting device is known in Korean Utility Model Registration No. 20-0271741.

That is, it consists of a rotating part composed of a fixing means that can be fixed to the upper part of the support or stage, a body into which a control unit and a lighting device that emits light are inserted, a top and bottom adjustment unit provided on one side of the body, and a fixing unit on the other side. , The left and right adjustment part enables left and right rotation by the left and right stepper motors.

In addition, the left and right stepper motors allow the rotating part to which the lighting device is coupled to rotate left and right by the belt rotation pipe connected to the pulley.

In addition, the vertical adjustment consists of a configuration in which the drive is transmitted to the vertical rotation shaft through a belt that transmits the drive of the pulley connected to the upper and lower step motors.

However, according to this prior art, the rotation unit for left and right rotation of the lighting device and the vertical adjustment unit for up and down rotation of the lighting device are composed of many parts such as a motor, a pulley, a belt, a rotating pipe, a coupling unit, and the like, and the configuration is very complicated.

Therefore, there is a problem in that the angle of the stage lighting device cannot be smoothly adjusted with a simple and inexpensive configuration, as well as accompanied by an increase in production cost.

On the other hand, in Republic of Korea Registration Utility Model Publication No. 20-0298347, a light is installed on a baton suspended by a wire mounted on the upper part of the support frame, and the light is supplied with power by a multi-core balanced cable, and the multi-core balanced cable is on the baton. We propose a stage set that is stored in a cable storage frame installed in

In detail, a multi-core balanced cable bent to have a ring-shaped bent portion is inserted between a pair of upper and lower aluminum cable bands and fastened with a bolt so that the bending process can be performed easily, and the cable band and multi-core balanced cable are bent. A stage lighting device is proposed in which a rounding part is placed on the contact part so that the cable sheath is not damaged due to the repetitive ascending and descending movement of the baton.

However, in a state where a plurality of lighting devices are installed at the bottom of the barton manufactured in the form of a straight frame, the barton moves up and down using the driving force of a motor connected by a wire to the top of the barton. In addition to adjusting the irradiation direction, the irradiation direction and angle of the lighting device are very limited because the light irradiation direction is performed depending only on the direction conversion ability of the lighting device.

Therefore, there was also a problem that the visual directing effect and directing technique of the stage were not diverse.

Figure 1 shows the entire configuration of the variable angle device for stage lighting of the present invention in a front view.

The fixing frame 10 is fixed while maintaining a horizontal distance from the ceiling concrete layer of the stage facility, and serves as a framework for adjusting the vertical elevation position of the elevating frame 30 through the elevating means 20 described later. .

The fixing frame 10 is firmly installed through the anchors 11 fixed by drilling holes in the ceiling concrete layer and the connecting member 12, so that the lifting motor 21 of the lifting means 20 can be seated thereon. let it be

The elevating means 20 is a device for moving the elevating frame 30 and the lighting fixture 50 attached to the square turn bar 40 up and down together by driving the elevating motor 21 seated on the fixed frame 10. .

2 shows a specific embodiment of the lifting means 20 in an enlarged view.

That is, by firmly connecting the end of the wire 23 wound around the bobbin 22 by the rotation of the lifting motor 21 seated on the fixed frame 10 to the upper end of the lifting frame 30 through an eyebolt or the like, the bobbin As the wire 23 is wound or unwound according to the direction of rotation of (22), the lifting frame 30 is moved up and down.

A square turn bar 40 having a square cross-section is rotatably installed on the lower surface of the elevating frame 30 whose up and down position is controlled through the elevating means 20 through a bracket 41.

Bearings are attached to the bracket 41 to support shafts integrally extending from both ends of the square turn bar 40 so that the square turn bar 40 can be rotated.

At the lower end of the square turn bar 40, a plurality of lighting devices 50 are attached through bolts, etc. while maintaining appropriate intervals, and rotated together with the square turn bar 40 to change the irradiation angle of the lighting devices 50. be able to

In order to adjust the angle of the lighting fixture 50 attached to the bottom surface of the square turn bar 40, a forward and reverse motor 60 is installed through a support plate 61 attached to the lifting frame 30, and a power transmission means 70 ), the rotation of the forward/reverse motor 60 is transmitted to the square turn bar 40.

Therefore, it is possible to rotate and adjust the rectangular turn bar 40 and the lighting fixtures 50 attached to the bottom portion thereof at a predetermined angle.

As the power transmission means 70, sprockets 71 and 72 are installed on the motor shaft of the normal and reverse motor 60 and one end of the square turn bar 40, respectively, and then connected through a chain 73 to the normal and reverse motor The angle of the lighting fixture 50 can be adjusted along with the square turn bar 40 according to the rotation direction of the 60.
