Summary of the invention The object of the invention is to provide a large number of stage lights of the kind used in musical or theatrical performances. The objective is to simplify the assembly, transportation, installation, and disassembly of light appliances.

Another object of the present invention is to provide light over an arc of approximately 360 degrees without interfering with the beam. The beam is directed onto a stage light, but the stage light is protected by a case during transportation. The objective is to obtain a truss unit that can be housed within the space.

Each of the above purposes is modular in the sense that it can be connected to an electrical signal bus. Achieved by a modular m:-shaped truss unit.

The two-shape truss unit has a working structure that displays complex stage lighting, and a stage lighting and a protective storage and transportation structure. The stage lighting system is a truss frame or at least two hung in rows. A transverse member is attached to each side of the hinge connection point. truss The frame, the facing transverse members, and the bulging solid are combined to provide stage illumination during transportation. Protect light equipment.

In the operative configuration, opposing transverse members extend upwardly from the hinge point. centre When the frame is used as a walkway, the transverse member can be used as a handrail. high If you want a more expensive lighting system, several truss units can be removably put together. It is possible to connect to

The horizontal members are separate legs. The truss unit is installed in a securely packed structure that protects the truss unit during transportation. maintain. The rings on each leg are used to extend the truss unit onto the stage and pull it in from the stage. make it easy to move.

One problem found in the design of such folding assemblies is that certain trusses Pan or tilt illuminators in adjacent illuminator rows in the unit from the gimbal mechanism. They must be separated by a sufficient distance to enable this.

One solution to this problem is to significantly increase the width of the truss unit. death However, the present invention mounts each illuminator on a horizontal bar for movement in a sliding motion.

During transport, the illuminator is moved to a central position and then moved outward before operation. rare illuminator A T-clamp is used to hold it in the desired position.
