Lighting truss is light-weight metal, often aluminum or steel, used to support lighting or clamp on lighting in the lighting industry. It is commonly used in overhead lighting, to support lighting fixtures and to hang lighting. It may also refer to open-ended lighting truss and/or stage lighting truss. It is a structural component of the lighting system and has loads of uses for its weighty size and design.
Lighting truss is usually formed by four lateral members (called as beam members in engineering literature) and one vertical member, called the box member. The box members can have two to several double beams. Each of them can have a pitch to allow free transfer of energy when lighting fixtures are set in them. They also play an important role in supporting the weight of lighting fixtures and provide a firm and sturdy framework for the rest of the system, such as the stage truss, so that the entire fixture does not break. This article discusses the uses and structure of stage, overhead lighting truss and the box truss in lighting systems.
In general terms, there are four different types of lighting truss - L-shaped, U-shaped, D-shaped, and angle-load. The four are named because of the arrangement and shape of their lateral or upright members. The L-shaped is the simplest of the four. It has three flat surfaces on which the beam of light can be suspended.
U-shaped lighting trusses are usually preferred in building structures or where space is limited. They are usually required in the corners where there are two or more light fixtures. These are the common issues in U-shape lighting trusses.
D-shaped is the most popular design of lighting truss used in the construction industry. Its common sizes include L, U, and D. Its characteristic features are long spans and strong connections. Its diagonal members are connected along three common sizes: L-shaped, D-shape, and angle-shaped. Its diagonal members are most commonly connected together at a distance of 30 feet or more.
Lighting truss systems generally come in standard, L-shaped, U-shaped, and D-shape. All these have common sizes and are commonly used in residential buildings and large industrial structures. However, different construction methods and materials may create differences in the shape and size of the beam. When this happens, it's necessary to follow the guidelines and requirements stated in the Builders' Manual. One of the most common sizes of a D-shape is used in residential buildings. It can be found in most residential buildings because of its flexibility to install inside stairwells and around landscaping.
If you own a lighting contractor and you want to use a lighting truss in your business, you have to make sure that it meets the building's requirements. The next thing that you have to check out is the truss' load table. The load table is the dimension that's used in determining the maximum weight of the beam. The best stage is the first one to undergo compression. Make sure that the stage doesn't experience any damage before installing the lighting truss in your stage.
When you're looking for a lighting truss, aluminum truss is usually used. Aluminum is widely used because it's strong, rigid, durable, lightweight, and available in a wide range of colors and designs. It also maintains its strength and color with the years making it a great choice for stage lighting fixtures. Compared to wood, aluminum lights are more cost effective because they don't depreciate that much from time to time. Since aluminum trusses are light in weight and easy to install, many people use them to create attractive lighting display at their event.
