7 Drawings Needed Before a Spherical LED Project Starts

A spherical LED display project should not start with production. It should start with drawings.

Unlike a standard flat LED screen, a sphere has a three-dimensional structure. The LED modules must follow the curved surface, the internal frame must support the complete screen, and power and signal cables need to be arranged inside a limited space.

Installation also changes from project to project. Some LED spheres are suspended from a ceiling, while others are installed on a base or fixed structure.

Because of these differences, one simple CAD file is usually not enough. Before production begins, the LED manufacturer, customer, structural engineer, AV integrator and installation team should confirm several important drawings.

Here are seven drawings that can help a spherical LED display project move smoothly from design to installation.

1. General Arrangement Drawing

The General Arrangement drawing, often called a GA drawing, gives an overall view of the project.

It normally shows:

• Sphere diameter
• Overall dimensions
• Installation height
• Distance from the floor
• Position inside the building or venue
• Nearby walls, ceilings or structures
• Basic mounting method

For example, if a 3-meter spherical LED display will be suspended inside a shopping mall atrium, the drawing should show where the sphere sits in relation to the ceiling and surrounding space.

This drawing helps answer a simple question:

Will the LED sphere actually fit the site?

A small measurement mistake can create major problems later. For this reason, the final dimensions and installation position should be confirmed before the sphere enters production.

2. Spherical LED Structural Drawing

The structural drawing explains how the LED sphere is built and supported.

A spherical screen cannot use the same simple rectangular frame as a normal LED wall. The frame must follow the spherical geometry while keeping the complete structure stable.

Depending on the project, the drawing may show:

• Internal steel or aluminum frame
• Frame sections
• Connection points
• Upper and lower hemisphere structure
• Supporting brackets
• Structural dimensions
• Hanging or base connection points

For large spherical LED displays, structural safety becomes especially important because the total screen weight increases with the diameter.

The structural drawing should therefore be reviewed carefully before manufacturing begins.

3. LED Module Layout Drawing

The next drawing shows how LED modules are arranged across the spherical surface.

This is one of the biggest differences between a spherical LED display and a traditional flat LED screen.

A flat screen uses modules arranged in straight rows and columns. On a sphere, modules must follow a continuously changing curve. Special flexible or customized modules are often used to create a smooth surface.

The module layout drawing may include:

• Module size
• Module position
• Module number
• Installation direction
• Module quantity
• Upper and lower sphere sections
• Connection between different sections

Numbering is especially useful. During installation or future maintenance, technicians can quickly identify a module by checking the drawing instead of searching around the complete sphere.

The layout also helps the manufacturer check whether the selected pixel pitch and module design are suitable for the required sphere diameter.

4. Hanging or Mounting Drawing

How will the spherical LED display be installed?

This question should be answered before the screen arrives at the project site.

Common methods include:

• Ceiling suspension
• Floor-standing installation
• Base mounting
• Fixed structural mounting

For a suspended LED sphere, the mounting drawing should clearly show the lifting points, connecting hardware, support structure and installation height. The building structure must also be able to support the total load.

For a floor-standing sphere, the drawing should show the base dimensions, connection points and how the structure is fixed to the floor.

This information allows the installation team to prepare the site before delivery.

5. Power Distribution Drawing

Mechanical drawings alone are not enough. A spherical LED display also needs a clear power plan.

The power distribution drawing shows how electricity reaches the screen and how it is distributed inside the sphere.

It may include:

• Main power input
• Distribution box
• Power supply units
• Cable routes
• Circuit arrangement
• Power connection between modules
• Grounding

The required electrical capacity should be calculated according to the screen size, pixel pitch, brightness and power consumption.

Cable entry is another important detail. For a suspended sphere, visible cables hanging beside the screen can reduce the visual effect. The power cable should therefore be planned together with the supporting structure whenever possible.

6. Signal Connection Drawing

The signal drawing shows how video data travels from the control equipment to the LED modules.

A typical signal path may look like this:

Media Source → Video Processor → LED Controller → Receiving Cards → LED Modules

For a large LED sphere, multiple receiving cards and signal lines may be required.

The drawing should identify:

• Controller position
• Main signal input
• Network cable routes
• Receiving card positions
• Module connection order
• Backup signal lines if required

This drawing is particularly useful during debugging. If one section of the sphere does not display correctly, technicians can follow the signal diagram to locate the possible problem much faster.

Power and signal cables should also be organized separately where necessary to keep the internal wiring clean and easy to maintain.

7. Installation and Maintenance Drawing

A spherical LED screen must not only be easy to install. It should also be possible to maintain after installation.

This is sometimes forgotten during early project planning.

The maintenance drawing can show:

• Assembly sequence
• Module removal direction
• Maintenance openings
• Internal access points
• Power supply locations
• Receiving card locations
• Service space around the structure

Imagine a module fails after the sphere has been operating for two years. Can a technician reach it? Can the module be removed without taking apart a large section of the sphere?

These questions should be answered during the design stage rather than after installation.

Which Drawings Should Be Approved Before Production?

Different teams may need to review different drawings.

For custom projects, drawings may go through several revisions before final approval. This is normal.

Changing a drawing before production is usually much easier and less expensive than modifying a finished LED sphere on site.

What Information Should the Customer Provide?

The manufacturer also needs accurate information from the customer before preparing the drawings.

Useful information includes:

• Required sphere diameter
• Indoor or outdoor installation
• Pixel pitch
• Installation height
• Hanging or floor-standing installation
• Site photos and videos
• Ceiling or supporting structure information
• Available power supply
• Control room position
• Maintenance requirements

If architectural CAD drawings are available, they should also be shared with the LED supplier. For complex projects, site measurements can reduce the risk of errors.

Frequently Asked Questions

What is the most important drawing for a spherical LED display?

There is no single drawing that replaces all the others. The GA drawing confirms the overall size and position, while the structural, module, power and signal drawings explain how the display will be built and operated. All of them should be coordinated before production.

Can a spherical LED display be produced without a structural drawing?

It is not recommended. A structural drawing is necessary to confirm the frame design, support points, total load and installation method. Without it, the display may not be safe or suitable for the building.

Do all spherical LED displays use flexible LED modules?

Not always. The module type depends on the sphere diameter, pixel pitch, viewing distance and required surface smoothness. Some projects use flexible modules, while others use customized rigid modules or segmented structures.

How early should drawings be approved?

Drawings should be reviewed and approved before materials are ordered and production begins. For complex projects, it is better to allow time for site verification, engineering review and several design revisions.

From Drawing Approval to Production

Once all important drawings are approved, the project can move into production.

The typical process is:

Site Information → Concept Design → Engineering Drawings → Customer Approval → Production → Factory Testing → Shipping → Installation

Skipping the engineering stage may save a little time at the beginning, but it can create expensive problems later.

For spherical LED projects, accurate drawings connect the original design idea with the finished installation.

Conclusion

A successful spherical LED display project depends on much more than choosing the right diameter and pixel pitch.

Before production begins, the project should have clear drawings for the overall layout, sphere structure, LED modules, mounting system, power distribution, signal connections and future maintenance.

The more details that are confirmed during the drawing stage, the fewer surprises the installation team will face on site.

For a custom LED sphere, good engineering starts on paper long before the first LED module is installed.
