Seamless Splicing Spherical LED Screen Display Lightweight Floor Mounted

Fixed-Installation LED Spherical Screen – Product Description

The fixed-installation LED spherical screen typically features a floor-mounted load-bearing base structure. The entire weight of the sphere is transferred through the internal radial steel framework to the bottom steel base, and ultimately to the building's ground floor – without relying on roofs, main beams, or any upper building structures for support.

All supporting systems are fully integrated within the base, including:

• Power distribution system

• Thermal management system

• Receiving cards

• Maintenance access walkways

This design delivers exceptional structural stability and supports a variety of spherical configurations, including:

• Full sphere (complete 360°)

• Hemisphere

• Sphere with a viewing/cutout opening

The fixed-installation LED spherical screen is the mainstream solution for professional dome theaters, planetariums, science museums, and other specialized exhibition venues.

Top‑Hung LED Spherical Screen – Product Description

The top‑hung LED spherical screen features a fully suspended overhead structure with no floor‑level support. The entire weight of the sphere is transferred through an integrated load‑bearing top mounting plate, steel cables, and embedded suspension anchors, all of which are securely fastened to the building's top main beams.

This design offers an unobstructed, transparent visual presence with no ground‑level blockage, making it ideal for atrium voids, high‑end showroom floating displays, and open‑concept exhibition spaces.

However, this configuration imposes strict limitations on:

• Product lightweight design

• Building load‑bearing capacity

• Ceiling height clearance

As a result, it is not suitable for large‑scale or heavy‑weight spherical screens.

III. Applicable Size Ranges (Industry‑Wide Hard Upper Limits)

The most critical differentiator in selecting between the two solutions is that floor‑mounted installations have no size restrictions, whereas suspended installations have a clear size ceiling.

1. Floor‑Mounted Applicable Sizes (Full‑Spec, Universal Across All Sizes)

• Small spheres: Φ1m – Φ4m
  (Corporate showrooms, laboratories, small‑scale exhibitions)

• Medium spheres: Φ4m – Φ8m
  (Science and technology museums, the mainstream size for commercial spaces)

• Large spheres: ≥ Φ8m
  (Planetariums, large‑scale cultural tourism immersive venues, outdoor landmarks)

Advantage:
Relying entirely on ground load‑bearing capacity (provided the floor foundation is adequately reinforced), this solution can realize ultra‑large‑diameter spherical screens with no structural upper limit.

III. Applicable Size Ranges (Industry‑Wide Hard Upper Limits)

The most critical differentiator in selecting between the two solutions is that floor‑mounted installations have no size restrictions, whereas suspended installations have a clear size ceiling.

1. Floor‑Mounted Applicable Sizes (Full‑Spec, Universal Across All Sizes)

• Small spheres: Φ1m – Φ4m
  (Corporate showrooms, laboratories, small‑scale exhibitions)

• Medium spheres: Φ4m – Φ8m
  (Science and technology museums, the mainstream size for commercial spaces)

• Large spheres: ≥ Φ8m
  (Planetariums, large‑scale cultural tourism immersive venues, outdoor landmarks)

Advantage:
Relying entirely on ground load‑bearing capacity (provided the floor foundation is adequately reinforced), this solution can realize ultra‑large‑diameter spherical screens with no structural upper limit.

2. Ceiling‑Mounted / Suspended Applicable Sizes (Strictly Limited)

• Recommended standard sizes: Φ1m – Φ5m
  (Commercial atriums, lobbies, exhibition halls – the most common range)

• Custom‑made limit sizes: Φ5m – Φ7m
  (Requires dedicated structural reinforcement of the building, and is very rarely implemented)

• Prohibited selection red line: Diameter > 7 m is strictly forbidden for suspension.

Reason:
For spheres larger than 6 metres, the self‑weight becomes extremely high. The cost of reinforcing the building’s main beams far exceeds that of a floor‑mounted installation, and the high‑altitude safety risks become uncontrollable.

IV. Applicable Weight Ranges (Data from Online Sources; For Reference Only)

1. Floor‑Mounted Weight Ranges

• Φ1–3 m: Total unit weight 0.1–1.5 tons, with an additional 0.8–1.5 tons for the base counterweight.

• Φ4–8 m: Total unit weight 2.5–12 tons, with a heavy‑duty reinforced‑concrete base weighing 2–5 tons.

• Φ9–15 m: Total unit weight 13–30 tons, with a large concrete base weighing 5–10 tons.

Floor load‑bearing requirement:
The concentrated floor load must be ≥ 12 kN/m², with a safety margin factor of 1.5×, which is generally achievable in standard exhibition halls and venues.

2. Ceiling‑Mounted / Suspended Weight Ranges

• Φ1–4 m lightweight spheres: Total unit weight 0.1–3.6 tons
  (the most stable range for commercial applications)

• Φ4–6 m extreme suspended spheres: Total unit weight 3.8–6.5 tons
  (custom lightweight versions required)

Industry safety red line:
The recommended maximum total suspended weight is ≤ 7 tons.

Load‑bearing standard for suspension:
The lifting points must meet a safety factor of 5 times the self‑weight (for example, a 4.2‑ton sphere requires lifting points with a capacity of ≥ 21 tons). The suspension system must be anchored to the building's main structural beams; direct loading on standard floor slabs is strictly prohibited.

I. General Information

II. Dimensions & Weights

1. Floor‑Mounted (Ground‑Fixed)

Notes: A safety margin of 1.5× is applied by design. Standard exhibition hall floors generally meet the requirement. Floor‑mounted installations have no structural upper limit; super‑large sizes up to 30 m can be custom‑built.

2. Ceiling‑Mounted / Suspended

Industry safety red lines:

• Recommended maximum total suspended weight: ≤ 7 t

• Lifting points must meet a safety factor of 5× the self‑weight (e.g., a 4.2 t sphere requires a lifting‑point capacity of ≥ 21 t).

• The suspension system must be anchored to the building’s main structural beams; direct loading on standard floor slabs is strictly prohibited.

• Diameter > 7 m is strictly forbidden for suspension.

3. Typical Product Weight References

Area‑weight reference: Display self‑weight is generally ≤ 30–35 kg/m²; some lightweight designs can be as low as 16 kg/m².

III. Installation Methods

The same sphere can support both floor and suspended modes, but the load‑bearing design must be finalised before manufacturing; the two modes cannot be interchanged after production.

Spherical LED Display – 10 FAQs

1. Q: Can a spherical screen be suspended? What is the maximum diameter?
   A: Yes, but the diameter is strictly limited to ≤ 7 m. The recommended standard range for suspended spheres is Φ1–5 m. Any diameter above 7 m must be floor‑mounted.

2. Q: What is the difference between floor‑mounted and ceiling‑mounted installation? Can they be interchanged?
   A: The load‑bearing mechanics are completely different (compression vs. tension), and the structural design, centre‑of‑gravity layout, and maintenance access also differ. They cannot be mixed or interchanged after factory production.

3. Q: What ceiling height is required for installation?
   A: For floor‑mounted: sphere diameter + 1.2 m. For suspended: sphere diameter + 2.3 m (including 0.8 m for rigging and 1.5 m bottom safety clearance). A ceiling height below 6.5 m cannot accommodate a medium‑sized suspended sphere.

4. Q: What is the maximum sphere size available?
   A: Floor‑mounted has no structural upper limit and can be custom‑built up to 30 m or more. Suspended has a hard limit of 7 m.

5. Q: Is there a weight limit for suspended spheres?
   A: The industry recommendation is a total suspended weight ≤ 7 t. Lifting points must meet a safety factor of 5× the self‑weight (e.g., a 4.2 t sphere requires a lifting‑point capacity of ≥ 21 t), and the system must be anchored to the building’s main structural beams.

6. Q: Is maintenance convenient? Are costs high?
   A: Floor‑mounted units have bottom access doors for ground‑level service – maintenance is simple. Suspended units require aerial work or lowering the entire sphere for repairs, with post‑maintenance costs roughly 30% higher than floor‑mounted.

7. Q: Can the sphere be made with openings, cut‑outs, or hemisphere shapes?
   A: Floor‑mounted supports any shape (full sphere, truncated, opening, hemisphere, etc.). Suspended units are mostly full spheres; cut‑outs are rarely used to avoid centre‑of‑gravity imbalance.

8. Q: Can the screen be used both indoors and outdoors? What about protection ratings?
   A: Indoor models are rated IP43; outdoor models are IP65 (dustproof and waterproof), with a wider operating temperature range (-20°C to +60°C).

9. Q: How do I choose the pixel pitch?
   A: It depends on the optimal viewing distance (1–50 m). Common pitches range from P1.25 to P10. Smaller pitch provides higher clarity but increases cost and weight.

10. Q: What are the typical applications for spherical LED displays?
    A: Science centres, museums, corporate showrooms, commercial atriums, planetariums, cultural‑tourism immersive venues, outdoor landmarks, etc. Suspended units are better for commercial traffic‑generating installations and temporary exhibitions; floor‑mounted units are suitable for year‑round permanent operation and large professional screens.
