The HOLILITE large piano-shaped LED light display has a standard height of 4 meters and uses a hot-dip galvanized steel frame, outdoor LED light strings, and flame-retardant tinsel. The full piano profile includes the main body, raised lid, keyboard area, and lower support structure. It is designed for light festivals, theme parks, commercial plazas, scenic areas, public parks, Christmas markets, and large seasonal lighting projects.
The product uses a modular steel structure. Each structural section is formed, welded, fitted with lighting, and checked at the factory before being separated for transport. Overall size, piano proportions, lighting colors, surface colors, logo elements, and themed details can be customized for the project.

Product width, depth, weight, total power, LED quantity, operating voltage, packing dimensions, and shipping volume are confirmed from the final approved design.
The 4M scale requires a clear and recognizable piano profile. Lid curvature, body length, keyboard position, and lower proportions are designed as one complete structure to maintain the correct visual balance at large scale.
The main steel frame forms the outer curve of the piano. Continuous bent steel sections connect the front, side, and rear areas while controlling the overall length and body thickness.
The upper lid creates one of the strongest visual features of the piano. Lid outline, opening angle, and upper height are coordinated with the main body proportions.
The keyboard is positioned at the front of the piano with a separate structural and lighting zone, keeping the keys visually distinct from the main body.
The lower steel structure connects the piano body to the installation surface and provides support and fixing points for the large frame.
LED light strings are arranged around the piano outline and structural zones. The lighting layout covers the raised lid, main body, keyboard, and lower edges so the complete piano form remains clear at night.
LED strings follow the external body line to define the full piano shape.
Upper lighting highlights the curved raised lid and reinforces the height and direction of the structure.
The main surface uses distributed LED coverage across the large tinsel area.
The keyboard uses a separate lighting layout to distinguish the front key section from the main illuminated body.
Lighting color, LED quantity, power, and circuit layout are determined from the final size and lighting design.
The main frame uses hot-dip galvanized steel. Steel tubes are cut, bent, and welded to form the body, lid, keyboard area, and lower support while carrying the LED strings and surface materials.
LED strings are fixed to the steel frame and surface areas to define the piano outline and provide body illumination. Circuits are arranged by structural zone for installation and maintenance access.
Tinsel covers the visible piano surfaces and creates a textured decorative finish. It maintains a complete daytime appearance and reflects the LED lighting at night.
The 4M piano is divided into structural sections according to product dimensions and transport space. Module interfaces, installation direction, and electrical connections are positioned during factory production.
| Main Body Modules | Large body sections divided to suit transport dimensions |
| Upper Modules | Raised lid and upper curved sections connected separately |
| Lower Modules | Support structure for body loading and site fixing |
| Structural Interfaces | Positioned and checked during factory assembly |
| Module Numbering | Marked according to on-site installation sequence |
| Electrical Connections | LED circuits divided according to structural sections |
Site planning for a large piano display covers structure orientation, installation area, visitor circulation, power access, and fixing method.
The keyboard and raised lid define the main viewing side. The front-facing direction should be aligned with the main visitor route during layout planning.
The site should allow enough space for the piano footprint, installation work, viewing distance, and visitor access.
Commercial plazas, paved park areas, and permanent display sites can use a steel base with suitable anchor hardware according to the structural plan.
The power connection position should be confirmed during project planning to avoid unnecessary cable changes after installation.
Basic service clearance should be kept around the structure for inspection of LED strings, connection points, and ground fixings.
The base and fixing plan are determined from product dimensions, exposed surface area, foundation conditions, and local wind conditions.
| Overall Size | Height, length, width, and body proportions |
| Piano Body | Main curve and external proportions |
| Raised Lid | Outline, size, and opening angle |
| Keyboard Area | Width, proportions, and lighting layout |
| Surface Color | Configured to the project theme |
| LED Color | Configured to the lighting design |
| Logo | Brand logo, lettering, and event elements |
| Theme Design | Music, Christmas, festival, and commercial themes |
| Structural Modules | Divided according to transport and installation conditions |

The piano form has a strong music-related identity and can work as a standalone illuminated sculpture or as a central element within a larger themed area.
The piano can be combined with musical notes, guitars, violins, saxophones, performer figures, and stage-inspired lighting elements.
The 4M piano can serve as a large visual point along a light festival route or as part of a connected themed display.
Suitable for shopping mall entrances, pedestrian districts, and open plazas, with optional logo and brand integration.
Suitable for music zones, winter event areas, night-tour routes, and large outdoor seasonal scenes.
Suitable for night tours, music events, seasonal light exhibitions, and large outdoor themed projects.
Suitable for city squares, public parks, and cultural event areas together with other large illuminated installations.
After structural fabrication, the piano enters assembly and lighting inspection. Large modules are checked for dimensions, interfaces, electrical circuits, and surface finishing before packing.
| Steel Frame Dimensions | Check body, lid, keyboard, and lower structure |
| Structural Interfaces | Check module connections and installation direction |
| LED System | Check light strings, connectors, and zone circuits |
| Full Lighting Test | Check complete operating condition before packing |
| Surface Finish | Check tinsel coverage and fixing condition |
| Installation Parts | Verify structural connectors and electrical accessories |
The 4M piano is packed by structural module. Large curved frames, connection interfaces, LED circuits, and tinsel surfaces receive separate protection.
Cushioning materials are placed between modules to reduce metal impact and surface abrasion during long-distance transport.
The raised lid, body edges, and other projecting areas receive separate protection against compression.
Tinsel-covered areas are kept away from direct contact with steel parts and hard packing materials.
Packing is configured according to product dimensions, order quantity, and shipping method.
After packing, package quantity, dimensions, gross weight, and total volume can be confirmed for freight booking, customs clearance, unloading, and site handling.
After drawing approval, the steel structure, module layout, LED arrangement, installation structure, packing, and shipping plan are finalized.
The standard height is 4 meters. Length, width, and body proportions are determined by the final design, and custom dimensions are available.
