The 45cm Four-Blade 3D Holographic LED Fan Projector (Wi-Fi / Bluetooth Audio / UK 3-Pin Plug) is a high-resolution, professional visual display system engineered to render high-density, borderless 3D holographic animations and floating video advertisements. Utilizing advanced Persistence of Vision (POV) technology, its 4-blade high-speed rotor assembly is equipped with 510+ ultra-dense RGB SMD LEDs, delivering significantly smoother frame rates, higher pixel density, and richer color depth than two-blade models. Featuring dual wireless connectivity with mobile app/PC Wi-Fi control and integrated Bluetooth audio synchronization, alongside a BS 1363 compliant UK 3-pin power supply, this 45cm 3D fan is widely deployed in commercial retail, exhibition centers, high-end showroom windows, corporate lobbies, and stage events.

• Synchronized Bluetooth Audio: Built-in Bluetooth transmitter pairs with external Bluetooth speakers or soundbars, combining floating 3D visuals with high-fidelity background audio.
• Video Wall Splicing Capability: Advanced firmware allows multiple 45cm fans to be networked and synchronized together to form large-scale holographic video walls.
• Safe, Fused UK 3-Pin Supply: Premium BS 1363 certified power adapter includes built-in surge, overcurrent, and thermal cutoff protection for 24/7 retail operation.

Common Applications

• High-End Retail & Fashion Boutiques: Floating 3D displays for footwear, jewelry, cosmetics, luxury watches, and branded fashion accessories.
• Trade Show & Expo Displays: Eye-catching 3D brand animations, exploding-view mechanical models, and dynamic product showcases.
• Hospitality, Bars & Nightclubs: Floating digital cocktail menus, VIP promotions, festive graphics, and entertainment signage.
• Corporate Showrooms & Tech Lobbies: Interactive 3D logos, mission statements, and holographic welcoming kiosks.
• Museums & Science Centers: Displaying 3D floating anatomical models, planetary systems, and historical artifacts in mid-air.

Usage Tips

• Pitch-Black Background Rule (CRITICAL): To achieve the true floating hologram effect, render all custom videos and 3D animations with a 100% solid black (#000000) background. The display automatically turns off pixels in black zones, rendering the background completely invisible.
• Safe Installation Height: Mount the fan at least 2.8 meters (9+ feet) above ground level, or enclose it inside an optional transparent acrylic safety dome/case to prevent accidental contact with spinning blades.
• Blade Installation Order: Align each of the four blades with its corresponding labeled slot (e.g., A, B, C, D) on the center motor hub, and fasten all locking screws securely using the included screwdriver before powering on.
• Pairing Wi-Fi & Bluetooth:
  • For Content Upload: Connect your phone/laptop to the fan's broadcasted Wi-Fi SSID (usually `3D-XXXXX`, password `12345678`) and open the management software.
  • For Audio: Open the app audio settings, enable Bluetooth scan, and select your external Bluetooth speaker to pair audio output.
• Shutdown Procedure: Always turn off the device via the remote control or app and wait for the blades to come to a complete stop before disconnecting the mains power.
