The 42cm Two-Blade 3D Holographic LED Fan Projector (Wi-Fi / Bluetooth Audio / UK 3-Pin Plug) is an innovative visual display and creative advertising system engineered to produce ultra-realistic floating 3D holographic graphics and video effects. Utilizing high-density POV (Persistence of Vision) technology, dual high-speed rotating blades equipped with 224 ultra-bright RGB LEDs spin rapidly to render transparent-background 3D imagery that appears to float seamlessly in mid-air. Featuring seamless Wi-Fi connectivity for wireless smartphone (iOS / Android) and PC content management, integrated Bluetooth audio output for synchronized sound, and a fused UK 3-pin power adapter, this 42cm display is widely deployed in retail showrooms, exhibition booths, shopping malls, restaurant storefronts, holiday displays, and digital signage installations.

Usage Tips

• Content Creation & Background Rule (CRITICAL): The illusion of "floating in air" relies on contrast. Always create or render videos and animations with a pure pitch-black (#000000) background. When rendered on the spinning fan, black pixels turn completely off, making the background invisible while the 3D subject floats in mid-air.
• Mounting Safety Clearance (Mandatory):
  • Install the unit at a minimum height of 2.8 meters (9 feet) above the floor, or enclose it inside a transparent protective acrylic dome / showcase box.
  • Never touch the rotating blades while the device is running; the high RPM can cause physical injury and break the LED strips.
• Blade Assembly & Balancing: When attaching the two blades to the motor hub, ensure all retaining screws are tightened evenly with the provided mini screwdriver. Uneven torque can cause rotational vibration and motor noise.
• Wi-Fi & App Pairing: Connect your mobile phone directly to the fan’s Wi-Fi hotspot (default SSID typically starts with `3D-XXXXX`, default password usually `12345678`) before opening the control app to manage playlists.
• Bluetooth Audio Pairing: In the mobile app or PC software settings, turn on "Bluetooth Search" to automatically pair with your nearby Bluetooth speaker for synchronized sound playback.
• Shut Down Procedure: Always use the remote controller or mobile app to power off the motor and let the blades come to a complete stop before unplugging the 12V DC power cable.
