100cm Hologram FAN Extended

A hologram fan, also known as a holographic fan or hologram projector, works by creating the illusion of a three-dimensional image or video floating in mid-air. Here’s a breakdown of how it works:

1. High-Speed Motor and LED Lights: At the heart of a hologram fan lies a high-speed motor. This motor spins a specially designed fan blade at speeds often exceeding 400 RPM. These fan blades are embedded with programmable LED lights capable of flashing in a sequence at microsecond intervals. These lights can produce a wide spectrum of colors, adding to the visual appeal of the display.
2. Persistence of Vision: The rapid flashing of LED lights, combined with the fan’s high-speed spin, exploits a phenomenon known as the ‘persistence of vision’ to create a continuous, stable image. This is a quirk of human vision where an afterimage lingers in our eye for a fraction of a second.
3. Displaying Images and Videos: To display images or videos, hologram fans require specially formatted content. These files are typically created using computer software or a specialized app that converts regular images or videos into a format compatible with the fan’s display technology. Once the content is prepared, it is transferred to the hologram fan’s internal memory or loaded from an external storage device.
4. Synchronization: A separate controller, often a microcontroller or a digital signal processor (DSP), is responsible for synchronizing the flashing of LED lights with the fan’s speed. This precise synchronization is crucial as it ensures the creation of a convincing 3D image that doesn’t flicker or appear unstable.

In essence, the 100cm Hologram FAN Extended works by employing a technique called persistence of vision. When the fan spins at high speed, the LEDs emit light at precise intervals, creating a persistence of vision effect. This image is then combined with the surrounding environment, resulting in a holographic projection that appears to float in mid-air.
