A 3D LED hologram fan is designed to simulate three-dimensional images by utilizing a rapidly spinning set of LED blades, typically mounted on a rotating motor. The LED blades operate at extremely high speeds, often ranging from 600 to 1,000 RPM (revolutions per minute). The lights emitted from these blades create a visual effect that appears to float in the air, much like a hologram. The technology relies on persistence of vision, a phenomenon where a human eye perceives an image as continuous when it is viewed in rapid succession, thus allowing the brain to interpret the spinning LED lights as a three-dimensional object.

These hologram fans are typically built with a high degree of resolution, offering crisp, clear images that are perfect for various applications. Depending on the model and the rental service provider, 3D LED hologram fans may come in various sizes, ranging from smaller models ideal for personal use and small gatherings, to larger units designed for bigger events and commercial use.
