Fiber optic decorative curtains are made of optical fiber as the main material. They emit light through the internal light source device, which can present a colorful visual effect. They can use fiber optic engraving technology to present specific patterns such as stars, and realize dynamic changes such as jump and gradient changes in light colors through programming. They are often used in commercial places such as shopping malls, bars, KTVs, etc. to create an atmosphere, and can also be used for home decoration to add a romantic and dreamy feeling.
