Phosphor-Coated Side-Emitting Fiber
Phosphor-coated side-emitting fiber, also called remote-phosphor side-light fiber, is a special illumination fiber with a uniform phosphor film on side-emitting plastic optical fiber(POF). Blue light entering one end converts uniformly into white or colored light along the length, creating a soft, continuous linear source without dark areas. Often using silica/polymer substrates, it has phosphor and transparent protective coatings. Blue/UV LED light propagates inside; part excites phosphor to emit longer-wavelength white/green/yellow/red light, while scattering structures provide uniform side emission. I. Three-layer structure:1. Core: Highly transparent PMMA(acrylic) or PS guides blue light by total internal reflection, with high index and transmission.2. Phosphor coating: YAG/nitride/silicate micrometer particles absorb blue and emit yellow/green/red. Dip, spray or vapor coating yields5-20μm thickness.3. Transparent protection: PET, fluororesin or PU provides waterproofing, scratch/oxidation protection, transparency, weather resistance and insulation. II. Remote-phosphor principle:1. Blue LED light enters and propagates by total internal reflection.2. Scattering points/microstructures let some light escape and excite phosphor.3. Phosphor emits yellow/green/red.4. Fluorescence meeting total-reflection conditions continues inside; other light exits laterally through 360°.5. Residual blue and fluorescence mix into the target color, such as blue+yellow=white.
