PMMA bare fiber (polymethyl methacrylate bare fiber) is a plastic optical fiber with a high-purity PMMA core. Its excellent flexibility and light transmittance make it an ideal choice for decorative lighting. It is also an end-emitting plastic optical fiber that can be illuminated by LEDs. It offers excellent quality at a low price.
Specifications include:
KINZ PMMA 0.25mm
KINZ PMMA 0.5mm
KINZ PMMA 0.75mm
KINZ PMMA 1.0mm
KINZ PMMA 1.5mm
I. Core Advantages: Why Choose PMMA Bare Fiber?
1. Material Characteristics: Made of PMMA (organic glass), it is highly flexible (can be bent into any shape without breaking), weather-resistant (can operate in temperatures ranging from -20°C to 60°C), lightweight (only 1/5 the weight of glass fiber of the same specification), and easy to install.
2. Controllable Lighting: It does not emit light on its own and requires a light source. Adjustable light sources can create effects such as solid-state, multi-color gradients, and twinkling (Twinkle) to meet diverse decorative needs.
3. Safety and Environmental Protection: Contains no glass and produces no sharp fragments upon breaking, making it suitable for use in homes and children's play areas. It complies with RoHS standards and releases no harmful substances during long-term use.
II. Specification Variations: How to Choose Between 0.25mm and 1.5mm?
PMMA bare fiber diameters vary significantly in light efficiency, density, and applicable scenarios, as follows:
III. Typical Application Scenarios: Lighting Coverage from Subtle to Dramatic
0.25mm/0.5mm: Suitable for dense, "starry" effects, such as starry ceilings in children's rooms (500-1000 fibers can be laid per square meter) and "galaxy"-like backdrops for wedding photography.
0.75mm/1.0mm: A balance of density and brightness, suitable for living room starry ceilings, bar counter outlines, and automotive interior ambient lighting (such as door trims).
1.5mm: A single fiber offers a more striking light effect, suitable for wrapping around banquet hall columns, outdoor landscapes (such as tree decorations), and large-scale light strips for exhibition booths.
IV. Usage Tips
Light Source Compatibility: Fibers with a diameter of 1.0mm or greater are recommended to be paired with a light source of 10W or higher to avoid dimming due to insufficient power. 0.25mm/0.5mm fibers can be paired with a 5W-8W light source for energy-saving and uniform light output.
Installation Notes: Allow some slack when laying (recommended 5% longer than the actual length) to avoid excessive stretching that could affect light transmission. Use dedicated clips when securing the fiber to avoid squeezing the fiber and reducing light transmittance.
