POF vs Glasfiberbelysning: Smarte løsninger og økotrends

1. Plastic Optical Fiber (POF): The Powerhouse of Popular Innovation

Plastic optical fiber, thanks to its flexibility, ease of installation, and low cost, has become the most widely used material in decorative lighting. Its diameter typically ranges from 0.5 to 3mm, and its weight is only one-third that of glass fiber of the same length, allowing for flexible routing around complex curves and confined spaces.

POF’s core advantage lies in its exceptional impact resistance—it remains fully functional even after being stepped on or bent. It can also be cut without specialized tools, significantly lowering the barrier to DIY renovations. This makes it a popular choice for starry sky ceilings and creative wall decorations, particularly in homes.

Technically, POF utilizes the principle of total internal reflection transmission, coating the fiber core (typically PMMA polymethyl methacrylate) with a low-refractive-index coating to ensure efficient transmission of visible light. While transmission distance is typically limited to 30 meters, it perfectly meets the decorative needs of small and medium-sized spaces.

Bio-based POF materials developed by companies such as Asahi Kasei in Japan, incorporating biodegradable properties, are driving the category’s evolution towards environmental friendliness.

2. Side-lighting Fiber: The Creator of Linear Aesthetics

Side-lighting fiber (also known as volume-emitting fiber) utilizes a unique structural design to evenly distribute light from the sides, creating a continuous, soft, linear light effect. Its surface brightness can reach 300-1500 lux, three times the brightness of traditional neon lights, while reducing energy consumption by over 40%.

The key technological breakthrough lies in its microstructured optical design: scattering particles or micro-prismatic structures are incorporated into the fiber core to precisely control the light’s escape angle. With a diameter of 8-15mm, it can be bent into any desired arc, replacing traditional rigid light strips.

• Concealed stair lighting: Embedded in the side of the treads, it creates a suspended light strip to guide the path.
• Translucent concrete curtain wall: Composited with building materials, invisible during the day and luminous at night.
• Light guide for art installations: Wrapping around the contours of sculptures, light redefines the spatial dimension.

Nanjing Zhanrui Optoelectronics’ case study demonstrates that side-lit optical fiber with a PVC UV-resistant sheath has been used in an outdoor fountain setting for five years without any signs of aging or yellowing, demonstrating its environmental adaptability.

3. RGB Color-Changing Fiber: The Catalyst for a Scene Revolution

When ordinary optical fiber is combined with an intelligent lighting system, dynamically color-changing RGB fiber is born. Its core is a three-in-one composite fiber core structure, which transmits red, green, and blue primary color beams through independent channels, mixing them at the terminal to create 16.7 million colors.

Corning’s ColorFX system has achieved millisecond-level color switching. Combined with the DMX512 control protocol, the entire fiber can display different colors in sections. This technological breakthrough has transformed spatial mood adjustment from concept to reality—simulating the white glow of dawn at breakfast, switching to a romantic warm orange at dinner, and instantly transitioning to neon mode for parties.

Shanghai Disneyland’s “Magic Light Corridor” project uses 8 kilometers of RGB optical fiber to create an immersive nighttime walkway, consuming only 7.5W per square meter, less than one-third the power of traditional landscape lighting.

4. Glass Fiber Optic (GOF): The Invisible Pillar of High-End Scenery

Although glass fiber optics only account for approximately 15% of the decorative market, they are irreplaceable in certain areas. Their ultra-low transmission loss (<3dB/km) allows for illumination distances of hundreds of meters, eliminating the need for additional light sources for large-scale building facade lighting projects.

Germany’s Rheinland Cable’s high-temperature-resistant series, capable of withstanding ambient temperatures of 300°C, was selected by the Louvre’s Department of Oriental Art for illumination of artifact display cases. Glass fiber optics filter 99.3% of infrared and ultraviolet rays, preventing artworks from aging due to light exposure.

In the crystal chandeliers of the Burj Al Arab in Dubai, thousands of GOF optical fibers conceal the light source within the ceiling. The heat-free nature of the lamp allows cleaning staff to directly handle the light source for maintenance, highlighting its unique value in ultra-high-end projects.

5. Safety and Energy Saving: The Ultimate Answer to Dual Urgent Needs

The revolutionary breakthrough of fiber-optic lighting lies in the physical separation of light and electricity. The light source can be placed in a safe area such as a distribution box, allowing only the non-powered optical fiber to enter a pool, around flammable materials, or within reach of children. This feature enables it to obtain IP68 waterproof certification and certification for use in explosion-proof locations.

Energy Efficiency Comparison (Same Luminous Flux Output)

The energy-saving performance is equally impressive: By distributing a 200W metal halide light source to 50 light points via optical fiber, the equivalent power consumption is only 4W per point. After adopting this solution, the museum’s lighting electricity costs dropped by 40%, and its air conditioning load was also reduced.

6. Selection Decision Tree: Optimal Solution for the Scenario

• Creative Home Renovation: POF plastic optical fiber** is the preferred choice, with costs ranging from ¥15-30 per meter. Paired with a 75W halogen light source, it can create a 20-square-meter starry sky ceiling. Nanjing Zhanrui’s case study shows that DIY installation takes an average of only 3 hours.
• Commercial Space Upgrade: RGB color-changing systems are a traffic engine for window displays and bars. It’s recommended to pair them with a Wi-Fi controller for mobile color adjustment. Sumitomo Electric’s Stage series supports music rhythm functions.
• Outdoor Landmark Project: Weather-resistant GOF glass optical fiber**, coated with a fluororesin sheath for UV protection, must be used. China Telecom Fiber’s Polaris series has been deployed in the Hong Kong-Zhuhai-Macao Bridge landscape belt.
• Cultural Relics and Medical Facilities: Choose full-spectrum glass optical fiber**, ensuring a CRI > 98 and preventing UV damage. Corning’s PureWhite series is used by the British Museum.

7. Intelligence and Sustainability: The Dual Evolution of the Future

IoT technology is reshaping fiber optic lighting. Voice-activated systems are becoming the new standard—through pressure-sensing elements embedded in the fiber coating, the ground light path can detect footsteps and illuminate node by node.

At the forefront of materials technology, bio-based POF and recyclable glass preforms are hot research topics. Asahi Kasei’s Ecopet series, launched in 2024, uses 30% plant-based materials in its fiber core, reducing its carbon footprint by 57%.

The surge in 5G deployment is giving rise to a new category of photonic crystal fiber (PCF). Its unique air-microporous structure achieves 95% light energy utilization and is soon to be used in full-body interactive light fields in virtual reality venues.

Fiber Optic Material Properties and Application Scenario Matrix

Glass fiber optics, like a rigorous scholar, safeguards the high-fidelity transmission of light in museum display cases and hotel chandeliers. Plastic fiber optics, like a nimble dancer, brings the starry sky and its phantoms into the homes of ordinary people. Side-lighting fiber optics, with their elegant lines, reshape spatial contours, while RGB color-changing fiber optics, with their dynamic spectrum, rewrite the emotional script of commercial spaces.

With bio-based materials reducing their environmental footprint and photonic crystal structures improving light-guiding efficiency, fiber optic lighting has transcended the stage of mere functional satisfaction. Whether we gaze at artificial galaxies in children’s rooms, chase color-changing light strips in shopping malls, or gaze at losslessly illuminated artifacts in ancient monuments—these scenes all point to the quietly spreading revolution of light along the delicate fibers.
