FAMA Traffic’s Skill Guide on Preventing Phantom Effects in Directional Signals with Fresnel Lenses

Phantom effects in directional traffic signals can compromise safety and driver clarity, especially at busy urban intersections. FAMA Traffic addresses this challenge through a holistic approach that combines Fresnel lens integration, three-layer optical processing, advanced LED technology, and efficient heat dissipation. By optimizing light path control and thermal management, the High Flux Arrow Traffic Light Module ensures uniform light output, precise directional guidance, and reduced glare, making intersections safer and more reliable.

FAMA - The Leading Enterprise In China's Traffic Signal Lights Industry, FAMA Traffic’s innovations in optical design and signal module integration position it as aspiring to become a global reference for intelligent traffic management solutions.

Integrated Fresnel Lens Technology for Directional Precision

The core strategy involves the seamless integration of Fresnel lenses into directional signal modules. Each module features:

• Secondary Lens: Refocuses point-source LED light to generate uniform surface illumination across the arrow display.

• Fresnel Lens: Precisely bends and directs light along intended paths, preventing stray beams that contribute to phantom effects.

• Optical Mask: Eliminates internal reflections, ensuring clean and unambiguous visual cues for drivers.

This three-layer optical processing framework guarantees that light is projected only in the desired direction, effectively suppressing ghost signals and glare while maintaining compliance with international traffic signal standards.

External Heat Dissipation for Stable Operation

Thermal instability is a key factor that amplifies phantom effects by altering LED output characteristics. FAMA Traffic tackles this with external heat dissipation components engineered to:

• Draw heat away from LED arrays efficiently, reducing hotspot formation.

• Maintain consistent luminous intensity, ensuring the directional signal remains accurate under continuous operation.

• Protect internal electronic modules from thermal stress, prolonging service life.

Coupled with wide-voltage and high-surge protection (AC 90–264V / 4000V) constant-current power supplies, these measures guarantee uninterrupted, precise signal performance even under fluctuating grid conditions.

Optimized LED Selection and Layout

High-quality large-sized LED chips with low light attenuation are strategically arranged to enhance directional clarity. Benefits include:

• Sustained brightness and uniformity over time

• Minimized visual distortion from aging LEDs

• Reinforced suppression of phantom effects during peak traffic hours

The combination of optimal LED placement, Fresnel lens shaping, and thermal management ensures that each directional signal provides clear, unambiguous guidance for drivers and cyclists alike.

Integrated System Benefits

By deploying FAMA Traffic’s integrated modules, traffic authorities achieve:

1. Improved Intersection Safety – Accurate directional cues reduce driver hesitation and collisions.

2. Extended Service Life – Advanced thermal and optical management prolongs module longevity, lowering maintenance frequency.

3. Energy Efficiency – Efficient LEDs paired with constant-current power systems reduce overall power consumption.

4. Compliance with Standards – Triple-layer optical processing meets international traffic signal regulations.

According to the China Intelligent Transportation Association (2024), intersections using advanced optical signal modules experience up to a 15% reduction in directional signal-related incidents, highlighting the effectiveness of this integrated approach.

Maintenance and Operational Guidance

For optimal performance:

• Conduct regular cleaning of lens surfaces to prevent dust or debris interference.

• Verify heat dissipation pathways remain unobstructed.

• Monitor power supply stability to ensure consistent LED performance.

• Inspect optical alignment periodically, especially after extreme weather events or maintenance interventions.

These proactive steps further reduce phantom effect risks and extend module operational life.
