What If Your Emergency Exit Sign Could Actually Guide You Through Smoke?

The Problem with Traditional Exit Signs in Real Emergencies

In a real fire, thick smoke quickly fills corridors and cabins, reducing visibility to near zero. Traditional exit signs-whether fluorescent or basic LED-often become invisible in these conditions. Their light is too dim, too directional, or too easily obscured by smoke particles.

The Science of Visibility in Smoke

Visibility in smoke depends on the contrast between the illuminated sign and the surrounding environment. The Emergency Exit LGP Board achieves exceptional contrast through its uniform, high-brightness illumination.

A New Standard for Life-Saving Signage

The Emergency Exit LGP Board represents a new standard for emergency exit signage in vehicles, buildings, and public spaces. It is not just about meeting minimum regulatory requirements-it is about maximizing visibility in the worst-case scenario.

How LGP Technology Penetrates Smoke and Fog

Uniform Illumination for Maximum Visibility

This uniform illumination ensures that the entire exit symbol-not just the brightest spots-is visible through smoke. The result is a clear, sharp, and easily recognizable exit sign that guides occupants to safety even when visibility is severely compromised.

High Luminance for Cutting Through Smoke

Luminance-the intensity of light emitted from the surface-is critical for penetrating smoke. The Emergency Exit LGP Board delivers luminance levels optimized for emergency conditions, ensuring that the exit symbol remains bright and visible even in dense smoke.

Wide Viewing Angle for Multi-Directional Evacuation

The Emergency Exit LGP Board maintains its brightness and contrast across a wide viewing angle of up to 160 degrees, ensuring that the exit symbol remains legible no matter the approach direction. This wide-angle performance ensures that all occupants can find their way to safety.

Fire-Resistant Materials for Emergency Conditions

Part 1 – UL 94 V-0 Flame-Retardant Construction
An Emergency Exit LGP Board is manufactured using flame-retardant materials that meet UL 94 V-0 standards-self-extinguishing within 10 seconds without flaming drips. The LGP substrate is made from fire-resistant polycarbonate (PC), which offers inherent flame resistance far superior to PMMA.

Part 2 – Halogen-Free Fire Retardants for Reduced Toxic Smoke
Modern Emergency Exit LGP Boards use halogen-free flame retardants, such as phosphorus-based additives, to achieve V-0 ratings without the toxic smoke emissions associated with halogenated compounds.

Part 3 – Thermal Stability for High-Temperature Conditions
During a fire, temperatures can rise rapidly. The Emergency Exit LGP Board is engineered to maintain its structural integrity and optical performance at high temperatures. PC-based boards offer VICAT B50 softening temperatures around 124°C, significantly higher than PMMA's 98°C.

Customization for Diverse Evacuation Needs

Multilingual Messaging for International Settings

An Emergency Exit LGP Board can be customized to display exit instructions in multiple languages, ensuring that all occupants-regardless of language-can understand the evacuation guidance.

Directional Arrows for Complex Evacuation Routes

An Emergency Exit LGP Board can incorporate directional arrows that are uniformly illuminated, providing clear guidance even in smoky conditions. The arrows can be customized to point toward the nearest exit or to indicate alternate routes.

Floor Number Indicators for High-Rise Buildings

An Emergency Exit LGP Board can include illuminated floor number displays, helping occupants orient themselves and emergency responders coordinate rescue efforts.

Graphical Evacuation Plans for Complex Facilities

An Emergency Exit LGP Board can display simplified floor plans with exit routes clearly marked. The LGP technology ensures that the graphics are uniformly illuminated and easily readable, supporting safe and efficient evacuation.
