Reliability Testing of LED Modules for Indoor/Outdoor Displays

To meet stringent quality requirements from global clients, our LED modules undergo rigorous aging tests to ensure durability and performance in both indoor and outdoor environments.

Aging Test Protocol

International customers specifically mandate a 72-hour accelerated aging process, including:

Thermal Stress: Continuous operation at 60°C (outdoor) or 50°C (indoor)

Humidity Exposure: 85% RH for outdoor-rated IP65 modules

Voltage Cycling: 120% rated voltage stability checks

Thermal Shock: Rapid temperature shifts (-30°C ↔ +60°C)

Performance Validation

All modules are tested for:

Optical Consistency: ≤0.003 ΔE color deviation after aging

Environmental Resistance:

Outdoor: Waterproof/dustproof validation (IP65)

Indoor: Anti-oxidation coating durability

Electrical Safety: 1000-hour surge immunity (IEC 61000-4-5)

Cross-Application Reliability

Modules demonstrate:

50,000+ hour lifespan (L70 standard)

Stable operation in -20°C to +60°C ranges

<0.1% pixel failure rate post-testing

These tests confirm our modules meet international standards for diverse applications, from indoor control rooms to outdoor stadium displays, ensuring 5+ years of maintenance-free service.
