Why Precision Thermal Management Matters?

 Critical Heat Challenge

LEDs convert70% of energy into heat—without proper cooling, junction temperatures exceeding 150°C cause30% lumen decaywithin 3 years and shorten lifespan from 50,000h to <10,000h.

 

Lumen Depreciation

Thermal resistance as low as1.2℃/Wstabilizes junction temperature.

Without proper cooling:
• 30% light output loss in 3 years
• Junction temp >150°C
 

Design Compromise

Aluminum-copper composite materials balance weight and heat dissipation efficiency.

Optimized balance:
• 40% weight reduction vs. copper
• 85% thermal efficiency retained
 

Corrosion Risks

Anodized surfaces pass 1,000+ hour salt spray tests for coastal projects.

Protection features:
• Marine-grade anodizing
• 1000h+ salt spray resistance
 
Industry Insight:
Heat dissipation design flaws account for27%of total LED after-sales costs.
