Technical Deep Dive
Modern LED arrays require thermal interface materials (TIMs) with minimum 6W/mK conductivity for 100W+ applications. The chart below shows performance curves for different solutions:
How Thermal Pads Solve Junction Temperature Issues
Phase-change materials (PCMs) bridge microscopic gaps between LEDs and heat sinks, reducing thermal resistance by 40% compared to grease alone. Leading manufacturers like Bergquist and Henkel now offer:
- Gap-filling to 0.5mm
- Automated dispensing options
- Silicon-free formulations
2024 Market Trends
European Union's new Ecodesign Regulation (EU) 2023/814 mandates 15% better thermal efficiency for commercial LED fixtures. Key regional differences:
- North America: Demand for liquid-cooled LED systems (+22% YoY)
- Asia-Pacific: Growth in ceramic substrate adoption
- Middle East: Extreme temperature-grade solutions
FAQ
Q: Can I use standard thermal paste for COB LEDs?
A: Not recommended - chip-on-board modules require electrically insulating materials with ≥8W/mK conductivity.
Q: What certifications matter for export?
A: UL 94V-0 for flammability, IEC 62471 for photobiological safety, and IPC-4101 for material standards.
Q: How to calculate HS code for thermal materials?
A: Typically falls under 3815.90 for prepared heat transfer compounds, but verify with local customs.
