- Thermal interface material thickness
- Dielectric strength requirements
Technical Deep Dive: Heat Transfer Mechanisms
As shown in our thermal resistance diagram, effective LED heat conduction requires:
The junction-to-case thermal resistance (θJC) should be <1.5°C/W for commercial applications. Leading manufacturers like Cree and Lumileds now require:
- UL94 V-0 flame rating
- 500V dielectric withstand
- 10-year performance warranties
Regional Market Insights
European buyers prioritize:
- Halogen-free materials (IEC 61249-2-21)
- Full RoHS 3 compliance
While North American markets focus on:
- UL certification
- ASTM E595 outgassing standards
