Why Precision Thermal Management Matters?
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.
Design Compromise
Aluminum-copper composite materials balance weight and heat dissipation efficiency.
Corrosion Risks
Anodized surfaces pass 1,000+ hour salt spray tests for coastal projects.

Frequently Asked Questions
What are the minimum order quantities for custom LED heat sinks?
Our minimum order quantity typically starts at100 piecesfor custom designs. However, we can accommodate smaller quantities for prototyping and testing purposes. Contact our sales team for specific requirements and pricing.
How do you ensure consistent thermal performance across production batches?
We employ rigorous quality control processes including3D coordinate measuring machines (CMM)from Zeiss and Hexagon, thermal testing protocols, and statistical process control to ensure consistent performance across all production batches.
Can you provide thermal simulation and design optimization services?
Yes, our engineering team provides comprehensivethermal simulation using advanced CFD software, design optimization recommendations, and prototype testing to ensure optimal thermal performance for your specific LED applications.
What surface treatments are recommended for outdoor LED applications?
For outdoor applications, we recommendType III anodizingwith enhanced corrosion resistance. This treatment passes 1000+ hour salt spray tests and provides excellent thermal emissivity while protecting against environmental factors.
What is your typical lead time for custom heat sink projects?
Lead times vary based on complexity and quantity. Typically,prototype samples take 7-10 days, tooling development requires 2-3 weeks, and production runs are completed within 3-4 weeks after approval. Rush orders can be accommodated with expedited processing.
