Case Study: Street Light Thermal Solution
Philips Lumec reduced thermal resistance by 32% using our calculator to optimize fin density for their 150W roadway fixtures.
Technical Deep Dive: Calculating Thermal Resistance
The fundamental equation for heat sink performance:
θja = (Tj - Ta) / Pd
Where θja is junction-to-ambient thermal resistance in °C/W
Industry Trends: Regional Requirements
European EN 62471 standards demand 15% lower junction temperatures than comparable UL standards in North America.
FAQ
Q: Can I use the same heat sink for COB and SMD LEDs?
A: COB modules typically require 20-30% larger surface area due to higher thermal density.
