ATS thermal consulting team gives leading LED manufacturer a 33% improvement in their heatsinkperformance

A leading LED manufacturer approached ATS regarding a high heat LED thermal management problem. Their original heat sink design for a 6W LED light with a vertical orientation had specifications of Rhs of 9 K/W and a dThs of 54 C at ambient.

ATS analyzed their design, factoring in the position of the light (vertical) and how they might effect the design to bring greater improvements and headroom. ATS’s thermal engineering consulting included:

  • Testing the heat sink physically in our thermal lab
  • Creating models using CFD to determine the optimal design
  • Developing and Manufacturing samples to be re-tested in our lab, prior to moving to general availability for our customer.

The result was a 33% improvement in the heatsinks performance. See the following chart for the before and after technical results (click chart for a clearer and larger image):
