QLED software simulation tool shines a light on developing LED thermal management solutions

While all our team here at Advanced Thermal Solutions are proud of the thermal design work we do here (and we have happy customers to back that up – see bottom of this page for some of them), thermal engineering is a pretty big space for an engineering niche. So we like to point out useful things we find along the way. Some of them we’ve tried and some we haven’t but the QLED LED Thermal Simulation Software Tool looks like one we’ll be putting on our list.

QLED Thermal Simulation Tool was developed by Future Electronics Lighting Solutions and Qfinsoft. Here’s the quick breakdown of what it does:

Developed in conjunction with Qfinsoft, QLED reduces LED application design cycles, development costs and time to market by eliminating the traditional trial-and-error approach to thermal design. The software guides users through step-by-step design wizards to select, place and simulate power LEDs mounted on FR-4 boards or MCPCBs. It also calculates the expected luminous flux produced by the LED and allows users to seamlessly integrate thermal vias, heat sinks and fans to generate the most accurate transient or steady state thermal simulations.

This sounds like a useful tool. We use CFD everyday here in our lab at ATS, (we happen like Blue Ridge Numeric’s CF Design) so we know the value of good, simulation software to reduce the design time of a thermal management solution. Seeing a tool like QLED sounds to us like a great addition to a standard CFD tool pack.

Heat Sink Modeling using Compact Models: A “how to” article from ATS Thermal Labs

The methodology for compact thermal modeling of electrical components is described in the JEDEC standard, JESD15-1.  A detailed model of both component and heat sink can be used for single component level analyses. Board and system level analyses require compact components to represent the thermal behavior of a component and to limit the amount of grid cells and related computer power. Our article discusses the methodology of compact heat sink modeling. We provide some modeling background then compare detailed, substitute and compact modeling.
