3M Thermal Interface Tapes Help to Improve The Life of an LED Lighting Application

Challenge

An LED lighting manufacturer came to us seeking ways to improve the lifetime performance of LED bulbs within their fixtures.

This company was previously using a thermal grease to help transfer the heat being created from the bulbs away from the enclosure.

The problem with using a thermal grease is that it can get quite messy, and unless you are used to working with thermal grease, it is hard to apply and evenly distribute.

Solution

SRP recommended a thermal interface material to dissipate the heat in the fixture. This material is designed to provide a heat transfer path between heat generating components and cooling devices.

We also suggested a microcellular urethane to prevent environmental contaminants from entering the product. We were con dent this was the perfect solution to prolong the life of the LED bulbs.

Results

Our customer was pleased that their thermal-management product was now higher performing and superior to its predecessor. The elimination of the thermal grease resulted in a much simplified assembly process as well.

These cost saving improvements reduced assembly time immensely, while providing more ef cient distribution of heat throughout the application.
