Honeywell launches thermal management material to boost LED performance

Honeywell of Morris Township, NJ, USA has developed the LTM6300-SP thermal interface material, which it claims can improve the energy efficiency of LEDs through effective transfer of heat generated by LED lamps.

As LEDs become smaller, faster and more powerful, more heat is being generated in a confined space, which can damage the LEDs’ performance. If LEDs overheat, they become dim, their color is muted and their lifespans are shortened.

As semiconductor devices, LEDs require more precise heat management than traditional light sources, the firm adds. Honeywell says that its thermal management materials are designed to meet this specific challenge, helping to effectively transfer heat in semiconductor applications.

LTM6300-SP is a high-thermal-performance phase-change material that is claimed to be superior to silicone-based products, which typically pump out and degrade at high temperatures. Based on the firm’s packaging expertise in thermal management, LTM6300-SP is designed to be used mainly as a screen-printable paste and complements Honeywell’s other thermal interface products.

“LTM6300-SP is the first in a series of HEM [Honeywell Electronic Materials] phase-change materials being developed for the growing LED segment,” says Brian Daniels, chief technology officer of HEM (part of Honeywell Specialty Materials). LTM6300-SP was designed for LED backlights for flat-panel displays, but the packaging technology can be also implemented in LEDs used in a wide range of applications, from automobiles to computers.
