The United States Honeywell new phase change thermal management materials, can prolong the service life of the LED

Recently, HoneywELl announced the development of a new series of phase change thermal management materials (phase-changing thermal management material), the phase change in service enhancements cooling efficiency, and extend the display backlight, solid-state lighting applications such as the LED array of life.

It is understood that the Honeywell LTM6300-SP series phase change material is a polymer based (polymer matrix), can replace the traditional mass production, but it will be aging at high temperature of the silica gel substrate, embedded in the thermal conductivity of metal. The LTM6300-SP polymer is filled with micron sized (micron) sized metal particles, but based on trade secrets, Honeywell did not disclose the exact size. The principle of heat dissipation is that the material will soften when the temperature rises, then the internal metal particles were forced to directly touch the LED heat source, so the heat transfer to the material, and then enhance the heat dissipation.

Honeywell Electronic Materials (HEM) technology long Brian Daniels said that the thermal management materials can enhance the efficacy of LED performance, extend its life, and to ensure that the color will not be dimmed because of overheating. Daniels pointed out that, because LED is a semiconductor, so the high power LED array will require heat management materials due to the generation of heat, and LTM6300-SP series is achieved through the phase change. "This HEM developed for various LED lighting application of the first phase change material, its characteristic is to respond to heat, can be controlled by the solid to the soft liquid phase change, thus improve the thermal performance in the system at elevated temperatures. This could lead to a reduction in LED in advance of brightness, color change and even burn the harmful heat, will be taken away from the LED semiconductor components at the rate of temperature rise.
