LED – Cooling and Thermal Management
LED – Cooling and Thermal Management As we all know, the life span of an LED depends on the semi-conductor material used as well as the current/heat relationship. The light output of the LED becomes weaker and weaker and once it reaches 50% of its initial value, the life expectancy of the LED has, by definition, been reached. A life span of a few hundred and up to 100,000 hours is possible, but only when avoiding high temperatures which drastically reduce the length of the LED’s life. Read more »

Thermally Activated Degradation of Phosphor-Converted White LEDs
Thermally Activated Degradation of Phosphor-Converted White LEDs The increasing performances and long lifetime of High Brightness LEDs are still limited by the high temperatures involved. This work shows the results of several accelerated lifetime tests on 1W white LEDs. Two different tests have been carried out: a pure thermal storage at different temperatures and an electrical aging obtained by biasing the LEDs. The impact of high temperatures has been evaluated in terms of flux decay, chromatic properties modification, increase of forward voltage and thermal resistance. A picture of the main degradation mechanisms detected has been provided in detail. Read more »

Diamond Brightens the Performance of Electronic Devices and LEDs
Diamond Brightens the Performance of Electronic Devices and LEDs Two new studies performed at the U.S. Department of Energy’s Argonne National Laboratory have revealed a new pathway for materials scientists to use previously unexplored properties of nanocrystalline-diamond thin films. While the properties of diamond thin films are relatively well-understood, the new discovery could dramatically improve the performance of certain types of integrated circuits by reducing their "thermal budget."

Litecool Turns LED Packaging on Its Side
Litecool Turns LED Packaging on Its Side Litecool has produced LED packages in a vertical orientation rather than horizontal. This means that the dielectric layers only have a minor impact on the thermal performance of the LED package and allow the heat to escape more effectively through the metallic parts of the package. This has significant benefits for flip-chip packaging where dielectric layers are usually very close to the diode. Read more »

Intended for High-Performance Computer Chips - Maybe Also Useful for LEDs
Intended for High-Performance Computer Chips - Maybe Also Useful for LEDs The inner workings of high-power electronic devices must remain cool to operate reliably. High internal temperatures can make programs run slower, freeze or shut down. Researchers at the University of Illinois at Urbana-Champaign and The University of Texas, Dallas have collaborated to optimize the crystal-growing process of boron arsenide – a material that has excellent thermal properties and can effectively dissipate the heat generated in electronic devices.

MIT Researchers Developed New Heat Conducting Polymer Films
MIT Researchers Developed New Heat Conducting Polymer Films Polymers are usually the go-to material for thermal insulation. Think of a silicone oven mitt, or a Styrofoam coffee cup, both manufactured from polymer materials that are excellent at trapping heat. Now MIT engineers have flipped the picture of the standard polymer insulator, by fabricating thin polymer films that conduct heat — an ability normally associated with metals. In experiments, they found the films, which are thinner than plastic wrap, conduct heat better than many metals, including steel and ceramic. Read more »
