Lighting performance of LEDs used in displays and other applications

Morristown, New Jersey, USA, September 14, 2009-Honeywell (NYSE: HON) today announced that it has developed a new thermal management material that can improve light-emitting diodes (LED) At present, light-emitting diodes (LEDs) are increasingly used in street lamps, car lights, flat-screen TV monitors and computer monitors.

The new product is called Honeywell LTM6300-SP, which is a thermal interface material that can efficiently conduct the heat generated by LED lights. As the size of the LED is shrinking, the response speed is increasing, and the power is increasing, more and more heat will be generated in the limited space, which will damage the performance of the LED. If the LED is overheated, the light will become dim, the color will become lighter, and the service life will be shortened.

Since LEDs are semiconductor devices, they require more precise thermal management than traditional light sources. Honeywell's thermal management materials can solve this particular problem and effectively conduct heat in semiconductor applications.

"Honeywell is committed to the development of energy-saving technologies. The newly developed thermal management materials can improve the performance of energy-saving LEDs, which once again reflects our efforts in this regard." Brian Daniels, Chief Technology Officer, Honeywell Electronic Materials Said. "In a series of phase change materials developed by Honeywell Electronic Materials for the growing LED industry, LTM6300-SP is the first."

LTM 6300–SP is designed for LED backlights of flat panel displays, but the packaging technology can also be used on LEDs used in many other industries, from the automotive industry to the computer industry, with a wide range of applications. Honeywell LTM 6300-SP is a phase change material (PCM) with high thermal conductivity, which is better than silicon-based products that usually overflow and degrade at high temperatures.

The lighting industry is under continuous development, and more energy-saving solutions such as fluorescent lamps and LEDs are gradually replacing incandescent bulbs. The demand for LEDs is increasing because compared with traditional light sources, LEDs have many advantages, such as low energy consumption, longer service life, and smaller size. With the same use of one watt of electricity, LEDs produce more light than incandescent bulbs, are more durable, have faster response times, and contain no mercury. Using LEDs to replace traditional light sources can also reduce pollution and carbon emissions, because LEDs consume less power and can save energy, thereby reducing carbon dioxide and mercury emissions.

The research and development basis of phase change materials is Honeywell's packaging technology in the field of thermal management. Honeywell LTM 6300-SP is mainly used in screen printing, which complements Honeywell's other thermal interface products.

Honeywell Electronic Materials is part of Honeywell Special Materials Group, which mainly provides microelectronic polymers, electrochemical preparations and other advanced materials. These materials can be used in customers' factories to help them realize cutting-edge processing technology. . Honeywell's metal materials division also provides a wide range of products, including physical vapor deposition (PVD) objects and coil assemblies, precious metal thermocouples, and materials for thermal management and electrical interconnection in the back-end packaging process .
