New Chip Helps to Reduce Power Demand for Lighting by up to 25 Percent

Oct 20, 2003 | Technology Media

Munich, Germany – October 20, 2003 – The new LightMOS™ chip, developed by the German semiconductor manufacturer Infineon Technologies (FSE/NYSE: IFX), helps to achieve significant energy savings in lighting systems while enhancing the comfort of individuals. In the near future, fluorescent tubes will light up like conventional filament lamps without any jitter and even be capable of operation with a dimmer switch. As early as spring 2004, lamps equipped with LightMOS are expected to be commercially available.

In factories, shopping malls and offices, fluorescent tubes are used virtually everywhere to provide artificial light. The LightMOS chip from Infineon is installed inside the so called electronic lamp ballast which supplies the power for the fluorescent tube. Today, around 80 percent of these lamp ballasts still work by magnetic means, using coils, capacitors and an igniter. But new electronic ballasts incorporating power chips are making these bulkier and less reliable components a thing of the past. Electronic ballasts use the power far more efficiently, thereby reducing the power consumption of lighting systems by up to 25 percent. This has the potential to significantly reduce worldwide energy consumption for artificial lighting.

Worldwide demand - around 600 million power-saving chips



The LightMOS chip incorporates a cost-efficient semiconductor technology, called TrenchStop, developed by Infineon. This makes LightMOS chips approximately 15 percent less expensive than alternative devices commonly used in electronic ballasts. Additionally, with TrenchStop technology power losses can be reduced while overall reliability increases. Infineon estimates that the worldwide demand for chips used in electronic lamp ballast by 2005 will be a total of 600 million devices, with some 240 million chips required in Europe alone. The company will begin volume shipment of its LightMOS chip as early as November 2003.

LightMOS chips will be used initially for light fixtures in offices, shopping malls and factory buildings. In the foreseeable future, Infineon’s engineers believe that the new chip will also be used in smaller power-saving lamps in residences, providing even more opportunity to achieve energy savings.
