Energy Efficiency

Lighting

The focus of lighting research at USC is in Light Emitting Diodes or LEDs, a semiconductor light source. LEDs today are widely used as indicator lamps in many devices, but are increasingly becoming available for use in al lighting applications. LEDs are significantly more efficient that other forms of light (including incandescent and fluorescent) but is more expensive.

There are two main efforts at USC in LEDS. The first is to improve LEDs that emit at visible wavelengths, using nanoscale patterning to create designs which are both cheaper to make and emit light more efficiently.

The second is focusing on organic light-emitting devices (OLEDs). OLEDs have attracted a great deal of attention due to their potential use in lighting as well as in panel display applications. An organic compound is any member of a large class of chemical compounds whose molecules contain carbon. The research is focused on finding mew set of organic materials that can reduce the cost and improve the efficiency of LEDs in a variety of applications.
