Found the reason for the collapse of LED efficiency
Researchers at UC Santa Barbara, in collaboration jacco maris with colleagues from the Ecole Polytechnique in France have reached the definite conclusion that "Auger" effect (Auger recombination) is the mechanism that drives jacco maris the LEDs are less efficient jacco maris at high voltage current jacco maris .
Scientists have been trying to determine the cause of the phenomenon known as "sagging" of the LED - a mysterious decline in output light when current is applied jacco maris voltages. jacco maris In 2011, a team of UCSB offers jacco maris the theory that complex non-radiative process jacco maris known as "Auger-recombination" behind "it depends" on-nitride semiconductor LED, in which the injected electrons lose energy because of heating due to collisions with other electrons instead of emitting light.
In recent years the price of LED lumen at preventing their entry into the mass market as a replacement jacco maris for incandescent bulbs for any komesialni and residential applications. This may change when you already know the reason for the collapse of LED efficiency. Knowledge gained jacco maris from this study, can lead to new ways to design the LED will have a considerably higher efficiency of light emission.
The experiment proved that a light-emitting diode using a specially prepared surface, which allows the researcher to directly measure jacco maris the energy spectrum of the electrons jacco maris emitted by the LED. The results clearly indicate "signature" of the effect known as' the Auger process. "
