Uncover the real reason for the LED light bulb "light effect down"

The phenomenon of "light efficiency decline" is that when the input power is larger, the luminous efficiency of LED will be reduced by nearly 20%. The phenomenon was first reported in 1999, has been an important obstacle restricting the development of LED lighting industry. Reported that, in a paper published in the latest, the School researchers confirmed that a phenomenon called electronic leakage is the culprit leading to the decline in the effectiveness of LED bulbs light.

According to physicist organizational network (Phys.org) reported that the latest findings of researchers at Rensselaer Polytechnic Institute, will reveal the real reason for a long time LED bulbs, light efficiency decline (LEDdroop) phenomenon.

The discovery is expected to lead the LED lighting industry to break through the bottleneck of major development. The phenomenon of "light efficiency decline" is that when the input power is larger, the luminous efficiency of LED will be reduced by nearly 20%. The phenomenon was first reported in 1999, has been an important obstacle restricting the development of LED lighting industry.

Reported that, in a paper published in the latest, the School researchers confirmed that a phenomenon called electronic leakage is the culprit leading to the decline in the effectiveness of LED bulbs light.

The findings, the researchers said, provide the first comprehensive model to investigate the decline in light efficiency, which will lead to new technologies to solve the problem.

For a long time, researchers and LED manufacturers have been committed to reducing the loss of LED light effect, but did not really lead to the real reason behind the phenomenon.
