Scientists design LED 100 times smaller than normal ones
A University of Miami professor at the College of Engineering, Jizhou Song, has helped design an light-emitting diode (LED) light that uses an array of diodes 100 times smaller than the usual ones we see.
The new device has flexibility, maintains lower temperature and has an increased life span over existing LEDs.
In this study, the scientists focused on improving certain features of LED lights, like size, flexibility and temperature.
Song”s role in the project was to analyze the thermal management and establish an analytical model that reduces the temperature of the device.
“The new model uses a silicon substrate, novel etching strategies, a unique layout and innovative thermal management method,” said Song, co-author of the study.
“The combination of these manufacturing techniques allows the new design to be much smaller and keep lower temperatures than current LEDs using the same electrical power,” he added.
The findings are published online by the “Proceedings of the National Academy of Sciences.”
