Nick Holonyak: he came up with the idea of the light-emitting diode in 1962 while he was working for the General Electric Company. You might like to watch a short (4-minute) video about Nick Holonyak's life and work and his thoughts about the future of LEDs (courtesy of the Lemelson ...
The Light-emitting diode is a two-lead semiconductor light source. In 1962, Nick Holonyak has come up with the idea of a light-emitting diode, and he was working for the general electric company. The LED is a special type of diode and they have similar electrical characteristics to a PN ...
If you have a complete working model but do not know which manufactured part to use, you can compare your plots to datasheets to help you decide. To enable this option, set the Modeling option parameter of the Light-Emitting Diode block to No thermal port. To plot the basic characteristics...
Relationship between light efficiency and juction temperature of high power AlGaInP light-emitting diode One of the main problems of high power AlGaInP light-emitting diode (LED) is the heat generated seriously at large working current,which is caused by the w... YX Chen,GD Shen,ZY Gao,......
Before working LEDs could be made, however, cleaner and more efficient materials had to be developed. LEDs were developed during the post-World War II era; during the war there was a potent interest in materials for light and microwave detectors. A variety of semiconductor materials were ...
Using low cost and small size light emitting diodes (LED) as the alternative illumination source for photoacoustic (PA) imaging has many advantages, and can largely benefit the clinical translation of the emerging PA imaging technology. Here, we present
Large-area light-emitting diodes (LEDs) fabricated by mass-production techniques are needed for low-cost flat-panel lighting. Nevertheless, it is still challenging to fabricate efficient large-area LEDs using organic small molecules (OLEDs), quantum dots
The utility model discloses a disassembly working table for an LED (light-emitting diode) television. The disassembly working table comprises a disassembly working table body with a working platform; the working platform is provided with a live shaft and a tray; the upper end of the live shaft...
A light-emitting diode (LED) is mounted on a heat radiating unit therefor. The LED includes a metal carrier having two through holes, and a light-emitting chip packaged on the metal carrier and having a positive and a negative pin fixed to and insulated from the through holes by sintered...
