Investigating LED Efficiency via Multiphysics Simulation
NettetWe fabricated three types of high luminous efficacy white light emitting diodes (LEDs). The first was a white LED with a high luminous efficacy (η L) of 249 lm W −1 and a high luminous flux (ϕ v) of 14.4 lm at a forward-bias current of 20 mA.This η L was approximately triple that of a tri-phosphor fluorescent lamp (90 lm W −1).The blue LED … Nettetfor 1 time siden · Physics World: Engineered bacteria attract cancer-killing radioisotopes into tumors April 14, 2024. Physics World highlighted research led by the University of Cincinnati's Nalinikanth Kotagiri that shows a proof of concept for using engineered bacteria as an adapter to deliver targeted radionuclide treatment to tumors. NettetDiodes can be classified into several types: LED (diode that emits light), laser diode, solar cell, Zener diode, photodiode, and p-n junction diode. They are made of semiconductors like germanium or silicon (group 14 elements). Light Emitting Diode. LED or Light Emitting Diode emits light when the electric current is made to pass through it. greenacre clothing stores
