logixproject.weebly.com5.4 . LED (LIGHT EMITTING DIODE) A light-emitting diode (LED) is a two-lead semiconductor light source that resembles a basic pn-junction diode, except that an LED also emits light. When an LED's anode lead has a voltage that is more positive than its cathode lead by at least the LED's forward voltage drop, current flows.

The Green source color devices are made with InGaN on Sapphire Light Emitting Diode. Static electricity and surge damage the LEDS. It is recommended to use a wrist band or anti-electrostatic glove when handling the LEDs.

www.phys.uconn.eduIn this experiment, you will use the current-voltage relationship of a set of light emitting diodes (LEDs) to measure Planck’s constant. An LED is a semiconductor device that emits electromagnetic radiation at optical and infrared frequencies. The device is a p-n junction diode made from p-type and n-type semiconductors, usually GaAs, GaP or SiC.

Determination of Planck’s constant using LEDs
web2.physics.fsu.eduThe diode will turn on when V= V D. During the recombination energy is released. It can be released in the form of a photon with energy hf ~ Eg, where Eg is the width of the band gap of the semiconductor, which in turn is eV D eV t. The LED junction must be thin and/or transparent so the emitted light can escape. b.
Energy Efficiency of LEDs
www1.eere.energy.govbenchmarks for the efficacy of LED packages and complete luminaires, as well as providing comparisons to conventional technologies. Introduction The energy efficiency of LED products is typically characterized using efficacy, which in basic terms is the ratio of power input to light output—or more technically, emitted flux (lumens) divided
