What started out as 'blue-sky' thinking by a group of European researchers could ultimately lead to the commercial mass production of a new generation of optoelectronic components for devices ranging from mobile laboratories to mobile phones. Allowing doctors to field-test patients and, thanks to a highly portable laboratory, come up with quick results leading to an immediate diagnosis is one of the medical community's most sought-after goals. Projects have been launched all over the world to explore possible ways of doing this, with new methods of miniaturising components very much a key part of developing what ...
Spectrum of a blue/green electroluminescent light source for a clock radio (similar to the one seen in the above image). Peak wavelength is at 492 nm and the FWHM spectral bandwidth is quite wide at about 85 nm. Electroluminescence ( EL ) is an optical phenomenon and electrical phenomenon in which a material emits light in response to an electric current passed through it, or to a strong electric field . This is distinct from light emission resulting from heat ( incandescence ), chemical reaction ( chemiluminescence ), sound ( sonoluminescence ), or other mechanical action ( mechanoluminescence ).

WikiAnswers - How do you fix an LED display on a GE clock radio
led's are not light bulbs, ergo they have no filiment. They seldom fail. You can test the device, by unsoldering one end so it is isolated from circuitry, Then use a volt-ohm-meter on a high scale for ohms. place the leads from the meter (one lead on one end, the other on the other led lead. It is just a diode and should conduct in one direction only. if you get an open on the first try, reverse the meter leads and if the ratio is > 20 to 1 after reversing the leads, the LED is good, and you either have a voltage bias problem or a bad soldier connection. So the diode only conducts in one direction, if it doesn't ...
