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 ).

Theatre Le Grand Rex, Paris, France, partnered with Daktronics, Inc. to light up the façade of its famous, historic building that was built in 1932. Daktronics manufactured and designed two vertical displays, featuring the latest LED video technology that replaced fixed banners, previously used for promotion. The displays are approximately 11.8 meters high by 2.7 meters wide (39 feet high by nine feet wide) with pixels on 23 millimeter spacing. Three custom, curved LED displays were also installed horizontally, mimicking the façade of the building, the displays measure approximately 1.83 meters high by 25 ... industry trends, business articles and survey research

LOFTON: 'Can't Wait' For Iowa
Lofton kept busy during the three-week break in Camping World Truck Series competition by racing in the Nationwide Series, and testing with his Red Horse Racing team. Two weeks ago, Lofton ran the Nationwide event at Loudon, New Hampshire, qualified an impressive ninth, and finished 17th. The laps Lofton logged on the New England track will be put towards good use later in the season when he returns with his RHR team this fall. After Loudon, Lofton trekked to the Gresham Motorsports Park short track in Georgia and shook down his No. 7 Toyota Tundra, with crew chief Mark Rette and the rest of his RHR crew, in preparation for this ... market trends, news research and surveys resources

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 ...
