(AP) -- A third to a half of the Sony Corp. TV sets sold annually will be packed with 3-D features by the year ending March 2013, a senior executive said Thursday. http://www.physorg.com/news178440806.html Technology Thu, 26 Nov 2009 07:30:01 EST news178440806 (PhysOrg.com) -- Of the 1.5 billion people in developing countries who do not have electricity, many rely on kerosene lamps for light after the sun goes down. But now, researchers from Denmark have designed an LED lamp that runs on solar cells, which costs less than one-quarter of the annual cost of using kerosene lighting. The solar-LED lamps are expected to last at least a year, making them an affordable alternative to kerosene. http://www.physorg.com/news176991580.html Technology Mon, 09 Nov 2009 12:20:34 EST news176991580 NXP Semiconductors today announced three major developments in its portfolio of mains connected LED driver solutions: the success of its SSL2101 LED driver IC in matching LED lifetimes in an accelerated lifetime test; the introduction of the SSL 2102 integrated dimmable mains LED driver IC for SSL retrofit lamps and modules; and the launch of its online design tool for SSL applications, which makes it easy for engineers to test the behavior of LED lighting applications based on four NXP products. http://www.physorg.com/news176624365.html Technology Thu, 05 Nov 2009 06:30:02 EST news176624365 Just when you were finally warming up to the idea of swapping out your old light bulbs with compact fluorescent ones, you may soon find a new alternative at your local hardware store. http://www.physorg.com/news175412870.html Technology Thu, 22 Oct 2009 08:10:01 EST news175412870 (PhysOrg.com) -- In full sunlight at mid-day, gold objects are brilliant and richly colored. Put those same objects in a dark interior room with only fluorescent lamps, however, and they will look pale and slightly greenish -- a problem arising from the inability of fluorescent lamps to render the optimal color temperature to reveal gold in its warmest light. http://www.physorg.com/news173638579.html Technology Thu, 01 Oct 2009 18:20:01 EST news173638579 HP today introduced the world's thinnest full-performance notebook PC as well as a slim, stylish consumer notebook that delivers an optimal balance of mobility, performance and affordability. http://www.physorg.com/news172250779.html Electronics Tue, 15 Sep 2009 16:30:02 EST news172250779 (PhysOrg.com) -- A new process for creating ultrathin, ultrasmall inorganic light-emitting diodes (LEDs) and assembling them into large arrays offers new classes of lighting and display systems with interesting properties, such as see-through construction and mechanical flexibility, that would be impossible to achieve with existing technologies. http://www.physorg.com/news169997059.html Technology Thu, 20 Aug 2009 14:25:10 EST news169997059 One way the United States could slash its electricity use, dependence on fossil fuels and emissions of heat-trapping gases is really quite simple: better light bulbs. http://www.physorg.com/news169404880.html Technology Thu, 13 Aug 2009 18:30:01 EST news169404880 (PhysOrg.com) -- Monochromatic light-emitting diodes cover a large part of the visible spectrum with high effi-ciency. For blue light, nitride diodes achieve external quantum efficiencies in excess of 65%, i. e., one photon is emitted for approx. 2/3 of the electron-hole pairs injected into the diode. For red light, phosphor diodes achieve efficiencies of approx. 50%. However, so far no highly efficient monochromatic LEDs have been available for the `yellow gap` at around 560 nm. Now researchers with Philips Lumileds have developed a monochromatic nitride diode that closes this gap. http://www.physorg.com/news167555795.html Physics Thu, 23 Jul 2009 08:17:44 EST news167555795 (PhysOrg.com) -- Scientists have developed a lighting device that can change its color temperature throughout the day, matching the natural daylight chromaticities produced by the sun. Currently, no other type of lighting device is capable of producing this wide a span of sunlight-style illumination, which could make the new technology an attractive future high-quality lighting source. http://www.physorg.com/news166945490.html Physics Thu, 16 Jul 2009 09:00:01 EST news166945490 Anyone who takes underwater photos knows how challenging it is to navigate in the water while holding a camera.

They can provide a pleasing warm light or they can be energy-efficient, but they haven't been able to be both at the same time. http://www.physorg.com/news160766041.html Nanotechnology Tue, 05 May 2009 18:14:31 EST news160766041 (PhysOrg.com) -- Organic semiconductors are promising building blocks for many devices, from LEDs to transistors, offering potential advantages such as cost-effectiveness, flexibility, and high performance. Currently, most research in organic semiconductors has focused on p-channel semiconductors, which transport positively charged holes, rather than n-channel semiconductors, which transport negatively charged electrons. The choice of semiconductor depends on the application, and many applications require a combination of both types. However, the few n-channel semiconductors that exist today have performance that lags considerably behind their p-channel counterparts. http://www.physorg.com/news159789536.html Physics Fri, 24 Apr 2009 10:59:38 EST news159789536 (PhysOrg.com) -- Tiny light-emitting diodes with optical microsystems that can produce all the colors of the rainbow, a new method for producing printed circuit boards - Fraunhofer researchers are showing innovative developments at the nano tech 2009 exhibition in Japan. http://www.physorg.com/news153595435.html Nanotechnology Wed, 11 Feb 2009 17:25:00 EST news153595435 A new way of making LEDs could see household lighting bills reduced by up to 75% within five years. http://www.physorg.com/news152430535.html Technology Thu, 29 Jan 2009 05:49:35 EST news152430535 (PhysOrg.com) -- The Solarbulb, a new lighting gadget from miniWIZ, doesn't exactly come with all parts included: you have to add your own water or soda bottle.
