LED Brightens The Future
 
Article Introduction
The development of led in last few years has been tremendous. The growth of led will grow from $ 5.0 billion in 2006 to $10.8 billion in 2010 and reach $ 17.4 billion in 2013.

Article Description
LEDs have always been something, which have undergone changes regularly. Let it be anything, LEDs always had some important role to play. LEDs started coming to the front due to their unique ability to use less power and last long, opposed to traditional light sources that used a filament for illumination.

Today, special deposition techniques have made it possible to fabricate LEDs with much higher brightness (HB-LEDs) than traditional devices. High-brightness LEDs use latest gallium-based technologies to convert energy into light more efficiently compared to the older type LEDs, producing enough light even for daylight, outdoor uses. Silicones have found implementation in HB-LEDs for many important requirement - providing electrical and environmental safety, increasing light-extraction, minimizing heat build-up and forming lenses that provide options for specific light distribution design and intensities. Silicone products offer good compatibility with standard LED substrates and processing techniques. Their use greatly improves HBLED device reliability and longevity. The special features of high bright LEDS includes better illumination, long life, less cost and it is Compatible with Lead-free Processing. Due to its high adaptability in any device, LEDs are used gadgets and instrument such as Mobile phones, LCD screens, indicator signals, radar detectors, digital cameras, road signs and traffic signals.

By 2010, the combined market for high-brightness LEDs (HB-LEDs) will enter into a new phase of its evolution. The combined market for standard HB-LEDs and the new ultra-high brightness LEDs (UHB-LEDs) will grow from $ 5.0 billion in 2006 to $10.8 billion in 2010 and reach $ 17.4 billion in 2013.
"This is a thriving market even without conventional lighting," says Bob Steele, director of optoelectronics for market research firm Strategies Unlimited. He expects worldwide sales of high-brightness LEDs, the markets largest and fastest-growing segment, to grow about 14 percent annually over the next five years, from US$3.7 billion ($4.8 billion) in 2004 to 7.2 billion (9.4 billion) in 2009.

LED and Optoelectronics
The optoelectronics industry overall growth has been estimated around 18 percent in 2003. The mobile appliances market, mainly mobile phones, has been a key driver in the LED market, reporting 87 percent growth of LED purchases in 2003 over 2002. The mobile phone market has led to a tremendous increase in the use of LEDs for standard applications opening new doors for new opportunities. For example, over 40 percent of mobile phones had color LCD screens in 2003, which increased the use of white LEDs. Handset designers are now choosing color LEDs not only for functional purposes but for aesthetics, too.
New development using LEDs
Scientists first discovered LEDs more than 30 years ago, but they never expected the small points of light to ever serve as anything more than an indicator. Continuing research, however, has shown that LEDs can be made extremely bright and energy efficient.
Researchers at MIT have created a "quantum-dot" organic light-emitting device (QD-OLED) that may one day replace LCDs as the flat-panel display of choice for consumer electronics.

According to scientists, in the upcoming years, LEDs will be used in all application ranging from display panels to room lights to boost health. They foresee development of LEDs to such a level that they will be used for any purpose.
