LED lighting future getting brighter

In general lighting as well as in automotive lighting and many other market segments, LEDs are becoming increasingly popular for their longevity and energy efficiency. Nevertheless there are some obstacles and caveat a user should know to get really successful implementations. The market size for high brightness (HB) LEDs is expected to reach $20.2 billion by 2015—a CAGR of 30.6 per cent from 2012 (according to Strategies Unlimited). One of the key application areas driving this significant growth factor are the LEDs used to backlight thin film transistor (TFT) liquid-crystal displays (LCDs). Applications range from high definition (HD) TVs and portable tablet PCs to automotive displays and a myriad of handheld communication devices.
