How do LED lights have future ？

For led chips, the target efficiency for 2012 is >80 lm/W. Epistar's vice president of research showed off the new high voltage LED, or HVLED, which promises to narrow the gap between cold white-light and warm white-light tech. Comparitively, Mark McClear of Cree LED Components, said that the US has "highly favourable" policies for LED development, and that the next step in the States is lower costs, better LED luminous efficacy and the standardisation of products
A major talking point, introduced by Roger Chu, research director at LEDinside, is that for Led lighting to be adopted as general Lighting, government subsidies will be required. Chu also said that within the special application market, demand for lighting can be developed through enhancing LED characteristics - so that's building on vertical integration all across the board.
Bigwigs in lighting manufacturers such as Philips and Panasonic have realised that for LED to do well it needs total vertical integration all the way from chips to light source systems.
Everlight's Bernd Kammerer, who has an excellent name, said that led lighting is the way forward: they're more energy efficient and the amount of LED streetlight installation is set to grow from 810,000 lamps globally from 2012 up 42 percent in 2013, with an expected total of 970,000 units. The market will continue to develop and become even more environmentally friendly in the future, while prices will drop as adoption increases in an effort to replace traditional lighting. Justin K. Yang of Veeco Instruments agrees, saying that the next generation of MOCVD will ramp up mass production of LED lights, improving yield rate and lowering cost. Thanks to the increased popularity of MOCVD, LED TV market penetration can be expected to reach a huge 85 percent by 2013, he reckons.
