2010 will be the first application of LED in northern hemisphere countries

With the current hot investment in LED industry, today at the opening of the ShenZhen Railway Station IIC-China, various LED scheme has become the focus of manufacturers shows, whether NXP, TI, Intersil and other international well-known manufacturers, or China domestic IC manufacturers, LED lighting solutions become the focus of show. And in the morning to "open a new era of green energy is the first day of LED lighting display the theme from the national high-tech enterprise development most incisive, LED Zheng Haowen, NXP director of Specialized Committee and STMicroelectronics experts demand from the global demand to China, from the industrial chain of LED carried out a detailed analysis to the related IC the technology.

"The demand for LED is moving from government projects to the general lighting market, the country's 11th Five-Year plan is to achieve five major lighting companies in China, and the formation of the international lighting giant competition. Zheng Haowen said in a keynote speech, LED as a new generation of lighting products in the next 20 years will quickly occupy the lighting market. China's rise in the LED general lighting market, the introduction of LED's global competition in the Chinese market, in 2015 China will create a global market for LED lighting. "However, he believes that Chinese companies need to merge and integrate to form a certain scale in order to fight against the international giants.

Zheng Haowen analysis, on the LED general lighting, 70-80lm/W luminous efficiency is sufficient, the illumination of LED lighting than traditional lamps (including energy-saving lamps) can save energy 50-60%. Today's mainstream technology has reached this level. High end 130lm/W products have been commercial, CREE is the end of last year launched the 180lm/W chip LED. "But the current problem is that consumers believe that LED lighting only power, do not save money, mainly due to the electricity market in China is too cheap led to. "He explained that in the European electricity the cheapest country is Hungary, about 1.8 yuan / kWh, while in Germany it is up to about 10 yuan / kWh, but Chinese electricity will increase, 1 yuan / kWh more than likely, state subsidies will not last long, so LED lighting is not only power and money. "

Although Zheng Haowen advocated industrial convergence set for large quantity, small enterprises, not too scattered, so that we can compete with international giants, but the market manager of Greater China NXP lighting products Chen Rong said: "the LED market will be a thousand fold increase in the market, we have the opportunity, big play, small play, do not necessarily have to be bigger. "

He came up with a set of data analysis: last year, the global LED bulbs sold up to 10 million, which is a very meaningful data, indicating that LED lighting into a new milestone. "However," he said, "shipments of 10 million LED bulbs is less than 15 billion of the world only 1/1000 of incandescent lamp. So, now invest in LED lighting industry, is to seize the dark horse. "

Like Zheng Haowen, he thinks LED is best suited for indoor lighting. He is very vivid metaphor: "LED lighting industry relative to the incandescent industry is the wolf, and now we are crying wolf, the sheep can live for a few years? However, our energy-saving lamp technology can make sheep into pleasant goat, gray wolf, pleasant goat can also live a few years. Chen Rong said last year, 3 billion of the global energy saving lamps, accounting for about 20% of the entire lighting market, the world's 90% energy-saving lamps in china. However, the current energy-saving lamps are a lot of complaints, in particular, can adjust the lights, both expensive and quality problems. The reason is very simple, the current 90% of the energy-saving lamps are made with a separate device, multiple devices will be a problem, the product life expectancy is usually less than the nominal value. "He said, NXP uses the most advanced technology to replace the expensive dimmers (currently $40), like the incandescent lamp as the cost of light; NXP also uses a highly integrated IC to the design of energy-saving lamps, the energy-saving lamp life," the EU also supports the use of chip solutions. He said.

However, in the end, we still have to move forward to LED lighting, he was very funny, said, we all know that LED is a diode, and now the diode is sold by the pound, one day LED chips will be sold by catty. "It sounds like a dream at the moment, but it's likely to turn out to be true from the rapid price trend of the LED chip. However, the cost of LED lighting is not the most important in the LED chip, will be in the packaging, drive and system costs. Even if one day LED chips can be sold by catty, other devices still need to press the "dollar" to sell, here on chip company said, at present you the most intense competition is how to improve the efficiency and reduce the cost of the driving part.

The conference on the launch of a Intersil high brightness unipolar LED driver IC (ISL6721) is recommended. Similarly, in the TI booth, they launched the latest efficient AC input multi string LED lighting drive IC - UCC28810. "This scheme is lower than the constant voltage scheme, and provides a buck mechanism for each string architecture. TI booth, said the site engineer.
