Zetex LED driver to reduce the cost of LED, lighting China semiconductor lighting industry

In October 21, 1879, the American scientist Edison invented the incandescent bulb, so that people bid farewell to the darkness of the night, into the era of electrical lighting. However, in the green energy saving common practice today, a significant advantage of white LED by virtue of its low energy consumption, long service life, energy saving light source from a variety of talent shows itself, is leading the global acceleration to a new era of transition of semiconductor lighting.

LED applications include display screen, security and safety lights, building lighting, camera flash and automotive lighting, etc.. However, the relatively high cost of LED lighting is currently not able to get a major obstacle to rapid popularity. In order to make the products more competitive in the cost of LED, which gained popularity in the broader application areas, Zetex Semiconductors company (Zetex) at the Twelfth International Conference & Exhibition integrated circuit (IIC-China), to the number of LED lighting equipment manufacturers show a series of low cost and high efficiency of the LED driver IC, such as ZXLD1350/1360/1362.

Among them, Zetex showed a ZXLD1360 LED driver IC, the output current of the products up to 1A, supports up to 5 3W on the LED, the rated operating temperature range of -40 DEG C to 125 DEG C, can handle up to 40V transient voltage flows for LED automotive, industrial, construction, emergency rescue lighting circuit and daily lighting applications based on.

Zetex semiconductor company special standard products division chief marketing director Mr. Luo Guowei said: "compared with the previous products, the main advantage of ZXLD1360 LED driver, the heat dissipation efficiency enhancement type structure is as high as 95%, the height of the integrated component can create more compact LED lighting solutions. "

Luo Guowei said that the company has been in the past to provide a simple component can now be able to provide a complete set of LED driver solutions. Zetex has set up an office in Shenzhen last year, and 3 application engineers can provide a reference design for mainland customers.

Zetex company in 2005 annual sales of $104 million, including lighting products accounted for 10% of total sales, while in 2006 the annual sales revenue reached $124 million, is expected in 2010 will further grow to $300 million. According to UBS data, in 2005 the global white light LED market size of $800 million, as of 2010, the market size will be strong expansion to $12 billion, an average annual compound growth rate (CAGR) up to 26%. Luo Guowei stressed that due to the high growth potential of the LED market, Zetex will be the future of LED lighting as one of the priorities of the business, to further expand its proportion in the company's overall sales.

Luo Guowei also pointed out: Zetex full range of products have been successfully completed lead-free conversion, in addition to access to the title of green partner Sony Corp, and Samsung Corp Eco-Partner title. "Turning just went into effect on March 1, 2007 China" electronic information products pollution control management measures ", Zetex Asia Pacific Sales Vice President Li Jinhua said, because Zetex fully comply with EU RoHS requirements, so do not worry about Chinese RoHS what is the impact on the company's sales. At the same time, the price of lead free products has not changed much, so it will not increase the cost to customers.

There is news that the current China energy shortage, LED lighting can achieve the purpose of power saving, as long as there is a 1/3 incandescent lamp is LED lamps replaced each year will be able to save nearly 100 billion of electricity, equivalent to an annual generating capacity of the Three Gorges project. 2004, Shanghai, Dalian, Xiamen, Nanchang, 4 cities have been set up as a national semiconductor lighting industrial base, Shanghai has been the core of semiconductor lighting as a pillar industry.

With the 2008 Beijing Olympic Games is approaching, I believe the Olympic effect will further drive the LED display screen, rising building lighting products demand on the outside, then LED will not only light the landmark, lit 10000 window, will light a sunrise industry worth billions.
